Operation5-16Part 1614575-01 2019 Nordson CorporationVT Powder Flow Settings (contd)Classic Flow Mode SettingsIn Classic Flow mode, flow air and atomizing air ranges are: Flow air from 0−5.95 M 3/HR (0−3.5 SCFM in 0.05 increments). Atomizing air from 0−5.95 M 3/HR (0−3.5 SCFM in 0.05 increments).To set flow or atomizing air:1. Press the Flow or Atomizing button. The green LED on the selectedbutton lights.2. Turn the Rotary Knob to increase or decrease the setpoints.3. Once the value is chosen the user can either: wait 3 seconds and the value will save for the current jobOR press Enter to also save the new value to the current preset. When the spray gun is not triggered the setpoints are displayed. When the spray gun is triggered the actual flows are displayed.FlowAtomizingFigure 5-9 Classic Mode − Flow Air or Atomizing Air Flow SetpointsSmart Flow ModeIn Smart Flow mode, Total Flow ∑ sets the velocity of the powder flow, whileFlow Air % sets the powder flow rate. Powder velocity is inversely related totransfer efficiency; the higher the velocity, the lower the transfer efficiency.When making Smart Flow settings, set the Total Flow ∑ setpoint first toobtain the desired pattern size and penetration, then set the Flow Air %setpoint for the desired powder flow.Flow Air %: 0−100%. The actual percentage range available variesdepending on the total air setpoint and the maximum and minimum outputsfor flow and atomizing air.Total Flow : 2.55−10.2 M3/HR, minimum 0.17 M3/HR increments, or1.5−6.0 SCFM, minimum 0.1 SCFM increments.
