SGR1...SGR8
The start and operate signals of the protection stages are connected to the output
contacts with switches of switchgroups SGR1...SGR8.
The matrix below can be used for help in making the desired selections. The start
and operate signals of the different protection stages 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 on the bottom row of the matrix. The switchgroup checksum is obtained
by adding together horizontally the weighting factors of all the selected switches of
the switchgroup.
