Install Protector System™(Optional) – (See accessories)
After opener has been installed and adjusted, The Protector System™ accessory can be installed. Instructions are
included with this optional device.
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.

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, it is not
traveling far enough in the down direction. Move Close
Limit closer to door
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, adjust Limit 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.
