Power/Distribution Bay, this panel houses the Meter-Control-Alarm (MCA) assembly.

This panel in the Primary Power/Distribution Bay also houses the optional LMS Main

CPU circuit card of the integrated LMS Monitoring System. In a Secondary

Power/Distribution Bay, this panel can be equipped with an optional LMS Expansion

CPU circuit card. (The optional LMS Monitoring System provides a higher level of monitoring and controlling capabilities to the power system.)

The Monitor and Control Panel in both Primary and Secondary Power/Distribution

Bays contain a seven-slot card cage to house MCA alarm relay circuit cards, MCA input/output (I/O) circuit cards, and optional LMS I/O circuit cards. (If a Secondary

Power/Distribution Bay is to be equipped with optional LMS I/O circuit cards, it must also be equipped with an LMS Expansion CPU circuit card.)

Power Only Bays

The system can consist of one (1) Primary Power Only Bay and up to nine (9)

Secondary Power Only Bays.

Each Power Only Bay can be equipped with up to ten (10) Rectifiers.

Each Power Only Bay contains a Monitor and Control Panel. In the Primary Power

Only Bay, this panel houses the Meter-Control-Alarm (MCA) assembly. This panel in the Primary Power Only Bay also houses the optional LMS Main CPU circuit card of the integrated LMS Monitoring System. In a Secondary Power Only Bay, this panel can be equipped with an optional LMS Expansion CPU circuit card. (The optional

LMS Monitoring System provides a higher level of monitoring and controlling capabilities to the power system.)

The Monitor and Control Panel in both Primary and Secondary Power Only Bays contain a seven-slot card cage to house MCA alarm relay circuit cards, MCA input/output (I/O) circuit cards, and optional LMS I/O circuit cards. (If a Secondary

Power Only Bay is to be equipped with optional LMS I/O circuit cards, it must also be equipped with an LMS Expansion CPU circuit card.)

Each distribution bus accepts a choice of 218-type circuit breakers and TPL-type fuses.

B )

A Distribution Only Bay may also be equipped with an optional distribution panel which accepts a choice of TPS/TLS-type fuseholders or Bullet Nose-type circuit breakers.

Rectifiers

The rectifiers provide load power, battery float current, and battery recharge current during normal operating conditions.

MCA (Meter-Control-Alarm)

The MCA controls the operation of the rectifiers and provides power system control, metering, monitoring, and alarm functions.

MCA Local Control Panel: This panel is located on the front of the Primary

Power/Distribution Bay or Power Only Bay and contains a keypad, display, and indicators for local MCA User interface.

MCA Relay Circuit Card: Each MCA relay circuit card provides six (6) sets of

Form-C relay contacts for customer external alarms. These relays are User programmable for various power system alarms. Up to sixteen (16) MCA relay circuit cards can be installed in the Primary and Secondary Power/Distribution and Power

Only Bays. The Primary Power/Distribution and Power Only Bays are factory equipped with two (2) MCA relay circuit cards.

MCA I/O Circuit Cards: The MCA I/O circuit cards provide analog inputs/outputs and binary inputs. Up to sixteen (16) MCA I/O circuit cards can be installed in the

Primary and Secondary Power/Distribution and Power Only Bays.

Optional Integrated LMS Monitoring System

The LMS Monitoring System consists of an LMS Main CPU circuit card, optional LMS

Expansion CPU circuit cards, optional LMS I/O circuit cards, optional LMS Expansion

Cabinet, and optional LMS Expansion Assemblies.

The LMS Main CPU circuit card is mounted in the Primary Power/Distribution and

Power Only Bays. Each Secondary Power/Distribution and Power Only Bay that is to be equipped with optional LMS I/O circuit cards must contain an LMS Expansion

CPU circuit card. LMS Expansion Cabinets and LMS Expansion Assemblies are available that mount into customer equipment.

The LMS Monitoring System is factory integrated within each Power/Distribution,

Power Only, and Distribution Only Bay and requires no additional customer interconnections within the bays. Simple cable connections between the

Power/Distribution, Power Only, and Distribution Only Bays complete the interbay connections required. Separate analog, binary, and relay circuit cards do not have to be supplied for power system monitoring. Analog, binary, relay, and temperature circuit cards can be provided to monitor equipment external to the power system.

The LMS input circuit cards monitor a variety of analog, binary, and temperature points external to the system. An LMS relay output circuit card is also available which provides programmable relays. These relays may be used for external alarms, or to control other equipment.

The LMS Monitoring System can be accessed via a local port, a modem port (when optional modem is ordered), an optional TL1 port, and an Ethernet port (for Telnet access, optional Web access, optional SNMP access, optional TL1 access, and

Email alarm reporting).

The LMS Monitoring System collects data from the power system and the input circuit cards monitoring external points. The data collected is used for alarm processing and reporting, and to provide statistics.




