Referring to the operating and display elements in Figure 2-4:
1. MENU key
This key activates the main menu.
2. LC-Display (LCD)
In the LCD the processing and device information can be illustrated in a control
display or displayed in the form of text in various lists. Commonly displayed infor-
mation includes the position of the switchgears, measured values, counter values,
binary information regarding the condition of circuit breakers, status of the device,
protection information, general reports, and alarms.
3. Navigation keys
These keys serve for navigation through operating menus.
4. Control keys
These keys serve for controlling the process. They are located below the LCD.
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). The 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.
