The purpose of this job was to perform the conceptual design, PLC and HMI software design, control panel build, mechanical subcontractor management, and commissioning for the fuel blend system at an automotive research facility.The Fuel Blending System contained two boards of 374 manually actuated valves. Each board (labeled “J” and “K”) contained 22 valves across by 17 valves high for a total of 748 valves. The valve boards supplied various fuel types to test cells in the research facility’s campus. Due to the types of fuel being used, the operational environment was treated as Class 1 Division 1.The objective was to design and implement a control system to operate and monitor all of the manually actuated valves in this environment, as well as all automated valves in the fuel supply system.
The purpose of this project was to provide the electrical process controls upgrade for an existing automotive paint facility. New global controls architecture was used wherever possible. A combination of standard panels and custom designed panels were engineered while utilizing the new controls architecture. New MCPs and VFDs were purchased. Existing control panels were re-used. All I/O was removed and replaced by Allen Bradley Flex I/O with DeviceNet communication. New ControlLogix PLC programs and Siemens WinCC HMI programs were created for all systems.The Carrier Cleaner system upgrade included a control-reliable design and a new DeviceNet interface with two relocated and reused robots.
