GYSFLASH S 4.12
Translation of the original
instructions
Do not operate on 230V - risk of explosion!
GENERAL DESCRIPTION
The GYSFLASH S 4.12 is ideal to charge most lead-acid batteries, often used for cars and many other vehicles. These batteries
can be of many types eg: GEL (gel electrolyte), AGM (absorbed glass mat), WET, MF (Maintenance Free), CA (Calcium)...
This charger has been designed to charge 12V batteries (6*2V elements) from 1.2 Ah to 90 Ah, or for floating charge up to 130 Ah.
START UP
1. Connect the charger to the battery using the proper accessory (clamps, lugs, etc...).
2. Plug the charger to the mains (single phase 100-127 Vac 50-60Hz).
3. Select the mode by pressing the
button. After roughly 5 seconds, the charge starts automatically.
4. During the charge, the device indicates the charge’s progress. When the indicator
blinks, the battery is ready to start the
vehicle. Once the indicator
stays on, the battery is completely charged.
5. The charge can be interrupted at any time by unplugging the mains plug or pressing the
button.
6. After charging, disconnect the charger from the mains, then disconnect the charger’s connections from the battery.
CHARGE MODES
• Modes and Options:
CHARGE mode (14.4V/0.8A) :
Mode designed for lead-acid batteries, 12V from 1.2 Ah to 15Ah. 7 step automatic maintenance cycle.
CHARGE mode (14.4V/4A) :
Mode designed for lead-acid batteries, 12V from 15 Ah to 90 Ah and up to 130 Ah for floating charge. 7 step automatic
maintenance cycle.
COLD/AGM Option (14.7V) :
Modifies the charging voltage at 14.7V to charge the battery during cold weather (Less than 5°C) or for some AGM
batteries or batteries with caps.
SUPPLY Mode (13.6 V/4 A):
This mode enables to use the charger as a stabilised power supply, with a voltage regulated at 13.6 V. This mode is
designed for providing a power supply to demonstration vehicles and can also be used to replace a vehicle’s battery
while maintaining the system’s memory. With this mode, there is no time limit.
When the
indicator is on, the volyage is properly regulated. If the
indicator blinks, this means that the current
absorbed by the battery is higher than the charger’s maximum current (4 A) and that the battery might end up being
discharged.
To access to this mode, press 5 seconds on the
button. When this mode is selected, the three blue indicators for
mode selection light on. And after roughly 5 seconds, the charge starts automatically.
• Charging curve :
The GYSFLASH S 4.12 use an 7 step charging curve which guarantees optimal performance for your battery.
