Miscellaneous Alarms (Batteries must be connected)
Distribution Alarms
Step Action
1.
Manually connect a piece of wire from the circuit breaker feed bus to the distribution alarm
strip.
2.
Verify an FAJ – Fuse Alarm Major is reported by the controller.
3.
Remove the wire. Verify the alarm clears.
Repeat test for each distribution panel or sub-system.
ac Fail Alarms
Step Action
1. Turn off ac circuit breaker feeding a single rectifier.
2.
Verify ACF – ac Fail Minor is reported for the correct rectifier ID.
3.
Restore ac and verify alarms clear and the controller returns to Normal.
4.
Remove ac from two or more rectifiers.
5. Verify MACF – Multiple ac Fail Major is reported for the correct rectifier IDs.
6. Turn on all ac circuit breakers and verify alarms clear and the controller returns to Normal.
Battery On Discharge Alarms (Batteries Connected)
Step Action
1.
Change BD alarm to 2 volts below float voltage (MENU > CONFIGURATION > FLOAT
SETTINGS > VOLTAGE ALARMS > BD).
2. Adjust the load to 50 amperes.
3. Turn off ac to the system.
4. Verify the BD alarm occurs when the system voltage decreases to BD threshold.
5.
Verify the BD alarm clears once the voltage has exceeded 0.5V above the BD alarm threshold.
6.
Restore the BD alarm threshold to its previous setting.
High Float Voltage Alarms (No Load)
Step Action
1.
Confirm the HV alarm threshold (MENU > CONFIGURATION > FLOAT SETTINGS >
VOLTAGE ALARMS > HIGH).
2.
Adjust the float voltage to a value greater than this threshold (MENU > CONFIGURATION
> FLOAT SETTINGS > SET POINT).
3. Verify an HV alarm is reported by the controller.
4. Restore the float voltage back to its original setting.
5.
Restore the HV setting back to its original setting.
6.
Verify the alarms clear and the controller returns to Normal.
