Step 21: 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 22.
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
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
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
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 release the PROGRAM Switch button located on the garage door power head unit once. The red PROGRAM STATUS light on the motor power head unit and overhead lamp blinks showing programming and alignment are completed. Reset
