operators have a motor reversing feature that is integrated with the clutch
assembly. If an obstruction is placed in the pathway of the door during operation
the motor will stop and reverse when the clutch begins to slip.
The adjustment of the clutch should be such that the door and operator function in
this manner. The steps for clutch adjustment follow:
To Adjust the Clutch
1) Decrease the compression on the clutch until the operator will not lift
the door.
•
Turn the adjusting castle nut counter-clockwise to decrease clutch
compression and clockwise to increase clutch compression.
2) After completing step 1, begin to increase compression on the
clutch until the operator is capable of lifting the door through the
complete cycle without clutch slippage.
3) Test the reversing feature of the operator by placing an obstruction
under the door during a close cycle. The door should reverse on the
obstruction and return to the open position. If the door does not
close but comes down part way and reverses without any
obstructions in its path, then increase the clutch compression until
the door will close fully.
4) Finally, insert the cotter pin through the castle nut and shaft and bend
the outer leg of the cotter pin.
NOTE:
Periodically check the system for proper clutch action. If clutch starts to slip after
working properly for some time, check manual operation of door BEFORE adjusting
clutch. The door may not be operating freely or the counterbalance spring may
need adjusting. Repairs and adjustments must be performed by a trained service
representative using proper tools and instructions.
