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
26
Step Action
1
Turn off AC circuit breaker feeding a single rectifier.
27
2
Verify ACF – AC Fail Minor is reported for the correct rectifier ID.
3
Restore input and verify alarms clear and the controller returns to Normal.
4
Remove input from two or more rectifiers.
5
Verify MACF – Multiple AC Fail Major is reported for the correct rectifier IDs.
6
Turn on input circuit breaker turned off in Step 1 and verify alarms clear and the controller returns to
Normal.
Battery On Discharge Alarms
28
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
Verify the BD alarm occurs when the system voltage decreases to BD threshold.
4
Verify the BD alarm clears once the voltage has exceeded 0.5V above the BD alarm threshold.
5
Restore the BD alarm threshold to its previous setting.
High Voltage Alarms
Step Action
1
Confirm the HV alarm threshold (Menu > Configuration > Float Settings > Voltage Alarms > High Minor).
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.
26
Rectifier Input Fail Controller Alarms: is displayed and labeled “ACF” and “MACF”.
Input Fail Rectifier LED: non-Eco rectifiers LED is labeled “ACF”. Eco rectifiers LED is labeled “INF” (INput Fail).
27
DC fed Eco rectifiers do not report a failure (INF) when DC input is removed.
28
Eco systems do not alarm for battery discharges and may have BD thresholds settings different than non-Eco systems.
