Part of the starting and tripping signals from
the relay modules are permanently connected
to the output relays, whereas part of the output
signals are routed through switchgroup SGR.
The switchgroup is located at the front edge of
the output relay module. The switches are set
through the opening in the relay system front
panel.

The switchgroups SGB on the PC-boards of the
relay modules SPCU 1C6 and SPCU 3C15 are
used for routing incoming external blocking sig-
nals to the protection stages to be blocked.
The functions of the switchgroups SGB and
SGR are described in the tables as follows:
