Step 23: Alignment of the Wired Infrared Safety Sensors
Use the following instructions if your opener is equipped with Wired Infrared Safety Sensors.
Otherwise proceed to step 24.
IMPORTANT: This infrared beam sensor sends an invisible beam of light from the sending unit to the
receiver unit across from the pathway of the door. The door opener will not operate until the safety sen-
sor is connected to the power head and properly aligned. If the invisible beam of light is obstructed, 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 station
up/down button (constant pressure) until the door travels to a fully closed position.
At this point you will be able to activate the opener; it
will open, but will not close the door unless the beam
is aligned. The beam sensors must be aligned by
moving the sending and receiving units in or out (see
Figure 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 dif-
ficulty aligning beams, check that both brackets are
mounted at the same height (see Step 9) and remount
if necessary. Additional minor adjustments can be
made by lightly bending the mounting brackets (see
Figure 2).
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 ex-
tra wire.
Now, using the wall station up/down button, activate
the opener and check that it will operate through full
open and close cycles.
Step 24: Transmitter Security Code Change and Programming
Note:
The following steps describe the process to change the Transmitter security code and to program the
Transmitter to the opener.
IMPORTANT: You MUST change the Transmitter security code prior to programming the device to the power
head unit.
WARNING: During programming the garage door may operate. Keep people and objects clear of the
moving door to prevent door damage or possible personal injury.
Changing the Transmitter Code
1.
Press and hold the Transmitter’s large button for approximately 10
seconds until Transmitter’s LED begins to blink rapidly.
Release but-
ton (LED will turn off).
2.
Press and hold the Transmitter’s large button again (LED will light) for
approximately 5 seconds until the Transmitter’s LED begins to blink
rapidly. Release button.
3.
LED will blink on and off three times indicating a successful security
code change.
