6. FIXING OF DOOR CURTAIN TO
DRUM WHEEL
The door curtain has to be secured to the drum wheel with
suitable fasteners.
1. With the door in the fully closed position mark the
curtain (Fig. 9) on both ends of the door.
2. Open door slightly to have access to the marked
positions. Secure the curtain to drum wheel using
self drilling screws (two on each end). The screws
should be at least 90 degrees apart (Fig. 9).
7. SETTING LIMIT SWITCHES
IMPORTANT NOTE: The O / S / C button
and Transmitters will not function until the
Limits are adjusted and Step 8.1 is completed.
The Limit Cams, Limit Fine Adjustment Screws and Door
Drive buttons are colour coded to make the setting of the
limits as user friendly as possible.
The GREEN colours for OPEN LIMIT SETTING.
The RED colours for CLOSE LIMIT SETTING.
7.1 SETTING LIMITS FOR RIGHT
HAND INSTALLATION
1. With the Drive Unit in manual mode (Fig. 13)
move the door up by hand to the desired open position.
2. Remove the Limits Cover (Fig. 10). Rotate
by hand in a anticlockwise direction the green
limit cam (Fig. 11) until the cam clicks the
open limit switch.
3. Move the door down by hand to the desired closed
position.
4. Rotate by hand in a clockwise direction the red limit
cam (Fig. 12) until the cam clicks the close limit
switch.
5. Connect power lead from the Drive Unit into,
a general purpose power outlet installed by a licensed
electrical contractor. Turn the Power On.
6. Re-engage the drive gear to door by pulling down on
the string and then releasing slowly (Fig. 13).
OPEN LIMIT ADJUSTMENT
Press in and hold the Green Open button (Fig 11) The
door should start opening. Release the Green Open but-
ton when the door reaches the desired open position. If
the Green LED (Fig. 11) is illuminated and the desired
limit position has been reached then the limit adjust-
ment is complete. If the Green LED is illuminated but
you are not happy with the door open position, the
Green Fine Adjustment Screw (Fig. 11) can be adjusted
to fine tune the open position. Adjust the screw anti-
clockwise to open the door more. To open the door less
adjust the screw clockwise. Each complete revolution
of the adjustment screw is equal to approximately 10
mm of door travel.
