General Description; Charge Mode - GYS GYSFLASH 40-12 FV Manual De Instrucciones

This manual contains safety and operating instructions. Read it carefully before using the device for the first time and keep it in a
safe place for future reference.

GENERAL DESCRIPTION

The GYSFLASH 40-12 FV provides a high powered stabilised power supply incorporating SMPS (Switch Mode Power Supply) tech-
nology. Designed to sustain 12V battery (liquid/AGM/gel) for vehicles during diagnostic work. This device will also ensure an ideal
charging cycle for battery maintenance for the most modern vehicles and battery types. It can be fitted with cables up to 2x5m in
16mm². Changing charging cables requires recalibration (see page 14). It is considered a fixed device not a mobile product.
These devices have 5 modes including 2 that are hidden:
• Charge Mode: to charge liquid or gel electrolyte batteries (lead, lead Calcium, lead Calcium-silver, AGM...) from 10 Ah to 500 Ah
in 12V.
• Supply mode « Diag + »: GYSFLASH supply up to 40A to ensure compensation of current used by high-energy consumers (engine
fan, window regulator, electronic suspension, etc). In this mode the voltage can be precisely adjusted.
• Supply mode « Showroom »: ensure current compensation when using electrical features of a demonstration vehicle (window
regulator, heating, morrors, etc) enabling permanent display of the vehicle. In this mode the voltage can be precisely adjusted.
• « Change battery » mode: ensures a stabilised power supply to the vehicle during battery replacement to preserve memory
settings. By default this mode is inactive and doesn't appear in the mode list.
• « Power Supply » mode: This mode is intented for experimented user only. By default this mode is inactive and doesn't appear
in the mode list. This mode enables to use the charger as a powerful stabilised power supply with regulated voltage and adjustable
maximum current.
This device has an automatic restart feature enabling in Charge, Showroom and Power Supply modes to automatically restart the device
in case of power cut. The function «Lock Showroom», if activated, restricts the device to Showroom Mode only, to facilitate its use
for vehicles demonstrators.
START UP
Connect the charger to the mains. With «Flexible Voltage» technology, this battery charger works on any
1
voltage in the range 85V to 265V (50/60Hz).
Turn the switch to «ON».

Select the required mode. By default the charger will automatically select the last setting.
• The "Mode" key enables access to several menus :
• To access the "configuration" menu press the "mode" key

CHARGE MODE

This product will charge the battery safely even if the battery is still in the vehicle.
Ensure that the correct sequences are followed.
Charge configuration :
Before starting to charge the battery, ensure that the charger has been correctly set (battery voltage, charging curve and battery
capacity).
Several charging curves are available :
• Easy: simplified curve, suitable for every lead battery and which for it is not required to know the battery capacity. However for an
optimized charge, it is recommended when possible to use the liquid or gel/AGM batteries charging curves.
• Liquid: charging curve for vented battery (lead, lead calcium, lead calcium-silver, etc). For this charging curve the battery capacity
in Ah must be selected.
• Gel/AGM: charging curve for sealed battery (gel, maintenance free, AGM...). For this charging curve the battery capacity in Ah must
be selected.
• Expert: charging curve type IU
By default this curve is inactive and doesn't appear in the curve list of the CHARGE mode.
WARNING: According to the configuration of the expert curve (see page 15), it can be necessary to disconnect vehicle's battery
before starting the charge in order to protect the electronic of the vehicle.
