4. Instalace a zapojení
VAROVÁNÍ: Installation must be performed by a qualified electrician in accordance with all local and national electrical codes. Ensure power is disconnected before installation to prevent electric shock.
- Namontujte zvtage protector on a standard DIN rail within a distribution cabinet or control box.
- Connect the incoming Live (L) and Neutral (N) lines from the power source to the 'IN' terminals of the protector.
- Connect the outgoing Live (L) and Neutral (N) lines from the 'OUT' terminals of the protector to the load (e.g., appliances, electrical circuits).
- It is recommended to install a circuit breaker (power switch) before the protector and an air switch (miniature circuit breaker) after the protector for additional safety and circuit isolation.
- Ujistěte se, že všechny spoje jsou bezpečné a řádně izolované.

5. Operating Instructions and Settings
After successful installation and power-up, the device will display the current voltage and current. You can adjust the protection parameters using the front panel buttons.
5.1. Nastavení parametrů
- Press the 'SET' button to enter the parameter setting mode. The first parameter will flash.
- Use the 'Up' (triangle up) and 'Down' (triangle down) buttons to adjust the value of the flashing parameter.
- Press 'SET' again to move to the next parameter.
- Repeat steps 2 and 3 for all parameters: Overvoltage (>U), Undervoltage (<U), Overcurrent (>A), and Reset Time (t).
- After setting all parameters, press and hold the 'SET' button for a few seconds until the display stops flashing to save the settings and exit the setting mode.
5.2. Default and Adjustable Ranges
- Přepětítage Trip Value: Adjustable from 130V to 300V (Default: 270V).
- Podpětítage Trip Value: Adjustable from 80V to 210V (Default: 170V).
- Overcurrent Trip Value: Adjustable from 1A to 63A (Default: 63A).
- Resetovat čas: Adjustable from 1 second to 999 seconds (Default: 5 seconds).
5.3. Ruční ZAP/VYP
The device can be manually turned ON or OFF using the dedicated ON/OFF button on the front panel.

- Kontrola připojení: Ensure all wiring connections remain tight and secure.
- Test funkčnosti: If possible and safe to do so, periodically test the protection functions by simulating an overvoltage, podpaltage, or overcurrent condition (e.g., using a test power supply) to confirm the device trips as expected.
POZOR: Always disconnect power before performing any maintenance or inspection to avoid electrical hazards.
9. Řešení problémů
If you encounter issues with your JOYELEC Voltage Protector, refer to the following common troubleshooting steps:
| Problém | Možná příčina | Řešení |
|---|---|---|
| Zařízení se nezapne. | Žádné vstupní napájení; nesprávné zapojení; vnitřní chyba. | Zkontrolujte napájení a jistič. Ověřte zapojení kabeláže. Pokud problém přetrvává, kontaktujte podporu. |
| Zařízení se často vypíná. | svtage/current fluctuations are common; protection settings are too sensitive. | Monitor power quality. Adjust overvoltage/podvoltage/overcurrent settings to appropriate levels for your application. |
| Display shows incorrect voltage/aktuální. | Measurement inaccuracy; sensor issue. | Compare reading with a calibrated multimeter. If significantly different, contact support. |
| Device does not reset automatically. | Reset time setting is too long; fault condition still present. | Check reset time setting. Ensure the voltage/current has returned to normal operating range. |
