Wiring Diagrams
The device supports both 3-wire and 4-wire connection methods for staircase lighting. Refer to the diagram below for detailed wiring instructions. Professional installation is highly recommended.
General Wiring Steps:
- Mount the TM-C20E onto a standard DIN rail.
- Connect the main Live (L) and Neutral (N) power supply wires to the corresponding L and N terminals on the timer.
- For the control circuit (e.g., push button for staircase light):
- Connect a Live wire to one side of your push button switch.
- Connect the other side of the push button switch to terminal '1' on the TM-C20E.
- For the load (e.g., light fixture):
- Connect the Neutral wire from the main supply to one terminal of your light fixture.
- Connect terminal '2' on the TM-C20E to the other terminal of your light fixture.
- Ensure all connections are tight and properly insulated.
- Restore power and test the functionality.
Note: The provided wiring diagram for '3 Wire connection' and '4 Wire connection' appears functionally identical in terms of external connections to the timer (L, N, 1, 2) and the light. Always consult a qualified electrician if unsure about wiring configurations.
7. Operation
Setting the Delay Time
Rotate the blue dial on the front of the timer to select the desired delay duration. Available settings are 0.5, 5, 10, 15, and 20 minutes.
Function Modes
The blue slide switch typically offers two modes:
- Timer Mode (Clock Icon): In this mode, the connected light will turn on when the external push button is pressed and remain on for the duration set by the dial, then automatically turn off.
- Fix On Mode (Light Bulb Icon): This mode acts as a manual override. When selected, the connected light will remain continuously on, bypassing the timer function. This is useful for extended illumination needs.
Activating the Timer
Once wired and configured, a momentary press of the external push button connected to terminals 1 and L will activate the timer, turning on the light for the preset duration.
8. Maintenance
- Keep the device clean and free from dust. Use a dry, soft cloth for cleaning.
- Do not use abrasive cleaners or solvents.
- Periodically check wiring connections for tightness, especially after initial installation.
- Ensure the operating environment remains within the specified temperature and humidity ranges.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on when button is pressed. | No power to timer; incorrect wiring; faulty light bulb; timer in 'Fix On' mode (if light is off). | Check power supply; verify wiring against diagram; replace bulb; switch to 'Timer' mode. |
| Light stays on continuously. | Timer in 'Fix On' mode; faulty timer relay. | Switch to 'Timer' mode; if problem persists, timer may need replacement. |
| Light turns off too soon or too late. | Incorrect time setting; internal timing issue. | Adjust the time setting dial; if inconsistent, timer may be faulty. |
| Timer does not respond to button presses. | Loose connection to button; faulty button; timer in 'Fix On' mode. | Check button wiring; test button functionality; switch to 'Timer' mode. |
10. User Tips
- After installation, test all time settings (0.5M, 5M, 10M, 15M, 20M) to ensure the timer functions as expected for your specific application.
- Consider the 'Fix On' mode for situations where temporary continuous lighting is needed, such as during cleaning or maintenance.
