9.3 Setting the output signal
9.3.1 Setting the output function
► Select [OU1] and set the switching function:
-[Hno] = hysteresis function / normally open,
-[Hnc] = hysteresis function / normally closed,
-[Fno] = window function / normally open,
-[Fnc] = window function / normally closed�
► Select [OU2] and set the switching function:
-[Hno] = hysteresis function / normally open,
-[Hnc] = hysteresis function / normally closed,
-[Fno] = window function / normally open,
-[Fnc] = window function / normally closed,
-[I] = current signal proportional to the pressure 4…20 mA,
-[U] = voltage signal proportional to the pressure 0���10 V�
9.3.2 Setting the switching limits
► Select [SP1] / [SP2] and set the value at which the output switches�
► Select [rP1] / [rP2] and set the value at which the output switches back�
rPx is always lower than SPx� The unit only accepts values which are lower
than SPx�
9.3.3 Scaling the analogue value
► Select [ASP] and set measured value at which 4 mA / 0 V are output�
► Select [AEP] and set measured value at which 20 mA / 10 V are output�
Minimum distance between ASP and AEP = 25 % of the final value of the
measuring range (scaling factor 1:4)�
9.4 User settings (optional)
9.4.1 Zero-point calibration
► Select [COF] and set a value between -5% and 5% of the final value of
the measuring range� The internal measured value “0” is shifted by this
amount�
9.4.2 Calibration reset
► Select [CAr]�
► Press [SET] until [---] is displayed�
► Press [Mode/Enter] briefly�
