Page 9

Electrical Safety

WARNING Hazardous voltages are present at the input of a power system. The DC output from rectifiers and batteries, though not dangerous in voltage, has a high short-circuit current capacity that may cause severe burns and electrical arcing.

Before working with any live battery or power system, follow these precautions:

• Remove all metallic jewelry; e.g., watches, rings, metal rimmed glasses, necklaces.

• Wear safety glasses with side shields (and prescription lenses if necessary) at all times during installation.

• Use OSHA approved insulated hand tools.

Lethal voltages are present within a power system. Never assume that an electrical connection or conductor is not energized. Check the circuit with a voltmeter with respect to the grounded portion of the enclosure (both AC and DC) prior to any installation or removal procedure.

Do not work alone under hazardous conditions.

A licensed electrician is required to install permanently wired equipment. Input voltages can range up to 240Vac. Ensure that utility power is disabled before beginning installation or removal.

Ensure no liquids or wet clothes contact internal components. Hazardous electrically live parts inside this unit are energized from batteries eve n when the AC input power is

disconnected.

Battery Safety

Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel knowledgeable of batteries and the required safety precautions.

Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove all metallic objects from hands and neck.

Use OSHA approved insulated hand tools. Do not rest tools on top of batteries. Batteries contain or emit chemicals known to the State of California to cause cancer and birth defects or other

reproductive harm. Battery post terminals and related accessories contain lead and lead compounds; wash hands after handling (California Proposition 65).

WARNING Follow battery manufacturer’s safety recommendations when working around battery systems.

WARNING Do not smoke or present an open flame when batteries (especially vented batteries) are on charge. Batteries vent hydrogen gas when on charge, which creates an explosion hazard.

Batteries are hazardous to the environment and should be disposed of safely at a recycling facility. Consult the battery manufacturer for recommended local authorized recyclers.

1 Introduction

1.1 Scope of the Manual

This instruction manual covers the features and installation of Argus Technologies’ CXPS 48-1T 48V 375A Power System.

For advanced detail on the system components used in the CXPS 48-1T, please refer to the following manuals:

• Cordex 48-3.6kW Rectifier Module: 010-600-B2

[This manual also provides CXCM4 (controller) installation details.]

(010-567-20 pre-RoHS)

• Cordex Controller (CXC) Software: 034-109-B2 or latest revision of software.

NOTE: To aid the user with installation, frequent reference is made to drawings located at the rear of this manual.

1.2 Product Overview

The CXPS 48-1T is a complete integrated 48Vdc power system with 375A initial capacity; expandable up to 600A. The system utilizes the advanced Cordex controller and 48V 3.6kW rectifier modules. The one-tier (Vista II series) distribution center provides front access for DC distribution, site controller, and battery connections.

Cordex rectifier modules use a high frequency, switched mode conversion technique to provide a fully regulated and isolated DC output from the AC mains. The rectifier input is wide range to allow use on 208/220/230/240/277Vac 50/60Hz electrical service.

Rectifier power modules are “hot swappable” meaning they can be inserted or removed fro m the shelf without cutting power to or from the system or the load.

NOTE: Rectifier modules are not included with the base system, but may be purchased along with the system at the time

of ordering or added after the shelf has been installed.

The shelf rectifier system is designed to operate with the Argus Cordex System Controller (CXC).

This system uses the CXCM4 modular version of the controller, which plugs directly into the Cordex rectifier system shelf. The rectifier/shelf manual provides CXCM4 installation details.

The CXC allows the user to configure, monitor and control the entire DC power system from its touch screen display similar to that used in a personal digital assistant (PDA). Other features of the unit include temperature compensation, auto equalization, remote access, e-mail alarm notification, battery diagnostics, as well as web server and SNMP support for configuration and monitoring.

Details of controller operation are provided in the current version software manual.

2.3.5 Alarm and Control Output Relays

The CXCM4 contains eight Form C digital alarm output relays to extend alarms and control ex ternal apparatus. Each internally generated alarm or control signal may be mapped to any one of the relays, or, several signals may be mapped to just one relay or none at all.

2.3.5.1 LVD Control (External Option)

The LVD Control functions can be hardwired directly from the assigned relay output to an optional LVD override control and distribution alarm card. This provides a safety measure to protect against load disconnect during CXCM4 reset or replacement; e.g. when the controller is off-line. Operators may also perform test and maintenance procedures on the CXCM4 without disturbing the load.

2.3.6 System Fail Alarm/Relay

The CXCM4 system fail alarm (K0) activates because of a major internal failure. Durin g such a condition, the unit will attempt to reset, but if this fails, an alarm condition will be extended to a relay and the red LED on the front panel will illuminate. This is a fail-safe signal to the remote monitoring equipment; i.e. alarm will be extended even if power to the unit is interrupted.

2.3.7 Network Connection and Remote Communications

The Cordex system can be set up, monitored and tested via ETHERNET 10/100 Base-T serial data connec tion. The communication protocol supports a web interface. All alarming and control of Cordex rectifiers is accomplished with a CXC via a CAN bus.

A step-by-step connection wizard – provided to establish remote communications with your CXC – is available via the Argus website (www.argusdcpower.com).

2.4 Cordex 48-3.6kW Rectifiers

2.4.1 Rectifier Overview

The CXPS 48-1T system is provisioned for use with the high-density Cordex 48-3.6kW rectifier system. The system ships complete with one (1) 23” 6-module rectifier shelf installed. Individual 3.6kW (75A) rectifiers are ordered separately.

NOTE: The one (1) installed 6-module shelf with one CXCM4 (controller) allow for up to five (5) 3.6kW modules in a

single 375A system. Distribution and buswork capacity allows for a total system load ca pacity of up to 600A with the installation of an additional rectifier shelf.

2.4.2 Remote Control

All alarming and control of Cordex rectifiers is accomplished with a CXC via a CAN bus. The Cordex rectifier shelves provide connections for serial communications with other rectifier shelves as well as supervisory and control panels.

2.4.3 Rectifier Front Panel

LEDs

Thumbscrew

Figure 4–Cordex 48-3.6kW modular switched mode rectifier

2.4.3.1 LEDs

The front panel LEDs provide:

• Rectifier status summary,

• Rectifier software upgrade in progress indication,

• Locate module pattern.

Rectifier status summary will show the rectifier alarm status, communication fail status and rectifier on/off status.

AC ON

The top LED (green) is on when AC is within valid range. The LED will flash (twice per second) when AC is outside the nominal range – AC voltage is invalid if the AC Mains Low or AC Mains High alarm is active. The LED turns off when AC has failed.

Argus Technologies Ltd. 053-392-C0 Rev A WC

Page 18

DC ON

The middle LED (green) is on when the rectifier is delivering power to the load. The LED turns off when the rectifier is off; e.g., when commanded via the CXC.

ALARM

The bottom LED (red) is on continuously in the event of an active Module Fail alarm; if the module is unable to source power as a result of any of the following conditions:

Output fuse blown AC Mains Input Fail Module fail (ramp test fail) High voltage (OVP) shutdown Thermal shutdown Local shutdown UPF fail No output power Fan (1 and 2) fail.

The LED will flash (twice per second) when a minor alarm is detected; if the modules output capability has been reduced or a minor component failure is detected during the following conditions:

VAC meter fail AC foldback Remote equalize Fan (1 or 2) fail Low output voltage High output voltage Current limit (programmable option) Power limit (programmable option) High temperature foldback Temperature sense fail Soft start operation Communications lost.

The LED remains off in the absence of an alarm. If the unit output is not connected to a battery or parallel rectifier, the LED will extinguish if no AC power is present.

LED Activity During Software Upload

When a rectifier software upload is in progress, the LEDs will behave in a distinctly different way to indicate new rectifier software is being transferred from the CXC.

