Eaton E Series - Switchgear Configuration 2

The trip command becomes active, in the sense that it triggers a Relay Output. This is
absolutely essential is any protection function shall open a Breaker.
Remark: For information about trip commands, see also ╚═▷ “Trip Commands”. For
information about binary outputs, see also ╚═▷ “5.2.4 Relay Outputs (Binary Outputs)”.
For detailed information about anything, see the Technical Manual.
5.2.11 Switchgear Con󰈛guration 2
The single-line diagram (see ╚═▷ “3.9 “CTRL” key – Control Switchgear Devices”, ╚═▷ “Trip
Commands”, ╚═▷ “3.12 Single-Line Diagram”) shows the switchgear devices and their
positions in a graphical manner: Any change of the position is re󰊠ected by a change of the
corresponding symbol of the switchgear. This, however, is only possible if the position of
each switchgear is reported to the protection device by means of an auxiliary contact. The
protection device has to “know” which digital input (╚═▷ “5.2.3 Digital Inputs”) is related to
which switchgear device.
Note that the designation of every switchgear device is also de󰊟ned in the single-line,
see ╚═▷ “3.12 Single-Line Diagram”. Not only does the graphical representation depend
on this setting, but also all the menu items related to the switchgear are renamed
accordingly.
This means that instead of the 󰊟rmware-based menu items [Bkr[1]], [Bkr[2]], … the
protection device shows the switchgear names from the single-line, e. g. [QA1], [QA2], …
For the examples throughout this document, we use something like “Qxx” as the
switchgear name.
[1.] Hardware (wiring) work:
At 󰊟rst the switchgear positioning indicators have to be connected to the digital inputs of the
protection device.
For detection of their positions all switchgear devices feature Aux contacts (“Aux ON” and
“Aux OFF”).
In any case, the “Aux ON” must be wired.
The “Aux OFF” contact is strongly recommended to be wired, too, because otherwise, it
would not be possible to detect intermediate and disturbed positions.
This results in an assignment of position indicators to the connected digital inputs, which is
then con󰊟gured in the settings of the protection device.
[2.] Con󰃰guration work:
For every switchgear device “Qx”, enter the menu branch [Control / Bkr / Qx / Pos
Indicatrs Wirng] and set the parameters »CinBkr-52a« and »CinBkr-52b« to the connected
digital inputs.
(Remark: The designations “Qx” depend on the settings that you have made in the single-
line, see ╚═▷ “3.12 Single-Line Diagram”.)
