AU_OPEN and AU_CLOSE are used to issue automated commands as e.g. for load
shedding for opening respectively closing to the SCSWI function. They work
without regard to how the operator place selector, PSTO, is set. In order to have
effect on the outputs EXE_OP and EXE_CL, the corresponding enable input,
EN_OPEN respectively EN_CLOSE must be set, and that no interlocking is active.
L_SEL, L_OPEN and L_CLOSE are used for local command sequence connected to
binary inputs. In order to have effect, the operator place selector, PSTO, must be
set to local or to remote with no priority. If the control model used is Select before
operate, Also the corresponding enable input must be set, and no interlocking is
active. The L_SEL input must be set before L_OPEN or L_CLOSE is operated, if the
control model is Select before operate.
If one multi-phase XCBR/XSWI or two single-phase XCBR/XSWI are used for a two-
or three-phase system, two or more of the inputs XPOSL1, XPOSL2 and XPOSL3 are
connected to the same source.
