GracoPd2kDual API

Add-On Instructions (AOIs)

MainCtrl

Provides several inputs for controlling the PD2K proportioner (e.g. system mode, setpoints).

The enable input must be on for any other inputs to take effect. The boolean command inputs each function like execute inputs, meaning the command will automatically reset these once set to true.

The current control mode setting (pressure or flow) determines which of the setpoint inputs are written to the PD2K system. This switches automatically when the control mode is changed.
