Setting the Force
The force, as measured on the closing edge of the door,
should not exceed 400N (40kg). If the closing force is
measured to more than 400N, the Protector System must
be installed See step 29.
The force setting regulates the amount of power required
to open and close the door.
1. Locate the orange button (2).
2. Push the orange button (2) twice to enter unit into Force
Adjustment Mode. The LED (3) (indicator light) will flash
quickly.
3. Push the programmed remote control (4) or push bar on
the door control that was shipped with your opener. The
door will travel to the DOWN (close) position. Push the
remote control (4) again, the door will travel to the UP
(open) position.
The LED (3) (indicator light) will stop flashing when the force
has been learned.
The door must travel through a complete cycle, UP and
DOWN, in order for the force to be set properly. If the unit
cannot open and close your door fully, inspect your door to
insure that it is balanced properly and is not sticking or
binding.

Test the Safety Reverse System
The safety reverse system test is important. Garage door
must reverse on contact with a 40mm obstacle laid flat
on the floor. Failure to properly adjust opener may result
in serious personal injury from a closing garage door.
Repeat test once a month and adjust as needed.
Procedure: Place a 40mm obstacle (1) laid flat on the floor
under the garage door. Operate the door in the down
direction. The door must reverse on the obstruction. If the
door stops on the obstruction, remove obstruction and repeat
Setting the Limits step 26. Repeat test.
When the door reverses on the 40mm obstacle, remove the
obstruction and run the opener through a complete travel
cycle. Door must not reverse in closed position. If it does,
repeat Setting the Limits and Force steps 26 and 27 and
repeat safety reverse test.
Place 20kg at the center of the door and ensure that the door
will not move up more than 500mm.

Install the Protector System ™
(See accessories)
Install this accessory for all installations on Canopy doors,
One-Piece Door with Horizontal and Vertical Track , doors
over 2.5m and when the closing force as measured on the
bottom of the door is over 400N (40kg).
After opener has been installed and adjusted, The Protector
System™ accessory can be installed. Instructions are included
with this accessory.
The Protector System™ provides an additional measure of
safety against a small child being caught under a garage
door. It uses an invisible beam which, when broken by an
obstruction, causes a closing door to open and prevents an open
door from closing and is strongly recommended for homeowners
with young children.
Note: The opener will automatically detect the protector system
when it is installed. The opener will not close unless the sensors
are aligned.
