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 matrix tool of PCM600 can be used for modifying the interlocking
scheme to suit your application.
