Figure 82: Circuit breaker close enable logic
The configuration includes logic for generating circuit breaker external closing and
opening command with the IED in local or remote mode.
Check the logic for the external circuit breaker closing command and
modify it according to the application.
Connect additional signals for opening and closing of circuit breaker
in local or remote mode, if applicable for the configuration.

3.4.3.5 Functional diagrams for measurement functions
The phase current inputs to the IED are measured by the three-phase current
measurement function CMMXU1. The current input is connected to the X120 card in
the back panel. Similarly, sequence current measurement CSMSQI1 measures the
sequence current and the residual current measurement RESCMMXU1 measures the
residual current.
