SGB1...5/4 Switching between setting groups 1 and 2 by using the digital input
0 = the setting group cannot be changed using the digital input

SGR1...SGR8
The start, trip and alarm signals from the protection stages 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 wanted selections. The start, trip
and alarm signals from the protection stages and the external trip signal are
combined with the output contacts by encircling the wanted 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.
