2 Functions
Figure 2-3
Address 1156 Trip2phFlt determines that the short-circuit protective functions
perform only a single-pole trip in case of isolated two-phase faults (clear of ground),
provided that single-pole tripping is possible and permitted. This allows a single-pole
reclose cycle for this kind of fault. You can specify whether the leading phase (1pole
leading Ø), or the lagging phase (1pole lagging Ø) is tripped. The parameter is
only available in versions with single-pole and three-pole tripping. This parameter can
only be altered using DIGSI at Additional Settings. If this possibility is to be used,
you have to bear in mind that the phase selection should be the same throughout the
entire network and that it must be the same at all ends of one line. More information
on the functions is also contained in Section 2.16.1 Pickup Logic of the Entire Device.
The presetting 3pole is usually used.

Addresses which have an appended "A" can only be changed with DIGSI, under Ad-
ditional Settings.
The table indicates region-specific presettings. Column C (configuration) indicates the
corresponding secondary nominal current of the current transformer.
