A powder coating control system comprising a plurality of gun controls associated with a like plurality of powder spray guns. Each of the gun controls stores a plurality of presets spray parameters. Each of the gun controls responds to part identification signals and part position signals to select in real time one of the stored presets of spray parameters and trigger its respective powder spray gun ON and OFF to apply a powder coating to the moving part in accordance with the selected set of spray parameters. The control system further permits a gun purge cycle to be programmed either before or after the powder coating process is executed. The control system automatically initializes and brings each of the gun controls to an operable state on-line with the system control.

Distributed control system for powder coating system

A beam of light is transmitted from a transmitter (30) which is broken as the moving fiber (22) passes through the beam. A receiver (32) receives the light and generates a signal in response thereto. The signal is processed to determine the status of the pattern generated by the moving fiber (22) of material. In response to changes in the status of the pattern, the rate at which the fiber is dispensed and/or the movement of the pattern can be adjusted as well as alarm conditions noted.
