Step 17. Safety obstruction test
Please take care when testing the Safety Obstruction
Force. Excessive force may cause SERIOUS PERSONAL
INJURY and/or PROPERTY DAMAGE can result from
failure to follow this warning.
17.1. Testing close cycle
1. Open the door by pressing the Yellow Operate
button
(Fig. 25).
2. Place a length of timber approximately 50mm high
on the floor directly under the door
(Fig. 25a)
.
3. Press the Operate button to close door. The door
should strike the object and start to re-open.
17.2. Testing open cycle
1. Close the door by pressing the Operate button.
2. Press again to open the door. When the door
reaches half the opening distance, 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 17.4.
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.
Adjusting safety obstruction force
The Safety Obstruction Force is calculated
automatically and set in memory on the SecuraLift®
opener. It is usually not necessary to adjust the Safety
Obstruction Force. The only time the force may need
to be increased is due to environmental conditions, for
example, windy or dusty areas, and areas with extreme
temperature changes.
17.3. To increase force pressure
1. Press and hold the Force Margin Set button
(Fig. 25)
2. While holding down the Force Margin button, press
the Plus (+) button. Each press increases the force
margin. The Open Limit LED will flash each time
the Plus button is pressed to indicate an increase in
force. Test the force again as per step 17.1 and 17.2
above. If the Open Limit LED flashes continuously
when the Plus button is being pressed, this indicates
that the maximum force pressure setting has been
reached.

17.4. To decrease force pressure
1. Press and hold the Force Margin Set button
(Fig. 25).
2. While holding down the Force Margin
button, press the Minus (-) button. Each press
decreases the force margin. The Close Limit
LED will flash each time the Minus button is
pressed. Test the force again as per step 17.1
and 17.2 above. If the Close Limit LED flashes
continuously when the Minus button is being
pressed, this indicates that the maximum force
pressure setting has been reached.

button, press the SET button
(Fig. 22)
for
two seconds.
