After the start of the start-up delay there are 3 options:
1� The volumetric flow increases quickly and reaches the set point / good range
within dST�
> Outputs remain active�
2� The volumetric flow increases slowly and does not reach the set point /good
range within dST�
> Outputs are reset�
3� Volumetric flow quantity falls below 0�5 % within dST�
> Outputs are reset at once; dST is stopped�
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�
