Step 22: 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 23.
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
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 23: 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.
