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. If 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: 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 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't close completely and the trolley bumps into the pulley bracket (see page 4 or 5), try lengthening the door arm (page 22) 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. WARNING Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. • Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system. • If one control (force or travel limits) is adjusted, the other control may also need adjustment. • After any adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with one-inch high object (or 2x4 laid flat) on floor. CAUTION To prevent damage to vehicles, be sure fully open door provides adequate clearance. LEFT PANEL Travel Limit Adjustment ScrewsCover Protection Bolt 2-4" Adjust Adjust DOWN Travel UP 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. See Troubleshooting, page 19. Test the door for binding: Pull the emergency release handle. Manually open and close the door. If the door is binding or unbalanced, call for a trained door systems technician. If the door is balanced and not binding, adjust the DOWN (close) force. See Adjustment Step 2. 24 ADJUSTMENT STEP 2 ADJUSTMENT STEP 2 Force adjustment controls are located on the right panel of the motor unit. Force adjustment settings regulate the amount of power required to open and close the door. 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. Weather conditions can affect the door movement, so occasional adjustment may be needed. The maximum force adjustment range is about 3/4 of a complete turn. Do not force controls beyond that point. Turn force adjustment controls with a screwdriver. NOTE: If anything interferes with the door’s upward travel, it will stop. If anything interferes with the door’s downward travel (including binding or unbalanced doors), it will reverse. HOW AND WHEN TO ADJUST THE FORCES 1. Test the DOWN (close) force • Grasp the door bottom when the door is about halfway through DOWN (close) travel. The door should reverse. Reversal halfway through down travel does not guarantee reversal on a one-inch obstruction. See Adjustment Step 3, page 26. If the door is hard to hold or doesn't reverse, DECREASE the DOWN (close) force by turning the control counterclockwise. Make small adjustments until the door reverses normally. After each adjustment, run the opener through a complete cycle. • If the door reverses during the down (close) cycle and the opener lights aren't flashing, INCREASE DOWN (close) force by turning the control clockwise. Make small adjustments until the door completes a close cycle. After each adjustment, run the opener through a complete travel cycle. Do not increase the force beyond the minimum amount required to close the door. 2. Test the UP (open) force • Grasp the door bottom when the door is about halfway through UP (open) travel. The door should stop. If the door is hard to hold or doesn't stop, DECREASE UP (open) force by turning the control counterclockwise. Make small adjustments until the door stops easily and opens fully. After each adjustment, run the opener through a complete travel cycle. • If the door doesn’t open at least 5 feet, INCREASE UP (Open) force by turning the control clockwise. Make small adjustments until door opens completely. Readjust the UP limit if necessary. After each adjustmen...
