Fig. 42: Phase-selective General Trip signals and the respective collective signals.
(*)
All trip signals, including the phase-selective ones, are issued only by protection functions
that are set as »De󰅰nition« = “Trip”. (See also ╚═▷ “De󰊟nition (“Alarm ↔ Trip”) of a
Protection Function”.) This is not shown explicitly in the diagram.
(**) A second »ExP« instance is available only on WIC1 variants with two Digital Inputs. (See
order options.)
