4. Navodila za uporabo
4.1. Polnjenje akumulatorja
- Izberite Battery Voltage: Uporabite voltage selector switch (typically labeled 12V/24V) to match the voltage baterije, ki se polni.
- Izberite način polnjenja: 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.
- Začetek polnjenja: 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.
- Monitor Polnjenje: Periodically check the ammeter. When the current drops to a very low level (near zero), the battery is fully charged.
- Konec polnjenja: Turn off the power switch. Disconnect the charger from the mains power supply. Then, disconnect the BLACK (-) clamp, followed by the RED (+) clamp iz baterije.
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.
- Priključitev na baterijo: Follow the connection steps as described in Section 3.4.
- Izberite Battery Voltage: Zagotovite voltage selector switch matches the vehicle's battery voltage (12 V ali 24 V).
- Select Booster Mode: Set the switch to the 'START' or 'BOOST' position.
- Poskus začetka: 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.
- Prekini povezavo: Once the engine starts, immediately turn off the charger's power switch. Disconnect the BLACK (-) clamp, then the RED (+) clamp.
5. Vzdrževanje
- Čiščenje: Keep the charger clean and dry. Wipe the exterior with a soft, damp krpo. Ne uporabljajte topil ali abrazivnih čistil.
- Kabel in Clamp Pregled: Redno pregledujte polnilne kable inampPreverite morebitne znake poškodb, obrabe ali korozije. Poškodovane komponente takoj zamenjajte.
- Zamenjava varovalke: The unit is equipped with a fuse for protection. If the charger stops working, check the fuse (visible on the front panel, labeled 'FUSE'). Replace it only with a fuse of the same type and rating as specified by the manufacturer. Always disconnect from mains power before replacing the fuse.
- Shranjevanje: Store the charger in a cool, dry place, away from direct sunlight and moisture, when not in use. Ensure cables are neatly coiled.
6. Odpravljanje težav

- Preverite, ali je napajalni kabel varno priključen v vtičnico.
- Verify the mains power supply is active.
- Inspect the fuse. Replace if blown (refer to Section 5).
- Battery Not Charging / Low Ammeter Reading:
- Zagotovite, da je clampso varno priključeni na sponke baterije.
- 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 voltage je izbran.
- 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.
