Display Panels
The following display Panels are available with the C232:
Bay Panel
Measured Value Panels, which are called up according to system conditions
Signal Panel
The Bay Panel displays the up-to-date switching state of the selected bay in single-pole
representation. Selected measured values are displayed on the Measured Value
Panels. The system condition determines which particular Panel is called up (examples
are the Operation Panel and the Fault Panel). Only the Measured Value Panels relevant
for the particular design version of the given unit and its associated range of functions
are actually available. The Operation Panel is always available. The Signal Panel
displays the most recent events such as the opening of a switchgear unit.
Menu tree and data points
All data points (setting values, signals, measured values, etc.) are selected using a
menu tree. As the user navigates through the menu tree, the first two lines of the LCD
display always show the branch of the menu tree that is active, as selected by the user.
The data points are found at the lowest level of a menu tree branch. They are displayed
either with their plain text description or in numerically coded form, as selected by the
user. The value associated with the selected data point, its meaning, and its unit of
measurement are displayed in the line below.
List data points
List data points are a special category. In contrast to other data points, list data points
generally have more than one value element associated with them. This category
includes tripping matrices, programmable logic functions, and event logs. When a list
data point is selected, the symbol ‘↓‘ is displayed in the bottom line of the LCD display,
indicating that there is another level below the displayed level. The individual value
elements of a list data point are found at the lower level. In the case of a list parameter,
the individual value elements are linked by operators such as ‘OR’.
