SETTING SAFETY OBSTRUCTION FORCE

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 O/S/C button (
Fig. 22
)
.
2.
Place a length of timber approximately 40mm high on the
floor directly under the door (
Fig. 23
).
3.
Press the Yellow O/S/C 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 Yellow O/S/C 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. 22
)
2.
While holding down the Force Margin button, press the
Open button (
Fig. 22
). Each press increases the force margin.
The Open Limit LED will illuminate each time the Open
button is pressed. Each press increases the force margin. Test
the force as per step 8.1 and 8.2. If the Open Limit LED
flashes continuously when the open button is being pressed,
this indicates that the maximum force pressure setting has being
reached.
17.4 TO DECREASE FORCE PRESSURE
1.
Press and hold the Force Margin Set button (
Fig. 22
).
2.
While holding down the Force Margin button, press the
Close button (
Fig. 22
). Each press decreases the force margin.
The Close Limit LED will illuminate each time the Close
button is pressed. Test the force as per step 8.1 and 8.2. If the
Close Limit LED flashes continuously when the Open button is
being pressed, this indicates that the maximum force
pressure setting has being reached.
17.5 TO RECALL FACTORY SET FORCE
1.
While holding down the Force Margin Set button (
Fig. 22
)
press the SET button (
Fig. 22
) for two seconds.
2.
Release both buttons. The default setting should now be
recalled.
