(contactor closed)
5. Overload relay
6. Motor terminals
X5 jumper on interface board must
be set to electric position
Check that X5 jumper is in electric
(left) position
Defective phase detect module
Check:
1. D/E LED (Electric On) should be
on
2. Motor Contactor MCA or MCB
should be energized
Replace phase detect module as
needed
Defective motor contactor
Repair or replace motor contactor
Overload relay tripping
Check for shorted motor windings or
wires
Control circuit fuse open
Replace fuse and reset alarm codes
