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 a current transformer. The residual current
to the IED is fed from either residually connected CTs, an external core balance CT,
neutral CT or internally calculated.
The residual voltage to the IED is fed from either the residually connected VTs or an
open delta connected VT.
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.
