FC overload

Warning

Description

FC Overload Warning

Cause

Indication of problems with compressor

Trouble

shooting

(W9)

Possible causes:

•

The FC cannot supply enough power to the compressor.

•

Insufficient cooling for the FC.

•

Defect FC.

Accompanied alarms:

•

AL 522 or AL 525 may also be active and should be checked first.

Trouble shooting:
At very high ambient temperatures and very low setpoint temperatures, the FC

may get too hot to generate enough power. It can therefore be cooled by the

refrigerant in the compressor.
1.

Check that all bolts fixing the FC to the compressor are fastened and nothing

is jammed between the FC and the compressor.

2. The power cable for the compressor motor (Mcpr) may have been mounted

incorrectly and therefore the cooling contact between the FC and the

compressor is not good enough. Check the motor cable and replace it if it is

defect. Fasten bolts properly for better cooling.

3. The compressor is wearing down and drawing increasingly power from the

FC. Check other alarms if there have been more alarms from the FC.
a. If the ambient temperature is not high, the compressor must be replaced.

b. If the ambient temperature is high, the compressor and FC should be ok

but close to operating limit. Monitor unit and see if problem continues.

4. The FC is defective and must be replaced.
If no FC replacement is available, the unit can be rewired for emergency

operation: See “Emergency Operation” p. 50

Criteria

FC load has exceeded warning limit of 24 Amp

Controller

action

None

Log

Alarm

Alarm light

Off

Consequence

If not solved, this problem can cause FC to stop due to AL 513

Elimination

Warning will be marked as inactive in alarm list when reset by FC. Alarm may then be

deleted.
