L_OPEN or L_CLOSE is operated, if the control model is Select
before operate.
If one multi-phase XCBR or two single-phase XCBR is used for a
two- or three-phase system, two or more of the inputs XPOSL1,
XPOSL2 and XPOSL3 are connected to the same source.

12.4.6.5 Operation principle
M13484-4 v4
The Switch controller (SCSWI) is provided with verification checks for the select -
execute sequence, that is, checks the conditions prior each step of the operation are
fulfilled. The involved functions for these condition verifications are interlocking,
reservation, blockings and synchrocheck.
Control handling
M13484-6 v7
.
Two types of control models can be used. The two control models are "direct with
normal security" and "SBO (Select-Before-Operate) with enhanced security". The
