TEST THE SAFETY REVERSE SYSTEM
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 obstacle. If the door stops on the obstacle, remove obstacle and repeat Setting the Limits and
Force Steps, then repeat safety reverse test.
When the door reverses on the 40mm obstacle, remove the obstacle 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 then repeat safety reverse test.

Connecting the Protector System
Locate the terminals on the back of the unit. Strip all
wires back about 10mm then twist the two white wires
and the two white/black wires together. Trim the twisted
wires to approximately 6mm. Use a small screwdriver or
pen to hold down the spring terminals, insert the
white/black wires into the grey terminal (4), then
terminate the white (only) wires into the white terminal
(3).
INSTALL THE PROTECTOR SYSTEM™
(See accessories)
Install this accessory for all installations on tilt doors, 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.
SAFETY FIRST!
Whilst Chamberlain have engineered safety features into your
garage door opener, we urge you to consider fitting IR Beams
to your new garage door opener. In many countries these
devices are compulsory to prevent serious injury or property
damage. For your own peace of mind and the safety of others
please install this inexpensive safety device.

STANDARD INSTALLATION COMPLETE
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.