When a rectifier data transfer is in progress, all three LEDs will flash in a sequence lasting 1.5 seconds. When the last LED is lit, the sequence is repeated beginning at the first LED.

LED Activity During ‘Locate Module’ Command from CXC

When the ‘locate module’ command has been received from the CXC, the LEDs will behave in another distinct fashion so that the rectifier is easier to visually identify among adjacent rectifiers.

This state is entered when commanded via the CXC. The LEDs will flash in a ping-pong pattern repeating every 2 seconds.

The ping-pong pattern lights each LED sequentially. After the last LED is lit, each LED is lit in reverse sequence. When the first LED is lit, the pattern repeats. The effect makes it appear as if the light is bouncing between the first and last LED.

2.4.3.2 Mechanical

A thumbscrew is provided to secure the rectifier into the shelf. During normal operation the rectifier shall be locked into position. A handle (or grip) is incorporated into the front panel to facilitate the removal of the rectifier from the shelf. No special tools are required.

2.4.4 Rectifier Rear Panel

Located on the rear panel of the rectifier is a single connector for shelf power and communications.

2.4.5 True Module Fail Alarm

The power modules have a “true” fail alarm. This provides a true indication of the power module’s ability to source current. When the module’s output current drops below 2.5% of the rated output a low output current condition is detected and the Module Fail detection circuit is activated. This circuit momentarily ramps up the output voltage to determine if the module will source current. If no increase in current is detected, the Module Fail alarm is activated. The module will test once every 60 seconds for the condition until current is detected. Output voltage ramping will cease upon detection of current

. A minimum 2.5% load is required to avoid the Ramp Test Fail alarm; this can typically be provided with the parallel system battery. Activation of this alarm could indicate a failed module or a failed load.

Under normal conditions, a battery connected to the output of the rectifier will draw current when the voltage ramp occurs. Therefore the rectifier fail

alarm will not be generated with a battery connected.

Argus Technologies Ltd. 053-392-C0 Rev A WC

Page 19

NOTE: For Cordex rectifier systems without batteries (or with a very light load; below 2.5% of rated output) it is

recommended that the ramp test be disabled to avoid nuisance alarms. The Ra mp Test feature is enabled/disabled via the CXC menu item: Rectifiers, Configure Settings.

2.4.6 Heat Dissipation

Each rectifier module is equipped with at least one front-mounted fan. The fan operates at temperatures above 0°C (32°F). Cooling of the module is front-to-rear with the exhaust air exiting at the back. The fan is variable speed; which is determined by heatsink temperature and load.

2.4.7 Over Temperature Protection

Each rectifier module is protected in the event of an excessive increase in temperature due to component failure or cooling airflow blockage. During over temperature conditions, the rectifier limits the output power as well as the output current. If temperature continues to increase, a shutdown of the rectifier is initiated. The rectifier shall restart automatically if the temperature has returned to a safe level.

2.4.8 Wide AC Range

A minor alarm is generated when the AC input voltage drops below specification. Rectifier output power is reduced linearly between 176Vac and 150Vac to 75% of the rated output power (the unit will deliver derated output power down to 90Vac).

At 90Vac, the module will shut down and will not restart until the AC is greater than or equal to 150Vac; however, the restart voltage depends on the load current. At reduced load current the unit may restart with the input voltage as low as 100Vac.

For voltages above 277Vac, power factor and total harmonic distortion may be derated. Up to 320Vac, the rectifier will be operational and shall not suffer any damage.

2.4.9 AC Inrush/Transient Suppression

The inrush current of the rectifier module is limited to the full load steady state line current to prevent surge on the AC line. Modules are also protected from input lightning and transient surges in accordance with IEEE/ANSI C62.41 Category B3.

2.4.10 Soft Start

To eliminate an instantaneous demand on the AC source, a soft start feature is employed. Soft Start, sometimes referred to as “current walk-in”, works by gradually (up to five seconds) ramping the current limit up from zero to the actual or defined customer setting. The rectifier output voltage is ramped up from the minimum voltage to the float voltage.

