• Installation and Configuration of Foxboro I/A System

  In a recent project at a large paper mill, MAVERICK was responsible for the installation and configuration of the Foxboro I/A system interfaced with a GE Mark V turbine control system. During initial stages of the project, MAVERICK laid out the Foxboro I/A cards and supervised the building of the control cabinet. The cabinet and operating system were shipped to MAVERICK for configuration, and a Mark V simulator was used for configuration purposes. A communication system between the two systems was set up to allow an easier checkout. MAVERICK was also responsible for a cooling water control system, which was configured to utilize the Foxboro I/A, as well. This allowed the Foxboro to not only be a monitor and control for the new turbine, but also for the two cooling towers. Mill representatives visited MAVERICK facilities and performed a thorough checkout, ensuring a smooth startup. After completion of startup, MAVERICK created a performance test data collector by interfacing Microsoft Excel with Foxboro I/A using data for Windows. This provided initial performance data for the new turbine generator system.

• Major Controls Retrofit

  MAVERICK has completed a major controls retrofit for a large paper mill. In a series of consecutive projects, MAVERICK completed conversion to Foxboro I/A / A-B PLC, the Nos. 21, 22, 23 and 24 coated paper machines. The project included ABB paper machine controls through the Foxboro I/A Series 50 DCS with redundant control processors. The new distributed control system interfaced to existing Allen-Bradley Series 5 and GE Series 70 PLCs, with an approximate point count of 600 analog and 550 discrete. The new control system included the size presses, coating kitchen, and stock and broke systems.

• Upgrades to Rapid Drain and Black Liquor Diversion Control Systems

  MAVERICK completed an engineering project to upgrade the rapid drain and black liquor diversion control systems on three recovery boilers. A two-step ESP system was implemented as part of the design. The new control system employed Allen-Bradley PLC-5/25, Wonderware MMI, 8 graphics and 130 I/O points, and monitored operation of the recovery boilers during emergency shutdown procedure and rapid drain.

• Groundwood Mill Retrofit for a Paper Company
  This project involved an Allen-Bradley PLC 5/80 connected to 900 field I/Os, an Allen-Bradley coprocessor running a custom C program and seven networked Wonderware nodes on Ethernet. The controls consisted of 70 PID loops using PLC functions (many cascaded) and 120 Wonderware graphics. The script was embedded within graphics to allow modification of the rate and load grinding algorithms. A custom Modbus interface was also created to the Westinghouse WDPF highway via a PC for operation and performance monitoring of the groundwood mill and power generators. Finally, the control system for the mill wastewater treatment plant incorporated an Allen-Bradley PLC 5/40 with 350 field I/Os and five networked Wonderware nodes with 30 graphics.
