Default triggering settings are selected depending on theconnected input signal type. Typically all protection START signals are selected totrigger the disturbance recorded by default.3.6.3 Functional diagramsThe functional diagrams describe the default input, output, alarm LED and function-to-function connections. The default connections can be viewed and changed withPCM600 according to the application requirements, if necessary.The analog channels, measurements from current transformers and voltagetransformers, have fixed connections towards the different function blocks insidethe IED’s standard configuration. Exceptions from this rule are the eight analogchannels available for the disturbance recorder function. These channels are freelyselectable and a part of the disturbance recorder’s parameter settings.The analog channels are assigned to different functions. The common signalmarked with 3I represents the three phase currents. The signal marked with Iorepresents the measured residual current, via a sum connection of second CT coresof the phase current transformers.3.6.3.1 Functional diagrams for protectionThe functional diagrams describe the IED’s protection functionality in detail andpicture the factory set default connections.Section 3 1MRS756498 DRED615 standard configurations60 RED615Application Manual
