2.0 Installation

Review this section and the Important Product Safety Instructions on the front inside cover before proceeding with the installation of your remote.

WARNING: Installations should be performed by qualiﬁ ed per-

sonnel, such as a licensed or certiﬁ ed electrician. The installer determines which safety codes apply and ensures all applicable installation requirements are followed. Applicable installation codes vary depending on the speciﬁ c location and application.

CAUTION: When connecting battery power to the inverter, all

battery negative connections must be connected prior to the battery positive connections. When removing battery power from the inverter, the battery positive should be removed before any battery negative connections are disconnected. This prevents any communication chips/lines from becoming the DC return path to the battery— causing permanent damage to all connected accessories.

Summation: Ensure all battery negative circuits are always con-

nected before connecting or disconnecting battery positive.

2.1 Pre-Installation

Before proceeding, read the entire Installation section to determine how best to install your ME-ARC remote. The more thorough you plan in the beginning, the better your inverter needs will be met.

2.1.1 Installation Guidelines

• Before connecting any wires determine the remote’s cable route throughout the home or vehicle/boat, both to and from the inverter.

• Always check for existing electrical, plumbing, or other areas of potential damage BEFORE drilling or cutting into walls to mount the remote.

• Make sure all wires have a smooth bend radius and do not become kinked.

• If installing this remote in a boat, RV, or truck ensure the conductors passing through walls, bulkheads, or other structural members are protected. This minimizes insulation damage (such as chaﬁ ng) which can be caused by vibration or constant rubbing.

2.1.2 Unpacking and Inspection

Carefully remove the ME-ARC remote from its shipping container and inspect all contents. Verify the following items are included:

• The ME-ARC remote display

• Bezel

• 50’ remote cable

• Eight #8 x 3/4 Phillips screws

• ME-ARC owner’s manual

If items appear to be missing or damaged, contact your authorized Magnum Energy dealer or Magnum Energy. Save your proof-of-purchase as a record of your ownership; it is needed if the unit should require in-warranty service.

2.1.3 Tools Required

Installing the remote control is simple and requires the following tools:

• Phillips screwdriver • Level • Drill

• Cut-out tool (knife/saw) • Pencil • Drill bit (7/64”)

2.0 Installation

2.2 Connecting the Remote Cable

The ME-ARC comes with a remote cable to enable communication between the inverter and the remote. The remote cable is a 50-foot, 4-conductor, round, telephony standard with 6P4C (6-position/4-conductor) connectors on each end. When the 6P4C connectors are held side by side with both of the connector tabs facing the same way, the color of the conductors in each connector is the opposite from top to bottom (as shown in Figure 2-1).

Note: The remote cable can be extended up to a length of 200 feet without

data degradation.

2.4 Mounting the ME-ARC Remote

The ME-ARC can either be ﬂ ush mounted (through an opening in the wall), or surface mounted using the provided bezel. Find a location that is clean, dry and protected. Allow room to access the remote’s SELECT knob and to view the LEDs/display.

CAUTION: Ensure that no AC power is connected to the inverter,

and then according the your inverter owner’s manual correctly connect the inverter to the batteries.

CAUTION: Always check for hidden electrical wires, pipes and cables

BEFORE drilling, cutting, or screwing into walls or cabinets.

2.4.1 Flush Mount Installation Procedure

To ﬂ ush mount, the wall opening must have at least a 2” (5 cm) depth to allow room for the remote and the cable.

1. Cut an opening in the wall (Figure 2-5). Ensure there are no openings

around the display and enough material for the screws to secure the unit.

2. Drill four pilot holes for the #8-32 screws that will attach the remote to

the wall (refer to Figure 2-3 for hole locations and dimensions).

3. Route one end of the cable through the wall cutout to the inverter/charger,

and then plug it into the RJ11 REMOTE port (blue label) on the inverter/ charger—inverter has DC power, but is OFF. See Figure 2-2.

4. Take the other end of the remote cable and while plugging it into the

back of the ME-ARC, view the remote’s display to ensure the Power-up Self Test initiates (see Section 2.5).

5. If the self test is successful, secure the ME-ARC to the wall using four of

the supplied Phillips screws. If the self test is unsuccessful, refer to the Troubleshooting section.

3.2 Remote Feature to Inverter Compatibility

The ME-ARC has many settings and is designed to work with the advanced features in your Magnum inverter—and/or other Magnum devices (i.e., MEAGS-N or ME-BMK). The ME-ARC communicates with your inverter to allow the set up and enabling of these advanced features. However, when the ME-ARC is released with new software, some of the features and functionality in the remote may not be available in an inverter or networked accessory that has an earlier software level. In this case, the advanced setting is not recognized and will not function. Use the steps below to help you determine which MEARC (Revision 3.0) menus/features are compatible with your inverter.

1. Go to: http://www.magnumenergy.com/Service/Compatibility.htm to determine y

2. Use Table 3-1 to determine which ME-ARC ‘features/settings’ you want to use and what inverter compatibility level is required (see the “Model/ Level Required” column in Table 3-1).

3. If your inverter compatibility level is the same or greater than the level required, your inverter can support the device setting/feature you want.

4. If your inverter does not have the required compatibility level for a feature/setting you want, contact Magnum Energy for a software upgrade.

3.3 Remote Buttons and Menu Items

The ﬁ ve menu buttons (FAVS, CTRL, METER, SETUP, or TECH) allow the inverter/charger system to be conﬁ gured to your speciﬁ c preferences. These buttons also allow you to access menu items that can help with monitoring and troubleshooting your system. Refer to Figure 3-2 for an example on how to navigate the remote.

This section covers each menu button’s function and its various conﬁ gurable settings. This helps optimize the operation of the inverter/charger.

3.3.1 FAVS Button and Menus

The FAVS (FAVORITES) button is similar to the Favorites button on your TV remote. It enables you to store the most frequently used menu items for quick reference, or to make easy changes to the system. The menu items stored under the FAVS button should be those menus most often used.

The FAVS button has ﬁ ve factory-stored default menu items. You can also access these menu items using the SETUP and CTRL buttons to make changes. Before changing the default FAVS menu items, it is suggested that you thoroughly review all the menu items on the menu map (see Figures 4-1 thru 4-5) and make a short list of the items you think you will use most often. Once you decide which ﬁ ve items you would like to make as your favorites, determine the order in which those menus are to appear under the FAVS button. This is important since you will assign a FAVS position 1-5 for each menu item you select.

Menu items can be changed at any time under the FAVS button. Navigate to a menu item that you would like to set as a favorite, then push and hold the FAVS button for three seconds. The screen displays “Select FAV: F1“ on the bottom line. Rotate the SELECT knob to select FAVS 1 through 5. Once you have decided the location for the menu item, press the SELECT knob to save the menu item at the selected FAVS location.

Info: The FAVS button can be used to store menu items that would

otherwise not be accessible after a PIN has been set for the SETUP menu.

Info: Menu headings cannot be selected and stored in FAVS,

only menu items (with exception of TECH menu headings). Menu headings are identiﬁ ed with a number. Menu items are identiﬁ ed by a number followed by a letter.

Example: 02 Invert Setup is a menu heading.

Example: 02A Search Watts is a menu item.

(FAVS #2). Refer to the SETUP button’s 02B LBCO Setting menu item on page 24 for information on how to adjust the LBCO setting.

• FAVS: F3 AC Input – This is the F3 default (FAVS #3). Refer to the

SETUP button’s 03A AC Input Amps menu item on page 28 for information on how to adjust the AC Input setting.

• FAVS: F4 Battery Type – This is the F4 default (FAVS #4). Refer to the

SETUP button’s 03B Battery Type menu item on page 30 for information on how to set the battery type.

• FAVS: F5 Gen Control – This is the F5 default (FAVS #5). Refer to the

CTRL button’s 03 Gen Control menu on page 18 for information on how to use the Gen Control function.

Info: F5 Gen Control is a menu heading. It provides easy access

to turn the generator on and off. If another menu item is saved in the F5 location, the only way to bring Gen Control back into the F5 location is to reset the remote to its factory defaults using the TECH button’s 07 Load Defaults menu.

Page 22

3.0 Setup

3.3.2 CTRL (Control) Button and Menus

The CTRL button accesses the 01 ACIn Control, 02 CHG Control, and 03 Gen Control menus. The CTRL button gives you quick control of the main functions

of the inverter/charger without having to access the SETUP button’s menus in order to change the operation of the inverter/charger or generator. Once the settings have been programmed in the SETUP menus, the features can then be enabled using the CTRL button.

Example: The SETUP menu’s 02C AC In - Time setting is used to set what

time of day (e.g., 12AM to 8AM) you want the inverter to connect to the incoming AC. Once the time is set, use the CTRL button to access the Set ACIn Control menu item and select Time Connect. When Time Connect is selected, the inverter/charger will only connect to AC when the time is between 12AM and 8AM.

Info: If a ME-ARC is connected to a parallel system with a ME-RTR,

it acts like a ‘display only’ device with limited user controls. When the ME-ARC is directly connected to either the inverter or ME-RTR, the CTRL button function of the ME-ARC is defeated.

The ME-ARC however, does contain the 03 Gen Control selection in the FAVS menu. The generator can be controlled via the ME-ARC through the FAVS menu, but not thru the CTRL menu.

CTRL: 01 ACIn Control

01 ACIn Control menu has four different conditions in which the inverter/charger will connect to an incoming AC power source. Only one may be selected at any one time—multiple conditions can be enabled, but only one can be active.

Info: Before the inverter allows the AC input to connect to the AC

source (grid or generator), the incoming AC must be qualiﬁ ed by the inverter/charger (voltage is below the high AC input requirements, above the SETUP button’s 03D VAC Dropout setting, and between 50 Hz to 70 Hz for domestic models—40-60 Hz for export models).

Info: The top status line of the LCD display will alternate the in-

verter/charger status with a secondary AC IN status when AC is present, but is not connecting as a result of a selection made in the SETUP menu.

Example: AC is present, but Time Connect has been selected from

the 01 ACIn Control menu and the current time of day is 6PM. The SETUP menu’s 02C AC In-Time current setting is 2AM - 8AM. The current time of 6PM is outside the connect time, so the inverter/ charger will not connect to the incoming AC until after 2AM. The primary status will display “Inverting” and the secondary status will display “Time Connect” to let you know the reason that incoming AC has not connected.

• Auto Connect – Automatically connects to incoming AC power when the

incoming AC is qualiﬁ ed by the inverter/charger (voltage is below the high AC input requirements, above the SETUP button’s 03D VAC Dropout setting, and between 50 Hz to 70 Hz for domestic models—40-60 Hz for export models).

• VDC Connect – Only allows the incoming AC to connect when the DC

battery voltage falls below the Set Connect Volts setting in the SETUP menu’s 02D AC In - VDC menu item. Disconnects from incoming AC when the DC battery voltage rises above the Set Disconnect Volts setting, also from the 02D AC In - VDC menu.

Info: See SETUP menu 02D on page 26 for a complete explanation

of the Set Connect/Disconnect Volts menu settings.

• Time Connect – Only allows incoming AC to connect when the time of

day is between the Set Connect and Set Disconnect time settings in the SETUP menu’s 02C AC In - Time menu item.

Info: See SETUP menu 02C on page 25 for a complete explanation

of the Set Connect/Disconnect time menu settings.

• SOC Connect – Only allows incoming AC to connect when the battery

bank State of Charge (SOC) falls below the Set Connect SOC setting in the SETUP menu’ ing AC when the battery bank SOC rises above the Set Disconnect SOC setting, also from the 02E AC In - SOC menu. This feature requires the optional ME-BMK (battery monitor) to be installed.

• AC In-Disabled – Disconnects incoming AC when selected. This setting

will prevent incoming AC from connecting to the inverter/charger.

Page 24

3.0 Setup

CTRL: 02 CHG (Charge) Control

02 CHG Control enables you to set the Charge mode to Multi-Stage, Force Float, or to Restart Bulk. Most of the time the charger should be left in the Multi-Stage setting, but to override this setting use the CTRL button and the 02 CHG Control menu. The charger can be forced into the Float mode or you

can start the Bulk mode using the Force Float or Restart Bulk settings from the CTRL button’s 02 CHG Control menu.

• Multi-Stage – This charge proﬁ le starts in Bulk mode (maximum cur-

rent). It transitions to the Absorption stage (constant voltage). When the Absorption voltage is reached (as determined by the SETUP button’s 03E Absorb Done menu), it transitions to the ﬁ nal charge stage as selected in the SETUP menu’s 03G Final Charge Stage menu item.

Info: Multi-Stage must be selected in order for the Final Charge

Stage setting to be used.

• Force Float – This charge proﬁ le forces the charger to stay in Float mode

as long as AC is present and the charger is active. Force Float is most often used when another source of charging such as PV, wind, or hydro is available to keep the batteries at or above the ﬂ oat voltage. If AC is disconnected and then reconnected, the charger will go directly to Float mode and will not initiate a Bulk or Absorption charge cycle.

CAUTION: Using the Force Float setting may not fully charge the

batteries. Most batteries require a Bulk and Absorption charge cycle in order to fully recombine the electrolyte in the batteries and bring the speciﬁ c gravity to the proper level. Be sure to check with your battery manufacturer before using this setting.

Info: If Silent is selected from the SETUP menu’s 03G Final Charge

Stage menu item, you can override this selection with Force Float

to temporarily ﬂ oat the batteries.

• Restart Bulk – This selection restarts the Bulk cycle from any stage in

the charge cycle. The Restart Bulk setting is useful when a full multistage charge cycle does not bring the speciﬁ c gravity of the batteries to the proper level.

Info: The Restart Bulk setting automatically defaults back to the

Multi-Stage setting once the inverter/charger status displays “Bulk Charging”.

Info: If you have to continually restart the bulk cycle in order

to bring the batteries to full charge, check the settings from the SETUP button’s 03 Charger Setup menu to ensure the batteries are fully charged at the end of a regular multi-stage charge cycle. Check with the battery manufacturer for proper battery charger settings.

CAUTION: Frequently restarting the Bulk cycle may result in over-

charging of the batteries.

CTRL: 03 Gen Control

03 Gen Control is used for controlling a standby generator that is connected to the system and using the optional ME-AGS-N module. Once the AGS-N

Page 25

3.0 Setup

is installed in the system, the generator can be manually started and stopped, or set to start and stop automatically from this menu.

Info: If a ME-ARC is connected directly to one of the communication

ports on a router (P1-P6) it can be used in a remote location as a remote on/off switch, as well as to assist in monitoring the system and to control a generator that is connected to an ME-AGS-N.

Info: The ME-AGS-N must be installed in order for the 03 Gen Con-

trol menu to control a standby generator. Refer to the ME-AGS-N

Owner’s Manual (PN: 64-0039) for installation information.

• OFF – The OFF selection will stop the generator by sending a ‘stop’ com-

mand from the ME-AGS-N control module (can be running from either a manual start or an autostart command from the AGS). When the OFF setting is selected, the generator will not start automatically.

Info: If DC power is lost to the remote, this menu resets to the

default OFF selection for safety.

• ON – The ON selection starts the generator by sending a ‘start’ command

from the ME-AGS-N control module. Once the generator is started, it may be stopped by selecting OFF from the 03 Gen Control menu, which sends a stop command from the ME-AGS-N.

Info: Manually start the generator by selecting ON from the 03

Gen Control menu; change the selection to AUTO to automatically

stop the generator. When the AUTO setting is selected after the generator has been manually started, it uses the stop setting from the SETUP button’s 04A Gen Run VDC (using the Set Stop Gen Volts setting—even if not enabled) or 04F Max Gen Run Time menu item, whichever occurs ﬁ rst.

Info: The ON selection uses warm-up time. The OFF selection stops

immediately and does not use the cooldown time.

• AUTO – This selection uses the settings from the SETUP button’s 04 AGS

Setup menus to automatically start and stop the generator based on

battery voltage, time of day, AC load on the inverter, high temperature, or battery state of charge (requires a ME-BMK/ME-BMK-NS accessory). Refer to the Section 7.0 “Using an AGS Module” to set the start and stop parameters for the generator.

3.3.3 METER Button and Menus

The METER menu button gives you access to the various meters which help determine the status of the inverter/charger and battery system.

Info: Depending on the inverter, some meter functions may not

display or be accessible. If some meters do not display, refer to Section 3.2.

Info: Most displays automatically return to the remote’s home

screen ﬁ ve minutes after the last button push. When using the METER button, the selected menus stay and do not return to the remote’s home screen. This feature is useful for displaying commonly used meter readings.

METER: 01 DC Meters

DC Meters displays battery voltage, DC amps from the inverter/charger, and the time in Charge mode. Use these meters to monitor your battery bank.

• 01A DC Volts – DC Volts provides the battery voltage. The DC Volts

display provides the voltage from the battery bank connected to the inverter. Accuracy is ±1.5% with a 0.1 VDC resolution.

• 01B DC Amps – The DC Amps meter displays a negative number to

show the current being removed from the battery. This meter displays a positive number to show the amount of current delivered to the batteries. This meter converts AC amps to display DC amps, so the accuracy below one amp AC (~10 amps DC @ 12 VDC) is not detected. When the current in or out of the batteries is greater than one amp AC, the accuracy of this meter is ±20%.

• 01C Charge Time – This meter displays the total time the charger is in

the Bulk or Absorb mode. The meter does not accumulate time when in Float, Charger Standby, Full, or Silent mode.

Info: The charge time is reset whenever the charge status goes to

“Charging” (occurs whenever AC is connected to the inverter/charger), or if the charger initiates another Bulk Charge cycle.

METER: 02 AC Meters

• 02A Output Volts – This menu provides the AC voltage measurement at

the inverter’s output terminals. If inverting, this measures the inverter’s output voltage. When in Standby mode, this measures the AC voltage that is passing through the inverter from the source (e.g., grid or generator).

• 02B Output Hertz – While inverting, this menu displays the output

frequency of the inverter. When in Standby mode, this meter displays the frequency of the incoming AC source (i.e., grid or generator) that is passing through the inverter to the inverter’s output terminals. The frequency is shown in Hertz (Hz).

