Adjusting Safety Obstruction Force
The Safety Obstruction Force is calculated automatically
during setup. Adjusting this is normally only necessitated
by environmental conditions such as windy or dusty areas,
and areas with extreme temperature changes.
WARNING! Photo electric beams must be installed
if the closing force at the bottom edge of the door
exceeds 400N (40kg) force.
Step 16.1 - To Increase Force Pressure
Hold down FORCE MARGIN SET button (Fig. 29)
While holding the FORCE MARGIN SET button,
press the PLUS (+) button. Each press increases the
force margin (Fig. 29).
The OPEN LIMIT LED will fl ash each time the PLUS
(+) button is pressed to indicate a force increase
If the OPEN LIMIT LED is on continuously when
pressing the PLUS (+) button, this indicates that the
maximum setting has been reached.
Test the force again as per Steps 15.1 and 15.2
Step 16.2 - To Decrease Force Pressure
Hold down FORCE MARGIN SET button (Fig. 29)
While holding the FORCE MARGIN SET button,
press the MINUS (-) button. Each press decreases
the force margin (Fig. 29).
The CLOSE LIMIT LED will fl ash each time the MINUS
(-) button is pressed to indicate a force decrease.
If the CLOSE LIMIT LED is on continuously when
pressing the MINUS (-) button this indicates that the
maximum setting has been reached.
Test the force again as per Steps 15.1 and 15.2
Step 16.3 - To Recall Factory Set Force
While holding down the FORCE MARGIN SET
button, press the SET button for two (2) seconds.
(Fig. 30)
Release both buttons. The default setting should
now be recalled.
Step 16.4 - To Recalculate Force Margins
Press and hold the SET Button for two (2) seconds,
the beeper will sound once (Fig. 31).
The door will start to move and re-calculate force
margins. The door can move between the open and
close limit positions up to four (4) times (depending
on the position of the door and the power up
condition).
A single beep will be heard once the process is
complete.
Test the force again as per Steps 15.1 and 15.2.
