3- DISPLAY AND COMMAND COMPONENTS:
3-1 MAIN DISPLAY/COMMAND PANEL:
The panel has a basic panel which houses all the compulsory signalling and command functions provided for by
standards UNI EN54-2 and 54-4.
Using the panel unit it is also possible to control the auxiliary command and display functions and control the configuration
of the panel (at access level 3).
The panel groups the signals and commands into three logical sections (see Fig.1):
The part on the left (
A
) houses all the general signals and commands, the central part (
B
), consisting of an alphanumeric
display and a keyboard, makes it possible to carry out detailed displays and control specific commands (display details,
control zone/line deactivation etc.), and finally the part on the right (
C
) displays the state of the 32 zones/sectors which
can be controlled from the panel.
