Operation4-14Part 1604870-05  2018 Nordson CorporationSee Tables 4-6 and 4-7 for examples of possible Smart Flow settings andtheir equivalents in Atomizing and Flow Air pressures and flows. Figure4-12 shows the effects of changes in Total Flow and Flow Air % settings.The Smart Flow tables provide a range of possible Total Flow and Flow Air% setpoints. Read across to the vertical axis for the equivalent atomizingair flow and pressure. Read down to the horizontal axis for the equivalentflow-air flow and pressure.The tables show that as you increase Total Flow powder velocity increaseswhile the maximum Flow Air % remains the same. Conversely, for a givenTotal Flow setting, each increase in Flow Air % increases powder flow.Increase flow,no change in velocityMax FlowIncrease velocity,no change in flow50% Flow Air % Setpoint3.00 Total Flow SetpointMax VelocityFigure 4-12 Reading the Smart Flow TablesSetting Smart Flow SetpointsTo set flow air % or total flow ∑ :1. Press the % or  button. The LED on the selected button lights.2. Turn the Rotary Knob to increase or decrease the setpoint. Thesetpoint is automatically saved if it does not change for 3 seconds orwhen any button is pressed.NOTE: If Total Flow is set to zero, the Flow Air % setpoint cannot be set toanything but zero, and powder cannot be sprayed. To set Flow Air %, setTotal Flow to a value greater than zero. When the spray gun is not triggered the setpoints are displayed. When the spray gun is triggered the displays show actual flows.Flow Air %Total Flow Air in M3 /HR or SCFMFigure 4-13 Smart Flow Mode − Flow Air % or Total Flow ∑
