Is there any foreign material
obstructing the fan propeller?
Does the fan rotate freely when it is
turned by hand?
Is there DC280V between (CNFAN
(red) - (blue) on the fan motor’s
connection?
Cut and reset the power source.
Has the fault been corrected?
Temporary surge on incoming
supply may have caused the alarm.
Replace the fan motor. (If the fault
persists, replace the control PCB.)
Is fuse F2 intact?
Check the power source.
Replace defective fan motor and
control PCB.
Replace the fan motor. If the
resistance between
(Vm):red-(GND):blue is 1 kΩ or
lower, the motor is defective.
Remove foreign material.