2.4.11 Start Delay

The rectifier modules are equipped with a delay timer in order to stagger start a series of modules to prev ent excessive loading of generators upon start up. The built-in timer delays the turn on of the module depending on the value selected (up to 120 seconds) via the CXC. A minimum one-second delay is preset to allow charging of the input capacitors.

2.4.12 Current Limit/Short Circuit Protection

The current limit function determines the maximum output current limit of the rectifier module, regardless of output voltage or power. Maximum output current is limited to a constant value down to short circuit condition. Current limiting can be used to mate the rectifier output current ampacity to the needs of the load and parallel battery to minimize excessive battery recharge current.

The rectifier will sustain a short circuit at the output terminals indefinitely. The maximum short circuit current shall not exceed 105% of the rated full load current.

Argus Technologies Ltd. 053-392-C0 Rev A WC

Page 20

2.4.13 Power Limiting

Each rectifier module is designed to limit power output to the module specification. This enables more current to be supplied at lower output voltages, and allows matching of output to the demand of constant power loads, normally seen with telecom equipment.

This feature may also be used for a faster recharge of flooded batteries paralleled with the load.

NOTE: Current limiting overrides the power-limiting feature.

2.4.14 High Voltage Shutdown (HVSD)

This feature provides protection to the load from over voltage conditions originating from the rectifiers. It operates by shutting down the offending rectifier module when a high output voltage condition occurs. Indication is through the red Alarm (Module Fail) LED. Modules will restart automatically; however, if more than three over voltage conditions occur in one minute, the module will latch off and remain shut down until it is reset (by restarting the rectifier) via the CXC.

2.4.15 Battery Eliminator Operation

Rectifier modules maintain all specifications (except where indicated) with or without a battery attached in parallel to the output; however, if a battery or another module supplying DC voltage in parallel is not present, there will be no monitoring or control activity if there is an AC power failure or input fuse failure.

4.5 Battery Installation

This information is provided as a guideline and is not meant to imply that batteries are part of this power system.

WARNING Follow battery manufacturer’s safety recommendations when working around battery systems and review the safety instructions provided in this manual.

4.5.1 Preparation/Mounting

Batteries should be located in a temperature-controlled environment. The temperature should be regulated at approx. 25°C (77°F). Significantly lower temperatures reduce performance and higher temperatures decrease life expectancy.

Provide adequate ventilation. VRLA batteries, though not requiring the special ventilation requirements of a flooded battery, should not be installed in an airtight enclosure. Hydrogen gas may be vented in a fault condition; i.e., failed battery.

Before assembly, clean cells (where applicable) as per the battery manufacturer's recommendations. First neutralize any acid with a baking soda and water solution. Then wipe the cells with clean water.

4.5.2 Installation of Batteries Verify that all battery breakers, DC circuit breakers, and fuses on the distribution panels are either

in the OFF position or removed.

Use a corrosion-inhibiting agent, such as NO-OX-ID “A”™, on all battery terminal connections.

1. Assemble battery rack (if required) and the cells or mono-blocks as per the installation instructions supplied with the batteries.

2. Ensure that the battery output cabling will reach the [+] and [–] terminals of the series battery string and that the batteries are oriented correctly for easy installation of the inter-unit “series” connectors.

3. Remove any NO-OX-ID “A”™ grease from battery terminals.

4. Burnish terminal posts with a non-metallic brush, polishing pad or 3M Scotch Brite™ scouring pad.

5. Apply a light coating of NO-OX-ID “A”™ grease to the terminal posts.

6. If lead plated inter-unit connectors are used, they should also be burnished and NOOX-ID “A”™ grease applied as above. Install the inter-unit connectors.

7. After all battery connections are completed, torque per battery specifications (typically 100 in-lbs).

NOTE: See system startup procedure before connecting batteries online.

5 Wiring

This chapter provides cabling details and notes on cable sizing for DC a pplications with respect to the product.

