Operation 4-5Part 1602221-01 2012 Nordson CorporationSmart Flow Mode Settingssets the powder flow rate (Flow Air %).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 thefaster the units change.When making Smart Flow settings, set the Total Flow setpoint first to obtainthe desired pattern size and velocity, then set the Flow Air % setpoint for thedesired powder flow.At 7 bar (100 psi) supply pressure:Total FlowSetting %Flow AirSetting %Flow Air Pressurebar (psi)Atomizing Air Pressurebar (psi)50 50 1.7 (25) 1.7 (25)50 25 0.86 (12.5) 2.6 (37.5)In other words,If Total Flow = 50%, Flow Air = 50%, thenFlow air = 1.7 bar (25 psi) or 1/2 of 3.4 bar (50 psi), andAtomizing air = 1.7 bar (25 psi) or 1/2 of 3.4 bar (50 psi).If Total Flow = 50%, Flow Air = 25%, thenFlow air = 0.86 bar (12.5) psi or 1/4 of 3.4 bar (50 psi), andAtomizing air = 2.6 bar (37.5 psi) or 3/4 of 3.4 bar (50 psi).NOTE: If either Total Flow or Flow Air % are set to 0% then the controllerwill not output any air when triggered and no powder will be pumped.Powder velocity is inversely related to transfer efficiency; the higher thevelocity the lower the transfer efficiency. High powder flow rates can resultin faster wear of powder contact parts.Classic Flow Mode SettingsTo use Classic Flow mode, the controller must be configured for it. Refer topage 3-8 for a list of the mode defaults and configuration instructions.sets the flow air pressuresets the atomizing air pressure.Setting values for both are 0−99% of maximum air pressure.
