INSTALLATION STEP 14

ALIGNING THE SAFETY REVERSING SENSORS

The door will not close if the sensors have not been installed and aligned
correctly.
When the light beam is obstructed or misaligned while the door is closing, the
door will reverse and the garage door opener lights will flash ten times. If the door
is already open, it will not close.
1. Check to make sure the LEDs in both sensors are glowing steadily. The
LEDs in both sensors will glow steadily if they are aligned and wired
correctly.
The sensors can be aligned by loosening the wing nuts, aligning the sensors, and
tightening the wing nuts.
IF THE AMBER LED ON THE SENDING SENSOR IS NOT GLOWING:
1. Make sure there is power to the garage door opener.
2. Make sure the sensor wire is not shorted/broken.
3. Make sure the sensor has been wired correctly: white wires to white
terminal and white/black wires to grey terminal.
IF THE GREEN LED ON THE RECEIVING SENSOR IS NOT GLOWING:
1. Make sure the sensor wire is not shorted/broken.
2. Make sure the sensors are aligned.
Figure 1
If the receiving sensor is in direct sunlight, switch
it with sending sensor so it is on the opposite
side of the door.