WARNING Ensure that power is removed by turning off rectifiers and removing battery line fuse or connection before attempting work on the wiring connections. Use a voltmeter to verify the absence of voltage. Clearly mark the correct polarity of the battery leads before commencing work on DC connections.

Refer to the previous (Installation) chapter for safety precautions and tools required.

5.1 Grounding

The isolated power system battery return bus (BRB) should be connected to the building master ground bus (MGB) or floor ground bus (FGB) in a larger building. This acts as a system reference and as a low imp edance path to ground for surges, transients, noise, etc. The MGB or FGB should have a direct low impedance path to the building grounding system. The cable from the power system to the MGB or FGB should be sized to provide sufficient ampacity to clear the largest fuse or breaker on the power system, excluding the battery protection fuse or circuit breaker. This is the minimum requirement; other factors including length of cable and special grounding requirements of the load should also be factored in. The insulated cable should be equipped with two-hole crimp type lugs and should not have any tight bends or kinks.

Power System Ampacity Ground Reference Conductor Size

< 30A #10 30 – 100A #6-2 100 – 400A 0000 400 – 800A 350 MCM > 800A 750 MCM

Table B–Typical ground reference conductor selection

The power system frame must also be connected to the MGB or FGB. This is done for personnel safety and to meet many Telco grounding requirements. Each bay should have its own frame or site ground connection (see Figure 6). Refer also to the Customer Connections drawing at the rear of the manual.

5.2 AC Feeder Protection/Sizing

To maximize system reliability, each power module should be fed from a dedicated protection feeder breaker located at the AC distribution panel. The feeder breaker can also act as the disconnect device for the connected module. Refer to the specifications at the front of this manual for Argus recommendations.

5.3 AC Input Connections

CAUTION: AC input wires should be routed in flexible or rigid conduit as far away as possible from the DC power wires to minimize EMI disturbances.

Ensure all modules are removed from the shelf and refer to the Customer Connections drawing at the rear of the manual for AC terminal block location.

Remove the covers (2 places) from the rear of the shelf to expose the AC input terminal blocks, L1 and L2 for each rectifier. Each terminal pair relates to an individual power module as marked.

WARNING Use care when removing or replacing the covers for the AC input connections. Never assume that an electrical connection or conductor is not energized.

The wireway is designed for two customer-supplied 1” conduit fittings for AC supply located one on each side of the shelf. Attach the conduit retainers to the wireway hole(s) and route the AC cables through. Secure the wire s to the AC input and chassis ground terminals as required. Tighten the cable con nector to the AC cable (conduit similar).

Replace rear cover(s) once all connections have been completed.

Argus Technologies Ltd. 053-392-C0 Rev A WC

Page 27

5.4 DC Output Connections

WARNING Leave cables or bus bars disconnected at battery and verify output polarity using a voltmeter. Make battery connections only after all other wiring is completed.

DC output wire shall be UL approved XHHW or RHH/RHW (for Canadian users, RW90 Type). Control and sense wires shall be UL approved Style 1015 (for Canadian users, TEW type).

The common output leg of the rectifier system should be connected to ground. This is typically done at the load common termination point.

5.4.1 Battery Connections

Battery cables should be sized for a 0.25 V drop from battery to the power system at full load including anticipated growth. The cables should also meet ampacity requirements. Cables terminating directly on battery posts or connection details should be secured so that there is no stress on the battery posts. Lead plated lugs and lead plated or stainless steel hardware should be used on all terminations at vented batteries to reduce corrosion.

Prepare, route and connect cables from power system to battery termination details. Terminating points should be burnished and a corrosion-inhibiting agent, such as NO-OX-ID “A”™, should be applied to all battery terminal connections.

The 600A One Tier Distribution Center (Vista II One-Tier UDC) allows for (4) sets of battery connections for both hot and return. Connections allow for 3/8” on 1”C lug connections.

Return

Site Ground

Figure 6–Vista II one-tier battery connections (hot and return)

NOTE: Final connection to battery live should not be made, insulate and leave disconnected or remove the battery fuses.

