• Window function / normally open (fig� 2): [OUx] = [Fno]�
• Window function / normally closed (fig� 2): [OUx] = [Fnc]�
The width of the window can be set by means of the distance between SPx and
rPx� SPx = maximum value, rPx = minimum value�

HY = hysteresis; FE = window
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 monitoring / analogue function
• The analogue start point [ASP] determines at which measured value the output
signal is 4 mA�
• The analogue end point [AEP] determines at which measured value the output
signal is 20 mA�
Minimum distance between [ASP] and [AEP] = 25 % of the final value of the
measuring range�
