1.3 Function Descriptions

1.3.1 Rectifier Control

Rectifiers are automatically controlled by the ACU+ Controller. The ACU+ Controller provides an Energy Optimization Mode function. Energy Optimization permits an installation to only operate rectifiers as needed to maintain the load and keep batteries in a fully charged condition. As load increases, Energy Optimization turns on additional rectifiers as needed to maintain the load. As load decreases, Energy Optimization places rectifiers in standby to conserve energy usage. Rectifiers which are always operating to maintain any load requirements are cycled through the group of rectifiers controlled by this feature to provide uniform operating times for each rectifier.

1.3.2 Converter Control

Converters are automatically controlled by the ACU+ Controller.

1.3.3 System Components Monitoring and System Alarms Generation

The ACU+ Controller monitors the components comprising the system (such as the rectifiers, converters, and supervisory modules) and generates alarms if a fault condition occurs. The ACU+ Controller also maintains an alarm history log.

The available system alarms are programmed with an Alarm Severity Level. Each Alarm Severity Level has different visual/audible alarm attributes. Available Alarm Severity Levels and their attributes are listed in Table 1.

Table 1

Alarm Severity Levels

The alarm indicator turns OFF if the fault(s) that triggered the alarm clears. The audible alarm can be silenced by pressing any key on the ACU+ Controller local interface pad.

The audible alarm is also silenced if the fault(s) that triggered the alarm clears. An audible alarm cutoff feature can be programmed that silences the audible alarm after a pre-set

programmable time period. The audible alarm can also be disabled.

The available system alarms can also be mapped to alarm relays (located on ACU+ interface boards) that can be wired to external alarm circuits.

1.3.4 Operating Data Acquisition and Data Logs

The ACU+ Controller acquires and analyses real time data from the system’s components such as the rectifiers, converters, and supervisory modules.

The ACU+ Controller uses this data to process alarms and also records data in logs. The logs are viewed using the WEB Interface and consists of...

Alarm History Log: records 600 latest alarms. Data History Log: records 60000 latest history data. Control Log: records 500 latest control events. System Log: records 3000 latest system events. Diesel Test Log: records 500 latest diesel test results. Battery Test Log: up to twelve (12) battery discharge tests can be performed and recorded per year.

Note: Once maximum number of log entries is reached, new entries overwrite oldest entries.

Logs can be saved in the text (.txt) format.

Battery Charge Temperature Compensation

The ACU+ Controller can be programmed to automatically increase or decrease system output voltage to maintain battery float current as battery temperature decreases or increases, respectively. Battery life can be extended when an optimum charge voltage to the battery with respect to temperature is maintained. Temperature is monitored by a sensor mounted on the battery. See your power system documentation for temperature sensor information. You can also set High2, High1, and Low compensation temperature alarms.

Functional Description (See Figure 2): Battery charge temperature compensation adds a correction term, related to the temperature of the batteries, to the nominal value of the system voltage. The degree of regulation (TempComp Coeff), expressed in mV/°C/battery string, can be set per battery manufacturer recommendations.

To protect batteries and voltage-sensitive loads, compensation is automatically limited to a maximum of two volts (48V systems) or one volt (24 volt systems) above or below the nominal output level (float setting).

Temperature compensation will also clamp if the voltage reaches either the TEMP COMP MAX V setting or the TEMP COMP MIN V setting. This feature can also be disabled.

Temperature compensation is automatically disabled if communication between the Controller and all rectifiers is lost, a DC over or under voltage alarm activates, a low voltage disconnection occurs, manual mode is entered, or the system enters the boost or test modes.

Battery Equalize Charge and Battery Charge Current Limit

The ACU+ Controller can increase system output voltage for equalizing the charge on all battery cells of a conventional flooded cell battery, or for recharging the battery following a commercial power failure.

The charging function can be initiated cyclically (scheduled), automatically, or manually. Refer to the battery manufacturer's instructions for equalize charging instructions.

Functional Description (See Figure 3):

Start of Charging: When the battery charge current exceeds a preset value for 3 minutes or if the

calculated battery capacity has decreased to a preset value (after a commercial AC failure, for

example), the charging function of the ACU+ is activated. A charging signal is sent from the ACU+ to

the rectifiers to increase the voltage up to the battery charging level V

equalize

Battery Current Limitation: After a commercial AC failure or when some battery cells are

permanently damaged, the current to the batteries can be quite extensive. To avoid overheating or

further damages to the battery, the ACU+ limits the battery current to a preset level by limiting the

charging voltage of the rectifiers. Should the battery current still exceed a higher preset value, an

alarm is issued. End of Charging: When the charging current drops below a preset value, a defined prolonged

charging time is started before the charging is stopped and the voltage of the rectifiers return to the

float charging level (V

). For safety, there is a equalize charging limit time that stops the charging

nom

after a preset time.

Figure 3

Voltage Characteristics on Commercial AC Failure and Automatic Equalize Charging

High and Low Battery Temperature Alarms

The ACU+ Controller can monitor battery temperature via a temperature sensor mounted on a battery cell. Values for high battery temperature and low battery temperature alarms can then be programmed into the ACU+ Controller.

Battery Thermal Runaway Management (BTRM) Feature

You can designate a temperature sensor as the BTRM sensor. The BTRM sensor has High2 and High1 BTRM temperature alarm limits. If battery temperature exceeds the “BTRM Temp High2” setting, system voltage is lowered to the BTRM voltage setting. This feature can also be disabled.

Battery Discharge Test and Battery Test Logs

The ACU+ Controller can perform battery discharge tests to check the condition of the battery. There are (3) types of battery discharge tests.

Short Time Test Time Test Stable Current Test

A User can manually start a battery discharge test or program the ACU+ Controller to automatically start battery discharge tests at scheduled intervals (cyclic battery tests). During a battery discharge test, the ACU+ Controller controls the rectifiers output to place the entire load or partial load on the batteries. The ACU+ Controller monitors the discharge of the battery and saves the results in a battery test log.

Functional Description: For manual battery discharge tests as well as for cyclic battery discharge tests, the following parameters must be set: End Voltage, Test Time, and Battery Capacity Discharge Limit. See Figure 4.

Battery Discharge Test Sequence:

In time test modes, the output voltage of the rectifiers is reduced so that only the batteries power the

load. If the batteries fail, the rectifiers power the load. In stable current test mode, the output voltage of the rectifiers is reduced so that the batteries supply

the preset test current to the load. The battery test continues until one of the following occurs:

The preset test time, see Figure 4, expires. The battery has passed the test. The battery voltage drops below the preset end voltage level (V

) (Figure 4). The battery has not

end

passed the test and the test is interrupted. A battery test alarm is activated.

The battery capacity drops below the preset test end battery capacity. The battery has not passed

the test and the test is interrupted. A battery test alarm is activated.

After the battery discharge test, the output voltage of the rectifiers increase so that the rectifiers supply

the system and charge the batteries.

UM1M820BNA User Instructions Issue AH, March 4, 2013 Spec No. 1M820BNA (Model M820B) Spec No. 1M820DNA (Model M820D)

Battery LVD (Low Voltage Disconnect)

To prevent serious damage to the batteries during a commercial AC power failure, the batteries can be disconnected by voltage or time control.

The batteries are reconnected automatically when commercial AC power is restored and a predetermined DC voltage level is reached.

Voltage Controlled Disconnection: When the set voltage level is reached, the batteries are

disconnected. Time Controlled Disconnection: When the set time has elapsed, the batteries are disconnected.

Battery Capacity Prediction

The ACU+ can predict battery capacity.

Battery Block and Battery Midpoint Monitoring

The ACU+ can monitor battery blocks (12V blocks) or midpoint battery voltage of battery strings connected to the EIB assembly. An alarm is issued when either battery block voltage or battery midpoint voltage is abnormal.

Enhanced Battery Monitoring with SM-BRC

When connected to an SM-BRC, the ACU+ provides enhanced battery monitoring.

Thermal Runaway Detection and Management Functional Description: The system uses several control mechanisms to avoid thermal runaway.

First: During a short high rate discharge, the batteries will normally get hot. The ACU+ takes this into consideration. After completion of the discharge duty, the batteries are recharged with a limited current to avoid heating the batteries any further.

Second: The temperature of the batteries can be monitored, and the ACU+ sets the charge voltage appropriately, as previously described under Battery Charge Temperature Compensation.

Third: In addition to battery temperature compensation, if battery temperature rises above a set temperature limit, the system stops battery charging completely by lowering the output voltage to the “BTRM Voltage” setting. This allows the batteries to cool down. The system also provides alarm notification of this occurrence. Power supplied to customer equipment is not interrupted.

Fourth: The battery LVD circuits can be programmed to open (disconnect) if a high temperature event occurs (HTD – High Temperature Disconnect). The contactor(s) open when battery temperature rises above a programmable value and close again when battery temperature falls below another programmable value.

1.3.6 Intelligent Power Matching (Energy Optimization Mode)

1.3.7 Power Split Feature

The Power Split feature allows you to connect the power system controlled via the ACU+ to an existing DC power system instead of extending or completely replacing the existing DC power system.

The power system controlled via the ACU+ functions as a slave system to share load (split output) with the existing system (master system) that requires expansion. The ACU+ does not require communication with the master system’s Controller.

The Power Split feature provides for the sharing of total load in a controlled manner between the paralleled power systems.

When Power Split is programmed, the ACU+ adjusts rectifier output voltage per load demands to ensure proper sharing between the slave and master power systems. See Figure 5.

1.3.8 Diesel Management Feature

The Diesel Management feature is available when an SM-AC supervisory module is connected to the ACU+ Controller. The Diesel Management feature consists of a Diesel Test. The Diesel Test can be performed at specific intervals or a User can manually start the Diesel Test. The ACU+ records the test results.

1.3.9 PLC (Programmable Logic Controller) Function

The PLC function allows a User to create "control program lines" by combining equipment analog signals, parameters, and alarms in a sequence that controls equipment and/or operates relays.

Control program lines are created using the WEB Interface. See “4.8.6. PLC Sub-Menu”. Available logical components are:

1.3.10 Supervisory Module (SM Modules) Monitoring

Various devices (supervisory modules) can be connected to the ACU+ Controller to extend its monitoring capabilities.

1.3.11 Hybrid Control Function

Hybrid Control is designed for use in new installations or as an upgrade of existing sites powered by a diesel generator(s) when grid power is not available. The Hybrid Control is also applicable to sites with highly unreliable or frequently unavailable grid power connection. The primary power source is still considered to be the diesel generator(s).

Note: The Hybrid Control function requires a specific configuration. Hybrid Control menus will not

normally be displayed unless your ACU+ has been configured by Emerson for this function. Contact Emerson for a Hybrid Control configuration.

General

Hybrid Control allows the option of selecting one of the following: Fixed Daily Time based operation or Capacity Discharge based operation.

Systems, North America, Inc. Any copying, use, or disclosure of it without the written permission of Emerson Network Power, Energy Systems, North America, Inc. is strictly prohibited.

User Instructions UM1M820BNA Spec No. 1M820BNA (Model M820B) Issue AH, March 4, 2013 Spec No. 1M820DNA (Model M820D)

Fixed Daily Time based operation is intended to be used with a combination of AC powered active cooling (air conditioners) and DC powered cooling (heat exchangers, etc). The cycle period is synchronized to the 24hr day-night cycle. It makes optimum use of the different temperature conditions during the day and the night in order to facilitate Hybrid fuel saving operation.

Capacity Discharge based operation is intended for sites utilizing only DC powered cooling (heat exchangers, etc). The cycle period is determined by User selectable depth of discharge (DOD) of the batteries per cycle and associated recharge time. It provides optimum Hybrid fuel saving operation.

Operation from Grid Power is performed with both Fixed Daily Time and Capacity Discharge modes of operation. Grid power is always given priority when available.

As the two types of control are specific to the hardware configuration of the site, the Fixed Daily Time or Capacity Discharge is a User selectable option on installation.

Hybrid Operation Generator Control: Potential free relay contact output from the ACU+ interface board controls the start

and stop of the diesel generator. The signal is generated by the ACU+ Controller and operates according to the Hybrid software mode of operation. The control logic is as follows:

Energized output relay – Generator OFF. De-energized output relay – Generator ON.

This is a fail-safe logic to ensure generator operation in all cases where power or control to the relay is lost.

Further to that, the type of signal to the generator can be selected as N/O (Normally Open) or N/C (Normally Closed) by selecting the relevant output pins of the control relay.

Number of Generator Control Outputs: The ACU+ Hybrid software can control one or two generators. Each generator control is designated as DG1 or DG2 output. A User selectable menu will allow selecting DG1, DG2, or DG1 and DG2. When both are selected they will be alternatively used (two generator operation).

Diesel Fail Alarm: A diesel fail alarm will be generated if the Diesel Generator ON signal fails to bring the generator to operation and provide the system with AC power. Alarm will be triggered after 60 seconds (default value, settable) from ON signal. If two generator operations are selected simultaneously with the alarm, the second Diesel Generator ON signal will be activated.

Battery Fuse Trip Alarm: In the event of a Battery Fuse trip condition an alarm will be generated. Under Voltage Alarms:

Under Voltage Alarm 1: An Under Voltage Alarm 1 is set. If voltage decreases below this setting, an

alarm is raised. Under Voltage Alarm 2: An Under Voltage Alarm 2 is set. If voltage decreases below this setting, the

Diesel Generator is started and an alarm is raised.

LVD 1: Normal loads are disconnected. LVD 2: Priority loads are disconnected. Charge Voltage:

Figure 6

Charge Voltage

Equalize Charge: The battery will be recharged at equalize voltage. This is the voltage set in the initial phase of battery recharge. See Figure 6.

As the voltage limit is reached, the charge current is gradually reduced – effect known as current tail. When the current tail falls below a set of threshold levels, additional equalize charge time is added.

The equalize charge current tail threshold is settable from 0.01 to 0.05. Default setting is 0.02 (2A per 100Ah). The additional equalize charge time is settable from 0 hours to 7 hours (settable in minutes from 0 to 720), default setting is 4 hours. The duration of the equalize charge is determined as the time from the start of the recharge to the end of the additional time. (Maximum charge time, determined from the time charge starts, is settable in the range of 5-24h.)

The end of recharge is determined by a three (3) step approach:

Step1 - calculated battery capacity exceeds 90%. Calculation is performed by measurement of battery current and time, in Ah.

Step 2 - charge current tail threshold is reached.

Step 3 - additional charge time is added. Float Charge: Default float voltage is 54.0V at 20°C with a temperature compensation of -72mV per °C. If battery temperature exceeds 38°C, the charge voltage is reduced to 51V to reduce gassing and prevent

thermal runaway. The same is applicable as well for equalizing charge. Equalizing Charge: As the cyclic use does not ensure complete battery recharge after every cycle, an

equalizing charge cycle is added. The equalizing cycle will occur up to four times a month, settable for every 7 to 60 days intervals. Start date and time is settable. Equalizing charge time is 20 hours independent of discharge time setting. Equalizing charge is performed at equalize voltage until end of additional equalize time and thereafter at float voltage for the remaining time. Also see Figure 6.

Equalize charge independently settable 0-720 min (already set in equalize charge).

User Instructions UM1M820BNA Spec No. 1M820BNA (Model M820B) Issue AH, March 4, 2013 Spec No. 1M820DNA (Model M820D)

Early Termination of the Discharge Periods During discharge, over temperature and under voltage conditions will interrupt the discharge and

change the operation to charge – Diesel Generator ON. Over Temperature: The diesel generator will start and run for a period before it is stopped again. The run

time is User selectable in the range 30 to 120 minutes, default setting is 60 minutes. Temperature is referenced to cabinet/shelter ambient temperature sensor connected to the Controller, not battery temperature. Over temperature start can be disabled completely from User settings menu.

Under Voltage: The under voltage start is triggered by under voltage alarm 2 voltage settings. The diesel generator will start and run until the normal recharge cycle is due to finish depending on

selected mode of operation. Example for Fixed Daily Time: If the normal recharge cycle is from 7am until 7pm and under voltage has

started the diesel generator at 5:30am, the effective recharge will be from 5:30am until 7pm.

Example for Capacity Discharge: If this mode is selected, the recharge will terminate. Operation with Grid Power

Grid power is always prioritized when available. If grid power becomes available during battery discharge, the discharge cycle is terminated and recharge cycle is initiated. If grid power becomes available during diesel generator operation, the diesel generator is switched OFF and operations continue on grid power.

Battery Recharge with Grid Power: Battery recharge with grid power can start from the beginning (case of grid power becoming available during battery discharge) or can continue over from diesel generator recharge depending on the timing. In both cases, the recharge process will follow the recharge profile shown in Figure 6. If battery becomes fully recharged and grid power is still present, the operations will continue to be powered from grid and no battery discharge will be initiated for the duration of grid availability. In this case battery voltage will revert back to Float voltage.

Battery Discharge after Grid Failure: At the point of grid power failure, the battery capacity is unknown as these events occur in random manner. For the purpose of maximizing the use of grid power and in anticipation of grid power becoming available again, the Hybrid operation will continue with battery discharge cycle. Discharge will continue until:

The preset discharge time elapses (Fixed Daily Time). The preset DOD is reached (Capacity Discharge).

In both cases, the discharge can be terminated earlier as described in “Early Termination of the Discharge Periods”.

Relay 7: Diesel 1 in Operation

Output to DG1 on site. DG is set on for the duration of the signal.

Relay 8: Diesel 2 in Operation

Output to DG2 on site. DG is set on for the duration of the signal.

Fixed Daily

In this mode of operation the total duration of a complete cycle is 24hr. Such duration is necessary as the operation is synchronized with day-night temperature pattern. When an extended recharge cycle is required, the termination of it will still follow the 24hr schedule.

Cycle Duration: A complete cycle consists of discharge and charge periods to the combined total of 24hrs. The discharge period starts at 7pm. It is then followed by recharge period (Diesel Generator ON) for the remaining of the 24hrs. The discharge time is User selectable in the range 1hrs to 22hrs, default setting is 12hrs.

Discharge: The discharge start time and duration are settable. Discharge period starts at 7pm. The discharge time is User selectable in the range 1hrs to 22hrs, default setting is 12hrs.

Recharge: Recharge period (Diesel Generator ON) follows after discharge for the remaining of the 24hrs. Recharge is performed at equalize voltage until added equalize time elapses and at float voltage for the remaining charge time.

High Load Alarm: In order to identify conditions where the load requirements are exceeding the dimensioning of the Hybrid site, an alarm must be generated. The alarm will be triggered upon exceeding the maximum capacity per discharge cycle. The threshold value will be set as default to 40% of battery capacity. It will require capacity measurement per cycle. The alarm will be set once the high load threshold value is reached and is reset at the beginning of the next discharge period. This alarm will also allow distinguishing the root cause of under voltage conditions: is it high load demand or is it a battery ageing and associated loss of capacity issue or insufficient charge capacity.

Capacity Discharge

The cycle period is determined by User selectable capacity discharge of the batteries and associated recharge times. After that the cycle repeats itself. It does not follow a 24hr pattern.

Capacity Discharge and Recharge: The battery discharge period is determined by the percentage of the nominal battery capacity [Ah] that will be discharged per cycle.

The depth of discharge [DOD] per cycle is User selectable in the range 20% to 80%. Default setting is 60%. The value is set as battery capacity at the end of each discharge period. Therefore, if a 60% discharge is chosen, the discharge value is set to 40%.

The time to recharge to full battery capacity depends on battery capacity at the start of the charge cycle and available recharge current.

When the additional charge time has been reached; the generator will be stopped, the recharge cycle will end, and discharge cycle will be initiated.

For practical purposes, the battery capacity at the end of every recharge period is set to 100% as long as Step1, Step 2, and Step 3 have elapsed.

If end of charge is not reached within the set maximum hrs, the recharge will be terminated anyway and discharge cycle will be initiated.

1.3.12 Maximum Current Limit Function

The current available from the rectifiers can be programmed (in AMPS) from 10% to 121% of combined rectifier capacity. The factory setting is 121% unless otherwise specified. The current available from the converters can be programmed (in AMPS) from 50% to 116% of combined converter capacity. The factory setting is 116% unless otherwise specified. Refer to the ACU+ Configuration Drawing (C-drawing) supplied with your system documentation for your system’s settings.

If a rectifier or converter is added, the respective current limit point will automatically increase by the percentage each existing rectifier or converter was set to provide prior to the addition.

If a rectifier or converter is removed from the system (and the Rect Comm Fail or Conv Comm Fail alarm is reset), the respective current limit point will remain unchanged unless the capacity of the remaining rectifiers or converters is not sufficient to maintain the present current limit point. If that happens, the current limit point will automatically increase to the maximum (121% of the remaining rectifiers or 116% of the remaining converters).

2.5.42 Using the Relay Test Feature

Note: The relay test can only be performed when no alarms are present.

Automatic Test

When placed in Relay Automatic Test Mode, all relays on the IB2 board deenergize (when set for Fail Safe), then one-by-one each relay energizes for the time period selected and then deenergizes. If the system is equipped with an EIB board, after the IB2 relays are tested, one-by-one each relay on the EIB board deenergizes for the time period selected and then re-energizes. At the end of the test, all relays are returned to their normal state (if no alarms are present).

Local Menu Navigation: Main Menu / Settings / Power System / General / set the Relay Test Time. then Main Menu / Settings / Power System / General / Relay Test / set to Automatic.

Note: The relay test can be exited at any time by setting the Relay Test to Disabled.

WEB Menu Navigation: Device Information / Power System / Settings Tab / set the Relay Test Time. then Device Information / Power System / Settings Tab / Relay Test / set to Automatic.

Note: The relay test can be exited at any time by setting the Relay Test to Disabled.

Individual Test

When placed in Relay Individual Test Mode, relays can be tested individually. This is the same procedure as “2.5.40 Manually Forcing Relays” except you do not place the Controller in Manual Mode.

Local Menu Navigation: Main Menu / Settings / Power System / General / Relay Test / set to Individual. then Main Menu / Manual / Power System / Relay Output [number] (individually you can set the state of the relays on the IB2 Board). Main Menu / Manual / EIB / EIB1 / Relay Output [number] (individually you can set the state of the relays on the EIB Board).

Select the other state for an alarm relay (active / not active). After confirming the change, the alarm relay will momentarily toggle to the chosen state. The alarm

relay then reverts back to being controlled by the ACU+.

When done, set “Relay Test” to “Disabled”. Note that if there is no User interaction for 10 minutes, the

Relay Test will automatically revert to the “disabled” state. WEB Menu Navigation: Device Information / Power System / Settings Tab / Relay Test /

set to Individual. then Device Information / Power System / Control Tab. (individually you can set the state of the relays on the IB2 Board). Device Information / EIB Group / EIB 1 / Control Tab (individually you can set the state of the relays on the EIB Board).

2.5.43 Spec. No. 588820300 Battery Rack System (Lithium Ion Battery Configuration)

When the ACU+ is equipped with the Lithium Ion Battery Configuration for use with Spec. No. 588820300 NetSure™ Battery Rack System, the only required settings for battery functions is the float voltage and ABCL (Active Battery Charge Current Limit) point.

Note: The maximum value that the ABCL point can be adjusted to is 60A, which is below the maximum

current the battery can handle.

The batteries communicate their status and alarms to the ACU+. The ACU+ displays these via the LCD and WEB interfaces.

