CB decision logic
(iii)
Figure 2.24-1 shows the decision logic of the PROT_COMMON and outputs the decision state
of the CB: CB-A_CLOSE, CB-B_CLOSE, and others.
For the operation, the user should inject signals of CB states for the following PLC
connection points: 'CB1-A NO CONT', 'CB1-A NC CONT' and others. Note that a common point
is ready for the CB designed to three-phase tripping: CB1-NO CONT' and 'CB1-NC CONT'.
