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).
