SC = Source of command
SC = Auto:
Commands that are derived internally (command processing in the CFC) are not
subject to switching authority and are therefore always "enabled".
S w i t c h i n g M o d e The switching mode determines whether selected interlocking conditions will be acti-
vated or deactivated at the time of the switching operation.
The following switching modes (local) are defined:
• Local commands (SC=LOCAL)
– interlocked (normal), or
– non-interlocked (de-interlocked) switching.
For the 7UM61 the switching authority can be changed between "Interlocked" and
"Non-interlocked" in the operator panel by password or by means of CFC also via
binary input and function key.
The following switching modes (remote) are defined:
• For remote or DIGSI
®
commands (SC = LOCAL, REMOTE, or DIGSI)
– interlocked, or
– non-interlocked switching. Here, deactivation of interlocking is accomplished via
a separate command.
– For commands from CFC (SC = Auto), please observe the notes in the CFC
manual (component: BOOL to command).
Zone Controlled /
Field Interlocking
Zone controlled / field interlockings (e.g. via CFC) includes the verification that prede-
termined switchgear position conditions are satisfied to prevent switching errors (e.g.
disconnector vs. ground switch, ground switch only if no voltage applied) as well as
verification of the state of other mechanical interlocking in the switchgear bay (e.g.
High Voltage compartment doors open against CB closing).