Switch battery contactors off (if used). See system startup procedure before connecting batteries online.

5.4.1.1 Back-To-Back Connections

To allow for back-to-back connections on the battery bus bars, the PEM nuts must be removed from rear side of each bar. This requires rear access to the system. Reference Figure 7 for PEM nut removal detail.

Page 28

To remove PEM nuts:

1. Place a 9/16" socket over the PEM nut to be removed.

2. Insert a 3/8" bolt through the socket and thread into the PEM nut.

3. Using a socket wrench with a 9/16" drive, tighten the head of the bolt until the action pulls the PEM nut from the bus bar.

Figure 7–PEM nut removal for back-to-back connections on the battery bus bars

5.4.2 Load Distribution

Bolt through socket

PEM removed

Refer to guidelines supplied with the load equipment. Typically distribution cables are sized to provide a 0.5 V loop drop at full load as well as meeting ampacity requirements of the protection fuse or circuit breaker.

5.4.2.1 AM Breakers

The CXPS 48-1T is factory configured with (18) total single-pole AM-type plug-in breaker positions for 48V load distribution. The breakers have bullet terminals, which plug into the breaker tier for simple installation and removal. Each distribution tier has a 1/4” – 5/8”C hole set for the breaker output and on the ground bar located directly above the breaker panel.

• 1 to 100 amp breakers require 1 position.

• 110 to 150 amp breakers require 2 positions*.

• 175 and 200 amp breakers require 3 positions*.

* 2-position and 3-position breakers have an output adapter that provides a single 3/8" hole on a 1" center output. The return must use one of the battery or rectifier terminations.

Figure 8–Front view of the 2-Pole and 3-Pole output adapters

It is recommended to install the largest capacity circuit breakers on the top distribution tier to optimize cable management. It is imperative to plan circuit breaker installation to allow for

Argus Technologies Ltd. 053-392-C0 Rev A WC

5.6.2 Digital Inputs

The digital input channels are used to monitor various alarm and control signals. All input cha nnels are voltage activated and accept a bipolar (i.e. negative or positive) DC signal directly.

5.6.2.1 Connection Method

Typical Argus systems use the “reset with Hot and trigger with Ground” connectio n. The digital input is wired in such a way that the Hot is wired directly into one of the input terminals; e.g., negative input for -48V systems. The other input terminal is wired to the Ground (common) of the system through a relay (dry contact – usually located on the equipment requiring monitoring). This method (see Figure 14) allows the digital input to receive (or not receive) a Ground signal on an alarm.

Figure 14–Showing digital input connection method

5.6.2.2 Programming the Digital Input

The digital input channels can be programmed for “active high” or “active low.” Active high indicates “alarm on the presence of a ground signal” and active low indicates “alarm on the removal of a ground signal.” See CXC Software manual for detailed instruction on programming.

5.6.3 Relay Outputs

Terminals provide contacts for extending various alarm or control signals. Each relay output can be wired for NO or NC operation during an alarm or control condition. See Figure 15.

Relays can be programmed to energize or de-energize during an alarm condition (see CXC Software manual). When the CXC reset button is pressed or power is lost, all relays de-energize.

5.6.3.1 System Fail Relay

System Fail output relay (K0) is fail-safe and will de-energize during an alarm condition.

5.6.3.2 LVD Control

The LVD Control functions can be hardwired directly from the assigned relay output to the LVD contactor panel. See Controls Menu Defaults in the CXC Software manual.

Figure 15–Showing relay connections in the de-energized state

5.6.4 CAN Port

The CAN port or “CAN bus” allows communications between the CXC and Co rdex series rectifiers or other CXC system peripherals. These are located on the left side of the rectifier shelf (as viewed from the front).

5.7 Network Connection and Remote Communications via CXC

The Cordex system can be set up, monitored and tested via ETHERNET 10/100 Base-T serial data conne ction. The communication protocol supports a web interface.

