GENERAL DESCRIPTION
Your GYSFLASH is a professional multifunctional charger with Inverter technology. Designed to support the batteries of demonstration vehicles or during the diagnostic work, it also guarantees an ideal quality of charge for the maintenance of the most advanced models. This charger can be fitted with cables up to 8 m long. Changing the charging cables requires recalibration (see page 21). It is considered a fixed device not a mobile product. Your GYSFLASH is supplied with a software that includes 4 different modes to choose from: · Charging mode: dedicated to the charging of lead-acid (sealed, liquid, AGM…) or lithium (LiFePO4) starter batteries. · Power mode | Diag+ : Supplies the energy required during diagnostic work on the vehicle. · Power mode | Showroom : Maintains the charge of the battery and supplies the energy required when using the consumers of a demonstration vehicle. · Tester Mode: Used to check the state of the battery and test the vehicle starting system and alternator.
Your GYSFLASH is SMART! The original features of your GYSFLASH can be extended by adding specific charging modes and profiles using the USB port and custom settings (see page 23). Your GYSFLASH also offers the possibility to recover data from several hundred charging operations on your USB stick for analysis on a spreadsheet. Additional modules (such as printer, Ethernet port, etc.) can also be connected to the charger via its dedicated module socket.

It is strongly recommended not to use the «no battery» function if a battery is present. This function disables the «Integrated charging» function, as well as some of the protections such as abnormal undervoltage protection or disconnection detection. In this configuration, reverse polarity can damage the vehicle electronics.

· «Integrated charging» function: The SHOWROOM mode (outside of the «no battery» function) incorporates an automatic charging algorithm adapted to all types of batteries (lead and lithium), in order to guarantee an optimal charge level for demonstration vehicles. This function is perfectly compatible with the presence of consumers on the battery.
