4.8 Measured value damping (dAP)
The damping time enables to set after how many seconds the output signal has
reached 63 % of the final value if the flow value changes suddenly� The set damp-
ing time stabilises the outputs, the display and the process value transfer via the
IO-Link interface� The signals [UL] and [OL]
tion of the damping time�
4.9 Start-up delay (dSt)
The start-up delay dST influences the switching outputs of the volumetric
flow monitoring�
If the start-up delay is active (dST > 0), note: As soon as the volumetric flow quan-
tity exceeds the LFC (LFC = Low flow cut-off
), the following processes are
carried out:
> The start-up delay is activated�
> The outputs switch as programmed:ON for NO function, OFF for NC function�
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 LFC within dST�
> Outputs are reset at once; dST is stopped�
