 -switching signal for temperature limit

 -switching signal for pressure limit

 -switching signal for preset counter

 -switching signal for quantity meter

 -analogue signal for volumetric flow quantity

 -analogue signal for temperature

 -analogue signal for pressure

 -input for external counter reset signal (InD)

 -OFF (output switched to high impedance)

4.2  Switching output

OUTx changes its switching status if it is above or below the set switching limits 

(flow, temperature or pressure)� Hysteresis or window function can be selected� 
Example of volumetric flow monitoring:

Hysteresis function

Window function

SP

rP

FL

FH

SP = set point

rP = reset point

HY = hysteresis

Hno / Fno = NO (normally open)

FH = upper limit 

FL = lower limit 

FE = window

Hnc / Fnc = 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 is changed automatically; the difference remains 

constant�
