Switchgear/Breaker – Manager
Single Line Diagram
The user can create and modify Single Lines (pages) by means of the Page Editor.
The Single Lines (Control Pages) have to be loaded into the protective device by means of Smart view.
For details on the creation, modification and upload of Single Lines (Control Pages) please refer to the manual
“page_editor_uk.pdf” or contact the technical support. The manual can be accessed via the
Page Editor help menu.
The single line diagram includes the graphically description of the switchgear and its designation (name) as well as
its features (short circuit proof or not ...). For displaying in the devices software, the switchgears' designations (e. g.
QA1, QA2, instead of SG[x]) will be taken from the single line diagram (configuration file).
The configuration file includes the single line diagram and the switchgear properties. Switchgear properties and
single line diagram are coupled via the configuration file.
Switchgear Configuration
Wiring
At first the switchgears' positioning indicators have to be connected to the digital inputs of the protection device.
One of the position indicators (either the »Aux ON « or the »Aux OFF«) contact has to be connected necessarily. It
is recommended to connect both contacts.
Thereafter the command outputs (relay outputs) have to be connected with the switchgear.
Please observe the following option: In the general settings of a circuit breaker, the
ON/OFF commands of a protection element can be issued to the same output relays,
where the other control commands are issued.
If the commands are issued to different relays output relays the amount of wiring
increases.
Assignment of Position Indications
The position indication is needed by the device to get (evaluate) the information about the current status /position of
the breaker. The switchgears' position is shown in the devices display. Each position change results in a change of
the switchgear symbol.
For the detection of a switchgear's position always two separate Aux contacts are
recommended! If only one Aux contact is used, no intermediate or disturbed positions
can be detected.
A reduced transition supervision (time between issue of the command and position
feedback indication of the switchgear) is also possible by one Aux contact.
In the menu [Control/Bkr/Pos Indicators wiring] the assignments for the position indications have to be set.
Detection of switchgear position with two Aux contacts – Aux ON and Aux OFF (recommended!)
For detection of position the switchgear is provided with Aux contacts (Aux ON and Aux OFF). It is recommended to
use both contacts to detect intermediate and disturbed positions too.
