4.3.2: AO Select (F = Level)
Assignment of a measured value to the analog output
Value
Here you can set whether the analog output supplies the level, volume, or mass to the
control system.
The value of Parameter 4.3.3 is determined by the selection (Level, Volume or
Note:
Mass) in Parameter 4.3.2 (AO select).
If 4.3.2 (AO Select) = Level
4.3.3: Level Parameter (= Parameter 4.2.4)
If 4.3.2 (AO Select) = Volume
4.3.3: Volume Parameter (= Parameter 4.2.5)
If 4.3.2 (AO Select) = Mass
4.3.3: Mass Parameter (= Parameter 4.2.6)
4.3.4: Current Limit (F = 20 mA)
Upper current limit
Value
Here you can set the upper current limit of the output signal in steps of 0.1 mA.
Current limiting
The URV is always at 20 mA. If you set the current limit to a higher value, you can have the
measured values output outside the measuring range (up to approx. 115%).
