Adjustment Procedures for One-Piece Doors

Open Door Adjustment:

Decrease UP limit

•Turn the UP limit adjustment screw counter- clockwise 5-1/2 turns.

•Press the Door Control button/push bar. The trolley will travel to the fully open position.

•Manually raise the door to the open position (parallel to the floor), and lift the door arm to the trolley. The arm should touch the trolley just in back of the door arm connector hole. Refer to the fully open trolley/door arm positions in the illustration. If the arm does not extend far enough, adjust the limit further. One full turn equals 2" of trolley travel.

Closed Door Adjustment:

Decrease DOWN limit

•Turn the DOWN limit adjustment screw clockwise 5 complete turns.

•Press the Door Control button/push bar. The trolley will travel to the fully closed position.

•Manually close the door and lift the door arm to the trolley. The arm should touch the trolley just ahead of the door arm connector hole. Refer to the fully closed trolley/door arm positions in the illustration. If the arm is behind the connector hole, adjust the limit further. One full turn equals 2" of trolley travel.

Connect the door arm to the trolley.

•Close the door and join the curved arm to the connector hole in the trolley with the remaining clevis pin. It may be necessary to lift the door slightly to make the connection.

•Secure with a ring fastener.

•Run the opener through a complete travel cycle. If the door has a slight "backward" slant in full open position as shown in the illustration, decrease the UP limit until the door is parallel to the floor.
