Page 28

ADJUSTMENT STEP 1

Adjust the UP and DOWN Travel Limits

Limit adjustment settings regulate the points at which the door will stop when moving up or down.

To operate the opener, press the Door Control push button. Run the opener through a complete travel cycle.

•Does the door open and close completely?

•Does the door stay closed and not reverse unintentionally when fully closed?

If your door passes both of these tests, no limit adjustments are necessary unless the reversing test fails (see Adjustment Step 3, page 30).

Adjustment procedures are outlined below. Read the procedures carefully before proceeding to Adjustment Step 2. Use a screwdriver to make limit adjustments, Run the opener through a complete travel cycle after each adjustment.

NOTE: Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. Simply wait 15 minutes and try again.

NOTE: If anything interferes with the door's upward travel, it will stop. ff anything interferes with the door's downward travel (including binding or unbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE LIMITS

•If the door does not open completely but opens at least five feet:

Increase up travel. Turn the UP limit adjustment screw clockwise. One turn equals 2" of travel.

NOTE: Toprevent the trolley from hitting the cover protection bolt, keep a minimum distance of 2-4" between the trolley and the bolt.

•If door does not open at least 5 feet:

Adjust the UP (open) force as explained in Adjustment Step 2.

•If the door does not close completely: Increase down travel. Turn the down limit adjustment screw counterclockwise. One turn equals 2" of travel.

If door still won'tclose completely and the trolley bumps into the trolley stop bolt (see page 4 or 5), try lengthening the door arm (page 26) and decreasing the down limit.

•If the opener reverses in fully closed position:

Decrease down travel. Turn the down limit

adjustment screw clockwise. One turn equals 2" of travel.
