Additionally, all the digital inputs that are connected by default are also enabled with
the setting. Default triggering settings are selected depending on the connected input
signal type. Typically all protection START signals are selected to trigger the
disturbance recorded by default.

Functional diagrams
The functional diagrams describe the default input, output, programmable LED,
switch group and function-to-function connections. The default connections can be
viewed and changed with switch groups in PCM600, LHMI and WHMI according to
the application requirements.
The analog channels have fixed connections towards the different function blocks
inside the protection relay’s configuration. Exceptions from this rule are the four
analog channels available for the disturbance recorder function. These channels are
freely selectable and a part of the disturbance recorder’s parameter settings.

Functional diagrams for protection
The functional diagrams describe the protection functionality of the protection relay
in detail and picture the factory default connections.
