Switchgear Configuration
Wiring
At first the switchgear positioning indicators have to be connected to the digital inputs of the protection device.
One of the position indicators (either the »Aux CLOSE
« or the »Aux OPEN«) contact has to be connected necessarily.
It is recommended also to connect the »Aux OPEN
« contact.
Thereafter the command outputs (relay outputs) have to be connected with the switchgear.
Please observe the following option: In the general settings of a breaker, the
CLOSE/OPEN 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 switchgear position indications are shown in the devices display. Each position change of a switchgear
results in a change of the corresponding 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/SG/SG [x] ] the assignments for the position indications have to be set.
Detection of switchgear position with two Aux contacts – Aux CLOSE and Aux OPEN (recommended!)
For detection of their positions switchgear are provided with Aux contacts (Aux CLOSE and Aux OPEN). It is
recommended to use both contacts to detect intermediate and disturbed positions too.
The protection device continuously supervises the status of the inputs
»Aux CLOSE-I« and »Aux OPEN-I«.
These signals are validated based on the supervision timers »
t-Move CLOSE« and »t-Move OPEN« validation
functions. As a result, the switchgear position will be detected by the following signals:
Pos CLOSE
Pos OPEN
Pos Indeterm
Pos Disturb.
Pos (State=0,1,.2 or 3)
