Galaxy Vector Controller GCM2, GCM3
Issue 4 January 2008 Troubleshooting 5 - 3
Temperature
Probe Alarm is
present
The Temperature Probe Fail alarm indicates that either there is
something wrong with the temperature connections, or that there
is a problem with one of the external temperature processing
units. An additional possibility is that the alarm is indicating that
the thermal compensation feature is enabled, and that no
temperature probes are present. If there are no temperature
probes connected to the Vector, then disable the Battery Thermal
Compensation Enable setting.
Unexplained
Rectifier Failure
Alarm and
Multiple Rectifier
Failure Alarm
A rectifier that is removed from the plant will generate a
Rectifier Fail Minor alarm. If more than one rectifier is missing,
a Multiple Rectifier Fail Major alarm is generated. To clear these
alarm conditions, go to the Operation Menu and assert the
Update Serial Link (USL) command.
Note: A few minutes after executing Update Serial Link function
to clear alarms, the controller RFA alarm should clear and no
rectifier should display any alarms. If alarms continue to be
displayed, continue investigating the system for possible
rectifier problems.
Unexplained
Converter Failure
Alarm and
Multiple
Converter Failure
Alarm
A converter that is removed from the plant will generate a
Converter Fail Minor alarm. If more than one converter is
missing, a Multiple Converter Fail Major alarm is generated. To
clear these alarm conditions, go to the Operation Menu and
assert the Update Serial Link (USL) command.
Note: A few minutes after executing Update Serial Link function
to clear alarms, the controller CFA alarm should clear and no
rectifier should display any alarms. If alarms continue to be
displayed, continue investigating the system for possible
converter problems.
