6. Fejlfinding
This section addresses common issues you might encounter with your Tracer 3215BN controller.
6.1 Controlleren tænder ikke
- Tjek batteriforbindelse: 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.
- Bekræft polaritet: 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
- Check Solar Panel Connection: Ensure solar panels are correctly connected to the PV terminals with proper polarity.
- Verify Solar Input Voltage: Mål det åbne kredsløb voltage of your solar panels to ensure it is within the controller's acceptable range (Max 150V).
- Sollysforhold: 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.
- Belastningskontroltilstand: Ensure the load control mode is set appropriately (e.g., manual ON, or correct timer settings).
- Batteri Voltage: Hvis batteri voltage is too low, the controller may disconnect the load to protect the battery.
- Overbelastningsbeskyttelse: Check if the load current exceeds the controller's rated load current, triggering overload protection.
