The output signal SS2 is directly connected and
the output signal SS1 via switch SGR/1 con-
nected to the output SIGNAL3. The output
signals TS1 and TS2 are directly connected to
the TRIP output and via switch SGR/2 to the
output SIGNAL1.
The SGB switches on the PC board of the
directional earth-fault module SPCS 3C4 are
used for routing the start signals of the relay
module to the start initiation inputs of the auto-
reclose unit. The SGB switches are also used for
routing the incoming blocking signals to the
protection stages.
Note!
Only one of the switches SGB/2 and SGB/3 is
allowed to be in position 1 at a time.
