Galaxy Vector Controller GCM2, GCM3
Issue 4 January 2008 Operation 3 - 7
Rectifier ID Conflict Alarm
This alarm occurs when rectifier ID numbers are duplicated or
are zero. Refer to the rectifier manuals for setting and viewing
the rectifier ID numbers.
Rectifier Manual Off Alarm
Whenever the rectifier is manually turned to standby, this alarm
occurs. A switch on the front panel for each rectifier allows the
user to manually turn the rectifier on or standby. When the
switch is in standby position, the alarm is active.
Rectifier Phase Alarm
This alarm is for multiphase rectifier. When AC is lost in one or
more phase but not all phases, this alarm occurs.
Converter Failure and Multiple Converter Failure Alarm
Converter failure alarms are generated for various reasons.
These include failure in the converter, the converter is removed,
the converter interface board is removed, or communication is
lost with the converter interface board. The removed CFA is
cleared by updating the serial line in the Operations and Control
menu (see Configuration, Section 4).
Converter ID Alarm
This alarm occurs when converter ID numbers are other than 1
through 8, or are duplicated. Refer to the converter section of the
plant manual for setting and viewing ID numbers.
Converter Distribution Alarm
Any fuse or breaker open at the converter output side (-48v
distribution) causes this alarm.
Converter Fan Fail Minor and Converter Fan Fail Major
The converter carrier 597B has two fans. If one fan in a carrier
fails, the controller reports a Converter Fan Minor alarm. If both
fans fail, the controller reports a Converter Fan Major alarm.
Major and Minor Fuse and Auxiliary Alarms
To create these alarms, the respective alarm inputs must be
connected to Bat or battery voltage or, in the case of J27 on the
BTJ2/BTJ3 board, a connection between two terminals must be
made. This battery voltage typically has a series 1K ohm resistor
between Bat and the alarm input.
