• Condicións ambientais: Ensure the controller is installed in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.

6 Solución de problemas

This section addresses common issues you might encounter with your Tracer 3215BN controller.

6.1 Controller Not Powering On

• Comprobar a conexión da batería: The controller requires a minimum battery voltage to power on. Ensure the battery is properly connected and has sufficient charge. If the battery is completely discharged, the controller may not power on until an external 12V source or sufficient solar input is provided to raise the battery voltage.
• Verificar polaridade: Confirm that the battery connections are made with correct polarity.
• Inspect Fuses/Breakers: Check any inline fuses or circuit breakers between the battery and the controller.

6.2 No Charging Indication

• Comprobar a conexión do panel solar: Ensure solar panels are correctly connected to the PV terminals with proper polarity.
• Verify Solar Input Voltage: Mida o vol. de circuíto abertotage of your solar panels to ensure it is within the controller's acceptable range (Max 150V).
• Sunlight Conditions: Ensure there is adequate sunlight reaching the solar panels.

6.3 Load Not Working

• Check Load Connection: Verify that the load is correctly connected to the load terminals.
• Modo de control de carga: Ensure the load control mode is set appropriately (e.g., manual ON, or correct timer settings).
• Batería Voltage: Se batería voltage is too low, the controller may disconnect the load to protect the battery.
• Protección contra sobrecarga: Check if the load current exceeds the controller's rated load current, triggering overload protection.
