SAFETY OBSTRUCTION TEST
Please take care when testing the Safety Obstruction
Force. Excessive force may cause SERIOUS PERSON-
AL 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.
17.5 TO RECALL FACTORY SET FORCE
1. While holding down the Force Margin Set button, press
the SET button (Fig. 22) for two seconds.
2. Release both buttons. The default setting should now
be recalled.
