4.3: Analog Output
4.3.1: Error Level (F = D: Error Signal)
Level for the error signal to alarm in Analog or Digital output
Value
When D is selected, all errors are displayed. When D+F is selected, there is special
handling for failsafe. When D+F+W is selected, there is special handling for warnings.
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.
Note:
The value of Parameter 4.3.3 is determined by the selection (Level, Volume or
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 (see
Current limiting diagram on next page).
