Test the Safety Reverse System

The safety reverse system test is important. Garage door
must reverse on contact with a 50 mm obstacle laid flat
on the floor. Failure to properly adjust opener may result
in serious personal injury from a closing garage door. Repeat test
once a month and adjust as needed.
OBSTACLE TEST:
Place a 50 mm high obstacle (1) under the garage door on the floor.
Move door downwards. The door must reverse when it comes into contact
with the obstacle. If upon contact the door stops, the door does not move
down far enough. In this case repeat limit setting .
If the door reverses after contact with the 50 mm high obstacle, remove
obstacles and open and close the door completely once. The door should
not go back, if it reaches the door position „Closed". If it still reverses both
limits must be reprogrammed.
OPENING TEST: Apply 20 kg to the middle of the door.
The door should not open completely.
