11.3.1.5 Logic diagram
M15086-3 v6
The function contains logic to enable the open and close commands respectively if
the interlocking conditions are fulfilled. That means also, if the switch has a
defined end position for example, open, then the appropriate enable signal (in this
case EN_OPEN) is false. The enable signals EN_OPEN and EN_CLOSE can be
true at the same time only in the intermediate and bad position state and if they are
enabled by the interlocking function. The position inputs come from the logical
nodes Circuit breaker/Circuit switch (SXCBR/SXSWI) and the enable signals
come from the interlocking logic. The outputs are connected to the logical node
Switch controller (SCSWI). One instance per switching device is needed.
