Duration [s]
Within the time windows A, B, C the output is switched depending on
the flow: output closed (OUT = 1) if flow ≥ SP / output open (OUT = 0) if
flow < SP.
If the flow rises or falls within the time windows A, B, C, the switching status
can change.
In the time windows D, E, F the output is used for feedback signals (→ table
below). It does not react to flow changes.
