4. Instruccions de funcionament
4.1 Procés de càrrega automàtica
The FOXSUR charger is fully automatic with a 3-stage charging process. Once connected to a battery and plugged into power, it will automatically detect the battery type (6V or 12V) and begin charging.
- Stage 1: Desulfation (if needed): Applies a high-frequency pulse charge to break down lead sulfate crystals that may have built up on discharged batteries.
- Stage 2: Bulk Charge: Charges the battery at its maximum rate (2 Amps) until it reaches approximately 80% capacity.
- Stage 3: Float Charge: Once the battery is fully charged, the charger switches to a lower voltage to maintain the battery at 100% capacity without overcharging. This allows the charger to be left connected indefinitely.
4.2 Informació de la pantalla LCD
The backlit LCD display provides real-time feedback:
- Voltage (V): Mostra el volum actual de la bateriatage.
- Corrent (A): Shows the charging current in Amperes.
- Estat de càrrega: An animated battery icon indicates the charging progress.
- Bateria plena: Displays 'FUL' when the battery is fully charged.
- Error (ERO): Indicates a fault condition (e.g., reverse polarity, short circuit).
- Repair Mode (PUL): Indicates the pulse repair function is active.
- End Repair (End): Indicates the pulse repair cycle is complete.
