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
IED's standard 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.
The phase currents to the IED are fed from Rogowski or Combi sensors. The residual
current to the IED is fed from either residually connected CTs, an external core
balance CT, neutral CT or internally calculated.
The phase voltages to the IED are fed from Combi sensors. The residual voltage is
internally calculated.
The IED offers six different settings groups which can be set based on individual
needs. Each group can be activated or deactivated using the setting group settings
available in the IED.
Depending on the communication protocol the required function block needs to be
instantiated in the configuration.
Functional diagrams for protection
The functional diagrams describe the protection functionality of the IEDs in detail and
according to the factory set default connections.
