Depending on what the external recloser device requires, the three single-pole outputs
(F.No
512, 513, 514) may also be combined to one “single-pole tripping” output; the
F.No
515 provides the “three-pole tripping” signal to the external device.
If only three-pole reclosure takes place, general starting (F.No
501,ifrequiredbythe
external reclosure device) and the trip signals (F.No
511) from 7SA6 (see figure 6-
107) usually suffice.
