tions with the

Figure 7-48
Set Status at the Front Panel (example)
Move the cursor, using the
and
keys, to each of the second (Input Ignore) and
fifth (Control Block) columns of the switching device for which a status change is de-
sired. Entries in this table can only be made in these two columns.
Press the
key. A selection window is opened that displays the meaning of the
field and the change options that are available.
The second column is reserved for setting Input Ignore (I); the fifth for setting the out-
put block (O). The first, third, and fourth columns can only be read in this menu.
The example in Figure 7-48 shows the position for the circuit breaker (52) was tagged
(T) after the input ignore (I) was set, which means the message input was de-coupled
from the system. The output block is active (O), so the command output is also de-
coupled from the system. For the disconnect switch and the ground switch, no limita-
tions are set.
Select the desired changes using the
and
keys, and confirm with the
key.
Enter Password No. 2 (for non-interlocked switching) and acknowledge with the
key.
A safety inquiry appears: “
$UH\RXVXUH"
” If the response is “
<(6
”, and provided
the return routing is allowed, then the display gives an appropriate message.
To return to the
%5($.(56:,7&+
level, press the
key as necessary. Press the
key to return to the
0$,10(18
.
Note:
Input ignored only works for physical inputs! Do not set the block for indications cre-
ated by CFC.
