The Protector System
TM
must be used for all
installations where the closing force as
measured on the bottom of the door is over
400N (40kgf).
SETTING THE FORCE SENSITIVITY
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
TM
must
be installed (refer section 21). The force setting regulates
the amount of power required to open and close the door.
This procedure requires the door to be engaged (see
section 14) and run through one full cycle of operation.
Step 1:
Start with the door in the fully open position and the
green control panel cover should be removed (see fig 1
section 22). Press the red
“learn”
button twice on the con-
trol panel to enter into the force learn mode. The amber
LED marked
open
on the control panel will flash quickly.
Step 2:
Press the green
operate
button on the control
panel. The door will travel to the DOWN limit. Press the
operate button again, the door will travel to the UP limit. The
amber LED marked
open
on the control panel will stop
flashing when the force has been learnt.

Procedure:
Place a 40mm obstacle (1) laid flat on the floor under the garage door. Operate the door in the
down
direc-
tion. The door
must
reverse on the obstacle. If the door
stops
on the obstacle, it is not travelling far enough in the
down
direction. Remove the lamp cover to locate the travel limit adjustment screws. Increase the
down
limit by turning
down
limit adjustment screw clockwise (1 turn = approximatly 250mm travel).
Repeat 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, adjust Limits and Force and repeat safety reverse test.
Repeat test once a month and adjust as needed
.

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 opener may result in serious personal injury
from a closing garage door.
