4. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your gate opener. Consult the detailed diagrams in the printed manual for specific mounting instructions.
- Mounting the Opener: Securely mount the gate opener unit on a stable, level surface adjacent to the gate, ensuring proper alignment with the gate's movement path. The unit should be positioned to allow the drive chain to engage correctly with the gate.
- Installing the Drive Chain: Attach the drive chain along the length of the gate, ensuring it is taut but not overly tight. The chain should engage with the opener's sprocket.
- Wiring Connections: Connect the power supply and accessories (infrared sensors, remote receiver) to the control board. Ensure all wiring is done according to electrical safety standards. The signal line from the receiver and any power lines should be at least 22 AWG (0.5 mm²) thick.
- Infrared Sensor Placement: Install the infrared sensors on opposite sides of the gate opening, ensuring they are aligned and unobstructed. These sensors provide crucial obstacle detection for safety.
- Limit Switch Adjustment: Adjust the limit switches to define the gate's fully open and fully closed positions.

5.1. Remote Control Operation
The included remote controls allow you to open and close the gate from up to 98.4 feet away. Press the designated button on the remote to activate the gate. The system supports up to 40 remote controls.
5.2. HomeLink Compatibility
The CO-Z CGHL14 is compatible with HomeLink systems found in many vehicles. This allows you to program your car's built-in buttons to control the gate opener, providing convenient access without needing a separate remote.

5.3. Automatic Closing
The system features adjustable auto-close presets of 15, 30, or 45 seconds. Once enabled, the gate will automatically close after the set time has elapsed, provided no obstacles are detected by the infrared sensors.
5.4. Pedestrian Mode
A pedestrian mode allows the gate to open partially (approximately 3.3 feet) for foot traffic, without fully opening the gate. Refer to your control board's programming instructions for activating this feature.

6. Maintenance
Regular maintenance ensures the longevity and reliable performance of your CO-Z gate opener.
- Cleaning: Keep the gate opener unit and infrared sensors clean from dirt, debris, and obstructions.
- Lubrication: Periodically lubricate the drive chain and other moving parts as recommended in the detailed manual to ensure smooth operation and prevent wear.
- Inspection: Regularly check all mounting hardware, electrical connections, and the gate itself for any signs of loosening, corrosion, or damage. Tighten fasteners as needed.
- Weather Resistance: The IP44-rated casing protects the internal components from various weather conditions, including temperatures from -4°F to 158°F. However, extreme weather may require more frequent inspections.

7. Troubleshooting
If you encounter issues with your gate opener, refer to the following common troubleshooting steps:
- Gate Not Moving: Check power supply, ensure emergency release is not engaged, verify remote control battery, and inspect for physical obstructions.
- Gate Reverses Unexpectedly: This often indicates an obstacle. Check infrared sensors for alignment or obstructions. The system is designed to stop and reverse if an obstacle is detected during closing.
- Remote Control Not Working: Check remote battery. Ensure the remote is paired correctly with the opener. Frequency encryption technology protects against unauthorized access, so proper pairing is essential.
- Gate Not Closing Fully/Opening Fully: Re-adjust the limit switches.
For more complex issues or if troubleshooting steps do not resolve the problem, please contact customer support.
