4. Setup and Installation
4.1 DIN Rail Mounting
The TAXNELE timer switches are designed for easy installation on a standard 35mm DIN rail, ideal for household electrical panels or control cabinets.
- Ensure all power to the circuit is disconnected at the main breaker.
- Align the timer switch with the DIN rail.
- Press firmly until the device clicks securely into place on the rail.
4.2 Wiring Instructions
IMPORTANT: Incorrect wiring can cause damage to the device or lead to electrical hazards. Consult a qualified electrician if you are unsure.
- Identify the terminals on your specific model (SUL181H or SUL181D).
- Connect the live (L) and neutral (N) power supply wires to the corresponding input terminals.
- Connect the load (e.g., light, motor) to the output terminals, ensuring the correct live and neutral connections.
- Refer to the wiring diagrams below for detailed connections.
Note on Wiring Diagrams:
- SUL181H: Features terminals 1, 2, 3, 8 for main power and load, and additional terminals 4, 5, 6, 7 for motor control (M). The diagram shows L connected to 1, N to 2, and the load connected between 3 and 8.
- SUL181D: Features terminals L, N, 1, 3 for power and load. The diagram shows L connected to L, N to N, and the load connected between 1 and 3.
- Always double-check the specific terminal markings on your device.
5. Operating Instructions
5.1 Setting the Current Time
Rotate the central dial clockwise until the current time aligns with the small arrow indicator on the timer face. The dial represents a 24-hour cycle.
5.2 Programming On/Off Times
The timer features small segments around the dial. Each segment represents a minimum time unit:
- SUL181H: Minimum setting unit is 30 minutes.
- SUL181D: Minimum setting unit is 15 minutes.
To program an ON period, push the corresponding segments outwards. To program an OFF period, leave the segments pushed inwards. The timer will activate the connected load when the segments are pushed outwards and deactivate it when they are inwards, according to the 24-hour cycle.
5.3 Manual Override Switch
Some models may include a manual override switch (often a small lever or button) to temporarily switch the load ON or OFF, overriding the programmed settings. Refer to your specific model for this feature.
5.4 Battery Backup
The timer includes a built-in battery that provides backup power for up to 150 hours after a 24-hour recharge period. This ensures that your programmed settings are retained during power outages.
6. Maintenance
- Keep the timer switch clean and free from dust. Use a soft, dry cloth for cleaning.
- Do not use abrasive cleaners or solvents.
- Periodically check wiring connections for tightness and signs of wear.
- Ensure the timer is not exposed to extreme temperatures or humidity, which can affect its accuracy and lifespan.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Timer not switching load ON/OFF | Incorrect programming (segments not pushed out/in correctly). No power to the timer. Faulty wiring. Load exceeding contact capacity. | Verify that the program segments are correctly set for ON/OFF times. Check power supply to the timer. Inspect wiring connections for looseness or errors. Consult wiring diagrams. Ensure the connected load does not exceed 16A/1000W. |
| Timer dial not moving | No power to the timer. Internal mechanical fault. | Check power supply. The dial should move when powered. If power is present and the dial doesn't move, the unit may be faulty. Contact support. |
| Program settings lost after power outage | Battery backup not fully charged or faulty. | Allow the timer to be powered for at least 24 hours to fully charge the internal battery. If the issue persists, the battery may need replacement or the unit is faulty. |
8. User Tips
- For applications requiring very precise timing, consider the SUL181D model with its 15-minute minimum setting unit.
- When setting the current time, rotate the dial only clockwise to avoid damaging the internal mechanism.
- Regularly check the timer's accuracy, especially after long power outages, and reset the current time if necessary.
9. Warranty and Support
