Operation4-12Part 1604870-05  2018 Nordson CorporationPowder Flow SettingsHD Powder Flow SettingsNOTE: Powder flow control modes can only be adjusted for Venturisystems. Refer to the XT Powder Flow Settings section for more details.Powder flow is controlled by a timing sequence that is stored in a softwarelook-up table. The cycle rate of the pump coupled with the suction duration,controls the number of pulses as well as the size of each pulse of powder.Each setpoint from 1−100 has its own recipe for pump operation. As youchange the powder flow set point, these parameters change to increase ordecrease the mass powder flow. Unlike the venturi technology, the powdermass flow is not affected by the pattern air setting. The pattern air willchange the delivery velocity as the powder exits the gun as well as changethe atomization of the powder cloud. Powder flow output from 0−100% Pattern air from 0.20−4.00 cfm in 0.05 incrementsSetting Powder Flow SetpointsTo set flow or pattern air:1. Press the Flow or Pattern button. The green LED on the selectedbutton lights up.2. Turn the Rotary Knob to increase or decrease the setpoints. Thesetpoint is automatically saved if it does not change for 3 seconds orwhen any button is pressed.Flow or Pattern Setpoint Display: When the spray gun is not triggered the setpoints are displayed. When the spray gun is triggered the actual flows are displayed.Flow ButtonPattern IconFlow IconPattern ButtonFigure 4-10 Flow or Pattern SetpointsNOTE: Increasing pattern air will not increase powder flow output.
