Step 15.6 - Set the Open Limit Position
Press and hold the PLUS (+) button (Fig. 26) until the
door reaches the desired open limit position.
With a small screwdriver turn the green open limit
adjust screw (Fig. 27) clockwise until the green OPEN
LIMIT LED is illuminates.
Step 15.7 - Fine Tuning the Open Limit
Position
Hold the MINUS (-) button to close the door
approximately half a metre.
Hold the PLUS (+) button to fully open the door.
Check that the open limit position is correct and that
the OPEN LIMIT LED is illuminated. If an adjustment
is necessary turn the open limit adjust screw (Fig. 27)
as required, and then repeat Steps 15.7(a) and (b).
Turning the open limit screw towards (+) allows the door
to drive more in the open direction, while turning towards
(-) allows the door to drive less in the open direction.
Otherwise, read the
WARNING
below and proceed
to Step 15.8.
IMPORTANT WARNING:
The door will automatically
close, open and close again
once Step 15.8 is
performed
. Ensure that no persons or objects are in the
door’s path.
Step 15.8 - Storing the Open Limits & Auto-
Calculating the Safety Obstruction Force
Press the LIMIT SET button (Fig. 26) to store the open
limit position.
The door will now automatically close to its limit
position then fully open to calculate the safety
obstruction forces.
Be aware of the above
warning.
The safety obstruction force is calculated automatically
and set in the memory of the opener. This applies to both
the open and close force.
The opener can now be operated via the OPERATE
button.
IMPORTANT NOTE:
Whenever the limit adjustment
screws are altered the safety obstruction force has
to be re-initialised as travel distances may have altered.
To reset the limits and force margin hold the LIMIT
SET button for approximately six seconds until the red
CLOSE LIMIT LED starts to fl ash, then follow steps 15.3
onwards.
