5. Setup u Installazzjoni

Proper installation is crucial for the safe and correct operation of the BMS. Refer to the wiring diagram provided with your specific battery pack and BMS model for precise connections. The following are general steps:

Prepare the Battery Pack: Ensure all individual battery cells are balanced and at a similar voltage level before connecting the BMS.
Qabbad il-Wajers tal-Bilanċ: Connect the balance wires from the BMS to each cell of your LiFePO4 battery pack in the correct order (B0, B1, B2, B3, B4 for a 4S pack). Always connect the lowest voltage first (B0 to the negative terminal of the first cell) and proceed upwards. Warning: Incorrect balance wire connection order can severely damage the BMS.
Connect Main Power Wires:
- Connect the main negative terminal of the battery pack to the B- terminal on the BMS.
- Connect the main positive terminal of the battery pack to the P+ terminal on the BMS.
- Connect the load/charger negative terminal to the P- terminal on the BMS.
Connect NTC Temperature Sensor: Attach the NTC sensor to a central cell or area of the battery pack to monitor temperature.
Qabbad il-Modulu Bluetooth: Plug the Bluetooth module into the designated port on the BMS.
Qawwa Inizjali: After all connections are verified, apply power to the system. The BMS should activate.

For detailed wiring diagrams, please refer to the manual included in your product packaging or contact DALY support.

Il-BMS mhux qed jixgħel / L-ebda output	Incorrect wiring (main power or balance wires). Pakkett tal-batterija voltage baxx wisq. BMS in protection mode (e.g., overdischarge).	Double-check all wiring according to the diagram. Charge the battery pack using a compatible charger. Check app for protection status and clear faults if safe.
Kwistjonijiet ta 'konnessjoni Bluetooth	Bluetooth module not properly connected. Kwistjonijiet ta' interferenza jew distanza. App not updated or incompatible.	Ensure Bluetooth module is securely plugged in. Move closer to the BMS; reduce interference. Update the app or try reinstalling it.
Ċelloli tal-batterija żbilanċjati	Passive balancing not sufficient for severe imbalance. Faulty cell.	Allow more time for passive balancing. Consider an external active balancer for severe cases. Inspect individual cells for damage or degradation.
Overcurrent protection triggers frequently	Load current exceeds BMS rating. Short circuit fit-tagħbija. BMS current setting too low.	Reduce the load or use a BMS with a higher current rating. Inspect load for short circuits. Adjust overcurrent settings in the app (if applicable and safe).

If the problem persists after attempting these solutions, please contact DALY customer support.