Some standard scenarios are described below:

5.7.1 Ethernet Port for Network Connection (Standard Network Cable)

The Ethernet port is designed for CXC connection to a user supplied network (TCP/IP secured by user) via a front panel RJ-45 jack. Connect to the Cordex shelf using a standard network cabl e.

5.7.2 Ethernet Port for Local Connection (Crossover Cable)

Local access (e.g. laptop computer) is also possible from the Ethernet port connection using a standard network crossover cable.

6 System Startup

Visually inspect the installation thoroughly. After completing the system installation and power system wiring, perform the followi ng startup and test

procedure to ensure proper operation:

6.1 Check System Connections

• Ensure ac is off, battery is disconnected, and all power modules are removed from the shelf.

• Triple-check the polarity of all connections.

6.2 Verify AC and Power the Rectifier Shelf

• Install one power module.

• Verify ac input voltage is correct and turn on the corresponding feeder breaker.

• The power module OK LED should illuminate after a preset start delay.

• Using the CXC, test functionality of various module alarms and controls.

6.3 Check Battery Polarity and Connect

• Verify correct battery polarity using a voltmeter (ensuring no cells or batteries are reversed).

• Connect battery as required to the output of the system.

• Install remaining power modules.

• In the adjustments menu of the CXC, set float and equalize voltage to the levels specified by the battery

manufacturer.

• Using the CXC, test functionality of various module alarms and controls. In addition, perform a load test with

the system using a resistive load box as needed.

• Enable the temperature compensation (temp comp) feature (Batteries menu) and program the settings for

slope and breakpoints (upper and lower) with respect to the specific batteries used.

6.4 CXC Reset

The reset button located on the front panel of the optional CXC is for restarting the microprocessor. When pressed momentarily, the unit beeps twice then resets. The front-panel LED’s will illuminate temporarily, but will extinguish after the system has finished its 15-second self-test.

WARNING Before removing a CXC from a live system, or performing controller maintenance, an external LVD override is required to avoid a disruption of service.

The LVD Control functions are hardwired directly from the assigned relay output to the LVD override control and distribution alarm card (Figure 13).

Place the LVD Control switch to the OVERRIDE IN position to keep the LVD contactor engaged.

WARNING Do not leave the switch in the OVERRIDE IN position. Doing so may result in a complete discharge of the batteries during a power failure situation.

To allow the CXC to resume automatic control of the LVD contactor, check that the AUTO IN (green) LED is lit confirming that the CXC will keep the LVD contactor engaged. Then you may return the LVD Control switch

to the AUTO IN position.

7 Operation

7.1 Main Rectifier States

Rectifier operation can be broken up into five main states:

1. Off,

2. Start delay,

3. Soft start,

4. Normal operation,

5. Turning off. Each state is characterized as being distinct and necessary for the operation of the rectifier. These states are

briefly described below.

7.1.1 Off State

The rectifier will be in the Off state immediately after power is applied to the rectifier or after a rectifier shutdown. The shutdown source may be remote or local shutdown, AC shutdown, OVP or thermal shutdown.

When the rectifier is in this state the DC-DC converter is turned off and the CXC will be monitoring its inputs for the proper conditions to begin the start up sequence.

When the conditions have been met for the rectifier to start up, it will transition to the Start Delay state.

7.1.2 Start Delay State

When the rectifier is in the Start Delay state, the DC-DC converter is held off and still not sourcing power and is waiting for a given amount of time before transitioning to the next state.

When in this state, the CXC continues to monitor its inputs. After the Start Delay state the rectifier will transition to the Soft Start state.

NOTE: Soft start, or current walk-in, gradually increases the voltage and current output of the rectifier upon startup. This

is done to reduce the instantaneous load on the AC source.

7.1.3 Soft Start State

When the Soft Start state is entered, the rectifier will be turned on and the output voltage and output current will be gradually increased. If a load is present, the rectifier will begin to source power.

When the voltage and current limit ramps have finished, the rectifier will transition to the Normal Operation state.

7.1.4 Normal Operation State

The Normal Operation state is the state that the rectifier will be in performing all of the rectifier functions and features specified herein.

