Abstract
A method and apparatus for controlling components used in the application of a coating incorporates digital communications and improved signal verification into the coating process. The method consist of sending data from one or more controllers to a controlled device, such as an electrostatic power supply, turbine speed controller or other coating device, and receiving data therefrom over a digital data link. The data sent to the controlled device may include any control parameters, including activating the controlled device to perform an intended function or instructions that tell the controlled device what to do. The data which may be returned from the controlled device includes various status information. Where the controlled device is a power supply, the method further incorporates a cross-checking function, to prevent accidental activation. The coating apparatus includes a device for spraying a paint, powder, or other type of coating in a controlled manner onto a receiving surface. An array of structures and forms of digital communication are contemplated, but in all cases include a digital communications link between controller and coating apparatus.
