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.
