SP = set point
rP = reset point
HY = hysteresis
Hno = hysteresis NO (normally open)
Hnc = hysteresis NC (normally closed)
SP = upper limit
rP = lower limit
FE = window
Fno = window NO (normally open)
Fnc = window NC (normally closed)
When the hysteresis function is set, the set point [SP] is defined first and
then the reset point [rP] which must have a lower value� If only the set point
is changed, the reset point remains constant�
5.5 Analogue function
• The unit provides an analogue signal that is proportional to the volumetric flow
quantity and the medium temperature�
• Within the measuring range the analogue signal is 4���20 mA�
• The measuring range is scalable:
[ASP] determines at which measured value the output signal is 4 mA�
[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�
Factory setting
Measuring range scaled
MEW = final value of the measuring range
Volumetric flow above the measuring range: output signal > 20 mA�
Volumetric flow below the measuring range: output signal between 3�6 and 4 mA�
