ADJUSTMENT STEP 3
Test the Safety Reversal System
TEST
• With the door fully open, place a 40mm board 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
Steps 1 and 2 Programming the Limits and Forces.
NOTE: On a sectional door, make sure limit
adjustments do not force the door arm beyond a
vertical position. Refer Figure 3, page 15.
• Repeat the test.
• When the door reverses on the 40mm board 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.
IMPORTANT SAFETY CHECK:
Test the Safety Reverse System after:
• 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.
• Safety reversal system MUST be tested every month.
• After ANY adjustments are made, the safety reversal system
MUST be tested. Door MUST reverse on contact with 40mm
obstacle on the floor.
