The switches of the programming switchgroup
SGB on the PC boards of the overcurrent and
earth-fault modules are used for linking the
starting signals of the relay modules to the
starting inputs of the auto-reclose module. The
SGB switches are also used for connecting the
incoming blocking signals to the protection.
Switch Function
SGB/1 Links the starting signal of stage I> to the starting input AR2 of the
auto-reclose module. (generally the starting input of AR initiated by
the low-set overcurrent stage)
SGB/2 Links the starting signal of stage I>> to the starting input AR2 of the
auto-reclose module
SGB/3 Links the starting signal of stage I>> to the starting input AR1 of the
auto-reclose function. (generally the starting input of AR initiated by
the high-set overcurrent stage)
SGB/4 Forms from the blocking input signal BS1 a blocking signal for the
tripping of stage I>
SGB/5 Forms from the blocking input signal BS1 a blocking signal for the
tripping of stage I>>
SGB/6 Forms from the blocking input signal BS2 a blocking signal for the
tripping of stage I>
SGB/7 Forms from the blocking input signal BS2 a blocking signal for the
tripping of stage I>>
