Step 2: Electrical Connection
Connect the motors, flashing light, and photocells to the control unit according to the wiring diagram provided in the detailed installation manual (not included in this summary). Ensure all connections are secure and insulated. The system operates on a safe 24V low voltage supply.
Step 3: Programming and Synchronization
Once mechanical and electrical installations are complete, proceed with programming the system. This involves teaching the gate's travel limits and synchronizing the remote controls. The integrated Wi-Fi module allows for easy setup and control via the H'Access smartphone application.
Operating Instructions
Remote Control Operation
Use the provided rolling code remote controls to open and close your gate. Pressing the designated button will initiate the gate's movement. The system supports full opening and partial (pedestrian) opening modes.
Smartphone App Control (H'Access)
Download the H'Access application on your smartphone (available on App Store and Google Play). The integrated Wi-Fi module allows you to control your gate remotely, monitor its status, and receive alerts. The app provides a convenient interface for managing your gate from a distance of up to 30 meters in open field conditions.
Opening Modes and Features
- Full Opening: Opens both gate leaves completely.
- Partial (Pedestrian) Opening: Opens one gate leaf for pedestrian access.
- End-of-Travel Slowdown: The gate slows down before reaching its fully open or closed position for smooth operation.
- Obstacle Detection: The system is designed to stop if an obstacle is detected during movement, enhancing safety.
- Automatic Closing: Configurable automatic closing after a set time.
- Manual Release: In case of power outage, the gate can be manually unlocked for operation.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your gate motorization system.
- Cleanliness: Keep the motors and photocells clean and free from debris, dust, and insects.
- Lubrication: Periodically check and lubricate the articulated arms' pivot points as recommended in the full product manual.
- Inspection: Regularly inspect all mounting points, cables, and connections for signs of wear, corrosion, or damage.
- Photocell Alignment: Ensure the infrared photocells are always clean and perfectly aligned for proper obstacle detection.
- Battery Check (Optional): If backup batteries are installed, check their charge and condition periodically.
Troubleshooting
This section addresses common issues you might encounter. For more complex problems, please contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Gate does not respond to remote control. | Dead remote battery, remote out of range, system not powered, remote not programmed. | Replace remote battery, move closer to gate, check power supply, re-program remote. |
| Gate stops or reverses unexpectedly. | Obstacle detected by photocells, gate obstruction, motor overload. | Clear photocell path, remove physical obstructions, check gate for free movement. |
| Gate opens partially or not fully. | Travel limits not correctly set, mechanical resistance. | Re-program travel limits, check gate hinges and movement for friction. |
| Flashing light does not work. | Bulb failure, wiring issue, power supply problem. | Check bulb, inspect wiring connections, verify power to light. |
