For the tripping signals (table 2-13) the stage which caused the tripping is also output. If the device has the
option to trip single-pole, and if this option has been activated, the pole which has been tripped is also indicated
(refer also to Section 2.25.1„Tripping Logic of the Entire Device“).
Table 2-13 Trip signals of the indvidual phases
1)
If tripping by the 3I0 measuring unit is performed simultaneously with or after tripping by a phase measuring
unit and if 1-pole tripping is active, „O/C TRIP 1p.L1“, „O/C TRIP 1p.L2“ or „O/C TRIP 1p.L3“ is signalled.
2)
If tripping is only performed by the 3I0 measuring unit but not by a phase measuring unit, „O/C TRIP L123“
is signalled.
