The device has 3 screen display modes, named “standby
mode, “standard” mode and “XXL” mode.
The “standby” mode (figure 1) is the display mode shown
when no transaction is in progress. While a transaction is
being made, the screen will show the “standard” mode
(figure 2) or the “XXL” (figure 3) according to the device
configuration (see the “menu configuration” section for
more details).
Depending on the screen mode, the unit address (1), the
fluid volume dispensed (2), the progress status bar of the
transaction (3) or the indicator which shows that the
solenoid valve is open (4), will be displayed.
