Two modes of pump air control are available:
Smart Flow − This is the factory default mode. In this mode, you set Total
Flow and Flow Air %. If you decrease the flow air %, the flow air pressure
decreases, but the atomizing air pressure increases, so that the result is
that the powder velocity remains the same. The Smart Flow LED lights
when the controller is configured for Smart Flow mode.
Classic Flow − This is the traditional method of controlling powder flow and
velocity. In this mode you set flow and atomizing air separately and balance
them manually for optimum results. When the controller is configured for
Classic Flow mode, the Smart Flow LED is off.
NOTE: Refer to page 3-16 for a list of the mode defaults and configuration
instructions.

sets the powder velocity (Total Flow).
Setting values for both are 0 − 99% of maximum output. Press the + and −
buttons to enter the desired setpoint. The longer a button is pressed the
faster the units change.
When making Smart Flow settings, set the Total Flow setpoint first to obtain
the desired pattern size and velocity, then set the Flow Air % setpoint for the
desired powder flow.
