Other back-up functions are connected to the input TRINP_3P as described above for
three-pole tripping. A typical connection for a single-pole tripping scheme is shown in
figure 200.

Single-, two- or three-pole tripping

The single-/two-/three-pole tripping mode provides single-pole tripping for single-
phase faults, two-pole tripping for two-phase faults and three-pole tripping for three-
phase faults. The operating mode is always used together with an autoreclosing scheme
with setting ARMode = 1/2/3 ph or ARMode = 1/2 Ph.
The functionality is very similar to the single-phase scheme described above. However,
in addition to the connections for single phase SMBRREC (79) must also be informed
that the trip is two phases by connecting the output TR2P to the input TR2P in the
SMBRREC (79) function.
