Walfront XH-M609 Digital Low Voltage Disconnect Module User Manual

1. Konec produktuview

The Walfront XH-M609 is a digital low voltage disconnect module designed to protect 12-36V DC batteries from over-discharge, over-charge, over-current, and short-circuit conditions. It automatically disconnects the load when the battery voltage drops below a user-defined threshold and reconnects when the voltage recovers, ensuring battery longevity and system stability. This module is suitable for various battery types, including lithium batteries.

3. Components and Connections

The XH-M609 module features clearly labeled input and output terminals, a digital display for voltage readings, and two push-buttons for configuration.

• Input Terminals (+IN, -IN): Connect to the 12-36V DC battery. Ensure correct polarity.
• Output Terminals (+OUT, -OUT): Connect to the load that requires protection. Ensure correct polarity.
• Digitální displej: Shows current voltage readings and configuration values.
• Levé tlačítko: Používá se pro svtage calibration and setting the low voltage přerušení.
• Pravé tlačítko: Used for setting the reactivate voltage (hysteresis) and the debounce timer.
• Červená LED: Indicates when the output relay is active (load is connected).

4. Nastavení a konfigurace

Before connecting the module to your battery and load, ensure all connections are secure and correctly polarized. It is recommended to perform initial setup with a stable power supply and a multimeter for accurate calibration.

Kroky konfigurace:

1. Calibrate Input Voltage čtení:
   • Connect the module to your power source (battery).
   • Změřte skutečný objemtage of your power source using a multimeter.
   • On the XH-M609 module, press and hold the Left Button for approximately 3 seconds until the displayed numbers begin to flash.
   • Use the Left and Right Buttons to adjust the module's displayed voltage to match the reading on your multimeter.
   • Release the buttons and wait for the display to stop flashing to save the calibration.
2. Set Low Voltage Cut-Off (LVC):
   • From the main voltage displej, single-click the Left Button to momentarily display the current LVC value.
   • To change the LVC, double-click the Left Button (two quick clicks). The middle decimal point on the display will flash.
   • Use the Left and Right Buttons to adjust the desired low voltagpráh mezní hodnoty.
   • Release the buttons and wait for the display to stop flashing to save the setting.
3. Set Reactivate Voltage (Hysteresis):
   • From the main voltage displej, single-click the Right Button to momentarily display the current reactivate voltage value. This value represents the voltage difference above the LVC at which the load will be reconnected.
   • To change this value, double-click the Right Button (two quick clicks). The middle decimal point on the display will flash.
   • Use the Left and Right Buttons to adjust the desired reactivate voltagE. Napřample, if LVC is 12V and reactivate voltage is set to 2V, the load will reconnect at 14V.
   • Release the buttons and wait for the display to stop flashing to save the setting.
4. Set Debounce Timer (Reactivate Time):
   • From the main voltage displej, press and hold the Right Button for approximately 3 seconds. The rightmost decimal point will flash, and the display will show the timer value in minutes.
   • Use the Left and Right Buttons to adjust the debounce timer. A value of '0' means instantaneous reconnection. A value of '1' means a 1-minute delay before reconnection, and so on.
   • Release the buttons and wait for the display to stop flashing to save the setting.
5. Reset All Values to Default:
   • To restore all settings to their factory defaults, press and hold both the Left and Right Buttons simultaneously until the display indicates a reset.

Důležitá poznámka: All settings are saved automatically to the module's memory once the display stops flashing after an adjustment. Disconnecting power will not erase your configured settings.

5. Principy fungování

Once configured, the XH-M609 module operates autonomously. When the battery voltage is above the set Low Voltage Cut-Off (LVC), the module's relay remains closed, allowing power to flow to the connected load. The red LED will be illuminated, indicating the output is active.

Pokud je baterie objtage drops to or below the LVC, the module will open the relay, disconnecting the load to prevent further discharge and potential damage to the battery. The red LED will turn off. The module will then monitor the battery voltagE. Když je baterie objtage recovers to the LVC plus the set Reactivate Voltage (hysteresis), and after the Debounce Timer (if set) has elapsed, the module will close the relay, reconnecting the load. This cycle ensures the battery operates within safe voltage limity.

6. Péče a údržba

• Podmínky prostředí: Operate the module within a dry environment, away from excessive moisture, dust, and extreme temperatures.
• Čištění: If necessary, gently clean the module with a soft, dry cloth. Avoid using liquids or abrasive cleaners.
• Spojení: Pravidelně kontrolujte všechna kabelová spojení, abyste se ujistili, že jsou bezpečná a bez koroze.
• Fyzické poškození: Avoid dropping or subjecting the module to physical shock, which can damage internal components.

7. Průvodce odstraňováním problémů

• Modul se nezapne:
  • Ověřte, že vstupní objemtage je v rozsahu 12–36 V DC.
  • Check input wiring for correct polarity (+IN to positive, -IN to negative) and secure connections.
  • Ensure the power source (battery) is charged and providing sufficient voltage.
• Nesprávný svtage Odečet na displeji:
  • Perform the voltage calibration procedure as described in Section 4.1 using a reliable multimeter.
  • Check for loose connections at the input terminals.
• Load Not Disconnecting at LVC / Not Reconnecting:
  • Verify the Low Voltage Cut-Off (LVC) setting (Section 4.2) is correctly configured.
  • Verify the Reactivate Voltage (Hysteresis) setting (Section 4.3) is correctly configured.
  • Check the Debounce Timer setting (Section 4.4). A longer timer will delay reconnection.
  • Ensure the load is properly connected to the output terminals and is not drawing excessive current that could cause a short-circuit protection activation.
  • If the red LED is not illuminating when the voltage is above LVC + Hysteresis, the internal relay may be faulty.
• Module Malfunctions or Behaves Erratically:
  • Try resetting the module to factory defaults (Section 4.5).
  • Ensure the module is not exposed to electromagnetic interference.
  • If issues persist, the module may be faulty and require replacement.
