With the key it is possible to leave the status messages display. The operation display now
appears without the word status message. Only when new information arrives does status message
appear again in the bottom line of the operation display.
Additionally, input error indications or further parameters may be stated, which are self-explaining
in connection with the menu heading.
As shown before, automatic switch to this display is made if more than one minute has passed
since the last key has been pressed. The operation display is exited by simple acknowledgement
(OK key).
3.1.6 LINE DIAGRAM
The line diagram has the same functionality as a page recorder. The „writing pen“ and therefore
the current measurement value are found on the Y axis. The line diagram is scrolled left pixel by
pixel. Measured value collection supplies one measured value each second. Because the time axis
is resolved in 90 pixels, the following values result for the time bases from 1.5min up to 3h:
TIME BASE MEASURED VALUES PER TIME-PIXEL
1.5 min 1 *
30 min 20
1 h 40
3 h 120
*) for this resolution, no band display is possible
TAB. 8 LINE DIAGRAM TIME BASE
There are two display modes: band and average value display. In case of band display, each measu-
red value is displayed unfi ltered. The number of measured values displayed for each time pixel
is shown in the above table.
In case of average value display, the average value is formed from several measured values and
displayed in one pixel.
The „windmill“ icon on the LBA display shows current data transfer between LBA and Power
Controller. In case of still or non-existant icon, the data transfer is faulty.
To exit the line diagram, the OK key must be pressed twice.
3.1.7 LAST FUNCTION
If the OK key is pressed during operation display, then the LBA will display the main menu. If the
lowest menu item last function is selected, then the menu is displayed which has been processed
last before operation display.
3.1.8 STATUS LINE
The status line is the lowest line of each menu. It looks like this:
1P VAR Trafo UxU Example for status line

1P, 2P or 3P for the Power Controller type
