1) Basic interlocking functionality: Closing of the circuit breaker can be enabled by a binary input signal. The actual
interlocking scheme is implemented outside the IED. The binary input serves as a “master interlocking input”
and when energized it will enable circuit breaker closing.
2) Extended interlocking functionality: The circuit breaker interlocking scheme is implemented in the IED
configuration, based on primary equipment position information (via binary inputs) and the logical functions
available. The signal matrrix tool of PCM600 can be used for modifying the interlocking scheme to suit your
application.
