6.3 Illumination of the Display
If none of the control keys is pressed, the display illumination will switch off once the set
‘return time illumination’ (set in the menu tree at ‘Par/Conf/LOC’) has elapsed. Press
any one of the control keys to turn the display illumination on again. The control action
that is normally triggered by that key will not be executed. Reactivation of display
illumination is also possible by way of a binary input.
If continuous illumination is desired, set the ‘return time illumination’ function to ‘blocked’.
6.4 Control at the Panel Level
At the Panel level, the user can move from one Panel type to another by pressing the
page key (in one direction only) or the ‘left’ and ’right’ keys (in both directions).
6.4.1 Bay Panel
Information displayed on
the Bay Panel
Figure 6-3 shows an example of a Bay Panel. The top line shows the unit type on the
left and the current time of day on the right.
The bay shown below in single-pole representation is a function of the set bay type. The
symbols shown in the table on the next page are used to represent the switchgear units
and other external devices as well as the state of the switchgear units. The user can
switch between character sets 1, 2, and 3. Character set 3 is identical to character set 1
in as-delivered condition but can be replaced by a user-defined character set – by using
a special ancillary tool. The symbols of character set 2 are used in the following
description.
The fourth line from the bottom shows (in abbreviated form) whether a bay interlock is
active. The third line from the bottom indicates whether remote or local control is
permitted. In the example shown here, remote control is activated. The two lines at the
bottom contain measured value data. The arrows to the right of the measured value
data indicate that additional measured values can be called up by pressing the ‘up’ or
’down’ keys.
