5. Instal·lació
Avís de seguretat important: Installation should only be performed by a qualified electrician. Ensure the main power supply is disconnected before commencing any wiring work. Failure to do so may result in electric shock or damage to the device.
- Muntatge: The device is designed for DIN rail mounting. Securely attach it to the DIN rail within your electrical panel.
- Cablejat: Consulteu el diagrama de cablejat a continuació.
- Connect the incoming Live (L) and Neutral (N) wires to the "IN" terminals at the top of the protector.
- Connect the outgoing Live (L) and Neutral (N) wires from the "OUT" terminals at the bottom of the protector to your load or downstream circuit breaker.
- Assegureu-vos que totes les connexions estiguin ben ajustades i segures per evitar contactes solts i sobreescalfament.
- Verificació: After wiring, double-check all connections for correctness and security before restoring power.

6. Funcionament
Once installed and powered on, the device will display the current voltage on its LCD screen. You can adjust the overvoltage i undervoltage protection thresholds using the control buttons.
- Viewing Current Voltage: The LCD continuously displays the real-time circuit voltage.
- Entering Setting Mode: Manteniu premut el botó SET button for approximately 3-5 seconds until the display starts flashing.
- Adjusting Overvoltage Threshold (U>):
- While in setting mode, press the SET button repeatedly to cycle through parameters until "U>" (Overvoltage) is displayed and flashing.
- Utilitza el Amunt (▲) i Avall (▼) buttons to adjust the desired overvoltage protection value (221V-290V).
- Adjusting Undervoltage Threshold (U<):
- Premeu el botó SET button again to cycle to "U<" (Undervoltagi).
- Utilitza el Amunt (▲) i Avall (▼) buttons to adjust the desired undervoltage protection value (150V-219V).
- Desar la configuració: After adjusting all desired parameters, wait for approximately 5-10 seconds without pressing any buttons. The device will automatically save the settings and exit the setting mode.
- Restabliment manual: En el cas d'un voltage fault, the device will trip. Once the voltage returns to normal, it will automatically reconnect. If manual intervention is required, power cycle the device.
7. Manteniment
The SINOTIMER SVP-915-40A is designed for minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Inspecció periòdica: Periodically inspect the device and its wiring for any signs of damage, loose connections, or discoloration.
- Neteja: Mantingueu el dispositiu net i lliure de pols i brutícia. Feu servir un drap sec i suau per netejar-lo. No utilitzeu netejadors líquids.
- Condicions ambientals: Ensure the device is operated within its specified environmental conditions (temperature, humidity) to prevent malfunction.
- Verificació professional: If you suspect any malfunction or damage, consult a qualified electrician for inspection and repair. Do not attempt to repair the device yourself.
8. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| El dispositiu no s'encén. | No hi ha alimentació d'entrada; cablejat incorrecte; error intern. | Check main power supply. Verify wiring connections according to the diagram. If problem persists, consult a qualified electrician. |
| El dispositiu s'encén amb freqüència. | Voltage fluctuations in the circuit; protection thresholds set too narrow. | Monitor circuit voltage to confirm fluctuations. Adjust overvoltage/undervoltage thresholds slightly wider if necessary, ensuring they remain within safe limits for your appliances. |
| LCD display is blank or erratic. | Power issue; internal display fault. | Check power supply. Power cycle the device. If the issue continues, the device may require professional inspection. |
| Cannot adjust settings. | Not in setting mode; buttons malfunctioning. | Press and hold the SET button for 3-5 seconds to enter setting mode. If buttons are unresponsive, the device may be faulty. |
