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.

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.
