Perkins Engines - Case Study

Case Study: Perkins engine painting Plant (Siemens S7-300 PLC )

Project Description: Perkins engines company limited installed an engine paint shop plant during a major UK engine manufacturing plant overall in Peterborough. George Koch & Sons as the main contractor needed a systems integrator who could design the control systems, manufacture the control panels, and carry out the electrical site installation/site commissioning. The engine paint plant process main line and booth line consisted of the following:

  • RO plant
  • Manual spray booth
  • Oil separation plant
  • Cure oven with gas burners
  • Paint sludge removal plant
  • Dry off oven with gas burners
  • Paint mix area ( explosive atmosphere area)
  • Automatic engine spray booth containing four Fanuc spraying robots
  • 5 stage fiberglass reinforced plastic system for pre-treatment spray washing of the engines.

Approach: MCS Control Systems paint plant was divided into two separate control systems one the main line and one for the spray booths. Each control panel contained a S7-300 PLC and was interlocked with a site SCADA via an Ethernet network. The main control panels were installed on platforms above the dry off ovens and the cure ovens and all the site SWA cabling was installed on two main cable tray runs along each line.

Results: Working closely with our client the installation and commissioning was completed over a two month period and with the approval of the end client.
