Hysteresis function

Window function


FL

FH

SP = set point

rP = reset point

HY = hysteresis

Hno / Fno = NO (normally open)

FH = upper limit value

FL = lower limit value

FE = window

Hnc / Fnc = NC (normally closed)

When the hysteresis function is set, the set point (SPx) is defined first and 

then the reset point (rPx) which must be of a lower value� If only the set 

point is changed, the reset point remains constant�
When set to the window function the set and reset points have a fixed hys-

teresis of 0�25 % of the final value of the measuring range� This keeps the 

switching status of the output stable if the volumetric flow varies slightly�

4.2  Analogue function

The unit provides an analogue current signal that is proportional to the volumetric 

flow quantity and the medium temperature� Within the measuring range the output 

signal is between 4 and 20 mA� Outside the measured and displayed value range 

or in case of a fault the signals < 4 mA or > 20 mA are provided  (→ Figures).

Caption:

1:  Output current in mA

2: 

Volumetric flow quantity (final value of the measuring range MEW = 100 %)

3:  Medium temperature

4:  Measuring range

5:  Display range

6:  The unit is in the error state (FOU = OFF)

7:  The process value transmitted in an analogue way is therefore above the display range

8:  The unit is in the error state (FOU = ON)
