the garage door opener. The red light on the
receiver unit should now be on. If not, recheck
that the mounting screws are tight then, if
necessary, align the photosystem by slightly
bending the wall bracket until proper operation
is obtained.
B.
Place an object (packing insert box or a similar
object approximately six inches high) one foot in
front of the transmitter or receiver. The red LED
should go OFF and remain OFF until the object
is removed. NOTE: There may be a slight delay
in returning to normal depending upon how long
Important Test: Photoelectric
Obstruction Test
Test Procedure
Place an object 6" x 12" on the floor (as
illustrated) progressively on foot from the left
side of the door; center of the door and one foot
from the right side of the door. The object must
prevent an open door from closing in any other
mode other than constant pressure on the wall
button. The object should also cause a closing
door stop and reverse to the open position. If it
