Matrix Engineering provided electrical engineering necessary to design, specify as well as build and install a control system for an electro-static painting process. This system consisted of an Allen Bradley PLC, linear positioner, and AC & DC variable speed drives. The variable speed drives controlled the speed of the main overhead conveyor throughout the plant. We design the system so that the operators could easily change the paint system using the linear positioner to accommodate varying cylinder sizes. Matrix also performed intensive start-up and checkout, and operator training.
