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.
