Test Safety Beam Sensor System
To test the safety beam sensor system, open the door to the
fully open position.
1) Place an obstacle (such as the opener carton) to break
the safety infrared beam
2) Press the push button to close the door
3) The door should not move more than an inch, and the
opener light will flash. If this does not happen:
- Ensure the safety beam sensors are aligned properly
(Refer to “Install Safety Beam Sensor System”)
- Ensure the obstacle is breaking the beam by checking
the receiving sensor green LED is off
- If everything fails, call for a trained door systems
technician
Without a properly installed safety reversing
sensor, persons (particularly small children)
could be seriously injured or killed by a closing
garage door.
Test Safety Reversal System
With the door fully open, place a 1-1/2” (3.8cm) board (or a
2X4 laid flat) on the floor, centered under the garage door.
Close the door by pressing the push button..
After making contact with the board, door must stop on
striking the obstruction, then reverse to the fully open
position.
If the door fails to reverse:
- If the door stops on the obstruction, re-adjust the down
travel limit as it is not traveling far enough in the down
direction.
- Repeat the test until the door reverses on striking the
obstruction.
