4.5 Switching function

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

(flow or temperature)� Hysteresis or window function can be selected� Example of

volumetric flow monitoring:

Hysteresis function

Window function

SP

rP

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 is changed automatically; the difference

remains constant�
When set to the window function, the upper limit [SP] and the lower limit

[rP] have a fixed hysteresis of 0�25 % of the final value of the measuring

range� This keeps the switching status of the output stable if the flow rate

varies slightly�
