4. Instruccions de funcionament
4.1. Càrrega de la bateria
- Seleccioneu Battery Voltage: Utilitzeu el voltage selector switch (typically labeled 12V/24V) to match the voltage de la bateria que s'està carregant.
- Seleccioneu el mode de càrrega: The unit may have MIN/MAX or 1/2 settings for charging current. Select MIN for slower, gentler charging or MAX for faster charging. Refer to the battery manufacturer's recommendations for optimal charging rates.
- Comença a carregar: Turn on the power switch (often labeled 'ON/OFF' or 'START'). The ammeter on the front panel will indicate the charging current. The current will gradually decrease as the battery charges.
- Càrrega del monitor: Periodically check the ammeter. When the current drops to a very low level (near zero), the battery is fully charged.
- Final de la càrrega: Turn off the power switch. Disconnect the charger from the mains power supply. Then, disconnect the BLACK (-) clamp, followed by the RED (+) clamp de la bateria.
4.2. Engine Boosting (Starting Assistance)
The boosting function provides a high current for a short period to assist in starting an engine with a discharged battery. Do not use the booster function for prolonged periods.
- Connectar a la bateria: Follow the connection steps as described in Section 3.4.
- Seleccioneu Battery Voltage: Assegureu-vos que el voltage selector switch matches the vehicle's battery voltage (12V o 24V).
- Select Booster Mode: Set the switch to the 'START' or 'BOOST' position.
- Intent d'inici: Turn the ignition key to start the engine. Do not crank the engine for more than 5-10 seconds. If the engine does not start, wait for at least 60 seconds before attempting again to allow the charger to cool.
- Desconnectar: Once the engine starts, immediately turn off the charger's power switch. Disconnect the BLACK (-) clamp, then the RED (+) clamp.

- Verify the mains power supply is active.
- Inspect the fuse. Replace if blown (refer to Section 5).
- Battery Not Charging / Low Ammeter Reading:
- Assegureu-vos que la bateria clamps estan connectats de manera segura als terminals de la bateria.
- Confirm the correct battery voltage (12V or 24V) is selected on the charger.
- Check if the battery is severely discharged or faulty. Some deeply discharged batteries may not accept a charge immediately.
- The battery may be fully charged if the current is very low.
- Booster Function Not Working:
- Ensure all connections are secure and the correct voltages selecciona e.
- The vehicle's battery might be completely dead, or there might be a larger issue with the vehicle's starting system.
- Allow the unit to cool if it has recently activated thermal protection.
- Charger Shuts Down During Operation:
- This indicates the thermal protection has activated due to overheating. Allow the unit to cool down in a well-ventilated area before resuming use. Reduce the load or charging rate if possible.
