3 - 6 Operation

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 Auxiliary Major Alarms
FAJ and AMJ are the controller primary alarm inputs. FAJ is
available at P-8 and J17-1 on the BUJ and TB4-6 on the alarm
terminal board. AMJ is available at J16-1 on the BUJ1 and TB4-
2 on the alarm terminal board. To create these alarms, the
respective alarm inputs must be connected to Bat or battery
voltage. This battery voltage typically has a series 1K ohm
resistor between Bat and the alarm input.
The operation of an output distribution fuse or circuit breaker
places battery voltage onto the FAJ input of the BUJ1 board,
activating the Major Fuse alarm.
Auxiliary Major on the BUJ1 board can be user-assigned for any
supplemental alarm monitoring for which a battery voltage
signal (through 1K ohms) can be obtained, which is asserted by
a signal to the AMJ terminal on the BUJ1 board.
