Final Adjustments and Testing
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 and 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 Reversal Test MUST be performed to ensure
the door reverses on contact with a 1-1/2 inch (3.8 cm) thick (2x4 laid flat) object.
- The Photo Eye Safety System MUST be properly aligned, and tested regularly.
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 Door Control Console.
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 Remote Control to close the door.
4. The door MUST REVERSE upon striking the object within 1.5 seconds, and stop at the full opened position.
5. The courtesy light will start flashing for 30 seconds upon triggering the Safety Reverse System.
If the door fails to reverse upon contact with obstruction, adjust the Opener as follows:
The close travel maybe inadequate, Increase Close travel limit by 1/4 turn (See Limit Adjustment on page 17).
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 18) 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 Door Control Console.
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 green indicator light on the emitter eye should flash.
5. The red indicator light on the sensor eye should be dimmed.
6. Keep the door in sight and use the Push Button or Remote Control to try to close the door.
7. The door should NOT move more than 1" (2.5cm) and tand the courtesy light should flash for 30 seconds.
