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. 13) 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. 13).
SETTING DOOR TRAVEL LIMIT POSITIONS
IMPORTANT NOTE: The O/S/C button will not function until the open and close limits positions are set and Step 7.1 is completed.
The Limit Cams, Limit Fine Adjustment Screws and Door Inch Open and Close 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.
SETTING LIMITS FOR RIGHT HAND INSTALLATION
1. With the drive unit in manual mode (Fig. 14) move the door up by hand to the desired open position.
2. Remove the light diffuser (Fig. 14). Rotate the green limit cam by hand in an anticlockwise direction (Fig. 15) until the cam clicks the open limit switch.
3. Move the door down by hand to the desired closed position.
4. Rotate the red limit cam by hand in a clockwise direction (Fig. 16) until the cam clicks the close limit switch.
5. Connect the power lead from the drive unit into, a general purpose power outlet installed by a licensed electrical contractor. Make sure that the power lead is safely fastened away from any moving parts.Turn the power on.
6. Re-engage the drive gear by pulling down on the string and then releasing slowly (Fig. 14).
OPEN LIMIT ADJUSTMENT
Press and hold the green Open button (Fig. 15) The door should start opening. Release the green Open button when the door reaches the desired open position. If the green LED (Fig. 15) is illuminated and the desired limit position has been reached then the limit adjustment is complete. If the green LED is illuminated but you are not happy with the door’s open position, the green Fine Adjustment Screw (Fig. 15) can be adjusted to fine tune the open position. Turn the screw anticlockwise to open the door more. To open the door less turn the screw clockwise. Each complete revolution of the adjustment screw is equal to approximately 10mm of door travel.
