SGR1...SGR5
The pickup, trip and alarm signals from the protection elements, the motor start-up
signal and the external trip signal are routed to the output contacts with the switches
of switchgroups SGR1...SGR5. The signals are routed to PO1 with the switches of
switchgroup SGR1, to PO2 with those of SGR2, to PO3 with those of SGR3, to
SO1 with those of SGR4 and to SO2 with those of SGR5.
The matrix below can be of help when making the desired selections. The pickup,
trip and alarm signals from the protection elements, the motor start-up signal 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 on the right side of the
matrix, see Fig. 5.1.4.12.-2. The switchgroup checksum is obtained by vertically
adding the weighting factors of all the selected switches of the switchgroup.
If CBFAIL is in use, SGR2 should be set to 0 to avoid conflicts.
If the external fault warning is in use, SGR5 should be set to 0 to avoid
conflicts.
