WARNING
To prevent SERIOUS INJURY or DEATH from a closing garage door:
- The Safety Reversal Test MUST be conducted ONCE A MONTH.
- NO ONE should cross the path of moving door during operation and/or testing.
- If either Force or Travel limit adjustment is made, the other adjustment may also needed.
- After ANY adjustments to the door system, the Safety Reverse Test MUST be performed to ensure the
door reverses on contact with a 1-1/2” thick (2x4 laid flat) object.
- The Photo Eye Safety System MUST be properly aligned, and tested regularly.
Testing the Safety Reverse System

when an obstruction is present.

flat)
on floor un
der the center of garage door
.
3.
Keeping the door in sight, use the Push Button to
close
the door.

within 1.5 seconds
upon
striking the object , and stop at the fully open
positio

If the door fails to reverse upon conta

the Opener as follows:
The close travel maybe inadequate, slightly increase the DOWN
limit. (See Travel Limit Adjustment on page 17-19)
Conduct the test again. If the door reverses on contact, remove
the object and run at least 3 COMPLETE travel cycles to ensure
proper adjustment.
If the Opener still fails the Safety Reverse Test, call a qualified
technician for door adjustment.
