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 25
Step Action
1 Turn off AC circuit breaker feeding a single rectifier. 26
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 27
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.
25 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).
26 DC fed Eco rectifiers do not report a failure (INF) when DC input is removed.
27 Eco systems do not alarm for battery discharges and may have BD thresholds settings different than non-Eco
systems.
