Clutch Adjustment Fig. 14
The Trolley Operators have a friction style clutch that can be adjusted.
NOTE: The clutch is intended to provide protection for the door, the operator
and associated equipment. It is not intended for entrapment protection.
These 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. Therefore,
the adjustment of the clutch should be such that the door and operator function
in this manner. The steps for clutch adjustment follow:
Adjusting the Clutch
The GT™ Clutch does not require any disassembly to adjust.
1) All adjustments should be made in very small amounts
(e.g. turning adjustment bolts 1/4 turn at a time).
2) When making adjustments, be sure to turn all 3 adjustment
bolts an equal amount. Fig 12.
— To increase tension, turn adjustment bolts clockwise.
— To decrease tension, turn adjustment bolts
counter-clockwise.
3) Clutch needs to be agjusted to a tension just above what is
required to open and close door without clutch slippage.

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.
