Setting Door Opening Travel

(Continued)

NOTE: If door does not open fully and opener light flashes (make sure the bulb is installed and operating) check for an obstruction or see Adjustment #1, page 32 (Adjusting Opening Force).

To adjust for a non-standard door or to precisely set the open position: Using the wall station, operate the door and stop it in mid-travel position. Using a flathead screwdriver turn the OPEN travel adjuster for more (counter-clockwise) or less (clockwise) travel. A 1/4 turn equals approximately 1” of trolley movement.

NOTE: Confirm that the door has stopped in the UP position as a result of the upper limit switch and not because the trolley has hit the stop bolt, which is mounted in the rail near the opener. The correct condition can be verified by observing that the openers convenience light does not flash after the fully open door comes to a stop. The faulty condition may also be confirmed visually by checking to see if the trolley is resting against the stop bolt.

To confirm final OPEN travel adjustment, activate the opener to bring door to fully open position. The opener light should not be flashing.
