Step 22: Alignment of the Wireless Infrared Safety Sensors
Use the following instructions if your opener is equipped with Wireless Infrared Safety Sen-
sors. If your opener is equipped with Wired Infrared Safety Sensors proceed to step 23.
IMPORTANT: This infrared beam sensor sends an invisible beam of light from the emitter unit to the
transponder unit across from the pathway of the door. The door opener will not operate until the safety
sensor is programmed to the power head and it is 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 station
up/down button. However, the door may be closed by continuously holding your finger on the wall sta-
tion up/down button (constant pressure) until the door travels to a fully closed position.
Note: If two or more door openers are installed in
the same garage, the safety sensor transponder for
the second and/or third doors must be set to a dif-
ferent code to prevent interference with the first
transponder. The code is set by a jumper, located
under the battery, closest to the center of the com-
partment, as illustrated. The code jumper has three
positions (A-B-C), selected by a moveable jumper,
and has been randomly set at the factory to one of
these positions. If the factory random selection of
the jumper position has resulted in a different code for each transponder, no further changes are necessary. If
not, note the position of the jumper (A, B or C) on the first door transponder and set the second door trans-
ponder jumper to one of the other two positions. A third door will use the remaining un-used position. Temporar-
ily remove the batteries from all but the door being worked on and then replace when all jumpers have been set.
The jumper has no polarity and can be applied to the pins in either direction. For more than three doors, call for
technical assistance.
At this point you will be able to activate the opener. It will open, but will not
close the door. Before unit will close door the beam sensors must be aligned
and programmed.
First, the “Align-Normal” switch on the EMITTER (under the protective
cover) must be set to Align. (See illustration). This should cause the
adjacent RED LED indicator light to turn on. Check to see that the
EMITTER is pointed toward the TRANSPONDER and that the hex nut
holding the EMITTER in place is tight enough that the unit will not
move.
Loosen the hex nut on the TRANSPONDER just
enough that you can rotate it up and down and
side to side. Rotating the TRANSPONDER will
cause the GREEN LED on the TRANSPONDER
to blink when aligned. Rotate TRANSPONDER up
and down and side to side to determine best
alignment. We recommend wide rotations to help
determine the closest center point of alignment.
Tighten hex nut on TRANSPONDER and push
and hold PROGRAM SWITCH button on the
opener until the light bulb and PROGRAM
STATUS LED on the opener blinks showing pro-
gramming and alignment are completed. Reset
“Align-Normal” switch on the EMITTER to Normal
and snap cover shut.
Now, using the wall control up/down button, acti-
vate the opener and check that it will operate
through full open and close cycles.
