12Setting 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.

13 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.

14Install 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.