• 02C Load Amps – This menu displays the AC amps as measured on the

inverter’s AC output terminals. The reading is positive (+) if power is being pulled from the inverter to run an AC load—either using the batteries in Inverter mode, or from the AC input source in Standby mode. The reading is negative (–) to indicate power is being returned to the inverter through the AC output terminals—possible in an AC coupled installation.

Info: The 02C Load Amps value is determined by subtracting the

02E Inv/Chg Amps value from the 02D Input Amps value.

Page 27

3.0 Setup

02D Input Amps – This menu displays the total AC amps being used

by the inverter for charging and any connected load at the output of the inverter. This reading is always displayed as a positive (+) number.

Example: If the charger is using 20A from the AC source and the load

connected to the inverter output is using 10A, the combined load on the incoming AC source is 30A. So, 30A is displayed as the input amps.

• 02E Inv/Chg Amps – This menu displays the inverter or charger amps.

A negative (–) amps reading indicates the inverter is powering the inverter loads and the batteries are discharging (inverter amps). A positive (+) amps reading indicates the inverter is using the AC input source to charge the batteries (charger amps).

Info: The 02G Input AC2 menu only displays if the remote is con-

nected to a dual source inverter/charger that has an AC1 and AC2 input such as the MSH4024E.

Info: If the 02G Input AC2 menu displays voltage (~ 50 volts),

but the generator is off or nothing is connected to the AC2 input, the AC2 neutral-to-ground bond connection is not correct or connected.

3.3.4 SETUP Button and Menus

Pressing the SETUP button provides access to the menu items and settings that enable you to conﬁ gure the ME-ARC display, inverter/charger, ME-AGS-N, and the ME-BMK. Review each menu item to determine if you need to adjust any settings to meet your system requirements.

Info: The ﬁ rst screen that may appear when the SETUP button is

pushed is a password screen. If the PIN has been set under the TECH button’s 05 SETUP PIN menu item, the ﬁ rst screen is the Setup PIN menu. The proper PIN must now be entered in order to access the SETUP menus. After ﬁ ve minutes from the last button push, the display automatically returns to the remote home screen and the PIN must be reentered in order to access the SETUP menus. Refer to the TECH menu’s 05 SETUP PIN menu item to set or change the PIN number.

Info: In any SETUP menu that contains a range of settings, if the ﬁ rst

and last settings are equal (set to the same value) the function will be disabled, even if selected/enabled from the CTRL menu.

to adjust the power level to determine when the inverter leaves Search mode. If this feature is not needed, select Search=OFF. When search is turned off, the inverter continuously provides full AC voltage to the loads.

Default setting: 5 Watts Range: OFF, 5-50 Watts

Info: When the Search Watts feature is active, “Searching” ap-

pears on the top line of the LCD display and the green INV LED will slowly ﬂ ash.

What is the Search Watts feature? This feature is used to help save

battery power by reducing the inverter’s output to search pulses when there is no detectable load. If a load greater than the wattage level setting turns on while the inverter is ‘searching’, the inverter will start ‘inverting’ to provide full voltage on its output.

Page 30

3.0 Setup

Should I use the Search Watts feature? If the inverter can spend a great

deal of time searching (to reduce the power drain on your batteries) and you can tolerate small loads (less than 5 watts) being off, then the Search Watts feature should be used. However, if some small loads (i.e., digital clocks, satellite receivers, answering machines, etc.,) are required to be on, then this feature should be turned off (Search = OFF).

Where should I set Search Watts? The Search Watts setting should be

adjusted to the same power level (or next lower setting) of the smallest load that you plan to run. If you don’t know the wattage of the smallest load, turn the switch for the load on and decrease the Search Watts setting until the load comes on and stays on.

Info: Even though the Search Watts feature is on, some connected

equipment—even if they are off—may draw enough current to keep the inverter in the Inverting mode (i.e., not “Searching”).

• 02B LBCO Setting – The LBCO setting (Low Battery Cut Out) sets

the DC voltage level that turns off the inverter. This helps protect the batteries from over-discharge damage. If the battery voltage drops below the LBCO set-point continuously for more than one minute, the FAULT LED will come on, the inverter will turn off, and the display will show a “Low Battery” status. If the battery voltage falls below 8.5 volts (12-volt models), 17.0 volts (24-volt models), or 34.0 volts (48-volt models) the FAULT LED and Low Battery status indications will be immediate.

Default settings: LBCO = 10.0 VDC (12v), 20.0 VDC (24v) or 40.0

VDC (48v)

Ranges: 9.0-12.2 VDC (12v), 18.0-24.4 VDC (24v), 36.0-48.8 VDC (48v)

Info: The inverter automatically begins inverting when the DC volt-

age increases to ≥ 12.5 VDC (12-volt models), ≥ 25.0 VDC (24-volt models), or ≥ 50.0 VDC (48-volt models). If AC power is available and connected to the inverter’s input, the inverter automatically clears the low battery fault, passes the input AC power to the output, and begins charging the batteries.

Where should I set the LBCO setting? If your goal is not to discharge

your batteries more than 20%*, then set the LBCO setting from 11.5 - 12.2 VDC (12-volt models), 23.0 - 24.4 VDC (24-volt models), or 46.0 - 48.8 VDC (48-volt models). In some applications, such as those installed in an off-grid home or when doing a lot of RV dry-camping, you may want to cycle down to 50%* by setting the LBCO from 10.0 to 11.4 VDC (12-volt models), 20.0 -

22.8 VDC (24-volt models) or 40.0 to 45.6 VDC (48-volt models). In extreme circumstances, you have the ability to discharge the batteries to 80%* by setting the LBCO to 9.0 or 9.5 VDC (12-volt models), 18.0 - 19.0 VDC (24volt models), or 36.0 or 38.0 VDC (48-volt models) before recharging.

* These are rough estimates. For accurate battery monitoring, a battery monitor such as Magnum’s ME-BMK/ME-BMK-NS is required.

Info: The higher the LBCO setting, the less the inverter discharges

the batteries; which allows the batteries to have a longer life. The down side to a higher LBCO setting is that you need to charge more often to prevent the inverter from shutting off in Fault mode.

Info: If there is an ME-AGS-N installed, it should be set to start

at ≥1.0 volts higher than the LBCO setting—this is to prevent the inverter from shutting down before the generator comes on.

**IMPORTANT**

1. To use the AC In Control features (AC In-Time, AC In-VDC, and AC In- SOC), the AC source must always be connected and available for use

at the inverter’s AC input—such as utility power. There is no beneﬁ t from using the AC In feature if the AC source is from a generator, because the generator power may not be available when the AC In feature becomes activated.

2. When an AC In feature (AC In–Time, AC In–VOC, AC In–SOC) is selected, that feature is active whether or not there is any AC power on the inverter’s input. If no AC power is available, the inverter continues in Inverter mode. However, if AC power becomes available on the inverter’s input after the connect setting (Time, VDC, or SOC) has been reached, the inverter continues to allow the incoming AC power to be connected and used until the disconnect setting is reached.

3. When using a dual source inverter/charger such as the MSH4024RE, the AC In features only work with the GRID IN (AC1) input.

• 02C AC In-Time – This feature allows you to connect to the local power

utility at a predetermined time of day. When the current time falls within the set times, the inverter/charger connects to the AC that is connected to the AC input terminals. Once outside the set times, the inverter/charger disconnects from the AC source.

Set Connect – These settings determine what time each day the inverter/

charger allows the incoming AC to connect and transfer the loads from the inverter’s battery power to the utility grid.

Default setting: 6:00A Range: 12:00AM-11:59PM

Set Disconnect – These settings determine what time each day the

inverter/charger disconnects any incoming AC that is connected, and resumes powering the AC loads from the inverter’s battery power.

Default setting: 6:00P Range: 12:00AM-11:59PM

What is the AC In-Time feature? This feature allows the incoming AC

to connect to the inverter/charger and charge the batteries only during the time of day as set in the 02C AC In-Time menu item. Even if AC is present on the AC input terminals of the inverter/charger, it can only connect during those times previously set

your local utility company offers peak rate savings (or “time of day billing”). The utility company offers the peak rate savings with a lower rate per kWh (kilo Watt hour)—usually available at night when there is less demand on

local utility grid. The AC In-Time feature may save you money by only

the connecting to the utility when rates are the least expensive.

Where should I set AC In-Time? Check with your local utility company or

installer and see if they offer lower rates at particular times of the day. If a lower rate is offered, try setting your connect/disconnect times to coincide with the utility companies lower rates to save you money.

Example: Your standard rate on your power bill is $.10 kWh. Your utility

company offers $.08 kWh between 12:00 AM and 7:00 AM. Set your connect time to 12:00 AM and your disconnect time to 7:00 AM to coincide with the utility company’s lower rates in order to save money when using utility power to charge the batteries.

. The most common use of AC In-Time is when

Page 32

• 02D AC In-VDC – The AC In-VDC settings determine when the inverter/

charger automatically connects and disconnects the incoming utility power based on the inverter’s battery voltage.

Set Connect Volts – This setting determines at what DC voltage the

inverter/charger connects to incoming AC and transfers the loads from the inverter battery power to the utility grid. The transfer occurs only if the battery voltage remains below this setting for 10 seconds.

Default settings: 11.0 VDC (12v), 22.0 VDC (24v), or 44.0 VDC (48v) Ranges: 9.0-16.0 VDC (12v), 18.0-32.0 VDC (24v), 36.0-64.0 VDC (48v) Set Disconnect Volts – This setting determines at what DC voltage the

inverter/charger disconnects from incoming AC and resumes powering the AC loads from the inverter’s battery power.

Default settings: 14.1 VDC (12v), 28.2 VDC (24v), or 56.4 VDC (48v) Ranges: 9.0-16.0 VDC (12v), 18.0-32.0 VDC (24v), 36.0-64.0 VDC (48v)

Info: These settings are not temperature compensated.

Info: If you have a ME-BMK battery monitor, use the AC In-SOC

feature instead. The AC In-SOC feature takes temperature compensation into account and is a more accurate way to identify when your battery is discharged/charged—to determine when to transfer to/from utility power.

What is the AC In-VDC feature? This feature allows the inverter system to

automatically switch between utility connected and standalone battery operation—based on the VDC voltage (i.e., battery) to the inverter. When using this feature, the inverter loads are powered from the battery and another energy source such as solar, wind, and/or hydro. In the event the energy source cannot deliver enough power, and the battery voltage drops to the Set Connect Volts setting, the inverter connects to the utility to continue powering the loads connected to the inverter’s output and to charge the battery. Once the energy source can again deliver enough power to raise the battery voltage to the Set Disconnect Volts setting, the inverter disconnects from the utility and again powers the inverter loads from the battery.

Where should I set AC In-VDC? Check with your battery manufacturer to

determine the correct settings for your batteries. Typically, battery manufacturers do not recommend discharging the batteries below 50%, which when related to a voltage setting is approximately 12.0-12.2 VDC, 24.0-24.4 VDC and 48-48.8 VDC for 12, 24 and 48-volt batteries respectively. In order to protect the batteries from over-discharging, set the connect voltage setting to 12.2 VDC, 24.4 VDC, or 48.8 VDC respectively. Set the disconnect voltage setting higher than the absorb voltage setting in order to reduce cycling of the system. A setting higher than the absorb voltage requires the energy source (solar, wind, etc.) to raise the DC voltage above the charger settings. This ensures the battery gets at least an 80-85% charge (preferably 100%) before the AC is disconnected and the inverter resumes powering from the batteries.

• 02E AC In-SOC

automatically connects and disconnects the incoming utility power based on the State of Charge (SOC) of the inverter battery bank.

Note: This feature requires the ME-BMK battery monitor to be installed

to provide SOC values to the inverter/charger.

– This setting determines when the inverter/charger

Page 33

3.0 Setup

Set Connect SOC – This setting determines at what battery SOC per-

centage the inverter/charger will connect to incoming AC and transfer the loads from the inverter battery power to the utility grid.

Default setting: 50% SOC Range: 20-98% Set Disconnect SOC – This setting determines at what battery SOC

percentage the inverter/charger will disconnect from incoming AC and resume powering the AC loads from the inverter’s battery power.

Default setting: 100% SOC Range: 21-100%

Info: The transfer to/from incoming AC occurs immediately when

the Connect SOC or Disconnect SOC setting is reached.

Info: The AC In-SOC feature requires a valid SOC number (0-

100%). If a valid number is not displayed under the METER/04 BMK Meters/04B SOC menu, then the charger will immediately go to Float Charge once the Bulk Charge stage is ﬁ nished.

What is the AC In-SOC feature? This feature allows the inverter/charger

system to automatically switch between utility connected and standalone battery operation based on the inverter’s battery SOC that is provided by the ME-BMK battery monitor. When using this feature, the inverter loads are normally powered from the battery and a solar array (or other energy source such as wind, and/or hydro). In the event the solar array cannot deliver enough power and the battery’s SOC drops to the Set Connect SOC setting, the inverter connects to the utility to continue powering the loads connected to the inverters output and to charge the battery. Once the solar array can again deliver enough power to charge the battery to the Set Disconnect SOC setting, the inverter disconnects from the utility and again powers the inverter loads from the battery.

Where should I set AC In-SOC? Check with your battery manufacturer to

determine the correct settings for your batteries. Typically, manufacturers do not recommend discharging the batteries below 50% to maintain the life of the battery. Set the Disconnect SOC value to get at least an 80-85% charge (preferably 100%) before the AC is disconnected and the inverter resumes powering from the batteries.

Info: When using AC In-SOC, ensure the SETUP/03E Absorption

Done SOC setting is higher than the Set Disconnect SOC setting,

or the inverter may not disconnect from the incoming AC.

Notes on using the AC In feature based on VDC or SOC:

1. The AC In-VDC or AC In-SOC feature allows you to optimize the use of the another energy source (i.e., solar, wind, and/or hydro) and only allow the use of the utility power when the energy source is not able to keep up with the load demands under normal conditions (i.e., cloudy day).

2. The energy source should be sized to meet the daily power requirements of the loads being operated under normal conditions. Otherwise, the inverter would be connected to utility power most of the time, resulting in excessive energy consumption from the utility.

3. The inverter system should not be conﬁ gured for use in a utility back- up scenario, otherwise the battery may be in a highly discharged state when grid power goes down—preventing the critical loads from running during a power outage.

• 02F Power Up Always – Allows the inverter to power up and provide

AC power automatically once DC voltage is connected to the inverter.

Default setting: OFF Range: OFF, ON

What is the Power Up Always feature? Normally, when DC power is con-

nected to the inverter, the user is required to press the power button—on the inverter or remote—to turn the inverter on. When the Power Up Always feature is activated by selecting “ON”, the inverter is automatically turned on and starts searching or inverting—depending on the SETUP:02 Invert Setup/02A Search Watts setting. Once the inverter has connected to DC power and is automatically turned on, the power button—on the inverter or remote—can be used to turn the inverter on or off.

Why use the Power Up Always feature? Some customers are familiar with

Uninterruptable Power Supplies (UPS) that power-up automatically when DC power is connected. The Power Up Always feature can be used by customers that want to obtain the same automatic power-up feature with which they are familiar.

SETUP: 03 Charger Setup

• 03A AC Input Amps – This selection ensures that the combined current

draw from the charger and the AC loads does not exceed the maximum input current that is available from the incoming AC power. Whenever the utility or generator is connected to the inverter’s input, the current used to power the AC loads and to charge the batteries is monitored. When the total current used to power the AC loads and charge the batteries begins to approach the AC Input Amps setting, the current used for charging the batteries is automatically reduced. This ensures the AC loads have all the available current from the incoming AC power when needed.

Setting for all models except MSH4024RE:

Set AC Input Amps – This setting determines the level in AC amps

at which the inverter/charger begins to back off the battery charger to reduce the load on the incoming utility/generator power and continue powering the inverter loads.

Default setting: 30 Amps Ranges: 5-60 Amps

Settings for MSH4024RE:

Info: The MSH4024RE inverter/charger has two independent AC

source inputs (AC1/GRID, AC2/GEN) with independent AC input amps settings for each. The Set AC1 Input Amps and Set AC2 Input Amps menus only display if the remote is connected to a dual input source inverter/charger.

Set AC1 Input Amps – This setting determines the level in AC amps

at which the MSH4024RE inverter/charger begins to back off the battery charger to reduce the load on the incoming utility/grid power (that is connected to the AC1 input) and continue powering the inverter loads. This setting also determines when the MSH4024RE inverter/charger

Page 35

3.0 Setup

begins to operate in parallel with the incoming utility power to support

the inverter loads (i.e., Load Support Mode¹). Typically, set to the size

of the AC circuit breaker that feeds the AC1 input.

Default setting: 30 Amps Range: 5-60 Amps Set AC2 Input Amps – This setting determines the AC amps lev

which the MSH4024RE inverter/charger begins to back off the battery charger to reduce the load on the incoming generator power (that is connected to the AC2 input) in order to continue powering the inverter loads. This setting also determines when the MSH4024RE begins to operate in parallel with the incoming generator power to support the

inverter loads (i.e., Load Support Mode¹). Typically, this is set to the size

of the generator’s circuit breaker that feeds the inverter AC2 input, or to the maximum output amperage ability of the generator.

Default setting: 20 Amps Range: 5-60 Amps

Where should I set AC Input Amps? This setting controls the input current

differently depending on the inverter/charger model and the AC input wiring conﬁ guration. Set as described below for your particular model:

ME, MS, and RD Series: These models have two inputs (HOT IN 1 and HOT

IN 2), but the current is only monitored on HOT IN 1. On these models— when wired as a dual-in conﬁ guration or as a single-in conﬁ guration with only the HOT IN 1 connected—the AC Input Amps setting should be set to the size of the AC circuit breaker that feeds the HOT IN 1 input. On these models, when wired as a single-in conﬁ guration with HOT IN 1 and HOT IN 2 jumped together, set the AC Input Amps setting to half (x½) the input breaker size—as ½ the current will pass through HOT IN 1 and the other ½ through HOT IN 2 simultaneously.

