CORRECTIVE ACTIONS
Line contactor opens
CORRECTIVE ACTIONS
Check the slave control for stored fault
codes.
Verify the connection between P21 of the
master control and P10 of the slave control.
CAUSE OF STATUS INDICATION
This status code will be displayed when the field
transistor exceeds its specific current limit.
The line contactor will drop out and the key switch will
have to be recycled to restart the control.
