Curved Door Arm On one-piece doors, before connecting the door arm to the trolley the travel limits must be adjusted.
Adjustment Adjustment Section: Pages 28 - 30 Step 1 Adjust the UP and DOWN Limits Do not make any limit adjustments until the safety reversing sensors are completely installed. 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).
Adjustment Adjust Step 2 I I the Force 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.
Adjustment Step 3 Test The Safety Reversing Sensor L 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 will flash. Professional service is required if the opener closes the door when the safety reversing sensor is obstructed.