User Instructions


Section 5877


The LMS Monitoring System is capable of reporting alarm conditions to a remote terminal, pager, Email address, via SNMP traps over Ethernet when the SNMP option is ordered, or via TL1 (over Ethernet) when the 'TL1 over Ethernet' option is ordered. TL1 is also available via a serial connection in 'direct mode'. For remote terminal or pager notification, the LMS Main CPU circuit card must be equipped with the optional modem. Two types of alarm reporting mechanisms are provided,

Section 5877


Method 3 (Automatic Test/Equalize) Procedure

User Instructions


In this method, a user enables the Automatic Equalize feature via the MCA Control

Panel. The system is automatically placed in the equalize mode and automatically returns to float mode for the conditions as described above. Follow the procedures described below.

Note: The automatic equalize feature is intended for use only with wet cell batteries.

Using this feature with valve regulated batteries is not recommended.

Description

This feature can be enabled or disabled by a user via the MCA. The default state is disabled.

The Automatic Equalize feature is a time based function which is controlled by a customer selectable multiplier and by the "System Battery is on Discharge" alarm setpoint. The MCA’s default setting is for a multiplier of zero, which disables the

Automatic Equalize feature.

When the Automatic Equalize feature is enabled, if system voltage drops to less than the

"System Battery is on Discharge" alarm setpoint, the MCA initiates a timing cycle to measure the discharge time period. The MCA requires at least 15 minutes of continuous

"System Battery is on Discharge" alarm in order to prevent nuisance equalization cycles.

When system voltage rises to above the "System Battery is on Discharge" alarm setpoint, the MCA ends the discharge timing cycle and (assuming a minimum of 15 minutes has elapsed) places the Rectifiers into the equalize mode for a customer selectable multiple of the discharge time period (the discharge time period includes the initial 15 minutes).

The equalize time period can be set for 0 to 15 times the discharge time period, up to a maximum of 300 hours. A zero (0) setting disables the feature.

When the Automatic Equalize feature is enabled, the MCA prevents a user from setting the equalize value lower than the float setpoint. If the equalize value is set first, the MCA automatically sets the Automatic Equalize Multiplier to zero (0), disabling the feature.

Manually setting the system to float or equalize mode cancels the automatic function, if active.

Note: Equalization is only effective if the correct multiplier is entered to allow the battery to charge to capacity. It makes no sense to end the equalize cycle before battery capacity has been restored. To determine the multiplier, load current and system capacity must be known. For example, consider a system with 200 amps of

Rectifier capacity and 150 amps of load. If there is a 2-hour outage of AC power,

300 amp-hours (150 x 2) will be drained from the battery. When AC power is restored, the battery charge current will be 50 amps (200-150), and it will take at least 6 hours (300/50) to replace the battery capacity. In this scenario, the multiplier must be set greater than 3 for the Automatic Equalize feature to have any effect.

Enabling and Disabling the Automatic Equalize Feature: To enable, set the "AUTO

EQUALIZE FOR ## x DISCHARGE" menu item in the MCA Configure Menu to a value between 0 and 15. To disable, set the "AUTO EQUALIZE FOR ## x DISCHARGE" menu item in the MCA Configure Menu to 0. A step-by-step procedure is provided next.



SELECT DOWN arrow key until "GO TO FUNCTION MENU" is displayed. Press

Note: If "AUTO EQUALIZE FOR ## x DISCHARGE" is displayed, the system is already set for Automatic Equalize. In this case, you can proceed with steps

4) through 7) to change the current setting, or proceed with step 8) if no changes are required.

Note: If "END AUTO EQUALIZE IN hhh.hh HOURS" is displayed, the system is already set for Automatic Equalize, and an Automatic Equalize is in progress.

In this case, you can proceed with steps 4) through 7) to cancel the Automatic

Equalize in progress and change the current setting, or proceed with step 8) to proceed with the Automatic Equalize in progress and make no changes.


5) Press the FUNCTION SET YES (+) or FUNCTION SET NO (-) key until the desired value is displayed, then release the key. Note that as you scroll below 1,

"AUTO EQUALIZE IS DISABLED" is displayed. Scroll back up to redisplay

"AUTO EQUALIZE FOR ##".

Note: Navigating to "END AUTO EQUALIZE IN hhh.hh HOURS" of the MCA Configure

Menu displays the hours remaining in an automatic equalize period, if active.

Note: Auto Equalize is canceled and the system is placed in the float mode if any of the following occurs.

1) Manually placing the system in the float mode by navigating to and activating

"TEST/EQUALIZE MODE ACTIVE. SET FLOAT?" menu item in the MCA

Function Menu.

2) Resetting the "AUTO EQUALIZE FOR ## x DISCHARGE" value in the MCA

Configure Menu when "END AUTO hhh.hh HR" is being displayed, as described in the previous procedure

3) Applying an external test/equalize signal.




