- Verify the gate structure is strong enough to support the opener.
- Confirm adequate space for the opener's movement.
6.2 Mounting the Actuator and Control Box
Mount the actuator to the gate and post using the provided brackets and hardware. Ensure the actuator is level and allows for full gate travel without obstruction. The control box should be mounted in a secure, weather-protected location near the gate, allowing for easy access to wiring.
6.3 Wiring the Control Board
Refer to the wiring diagram for correct connections. The control box contains a 110V/24V transformer, allowing direct connection to a standard 110V AC power supply. Ensure all connections are secure and insulated.

6.4 Travel Setting
Before initial use, it is essential to complete the travel setting for the electromachnical limit switch. This process defines the fully open and fully closed positions of your gate. Consult the detailed instructions provided in the separate quick start guide or the full manual for the specific steps to set the travel limits.
7. Operating Instructions
7.1 Basic Operation
Use the provided remote control to open and close the gate. Pressing the button once will initiate the gate movement. Pressing it again during movement will stop the gate. A third press will reverse the gate's direction.
7.2 Advanced Functions
- Speed Adjustment: The control board allows for adjustment of the gate's opening and closing speed. Refer to the control board diagram (Figure 6.2) for the specific adjustment potentiometers.
- Obstacle Detection Sensibility: The sensitivity of the obstacle detection can be adjusted to prevent damage to the gate or objects. Adjust this setting carefully to ensure safety without causing false stops.
- Pedestrian Mode: This feature allows the gate to open partially, providing access for pedestrians without fully opening the gate.
- Auto-Close Function: The gate can be programmed to automatically close after a set period of time. Ensure the area is clear before enabling this function.
Detailed instructions for adjusting these functions are typically found in the control board's specific programming guide.
8. Maintenance
Regular maintenance ensures the longevity and reliable operation of your gate opener.
- Monthly: Inspect the gate and opener for any loose bolts, worn parts, or signs of corrosion. Clean any debris from the gate's path and the opener mechanism.
- Quarterly: Check the gate's balance and ensure it moves freely by hand. Lubricate moving parts of the gate and opener as recommended by the manufacturer.
- Annually: Have a qualified technician inspect the entire system, including electrical connections and safety features.
9. Troubleshooting
This section addresses common issues you might encounter with your gate opener.
| Problem | Possible Cause | Solution |
