Ransburg Evolver SE Robotic Atomizer A12455-XXXXXXXX - Manual (Page 20)

AA-09-01.1 : Evolver SE
GENERAL GUIDELINES
Paint Viscosity: The applicator is capable of atomizing paint of most any desired viscosity, however it is recommended
to keep the material viscosity as low as possible. This allows spraying at lower fan and atomization air pressures which
result in less overspray and higher transfer efficiency.
• Most paints and solvents are toxic to a certain degree and flammable or combustible. Use them only
in a well ventilated atmosphere. Use protective equipment as required in the Material Safety Data
Sheet (MSDS) supplied with the substance.
WARNING
Fluid Flow Rate: Fluid flow is adjusted through the robot PLC by varying the pilot pressure to an exterior fluid regulator.
Fluid pressures from the circulating system may exceed the maximum fluid pressure rating of the Evolver SE applicator.
Because of these high fluid pressures, a manual step-down fluid regulator must be used.
Target Distance: The distance between the applicator tip and the article being painted should be 10-14 inches (0.25-
0.36 meters) when using high voltage. Excessive distance will reduce transfer efficiency and cause wrap back (paint
particles being deposited on the applicator body or the robot arm). At close distances the voltage at the tip of the appli-
cator will be reduced, which decreases the charging effect of the applicator.
• If target distance is less than 8 inches (0.20 meters), an arc could occur.
WARNING
Electrostatic Voltage: Under no load conditions, the maximum voltage limit for the Evolver SE applicator is 85 kV.
Some painting operations may require different voltage settings to obtain optimum transfer efficiencies. If Faraday cage
areas (narrow or recessed areas) are predominant on the item being painted, a lower voltage setting would aid in coating
these areas. When not spraying, it is recommended to set back voltage 30-40 kV or OFF between target parts. Some-
times, depending on the target carrier spacing, higher setback voltages may be required.
