ABSTRACT:
An apparatus for controlling a color change sequence of automatic paint spray equipment. The apparatus controls the performance of various cleaning functions when it is desired to convert the spray equipment from spraying one color of paint to spraying of another color of paint. The apparatus includes a fluid motor coupled through a reducing transmission to a drum-type programmer. The drum-type programmer includes a set of program sections, each section being divided into a plurality of sectors and each sector adapted to receive a cam plug. Each section is programmed by inserting cam plugs in selected sectors thereof. Fluid switches are mounted adjacent the drum programmer, at least one switch being associated with each of the sections of the drum programmer and responsive to the presence and absence of cam plugs from various ones of the sectors in its respective section of the drum programmer to control a color change function.
