Note: Wiring options are provided to lockout changing Power System

adjustment/configuration/ calibration settings locally and/or remotely.

In addition, the Ethernet Interface Option provides a Web-Browser Interface. The following

software options are also available.

SNMP Interface: Provides an Ethernet port for MCA connection into a TCP/IP network and

support for SNMP V2 (Simple Network Management Protocol). Communications to and from

the MCA is accomplished via a MIB (Management Information Browser). SNMP Traps are

provided for alarms listed on the MCA Menu Tree under the "Alarms Menu".

Battery Monitoring: Provides Battery Monitoring via the Web Browser Interface.

1.3.2 Remote On/Off (TR): The operation of any or all Rectifier Modules (PCUs) can be inhibited

(TR) via the WinLink option, the Ethernet option, or from the MCA front panel accessed interface

pad.

1.3.3 MCA Local Display: Provides digital metering of system load voltage and current, individual

Rectifier Module (PCU) current, subsystem load voltage and current (if subsystem installed), and

load current of subsystem, system, and/or battery shunts. Also displays system alarm

messages and adjustment information, as detailed in Section 1.3.10 "MCA Display".

The MCA contains a "Power Down" mode. The MCA turns off its display and PCU

communications to conserve power when system voltage falls below 20 volts. Full operation is

restored when system voltage recovers to 23.5 volts. The display and communications can be

temporarily reactivated by the user.

1.3.4 MCA Meter Accuracy: ±0.01 V, ±0.005% / °C

1.3.5 MCA Universal Adjustment Circuit: Provides single point control of float output voltage,

test/equalize output voltage, high voltage shutdown, and current limit adjustments.

Note: If the MCA should fail, the Rectifier Modules remember the float and high voltage

shutdown settings last delivered by the MCA. The current limit setting of each Rectifier

Module goes to 100% of full load rating.

Provides adjustments for all MCA alarm and control circuits. Adjustment ranges and factory

settings as follows.

All adjustments can be performed locally via the MCA front panel accessed interface pad, and

most can be performed remotely via the WinLink option or the Ethernet (Web-Browser Interface)

option.

(A) Rectifier Module Output Voltage:

(1) Without Battery Charge Temperature Compensation: Float voltage is adjustable

(2) With Battery Charge Digital Temperature Compensation Probe or TXM (multiple

from 23.50 to 28.50 volts DC. Test/equalize voltage is adjustable from 23.00 to 28.50

volts DC. The output voltage temperature coefficient does not exceed 0.01% per

degree centigrade from -40°C to +65°C. Factory set as follows unless otherwise

specified.

Power System List No.

MCA Configuration No.

Factory Setting (Volts)

probe concentrator module): With an optional battery charge digital temperature

compensation probe or TXM installed, the MCA automatically increases or decreases

the output voltage as battery ambient temperature decreases or increases, respectively.

The float and test/equalize voltage range is the same as without battery charge digital
