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 system and method of storing and reading parameter data associated with an electrostatic spray gun power supply is provided. The method includes, for example, the steps of reading parameter data associated with a power supply for a particular spray gun from a database and storing the parameter data in a memory device associated with the spray gun. The parameter data may include the drive current parameter information, for example, and additionally, spray gun type identification information. The memory device is preferably integral with the spray gun or a cable connector that connects to the spray gun. The data or information can be in the form of analog or digital information. After reading the spray gun power supply parameter data, the spray gun controller appropriately operates and monitors the spray gun to ensure that the spray gun power supply is performing properly.

Spray gun with data device and method of control

Systems and methods for controlling, organizing, and viewing a plurality of electrostatic spray gun operating parameters from a centralized control panel are provided. In this regard, a control panel is provided having, for example, a gun control area for selecting one electrostatic spray gun of a multiple gun system, and an electrostatic control area for displaying and controlling the operational parameters of the selected electrostatic spray gun. The electrostatic control area functions essentially as a master control panel which can be shared by all the guns in the system. Each of the guns has an assigned gun control subpanel in the gun control area. Each subpanel includes a selector switch which can be used to monitor and control the gun associated with that subpanel on the master control panel. Each of the subpanels also has a limited display such as a bar graph which can be used to show the electrostatic performance of the guns. The subpanel displays are configured in a tight cluster so that the operator can easily simultaneously monitor the performance of all the guns in the system to identify any guns which are not performing properly. A method for mapping a physical arrangement of electrostatic spray guns onto a gun control area of an operator control panel is also provided.
