Step 4 TESTING THE SAFETY SYSTEM
The opener automatically adjusts the force required to reverse when closing or to stop when opening when an
obstruction is encountered. The operation of the Safety System must be tested whenever there has been any
change in settings or any adjustment to the door, and monthly during the operational life of the opener. To test the
safety system the following procedure should be used.
Door Closing Test
•
Ensure that the door is open.
•
Place a 40mm obstacle laid flat on the floor under the garage door.
•
Operate the door in the down direction, the door must reverse on hitting the obstruction.
•
If the door fails to reverse, remove the obstacle and reset the door travel limits (ensure the bottom limit is set
firmly at the floor). Operate the opener for five cycles, place the 40mm obstacle on the floor under the garage
door and then retest.
Note: If the door fails again, there may be a problem with your garage door and you will need to call for service.
•
Remove the obstacle and run the opener through a complete travel cycle. Test overload sensitivity by using
your hand to resist the closing motion of the door (eg, by holding the bottom rail of the door), the door should
reverse at the half open position.
Door Opening Test
•
Ensure that the door is closed.
•
Operate the opener to open the door.
•
While the door is opening (approximately 1 metre off the floor) hold the bottom edge of the door with your hand.
When a reasonable downward force (100 Newtons/10kg) is exerted, the door should halt.
•
This will cause the LED’s to start flashing to indicate an error.
•
Clear the collision error by pressing the operate button or a coded remote control transmiter, the LED’s will stop
flashing.
•
If the door fails to halt, operate the opener for five cycles and then re-test. If the door fails again you will need to
call for service.
Note: Check to make sure the door opens and closes properly.
Note: The use of safety infra red beams (Part No 062153) is recommended with all installations of automatic garage
door openers.
The safety system is designed to prevent entrapment or serious injury. It relies upon
physical contact with objects in the path of the door. The safety system alone may
not prevent cosmetic damage to motor vehicles or property.
