Nastavení a instalace
Follow these steps to correctly install and connect your XH-M609 module:
- Příprava zapojení: Ensure all wires are appropriately sized for your application and have proper insulation.
- Connect Battery Input: Connect the positive terminal of your 12-36V battery to the VIN+ terminal and the negative terminal to the VIN- terminal of the module. Ensure correct polarity.
- Připojení výstupu zátěže: Connect the positive terminal of your load (e.g., inverter, light, motor) to the VOUT+ terminal and the negative terminal to the VOUT- terminal of the module.
- Ověřte připojení: Double-check all wiring for secure connections and correct polarity before applying power.
- Použít napájení: Once all connections are verified, connect the battery to power the module. The digital display should illuminate, showing the current battery voltage.

Důležité: Always disconnect the battery before making or changing any wiring connections to prevent short circuits or damage.
Návod k obsluze
Nastavení Voltage Prahové hodnoty:
The XH-M609 module allows you to set two critical voltage thresholds: the low voltage disconnect (LVD) point and the voltage recovery (VR) point.
- Vstupte do režimu nastavení: Stiskněte a podržte Soubor button (left button) for approximately 3 seconds until the digital display starts flashing. This indicates you are in setting mode.
- Set Low Voltage Disconnect (LVD) Point: While the display is flashing, press the Soubor button briefly. The display will show the current LVD value. Use the Nahoru/dolů button (right button) to adjust this value. This is the voltage at which the load will be disconnected.
- Set Voltage Recovery (VR) Point: After setting the LVD point, press the Soubor button again briefly. The display will show the current VR value. Use the Nahoru/dolů button to adjust this value. This is the voltage at which the load will be reconnected. The VR value must always be higher than the LVD value to prevent rapid cycling.
- Uložit nastavení: After setting both values, wait for approximately 5 seconds without pressing any buttons. The display will stop flashing, and the new settings will be automatically saved. The module will then return to displaying the current battery voltage.

Logika operace:
- Když je baterie objtage drops below the set LVD point, the module will disconnect the load to prevent further discharge.
- Když je baterie objtage rises above the set VR point (e.g., after charging), the module will automatically reconnect the load.
Údržba
The XH-M609 module requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Udržujte v čistotě: Periodically clean the module with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners.
- Kontrola připojení: Pravidelně kontrolujte všechna kabelová spojení, abyste se ujistili, že jsou bezpečná a bez koroze.
- Vyhněte se drsnému prostředí: Protect the module from direct sunlight, excessive heat, moisture, and corrosive substances.
