Switch Function
SGB1...5/4 Switching between setting groups 1 and 2 using the digital input
• 0 = the setting group cannot be changed using the digital input
• 1 = the setting group is changed by using the digital input.
When the digital input is energized, setting group 2 will be
activated, if not, setting group 1 will be activated.
Note!
When SGB1...5/4 is set to 1, it is important that the switch has
the same setting in both setting groups.
SGB1...5/5 Time synchronization by the digital input signal
SGB1...5/6 External tripping by the digital input signal
SGB1...5/7 External triggering of the CBFP by the digital input signal

SGR1...SGR8
The start, trip and alarm signals from the protection stages, the signals from the
auto-reclose function, and the external trip signal are routed to the output contacts
with the switches of switchgroups SGR1...SGR8. The signals are routed to
PO1...PO3 with the switches of switchgroup SGR1...SGR3 and to SO1...SO5 with
those of SGR4...SGR8.
The matrix below can be of help when making the desired selections. The start, trip
and alarm signals from the protection stages, the signals from the auto-reclose
function and the external trip signal are combined with the output contacts by
encircling the desired intersection point. Each intersection point is marked with a
switch number, and the corresponding weighting factor of the switch is shown to the
right in the matrix. The switchgroup checksum is obtained by vertically adding the
weighting factors of all the selected switches of the switchgroup.
Note!
The trip lockout signal is always routed to PO3.
Note!
The trip signal from CBFP is always routed to PO2.
