Plot a diagram similar to the one above – with
values for (I1, F1) and (I2, F2) – so that you can
set the pump as desired!
The smallest processable difference between I1
and I2 is 4 mA (ll I1-I2 ll ≥4 mA).
In the ‘Error message’ menu item, you can activate error pro‐
cessing for these types of processing.
‘Lower side band’
Using this type of processing, you can control a metering pump
using the current signal as shown in the diagram below.
However, you can also control two metering pumps for different
feed chemicals via a current signal (e.g. one acid pump and one
alkali pump using the signal of a pH sensor). To do this, connect
the pumps electrically in series.
In the ‘Error message’ menu item, you can activate error pro‐
cessing for these types of processing.
