Configuring the Filling and Dosing Application

To configure Channel A as a three-level output, use the Analog Output panel and:

-Set Primary Variable to Primary Valve.

-Ensure that Enable 3 Position Valve is enabled.

-Specify the Setpoint, which is the mA output level that sets the valve to closed partial.

-Specify the Closed Value, which is the mA output level that sets the valve to closed full. This value must be between 0 and 4 mA, and should be set according to the requirements of the valve.
