ABB Relion 670 series - Logic diagram; Function block; Input and output signals

12.4.3.2 Logic diagram
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.
