STATUS CODE

DESCRIPTION OF

STATUS

CAUSE OF STATUS INDICATION

-65

The line coil current is too high
during the run mode

This status code will be displayed when the current limit in the line
coil is exceeded during the run mode. The line contactor will drop
out and the key switch will have to be recycled to reset the control.

MEMORY RECALL

YES

SYMPTOM
Control will not operate.

POSSIBLE CAUSE

- Shorted line contactor coil
- Short between wires connected to
line coil (wires #10 and 24)

If line coil resistance is correct:
Defective control.

=

Replace controller unit.
