When Free is selected the figure shows the single-line diagram of the last scheme selected in light
grey, as this is the meaning base free configuration is starting from.
The picture shown in light grey in Free configuration is not fully relative to the actual single-line

scheme, since with free selection some components might not be applicable (e.g. the earth switch
can be de-selected but the picture will not show it).
14.4.3 HW Configuration
By checking the HW modules available it is possible to configure the HW according to the Electronic
Device (IED) integrated in the CB and to activate the relative Tabs.
Possible selections are:
Digital I/O: ticked by default, this activates the Output, Input Mapping Tabs.
LCD Panel HMI: optional HMI module, enables you to operate the CB and to access information
displayed on the LCD by a menu navigation. It shows the panel single-line diagram according to
the selection and available inputs.
When LCD Panel HMI is selected, the Local/Remote selection Key and Close/Open commands
from local functions are provided by the HMI and the meanings are not configurable in the DI
mapping Tab (see picture below).
Fig. 31
Trip Signal and Anomaly Reset function can still be performed both from HMI with the Reset
pushbutton and by DI (by default DI 11).
In default configurations, without HMI, the #Local/Remote selection is not available - see figure
below. This means that the IED will be in Global mode (both Local and Remote commands are
accepted).
Fig. 32
To define a Local/Remote selection without HMI, it is necessary to use the Free configuration and
to select on #Local/Remote selection Key meaning the available DI10.
When the input is supplied above the activation threshold the IED will go to Remote mode and
local command will be not executed; otherwise it will be in Local mode.
Communication: not ticked by default, it activates the Communication Tabs.
