EXTERNAL ALARM, REFERENCE, MONITORING,
AND CONTROL CONNECTIONS
External alarm, reference, monitoring, and control connections are made to terminals of
TB1 and TB2 located on the system interface circuit card mounted on the inside of the
main shelf’s front door. Refer to Figure 4-2 for location.
External FA/CBA Alarm Input: An external FA/CBA alarm signal can be connected to the
system as described in the Expansion Shelf(s) Interconnections section.
External Alarm Relays
External alarm relays are extended to terminal block TB1 located on the system interface
circuit card. Relays are energized for normal operating conditions and de-energized for
an alarm condition.
Low Input Voltage Alarm: Alarms if a converter module reports a low input voltage
condition. A close loop circuit is provided between terminals 1 and 2 of TB1 and an
open loop circuit is provided between terminals 2 and 3 of TB1 during an alarm
condition.
Fuse / Circuit Breaker Alarm: Alarms if any distribution fuse or circuit breaker
opens. A close loop circuit is provided between terminals 4 and 5 of TB1 and an
open loop circuit is provided between terminals 5 and 6 of TB1 during an alarm
condition.
Converter Fail Major Alarm: Alarms if more than one converter module fails (or if
only one converter module is installed in the system and it fails). A close loop circuit
is provided between terminals 7 and 8 of TB1 and an open loop circuit is provided
between terminals 8 and 9 of TB1 during an alarm condition. Refer to the Operating
Procedures chapter for alarm conditions.
Converter Fail Minor Alarm: Alarms if one converter module fails. A close loop
circuit is provided between terminals 10 and 11 of TB1 and an open loop circuit is
provided between terminals 11 and 12 of TB1 during an alarm condition. Refer to the
Operating Procedures chapter for alarm conditions.
CAN Bus
An ACU+ can be connected to terminals 1 (CANL) and 2 (CANH) of TB2.
Output Current Signal Reference
The output current signal (also provided at the output current test points on the front door
of the main shelf) can be selected to be referenced to plus battery (input), referenced to
minus battery (input), or not referenced as detailed below. The output current signal can
be set at 1A/mV or 400A/50mV per CHAPTER 3. SETTING JUMPER AND SWITCH
OPTIONS.
Referenced to Plus Battery (input): Provide a jumper between terminals 4 (+BT)
and 5 (-IO) of TB2.
