SGR1...SGR8
The pickup, trip and alarm signals from the protection elements, 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 pickup,
trip and alarm signals from the protection elements, 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 CBFAIL is always routed to PO2.
Note!
The external fault warning is always routed to SO2.
