AnIn1 Function Max [5136]
With AnIn1 Function Max the physical maximum value is
scaled to selected process unit. The default scaling is
dependent of the selected function of AnIn1 [511]. See table
35.
AnIn1 Function Value Max [5137]
With AnIn1 Function VaMax you define a user-defined
value for the signal. Only visible when user-defined is
selected in menu [5136].
Example:
Process sensor is a sensor with the following specification:
Range: 0–3 bar
Output: 2–10 mA
Analogue input should be set up according to:
[512] AnIn1 Setup = User mA
[5131] AnIn1 Min = 2 mA
[5132] AnIn1 Max = 10 mA
[5134] AnIn1 Function Min = User-defined
[5135] AnIn1 VaMin = 0.000 bar
[5136] AnIn 1 Function Max = User-defined
[5137] AnIn1 VaMax = 3.000 bar
AnIn1 Operation [5138]
AnIn1 Filter [5139]
If the input signal is unstable (e.g. fluctuation reference
value), the filter can be used to stabilize the signal. A change
of the input signal will reach 63% on AnIn1 within the set
AnIn1 Filter time. After 5 times the set time, AnIn1 will
have reached 100% of the input change. See fig. 134.

5137 AnIn1 VaMax
Default: 0.000
Range: -10000.000 – 10000.000
NOTE: With AnIn Min, AnIn Max, AnIn Function Min
and AnIn Function Max settings, loss of feedback
signals (e.g. voltage drop due to long sensor wiring)
can be compensated to ensure an accurate process
control.
