4.1. Terminal Descriptions
- L (Live): Connects to the live wire of your 230V AC power supply.
- N (Neutral): Connects to the neutral wire of your 230V AC power supply.
- S1, S2 (Signal Cable): Output terminals for connecting to your garage door opener's control input.
- S3, S4 (Sensor Cable): Input terminals for connecting the magnetic sensor cable to detect door status (open/closed).
5. Setup and Installation
5.1. Electrical Installation
IMPORTANT: Ensure power is OFF before proceeding. A neutral wire (N) is required for this module.
- Disconnect Power: Turn off the main power supply to your garage at the circuit breaker.
- Access Switch Box: Remove your existing garage door wall switch from its mounting box.
- Wire the Module:
- Connect the Live (L) wire from your power supply to the 'L' terminal on the module.
- Connect the Neutral (N) wire from your power supply to the 'N' terminal on the module.
- Connect the control wires from your garage door opener (typically the wires that go to your existing wall switch) to the 'S1' and 'S2' terminals on the module. The module acts as a dry contact switch.
- Connect the magnetic sensor cable to the 'S3' and 'S4' terminals. The sensor detects the open/closed status of the garage door.
- Mount the Module: This module is designed for easy installation under the switch in various types of hollow wall boxes, including standard European switch boxes. Carefully place the module into the wall box behind the existing switch.
- Install Magnetic Sensor: Mount the two parts of the magnetic sensor on your garage door and door frame. Ensure they are aligned and close enough to each other when the door is closed, and separate when the door is open. This allows the module to accurately detect the door's status.
- Restore Power: Once all connections are secure and the module is safely housed, restore power at the circuit breaker.
