If there are no safety devices fitted then this
button must be held while the third stage of the
calibration process is carried out, otherwise it
can be released once the door starts to open.
The door should automatically open fully, wait
and then close fully. During this process it will
beep repeatedly and the Operator Light will
flash to warn that the Control Head is learning
the force profile of the door. Keep clear of the
door and wait for the third stage to end.

Once the third stage of the calibration process
is complete, the door will be closed and the
Operator Light will be lit with the beeper
sounding once every 5 seconds to indicate entry
into diagnostic mode. The door can now be
cycled using the
illuminated
Control Box button.
During the diagnostic runs, the door balance is
indicated by the brightness of the Operator
Light, the beeper will sound if a track irregularity
is detected, and the beeper will sound
repeatedly if the belt is slipping when the door is
at the fully open or closed position. See the
fault finding section on page 11 for further
details.
5:
To exit the diagnostic mode, press and release
the
PROGRAM
button, there will be two beeps
to indicate that the calibration is completed.
The Operator Light will fade out after 3 minutes.
TESTING THE DOOR OPERATION
Once calibration is complete the door should be
cycled normally a few times using the
illuminated
Control Box button to ensure
correct operation, the door must reverse when
it contacts a 1.5” high object (or a 2” by 4” board
laid flat) on the floor (Pic 23). See pages 11 and
12 to adjust the reversing decision height, the
soft start duration, the closing speed change
point and the obstruction tolerance if required.
Finally adjust the Manual Override Lever
tension now that the V-‐belt has bedded in.

There is an automatic close facility which can be
enabled by turning on the AUTOCLOSE switch.
The factory default close time is 15 seconds;

Light will flash for 5 seconds before the start of
the automatic close to warn of an impending
unattended door operation.