Batteries are added to the ACU+ inventory as they are detected. If a battery communications cable is removed, a Li-Ion Battery Communication Fail alarm is generated. If the controller resets while a Li-Ion Battery Communication Fail alarm is active, the alarm changes to a Li-Ion Battery Lost alarm. If you clear any of these alarms, that battery is removed from the ACU+ inventory.

2.7 Power Split Feature

In Power Split applications, the output of the power system controlled by the ACU+ can be connected in parallel with an existing power system. Each system is controlled independently via its own Controller. The ACU+ power system is referred to as the "slave" system and the existing power system as the "master" system. The Power Split feature controls the ACU+ power system’s output voltage and rectifiers' current limit so that the "slave" power system shares the load with the "master" system.

Optional Functions: The ACU+ Controller can mimic the equalize and battery test functions of the “master”

system’s Controller. In addition, the ACU+ Controller can mimic the low voltage load disconnect and/or low voltage battery disconnect functions of the “master” system. This is accomplished by supplying digital signals from the “master” system’s Controller to the ACU+. This allows these functions to remain active in the “master” system.

2.7.1 Overview

See “1.3.7 Power Split Feature”.

2.7.2 How Power Split Works

There are four User adjustable parameters for Power Split. They are:

Slave Curr Lmt: Current limit point for power system designated as the slave system in a "Power

Split" configuration.

Delta Volt: The offset voltage that the power system designated as the slave system in a "Power

Split" configuration is set to. It is suggested to leave this value at the default (0.5 volts).

Proportion Coeff: The proportional coefficient that the power system designated as the slave system

in a "Power Split" configuration is set to. It is suggested to leave this value at the default (30%).

Integral Time: The integral time that the power system designated as the slave system in a "Power

Split" configuration is set to. It is suggested to leave this value at the default (60 seconds). The ACU+ Controller uses these parameters to control the load sharing operation between the two power

systems. Depending on the systems’ configurations, their rectifier capacities, their distribution load capacities, and

the Power Split configuration; four operating modes can occur.

Low Load Operation

When the total load current demand is lower than the SLAVE CURRENT LIMIT value, the ACU+ power system voltage will be increased by the programmed DELTA VOLTAGE setting forcing the ACU+ power system to carry the load. Make sure that the output voltage does not exceed the battery float range recommended by the manufacturer. In this operating mode, no current will be delivered by the existing power system.

Normal Load Operation

When the total load current demand reaches the SLAVE CURRENT LIMIT value, the ACU+ power system operates in output current limit and its output voltage will be decreased (up to the DELTA VOLTAGE setting) in order to regulate the current, allowing the existing power system to deliver the remaining current. Both the ACU+ power system and the existing power system are now providing current to the load.

High Load Operation

If current demand increases and the existing power system reaches its current limit setting, float voltage will again begin to decrease. When the voltage falls below the float setting minus the DELTA VOLTAGE setting, the ACU+ system will come out of current limit and now deliver the additional current necessary to satisfy the load. This operation may occur when the batteries are being recharged, such as after a commercial AC failure.

UM1M820BNA User Instructions Issue AH, March 4, 2013 Spec No. 1M820BNA (Model M820B) Spec No. 1M820DNA (Model M820D)

Over Load Operation

If the load current is greater than the combined current capacities of the ACU+ system and the existing power system, both power systems will go into current limit. Both systems and the batteries will feed the load. The output voltage will depend on the conditions of the batteries. This operation occurs if the total capacity of the rectifiers is too low in relation to the need for increased current.

2.7.3 Operating Modes

Figure 5 illustrates the four modes of operation described above. The Normal Load Operation is considered to be the normal mode. In this mode both the ACU+ system

and the existing parallel power system are both delivering load current. This is main purpose of using Power Split, to avoid putting the burden of delivering the entire load onto one of the two power systems.

2.7.4 Requirements and Conditions

The two DC power systems must be connected in parallel as described in “2.7.5. Paralleling the Existing and ACU+ Power Systems”.

Before paralleling the two systems, the following conditions must be met for proper Power Split function.

Note: The control features of the combined system are limited to those of the original power system. Note: The same type of batteries with an equal amount of cells and the same charging voltages must be

used for both systems.

The float voltage, equalize voltage, and battery test voltage of the ACU+ power system must be set to

the same levels as that of the existing power system.

The remote sense, if available and connected, of both the ACU+ power system and existing power

system must be connected to the same point.

If batteries are used, they must be of the same type. All the functions specific to the existing power system and ACU+ power system and which depend on

the voltage or which act on the voltage must be disabled from the existing power system and ACU+

power system. This includes the following…

any equalization function, any temperature compensation function, any charge control function, any battery discharge test function, and any invalid current alarm.

In lieu of this, if battery charging and battery test functions are implemented in the existing power

system, they can remain if signals for starting are connected from the control system of the existing

system to the ACU+ system.

