Referring to the operating and display elements in Figure 2-1:
1. Display (LCD)
The LCD shows processing and device information as text in various lists. Com-
monly displayed information includes measured values, counter values, binary in-
formation regarding the condition of circuit breakers, status of the device, protec-
tion information, general reports, and alarms.
2. Navigation keys
These keys serve for navigation through operating menus.
3. MENU key
This key activates the main menu.
4. ESC and ENTER keys
These keys serve to escape from specific menues or execute changes (such as
setting changes).
5. Numerical keys
These keys serve for entry of numerical values, such as limit value settings.
6. Function keys
Four function keys (F1 to F4) allow the quick and simple execution of frequently
used actions. Typical applications include, for example, jumping to a particular po-
sition in the menu tree such as the fault data in the Trip Log or the measured val-
ues. Three of the function keys were already configured in our factories, for dis-
playing the lists of the event logs (F1), the operational measured value (F2) and
the trip logs of the last system fault (F3). Key F4 is not allocated. All function keys
are freely configurable. Next to the keypad, a labeling strip is provided on which
the user-specified key functions may be written.
