Establishing a Default Display

4-line LC Display
Default Display of a
Graphic Display
Procedure
5-46
The default display is the display appearing automatically after the initialization of the
processor system. There are two types of displays, the 4-line LC display and the
graphic display.
Under normal conditions, the so-called default display is the default image in the relay
display. It shows operating information and/or measured values of the protected
equipment. Depending on the relay type, a number of predefined basic displays are
available. Using the
(see example in the following figure), causing it to appear as the default display under
normal conditions.

In the idle state the so-called default display appears on the display of the device as a
continuous display. It can be configured by the user. Normally, a schematic plan of the
feeder is chosen as a basis so that a graphical overview of the switching state of the
station is always available. It is not possible to operate the switching objects via this
default display. However, the default display can be supplemented by further
information, e.g. the most important measured operational values (current and voltage
in the feeder) can continuously be displayed.
When the device is delivered, it might provide one or more pre-assembled default
displays (for example, see Figure 5-46). These can be modified or replaced to adapt
to the actual substation conditions. However, it is also possible to display other
information than the station image on a default display. The display, for example, can
be used to view a variety of operational measured values.
Under normal conditions, a preset image is shown as the default display. The layout
of this default display may be configured by the user. In general, a single-line diagram
of the protected system is designed as the default display in order to show a
continuous graphical image of the switching condition of the protected equipment.
Operation of switching devices from this display is not possible. The display, however,
may be enhanced with additional information. So, for example, the most significant
operating values (system currents and voltages) may be displayed continuously.
As delivered, the relay shows a basic default image (see Figure 5-46) which may be
modified or replaced to show the actual equipment conditions. It is also possible,
however, to show information in addition to the single-line diagram. The display may
also be used, for example, to show a number of measured values.

display. The basic procedure is described in Section 4.9. For detailed information,
consult the Display Editor Manual (order number E50417–H1176–C095).
A precondition for modification or creation of dynamic objects within this display is, the
information which is to appear must be configured in the configuration matrix (see
Section 5.2), i.e. the information of the respective lines in the 'HVWLQDWLRQ
and keys, one of the displayed images may be selected