From this state, the only valid transition is to the Turning Off state. This transition will happen if the rectifier is required to shut down.

7.1.5 Turning Off State

The Turning Off state is entered because a short delay is required before the rectifier actually turns off to take care of any initialization requirements.

When this short delay has elapsed, a transition to the Off state is made.

7.2 Main Rectifier Modes

In addition to Main Rectifier States, there is a set of Main Rectifier Modes. These modes can be divided into two categories as follows:

Argus Technologies Ltd. 053-392-C0 Rev A WC

Page 38

7.2.1 Output Voltage Modes

Voltage modes can be thought of as modes that, under software control, can directly adjust the output voltage. The qualification of ‘under software control’ is made because there are processes that occur in the rectifier that can change the output voltage that do not adjust the output voltage directly (such as the rectifier being in cu rrent limit).

The following table lists four Output Voltage Modes and a description of when they are active:

Output Voltage Modes Active when…

Float Output voltage is set to the float voltage setting. Equalize Output voltage is set to the equalize voltage setting. Battery Test Output voltage is set to the battery test voltage setting. Safe Output voltage is set to the safe mode voltage setting.

7.2.2 Output Current/Power Modes

These modes directly affect the output current and power. The following table lists the four Output Current/Power Modes and a description of when they are active:

Output Current/Power Mode Active when…

Temperature foldback mode Output current and power limit have been reduced due to high temperature of the

AC foldback mode Output current and power limit have been reduced due to low AC input voltage. Note:

Short circuit foldback mode Output current limit has been reduced due to a short circuit at the output. Internal fault foldback mode Output current limit has been reduced due to an internal fault.

Table D–Output voltage modes

heatsink or internal ambient temperature sensor.

this will reduce the risk of tripping an AC breaker due to increased AC current draw as the AC voltage decreases.

7.3 Factory Ranges and Defaults

The following table lists the rectifier settings/ranges/defaults; changes are made via the CXC:

Setting Range (minimum to maximum) Default

Float (FL) Voltage 47.5 – 58.2V 54V Equalize (EQ) Voltage 49.8 – 60.2V 55V Battery Test (BT) Voltage 44 – 52V 46V OVP See note below – 63V 57V Current Limit (CL) 23 – 100% 100% Power Limit (PL) 0 – 100% 100% Module Start Delay 0 – 250s 1s System Start Delay 0 – 600s 0s Low Voltage Alarm (LVA) 42 – 52V 44V High Voltage Alarm (HVA) 52 – 63V 55.5V EQ Timeout 1 – 2399h 30h BT Timeout 1 – 250h 8h Softstart Ramp-rate Normal/Fast Normal CL/PL Alarm Enable/Disable Enable Remote Shutdown Enable/Disable Enable Ramp Test Enable/Disable Enable

Table E–Output current/power modes

Table F–Cordex 48-3.6kW factory ranges and defaults

NOTE: OVP cannot be set below the present system/FL/EQ/BT voltage setting or the safe mode voltage of 51.4V.

Return Material Policy

Our return policy is designed to ensure prompt, efﬁcient and high quality factory service. A service request order (SRO) number must be obtained before products can be accepted for servicing by the Argus factory. For returns to an authorized service center (refer to the Service Centers document), please consult the individual service center for speciﬁc return policies and instructions.

To obtain an SRO number for a factory return, customers must call the appropriate location with the product serial and model number, as well as a brief description of the problem, shipment instructions and billing details.

The original packing container should be used whenever possible. The box should be completely enclosed and constructed of wood or double-wall, corrugated cardboard. At least 3” of foam or shock absorbing packing material must surround the unit. Both the shipping documents and the outside of the box must have the SRO # clearly marked and the product shipped prepaid to the Argus factory service center. Argus will endeavor to repair products within ﬁve working days of receipt. Repairs to the returned product are warranted for a period of six months. A service charge may be applied if no fault is found in the returned product. Argus will not accept products without an SRO number.
