- Confirm availability of a suitable power supply (24VDC).
4.2. Mounting the Motor Unit
- Position the motor unit on a stable, level concrete base adjacent to the gate.
- Secure the motor unit using appropriate anchor bolts.
- Ensure the motor's output pinion aligns correctly with the gate's gear rack.
4.3. Installing Gear Racks
- Attach the gear racks along the length of the gate, ensuring they are level and parallel to the gate's movement.
- Maintain a small clearance (approximately 1-2mm) between the rack and the motor pinion to allow for gate movement.
- Connect the 39-inch rack sections securely.
4.4. Wiring and Electrical Connections
- Connect the motor unit to the control board according to the wiring diagram provided in the full technical manual.
- Install the photo cells at appropriate heights and positions to detect obstructions. Wire them to the control board.
- Connect the receiver unit to the control board.
- Ensure all electrical connections are secure and insulated.
4.5. Programming the Remote Controls

5.1. Opening/Closing the Gate
- Press the programmed button on your remote control once. The gate will begin to open or close.
- Pressing the button again during movement will typically stop the gate. A third press will reverse its direction.
- The photo cells will detect any obstruction in the gate's path and automatically stop or reverse the gate's movement for safety.
5.2. Manual Release
In case of power failure or malfunction, the gate can be operated manually:
- Locate the manual release mechanism on the motor unit (refer to the full technical manual for exact location).
- Insert the provided key or handle and turn it to disengage the motor.
- The gate can now be moved by hand.
- To re-engage, reverse the manual release procedure.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your gate opener.
- Monthly: Inspect the gate's movement for any stiffness or obstruction. Clean the gear rack and motor pinion.
- Quarterly: Check all mounting bolts and fasteners for tightness. Verify the proper functioning of the photo cells by obstructing their beam.
- Annually: Have a qualified technician inspect the entire system, including electrical connections, motor, and safety features.
- Keep the area around the gate opener clear of debris, vegetation, and water.
7. Troubleshooting
If you encounter issues with your gate opener, consult the following common troubleshooting steps:
- Gate does not respond to remote:
- Check remote control battery.
- Ensure the receiver is powered and correctly connected.
- Reprogram the remote control if necessary.
- Gate stops or reverses unexpectedly:
- Check for obstructions in the gate's path.
- Clean photo cell lenses and ensure they are aligned.
- Inspect the gate for mechanical binding or damage.
- Motor runs but gate does not move:
- Verify the manual release mechanism is fully engaged.