2.7.5 Paralleling the Existing and ACU+ Power Systems

Admonishments

General Safety

Danger: YOU MUST FOLLOW APPROVED SAFETY PROCEDURES.

Performing the following procedures may expose you to hazards. These procedures should be performed by qualified technicians familiar with the hazards associated with this type of equipment. These hazards may include shock, energy, and/or burns. To avoid these hazards:

a) The tasks should be performed in the order indicated. b) Remove watches, rings, and other jewelry. c) Prior to contacting any uninsulated surface or termination, use a voltmeter to

verify that no voltage or the expected voltage is present. d) Wear eye protection, and use recommended tools. e) Use double insulated tools appropriately rated for the work to be performed.

AC Input Voltages

Danger: This system operates from AC voltage capable of producing fatal electrical shock.

DC Input/Output Voltages

Danger: Connecting the ACU+ power system to an existing power system for “Power Split”

mode involves working on live equipment carrying live loads. This system produces DC power and may require battery to be connected to it. Although the DC voltage is not hazardously high, the rectifiers and/or battery can deliver large amounts of current. Exercise extreme caution not to inadvertently contact or have any tool inadvertently contact a battery terminal or exposed wire connected to a battery terminal. NEVER allow a metal object, such as a tool, to contact more than one termination at a time, or to simultaneously contact a termination and a grounded object. Even a momentary short circuit can cause explosion and injury. Remove watches, rings, or other jewelry before connecting leads. Cover any live busbars with a canvas sheet to prevent short circuits caused by falling tools or parts.

Preparing the Existing and ACU+ Power Systems

Install and turn-up the ACU+ power system as describe in the installation instructions furnished with

the power system.

Set the float voltage on both the existing and ACU+ power systems to the same level. Temperature

compensation functionality, if used, should be disabled on both power systems.

Paralleling the Systems

Connect the Battery and Battery Return busbars of the ACU+ Power System to the main charge

busbars (rectifier side of the shunt) on the parallel power system. Size the cable for the largest current between systems.

Note 1: The connections between the two power systems should be done with power cables

appropriately sized to be capable of carrying the maximum current that can circulate between the two power systems.

UM1M820BNA User Instructions Issue AH, March 4, 2013 Spec No. 1M820BNA (Model M820B) Spec No. 1M820DNA (Model M820D)

Note 2: If the parallel power system incorporates a main plant shunt, the connections of the cables

from the ACU+ power system to the parallel power system shall be made on the main charge busbars (rectifier side of the shunt).

Note 3: To compensate for voltage drop, it is recommended to connect the ACU+ power system’s

remote sense leads (if available) to the same point of sensing as the parallel power system.

Note 4: There shall be only one battery return reference (BRR) cable for the two power systems. If

the cable is appropriately sized on the parallel power system, keep it as the BRR for both power systems. If the cable is not appropriately sized on the parallel power system, install a new BRR cable and connect it preferably to the ACU+ power system since the parallel power system may eventually be phased out.

Note 5: If battery disconnect units (BDUs) are used on the new or parallel power system, these shall

be wired in such a way as to be all triggered simultaneously in order to prevent any overloading of these.

Note 6: For the size and number of bridge cables between the two power systems, take into

consideration the voltage drop, the available connecting points in each system, as well as the fact that these cables are unfused and shall therefore be run on a dedicated cable rack. “C” or “H” taps may be used to make full use of available connecting points.

Note 7: The legacy system retains the function of its controller and the percent of load on each plant

is controlled by the ACU+. Alarms may be sent individually from each plant, or combined using an ACU+ Interface Board and the programmable relays resident in the controller.

Note 8: Add a label on both power systems to indicate that these are operating in the Power Split

Mode with each other.

Optional Function Connections: The following signals from the existing system must be connected

to digital inputs of the ACU+ system interface board for these functions to be active: Equalize Charge in Progress, Battery Test in Progress, Load LVD Active, and Battery LVD Active. Otherwise disable these functions.

2.7.6 Programming the ACU+ Power Split Feature

After an ACU+ power system has been connected to an existing power system and both systems set for the same float voltage, you will have to configure the Power Split parameters in the ACU+.

Procedure

1) Set the Power Split mode to slave. Navigate to Main Menu / Settings / Power System / General / Contactor Mode. Set this parameter to “Slave Control”.

2) Reboot the ACU+ by pressing ESC and ENT at the same time.

3) Navigate to Main Menu / Settings / Power System / Power Split.

4) Navigate to and set the “Slave Current Limit” to a value that will force the ACU+ system’s rectifiers to operate in current limiting mode.

Note: The Slave Current Limit must be set lower than the total distribution current from the two

plants. The default value is 60% of the ACU+ power system’s rectifier capacity.

5) Navigate to and set the “Delta Voltage”. This voltage is by default set to 0.5V but can be readjusted.

