Testing Additional
Alarms
Alarm operation may be verified while the system operates at float
voltage.
Testing the BD
Alarm and High
Voltage Shutdown
For additional information about the High Voltage Shutdown
feature
and test, consult the Galaxy controller product manual.
Testing Additional Alarms
Step
Action
1
Turn OFF the ac circuit breaker of rectifier #1. Verify that the
AC and MIN alarm LEDs illuminate, the rectifier displays
ACF, and the controller alarms screen indicates RECTIFIER
FAIL : G01 (Millennium controllers) or rFA: (Vector
controllers).
2
Turn ON the ac circuit breaker of rectifier #1. Verify that the
rectifier starts and the alarms retire.
3
Simulate a load circuit breaker alarm by shorting the alarm
contacts on the circuit breakers or inserting an operated alarm
fuse. Verify that the DIST and MAJ alarm LEDs illuminate and
the controller alarms screen indicates EXTERNAL FUSE
MAJOR (Millennium controllers) or FAJ (Vector controllers).
Testing the BD Alarm and High Voltage Shutdown
Step
Action
1
Set the system load to 25 amperes.
2
Turn all rectifiers to STBY.
3
As the system voltage drops, observe that the BD alarm
activates at the programmed BD threshold.
4
Turn ON a single rectifier after the BD activates. Observe that
the BD retires as the system voltage rises above the BD
threshold.
5
Turn ON the remaining rectifiers and increase the system load
until all rectifiers have a minimum of 25 amps. Increase the
system voltage to the HV level. (The HV factory default is
55.0V.) Verify that the rectifiers shut down.
6
Immediately after the rectifiers shut down, return the system to
the float voltage. Verify that the rectifiers restart.
