5. Modes de funcionament

The charger features 6 distinct working modes, selectable via the 'MODE' button on the device. The LCD screen will indicate the currently selected mode.

• CAR/TRUCK Mode: Designed for large batteries (30Ah-150Ah). Provides fast charging with a maximum output of 12V 8A for 12V batteries and 24V 4A for 24V batteries.
• Mode de motocicleta: Designed for small batteries (6Ah-30Ah). Provides a small charge with a maximum output of 1.5A (12V/24V). This mode can also be used to maintain or trickle charge larger batteries if desired, instead of the CAR/TRUCK mode.
• Mode AGM: Specifically optimized for AGM and Calcium batteries.
• Mode de reparació: A pulse repair function designed to help restore drained and sulfated batteries. This mode uses high-frequency and low-frequency pulse technology.
• Mode d'estiu: Automatically selected when the internal temperature is detected to be above 10°C (50°F). Adjusts charging parameters for warmer conditions.
• Mode d'hivern: Automatically selected when the internal temperature is detected to be below 10°C (50°F). Adjusts charging parameters for colder conditions.

6. Charging Process and LCD Display

6.1. 3-Stage Càrrega

The FOXSUR charger employs a fully automatic 3-stagprocés de càrrega electrònica:

1. Càrrega ràpida: Delivers maximum current to quickly bring the battery to approximately 80% capacity.
2. Top-Off: Reduces current to safely bring the battery to 100% charge, preventing overcharging.
3. Càrrega de degoteig: Maintains the battery at full charge with a small, continuous current, ideal for long-term connection.

6.2. Informació de la pantalla LCD

The LCD screen provides real-time feedback on the charging status:

• Vol. De càrregatage i actual: Mostra el volum actualtage i amperage being delivered to the battery.
• Temperatura de càrrega: Shows the internal temperature of the charger.
• Mode de càrrega: Indicates the active charging mode (e.g., CAR/TRUCK, Motorcycle, AGM, Repair, Summer, Winter).
• 'ERO' Indicator: Displays 'ERO' if there is a reverse connection or an output short-circuit.
• Indicador de nivell de bateria: A visual representation of the battery's charge level.

6.3. Estimated Charging Times

The following table provides estimated charging times based on battery capacity and output current. Actual times may vary depending on battery condition and ambient temperature.
