Dosing control configuration
Dosing control includes valve control (discrete/analog) and fault handling. The valve control is
done using channels 2, 3 and 4. Dosing control can be configured to:
● One on/off valve
● Two on/off valves
● Control valve
One on/off valve
Use one Signal or one Relay output to control the one-stage dosing. Set the Operating Mode
of signal output to Status. Assign Status Mode to control the Primary Valve. A Signal Input can
be assigned to start the dosing.
Two on/off valves
Use two Signal or two Relay outputs to control the two-stage dosing. Set the Operating Mode
of signal output to Status. Assign one Status Mode to control the Primary Valve and the other
to control the Secondary Valve. A Signal Input can be assigned to start the dosing.
Control valve
Use one Signal output to control the Control valve. Assign the Operating Mode to Current
Output. A Signal Input can be assigned to start the dosing.
Process Values
The following process values can be used for dosing control:
● Mass flow
● Volume flow
