Ensure all wire connections are tight and secure. Use appropriate wire gauges for the load current.
5. Operating Instructions
5.1. Setting the Timer Duration
The timing duration can be adjusted using the rotary dial on the front of the device. Use a small screwdriver to turn the dial to the desired time setting, ranging from 0.5 minutes to 12 minutes.
5.2. Manual Override Switch
The timer features a manual override switch, typically located below the timing dial. This switch allows for continuous operation or manual OFF, bypassing the timed function. Refer to the symbols on the device for specific positions (e.g., timed operation, continuous ON, continuous OFF).
5.3. Special Functions
- Pre-warning Function: The timer may provide a visual indication (e.g., a brief flicker of the light) before the end of the timing period, allowing users to react before the light switches off.
- Long Duration Function: A specific input or sequence might activate a 1-hour timing period, useful for extended lighting needs.

- Check if the main power supply is connected and active.
- Verify all wiring connections (L, N, B, 4) are correct and secure.
- Ensure the control push-button is functioning correctly.
- Check the manual override switch position.
- Incorrect timing duration:
- Adjust the rotary dial to the desired time setting.
- Load not switching off:
- Check the manual override switch position; it might be set to continuous ON.
- Ensure the load does not exceed the maximum specified rating.
