4  Function

4.1  Processing of the measured signals

The unit converts the system pressure into an analogue output signal (4...20 mA).

The measuring range can be scaled to up to 25% of the finalvalue of the measur-

ing range.

•  By setting the parameter ASP you define the measured value at which the 

output signal is 4 mA.

•  By setting the parameter AEP you define the measured value at which the 

output signal is 20 mA.

Factory setting

Measuring range scaled

P = system pressure, MEW = final value of the measuring range

The output signal is between 4 and 20 mA. It is also indicated:

•  System pressure above the measuring range: output signal > 20 mA .

•  System pressure below the measuring range: output signal between 4 and 3.2 mA.
The unit is ready for operation when delivered. Factory preset: not scaled (ASP = 

0 bar; AEP = 100% of the final value of the measuring range).
