Disconnect interlocking
The disconnect interlocking element contains the auxiliary logic for interlocking of
disconnects. Up to three inputs can be assigned for interlocking the open and close
controls. An input is also available for supervision by a synchrocheck element. The
disconnect can also be tagged through the front panel interface or through SCADA.
Opening and closing of a tagged device is inhibited in logic.
Select the Settings > Automation > Disconnects > Disconnect Interlocking menu to open
the disconnect control configuration window.
