4. Replace X3. Remove the contactor X312
32
and measure the resistance of the contactor
with the motor cabling between X312:T1-T2.
Contact
Internal error in the thermal sensor of the motor
controller detector.
5. Switch of the wall-mounted power switch. Undo
33
the contactor at X3 on the motor. Use an ohmmeter to
measure the resistance towards the motor. Measure
between 1-2, 1-3, and 2-3. Correct resistance should be:
W4400H W600H W850H, W1100H
cold motor 0,84 ohm 0,68 ohm
hot motor 1,1 ohm 0,9 ohm
Correct resistance
Troubleshoot the cabling between the motor and motor
controller.

controller and motor.
Inspect the cabling and
replace if necessary.
0,48 ohm
