Master/Second Operation: Make sure that the master/second wiring is

 

 

installed correctly and is intact (not damaged).

 

 

 

 

Low or no high voltage power.

Measure the incoming voltage at the unit’s on/off switch. It should be

 

 

within 5% of the operator’s rating when running. Make sure that the

 

 

proper wire gauge was used for the distance between breaker and

 

 

operator by consulting the wiring specifications section on page 14 of

 

 

this manual.

 

 

 

 

Low or no low voltage power.

Measure the voltage at terminals R1 & R2 in the operator. This

 

 

voltage should be within 5% of 24 Vac. If the high voltage power is

 

 

good and the low voltage power is bad, check transformer wiring and

 

 

replace transformer.

Check the number of amps currently being drawn from the panel,

 

 

make sure that the total power being drawn does not exceed the

Problem in the motor.

Perform a visual inspection of the motor. Examine the motor’s labels

 

 

for any distortion or signs of over heating. Replace the motor if it is

 

 

humming, grinding or making excessive noise. NOTE: Repeated motor