Section 5877


Method 4 (External Test/Equalize) Procedure

User Instructions


In this method, a user (or external equipment) places the system in the test/equalize mode by applying an external signal to the system. The system returns to the float mode when the external signal is removed. This method overrides the other three methods.

Placing the System into Test/Equalize Mode: Apply an external test/equalize loop closure to the system's remote equalize terminals.

Returning to Float Mode: Remove the external test/equalize loop closure from the system's remote equalize terminals.

Note: If a manual test/equalize, manually initiated timed test/equalize ,or automatic equalize is in process; it is canceled and the system returns to float mode when system ground is removed from the test/equalize terminal.

MCA “POWER SHARE” FEATURE

Section 5877


Description

The MCA Power Share feature allows you to connect a Spec. No. 582140000 Power

S ystem (referred to as “New Power System” in this document) to an existing DC power system (referred to as “Existing Power System” in this document) instead of extending or completely replacing the Existing Power System.

The MCA Power Share feature provides for the sharing of the total load in a controlled manner.

When Power Share is programmed, the MCA in the New Power System adjusts Rectifier output voltage per load demands to ensure proper sharing between the New and Existing

Power Systems.

Operating Modes

Depending on the systems’ configurations, their Rectifier capacities, their distribution load capacities, and the Power Share configuration; four operating modes can occur.

Low Load Operation

When the total load current demand is lower than the programmed percentage value of the total capacity of the New Power System that will initially feed the load (PS Initial

Capacity Limit), the New Power System voltage will be increased by the programmed

PS Voltage Offset forcing the New 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 PS Initial Capacity Limit, the New

Power System output voltage will be decreased by the PS Voltage Offset, allowing the

Existing Power System to deliver the remaining current up to the New Power System’s maximum capacity. Both New and Existing Power Systems are now providing current to the load.

High Load Operation

When the total load current demand exceeds the sum of the maximum capacity of the

Existing Power System and the PS Initial Capacity Limit of the New Power System, the

New Power System will deliver the remaining current up to the maximum of its capacity.

The two systems will then reach their maximum capacities. This operation may occur when the batteries are being recharged, after a commercial AC failure for example.

Overload Operation

When the total load current demand is higher than the sum of the maximum capacity of the Existing Power System and the maximum capacity of the New Power System, both

Existing and New Power 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 PCUs (rectifiers) is too low in relation to the need for increased current.

Requirements and Conditions

The two DC power systems must be connected in parallel as described in the Installation

Instructions (Section 5776).

Verifying the Operation of the Power Share Feature

After programming the “Power Share” feature, verify its operation as follows. a) In a Power Share application where the New 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

New Power System over the “PS Initial Capacity Limit”.

1) Verify that the New Power System limits the total output of its (PCUs) rectifiers to the current equivalent to this programmed percentage.

2) Verify that the New Power System lowers its output voltage by the value of the programmed “PS Voltage Offset”.

3) Verify that the rectifiers in the Existing Power System take the additional load as the load increases pass the “PS Initial Capacity Limit”.

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 New Power System starts taking the additional load as soon as the total capacity of the rectifiers in the Existing Power

System is exceeded.

ADDING A BATTERY CHARGE DIGITAL TEMPERATURE

COMPENSATION PROBE TO A PREVIOUSLY OPERATED

SYSTEM

This procedure details the steps to add a Battery Charge Digital Temperature

Compensation Probe to a system that has been previously started, configured, and checked.

Procedure

1) Refer to the separate Installation Manual , “Chapter 3. Making Electrical

Connections ”, and mount the Battery Charge Digital Temperature Compensation

Probe near the batteries.

2) Refer to the separate Installation Manual , “Chapter 3. Making Electrical

Connections ”, and connect the Battery Charge Digital Temperature

Compensation Probe to the system. The MCA automatically detects the probe and adds it to the inventory without any alarms. The default slope setting is NO

TEMPERATURE COMPENSATION.

3) Refer to “Chapter 4. MCA System Adjustments” of these instructions, and set the following digital battery charge temperature compensation parameters: SLOPE,

MAXIMUM COMPENSATION, and MINIMUM COMPENSATION.

4) Refer to “Chapter 4. MCA System Adjustments” of these instructions, and set the following alarm parameters: HIGH TEMPERATURE #1 ALARM, HIGH

TEMPERATURE #2 ALARM, LOW TEMPERATURE #1 ALARM, and LOW

TEMPERATURE #2 ALARM.

5) Verify that battery charge temperature compensation has begun by comparing the SYSTEM voltage reading versus the FLOAT setting. Depending on the battery ambient temperature, the SYSTEM voltage should be higher or lower than the FLOAT setting by the amount of slope V/ºC (note that SYSTEM voltage will also vary from the FLOAT setpoint depending on the load).

Note: At 25ºC, the battery charge temperature compensated SYSTEM voltage equals the FLOAT voltage setting.

Note: If the probe is disconnected or fails, a major alarm (local and extended) activates and the system returns to the FLOAT voltage setting.
