3. Specifikationer

4. Opsætning og installation

Before beginning installation, ensure the main power supply to the controller system is disconnected to prevent electrical shock or damage to the components.

4.1. Tilslutning af strømforsyning

Connect the power supply to the designated terminals on the B71/BC board. The board requires an input power supply of 16Vac til 24Vac. Verify the voltage of your power source matches this requirement.

4.2. Batteritilslutning

The B71/BC board is designed to charge two 12Vdc lead-acid batteries connected in series, resulting in a 24Vdc battery pack. Connect the positive and negative terminals of the series-connected batteries to the corresponding battery terminals on the charger board. Ensure correct polarity to avoid damage.

4.3. Jumper Settings for Charging Current

The charging current can be adjusted using the "br" jumper on the board:

• Open "br" jumper: Sets the charging current to 250 mA. This setting is suitable for 1200mAh batteries.
• Closed "br" jumper: Sets the charging current to 400 mA. This optional setting is for fast charging of 4500mAh batteries (B71/BC/EXT models).

Select the appropriate jumper setting based on the capacity of the batteries being charged to ensure efficient and safe charging.

5. Betjeningsvejledning

Once properly installed and connected, the B71/BC charger board will automatically manage the charging process for the connected lead-acid batteries.

5.1. Opladningsproces

The board provides a rated charging voltage of 27.6 Vdc. It continuously monitors the battery voltage and adjusts the charging current according to the selected jumper setting (250 mA or 400 mA) to maintain optimal charge levels.

5.2. Self-Protection Feature

The B71/BC board incorporates a self-protection mechanism. If the battery voltage drops below 19.5 Vdc, the charger will activate its protection mode to prevent deep discharge and potential damage to the batteries.

6. Vedligeholdelse

The B71/BC Battery Charger Board is designed for low maintenance. However, periodic checks can help ensure its longevity and reliable operation:

• Visuel inspektion: Periodically inspect the board for any signs of physical damage, corrosion, or loose connections.
• Renhed: Keep the board free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning. Do not use liquid cleaners.
• Forbindelsesintegritet: Ensure all wire connections to the board are secure and free from fraying or damage.
• Miljøforhold: Ensure the operating environment remains within the specified temperature range (-20°C to +55°C) and is free from excessive humidity.

7. Fejlfinding

If you encounter issues with the B71/BC Battery Charger Board, consider the following basic troubleshooting steps:

• Ingen opladningsindikation:
  • Verify the input power supply (16Vac … 24Vac) is correctly connected and active.
  • Check battery connections for correct polarity and secure contact.
  • Ensure batteries are not excessively discharged (below 19.5 Vdc, which might trigger self-protection).
• Overophedning:
  • Ensure adequate ventilation around the board.
  • Verify the correct battery type and capacity are being used for the selected charging current.
• Incorrect Charging Current:
  • Check the position of the "br" jumper to ensure it matches the desired charging current (250 mA or 400 mA) and battery capacity.

If problems persist after performing these checks, it is recommended to contact qualified technical support.
