(Sheet 3 of 3)

T009D

Is there voltage

across terminals 1 & 4 of

the cylinder motor?

Does the cylinder

motor run?

Correct the wiring

between the

cylinder motor and

control relay.

Replace cylinder

motor.

YES

Unit operational.

NOTE: For three phase high voltage (380 volts or

higher), the cylinder and fan motors are supplied L1, L2,

L3 through the motor relay terminals T1, T2, T3. Make

the appropriate voltage checks while doing trouble

shooting.
