Figure 7-50 Selection Window for Manual Overwriting of a Switch Position, Front Panel
A safety inquiry appears: “$UH\RXVXUH"” Provided manual overwriting is allowed,
a response of “<(6” results in an appropriate message on the display. Acknowledge
the message by pressing the key again.
Manual overwriting is cancelled if the process is restricted because, for example, “LQ
SXWLJQRUHG” is not set (see Sub-section 7.3.3). Manual overwriting is also canceled
if the user aborts the procedure. The display provides an appropriate message if man-
ual overwriting is canceled. Acknowledge the message by pressing the key.
Return to the %5($.(56:,7&+ sub-menu using the key, or the 0$,10(18 by
pressing the key.

7.3.3 Set Status
A feature of the 7SJ62 that is especially useful during testing and commissioning of
the device is the capability of temporarily removing the coupling between a switching
device and the 7SJ62, or between the SCADA and the 7SJ62, without physically dis-
connecting the equipment. This type of separation is also necessary, for instance, if a
switch position feedback message is not functioning properly (refer to Sub-section
7.3.2). The menu item 6(767$786 is used to perform the decoupling.
The menu displays a list of all planned switching devices and associated status infor-
mation identified by a letter. The letters have the following meanings:
• T Device is tagged (manually overwritten).
• I Input ignored, which means the acquisition of an input status is de-coupled from
the process (from the switch-gear).
• B Blocked, which means data transmissions to the central device (or SCADASCA-
DA) are blocked.
• C Chatter block active, which means, because of frequent message changes, the
chatter block was set.
• O Output block active, which means the command output is de-coupled from the
process (from the system).
• – None of the listed limitations is in effect.
