4.1. Indikatorer på kontrolpanelet
- MAGT: Lyser, når opladeren er tilsluttet vekselstrøm.
- MODE knap: Press to cycle through available charging modes (6V, 12V, 24V, COLD TEMP, AGM/REFRESH).
- Voltage Indicators (6V, 12V, 24V): Indicate the currently selected charging voltage.
- Special Mode Indicators (COLD TEMP, AGM/REFRESH): Indicate activation of specific charging programs.
- Charge Progress Indicators (25%, 50%, 75%, 100%): Show the approximate charge level of the battery.
- FEJL: Illuminates if an error occurs (e.g., reverse polarity, short circuit, damaged battery).
5. Opsætning
Follow these steps to prepare your Voltcraft BC-10 for charging.
- Placering af opladeren: Place the charger on a stable, flat surface away from direct sunlight, heat sources, and moisture. Ensure good ventilation.
- Tilslut batteri Clamps:
- Tilslut rød (+) clamp til positiv (+) terminalen på batteriet.
- Tilslut sort (-) clamp til negativ (-) terminalen på batteriet.
Ensure a secure connection. Incorrect polarity will trigger the FAULT indicator.
- Tilslut vekselstrøm: Plug the AC power cable into a standard wall outlet. The POWER indicator on the charger will illuminate.

6. Betjeningsvejledning
Once the charger is set up, follow these steps to begin charging your battery.
- Vælg opladningstilstand: Tryk på MODE button repeatedly to cycle through the available charging programs until the desired voltage (6V, 12V, or 24V) and any special modes (COLD TEMP, AGM/REFRESH) are selected. The corresponding LED indicators will light up.
- Overvåg opladningsfremskridt: The 25%, 50%, 75%, and 100% LEDs will illuminate sequentially to indicate the battery's charge level.
- Opladning fuldført: When the 100% LED is steadily lit, the battery is fully charged. The charger will automatically switch to a maintenance (float) charge mode to prevent overcharging.
- Frakobling af opladeren:
- First, unplug the AC power cable from the wall outlet.
- Frakobl derefter den sorte (-) kabelamp fra batteriets negative pol.
- Til sidst skal du frakoble den røde (+) kl.amp fra batteriets positive pol.
6.1. Special Charging Modes
- COLD TEMP: Use this mode when charging batteries in cold environments (below 5°C / 41°F). This mode adjusts the charging voltage to compensate for temperature effects.
- AGM/REFRESH: This mode is suitable for AGM batteries and can also be used for reconditioning deeply discharged or sulfated batteries. Consult your battery manufacturer's recommendations before using the refresh function.
7. Vedligeholdelse
Proper maintenance ensures the longevity and performance of your charger.
- Rensning: Frakobl opladeren fra alle strømkilder før rengøring. Tør ydersiden af med en blød, tør klud. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Opbevaring: Opbevar opladeren et køligt og tørt sted, når den ikke er i brug. Hold kablerne pænt oprullede for at forhindre skader.
- Kabelinspektion: Regularly inspect the AC power cable and battery clamp cables for any signs of damage, such as cuts or fraying. Do not use the charger if cables are damaged.
8. Fejlfinding
Se dette afsnit for almindelige problemer og deres løsninger.
| Problem | Mulig årsag | Løsning |
|---|---|---|
