Align the safety reversing sensors
The door will not close if the sensors have not been installed and aligned correctly.
NOTE: After finishing the installation, do not operate this opener at this time.
See Set Door Profile and Program the Travel for setting the door drum size and travel limits. Both of these processes are critical to safe
and proper operation. Failure to follow these instructions can result in opener and door damage!
The LEDs in both sensors must be glowing steady, which indicates they are powered and aligned correctly. The sending sensor (with an amber
LED) transmits an invisible light beam to the receiving sensor (with a green LED). If an obstruction breaks the light beam while the door is
closing, the door will stop and reverse to the full open position. If the door is already open, it will not close.
TO ALIGN SENSORS:
The sensors can be aligned by loosening the wing nuts, aligning the sensors, and tightening the wing nuts.
If the LEDs are not glowing steadily:
Receiving Sensor
(will have sticker on back)
Green LED
Sending Sensor
Amber LED
If the receiving sensor is in direct sunlight,
switch it with sending sensor so it is on the
opposite side of the door.
(invisible light beam)
Installation (continued)
• Check that both sensors are installed inside the garage, one on either side of the door.
• Check that sensors are facing each other with the lenses aligned and the receiving sensor light does not receive direct sunlight.
• Check that sensors have the same measurement, no higher than 6” above the floor.
Amber LED is not lit:
• Check there is power to the garage door opener.
• Check the sensor wire is not shorted/broken.
• Check the sensor has been wired correctly: white wires to white terminal and white/black wires to grey terminal.
Green LED is not lit:
• Check that the sensor wire is not shorted/broken.
• Check that the sensors are aligned.
