Valve control configuration

Valve control dosing
Dosing is controlled with either one or two discrete valves or a single analog valve. The
transmitter provides up to three input/output channels which can be used for dosing control.
The selection of channels is fixed when ordering the system. The channels can be setup for
dosing functionality in parameter 2.5.1 "Dosing Mode" as shown in the table below. Allocation
of the output to a specific dosing sequence element is performed in the software configuration
as follows:
One on/off valve
