Example: dSt for hysteresis function
1 Volumetric flow quantity Q reaches 0�5% of VMR → dSt starts, output becomes active�
2 dSt elapsed, Q reached SP → output remains active�
3 Q below SP, but above rP → output remains active�
4 Q below rP → output is reset�
5 Q reaches again 0�5 % of VMR → dSt starts, output becomes active�
6 dSt elapsed, Q has not reached SP → output is reset�
7 Q reaches SP → output becomes active�
