Step 21: Securing the Opener
IMPORTANT! - This infrared safety sen-
sor sends an invisible beam of light from
the sending unit to the receiving unit across
the pathway of the door. The door opener
will not operate until the safety sensor is
connected to the power unit and properly
aligned. If the invisible beam of light is ob-
structed, an open door cannot be closed by
the transmitter or a momentary activation of
the wall mounted push button. However, the
door may be closed by holding your fi nger
on the wall push button (constant pressure)
until the door travels to a fully closed posi-
tion. The safety sensors must be aligned by
moving the sending and receiving units in
or out (see Fig. 1) until the alignment light
on the receiving unit comes on. The
1/4-20” carriage bolt can be loosened to
move the unit in or out, as required. If you have diffi culty aligning beams, check that both brackets are mounted
at the same height and remount if necessary. Additional minor adjustments can be made by lightly bending the
mounting brackets (see Fig. 2).
WARNING FAILURE TO MAKE ADJUSTMENTS COULD RESULT IN SEVERE OR FATAL
INJURY.
Once the alignment light comes on, tighten all bolts and mounting screws. Finish securing all wire making sure
not to break or open any of the conductors. Loop and secure any extra wire.

NOTE: Good door balance and freedom of
movement are critical to the safety and perfor-
mance of the door opener. If door is very heavy
to lift or if springs are too tight making door hard
to close or if door sticks or binds in the track,
now is the time to correct it.
