3. Produttu Finituview
The Eltako NLZ61NP-UC is a compact timer relay designed for series installation. It features adjustable delay functions and robust terminal connections.
Figura 1: Eltako NLZ61NP-UC Timer Relay. This image displays the blue, octagonal-shaped timer relay with its various terminals and adjustment potentiometers. Visible labels include 'CE', 'Eltako NLZ61NP-UC', 'A1-A2 8-230V~', 'L-N 230V~', 'RV', 'AV', '12min', 'μ 10A/250V~', and connection points for L, N, and 3.
Cumpunenti chjave:
- A1-A2 Terminals: Cuntrollu voltage input (8-230V~).
- L-N Terminals: Power supply input (230V~).
- 3 Terminal: Switched output (max. 10A/250V~).
- RV Potentiometer: Adjustable delay on release timer (0-12 minutes).
- AV Potentiometer: Adjustable delay on activation timer (0-12 minutes).
4. Setup è Installazione
The NLZ61NP-UC is designed for series installation within an electrical distribution board or similar enclosure.
Passi di stallazione:
- Disconnection d'energia: Ensure the main power supply to the installation area is completely disconnected before beginning any work.
- Muntamentu: Mount the timer relay securely in the desired location, typically on a DIN rail within a suitable enclosure.
- Wiring Power Supply (L-N): Connect the live (L) and neutral (N) wires of the 230V~ power supply to the corresponding L and N terminals on the device.
- Wiring Control Voltage (A1-A2): Cunnette vi lu cuntrollu voltage (8-230V~) to the A1 and A2 terminals. This voltage triggers the timing functions.
- Wiring Output (3): Connect the load to be switched to the '3' terminal. The other side of the load should be connected to the neutral (N) or live (L) depending on the circuit design. Ensure the load's current and voltage requirements do not exceed 10A/250V~.
- Verificate e cunnessione: Double-check all wiring for correctness and security to prevent short circuits or malfunctions.
- Ripristina l'energia: Once all connections are verified, restore power to the circuit.
5. Operating Instructions
The Eltako NLZ61NP-UC features two adjustable timing functions: delay on release (RV) and delay on activation (AV).
Setting the Timer Functions:
- RV (Delay on Release): Use the RV potentiometer to set the desired delay time after the control voltage (A1-A2) is removed. The output will remain active for the set duration before switching off. The range is 0 to 12 minutes.
- AV (Delay on Activation): Use the AV potentiometer to set the desired delay time after the control voltage (A1-A2) is applied. The output will activate after the set duration. The range is 0 to 12 minutes.
- Aghjustamentu: Rotate the respective potentiometer (RV or AV) to align the indicator with the desired time value on the scale (0, 2, 4, 8, 12 minutes).
The specific behavior of the relay (e.g., which delay function is active or if both can be combined) depends on the internal configuration and application. Refer to the detailed wiring diagram provided with the product for specific operational modes.
6. Mantenimentu
The Eltako NLZ61NP-UC Timer Relay is designed for long-term, maintenance-free operation under normal conditions.
- Pulizia: Sè necessariu, asciugate delicatamente l'esternu di u dispusitivu cù un pannu asciuttu è dolce. Ùn aduprate micca detergenti abrasivi o solventi.
- Ispezione: Periodically inspect the wiring connections for any signs of loosening or damage. Ensure the device is free from dust and debris.
- Nisuna parte riparabile da l'utilizatori: The device contains no user-serviceable parts. Do not attempt to open or repair the unit.
7. Risoluzione di prublemi
If the timer relay does not function as expected, consider the following common issues:
| Prublemu | Causa Possibile | Soluzione |
|---|---|---|
| U dispusitivu ùn risponde micca | No power supply (L-N) or control voltage (A1-A2). Incorrect wiring. | Check power supply and control voltage. Verify all wiring connections according to the diagram. |
| Output not switching | Load exceeding current/voltage rating. Incorrect timing setting. Faulty load. | Ensure load is within specifications. Adjust RV/AV potentiometers. Test the load independently. |
| Tempu incorrectu | Potentiometer set incorrectly. | Re-adjust the RV or AV potentiometer to the desired time. |
If problems persist, contact a qualified electrician or Eltako customer support.
