Test the Safety Reversal System
TEST
• With the door fully open, place a 40 mm high object laid
flat on the floor, centred under the garage door.
• Operate the door in the down direction. The door must
reverse on striking the obstacle.
ADJUST
• If the door stops on the obstacle, it is not travelling far
enough in the down direction. Complete Adjustment
Step 1, Programming the Limits and Forces to increase
travel distance in the down direction.
NOTE: Make sure the limit adjustments do not
force the door arm beyond a vertical position.
Refer Figure 3, page 14.
• Repeat the test.
• When the door reverses on the 40 mm high object laid
flat, remove the obstacle and run the opener through 3
or 4 complete travel cycles to test adjustment.
• If the opener continues to fail the Safety Reverse Test,
call for a qualified door technician.

• Each adjustment of door arm length, limits, or force
controls.
• Any repair to or adjustment of the garage door
(including springs and hardware).
• Any repair or changes to the garage floor.
• Any repair or adjustment of the opener.