If the distribution current is lower than 50% of the total capacity of the ACU+ power system, the

“Delta Voltage” can be adjusted to a lower level than 0.5V to get a system voltage that is closer to the desired float charging voltage.

If the voltage drop between the existing system and the ACU+ system is expected to be >0.5V,

the “Delta Voltage” can be adjusted to a higher level than 0.5 V to get a correct split function.

Temperature controlled battery charging cannot be set in the ACU+ power system in power

split mode. If this function is implemented in the existing power system, a limited function within a temperature range of approximately ±15°C will be achieved if the Delta Voltage is set to a higher level, maximum 2.00V.

If the “Delta Voltage” 0.5V is considered to be too high, the split function can be tested at

various modes of operation to find a lower setting.

Optional Function Setup

Equalize Charge Setup

If the equalize charge function is to be used, equalize charge must be implemented in the existing power system and an equalizing signal from its control unit must be connected to the ACU+.

1) Navigate to Main Menu / Settings / Battery / Charge / EQ Voltage. Set the “EQ Voltage” to the

same value as the equalize voltage of the existing power system.

2) Using the Web Interface (Maintenance / Edit PowerSplit), select the ACU+ digital input

connected to the existing systems equalize control circuit.

Note: Equalize charging is controlled by the existing power system via an incoming digital signal.

The system will remain at the set equalize charge voltage level as long as this signal is active.

Battery Test Setup

If the battery test function is to be used, battery test must be implemented in the existing power system and a test signal from its control unit must be connected to the ACU+.

1) Navigate to Main Menu / Settings / Battery / Test.

2) Navigate to and set the “Test End Volt” to the same value as the end voltage of the existing

power system.

UM1M820BNA User Instructions Issue AH, March 4, 2013 Spec No. 1M820BNA (Model M820B) Spec No. 1M820DNA (Model M820D)

3) Navigate to and set the “Test Volt Lmt” to the same value as the test voltage of the existing

power system.

4) Using the Web Interface (Maintenance / Edit PowerSplit), select the ACU+ digital input

connected to the existing systems battery test control circuit.

Note: Other settings in this menu regarding “Battery Test” are inactive. Note: Battery test is controlled by the existing power system via an incoming digital signal. The

system will remain at battery test as long as this signal is active.

Low Voltage Disconnect Setup

If low voltage disconnect functions are to be used, they must be implemented in the existing power system and signals from its control unit must be connected to the ACU+.

1) Using the Web Interface (Maintenance / Edit PowerSplit), select the ACU+ digital inputs

connected to the low voltage disconnect control circuits.

Temperature Compensated Battery Charge

There is no possibility to activate the “Temperature Compensated Battery Charge” function when the ACU+ power system is configured for “Power Split” mode.

However, the possibility to change the “Delta Voltage” enables the ACU+ power system to follow

the existing power system that has the functionality to a certain limit.

Example: The “Delta Voltage” in the ACU+ power system is set to 1.0V. The existing power system

is set to compensate 3.0 mV/cell/°C. This means that the ACU+ power system can follow the temperature compensation of the existing ;power system in the range of ±14°C from the set normal battery temperature (3.0 mV x 24 cells x 14°C = 1.008 V).

2.7.7 Verifying the Operation of the Power Split Feature

After programming the “Power Split” feature, verify its operation as follows.

a) In a Power Split application where the ACU+ power system is taking all of the load and the rectifiers

in the existing power system are all in the standby mode, use an external dry load bank of sufficient capacity to increase the load on the ACU+ power system over the “SLAVE CURRENT LIMIT” value.

1) Verify that the ACU+ power system limits the total output of its rectifiers to the current

equivalent to this programmed percentage.

2) Verify that the ACU+ power system lowers its output voltage by the value of the programmed

“DELTA VOLTAGE”.

3) Verify that the rectifiers in the existing power system take the additional load as the load

increases pass the “SLAVE CURRENT LIMIT” value.

4) Further increase the load in order to exceed the total capacity of the rectifiers in the existing

power system (or shut down some of the rectifiers in the existing power system if the capacity of the external dry load bank is not sufficient). Verify that the ACU+ power system starts taking the additional load as soon as the total capacity of the rectifiers in the existing power system is exceeded.

b) In a Power Split application where the ACU+ power system is taking only part of the load (operating

continuously at the current level equivalent to the programmed “SLAVE CURRENT LIMIT” percentage) and the rectifiers in the existing power system are taking the rest of the load, use an external dry load bank of sufficient capacity to increase the load in order to exceed the total capacity of the rectifiers in the existing power system (or shut down some of the rectifiers in the existing power system if the capacity of the external dry load bank is not sufficient).

1) Verify that the ACU+ power system starts taking the additional load as soon as the total

capacity of the rectifiers in the existing power system is exceeded.