MS-AE and MS-PAE Series: These models have two inputs (HOT IN 1

and HOT IN 2), with the current monitored on each input at the same time. On these models, since the input is from a single AC source, both of the input currents are added together and divided in half to determine the AC Input Amps setting. Whether the input circuit breaker is a dual-pole (120/240 VAC input) or a single-pole (120 VAC only), set the AC Input Amps setting to the value of only one of the breaker poles (i.e. 30A dualpole = 30A setting, 30A single-pole = 30A setting).

MS-E, MS-PE, MSH-RE and MSH-M Series: These models may have

one (AC1) or two (AC2) inputs, with the current monitored on each input separately. On these models, set the AC Input Amps setting to match the input AC circuit breaker size.

MM, MM-AE and MMS Series (and any export version of these models): These models do not monitor current on the input, therefore

cannot beneﬁ t from the AC Input Amps setting or feature. On these models, the AC Input Amps setting may be displayed and allow selection/ adjustment, but will not do anything to reduce the battery charger current.

Note¹: The MS Hybrid (MSH) Series inverter/chargers have Load Support

Mode, which allows the inverter power to operate in parallel with the incoming AC power (Grid or Gen). This feature uses additional power from the inverter’s battery to run loads greater than what the incoming AC power can run alone, and prioritizes the power of any external DC source (i.e., solar, wind, etc.) over the incoming AC power to run inverter loads. For more information, see the Load Support Mode section in the MSH Owner’s Manual.

3.0 Setup

Info: If you are supplying two AC sources (utility and generator) to

the inverter’s single input through an AC transfer switch, adjust the AC Input Amps setting to the smaller AC circuit breaker size of the

two AC sources. Info: The AC Input Amps setting is dependent on the stability of the

AC source. If using a generator, factors such as altitude and output voltage regulation may require a lower setting than the generator’s circuit breaker size. For best performance, lower the AC Input Amps setting to 1/3 of the generator’s rated capacity, and then while the generator is heavily loaded, gradually increase the setting as high as possible, but ensure the voltage level stays above the 03D VAC Dropout setting.

CAUTION: Unless you have an MS Hybrid Series inverter/charger—

which provides the Load Support feature—the AC Input Amps setting does not limit the current to the inverter loads. If the current from the loads on the output of the inverter are greater than the circuit breaker rating on the incoming AC source, you may experience nuisance tripping on this breaker.

• 03B Battery Type – Used to select the battery type, which determines

the battery charge proﬁ proper charge voltage. The ﬁ xed voltage selections are GEL (for Gel batteries), Flooded (for liquid lead acid batteries), AGM 1 (for Lifeline AGM batteries), and AGM 2 (for East Penn/Deka/Discover/Trojan AGM batteries). The Custom selection allows the Float, Absorb, and

Equalization charge v

Table 3-2 to determine the speciﬁ c charge voltage based on the battery type selected.

Default setting: Battery Type = Flooded Range: GEL, Flooded, AGM1, AGM2, Custom

le and ensures the batteries are receiving the

oltage settings to be individually adjusted. See

Info: The voltage settings shown in Table 3-2 are based on the Bat-

tery Temperature Sensor (BTS) at a temperature of 77° F (25° C), or not connected. If the BTS is connected, the actual charge voltage will increase if the temperature around the BTS is below 77° F (25° C), and decrease if higher than 77° F (25° C). This ensures the batteries receive the correct charge voltage regardless of temperature.

• 03C Max Charge Rate – Sets the maximum charge rate allowed

to charge the batteries during Bulk, Absorption, Float, and Equalize charging. Selections are Max Charge = 0% up to 100%. The Max Charge = 0% setting is available to help minimize charging while continuing to allow pass-thru power. The rest of the selections are provided to limit the charge rate to the battery bank, which helps prevent battery overheating caused by charging at too high a charge rate.

The Max Charge Rate selections are provided as a percentage of the inverter/charger’s maximum charging capability. Refer to the label on the side of the inverter (or owner’s manual) to determine the inverter’s maximum charge rate. Once you ﬁ nd this max charge rate, determine the percentage needed to limit the charge rate to your battery bank.

Default setting: Max Charge = 100% Range: 0-100%

Page 37

3.0 Setup

Example: The maximum charge r

ate of your inverter/charger is 120 amps and you need to limit the charge rate to 72 amps. Choose the Max Charge = 60% setting (72 amps = 60% of 120 amps).

Info: If the Maximum Charge Rate setting is set to 0%, the topol-

ogy of the Magnum inverter (when connected to an AC source) will override the 0% setting and start charging if the battery voltage is: <12 VDC (12-volt models), <22 VDC (24-volt models), or <44 VDC (48-volt models).

How do I determine where to set my Maximum Charge Rate? The maximum charge rate is generally set to a C/5* rate (C = the total amp-

hour capacity of the battery bank – using the 20-hour AH rate). The C/5 rate is usually used when the objective is to charge the batteries as quickly as possible (i.e., 400 AH ÷ 5 = 80 amp maximum charge rate). A lower rate such as C/20* is used when the batteries need to be charged as slow as possible.

* C/5 or C/20 rate – charge rates are commonly expressed as a ratio of the total

amp-hour (AH) capacity of the battery bank. For example, with a 400 AH battery bank (C = 400), the C/5 charge rate is 80 A (400/5 = 80 A).

CAUTION: The C/5 or C/20 charge rate settings are guidelines.

They are not requirements on how you should set your battery charge rate. For speciﬁ c charge rate requirements, refer to your battery manufacturer.

3.0 Setup

Info: If multiple inverter/chargers are used on a single battery bank,

you must ensure that the total charge rate from all inverter/chargers is limited to the maximum charge rate needed for your battery bank. The Max Charge Rate setting only limits the charging on each inverter/charger individually, not on all inverter/chargers.

• 03D VAC Dropout – Selects the minimum AC voltage that must be

present on the input before the inverter/charger switches from Inverter mode to Standby mode. This setting also determines the minimum AC voltage threshold where the charger disengages and the inverter (when turned on) resumes powering the AC loads from the inverter’s battery power. This protects AC loads from utility outages.

Example: If the VAC Dropout setting is 60, then the AC input voltage must

be above 60 volts before the inverter connects and switches from Inverter mode to Standby mode. Once the AC is connected, the AC voltage must drop below 60 VAC to switch back to Inverter mode.

Settings for all models except MSH4024RE:

Set VAC Dropout – This setting determines at what AC voltage—from

the HOT IN 1 to NEUT IN 1 terminals—the inverter/charger will connect to or disengage from the incoming AC.

Default setting: 80 VAC (150 VAC for export models) Range: 60-100 VAC, UPS Mode (110-190 VAC, UPS Mode for export

models)

Settings for MSH4024RE:

Info: The MSH4024RE inverter/charger has two independent AC

source inputs (AC1/GRID and AC2/GEN) with independent VAC dropout settings for each input. The Set VAC Dropout AC1 and Set VAC Dropout AC2 menus only display if the remote is connected to a dual input source inverter/charger.

Set VAC Dropout AC1 – This setting determines what AC voltage—from

the MSH4024RE inverter/charger’s AC1 to NEUTRAL terminals—the inverter/charger will connect to or disengage from the incoming AC.

Default setting: 80 VAC Range: 60-100 VAC, UPS Mode Set VAC Dropout AC2 – This setting determines what AC voltage—from

the MSH4024RE inverter/charger’s AC2 to NEUTRAL terminals—the inverter/charger will connect to or disengage from the incoming AC.

Default setting: 75 VAC Range: 60-100 VAC

Where do I set my VAC Dropout? It depends on the application and what

you are using as the AC source. The settings not only look at the incoming voltage level to determine when to transfer, but also determine how quickly the charger disconnects and starts inverting based of the ﬂ uctuations of the incoming AC voltage.

Dropout = 60 VAC to 100VAC (Export inverter models: Dropout = 110 VAC to 190 VAC) – Use a VAC dropout setting from 60 VAC to 100

VAC (export models use a dropout from 110 VAC to 190 VAC) when the AC source may have ﬂ uctuations in RMS voltage. These settings attempt to prevent the charger from disengaging unnecessarily due to

Page 39

3.0 Setup

poor quality voltage, and are highly recommended if using a generator for charging. The transfer time from Standby mode to Inverter mode is >16 milliseconds when using these settings.

Dropout = UPS Mode – Use the UPS Mode setting when the AC source

is well regulated above 105 VAC (200 VAC for export inverter models), and the inverter loads are sensitive to voltage ﬂ uctuations. This setting is intolerant of voltage ﬂ uctuations and will provide a quick transfer. The transfer time from Standby mode to Inverter mode is ≤16 milliseconds when using this setting. Do not use this setting if using a generator as your AC source.

Info: If you get nuisance AC disconnects, either change the setting

to 100 VAC or less (export models 190 VAC or less), or obtain a better voltage-regulated AC source.

• 03E Absorb Done (Time, Amps, SOC) – This setting identiﬁ es whether

time, amps, or SOC are used to determine when the second stage of battery charging (Absorption stage) is ﬁ nished. The charge cycle transi- tions to the ﬁ nal charge stage (see 03G Final Charge Stage) afterwards. Absorption is the second stage of the charge process that attempts to fully charge the batteries.

Info: If the Absorb stage is short or terminated, the batteries may

not receive a full charge. In contrast, if the Absorb stage is too long the batteries may be overcharged. Either scenario may lead to damage to the batteries. Contact your battery manufacturer to ensure the best charge settings are used for your type of batteries.

Set Absorb Done Time – Set Absorb Done Time is used when a speciﬁ c

time is determined to be the best solution for ending the Absorption stage. When using time, the battery bank size will typically determine the length of the Absorb Done Time setting. The larger the battery bank, the longer the absorb time needed to ensure a full charge to the batteries. Taking speciﬁ c gravity readings of the batteries and adjusting the absorb time may be needed in order to obtain the appropriate absorb time for your battery type and battery bank size. See Table 3-3 to help select the Absorb Done Time setting based on the amp-hr capacity of your battery bank.

Default setting: Absorb Done Time = 2.0 Hrs Range: 0.1-25.5 Hrs

Info: The Absorb Done Time setting’s range is dependent on the

software revision of your inverter. With inverters having a revision

5.0 or greater, your available range is 0.5 to 25.5 hours. However, if your inverter revision is less than 5.0, even though you can adjust the setting from 0.5 to 25.5 hours, the available range is only from 1.0 to 6.5 hours. Any setting less than 1.0 hour or greater than 6.5 hours is not recognized, and will cause the charger to revert to the default setting of 2.0 hours. See Section 3.2 for more information.

Set Absorb Done (Amps) – This setting is used when the DC amperage

supplied to the batteries (i.e., return amps) is used to determine when the batteries are fully charged. During Absorb Charge mode, the return amps from the charger slowly decrease. When this current decreases below the Absorb Done Amps setting, the charger transfers from the Absorb charge cycle to the ﬁ nal charge stage (see 03G Final Charge Stage).

Most battery manufacturers use a speciﬁ c formula to determine the return amps that indicate a full charge for their particular type of battery. The formula used by most manufacturers to absorb the batteries is C/20, where C=Battery Bank’s Total Amp Hours. Basically, they take approximately 5% of the total battery bank size, and consider the battery totally charged when the charger’s return amps drops to this level. Continuing to charge past this level may possibly overcharge the batteries. Check with your battery manufacturer to ﬁ nd out what the correct return amp settings are for your batteries.

Default setting: Absorb Done Amps = 20 ADC Range: 0-150 ADC

Battery

AmpHrs

Capacity

Absorb Time

Info: Setting the Absorb Done Amps value to 0 (zero) will keep the

charger in the Absorb charge mode until the 03F Max Charge Time setting is reached (if no BMK installed).

Info: If DC loads are connected directly to the batteries, it is not

recommended that you use the Absorb Done Amps setting. DC loads cause the charger to increase amperage delivered to the battery bank in order to charge the batteries, plus run the DC loads. This scenario could result in overcharging the batteries since the return amps reading will be skewed by the DC loads.

Info: It is highly suggested that you install a battery monitor

if the Absorb Done Amps setting is used. If a battery monitor is not installed, the Absorb Done Amps setting relies on the METER menu’s 01B DC Amps value to determine when to transfer out of the Absorb Charge mode. When a battery monitor kit (ME-BMK/ ME-BMK-NS) is installed, the Absorb Done Amps setting relies on the METER menu’s 04C DC Amps–BMK value to determine when to transfer out of the Absorb Charge mode. This is the most accurate DC amperage measurement. The DC amps reading from the battery monitor is accurate to +/- .1 ADC.

Page 41

3.0 Setup

Set Absorb Done (SOC) – This setting can be used if a battery moni-

tor kit is installed, and you want to use the SOC (State of Charge) of the battery bank to determine when the batteries are fully charged. The SOC is the best way to determine when the batteries are fully charged. The SOC also is helpful because any DC loads or other charge sources connected to the battery bank will not affect the SOC reading, and the batteries will always receive a full charge.

Default setting: Absorb Done SOC = 100% Range: 50-100%

Info: A ME-BMK is required in order to use the Absorb Done SOC

setting. If the Absorb Done SOC setting is selected and there is no ME-BMK installed in the system, or if a valid SOC number is not displayed under the METER/04 BMK Meters/04B SOC menu (i.e., Think’n, No Comm, Pwr-up Fault are not valid SOC numbers), then the charger will immediately go to the Float Charge stage once the Bulk Charge stage is ﬁ nished.

Info: If the Absorb Done SOC setting is used when charging from

a generator source, then it is recommended that a setting of less than 100% be used (usually around 90% is acceptable). This lower setting is used because running the generator past the 90% setting is sometimes considered an inefﬁ cient use of fuel. If a setting lower than 100% is used, then at least once a week the batteries should be charged to 100%, to make sure damage is not done to the batteries by not bringing them to a full charge state.

• 03F Max Charge Time – The Max Charge Time setting is a safety fea-

ture that ensures abnormal conditions will not cause the charger to hold batteries at a high voltage for a prolonged period of time. This menu sets a maximum time the charger is allowed to operate in either the Bulk or Absorption Charge mode. If the charger reaches the maximum charge time setting, it will transition to the ﬁ nal charge stage as set in the SETUP button’s 03G Final Charge Stage.

Default setting: Max Charge Time = 12.0 Hrs Range: 0.0-25.5 Hrs

Where should I set my Max Charge Time? In order to ensure a complete

charge cycle is accomplished, adjust the Max Charge Time setting to a time period that will normally be longer than the settings in the following SETUP menu items: 03E Absorb Done Time, 03E Absorb Done Amps, and 03E Absorb Done SOC. The Max Charge Time setting has priority over these menus and will stop the charge cycle once that setting is satisﬁ ed.

Example: The Max Charge Time setting is six hours, but the Absorb Done

Time setting is eight hours. The charge cycle will stop after six hours as per

the Max Charge Time setting, and not ﬁ nish the Absorb Done Time setting of eight hours.

Page 42

3.0 Setup

• 03G Final Charge Stage – The Final Charge Stage setting is the stage to

which the charger will transition after the absorption stage has ﬁ nished— as set in the 03E Absorb Done menu.

Default setting: Set Final Charge Stage = Multi Range: Multi, Float, Silent

Info: The Final Charge Stage menu item is only used when Multi-

Stage is selected in the 02 CHG Control menu.

Set Final Charge Stage = Multi – The Multi setting (which is short

for “Multi-Stage”), transitions from the Absorption stage to Float. Once in the Float stage for four hours with no DC load on the batteries, the charger will enter the Full Charge stage (i.e., Battery Saver mode). In Full Charge mode, the charger automatically stops charging but is still on and actively monitoring the battery voltage. The charger will remain in the Full Charge stage until the battery voltage drops below 12.7 VDC for 12-volt batteries, 25.4 VDC for 24-volt batteries, and 50.8 VDC for 48-volt batteries—at which time it will return to the Float stage. These battery voltages are the fully charged voltages of a battery at rest. The charger will continue to cycle between Float and Full Charge as long as incoming AC is available.

Info: When Multi is selected and the charger goes to Full Charge

mode, if another charge source (such as PV or wind) is charging the batteries above the fully charged voltage, the charger will remain in the Full Charge stage.

Why should I use Multi? Multi is the most commonly used charge

mode. It is suitable for most applications and will assure a full charge to the batteries, without overcharging. If there is another alternate charge source charging the batteries, such as PV, wind or hydro, then Multi mode will use the inverter/charger to complete a full charge. The inverter/ charger will transition to Full Charge mode and the alternate charge source will then maintain the battery voltage. If the alternate source is unable to maintain the voltage, the charger will enter Float mode for another four hour period. The Full Charge feature in the Multi mode also helps reduce water consumption in ﬂ ooded batteries when they are left in the charge mode for extended periods, such as in a backup power application.

Set Final Charge Stage = Float – The Float stage is a maintenance

charge mode that maintains a constant voltage—while delivering up to the maximum rated current of the charger in order to power any DC loads connected to the batteries. Most 3-stage chargers ﬁ nish the charge mode in Float and remain in Float as long as an AC source is available on the input of the charger. The ﬂ oat voltage is determined by the battery type selected in the 03B Battery Type menu. Unlike Multi mode, in Float mode there is no Full Charge feature.

Why should I use the Float Charge Stage? Float mode is typically used

when the charger is the only charge source connected to the batteries. This mode will maintain the batteries at the ﬂ oat voltage. If using ﬂ ooded batteries and the charger is in ﬂ oat for an extended period, the water level should be checked every two to three weeks for proper levels.

Page 43

3.0 Setup

Set Final Charge Stage = Silent – Silent mode stops charging once it

transitions from Absorb mode to ‘Silent’. Once the charger enters Silent mode the battery voltage is continuously monitored. If the batteries fall to the Set DC Volts to Rebulk value, the charger restarts the Bulk Charge mode and then transitions to Absorb Charge mode. After the Absorb Charge mode, the charger again transitions to Silent mode. This silent to rebulk to absorb and back to silent cycle will continue as long as it is required.

