The ProFix has four target settings that it can regulate based on: flap completely closed, Vmin (minimum target airflow), Vmax (maximum target airflow), and flap completely open. The current target airflow can be communicated via a 0-10V signal based on the machine process.
For example, a minimum target airflow can be achieved during machining operation when the doors of the machine tool are closed and well sealed but the machine tool can communicate the end-of-cycle and adjust the ProFix back to the maximum target airflow when the machine doors are open.
