subject: Distributed control system for powder coating system [print this page] The present invention relates to two areas of powder coating spray control. First is the selection and control of certain spray parameters, for example, the powder flow air pressure, the atomizing air pressure and pattern air pressure, if required. In addition, with corona type spray guns, an electrostatic voltage is selected and supplied by an internal power supply. The second area of powder spray control is gun triggering, that is, when the spray gun is turned ON and OFF, in relation to parts traveling through the spray booth. In the most basic systems, the air pressures and electrostatic voltage are controlled by manually setting respective pressure regulators and a power supply, and the gun triggering is also manually controlled.