Set DC Volts to ReBulk – When Silent mode is selected, you must

also set the DC voltage set-point where the charger restarts the Bulk Charge mode. This setting should be at the lowest DC volts you want the batteries to fall before starting a new bulk charge. Typically, the lowest DC volts the batteries are allowed to fall is 12.0 to 12.2 VDC (12-volt systems), 24.0 to 24.4 VDC (24-volt systems), and 48.0 to 48.8 VDC (48-volt systems) respectively.

Default setting: Set DC Volts to ReBulk = 12.0 Ranges: 12.0-16.0 VDC (12v), 24.0-32.0 VDC (24v), 48.0-64.0 VDC (48v) Why should I use the Silent Stage? Silent mode is typically used when

an alternate charge source is available and able to fully charge or ﬁ nish the charge cycle after the Absorb stage. A major difference between Multi mode and Silent mode is that the Silent mode returns to Bulk mode instead of Float mode. In Silent mode you can also adjust the Rebulk set-point in order to allow the alternate charge source to provide more of the battery charging.

5.1.1 LED Indicators

There are four LED indicators on the front panel that light solid or blink to indicate the inverter/charger’s status. When the remote is ﬁ rst powered-up, all the LED’s come on as it goes through a self test (See Section 2.5 for info on the Self Test). Once the self test is complete and the clock is set, the LED’s and the LCD provide the operating status of the inverter/charger. See Section 5.3.5 for more information on the LED indicators.

5.1.2 LCD Display

The LCD display is used for setting up the system operation, as well as viewing the current operating status and fault conditions. This display has two lines of alphanumeric characters and features a backlight that can be set to turn off to conserve power. The top line provides the inverter/charger status, which is detailed in this section. The bottom line displays battery information when using the METER menu, displays system troubleshooting information when using the TECH menu, and displays menu items that can be conﬁ gured for your speciﬁ c system operation when using the SETUP menu. This display automatically powers-up with the current system status on the top line and the home screen (detailing the inverter’s DC voltage and current as shown in Figure 5-1) on the bottom line.

charger, and the ME-AGS-N and ME-BMK/ME-BMK-NS (if connected). See Section 3.3.3 for more detailed information.

• SETUP – This button allows the remote, the inverter/charger, and

any connected accessory to be conﬁ gured to your speciﬁ c system preferences. See Section 3.3.4 for more detailed information.

• TECH – This button allows you to access menu selections that can help

service personnel with troubleshooting, and also allows the factory default settings for the inverter/charger and any connected accessory to be restored. See Section 3.3.5 for more detailed information.

5.1.5 Rotary SELECT Knob

The rotary SELECT knob is similar to a car dash radio knob, and is used to view and select various menu items and settings displayed on the LCD screen. Turn the rotary knob clockwise and counterclockwise to view the different menu items and available settings. Press the SELECT knob to select/enter a menu item or to save a setting once it is displayed on the LCD screen. Press and hold the SELECT knob for 10 seconds to refresh the LCD display.

Info: All adjustable inverter/charger settings in the ME-ARC (except

for 01B Contrast, 01C Backlight, and 03 GEN Control—which revert back to default) are saved in non-volatile memory. These adjustable settings are preserved until changed, even if an inverter reset is performed or power to the remote or inverter is removed.

CAUTION: An accessory that is networked to the inverter may

have adjustable settings that revert back to default if all power to the inverter is lost. Refer to the owner’s manual for the particular accessory to determine if any setting is affected.

Page 57

5.0 Operation

5.2 Operating the Inverter/Charger

5.2.1 Inverter Mode

Turning the inverter on: Press the ON/OFF INVERTER button to activate the

inverter function. The inverter will either be actively “inverting” by using power from the batteries to power the AC loads; or, the inverter will be “searching” for a load by using very little power from the batteries, if in Searching mode. The green INV LED is on when the inverter is actively inverting, and the green INV LED ﬂ ashes while searching.

Turning the inverter off: While the inverter is actively inverting or search-

ing, press the ON/OFF INVERTER button to switch the inverter function off. This turns the green INV LED off.

Inverter Standby – The inverter is in Inverter Standby mode when it is

enabled (green INV LED is on) but not actively providing power from the batteries to the inverter loads. During Inverter Standby mode, the loads connected to the inverter are powered by the external AC power; however, if a blackout or brownout condition occurs, the inverter senses these conditions and starts inverting to power the inverter’s AC loads.

CAUTION: If you have critical loads and are in Inverter Standby,

do not press the ON/OFF INVERTER button to turn the inverter function off. If the green INV LED is off, inverter power will NOT be available to run your critical loads if the external AC power is interrupted.

5.2.2 Charger Mode

Turning the charger on: The Charge mode is automatically activated and

begins when acceptable AC power (utility or generator) is connected to the input of the inverter. When in Charge mode, the display may show: Charging,

Bulk Charging, Absorb Charging, Float Charging, Full Charge, Silent, Charger Standby, Force Float, Equalizing, Load Support VDC, and Load Support AAC.

Charger Standby – While the charger is actively charging, press the ON/OFF

CHARGER button to switch the charger to Charger Standby. While in Charger Standby, the incoming AC is still available on the inverter’s output, but the charger is not allowed to charge. The LCD displays “Charger Standby” and the CHG LED ﬂ ashes.

Info: To resume charging, momentarily press the ON/OFF CHARGER but-

ton or disconnect/reconnect AC power to the inverter’s input.

Equalize Charging – Equalizing is a “controlled overcharge” performed after

the batteries have been fully charged. It helps to mix the battery electrolyte (to reverse the buildup of stratiﬁ cation) and to remove sulfates that may have built up on the plates. These conditions if left unchecked, will reduce the overall capacity of the battery. To enable the Equalization charge, see page 53.

WARNING: Do not perform an Equalization charge without read-

ing and following all safety precautions pertaining to charging/ equalization as noted in this manual and provided by the battery manufacturer, and any equalization information in the inverter owner’s manual.

5.3 System Status Messages

A status message may be an operational or fault message indicating the inverter/ charger’s current operating status. This section will cover the inverter/charger’s operating and fault modes, and the available status messages under each mode.

Use the displayed status message and the status LED’s on your ME-ARC remote (Figure 5-2) to determine the inverter/charger’s current operating status, and to help troubleshoot the system if a fault occurs.

There are three modes of operation for the inverter/charger:

• Inverter mode • Charger mode • Fault mode

Refer to the appropriate section to locate information on any particular status message.

Figure 5-2, System Status Screen (example)

5.3.1 Inverter Mode Status Messages

There are several Inverter mode messages. View the top line of the LCD display and the corresponding message in this section to determine and understand the particular Inverter mode.

• Inverting – The inverter is providing AC voltage on its output by

inverting power from the batteries.

• Inverter Standby – The inverter is on but not actively providing power.

However, the inverter remains active and an external AC power (utility or generator) is passing through the inverter to power the AC loads.

• No Inverter Comm – The remote is no longer receiving any

communication data via the Magnum Network.

Remedy: Reset the remote by disconnecting the remote commu-

nications cable from the inverter for ﬁ ve seconds, and then recon- nect (see Figure 2-2). If the fault continues, ﬁ rst check/replace the remote cable (4-wire telephone cable).

What if the cable is not the issue?

• Try another remote display

• Reconnect the remote from the Remote port to the Network port

• The inverter may need servicing

• Off – This message tells you that there is no AC available on the

inverter’s AC output. The inverter function is OFF and there is no utility or generator AC power sensed on its input.

• Searching – The inverter is in Search mode. This means the AC loads

on the inverter output are less than the SETUP menu’s 02A Search Watts setting. The Search mode function is used to reduce the inverter draw from the battery, and may be turned off at any time if you want full inverter output voltage available at all times (see 02 Invert Setup on page 23).

Page 59

5.0 Operation

5.3.2 Charger Mode Status Messages

When AC power (utility or generator) is connected to the inverter/charger, it begins to monitor the AC input for acceptable voltage. Once the AC input is accepted, the AC transfer relay (inside the inverter) closes and Charge mode begins. There are several Charger mode messages. View the top line of the LCD display and the corresponding message in this section to determine and understand the particular Charger mode.

Info: The AC input becomes acceptable once: a minimum 10-second

delay passes, the voltage is greater than the SETUP menu’s 03D VAC Dropout setting, and no AC In Control menu setting is actively preventing the AC from connecting.

• Absorb Charging – The Absorb charge state is the constant voltage

stage and begins when the absorb voltage is reached (determined by the SETUP menu’s 03B Battery Type setting) while Bulk charging. During this stage, the DC charging current decreases in order to maintain the absorb voltage setting. This charge stage continues until the 03E Absorb Done (Time, Amps, or SOC) or 03F Max Charge Time setting is reached.

• Bulk Charging – The battery charger is delivering maximum current

(determined by the SETUP menu’s 03C Max Charge Rate setting) to the batteries. The charger remains in Bulk charge until the absorb voltage (determined by the SETUP menu’s 03B Battery Type setting) or the 03F Max Charge Time setting is reached.

• Charger Standby – This indicates the charger has been disabled to

prevent further charging, but the AC power (from utility or generator) to the AC input is still available on the AC output. This display is shown when the ON/OFF CHARGER button is pressed while the AC power is passing through the inverter/charger.

Info: Press the ON/OFF CHARGER button to enable charging again.

When enabled, the charger will continue in the previous charge mode and the CHG (green) LED will come on solid.

• Charging – Once Charger mode has been enabled, the unit will

wait and display “Charging” to determine the charge routine. If the DC voltage is low (≤12.8 VDC/12-volt models, ≤25.6 VDC/24-volt models, or ≤51.2 VDC/48-volt models), the charger will initiate Bulk Charging. If the DC voltage is high (≥12.9 VDC/12-volt models, ≥25.6/24-volt models, or ≥51.2/48-volt models), the charger will skip the Bulk and Absorb charging stages and go directly to the ﬁ nal charge stage (Float or Silent).

• Equalizing – This display indicates that the battery charger is delivering

the equalize voltage to the batteries. See Table 3-1 to determine the equalize voltage for your battery type.

Equalize charging can be enabled by the ON/OFF CHARGER button if the SETUP menu’s 03B Battery Type setting allows. Equalization charging can only be enabled while the charger is in Float Charge or Full Charge mode. To turn on Equalize charging, ensure the LCD display reads “Float Charging” or “Full Charge”, then press and hold down the ON/OFF CHARGER button (about ﬁ ve seconds) until the LCD screen displays “Equalizing”.

The Equalize charge will continue for four hours and then automatically stop and return to Float charging. The Equalize charge can be manually stopped by pressing and holding down the ON/OFF CHARGER button (about ﬁ ve seconds) until the LCD screen displays “Float Charging”.

Page 60

5.0 Operation

During Equalize mode the batteries will begin gassing and bubbling vigorously, which consumes water. Ensure each cell has adequate distilled water levels prior to equalizing, and add water as needed after equalizing.

WARNING: Equalizing produces hydrogen and oxygen gas. To

avoid explosions, ensure the battery compartment has adequate ventilation in order to dissipate this gas.

CAUTION: Ensure your batteries can be equalized. Only do so if

permitted by your battery manufacturer or dealer. Performing an Equalization charge on batteries other than liquid lead acid or certain AGM types could permanently damage them. Contact your battery manufacturer for their recommendations.

CAUTION: Ensure the DC loads will not be damaged by the higher

voltage applied to the batteries during the equalize charge. If in doubt, disconnect the DC loads to prevent damage.

Info: Equalization charging is not available if GEL or AGM 2 is selected

from the Setup 03B Battery Type menu.

How often should I equalize? Some experts recommend that heavily

used batteries should be equalized periodically, ranging anywhere from once a month to once or twice per year. Other experts only recommend equalizing when the cells have a low speciﬁ c gravity, or when the difference between any individual cell has a speciﬁ c gravity reading greater than .015 after being fully charged. Contact your battery manufacturer for their recommendations.

How long should I equalize? While the batteries are gassing, monitor the

speciﬁ c gravity readings every hour. When the speciﬁ c gravity readings no longer increase, the Equalization charge is complete and should be stopped.

• Float Charging – At the end of the absorb charge time, the charger

reduces the charge voltage and tries to maintain the batteries at the Float charge voltage setting. This is determined by the SETUP menu’s 03B Battery Type setting as shown in Table 3-1.

Info: If the battery voltage falls ≤12.1 VDC (12-volt models),

≤24.2 VDC (24-volt models), or ≤48.4 VDC (48-volt models) the

unit will initiate Bulk charging.

• Force Float – This charge proﬁ le forces the charger to stay in the Float

mode as long as AC is present and the charger is active. Force Float is most often used when another source of charging (such as PV, wind, or hydro) is available to keep the batteries at the ﬂ oat voltage. If AC is disconnected and then reconnected, the charger will go directly to the Float mode and will not do a Bulk or Absorption charge cycle.

CAUTION: Using the Force Float mode may not fully charge the

Page 61

5.0 Operation

• Full Charge – This status indicates that you have entered the Battery

Saver™ mode. This mode maintains the batteries without overcharging, and prevents excessive loss of water in ﬂ ooded batteries or drying out of GEL/ AGM batteries. After four hours of Float charging, the charger will turn off and “Full Charge” displays (charger is now in Battery Saver™ mode). If the battery voltage drops to ≥12.6 (12-volt models), ≥25.2 (24-volt models) or ≥50.4 (48-volt models), the charger will automatically initiate another four hours of Float charging. This cycle helps to ensure the batteries are maintained and continues as long as AC power is continuously connected to the AC input. “Full Charge” only displays if Multi-Stage is selected from the 03G Final Charge Stage menu.

• Load Support AAC – The inverter is in the Load Support (Amps AC)

mode because the inverter load is requiring more power than the incoming AC source can provide on its own. The inverter pulls the additional current— that is needed for the loads—from the inverter batteries to keep the incoming AC current from exceeding the SETUP: 03A AC Input Amps setting.

Info: The Load Support AAC feature operates in parallel with the AC

input to support the inverter loads and is only available on MSH Series inverter/chargers. It is only active when the inverter is enabled (INV LED is on).

Info: When the inverter is in Inverter Standby mode (charging and

pass-thru), the current is normally a positive value. However, in Load Support AAC mode, the inverter amps reading is a negative number to indicate how much current is being provided/removed from the inverter batteries. The inverter batteries will continue to provide current to assist the AC input current until the battery reaches 0.5 volts (12-volt systems), 1.0 volts (24-volt systems) , and 2.0 volts (48-volt systems) above the SETUP: 02B LBCO setting.

• Load Support VDC – The inverter/charger is in the Load Support (Volts

DC) mode because an external DC source (solar, wind, etc.) is providing more current than needed—which causes the battery voltage to rise. The inverter/charger reduces the incoming AC current in an effort to keep the battery voltage from rising above the temperature-compensated SETUP: 03B Battery Type setting.

Info: The Load Support VDC feature operates in parallel with the AC

input to support the inverter loads and is only available on MSH Series inverter/chargers. This feature is only active in Bulk, Absorb, Float or EQ Charge modes and when the inverter is enabled (INV LED is on); it is deactivated if the charger is in Charger Standby.

• Silent – This displays at the end of the Absorption stage if Silent is

selected from the 03G Final Charge Stage menu. In Silent mode, the charger is not actively charging but does monitor the battery voltage. When the battery voltage reaches the Set DC Volts to ReBulk setting (from 03G Final Charge Stage menu) the charger will restart a Bulk and Absorb charge cycle, and then transition back into Silent mode at the end of the Absorb cycle.

Page 62

5.0 Operation

5.3.3 Secondary Scrolling Status Messages

These displays alternate with the inverter/charger status to indicate other pertinent messages.

• AC In-Disabled – AC power is present at the inverter’s AC input, but the

inverter/charger is prevented from connecting to any incoming AC because the AC In-Disabled setting is selected from the CTRL: 01 ACIn Control menu.

• SOC Connect – AC power is present at the inverter’s AC input, but the

battery bank State of Charge needs to reach the Set Connect SOC setting from the SETUP: 02E AC IN - SOC menu in order for the inverter/charger to connect to the incoming AC.

• Time Connect – AC power is present at the inverter’s AC input, but the

time of day needs to fall within the Set Connect Time and the Set Disconnect Time settings per the SETUP: 02C AC In - Time menu in order for the inverter/charger to connect to the incoming AC.

• VDC Connect – AC power is present at the inverter’s AC input, but the

battery voltage needs to fall below the Set Connect Volts setting from the SETUP: 02D AC IN VDC menu in order for the inverter/charger to connect to the incoming AC.

• Gen Warm-up – The ME-AGS-N has commanded a generator to run,

but the inverter will not connect to the generator’s DC output until the

generator warm-up time is complete. Note: Requires the optional ME-AGS-N

Auto Gen Start module to be installed.

5.3.4 Fault Mode Messages

The FAULT LED comes on and a fault status is displayed when an abnormal condition is detected. Use the information in this section to identify and correct the issue.

Info: Many of the faults automatically clear once the fault is resolved.

Some will require a manual restart. This requires the ON/OFF INVERTER button on the router to be pressed and released. Finally, if the fault will not clear, an inverter reset (Section 6.2) or power reset (Section 6.3) may be required.

5.3.4.1 System Fault Messages

These fault messages are usually caused by some external issue that directly affects the inverter/charger system.

• AC Backfeed – This fault message causes the inverter to shut down

because AC voltage from an external AC source has been detected on the inverter’s AC output. When the unit shuts down because of this fault condition, an inverter reset or power reset will be required to resume operation (see Section 6.2 to reset the inverter).

Remedy: This fault usually occurs because the AC output wiring is

connected to (or able to be connected to) the incoming AC source. When this fault happens, all system wiring should be re-checked to ensure the incoming hot and/or neutral wires are not able to be connected to the AC output.

• AC Overload – This fault message displays when the AC load on the

inverter/charger’s output has exceeded the inverter’s AC current protection limits. If the overload condition lasts for <10 seconds, the fault will automatically clear and the unit restarts and resumes operation. However, if the overload occurs for more than 10 seconds, the unit will shut down and the fault will require a manual restart.

Page 63

5.0 Operation

Remedy: This fault may occur because the connected AC loads are

larger than the inverter’s output capacity, there is a wiring short on the output, or the output wires are incorrectly installed. Once the AC loads are reduced or the output wiring is corrected, the inverter can be restarted after a manual restart.

• Breaker Tripped – The AC input breaker on the inverter/charger has

opened due to excess current ﬂ ow through the inverter to the AC loads.

Remedy: After reducing the AC loads, push in the inverter’s AC input

circuit breaker to reset and resume operation.

Info: While in Charger mode, the inverter’s AC input breaker could

nuisance trip if the loads on the inverter’s output exceeds the current rating of the inverter’s input circuit breaker.

• Dead Battery Charge – This fault indicates that the inverter has been

connected to an AC source (grid or generator) and has determined that the battery bank is either highly discharged or not connected. The inverter is attempting to close its internal relay and begin charging, but has detected less than 9 volts (12-volt models), 18 volts (24-volt models), or 36 volts (48-volt models) on the battery bank.

Remedy: Check the DC voltage at the inverter’s DC terminals and

compare it with the DC voltage at the battery bank. These two voltages should be very close (<0.5 VDC difference). If not, check to ensure all connections are tight and the fuse/circuit breaker between the inverter and battery bank is good.

This fault automatically clears once current is able to ﬂ ow into the battery from the battery charger—this may take anywhere from a few minutes to a few hours depending on the condition of your batteries. This fault can also be cleared if the AC input is removed.

• FET Overload – This fault message indicates the inverter/charger was

running normally, but the temperature of the FETs (Field Effect Transistors) started rising abnormally fast.

Remedy: Allow the inverter to cool down, then press the remote’s

INVERTER ON/OFF pushbutton (manual restart) to resume operation. If the fault returns, perform an inverter reset (see Section 6.2). If the fault continues, disconnect all the inverter’s AC output wires and perform a power reset (Section 6.3). If this fault does not clear after doing the power reset, the inverter will require service.

• High Battery – The inverter has turned off because the battery voltage

is at a very high level. This fault message displays and the FAULT (red) LED turns on when the battery voltage is above the High Battery Cut-Out (HBCO) value. This fault automatically clears and the inverter resumes operation when the battery voltage drops 0.3 VDC (12v models), 0.6 VDC (24v models), or

1.2 VDC (48v models) below the HBCO value.

Info: The HBCO value is dependent on your inverter revision and

model. Normally, the HBCO value for the ME/MM/RD Series’ inverters is 16 VDC (12-volt models) or 32 VDC (24-volt models); and, the HBCO value for the MS/MMS Series’ inverters is 17 VDC (12-volt models), 34 VDC (24-volt models), or 68 VDC (48-volt models).

Page 64

5.0 Operation

Info: This fault can occur whether the inverter is “inverting”, “search-

ing” or “off”.

Remedy: This fault usually occurs when an external DC charging

source is charging the inverter’s battery bank. Turn off any other additional charging source to allow the DC voltage level to drop.

• High Battery Temperature – This fault message indicates the inverter/

charger has shut down because the Battery Temperature Sensor (BTS) has reached a temperature greater than 54°C/129°F.

Remedy: Once the BTS has cooled down (≤49°C/120°F) it auto-

matically restarts and continues operation. As a precaution, check the area where the BTS is located; if placed on a battery, ensure they are not overheated, or that the BTS hasn’t been placed in a hot area or near a hot device. If neither of these are the issue, then monitor the Batt Sensor display under the TECH/01 Temperatures menu—this reading should be above 54°C/129°F. Now remove the BTS from the inverter BTS port. If the Batt Sensor reading goes to 25°C/77°F, replace the BTS. If the reading does not go to 25°C/77°F, then inspect the BTS port for cleanliness and/or have the inverter/ charger serviced.

• High Volts AC – This fault causes the AC input to be disabled because

a very high AC voltage (>150 VAC or >300 volts for export inverters) has been detected on the AC input.

Remedy: Remove all AC power from the inverter’s AC input for at

least 15 minutes to clear this fault. Ensure only 120VAC power is connected to each of the inverter’s AC inputs.

• Low Battery – The inverter has turned off to prevent the batteries from

being over-discharged. The fault message displays and the FAULT (red) LED illuminates when the battery voltage drops below the SETUP menu’s 02B LBCO Setting for more than one minute. The fault will clear and automatically the inverter will restart and resume operation when the battery voltage rises to ≥12.5 VDC (12-volt models), ≥25.0 VDC (24-volt models), or ≥50.0 VDC (48-volt models).

Info: This fault can only occur if the inverter status is “Inverting”

or “Searching.”

Remedy: This fault will also automatically clear if AC power such as

utility power or a generator is connected to the inverter/charger’s input and battery charging begins.

• Overcurrent – This fault may be the result of an excessive AC load and

causes the inverter to shut down to protect internal power components. If the overload condition lasts for less than 10 seconds, the unit automatically restarts and resumes operation. However, if the overcurrent condition occurs for more than 10 seconds, the unit will shut down and requires a manual restart.

Remedy: This fault usually occurs because the connected AC loads

are larger than the inverter’s output capacity, there is a wiring short on the AC output, or the output wires are incorrectly wired. Once the AC loads are reduced or the output wiring is corrected, manually restart the inverter to resume operation. If this fault condition continues perform a inverter reset.

Page 65

5.0 Operation

• Overtemp – This fault message indicates the inverter/charger has shut

down because the internal power components (FET’s and/or Transformer) have exceeded their safe temperature operating range. When the unit has cooled down the fault will automatically clear and the unit will restart and continue operation.

Remedy: If the fault occurs while inverting, reduce the load on the

inverter. If it occurs while charging, turn down the charge rate. If this fault happens often, ensure the inverter is not in a hot area, has proper ventilation, and the cooling fans inside the inverter are working.

• Stuck Relay – This fault message displays when the inverter is

“inverting”, but has determined that the internal AC pass-thru relay that should be open while inverting, is closed.

Remedy: The AC pass-thru relay is most likely stuck. A relay usu-

ally sticks because of damage to the contacts from trying to handle currents greater than they are rated. This is usually caused by not protecting the relay from handling high continuous currents, or by switching high current inductive loads. The internal relay contacts are rated to handle 30 amps AC continuously and should be protected with a breaker sized no larger than 30 amps. If you are connected to an AC source (grid or generator) and running large inductive loads (i.e. pumps, motors, etc.) on the inverter output, turn those particular loads off prior to removing the AC input source. This fault requires an inverter or power reset to clear.

• Tfmr Overtemp – This fault message displays when the transformer

causes the inverter to shut down to protect the internal power transformer from damage. Once the transformer cools down, the inverter automatically restarts and resumes operation.

Remedy: If the fault occurs while inverting, reduce the load on the

inverter. If while charging, turn down the charge rate. If this fault occurs often, ensure the inverter is in a cool location, has adequate ventilation, and the internal cooling fans are operational.

• Unknown – This fault message displays when the inverter/charger has

sent a fault code that cannot be identified by the remote.

Remedy: For more information or assistance in identifying the actual

fault status, contact Magnum Energy Technical Support.

5.3.4.2 Stacking Fault Messages

A fault condition may occur when multiple inverters are connected or stacked together that is not possible on a single inverter installation.

• StackClock – There is a stacker cable problem; or, one inverter is losing

synchronization with the other inverter.

Remedy: Ensure you are using the correct stacking cable (is not a

telephone/data cable, is a custom made cable). Inspect the stacker cable and reconnect at both ends (listen and make sure you hear an audible “click” from the connectors at both inverters).

Info: This fault has been known to occur when a Magnum Energy

accessory is plugged into the Stack Port, but the installation is not using multiple inverters in a stacked conﬁ guration. If this occurs, perform an inverter reset (see Section 6.2).

Page 66

5.0 Operation

• Stack Mode – A problem with the “other” stacked inverter has been

detected. Check that unit for a fault condition.

Remedy: This fault will automatically clear when the fault with the

other inverter is corrected.

• StackPhase – Either: 1. The AC input wiring is incorrect; 2. One phase

was lost from the AC input source; 3. One of the inverter’s internal transfer relays is bad; or, 4. The inverter’s AC input circuit breaker may be open.

Remedy: If this fault doesn’t clear after checking these four recom-

mendations, perform an inverter reset (see Section 6.2).

5.3.4.3 Internal Fault Messages

The inverter continually monitors several internal components. If a condition inside the inverter occurs that does not allow proper operation, one of the following internal fault messages displays and the inverter shuts down to help protect itself.

Remedy: If one of the following internal faults occurs, the inverter

will require an inverter or power reset to clear the fault. See Section 6 to perform an inverter or power reset. After resetting the inverter, press the ON/OFF INVERTER pushbutton on the remote to turn the inverter on and verify the fault has cleared (i.e. manual restart). If the internal fault remains or returns, the inverter will require repair at an Magnum Energy Authorized Service Center, for locations see

http://www.magnumenergy.com/Service/ServiceCenters-US.htm.

• Internal

down after the inverter has been inverting—the inverter output circuit can no longer detect any AC output voltage or current.

• Internal Charger – This fault message displays when the FET bridge

shuts down because the charger circuit is trying to provide maximum current, but is not detecting any current or voltage rise to the battery bank.

• Internal NTC – This fault message displays when the internal NTC

(Negative Temperature Coefﬁ cient) temperature sensor suddenly causes a very large but unexpected temperature change.

Bridge – This fault message displays when the FET bridge shuts

• Internal Relay – This fault message displays when the internal AC

transfer relay is not closed while charging.

6.0 Troubleshooting

6.1 Troubleshooting Tips

6.1.1 Inverter Problems

• Inverter turned on, green LED on inverter blinking, no output:

Inverter is in Search mode. Either defeat Search mode, if not needed, or turn on loads greater than the Search Watts setting.

6.1.2 Charger Problems

• Unit won’t transfer to Charge mode with AC applied: Is the charge

(CHG) LED on remote blinking? If not, the charger does not recognize the incoming AC being within acceptable limits. Measure the input AC voltage at the inverter input terminals – should be 120 VAC +/- 20 VAC (230 VAC +/- 40 VAC for export models). Also, check that the VAC Dropout setting on the remote is 80 VAC or less (160 VAC or less for export models). If the CHG LED is blinking, the transfer relay should close within 20 seconds and begin charging. If the LED is on solid, the relay should be closed and the charger should begin charging.

• Transfer relay closes then opens and continues to cycle: AC

voltage is too low, or has transients that drop the AC voltage momentarily. Change the VAC Dropout setting to 60 VAC (110 VAC for export models) and check for improvements. If the cycling continues, back off the charge rate from 100% to 10% (or “OFF”, if available).

This cycling may also be caused if the AC output of the inverter is connected to the inverter’s AC input. Check for proper input and output AC wiring.

• Charger not charging even though Charge LED is on steady and the unit says “Charging”: Full charge rates are not obtained in Charging

mode. Full charge rates will occur only after this mode changes to Bulk Charging, Absorb Charging, or Float Charging modes.

• Charger not charging even though Charge LED is on steady and the unit says “Bulk Charging” (or “Absorb Charging”): Check the DC

amps meter and DC voltmeter on the ME-ARC display. It should be 80% or more of rated charge current if the battery voltage is under 14.0 VDC (28.0 VDC on 24-volt models or 48.0 VDC for 48-volt models). If not, check the 03C Max Charge Rate setting and verify the setting is 80% or greater. Still low charge rate? Check the 03A AC Input Amps setting. If no AC loads are being passed through the inverter, the 03A Input Amps setting must be 15 amps (25 amps for 3kW unit) or greater, to receive full charge rate.

• Charger says “Float Charging” not “Bulk Charging” when the AC is ﬁ rst plugged in: Check DC voltmeter on the ME-ARC display. If

the battery is >13.0 VDC (>26.0 VDC for 24-volt models or >52.0 VDC for 48-volt models) then the battery was already charged and the charger automatically goes to Float charging to keep from overcharging the batteries. Try the Restart Bulk setting from the 02 CHG Control menu.

• Charge amps are lower than expected, or is 0 amps DC: Measure

input AC voltage and increase if the input voltage is under 90 VAC. The charge rate is reduced to keep the input voltage above 90 VAC. Also, check the 03A Input Amps and 03C Max Charge Rate settings to determine if the current is being limited.

• Charger output voltage is different than expected: Check the

Battery Temperature Sensor (BTS) temperature. If the BTS is installed, the charge voltage settings will increase if the temperature around the BTS is below 77° F (25° C), and decrease if the temperature around the BTS is higher than 77° F (25° C).

6.2 Performing an Inverter Reset

To perform an inverter reset (also known as a soft reset), press and hold the Power ON/OFF button (see Figure 6-1) for approximately ﬁ fteen (15) seconds until the Charging/Inverting Status LED comes on and ﬂ ashes rapidly. Once the rapid ﬂ ashing has begun, release the Power ON/OFF button. The Status LED will go off after the button is released.

After the inverter reset is completed, press the Power ON/OFF button to turn the inverter ON.

Some older inverter models do not allow an inverter reset. If the inverter reset fails, you will need to perform a power reset using the procedure below. In either case, if an internal fault does not clear the inverter will require repair at a Magnum Authorized Service Center (ASC).

Info: The Power ON/OFF button is a small momentary type switch

which operates by lightly pressing and releasing.

Info: All adjustable inverter/charger settings in the ME-ARC (except

for the SETUP menu’s 01B Contrast, 01C Backlight, and the CTRL menu’s 03 Gen Control—which revert back to default) are saved in non-volatile memory and are preserved until changed. This occurs even if an inverter reset is performed, or if all power to the remote or inverter is removed.

1. Press and hold the Power ON/ OFF pushbutton for 15 seconds.

2. Watch the Charging/Inverting Status LED, after approximately 15 seconds it should come on and flash rapidly (almost a flutter) to indicate the inverter has reset. The Status LED will go off after the pushbutton is released.

Figure 6-1, Performing an Inverter Reset

6.3 Performing a Power Reset

To perform a power reset (also known as a hard reset):

1. Remove all AC power (utility or generator power) to the inverter.

2. Open all the inverter DC disconnects (or disconnect the positive battery cable to the inverter).

3. Ensure the inverter(s) and the remote are disconnected from all AC and DC power (the remote display will be blank).

4. After the inverter(s) has been disconnected from all power for 30 seconds, reconnect the inverter DC disconnects (or reconnect the positive battery cable) and resume operation.

Info: If DC disconnects are not used, there may be a momentary

spark when the positive battery cable is connected to the inverter’s terminal. This is normal and indicates that the inverter’s internal capacitors are being charged.

SETUP: 04A Gen Run VDC Menu

This menu starts/stops the generator based on the battery voltage as shown on the METER button’s 03B DC Volts-AGS menu. This menu provides the option to start the generator when the battery voltage gets low, and to stop the generator once the battery reaches a higher voltage level, or has been fully charged and goes into the Float Charge stage. Using voltage to automatically start and stop the generator is a common method because it is considered the simplest and easiest to understand. The 04A Gen Run VDC menu also has a delay setting to minimize nuisance starts/stops and the short cycle run times of the generator.

• Set Start Gen Volts – This setting will start the generator when the

battery voltage (on Terminals #3 & #4) decreases to or below this setting continuously for the duration of the Set Start Volts Delay setting.

Default setting: Set Start Gen Volts = 11.5 VDC (12v), 23.0 VDC

(24v), 46.0 VDC (48v)

Range: OFF, 9.0-15.9 VDC (12v), 18.0-31.8 VDC (24v), 36.0-63.6 VDC (48v)

Where should I set Start Volts? When setting the VDC start voltage, it

must be high enough to not over-discharge the battery, but also low enough to keep from nuisance starting the generator. Typically, start volts is set based on what is determined to be approximately 50% of the battery capacity. Since this is an inverter/battery system, and the battery is normally loaded, the VDC used to determine 50% battery capacity should be set lower than what is shown on typical battery voltage SOC charts (approximately 11-11.5 in a 12-volt system), which show the battery at rest (not loaded).

Info: The DC voltage the AGS uses to determine when to autostart is

displayed in the AGS: 08 AGS TECH menu under the AGS VDC meter.

Example: Using a 12-volt battery as an example, a typical SOC (State of

Charge) battery chart will show that 12.2 VDC is considered 50% SOC. This voltage is a battery “at rest,” meaning it has no load connected and has been at rest for a minimum of 30 min. While this voltage is accurate under these at rest conditions, this same voltage with a load applied means the battery is well above 50% SOC, and should be set much lower. The larger the battery bank the less the voltage will be affected by a load applied to the battery bank. A typical start voltage setting would be between 11.0 VDC - 11.5 VDC for a 12-volt system.

• Set Start Volts Delay – This setting determines how long the Start

Gen Volts parameter must be continuously maintained before the gen-

erator autostarts. This ensures the generator does not nuisance start. By setting a delay, momentary surge loads will not start the generator when the battery voltage dips due to the heavy load applied to the battery.

Default setting: Set Start Volts Delay = 120 Seconds Range: 0-127 Seconds, 1-127 Minutes

Where should I set Start Volts Delay? Determine what loads will be

running when the generator needs to start. The larger the load the shorter the delay time setting. When a large load is applied to the battery bank the battery voltage drops quickly, so the delay time should be short to ensure the batteries are not over-discharged. If you are unsure what loads might be running or where to set the start delay, error on setting a shorter time such as the default of two minutes (to protect batteries from over-discharge).

Page 73

7.0 Using an AGS Module

• Set Stop Gen Volts – This setting will stop the generator when the

battery voltage (on Terminals #3 & #4) increases to or above this setting continuously for the duration of the Set Stop Volts Delay setting. To allow the battery bank to go through a full bulk and absorption charge, this setting should be set to Float.

Default setting: Set Stop Gen Volts = 14.4 VDC (12v), 28.8 VDC

(24v), 57.6 VDC (48v)

Range: OFF, 9.1-16.0 VDC (12v), 18.2-32.0 VDC (24v), 36.4-64.0 VDC

(48v), Float

Where should I set Stop Gen Volts? Typically, when using a generator

to charge batteries, most individuals only charge the batteries to 80-85% to compromise between minimizing fuel usage and maximizing battery life. This is done by having the generator start on low battery voltage, and then stop at a higher voltage (i.e., the Stop Gen Volts setting). When deciding where to set the Stop Gen Volts setting, it must be lower than the invert- er’s Absorb Voltage setting (determined by the SETUP: 03B Battery Type menu). Otherwise, the charger will enter Absorption Charge mode—which is required to maintain the batteries at a constant voltage level—and the battery voltage will not reach the Stop Gen Volts setting, which will cause the generator to run until it is out of fuel or until it reaches the SETUP: 04F Max Gen Run Time setting.

Therefore, after reading this some will think that they should just set the Stop Gen Volts setting slightly lower than the absorption level to ensure the charger always reaches the Stop Gen Volts setting before it goes into the Absorption Charge mode. However, temperature changes can affect the

absorb voltage setting¹ and may require you to readjust the Stop Gen Volts

setting seasonally. If you are in a normally cold climate (<32°F), the actual absorb charge voltage will increase. So, the Stop Gen Volts setting should be set well above the absorb voltage setting (~.5V above for 12-volt systems). If you are normally in a hot climate (>95°F), the actual absorb charge voltage will decrease. In that case, the Stop Gen Volts setting should be set well below the absorb voltage setting (~.5V below for 12-volt systems).

A simpler way to charge the batteries to 80-85% and to automatically allow a temperature-compensated charge to the batteries (no seasonal adjustment required) is accomplished using the settings below:

• Set the Stop Gen Volts setting to Float

• Set the Absorb Voltage setting (SETUP: 03B Battery Type) to the volt- age level at which you want the generator to turn off (normally ~ 14.5 volts for ﬂ ooded batteries in a 12-volt system)

• Set the Absorb Done Time setting (SETUP: 03E Absorb Done Time) to

0.1 hours (lowest setting)

Using these settings, when the batteries reach a low voltage level the generator turns on (per the Set Start Gen Volts setting) and charges the battery to the temperature-compensated Absorb Voltage setting. After reaching the absorption voltage level, the inverter/charger goes into Absorption Charge mode and is there for only six minutes (0.1 hours) before it goes to Float Charge mode. Once the inverter/charger enters Float Charge mode, the AGS will autostop the generator.

Note¹: When the inverter’s Battery Temperature Sensor (BTS) is connected,

the actual absorb charge voltage will increase or decrease to ensure correct charging as the battery temperature changes.

Page 74

7.0 Using an AGS Module

Info: Battery life will be reduced if the batteries are only charged

to 80-85% regularly. It is highly recommended to charge the batteries to 100% as often as possible (~ once a week, or every other discharge cycle) in order to avoid sulfation of the battery plates. Using the SETUP: 03E Absorb Done Time menu, the absorption charge time can easily be changed to a longer duration to increase the batteries’ state of charge.

• Set Stop Volts Delay – This setting determines the amount of time the

generator will run after the Stop Gen Volts setting has been satisﬁ ed.

Default setting: Set Stop Volts Delay = 120 Seconds Range: 0-127 Seconds, 1-127 Minutes

SETUP: 04B Gen Run Time Menu

This menu starts and stops the generator based on a speciﬁ c time of day. This feature uses the ME-ARC’s internal clock to start and stop the generator at the selected times.

Info: Ensure the remote’s clock is correct. If needed, refer to the

ME-ARC owner’s manual for guidance on setting the time on the remote clock.

Info: The ME-ARC clock is powered from the inverter thru the remote

cable. If the ME-ARC or inverter loses power, the clock will lose the correct time and must be reset.

• Set Gen Run Time – This setting allows set times to be established to

turn the generator on and off each day. Select ON to set speciﬁ c times of day to start and stop the generator.

Default setting: Set Gen Run Time = OFF

• Set Start Gen Hour – Set the hour the gen will start each day.

• Set Start Gen Minute – Set the minute the gen will start each day.

• Set Start Gen AM-PM – Set the time period the gen will start.

• Set Stop Gen Hour – Set the hour the gen will stop each day.

• Set Stop Gen Minute – Set the minute the gen will stop each day.

• Set Stop Gen AM-PM – Set the time period the gen will stop.

Why should I set a speciﬁ c time of day to start/stop the generator?

Starting and stopping at a particular time of day can be useful if you want to run the generator for other uses while charging the batteries. You may require the generator to run a heavy load (like a well pump or machinery) every day at the same time. You may also want the generator to run after you leave for work each day to avoid having to hear it running.

SETUP: 04C Gen Run Amps Menu

This menu starts the generator based on the amount of AC amps needed to handle the load the inverter is running. The METER button’s 02C Load Amps menu is used to determine how much load the inverter is currently running when in Inverter mode.

Info: The 04C Gen Run Amps menu is only applicable to Magnum’s

MS-PAE, ME-PE and MSH Series inverters.

Why use Gen Run Amps? This setting is useful when there is a large load

or a combination of loads that the inverter can run, but doing so quickly depletes the battery bank (motors, well pumps, A/C units, freezer, etc.).

Page 75

7.0 Using an AGS Module

• Set Start Gen AC Amps – This setting determines when the generator

would start depending on the AC amps level of the load the inverter is running. In order for the generator to autostart, the load’s amps level must be maintained continuously above the Start Gen AC Amps setting for the duration of the Start Amps Delay setting.

Default setting: Set Start Gen AC Amps = OFF Range: OFF, 5-60 Amps

• Set Start Amps Delay – This setting determines the amount of time

that the inverter load’s current must continuously remain above the Start Gen AC Amps setting for the AGS to initiate an autostart.

Default setting: Set Start Amps Delay = 120 Seconds Range: 0-127 Seconds, 1-127 Minutes

• Set Stop Gen AC Amps – This setting determines when the generator

would stop depending on the drop in the AC amps needed for the load the inverter is running. In order for the generator to autostop, the load amps level must drop continuously below the Stop Gen AC Amps setting for the duration of the Stop Amps Delay time setting.

Default setting: Set Stop Gen AC Amps = 4 Amps Range: 4-59 Amps

• Set Stop Amps Delay – This setting determines the amount of time

that the AC load must be continuously smaller than the Stop Gen AC

Amps setting before the generator automatically stops.

Default setting: Set Stop Amps Delay = 120 Seconds Range: 0-127 Seconds, 1-127 Minutes

Where should I set Gen Run Amps? Typically, the generator should start

when the AC load amps is >70-75% of the inverter AC current output rat-

ing¹. This keeps the inverter from running too large a load and also keeps

the batteries from cycling unnecessarily. Set Stop Gen AC Amps just below the start amps to ensure the large load has turned off. Set the start delay time so surge loads don’t trigger a false start, and the stop delay time is long enough to ensure the load has turned off.

Amps Start/Stop Example: In this scenario, most AC loads typically do

not exceed 20A when in Inverter mode. When a freezer or well pump starts, the load exceeds 30A so the battery voltage starts to drop quickly. Instead of cycling the batteries to a low voltage, set Start Gen AC Amps to 25A with a 60-second delay (using Set Start Amps Delay menu). Set the Stop Gen AC Amps menu to 20A with a 60-second delay (using Set Stop Amps Delay menu). After 60 seconds of detecting a larger than 25A load on the inverter, the generator autostarts and powers the loads and recharges the batteries. Once the AC amps load drops below 20A for 60 seconds, the gen will turn off.

SETUP: 04D Gen Run SOC Menu

Info: This feature requires the optional ME-BMK (Battery Monitor

Kit). Refer to your ME-BMK owner’s manual to operate.

This menu starts and stops the generator based on the SOC (State of Charge) reading from the attached battery monitor (see ME-BMK owner’s manual) as shown on the METER button’s 04A BMK SOC display. This is considered the best overall method for using AGS settings to start and stop your generator.

Note¹ – For a 4000 watt inverter, set Start Gen AC Amps at 25A.

Page 76

7.0 Using an AGS Module

The BMK already uses voltage, time, and current to determine the true SOC of the batteries, so little guesswork is needed to determine the settings.

• Set Start Gen SOC – This menu is used to set the SOC level for auto-

starting the generator.

Default setting: Set Start Gen SOC = OFF Range: OFF, 20-90%

• Set Stop Gen SOC – This menu is used to set the SOC level for

autostopping the generator.

Default setting: Set Stop Gen SOC = 90% Range: 21-100%

Info: There is no start or stop delay time needed since the ME-BMK

already displays an accurate state of charge of the batteries.

Where should I set Gen Run SOC? Most battery manufacturers recom-

mend that for optimum life, deep-cycle batteries should not be discharged below 50% SOC. The ME-BMK determines the battery’s SOC by using a DC shunt to measure the ﬂ ow of current in and out of the battery. The SOC meter gives you an accurate reading of remaining capacity in the battery bank. Set the Start Gen SOC level to 50%, or to 60% if you do not want to discharge the batteries quite as much. When considering the Stop Gen SOC setting, keep in mind that running the generator past 90% SOC delivers very little current to get that last 10% into the batteries. Thus, it is common to stop the generator at 90% to save fuel and run time on the generator. However, if the SOC stop setting is less than 100%, the batteries should be charged to 100% as often as possible (~ once a week, or every other discharge cycle) in order to avoid sulfation of the battery plates.

SETUP: 04E Gen Run Temp Menu

This menu allows you to set and enable a temperature value that will automatically start the generator—typically to power an air conditioner for cooling—based on an increase in temp, or by using an A/C thermostat control.

Info: The optional ME-PT1 or ME-PT2 pigtail adapters can be used to

connect an A/C or relay control circuit. For more information, refer to the instruction sheet for each pigtail adapter (part number 640025 for ME-PT1 instructions, or 64-0026 for ME-PT2 instructions).

Info: This temperature autostart feature requires that the AGS’s

remote temp sensor cable or an optional ME-PT1 or ME-PT2 pigtail adapter be connected to the AGS’s REMOTE port. When using the remote temperature sensor, the location of the temperature sensor determines the area being monitored for temperature.

• Set Gen Run Temp Start – This menu is used to enable and set the

temperature that triggers a generator autostart.

65F - 95F (18C - 35C) – These settings determine the rising tempera-

ture value that triggers a generator temperature autostart.

Ext Input – This setting is used when an optional pigtail adapter (ME-

PT1, or ME-PT2) is used. When an AGS pigtail adapter is connected to the AGS’s REMOTE port, an external command—either from a thermostat connection on an air conditioner control circuit or an external relay control circuit—is recognized and causes the generator to start.

Default setting: Set Gen Run Temp Start = OFF Range: OFF, Ext Input, 65-95F or 18-35C

Page 77

7.0 Using an AGS Module

Info: If the temperature start feature is not needed, ensure this

setting is set to the OFF position.

• Set Gen Run Temp Time – This menu sets the amount of time the

generator runs after a temperature autostart.

Default setting: Set Gen Run Temp Time = 2.0 Hrs Range: 0.5-25.5 Hrs

When the temperature around the remote temp sensor (per the METER: 03D AGS Temp display) increases to the Gen Run Temp Start setting, the genera-

tor immediately starts and runs based on the Gen Run Temp Time setting. When this run time period is ﬁ nished, the temp sensor reading is checked. If the temperature sensor (or thermostat control if using the optional pigtail adapter) reading is below the Gen Run Temp Start setting, the generator will autostop. If the temperature sensor (or thermostat control) reading is above the Gen Run Temp Start setting, the generator will continue to run for a second run time period. At the end of this second run time period, the temperature sensor reading (or thermostat control) is checked again. This cycle continues as long as the CTRL: 03 Gen Control menu is set to AUTO, or the SETUP: 04F Max Gen Run Time setting is reached, whichever occurs ﬁ rst.

Why should I use Gen Run Temp? Typically, in a mobile application such

as in an RV or on a boat where the air conditioning (A/C) unit is too much power for the inverter to run from the batteries, this feature is used to start a generator to run the A/C unit. Many RV and marine customers travel with pets and they do not want to leave the pets inside on a hot day. With this feature, you could set the A/C unit to turn on and leave. Whenever the inside temperature rises to the start setting, the generator autostarts to provide power to the A/C unit. This would keep the area cool and comfortable—plus, while the generator is on, the inverter batteries are being charged.

Where should I set Gen Run Temp Start? If using this feature to power

an A/C unit, the Gen Run Temp Start setting should be slightly above the temperature setting of the thermostat controlling the air conditioner unit. Once the Gen Run Temp Start setting is reached, the gen starts providing power to the A/C unit. The reason the Gen Run Temp Start is set above the A/C unit’s thermostat setting is to ensure the A/C unit runs when the generator starts. If the Gen Run Temp Start setting is below that of the A/C unit’s thermostat setting, the generator runs but the A/C unit is not calling for a run period or cooling. In other words, your generator is running but the power is not being used by the A/C unit—resulting in wasted fuel and run time.

Info: If using the temperature autostart feature to start a genera-

tor that is powering two air conditioners, it is suggested that the second air conditioner’s thermostat be set 2° to 5° higher than the ﬁ rst air conditioner. This staggered setting allows the ﬁ rst air conditioner to start and run in an effort to keep the coach cool. If the temperature continues to rise inside the coach, the second air conditioner turns on.

How long should I set the Gen Run Temp Time? When using the tem-

perature autostart feature, the generator autostarts and runs until the Gen Run Temp Time setting or the SETUP: 04F Max Gen Run Time setting is reached, whichever occurs ﬁ rst. This means you could set the time to the lowest time setting (0.5 Hrs), knowing the generator will attempt to run until the temperature setting is met.

Page 78

7.0 Using an AGS Module

SETUP: 04F Max Gen Run Time Menu

This menu is used to set the maximum time the generator will run if the generator has been started by one of the AGS’s autostart settings.

• Set Max Gen Run Time – Set this to the maximum amount of time you

want the generator to run once it has been autostarted.

Default setting: Set Max Gen Run Time = 12.0 Hrs Range: OFF*, 0.1-25.5 Hrs

* The Max Gen Run Time setting can only be turned off using a ME-AGS-

N with Rev ≥ 5.2.

Why should I use Max Gen Run Time? This setting is used to ensure the

generator does not run longer than desired after an autostart. Setting a max run time ensures the generator stops if the autostop setting cannot be satisﬁ ed. For example, if the fuel capacity of your generator is ﬁ ve hours, set the Max Gen Run Time setting to 4.5 hours to ensure it does not run out of fuel.

Info: When the generator autostarts from one of the autostart

settings, it will autostop when the autostop parameter for that particular setting has been satisﬁ ed. For example, if the generator starts due to the 04A Gen Run VDC menu’s autostart setting, it then stops once it satisﬁ es the Stop Gen Volts autostop setting. However, the Max Gen Run Time setting overrides any autostop setting. If the generator stops because the Max Gen Run Time setting has been reached, the Fault MaxRun status will occur. If this happens, you may have to increase the Max Gen Run Time setting or adjust the autostop setting to ﬁ nish sooner. If multiple autostart settings are set in the 04 AGS Setup menus and a Fault MaxRun status occurs, refer to the METER button’s 03A AGS Status menu to identify which condition autostarted the generator. This way you will know which auto condition is running longer than the Max Gen Run Time setting.

Info: The Max Gen Run Time menu uses the METER button’s 03C

Gen Run Time display to determine the generator’s run time.

Info: If the generator is stopped due to the Max Gen Run Time

parameter being met, the status becomes Fault MaxRn and the generator will not autostart again until you clear the fault.

SETUP: 04G Quiet Time Menu

This menu is used to enable the Quiet Time feature, and to set the period of time each day in which the generator is not allowed to automatically run. The Quiet Time start setting will prevent the generator from starting even if one of the start parameters is met. If any autostart parameter in the 04 AGS Setup menus has been met and the generator is running when the Quiet Time start setting is reached, the generator will turn off. The generator will not try to autostart until the Quiet Time stop setting has been reached and an autostart condition is once again satisfied.

The ME-ARC contains a real time clock that must be set for proper operation of the SETUP: 04G Quiet Time Menu feature.

• Set Quiet Time – Set to On (allows you to set the start and stop times).

Default setting: Set Quiet Time = OFF Range: OFF, ON, [daily start and stop time settings (12:00AM-12:00PM)]

Page 79

7.0 Using an AGS Module

• Set Start Quiet Hour – Set the hour for Quiet Time to start.

• Set Start Quiet Minute – Set the minute for Quiet Time to start.

• Set Start Quiet AM-PM – Set AM or PM for the start of Quiet Time.

• Set Stop Quiet Hour – Set the hour for Quiet Time to stop.

• Set Stop Quiet Minute – Set the minute for Quiet Time to stop.

• Set Stop Quiet AM-PM – Set AM or PM for the stop of Quiet Time.

Why should I use Quiet Time?

rules or local regulations that prevent generators from running (sleep hrs.). If there are no local rules or regulations, you may not want to use Quiet Time – which would allow the generator to run at any time in a 24-hour period.

Where should I set Quiet Time? Set the Quiet Time start and stop settings

to coincide with local noise requirements, or for a specific time period that you do not want the generator to automatically run each day.

• Set Quiet Time Topoff – This menu sets the time the generator will

autostart and run before Quiet Time starts. The generator will only

start on Quiet Time Topoff if the battery voltage (or battery SOC¹) start

parameter is within a specified range.

Default setting: Set Quiet Time Topoff = OFF Range: OFF, 30-120 Minutes

What is Quiet Time Topoff and why should I use it? The Topoff feature

helps ensure the batteries have enough charge to last (i.e., prevent the inverter from shutting down from a low battery condition) through the entire Quiet Time period. When the Topoff feature is enabled by setting a time, the battery voltage (or battery SOC¹) is monitored just before the start of Quiet Time; and if required, the generator will automatically start to charge the batteries. This Quiet Time Topoff menu allows you to set a time at which the generator will autostart before Quiet Time starts. This applies whenever the start parameters are close to starting the generator at the start of Quiet Time. If the battery voltage is within 0.3 volts² or less of reaching the 04A Gen Run VDC start parameter, the generator will autostart. The Quiet Time Topoff feature will also autostart the generator if the battery’s SOC is within 4% or less of reaching the 04D Gen Run SOC start parameter¹.

Scenario example (Topoff based on battery voltage): The 04A Gen

Run VDC menu is set to start at 11.5 VDC, Quiet Time is set to start at

10PM, and the Quiet Time Topoff setting is 60 min. At 9PM, the battery voltage reaches 11.8 VDC; because the Quiet Time Topoff feature is enabled (60 min.), the generator autostarts to allow the batteries to charge for 60 minutes before Quiet Time turns the generator off.

Scenario example (Topoff based on battery SOC¹): The 04D Gen Run

SOC menu is set to start at 60%, Quiet Time is set to start at 10PM, and

the Quiet Time Topoff setting is 120 min. At 8PM, the battery SOC reaches 64%; because the Quiet Time Topoff feature is enabled (120 min.), the generator autostarts to allow the batteries to charge for 120 minutes before Quiet Time turns the generator off.

Quiet Time is used when there are park

Note¹: Generator autostarting based on Quiet Time Topoff using battery

SOC (State of Charge) parameters requires the optional Battery Monitor Kit (ME-BMK or ME-BMK-NS) to be installed and enabled.

Note²: This voltage is scaled depending on your battery system; ≤0.3 for

12-volt systems, ≤0.6 for 24-volt systems, and ≤1.2 for 48-volt systems.

Page 80

7.0 Using an AGS Module

Where should I set Quiet Time Topoff? Normally, setting Quiet Time Topoff

to 30 or 60 minutes is a good idea. In cases where the DC or inverter loads are unusually high or the SOC autostart setting is low—which may cause the batteries to be heavily discharged during the Quiet Time period—increase Quiet Time Topoff to 90 or 120 minutes; this ensures the batteries receive the maximum charge time before Quiet Time shuts the generator off.

Info: When the generator starts on Quiet Time Topoff, it will continue

running until it reaches the Quiet Time start parameter even if the VDC or SOC autostop parameter is reached.

SETUP: 04H Gen Exercise Menu

This menu allows the generator to run (or “exercise”) after it has not been operated for a period of time. The generator is automatically started at a pre-selected time whenever it exceeds a set number of days without running. Once the start command is initiated, the generator starts and runs to help it remain operational and to allow the generator’s starting battery to be charged.

Info: The ME-ARC contains a real time clock that must be set for

proper operation of the SETUP: 04H Gen Exercise menu feature.

• Set Gen Exercise Days – This menu sets the maximum number of days

the generator is allowed to sit without running. If the generator has not run in this number of days, the exercise parameters will start the generator. The Set Gen Exercise Days setting must be between 1-255 days in order to enable the Gen Exercise feature.

Default setting: Set Gen Exercise Days = OFF Range: OFF, 1-255 Days

• Set Exercise Run Hour – Set the hour the generator will start.

• Set Exercise Run Minute – Set the minute the generator will start.

• Set Exercise Run AM-PM – Set AM-PM when the generator starts.

• Set Exercise Run Time – Set how long the generator will run for

the exercise period.

Default setting: Set Exercise Run Time = 1.0 Hrs Range: 0.0-25.5 Hrs

Why should I use the Gen Exercise feature? Most generators are very

dependable and provide years of service if properly maintained. Exercising your generator is one of the most overlooked aspects of routine maintenance, yet its the simplest to perform. Regularly exercising your generator keeps engine seals and components lubricated, prevents oxidation of electrical contacts, uses up fuel before it deteriorates, heats up the generator windings to eliminate moisture buildup, helps ensure the generator’s starting battery is maintained at an optimal state of charge, and, in general, helps provide reliable engine starting. If long periods of time elapse without using your generator (remains connected to external AC power), or if you only use your generator a few days out of the year, enabling the Gen Exercise feature is recommended. However, if you run your generator frequently throughout the year, you may not need to use the Gen Exercise feature.

How often and how long should I exercise my generator? To maximize

reliability and minimize repairs, it is important to exercise your generator at least once a month. This applies to both gas and diesel generators. When generators sit unused for as little as 30 days moisture can build up, and may damage your generator. Also, the fuel in gasoline-powered generators can

Page 81

7.0 Using an AGS Module

begin to break down into gums and varnishes that clog the fuel system. Fuel varnishing results in hard starting and surging—a surging generator may not settle at a stable operating speed. Always check with your generator’s manufacturer to determine how to properly exercise your generator. Generally,

it is recommended that you run the generator every month for two hours

under at least half the rated load. For example, with a 5,000 watt generator, turn on a load(s) that is about 2,500 watts, and let it run continuously for two hours. It is always best to run the generator for longer periods of time rather than for multiple short periods.

How does this Gen Exercise feature work? The Gen Exercise feature

allows the generator to autostart at a pre-selected time whenever it has not run for a set number of days.

Once the Gen Exercise feature is enabled (by setting how many days to wait before exercising the gen under Set Gen Exercise Days), the generator will start and begin exercising only after two conditions are met. First, the generator must not have run for a set number of days (i.e., the Days Since Run timer value must be equal to or greater than the Gen Exercise Days setting). Second, the generator’s exercise time of day (i.e., Exercise Run Hour/ Minute/AM-PM settings) must occur.

Info: When the generator starts and runs based on the gen exercise

criteria, the generator power passes thru the inverter to the inverter loads — if the inverter is enabled to accept AC power on its input— and also charges the inverter batteries (if the charger is enabled).

Info: The Gen Exercise feature identiﬁ es the number of days since

the generator has last run by using the Days Since Run timer which is shown under the METER: 03E Since Gen Run display.

Example of a Gen Exercise Scenario:

Under SETUP: 04H Gen Exercise Menu, set to: Set Gen Exercise Days = 3, Set Gen Exercise Run Hour, Minute and AM-PM = 8:30A, Set Gen Exercise Run Time = 1.0 Hrs Under CTRL: 03 Gen Control, set to AUTO.

First required condition: The Days Since Run timer must have accumu-

lated up to at least three days (Set Gen Exercise Days = 3). On Day 1, the generator was manually started and stopped at 2:00PM. The stop time (2:00 PM) is the starting point for the Days Since Run timer to begin counting days—the Days Since Run timer displays “0 days”. On Day 2 at 2:00 PM, 24 hours have accumulated since the generator has last run—the Days Since Run timer displays “1 day”. On Day 3 at 2:00 PM, 48 hours have accumulated since the generator last ran—the Days Since Run timer displays “2 days”. On Day 4 (third day since the generator was manually started) at 2:00PM, 72 hours (or three days) have now accumulated since the generator has last run—the Days Since Run timer now displays “3 days”. The ﬁ rst required condition—which is how many days must pass before the generator hasn’t run—has been met.

Second required condition: The remote clock must now go to 8:30 AM

(Set Gen Exercise Run Hour, Minute, and AM-PM = 8:30A) before the gen- erator can autostart. On Day 5 at 8:30AM (Days Since Run timer displays “3 days”), the second required condition is met and the generator automatically starts and runs for one hour (Set Gen Exercise Run Time = 1.0 Hrs).

Page 82

7.0 Using an AGS Module

SETUP: 04I Gen Warm-up Time Menu

This menu allows the generator to run (i.e., warm up) before it connects to the inverter/charger, or powers the battery charger and any pass-thru loads. Most generators need to warm up before a load is supplied.

• Set Gen Warm-up Time – This setting is the amount of time the gen-

erator is allowed to warm up before connecting to the inverter/charger.

Default setting: Set Gen Warm-up Time = 60 sec. Range: 0-127 Seconds, 1-127 Minutes

Where should I set Gen Warm-up Time?

manufacturer. Typically, smaller generators (~2-3KW) need at least 60 seconds before applying a load; larger generators require a longer warm-up time.

SETUP: 04J Gen Cooldown Time

This menu allows the generator to continue to run after it disconnects from the inverter/charger and prior to autostopping (i.e., cooldown). Allowing the generator to cool down after the load is disconnected helps to prolong generator engine life.

• Set Gen Cooldown Time – This setting is the amount of time the genera-

tor is allowed to cool down after it disconnects from the inverter/charger.

Default setting: Set Gen Cooldown Time = 60 sec. Range: 0-127 Seconds, 1-127 Minutes

Where should I set Gen Cooldown Time? Check with your generator

manufacturer. Most generators need at least 60 seconds to cool down after being disconnected from a load.

Info: The warm-up and cooldown features prevent the generator

from connecting to the inverter’s AC input. Since the inverter has only a single-source input, it cannot distinguish between grid or generator input. So, during warm-up or cooldown, the inverter will prevent any AC input from connecting. When either warm-up or cooldown is activated, it will disconnect any AC source connected to the inverter’s AC input (i.e., grid or generator) until the time period (warm-up or cooldown) is over.

Check with your generator

7.2 ME-AGS-N Functional Tests

Once you have used the ME-ARC to establish all the autostart/autostop settings you need, perform the following tests to verify that the AGS system is functioning correctly and there is communication between the remote/inverter and the ME-AGS-N.

7.2.1 Remote to Generator Communication Test

This section describes using the ME-ARC remote to start the generator and to determine the current AGS status.

7.2.1.1 Determining AGS Status

Use your remote control to determine the AGS’s status by pressing the METER button until the bottom line displays “01 DC Meters”, rotate the SELECT knob to the 03 AGS Meters menu, and then press the SELECT knob (top line shows 03A AGS Status and the bottom line displays the current status of the AGS, i.e., Ready). An AGS status of Off or Ready indicates the remote/inverter is correctly communicating with the AGS. If the AGS status displayed is not Off or Ready, then refer to Section 7.8.2 “Resolving Operational Statuses” or Section

7.8.3 “ME-AGS-N Faults using your Remote” for assistance before continuing.

Page 83

7.0 Using an AGS Module

7.2.1.2 Starting the Generator from the Remote

To conﬁ rm that the generator will turn on and run from the remote, ﬁ rst ensure the AGS status is Off or Ready (see Section 7.2.1.1). Then:

1. Press the CTRL button, and then rotate the SELECT knob to the 03 Gen

Control menu.

2. Press the SELECT knob, and then rotate it to the ON setting.

3. Press the SELECT knob to activate the generator test.

Once the generator starts, it should run until you change the 03 Gen Control menu to OFF (before turning off). After two minutes, view the STATUS LED and ensure it turns solid green (a solid green STATUS LED means the generator has started successfully and is providing the gen run sense signal to the AGS module).

Note: If the generator attempted to start but did not run, continue to wait,

the AGS will attempt to start the generator three more times. If your AGS/generator system started (may attempt autostart x4), ran, and

the STATUS LED came on and stayed on (not blinking), then the wiring from the AGS to the generator is correct. You are now ready to enable the AGS by setting the 03 Gen Control setting in your remote to AUTO (see Section 7.3.1).

Info: The AGS attempts to start the generator four times. If after

four attempts the generator fails to start, the STATUS LED turns red—indicating a fault.

If a generator fault displays or the AGS module’s STATUS LED shows a fault condition (solid red LED indication), refer to Section 7.8 for assistance.

7.3 ME-AGS-N Operation/Monitoring

This section provides the menus under the ME-ARC’s CTRL, METER, and TECH buttons that determine how to control and operate the generator. The section also includes menus that are used to help monitor the AGS and the generator’s starting and running conditions.

7.3.1 Controlling the AGS

The AGS uses the CTRL: 03 Gen Control menu to activate the generator either manually or automatically. Press the CTRL button on the ME-ARC remote and rotate the SELECT knob to the 03 Gen Control menu.

CTRL: 03 Gen Control

This menu is used to manually turn the connected generator on and off, or to select the AUTO feature which enables the active generator autostart and autostop settings to control the connected generator. Available options are:

OFF: The OFF selection turns the generator off if it is running from either a

manual “on” command or an autostart command. When OFF is selected, the AGS is prevented from starting the generator automatically (default).

Info: When OFF is selected, the AGS turns off immediately without

any cooldown time (if set).

Info: If DC power is lost to the remote or to the inverter system,

this menu resets to the default OFF position for safety.

Info: If the generator is manually started from the generator con-

trol panel or a generator remote panel, selecting OFF may not shut down the generator.

Page 84

7.0 Using an AGS Module

ON: The ON selection manually starts the generator by sending a “start”

command from the AGS module. Once the generator is started, it must be manually stopped, either from an external stop switch or by selecting OFF from the 03 Gen Control menu, which sends a “stop” command from the AGS module.

Info: When “ON” is selected, the Magnum inverter will not attempt to

accept the generator AC voltage until the warm-up period is satisﬁ ed.

Info: You can manually start the generator and have it automati-

cally stop by selecting ON from the 03 Gen Control menu, and then changing the selection to AUTO to automatically stop the generator. When AUTO is selected after the generator has been manually started, it displays the AGS status as “Start VDC” and uses the stop setting in the SETUP button’s 04A Gen Run VDC menu (even if not active) or the 04F Max Gen Run Time menu, whichever occurs ﬁ rst. This is useful if you want to make sure the generator starts before you leave; the Max Gen Run Time setting ensures the generator does not run longer than required.

AUTO: This selection uses the settings from the SETUP button’s 04 AGS Setup

menus to automatically start and stop the generator. Refer to the 04 AGS Setup menus in Section 7.1 to set the start and stop parameters for the generator.

7.3.2 Monitoring the AGS

The ME-ARC remote’s METER and TECH buttons have additional menus that are helpful for the proper operation and monitoring of your AGS system.

7.3.2.1 ME-ARC Remote’s AGS METER Button

Press the ME-ARC remote’s METER button, rotate the SELECT knob to the 03 AGS Meter menu, and then press the SELECT knob to access the AGS Meter

read-only menus. Rotate the SELECT knob to view the various AGS meters.

METER: 03A AGS Status Menu

This read-only menu displays the AGS’s current status. There are 26 different status messages that can display to identify what state the AGS is currently in—only one displays at any one time (refer also to Figure 7-2).

Available statuses are (see Tables 7-2 thru 7-4 for information on each):

• AC In

• Gen Cooldown

• Gen Warm-up

• Manual Run

• No Comm

• Off

• Quiet Time

• Ready

• Start Amp

• Start Exercise

• Start SOC

• Start Temp

• Start Test

• Start Time

• Start Topoff

• Start VDC

• Gen Run Fault

• Fault Amp

• Fault Exercise

• Fault SOC

• Fault Temp

• Fault Test

• Fault Time

• Fault Topoff

• Fault VDC

• Fault MaxRn

Info: This menu is important when determining if the AGS is work-

ing correctly, or for troubleshooting an AGS installation. For any fault mode displayed in the status menu, refer to Section 7.7.3 in this manual.

Page 85

7.0 Using an AGS Module

METER: 03B DC Volts-AGS Menu

This read-only menu displays the DC voltage measured at Terminals #3 and #4 of the AGS module. This menu is useful in setting up the voltage start for the AGS, and for troubleshooting its operation.

Info: The DC voltage reading in this menu may vary from the

DC voltage readings in the METER button’s 01A DC Volts and 04C DC Volts-BMK menu items. When troubleshooting, read the appropriate related meter for each device. When troubleshooting the AGS, use the 03B DC Volts-AGS menu for veriﬁ cation and testing purposes.

METER: 03C Gen Run Time Menu

This read-only menu displays the length of time the generator has been running since it was autostarted by the AGS. This helps determine how long the generator has been running in Auto mode if you were not present when it started. This menu is enabled when CTRL: 03 Gen Control is set to AUTO, but does not display run time when the generator has been manually started. Cooldown and warm-up times are not included in the gen run time display.

Info: The Gen Run Time menu’s timer is started when the gen run

sense voltage/signal is correct and qualiﬁ ed at the AGS module. It is not considered qualiﬁ ed until after a full start attempt and the Gen Warm-up Time setting is satisﬁ ed. Cooldown and warm-up times are not included in the gen run time display. Total generator run time = Gen Run Time + Gen Warm-up Time + Gen Cooldown.

Info: The times in this display are shown in tenths of an hour (0.0

hrs., 0.1 hrs., etc.,)—thus, 0.1 hrs. = 6 minutes.

Info: The Gen Run Time display resets to 0.0 each time the gen-

erator is autostopped. This meter is not designed to replace the hour meter for total hours the generator has run.

Info: This display is used by the SETUP: 04F Max Gen Run Time

menu to determine the generator’s maximum run time when started automatically.

METER: 03D AGS Temp Menu

This read-only menu displays the temperature of the AGS remote temp sensor (included with AGS, but use optional), and is helpful in determining its proper placement and operation. This temperature value can be displayed in either Fahrenheit or Celsius depending on the SETUP: 01E Temp Display setting. Use this menu to change the temperature format, if required.

METER: 03E Since Gen Run (Days) Menu

This read-only menu displays the number of days since the generator has last run. This is useful in determining if the start and stop settings are set up correctly. This timer begins once the CTRL: 03 Gen Control menu is set to AUTO, and then counts by one for every 24-hour period the generator does not start. The Days Since Run timer resets any time the generator starts, which could be either by autostarting the generator (including from a previous exercise run), or manually starting the generator.

Info: When the DIP switch inside the AGS is set to “2-Wire Standby

Mode”, if you do not use the ME-ARC to manually turn the generator on, the Days Since Run timer will not be reset to zero.

7.4 Enabling the ME-AGS-N

Before the AGS can begin operating/monitoring for an autostart condition (using active AGS settings in your ME-ARC remote control), it must be enabled.

To enable the AGS:

1. Press the CTRL button on the ME-ARC remote, and then rotate the SELECT knob to the 03 Gen Control menu.

2. Press the SELECT knob. The Set Gen Control screen displays with the current gen control setting and an arrow to the right.

3. Turn the SELECT knob to the AUTO setting.

4. Press the SELECT knob again to select this setting. The selection arrow appears to the right of the screen.

The AGS is now ready to automatically start/stop the generator once an autostart condition is satisﬁ ed.

Note: If power is lost to your remote, the AGS control setting will return to the

default OFF setting. Once power is restored, you must enable the AGS again.

