General Functions; Service Menu - Würth BLG 12V 50 A Traduction Des Instructions De Service D'origine

If the support mode is required for, e.g., commer-
cial vehicles with 24 volts, you have to switch the
voltage to 24 V by pressing the gear symbol in the
menu for 3 seconds (3.8.3.2 Adjusting the charging
parameters). The current values of the output vol-
tage and the output current are permanently visible
in the display.
3.8.5 Current consumption test, exhaus-
ted batteries
At the start of a normal charging process, the
charger will check the current consumption capacity
of the battery and whether it is exhausted. To pass
the test, the battery voltage must have risen above
1.5 volts/cell after 30 minutes. Charging will then
continue automatically. Otherwise, a timeout error
will be issued. While the battery is in the voltage
range of between 0.25 volts/cell and 1.5 volts/
cell, it will automatically be charged gently with a
reduced current.

3.9 Service menu

In this menu, settings can be made that affect other
functions of the device. The service area is a sub-
menu of the settings menu (3.8.3.2 Adjusting the
charging parameters). In the settings menu, touch
the "Service" button for approx. 3 seconds.
