Switch
Function
SGR3/1 Routes the start signal of stage I> to TS1
SGR3/2 Routes the operate signal of stage I> to TS1
SGR3/3 Routes the start signal of stage I>> to TS1
SGR3/4 Routes the operate signal of stage I>> to TS1
SGR3/5 Routes the start signal of stage I
SGR3/6 Routes the operate signal of stage I
SGR3/7 Routes the start signal of stage I
SGR3/8 Routes the operate signal of stage I
Checksum for the default settings of switchgroup SGR3
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.
Switch
Function
SGB/1
Routes the starting signal of stage Iϕ> to the starting input
AR3 of the auto-reclose module (generally the starting input
of AR initiated by the low-set earth-fault stage)
SGB/2
Routes the starting signal of stage Iϕ>> to the starting input
AR3 of the auto-reclose module
SGB/3
Routes the starting signal of stage Iϕ>> to the starting input
AR1 of the auto-reclose module
SGB/4
Forms from the blocking input signal BS1 a blocking signal
for the operation of stage Iϕ>
SGB/5
Forms from the blocking input signal BS1 a blocking signal
for the tripping of stage Iϕ>>
SGB/6
Forms from the blocking input signal BS2 a blocking signal
for the tripping of stage Iϕ>
SGB/7
Forms from the blocking input signal BS2 a blocking signal
for the tripping of stage Iϕ>>
SGB/8
No function in SPAC 536/636 C. Has to be in position 0
Note!
Only one of the switches SGB/2 and SGB/3 is
allowed to be in position 1 at a time.

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.
