28 Adjustment Step 2 Adjust the Force Force adjustment controls are located on the right side 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. Weather conditions can affect the door movement, so occasional adjustment may be needed. The maximum force adjustment range is 260 degrees, about 3/4 of a complete turn. Do not force controls beyond that point. Turn force adjustment controls with a screwdriver. Adjustment Label Too much force on the door 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. Do not increase the force beyond the minimum amount required to close the door. Do not use the force adjustments to compensate for a binding or sticking garage door. Test the safety reverse system following all adjustments to force levels. See page 30. Force Adjustment Controls 000 Right Side Panel How and When 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 two-inch obstruction. See page 30. If the door is hard to hold or doesn't reverse, decrease the DOWN (close) force by turning the control counterclockwise. Make 10 degree turn adjustments until the door reverses normally. After each adjustment, run the opener through a complete cycle. 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. to Adjust the Forces Make 10 degree turn adjustments until the door stops easily. 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 10 degree turn adjustments until door opens completely. Re-adjust the UP limit if necessary. After each adjustment, run the opener through a complete travel 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 10 degree turn 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. 29 Adjustment Step 3 Test The Safety Reversing Sensor • Press the remote control push button to open the door. • Place the opener carton in the path of the door. • Press the remote control push button to close the door. The door will not move more than an inch, and the opener light(s) will flash. Professional service is required if the opener closes the door when the safety reversing sensor is obstructed. The garage door opener will not close from a remote control if the indicator light in either sensor is off(alerting you to the fact that the sensor is misaligned or obstructed). The garage door can be closed by pressing and holding the Wall Control push bar until down travel is completed. Adjustment Step 4 Test the Safety Reverse System Test: • Place a one-inch board (or a 2x4 laid flat) on the floor, centered under the garage door. • Operate the door in the down direction. The door must reverse on striking the obstruction. Adjustment: If the door stops on the obstruction, it is not traveling far enough in the down direction. • Increase the DOWN limit by turning the DOWN limit adjustment screw counterclockwise 1/4 turn. • Repeat the test. On a sectional door, make sure limit adjustments do not force the door arm beyond a straight up and down position. See the illustration on page 26. • When the door reverses on the one-inch board, remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment. If the door will not reverse after repeated adjustment attempts, call for professional garage door service. Without a properly working safety reversing sensor, persons (particularly children) could be seriously injured or killed if trapped by a closing garage door. Repeat this test once a month, Safety Reversing Sensor Safety Reversing Sensor Failure to test and adjust the safety reverse system may result in serious injury or death to persons trapped by a closing garage door. Repeat this test once a month and adjust as needed.
