Motor Fault
Fuse in the control has blown. A
short in a device on the PLC output
may have failed causing the fuse to
blow. A less likely scenario would
be a short in the motor wiring for the
boost motor or main motor.
Check the devices on the PLC outputs to determine what caused
the fuse to blow. If it is a failed solenoid, usually you will see
the plastic body deformed from heat. Check all cables for
damage. Replace any faulty parts.
The main motor thermal overload
(OL-MAIN) may have tripped.
Reset by pushing the reset button on the thermal overload. Refer
to
Electric Motors in the Electrical System section of this
manual.
