Pickup logic and tripping logic
The pickup signals of the individual phases (or the ground) and of the stages are linked in such a way that
both the phase information and the stage which has picked up are output (Table 2-3).

For the tripping signals (Table 2-4) 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 indi-
cated in case of single-pole tripping (refer also to Section 2.8.1 Function Control “Tripping Logic of the Entire
Device”).
