5. Käyttöohjeet

5.1 Ensimmäinen käynnistys:

After completing all wiring, double-check connections for correctness and security. Power on the battery pack. The BMS should initialize, and its status indicator (if present) will illuminate.

5.2 Bluetooth Monitoring:

Download the official DALY BMS mobile application from your device's app store. Enable Bluetooth on your mobile device and open the app. The app should detect the BMS. Connect to the BMS to view real-time battery data, including cell voltages, kokonaisvoltage, current, temperature, and protection status. You can also adjust certain parameters through the app.

5.3 Communication Interfaces (RS485/CAN/UART):

For integration with external systems (e.g., PC host, industrial controllers), connect the appropriate communication cable (RS485, CAN, or UART) to the BMS. Refer to the DALY communication protocol documentation for detailed information on data exchange and control commands.

6. Huolto

• Säännöllinen tarkastus: Tarkista säännöllisesti kaikkien johtojen liitännät kireyden ja korroosion tai vaurioiden varalta.
• Laiteohjelmistopäivitykset: Check the DALY official website or app for any available firmware updates. Follow the provided instructions carefully for any update procedures.
• Puhtaus: Keep the BMS unit clean and free from dust and debris to ensure proper heat dissipation.
• Ympäristöolosuhteet: Ensure the BMS operates within its specified temperature and humidity ranges.

7. Vianmääritys

• BMS ei käynnisty: Verify all main power connections (B-, P-, B+) and ensure the battery pack has sufficient voltage. Check the fuse if applicable.
• Cell Imbalance: If the app shows significant cell voltage differences, ensure the balance wires are correctly connected and not damaged. The active balancing function will work to equalize cells over time.
• Overcurrent/Short Circuit Protection Triggered: Disconnect the load immediately. Identify and resolve the cause of the overcurrent or short circuit before reconnecting.
• Viestintäongelmat: Ensure Bluetooth is enabled and the app is updated. For wired communication (RS485/CAN/UART), check cable connections and verify communication settings.
• Sensing Circuitry Issues: In rare cases, strong electrical impulses (e.g., from lightning strikes or severe electrical transients) can damage sensing circuitry. Ensure the battery pack and BMS are adequately shielded and grounded in environments prone to such events. If sensing issues persist, contact DALY support.
