Setting the Force
The force, as measured on the closing edge of the door,
should not exceed 400N (40kgf). If the closing force is
measured to more than 400N, the Protector System must
be installed. See section 14.
The force setting regulates the amount of power required to
open and close the door.
1. Press the purple button (1) twice to enter opener into Force
Adjustment Mode. The indicator light (2) will flash quickly.
2. Press the green start button (4) on the bottom of the
opener. The door will travel to the DOWN limit. Press the
green start button (4) again, the door will travel to the
UP limit. Press the green start button (4) again to
complete the travel cycle. The indicator light (2) 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 opener
cannot open and close your door fully, inspect your door to
insure that it is balanced properly and is not sticking or
binding.

Testing the Safety Reverse System
The safety reverse system test is important. The garage
door must reverse on contact with a 40mm obstacle laid
flat on the floor. Failure to properly adjust the opener may
result in serious personal injury from a closing 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 limit and force setting, sections
11 & 12, pages 6 & 7. Repeat test.

Install the Protector System
((
Safety Beams)
Install this accessory for all installations where the
closing force as measured on the bottom of the door is
over 400N (40kgf).
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 and operating for 5 minutes
without the beams being obstructed. The opener will not
close unless the sensors are aligned.
