FCC INFORMATION
The MCA Interface Modem Option (if installed) has been granted a registration number by the Federal
Communications Commission, under Part 68 rules and regulations for direct connection to the telephone lines. In
order to comply with these FCC rules, the following instructions must be carefully read and applicable portions
followed completely:
a) Direct connection to the telephone lines may be made only through the standard plug- ended cord
furnished to the utility-installed jack. No connection may be made to party or coin phone lines. Prior to
connecting the device to the telephone lines, you must:
b) Call your telephone company and inform them you have an FCC registered device you desire to connect
to their telephone lines. Give them the number(s) of the line(s) to be used, the make and model of the
device, the FCC registration number and ringer equivalence. This information will be found on the device
or enclosed with instructions as well as the jack suitable for your device.
c) After the telephone company has been advised of the above you may connect your device if the jack is
available, or after the telephone company has made the installation.
d) Repairs may be made only by the manufacturer or his authorized service agency. Unauthorized repairs
void registration and warranty. Contact seller or manufacturer for details of permissible user performed
routine repairs, and where and how to have other than routine repairs.
e) If, through abnormal circumstances, harm to the telephone lines is caused, it should be unplugged until it
can be determined if your device or the telephone line is the source. If your device is the source, it should
not be reconnected until necessary repairs are effected.
f)

Should the telephone company notify you that your device is causing harm, the device should be
unplugged. The telephone company will, where practicable, notify you, that temporary discontinuance of
service may be required. However, where prior notice is not practicable, the telephone company may
temporarily discontinue service, if such action is reasonably necessary, in such cases the telephone
company must (A) Promptly notify you of such temporary discontinuance, (B) Afford you the opportunity
to correct the condition and (C) Inform you of your rights to bring a complaint to the FCC under their rules.

g) The telephone company may make changes in its communications facilities, equipment, operations or

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

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

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.

Method 3 (Automatic Test/Equalize) Procedure
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.
1) With SYSTEM OK being displayed on the MCA Interface Pad, press and release
the FUNCTION SET ENTER key. The FUNCTION MENU is displayed.
or
In the MAIN ALARM MENU, repeatedly press and release the FUNCTION
SELECT DOWN arrow key until "GO TO FUNCTION MENU" is displayed. Press

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.
4) Press and release the ALARM CUTOFF and FUNCTION SET ENTER keys
simultaneously.
5) Press the FUNCTION SET YES (+) or FUNCTION SET NO (-) key until the

Method 4 (External Test/Equalize) Procedure
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.

MCA “POWER SHARE” FEATURE
Description
The MCA Power Share feature allows you to connect a Spec. No. 582140000 Power
System (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).

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.

ADMONISHMENTS
General Safety
Danger: SERVICE PERSONNEL MUST FOLLOW APPROVED SAFETY
PROCEDURES.
Performing the following procedures may expose service personnel to
hazards. These procedures should be performed by qualified service
personnel 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 insulated tools.
(To avoid danger to the installer or damage to the equipment, the
tools used in this procedure should have insulated grips. All exposed
metal shafts, extensions, handles, etc. should be completely insulated
with a minimum of three half-lapped layers of electrical tape. Ensure
that wrenches with more than one working end have only one end
exposed.)

Voltages
AC Input Voltages
Danger: This system operates from AC voltage capable of producing fatal
electrical shock.
DC Input/Output Voltages
Danger: This system produces DC Power and requires battery to be connected to
it. Although the DC voltage is not hazardously high, the rectifier modules
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.

ADDING A RECTIFIER
To increase system current capacity, an additional Rectifier can easily be installed in an
existing bay that contains an empty Rectifier mounting position. Follow the procedure
detailed below. A Rectifier may be installed in a live system.
The Rectifier weighs approximately 40 lbs.
Rectifiers can be inserted or removed with power applied (hot swappable).
Procedure
1) Remove the blank panel from the Rectifier mounting position. Save this panel.
The panel must be re-installed if a Rectifier is removed.
2) Ensure that the Standby/Operate switch on the Rectifier to be installed is in the
"standby" position.
Note: In the next step, a safety latch is present on the left-hand (as viewed from the
front) side panel of each Rectifier. The latch is designed to prevent the
Rectifier from inadvertently being removed completely from the Bay once it
has been installed. It should not be necessary to depress the safety latch
release when installing the Rectifier.
3) Install the Rectifier into the bay by sliding it evenly into its mounting position.
Secure the Rectifier to the bay by tightening the captive fasteners on the
Rectifier.
4) Place the Standby/Operate switch on the Rectifier installed to the I "operate"
position.
5) The MCA automatically adds the capacity of the new Rectifier to the current limit
and displays the new current limit setting.
6) If the current limit setting is correct, go to step 10). If the current limit setting is
not correct, press and release the ALARM CUTOFF and FUNCTION SET
ENTER pushbuttons simultaneously.
7) Observe the value displayed. This is the system current limit setting. Reset this
value to the new current limit setting. Each Rectifier’s current limit circuit will be
automatically adjusted to ensure that system current does not exceed this value.
To change this value, press and hold the FUNCTION SET YES (+) or NO (-)
pushbutton. Release the pushbutton when the desired value is displayed.
8) With the desired current limiting value being displayed, press and release the
FUNCTION SET ENTER pushbutton.
9) “ARE YOU SURE?” is displayed. Press and release the FUNCTION SET YES
(+) pushbutton.
Note: The system current limit value will not be changed and the adjustment
mode will be exited if the FUNCTION SET YES (+) pushbutton is not
pressed within 10 seconds of the “ARE YOU SURE?” prompt.
10) Press and release the FUNCTION SET YES (+) and NO (-) pushbuttons
simultaneously, to return to the beginning of the MCA menu tree.
11) Ensure that there are no local or remote alarms activated on the system.

TROUBLESHOOTING INFORMATION
General
This system is designed for ease in troubleshooting and repair. The various indicators,
as described in Chapter 3. System Operating Procedures, are designed to isolate a
failure to a specific element. Once the faulty element has been identified, refer to the
next sections, “Replacement Information” and "Replacement Procedures".
The procedures listed in Chapter 5. System Maintenance, can also be used by servicing
personnel in identification and/or prevention of trouble symptoms in the system.

Adjustments
If the suspected cause of a trouble symptom is an out of adjustment condition, that
particular adjustment setting should be checked or reset using the appropriate
adjustment procedure detailed in Chapter 4. MCA System Adjustments. If a failed
Rectifier or circuit card is suspected, the adjustment procedures can also be used to
verify the setpoints as well as the operation of the Rectifier or circuit card.

MCA Messages
An MCA Menu Tree (Section 5886) is provided in the separate INSTALLATION MANUAL
and the CD CARRIER MANUAL (it is also provided on the CD). Each line in the MCA
Menu Tree contains a number. This number is referenced in a chart provided in Chapter
2. Navigating the MCA. This chart provides a description of each line listed on the MCA
Menu Tree.
If the MCA displays an alarm message, find the line in the MCA Menu Tree showing this
message. For an explanation of this alarm, locate the corresponding MCA Menu Tree
Line Number in the chart provided in Chapter 2. Navigating the MCA.
Note: If the MCA is replaced with an MCA previously used in another power system, the
MCA may reflect inventory items not in the current power system and may display
alarms. In this case, update the inventory as detailed in this chapter. Also, if you
remove an inventory item (a component) from the power system, you must update
the inventory to clear alarms.
Note: If you remove a Battery Charge Digital Temperature Compensation Probe, alarms
are displayed. Manually set the Battery Charge Digital Temperature
Compensation feature to off as described in "Chapter 4. MCA System
Adjustments" to clear the alarms.

REPLACEMENT PROCEDURES
Rectifier Replacement
Danger: Observe the instructions on top of the Rectifier as you remove it.
Note: If a Rectifier is removed without being replaced, perform the UPDATE
INVENTORY procedure found in this chapter to clear alarms.
The Rectifier weighs approximately 40 lbs.
Rectifiers can be inserted or removed with power applied (hot swappable).
Procedure
1) Observe the admonishments presented at the beginning of this chapter, and
those encountered in this procedure.
2) Performing this procedure may activate external alarms. Do one of the following.
If possible, disable these alarms. If these alarms cannot be easily disabled,
notify the appropriate personnel to disregard any future alarms associated with
this system.
3) On the Rectifier to be removed, place the Standby/Operate switch to the
"standby" position.
Note: In the next step, a safety latch is present on the left-hand (as viewed from the
front) side panel of each Rectifier. The latch is designed to prevent the
Rectifier from inadvertently being removed completely from the Bay once it
has been installed. It should not be necessary to depress the safety latch
release when installing the Rectifier.
4) Loosen the captive fasteners on the front of the Rectifier to be removed. Use the
handle provided on the front of the Rectifier, and pull the Rectifier out until it is
stopped by a safety latch located on the left-hand side panel of the Rectifier.
Refer to Figure 6-1 for latch and release location. Depress and hold the latch
release, and remove the Rectifier from the shelf. Support the bottom of the
Rectifier as you pull it out. Observe the instructions on top of the Rectifier as
you remove it.
5) Ensure that the Standby/Operate switch on the replacement Rectifier is in the
"standby" position.
6) Slide the replacement Rectifier evenly into its mounting position. It should not be
necessary to depress the safety latch release. Secure the Rectifier to the bay by
tightening the captive fasteners located on the Rectifier.
7) Place the Standby/Operate switch on this Rectifier to the I "operate" position.
8) Enable the external alarms, or notify appropriate personnel that this procedure is
finished.
9) Ensure that there are no local or remote alarms active on the system.

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.
