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 Push Button or Transmitter
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 Push Button or
Transmitter to close the door.
4.
The door MUST REVERSE upon striking the object within
1.5 seconds, and stop at the fully opened position.
5.
The courtesy light will start flashing for 30 seconds upon
triggering the Safety Reverse System.
If the door just stops on the object, adjust the Opener as
follows:
The close travel maybe inadequate, Increase Close travel limit
by 1/4 turn (See
Limit Adjustment
on page 16)
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 door still does not reverse on the object, decrease the
Close Force (see
Force Adjustment
on page 17) and repeat
the test.
If the Opener still fails the Safety reverse Test, call a qualified
technician for door adjustment.
Testing the Photo Eye Safety System
1.
Open the door by using the Push Button or Transmitter
2.
Make sure both Photo Eyes steadily emit the green and
red indicator lights. (If not, check alignment)
3.
Place an object under the door about 8” (20cm) high by
12” (30cm) wide (the Opener carton can be used),
4. The red indicator light on the sensor eye should be
dimmed.
5. Keep the door in sight and use the Push Button or
Transmitter to try to close the door.
6.
The door should NOT move more than 1” (2.5cm) and the
courtesy light should flash for 30 seconds.
