6. Outdoor Power Troubleshooting and Maintenance
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

7. Outdoor Power Troubleshooting and Maintenance
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.
8. Outdoor Power Troubleshooting and Maintenance
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.
9. Outdoor Power Troubleshooting and Maintenance
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.
TA& TB1 sensor
10. Outdoor Power Troubleshooting and Maintenance
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.
