Functional diagrams
The functional diagrams describe the default input, output, alarm LED and function-
to-function connections. The default connections can be viewed and changed with
PCM600 according to the application requirements.
The analog channels have fixed connections to the different function blocks inside
the merging unit’s application configuration. However, the 12 analog channels
available for the disturbance recorder function are freely selectable as a part of
the disturbance recorder’s parameter settings.
Phase currents are fed to the merging unit from a current transformer or a current
sensor depending on the order options. Residual current is fed to the merging unit
either from residually connected CTs, an external core balance CT or neutral CT.
Phase voltages are fed to the merging unit from a voltage transformer or a voltage
sensor depending on the order options.
