- Zero-crossing switching for contact and lamp protection, extending the lifespan of energy-saving lamps.
- Galvanically isolated universal control voltage.
- Very low operating noise.
- Adjustable return delay time from 2 to 120 minutes.
- Control LED indicator.
4. Setup and Installation
The ESR12NP-230V+UC is designed for DIN rail mounting within an electrical distribution board. Ensure adequate space and ventilation according to local regulations.
4.1 Mounting
- The device has a width of 1 module unit and a mounting depth of 58 mm.
- Snap the impulse switch onto a standard 35mm DIN rail in your electrical panel.
- Ensure it is securely fastened.
4.2 Wiring
Refer to the wiring diagram provided with the product packaging for specific connection details. General wiring principles are as follows:
- Connect the main power supply (230V) to the designated input terminals.
- Connect the lighting circuit (load) to the output terminals. The device features one normally open contact.
- Connect control buttons (pushbuttons) to the control input terminals. The control voltage is 230V.
- The device supports a flash lamp current of up to 150 mA at 230V control input, independent of the ignition voltage.
- Ensure all connections are tight and correctly insulated.
5. Operating Instructions
5.1 Basic Operation (Impulse Function)
- Press a connected pushbutton briefly to turn on the light.
- The light will remain on for the set delay time.
- To turn off the light prematurely, press the pushbutton again briefly.
5.2 Setting the Return Delay Time
The return delay time can be precisely adjusted from 2 to 120 minutes using the rotary knob on the front of the device. Rotate the knob to select the desired duration. The scale is marked in minutes.
5.3 Continuous Light Function
To activate continuous light, press and hold the pushbutton for approximately 3 seconds. The light will remain on until manually switched off or until a maximum duration (e.g., 3 hours, depending on specific model configuration) is reached.
5.4 Warning Before Switch-Off
Before the light automatically switches off at the end of the set delay or continuous light period, the control LED will flash (e.g., after 15 minutes with a locked button, or as a warning for the impending switch-off). This provides a visual alert to users.
5.5 Power Failure Behavior
In the event of a power supply failure, the device is designed to default to the "off" state for safety.
6. Maintenance
The Eltako ESR12NP-230V+UC impulse switch is designed for long-term, maintenance-free operation. However, periodic checks are recommended:
- Cleaning: Ensure the device is free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Inspection: Periodically inspect the wiring connections for tightness and signs of wear or damage.
- Functionality Test: Occasionally test the impulse and delay functions to ensure proper operation.
For any repairs, contact qualified personnel or Eltako customer support.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power supply; faulty wiring; defective pushbutton; device malfunction. | Check main circuit breaker. Verify all wiring connections. Test pushbutton. If issues persist, consult a qualified electrician. |
| Light does not turn off. | Delay time set too long; continuous light function active; faulty pushbutton; device malfunction. | Check delay time setting. Briefly press pushbutton to cancel continuous light. Test pushbutton. If issues persist, consult a qualified electrician. |
| Control LED not working. | No power; device malfunction. | Check power supply. If power is present and device functions otherwise, the LED may be faulty. |
| Device makes unusual noise. | Internal component issue. | Disconnect power immediately and contact a qualified electrician or Eltako support. |
