Closing Force
a.
The door should be in the open position with power on.
b.
Set the closing force adjuster initially to the minimum position.
c.
Press the remote control transmitter (or whilst holding the light cover in place, press the operate button) to start
the door moving down. If the door reverses whilst closing (or does not move at all), increase the closing force
adjuster (turn the closing force adjuster clockwise) in small increments until the door closes properly
(Alternatively, for large doors you may set the closing force adjuster to the mid position and whilst the door is
moving down, decrease the closing force (slowly turning the closing adjuster anti clockwise) until the door
reverses.
Note: You may need to repeat steps a to c.
d.
Once you have completed step c., increase (turn clockwise) the closing force adjuster by 1/8th of a turn
e.
Operate the door to ensure that it closes without reversing.
Opening Force
f.
Set the opening force adjuster to the mid position.
g.
With the door in the closed position, operate the opener to open the door. Whilst the door is opening, decrease
the opening force (turn the opening force adjuster anti-clockwise) until the door halts (the Code Set and Limit Set
LED’s will flash to indicate a collision error).
h.
Clear the flashing LED’s by holding the light cover in place and press the operate button, the flashing LED’s will
stop flashing.
Note: - you may need to repeat steps g and h.
i.
Increase the opening force adjuster (turn the opening force adjuster clockwise) by 1/4 of a turn.
j.
Operate the door to ensure that it opens without halting.
Test
k.
Test the Safety Reversing System and make any adjustments as necessary.
l.
Refit the light cover and press the operate button to ensure the door opens and closes properly.
Permanently fix the label warning against entrapment and manual operation in a
prominent place or near any fixed controls.
After installation, ensure that the mechanism is properly adjusted and that the opener
reverses when the door contacts a 40mm high object placed on the floor under the
garage door.
Step 12: TESTING THE SAFETY SYSTEM
The operation of the Safety System must be tested whenever there has been any change in settings, or adjustment
to the door and tested 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, or stops on the obstruction, the down force will have to be decreased.
•
Remove the obstacle and run the opener through a complete travel cycle.
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 moderate downward force (100 Newton’s/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, the LED’s will stop flashing.
•
If the door fails to halt the up force will have to be decreased (see above).
Check to make sure the door opens and closes properly.
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.
