5. Operating Instructions
5.1 Automatic Charging
The GYSFLASH 30.12 PL features an integrated temperature sensor that automatically adjusts charging parameters based on the ambient temperature, optimizing charging efficiency and battery life.
5.2 Mode Selection
Use the "MODE" button on the charger's front panel to select the appropriate charging program for your battery type:
- Pb (Lead-Acid): Select this mode for 12V lead-acid batteries, including GEL, AGM, liquid, and calcium types. Suitable for capacities from 15 Ah to 375 Ah.
- LiFePO4 (Lithium Iron Phosphate): Select this mode for 12V lithium iron phosphate batteries. Suitable for capacities from 7 Ah to 375 Ah.
5.3 Charging Current Selection
After selecting the battery type, choose one of the three available charging currents (7 A, 15 A, or 30 A) based on the battery's capacity and desired charging speed. Higher currents charge faster but should be appropriate for the battery's specifications.
5.4 Showroom Mode
This mode is designed to provide a stable power supply of up to 30A. It is ideal for maintaining the battery charge in vehicles displayed in showrooms or during diagnostic procedures, preventing battery drain without overcharging.
5.5 Supply Mode
The Supply Mode provides a stable on-board power supply to the vehicle's electrical system. This is particularly useful for maintaining power to vehicle electronics when the battery is being changed or during software updates, preventing loss of settings or data.
6. Charging Process
- Connect the charger to the battery terminals, ensuring correct polarity (red to positive, black to negative).
- Plug the charger's power cord into a mains power outlet.
- Press the "MODE" button to select the appropriate battery type (Pb for lead-acid or LiFePO4 for lithium).
- Select the desired charging current (7 A, 15 A, or 30 A) based on your battery's requirements.
- The charger will automatically begin the charging cycle. Monitor the progress indicators on the display.
- Once the charging cycle is complete, first disconnect the charger from the mains power outlet.
- Then, disconnect the black (-) clamp from the battery, followed by the red (+) clamp.
7. Maintenance
- Keep the charger clean and dry. Wipe the casing with a soft, damp cloth. Do not use harsh chemicals or abrasives.
