ACH/ACL/ AC Off Alarm

Check ACL/ACH alarm Setting. Verify the AC input voltage at the AC service panel by a multi-meter. To check whether commercial power problem or AC circuit breaker tripped causes the AC Fail. The AC circuit breaker should be tripped until the AC utility is repaired and the AC input is within input specifications.

Check AC detected CKT, please refer below:

Each Phases is 180~ 240Vac

DCH/DCL Alarm

Check DCL/DCH alarm Setting. Verify the output bus-bar voltage. If the output voltage is not within tolerance+/- 0.1Vdc. However, swap the rectifier with a spare module, and return the faulty unit to Delta Products for repair. If the output of each rectifier is within tolerance, check the controllere parameters to ensure the correct FL/EQU settings.

Load/Battery Breaker Trip Alarm

If the circuit breaker continues to fail:

Check trip load side still short or over rating.

Check the DC Branch load (fed by the DC circuit breaker) to ensure the circuit breaker is the correct rating. If the branch load exceeds the circuit breaker rating, the circuit breaker must be changed to a higher rating.

Swap with a spare circuit breaker with a higher rating.

Temperature/Humidity Alarm or Sensor Lose

This alarm is generated when the threshold temperature set in parameter alarm setting TA/Tb1 is exceeded and also controls the Temperature Compensation Voltage Control. The CSU senses the temperature via sensor TA/Tb1 and generates an Ambient Over Temperature Alarm setting TA/Tb1.

Rectifier Failure Alarm

When a rectifier fails, the alarm information is sent to the CSU and the rectifier is shut down. The rectifier should be swapped out with a spare unit and the faulty unit returned to Delta for repair.

Warning! Do not open the rectifier module. There are no serviceable parts. Call Delta Customer Service for a RMA number for repair and return.
