TEST THE SAFETY REVERSE SYSTEM
The safety reverse system test is important. Garage door must reverse on contact with a 40 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.
Procedure: With door opened place a 40 mm obstacle (1)
laid flat on the floor under the garage door. Operate the
door in the down direction. The door must reverse off the
obstacle. If the door stops on the obstacle, remove obstacle
and repeat Program the Limits and Force Steps, then
repeat safety reverse test.
When the door reverses off the 40 mm obstacle, remove
the obstacle and run the opener through a complete travel
cycle. Door must not reverse in closed position. If it does,
repeat Program the Limits and Force then repeat safety
reverse test.
