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.
Final Adjustments and Testing
Testing the Safety Reverse System
The Safety Reverse System prevents the door from closing
when an obstruction is present.
1.
Open the door by using the “UP” button or Wall Panel.
2.
Place a 1-1/2” (3.8cm) thick solid object (or 2x4 laid flat)
on floor under the center of garage door.
3.
Keeping the door in sight, use the “DOWN” button to close
the door.
4.
The door MUST REVERSE and beeps within 1.5 seconds
upon striking the object , and stop at the fully opened
position.
5. The Safety Reverse System works properly and the
opener is ready to use.
If the door just stops on the object, adjust 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.