7.5 Starting and Stopping the Generator

The generator can be manually started/stopped, as well as autostarted/autostopped using the available settings from your ME-ARC.

To autostart/autostop the generator:

In order for the generator to autostart/autostop, one or more of the following autostart/autostop conditions must be pre-set (see Section 7.1):

Autostart Conditions

• 04A Gen Run VDC (pp. 66-68)

• 04B Gen Run Time (p. 68)

• 04C Gen Run Amps (pp. 68-69)

• 04D Gen Run SOC (pp. 69-70)

• 04E Gen Run Temp (pp. 70-71)

• 04G Quiet Time (pp. 72-74)

• 04H Gen Run Exercise (pp. 74-75)

To manually start the generator:

7.7 ME-AGS-N Remote Status Messages

A status message may be an operational or fault message. Access the AGS status menu (METER button’s 03A AGS Status menu) to view the AGS’s current operating status. This menu is important when determining if the AGS is working correctly, or for troubleshooting an AGS installation.

7.7.1 AGS Remote Operational Statuses

Refer to Table 7-2 below for a brief description of the possible AGS operational statuses that may display (depending on your remote).

Table 7-2, AGS Remote Operational Statuses

STATUS DESCRIPTION

AC In The inverter/charger is connected to another source

such as a grid or an alternate generator, and is not controlled by the AGS. When AC In displays, the AGS is prevented or locked out from all autostarting conditions, except for when the generator needs to exercise—if enabled.

Gen Cooldown The autostop setting has been met in one of the gen-

erator autostart/autostop menus and the generator has been disconnected from the inverter/charger. However, the generator is still runs until the cooldown time is met (as per the SETUP: 04J Gen Cooldown Time setting).

Gen Warm-up The AGS is attempting to start the generator and a

time period has been set under the SETUP: 04I Gen Warm-up Time setting. Once the AGS status indicates “Warm-up”, the inverter/charger’s AC input ignores any incoming AC power. This prevents the inverter/charger from loading the generator during warm-up. Once the AGS has determined that the generator is running, the warm-up time setting must be met before the generator can connect to the inverter/charger.

Manual Run The generator was started manually from a start/stop

switch directly connected to the generator, or from the CTRL: 03 Gen Control menu.

Note: The AGS determines that the generator has been manually turned

on by sensing a gen run sense voltage to Terminal #2 on the AGS’s 8-port terminal block. However, if the Gen Type DIP switch is set to “2-Wire Standby” (which doesn’t require a gen run sense voltage), manually turning the generator on displays a status of AC In rather than Manual Run.

No Comm The AGS is not communicating with the inverter/re-

mote. This is a normal status if there is no AGS-N (Network

version) connected in the system. If an AGS is installed, then refer to Section 7.8.2 “Re-

solving Operational Statuses” for assistance.

Off The CTRL: 03 Gen Control menu is set to OFF. This set-

ting will not allow the AGS to autostart the generator.

Page 93

7.0 Using an AGS Module

Table 7-2, AGS Remote Operational Statuses (cont.)

STATUS DESCRIPTION

Quiet Time The AGS has entered Quiet Time per the SETUP: 04G

Quiet Time setting.

Note: The generator will not autostart during Quiet Time.

Ready The CTRL: 03 Gen Control menu is set to AUTO, and the

AGS is ready to automatically start the generator based on the active autostart settings under the SETUP: 04 AGS Setup menu.

7.7.2 AGS Remote Start Statuses

The following “Start” statuses identify the condition that autostarted the generator. If you determine that the autostart condition occurred sooner than expected (or didn’t want this autostart condition), refer to the Setup section for your speciﬁ c remote to change (or defeat) the autostart setting.

Table 7-3, AGS Remote Start Statuses

STATUS DESCRIPTION

Start Amp The generator has started based on the SETUP: 04C

Gen Run Amps setting.

Start Exercise The generator has started based on the SETUP: 04H

Gen Exercise setting.

Start SOC The generator has started based on the SETUP: 04D

Gen Run SOC setting.

Start Temp The generator has started based on the SETUP: 04E

Gen Run Temp setting.

Start Test The AGS is in Test mode. Test mode may be started

from the TEST button located on the AGS,

Start Time The generator has started based on the SETUP: 04B

Gen Run Time setting.

Start Topoff The generator has started based on the SETUP: 04G

Quiet Time Topoff Time setting.

Start VDC The generator has started based on SETUP: 04A Gen

Run VDC setting.

7.7.3 AGS Remote Fault Statuses

The following “Fault” statuses indicate that the generator wasn’t able to start based on an expected autostart condition. Refer to Section 7.8.3 “Resolving AGS Faults Using the Remote” for help in diagnosing the problem.

Table 7-4, AGS Remote Fault Statuses

STATUS DESCRIPTION

Gen Run Fault The generator successfully started and ran for more than

two minutes, but unexpectedly stopped before the AGS could automatically stop the generator.

Fault Amp The generator failed to start in Start Amps mode. Fault Exercise The generator failed to start in Start Exercise mode.

Fault SOC The generator failed to start in Start SOC mode. Fault Temp The generator failed to start in Start Temp mode. Fault Test The generator failed to start in Test mode.

Fault Time The generator failed to start in Start Time mode. Fault Topoff The generator failed to start in Start Topoff mode. Fault VDC The generator failed to start in Start VDC mode. Fault MaxRn The generator turned off because the SETUP: 04F Max

Gen Run Time setting had been met. This fault can occur when: 1) an autostop parameter has been met, but it did not stop the generator, or, 2) the autostop condition exceeded the Max Gen Run Time setting.

7.7.4 AGS General Notes

• If a fault condition occurs, select the OFF setting from the 03 Gen Control

menu. If the problem persists, refer to Section 7.8 “ME-AGS-N Remote Troubleshooting” in this manual.

• When the gen control setting in the remote is in the OFF position, all

generator autostart functions are disabled and the AGS module’s STATUS indicator will also be off.

• When AGS control is set to AUTO, and an autostart condition occurs, it

attempts an automatic generator start. This is done by closing its internal relays (based on the Gen Type selection) to control the starter – much like a person does when manually starting the generator. The starter is turned on for short periods of time and then turned off. If the AGS determines that the engine has started while cranking (STATUS indicator lights solid green), the starter is turned off after a short delay. If the engine does not start, another attempt is made to turn on the starter after a long delay period. This is repeated until the generator starts or until all its start attempts are reached, which causes the AGS to go into a fault condition (indicated by a blinking FAULT indication on the remote and a solid red STATUS indicator on the AGS module).

• If using the temperature autostart feature in an RV coach, set the air

conditioner thermostat slightly less than the setting (04E Gen Run Temp menu). If using two air conditioners, it is suggested that the second air conditioner thermostat be set 2° to 5° higher than the ﬁ rst air conditioner. This staggered setting allows the ﬁ rst air conditioner to start and run in an effort to keep the coach cool. If the temperature continues to rise inside the coach, the second air conditioner will turn on.

• When the generator starts successfully, the STATUS indicator on the AGS

module will turn solid green. The generator will run until an autostop condition is reached or until it is manually turned off; at which time a stop signal will be sent to the generator.

• If the generator is running when the AGS module’s TEST button is pressed,

the generator will stop and then start again. The generator will then run for approximately 30-60 seconds before shutting off.

• There is a delay before the AGS attempts to start the generator. The

delay is adjustable on volts and amps (04A Gen Run VDC and 04C Gen Run Amps settings). There is no delay if the AGS attempts to start the generator when the temperature around the remote temp sensor rises to the 04E Gen Run Temp Start setting.

• Several autostart/autostop settings can be active at once. However, once

an autostart condition becomes active, all other autostart conditions are ignored until the speciﬁ c condition that caused the generator to start (e.g., Start Gen AC Amps) is satisﬁ ed by its autostop condition (e.g., Stop Gen AC Amps). Once the generator has completed this autostart/ autostop cycle, the AGS immediately begins to monitor for any active autostart/autostop settings again.

7.8 ME-AGS-N Remote Troubleshooting

This section assists you in using your remote control to identify a fault, and to resolve an abnormal operational condition detected within your AGS system.

7.8.1 AGS Fault Message Screen

When an AGS fault is detected, and the remote’s FAULT LED comes on, the fault status is displayed on the LCD screen. Figure 7-5 is an example of how fault messages appear on the ME-ARC remote. Use the remote’s LCD screen and the information in this section to identify and correct the issue. The FAULT LED blinks and the fault alternates with the inverter/charger status.

7.8.2 Resolving Operational Statuses

The following operational statuses can display on your ME-ARC, and some may indicate an abnormal condition. This section provides additional information and assistance to resolve these statuses (if needed).

• AC In – This is a normal status when the input to the inverter/charger is

connected to an AC source such as utility/grid power, or to an alternate generator that may not be controlled by the AGS.

Remedy: The AC In status prevents the AGS from autostarting. To

enable the AGS to autostart the generator, remove any AC power connected to the input of the inverter/charger.

• No Comm – This is a normal status if there is no AGS installed. If an

AGS is installed, use the information below to determine the remedy.

Remedy: If an AGS is installed, then follow these steps:

1. Ensure the green READY indicator on the AGS module is on (blinking or solid) to indicate that the AGS module is getting power.

2. Ensure the communications cable is connected from the Network port on the Magnum inverter to the NETWORK port on the ME-AGS-N.

3. Ensure you have the correct communications cable.

Page 97

7.0 Using an AGS Module

7.8.3 Resolving AGS Faults using the Remote

Should an AGS fault occur, use your ME-ARC remote and the information in this section to resolve the issue.

• Gen Run Fault – The generator successfully started and ran for more

than two minutes, but the generator unexpectedly stopped by itself before the active AGS autostop condition was ﬁ nished.

Info: The AGS module determines the generator is running by

monitoring the gen run sense voltage/signal. When this gen run sense voltage/signal is no longer available, the AGS thinks the gen is off or has stopped.

Info: Gen run fault detection is not active if the generator is manu-

ally started.

Remedy:

A) If the generator is still running: Conﬁ rm you are getting the cor- rect gen run sense signal to the AGS module. For assistance, refer to your ME-AGS-N owner’s manual.

B) If the generator is not running: Check the generator for fault codes and adequate fuel. If neither is an issue, check the generator’s owner’s manual for troubleshooting tips to determine why it may have shut down on its own.

For the eight faults listed below, refer to the Remedy immediately following.

• Fault Amp – The generator failed to autostart and run per the 04C Gen

Run Amps menu’s start parameters.

• Fault Exercise – The generator failed to autostart and run per the 04H

Gen Exercise menu’s start parameters.

• Fault SOC – The generator failed to autostart and run per the 04D Gen

Run SOC menu’s start parameters.

• Fault Temp – The generator failed to autostart and run per the 04 Start

Temp F menu’s (ME-RC) or the 04E Gen Run Temp menu’s (ME-ARC and

ME-RTR) start parameters.

• Fault Test – The generator failed to autostart and run after the red

TEST button is pressed on the AGS module.

Note: The ME-ARC can be set to manually turn the generator on and off,

which can be used to test the generator wiring to the AGS.

• Fault Time – The generator failed to autostart and run per the 04B Gen

Run Time menu’s start parameters.

• Fault Topoff – The generator failed to autostart and run per the 04G

Quiet Time Topoff start parameters.

• Fault VDC – The generator failed to autostart and run per the 04A Gen

Run VDC menu’s start parameters.

Remedy: One of the above fault messages may display on the ARC

remote when: A. The AGS attempts to start the generator four times, but the gen

failed to start and run per the speciﬁ c autostart parameters; or, B. The generator started, but did not provide the correct gen run

sense signal to the AGS module. For either scenario, refer to your ME-AGS-N owner’s manual.

Page 98

7.0 Using an AGS Module

• Fault MaxRn – The generator has turned off because the gen run

time—after autostarting—has exceeded the SETUP: 04F Max Gen Run Time setting.

Info: The Max Gen Run Time menu uses the SETUP: 04B Gen Run

Time display to determine the generator’s run time. Cooldown and warm-up times are not included in the Gen Run Time display.

Remedy: Conﬁ rm that all the autostop parameters that are active

or enabled can be satisﬁ ed before the SETUP: 04F Max Gen Run Time setting is reached.

• If using the SETUP: 04A Gen Run VDC menu’s parameters: – with a battery voltage setting to autostop, ensure the autostop voltage is less than the temperature-compensated absorb charge voltage.

– with the “Float” setting to autostop, ensure the time that the

charger is in the Bulk Charge and Absorb Charge¹ stages is

shorter than the 04F Max Gen Run Time setting. Refer to the SETUP: 04A Gen Run VDC section for additional

information on this setting.

• If using SETUP: 04B Gen Run Time, conﬁ rm you have not set the total run time (start time to the stop time) longer than the SETUP: 04F Max Gen Run Time setting.

• If using SETUP: 04C Gen Run Amps, conﬁ rm the inverter load(s) that is used to determine the Stop Gen AC Amps setting is not required to run longer than the SETUP: 04F Max Gen Run Time setting.

• If using SETUP: 04D Gen Run SOC, conﬁ rm that the METER: 04A BMK SOC reading is not “Think’n”, but shows an actual percentage reading on the display (i.e., 85%), and the Stop

Gen SOC setting can be satisﬁ ed before the SETUP: 04F Max Gen Run Time setting is reached.

• If using SETUP: 04E Gen Run Temp, the temperature around the remote temperature sensor has not reached the Gen Run Temp setting. You need to either lower the Gen Run Temp Start setting, determine how to cool the area (remote temp sensor location) to below the Gen Run Temp Start setting before the

04F Max Gen Run Time setting is reached, or increase the Max Gen Run Time setting.

Lastly, conﬁ rm that your warm-up and/or cooldown time when add- ed to your autostop condition does not exceed the SETUP: 04F Max Gen Run Time setting.

Info: Beginning with Revision 5.2 of the ME-AGS-N, the Max Gen Run

Time setting can be defeated. In some cases, it may be appropriate

to set the Max Gen Run Time setting to OFF. However, this feature is mainly provided as a safety feature to ensure the generator doesn’t run longer than the time it takes to reach the autostop conditions or to expend the generator’s fuel capacity, whichever occurs ﬁ rst – take this into consideration if this setting is defeated.

Note¹: Several conditions determine the length of time that the charger is in the Absorb Charge stage. Ensure the SETUP: 03E Absorb Done (Time, Amps, or SOC) setting—determines when the Absorb Charge stage is complete and enters the Float stage—is taken into account when setting the 04F Max Gen Run Time setting.

7.8.4 How to Clear AGS Faults

Go to the CTRL: 03 Gen Control menu, and then select OFF.

Note: After the fault clears and the reason for the fault is determined, be

sure to re-enable the AGS to autostart. Go to the CTRL: 03 Gen Control menu and select AUTO. Refer to Figure 7-2.

Once the fault is cleared and the reason for the fault is determined, you should re-enable the AGS to see if the fault returns, or test the AGS/generator system by performing the AGS functional test for your remote (see Section 7.2).

7.8.4 How to Clear AGS Fault History

Go to the TECH button’s 04 Fault History menu, press the SELECT knob, and then turn the knob until the 04C Clear Faults screen appears.

At the 04C Clear Faults screen, press and hold the SELECT knob until the “5.0 to 0.0 second” screen countdown is ﬁ nished and the screen displays “HISTORY CLEARED”.

Info: Be sure you do not want the fault history for either device

(inverter or AGS). Once it has been cleared, it cannot be retrieved.

This section discusses how to set up and monitor Magnum’s Battery Monitor Kit (ME-BMK) using the ME-ARC remote. It also covers other BMK menu options that are available using this remote. Use the mini-index below to direct you to the appropriate section.

8.1 BMK Setup p. 94

8.2 Monitoring the BMK p. 95

8.3 BMK Menu Maps p. 98

8.1 Setting Up the BMK

Use the ARC remote’s SETUP button to establish the charge efﬁ ciency and amp- hour size settings for your battery monitor (ME-BMK).

SETUP: 05 BMK Setup

This section provides information about charge efﬁ ciency and how to manually access/adjust this setting and the amp-hour setting.

• 05A Charge Eff – This menu enables you to manually access and adjust

your battery’s charge efﬁ ciency. The charge efﬁ ciency setting allows the battery monitor to calculate the battery’s charge efﬁ ciency. Normally, the ME-BMK battery monitor automatically calculates the battery’s efﬁ ciency.

Default setting: Auto Range: Auto, 50%-97%

Info: The factory default Auto setting allows the charging efﬁ ciency

to be automatically calculated. In most circumstances, the Auto setting will determine the best charge efﬁ ciency.

CAUTION: If you do not know your battery’s charging efﬁ ciency,

leave it at the factory default setting. If the setting is manually set but incorrect, the state-of-charge (SOC) information will become more inaccurate with every charge.

What is charge efﬁ ciency? When a certain amount of energy is removed or

discharged from the battery, this removed energy will need to be returned to keep the batteries at a 100% state-of-charge. As batteries are being charged, they lose energy—either in the form of heat, or while gassing. This loss of energy while charging means the battery will not be fully charged if you only return the current that was removed. To compensate for the battery’s inefﬁ ciencies while charging, a charge efﬁ ciency setting is provided. The charge efﬁ ciency setting compensates the AH I/O (Amp-Hours In/Out) reading by ensuring the AHs returned to the battery are greater than the AHs removed.

For example, if your AH I/O display reads 000 and you begin powering a 25-amp load for two hours, the display will show -050. This indicates that you have discharged 50 AHs (2 x 25) from the battery. If the charge efﬁ ciency setting is set to 95%, then as you begin charging and return 50 AHs, the AH I/O reading will be less than zero, indicating that the AHs removed have not been fully returned. The 95% charge efﬁ ciency setting requires 52.5 AHs (50/95) to be returned before the AH I/O returns to 0.

How do I access the charge efﬁ ciency setting? Press the ARC’s SETUP

button, rotate the SELECT knob to the 05 BMK Setup menu, and then press the SELECT knob again to access the 05A Charge Eff menu item (see Figure 8-1).
