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 circuitbreaker 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.


8/14


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 parameteralarm 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

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 andreturn.

Air Filter Maintenance - 2

The system is equipped with one piece of the filter on the door.

To remove the filter, pull out the filter from slot and than, re-install the new

one by push in to the slot.
