[. . . ] Limit adjustment settings regulate the points at which the door will stop when moving up or down. The door will stop in the up direction if anything interferes with door travel. The door will reverse in the down direction if anything interferes with the door travel (including binding or unbalanced doors). · 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 page 26). Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. Use a screwdriver to make limit adjustments. WARNING Improper adjustment of the travel limits will interfere with the proper operation of the safety reverse system. The door might not reverse properly when required and could seriously injure or kill someone under it. Test the safety reverse system following all adjustments to the travel limits. See page 26. 2-4" Left Side Panel Cover Protection Bolt INCREASE INCREASE UP DOWN TRAVEL TRAVEL Limit Adjustment Screws INCREASE INCREASE DOWN UP TRAVEL TRAVEL Limit Adjustment Label Limit Adjustment Label How and When to Adjust the Limits · If the door does not open completely but opens at least five feet: Increase up travel. NOTE: To prevent 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 door still won't close completely and the trolley bumps into the pulley bracket (see page 4 or 5), try lengthening the door arm. (See page 22. ) If you have adjusted the door arm to the maximum length and the door still will not close completely, lower the header bracket. · If the opener reverses in fully closed position: Decrease down travel. · If the door reverses when closing and there is no visible interference to travel cycle: If the opener lights are flashing, the Safety Reversing Sensors are either not installed, misaligned, or obstructed. If the door is not binding or unbalanced, adjust the DOWN (close) force. See Adjustment Step 2. 24 Adjustment Step 2 Adjust the Force Force adjustment controls are located on the right panel of the opener. Force adjustment settings regulate the amount of power required to open and close the door. The door will stop in the up direction if anything interferes with its travel. The door will reverse in the down direction if anything interferes with its travel (including binding or unbalanced doors). If the forces are set too light, door travel may be interrupted by nuisance reversals in the down direction and stops in the up direction.
