Safety Reverse Test
It is important that a safety reverse system test is carried out. The garage door must reverse on
contact with a 40mm object placed flat on the floor. Incorrect force adjustment can result in serious
injury.
Operate the door to the closed position with the
object in place under the door. The door must reverse
upon contact with the object. If the door stops, but
does not reverse, adjust the safety reversal force, see
page 10.
Always repeat safety reverse test after adjusting
force.
Note:
Open and close the door 4 times to ensure the limits are correctly set. After checking the position, it
is important to now test the safety reverse feature, see below.
