7. SETTING OPEN AND CLOSE SAFETY
OBSTRUCTION FORCE
The Safety Obstruction Force is calculated automatically and
set in memory on the Easylifter. This applies to both the Open
Force and Close Force.
Warning: When step 7.1 is initiated the garage door will do a
full open and close cycle automatically. Please keep doorway
clear to avoid any personal injury or damage to property.
7.1 TO INITIALISE OBSTRUCTION FORCE
1. Press and hold the Close button (Fig. 20) 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 (Fig. 20) for two seconds, the door
should start opening. When the door reaches the fully open
position it will pause momentarily then start to close. The door
has to do a complete open and close cycle without
interruptions for the safety obstruction parameters to be
calculated and set automatically.
A default safety force margin is preset in the factory. Under
normal operating conditions this default margin should not be
changed. If you are not satisfied with this setting you can adjust
it as per the procedure below.
IMPORTANT NOTE:
Whenever the limit switches or cams are adjusted the safety
obstruction force has to be re-initialised because the door’s
travel distance may have changed. To re-initialise the door
follow STEP 7.1 above.
7.2 TO INCREASE FORCE PRESSURE
1. Press and hold the Force Margin Set button (Fig. 20).
2. While holding Force Margin Set press the green Open
button. 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 continuously when the open
button is pressed, this indicates that the maximum force
pressure setting has been reached.
7.3 TO DECREASE FORCE PRESSURE
1. Press and hold the Force Margin Set button (Fig. 20).
2. While holding down button press the red Close button. The
red LED will illuminate each time the Close button is pressed,
to indicate that the force pressure is being reduced. If the red
LED flashes continuously when the close button is pressed, this
indicates that the minimum force pressure setting has been
reached.
7.4 TO RECALL FACTORY SET FORCE
1. While holding the Force Margin Set button press the RESET
button for two seconds.
2. Release both buttons. The default setting should now
be recalled

strike the object and start to re-open.
TESTING OPEN CYCLE
1. Close the door by pressing the Yellow O/S/C button. (Fig. 20).

grab the bottom rail of the door firmly, the door should stop.
If the door does not reverse readily when closing, or stop when
opening, the force may be excessive and need adjusting, refer to
STEP 7.1, 7.2, 7.3 and 7.4.
IMPORTANT WARNING: If the door is closing and is unable to
re-open when obstructed discontinue use. Do not use a door with
faulty obstruction sensing. Repair fault and re-test before using.
