8. SETTING OF OPEN AND CLOSE
SAFETY OBSTRUCTION FORCE
The Safety Obstruction Force is calculated automatically and
set in memory on the Automatic Opener. This applies to both
the Open Force and Close Force.
Warning:
When step 8.1 is initiated the Garage Door will
do a full open and close cycle automatically. Please keep
door way clear to avoid any personal injury or damage to
property.
8.1 TO INITIALISE OBSTRUCTION FORCE
1. Press and hold down the close button 8 (FIG. 16), to move
the door to the fully closed position. Check that the RED
LED is steady ON, to confirm the door is set on the closed
limit position.
2. Press the Reset button 5 (FIG. 16) for two seconds, the
door should start opening. As soon as the door reach‟s the
fully open position it will pause momentarily then start to
close.
The door has to do a full open and close cycle with no
interruptions for the safety obstruction parameters to be
calculated and set automatically.
A default safety force pressure margin is preset in the factory.
Under normal operating conditions this default margin should
not be changed. If you are unhappy with the pressure you can
change it as below.
8.2 TO INCREASE FORCE PRESSURE
1. Press and hold the Force Margin Set button 1 (Fig. 16).
2. While holding down button 1 press the green Open
button 3. The green LED will illuminate each time the
green open button is pressed to indicate that the force
pressure is being increased. If the green LED flashes con-
tinuously when the open button is being pressed, this
indicates that the maximum force pressure setting has been
reached.
8.3 TO DECREASE FORCE PRESSURE
1. Press and hold the Force Margin Set button 1 (Fig. 16).
2. While holding down button 1 press the red Close button 8.
The red LED will illuminate each time the red Close.
button is pressed, to indicate that the force pressure is
being reduced. When the red LED flashes continuously
when the red close button is being pressed, this indicates
that the minimum force pressure setting has been reached.
8.4 TO RECALL FACTORY SET FORCE MARGIN
1. While holding down the Force Margin Set button 1 press
the RESET button 5 for two seconds.
2. Release both buttons. The default setting should now be
recalled.
IMPORTANT NOTE:
Whenever the Limit Switches or Cams are
adjusted the safety obstruction force has to be
re-initialised because the door travel distance
may have changed. To re-initialise please follow
STEP 8.1 above.
