8-19. TEST SAFETY REVERSAL

The safety reversal function of your opener is an extremely important feature of your opener. Testing this function ensures the correct operation of your opener and door. The reversal system test should be performed:

■Once per month.

■Anytime the travel or force limits are reset or changed.

Once the adjustments have been set and the door has been run up and down twice to “learn” the new settings, you must test the reversal system for proper operation.

■Place a 1-1/2" high rigid object (or a 2x4 laid flat) on the floor directly in the path of the door. See Fig. 44.

■Start the door in the downward direction and watch what happens.

■When door contacts the object (or 2x4), it should stop, reverse, and automatically return to the fully opened position.

■If the door does not reverse, reset the down travel limit so that the door travels slightly further down in the closed direction. Then, retest the unit as described above.

■If the door still does not reverse, disconnect your opener and call a service person.

8-20. ALIGN AND TEST PHOTO EYES

ALIGNMENT:

Photo eyes maintain an invisible, unbroken beam between each unit. The eyes must be properly aligned for the system to function and provide the protection it was designed for. Follow these steps to insure proper alignment:

■When photo eyes are connected to the powerhead and the power is on, the green light on the transmitter photo eye will illuminate. When the eyes are aligned, the red light on the receiver eye will illuminate.

■Loosen the wing nut on each photo eye and rotate eye in holder as needed until eyes are aligned and the light on each photo eye is illuminated. See Figs. 45 and 46.

■Tighten the wing nut firmly by hand on each assembly to secure each photo eye in position.

SAFETY TEST:

Photo eyes installed on opposite sides of your door opening are intended to detect a person or object in the path of the door and prevent the door from moving downward. The following steps will determine if the system is functioning properly:

■Open door using the opener’s transmitter or wall control.

■Place a box or other object in the path of the door so it breaks the photo eye beam. See Fig. 46A. Red indicator light on receiver should go out.

■Press and release the wall control button. The door should not move in the down direction. LED #6 on the opener will flash. If this does not happen, disconnect opener and call for service.

■To reset opener, remove the obstruction and operate the door normally.

■If photo eyes are not aligned or are damaged, door can only be closed by pressing and holding wall control button until door is fully closed.
