Figure. 5.4.1 - 82. Setting group control – one-wire connection from Petersen coil status.
Depending on the application's requirements, the setting group control can be applied either with a
one-wire connection or with a two-wire connection by monitoring the state of the Petersen coil
connection.
When the connection is done with one wire, the setting group change logic can be applied as shown in
the figure above. The status of the Petersen coil controls whether Setting group 1 is active. If the coil is
disconnected, Setting group 2 is active. This way, if the wire is broken for some reason, the setting
group is always controlled to SG2.
