- Condicións ambientais: Verifique que o ambiente de funcionamento se manteña dentro dos rangos de temperatura e humidade especificados.
9 Solución de problemas
If you encounter issues with your BAC06A charger, consider the following basic troubleshooting steps:
- Charger Not Powering On (Power LED Off):
- Comprobe a fonte de alimentación de entrada de CA.
- Verify the AC input wiring (L and N terminals).
- Inspect the internal fuse (10A). If blown, replace with a fuse of the same rating.
- Charging LED Not Illuminating:
- Asegúrate de que a batería estea conectada correctamente coa polaridade correcta.
- Comprobe o vol. da bateríatage. If the battery is fully charged, the charging LED may not illuminate as the charger enters float mode.
- Verify the charging voltage setting using the VOLTS ADJ. potentiometer.
- Baixa corrente de carga:
- Comproba o AMP ADJ. potentiometer setting.
- Ensure the battery is not already near full charge.
If problems persist after performing these checks, please contact your supplier or a qualified technician for assistance.
