HY = hysteresis; FE = window; examples for volumetric flow monitoring
When set to the window function the set and reset points have a fixed hysteresis of 0�25 %
of the final value of the measuring range� This keeps the switching state of the output stable
if the volumetric flow varies slightly�
4.6 Volumetric flow or temperature monitoring / analogue
function
•
The analogue start point [ASP] determines at which measured value the output
signal is 4 mA or 0 V�
•
The analogue end point [AEP] determines at which measured value the output
signal is 20 mA or 10 V�
•
Minimum distance between [ASP] and [AEP] = 20 % of the final value of the
measuring range�
