Figure 306: Disconnect scheme logic, sheet 4 of 4

The disconnect control element contains the auxiliary logic for control of circuit breakers

required for SCADA and the front panel interface. The control function incorporates select-

before-operate functionality. Selection is required before a control action is permitted.

Selecting a device inhibits service to other clients. Selection is also inhibited if an operation

is in-progress. The logic permits interlocking to be bypassed if required.

Select the Settings > Automation > Disconnects > Disconnect Control menu item to
