11.2. Keyboard/Display
11.2.1. Introduction
The electronic relay has a keyboard and display to set and
view the protection and control parameters. Moreover, the
display provides information of the system's meterings,
alarms and control signals in real time.
As with the different parts of the firmware platform, the
Display is organised in a tree structure, meaning navigation
is more straightforward and intuitive for users.
The user can navigate through the navigation screens to
reach the data screens.
The purpose of the navigation screens is to organise the
display in a tree structure, meaning they do not contain any
type of data. New navigation or data screens may depend
on this type of screens, in accordance with the how the
structure is defined.
The data screens, on the other hand, are screens which
show different types of data (settings, meterings, digital
signals, information, etc.). No other screen will depend on
this type of screen, since they are final screens within the
display tree structure. There is the option of a double data
screen. For example, in the metering data screens with
modules and angle, the data screens will be double, i.e.
one with information of the module, and the other with
information of the angle. The “right” button is used for
switching between them.
The keyboard has 6 keys:
1
SET
2
ESC
3
Up
4
Down
5
Left
6
Right
Figure 11.16. Keyboard
The “up” and “down” keys are used to move around between
same level screens. The “right” key is used to enter lower-
level screens (whenever this screen has lower levels). The
“left” or “ESC” key, on the other hand, is used to pass to the
upper level screen it depends on.
