Safety beam sensors must be installed and aligned correctly for the
garage door opener to operate properly.
1. Both safety sensors should be facing each other without any
obstruction.
2. 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. Further alignment is necessary if any LEDs are not
glowing steadily.
Red LED is the transmitting sensor, Blue LED is the receiving sensor.
If the Red LED is not glowing, please check the followings:
1. Make sure the garage door opener is plugged into AC power.
2. Make sure the sensor wires are not shorted / broken.
3. Ensure the sensor has been wired correctly. White non-marked
wires are twisted together and insert to one safety sensor terminal.
White marked wires are twisted together and insert to another safety
sensor terminal.
If the Blue LED is not glowing, please check the followings:
1. Make sure the sensors are aligned. Reposition the sensor bracket until
the Blue LED is glowing steadily.
2. Make sure the sensor wires are not shorted / broken.
