AUBURN – The Corporate and Community Services Department at Central Maine Community College will offer a non-credit course in Programmable Logic Controllers (PLCs) and Motor Controls, starting Jan. 18. The class will meet from 6 to 9 p.m. Wednesdays through May 3. The cost of $625 includes all materials.

Part one of the program will cover basic motor control concepts and their application to automated systems, including three-phase motors, manual and magnetic motor starters and push button circuits.

Emphasis will be placed on three phase principles, calculations, motor connections, basic motor control circuits, article 430 of the National Electrical Code and interpreting schematics. Applications include the testing of three-phase motors and connecting them to basic motor control circuits.

The second part of the course will cover Programmable Logic Controllers (PLCs), which monitor inputs and in turn control outputs to automate a process or machine.

Specific emphasis will be placed on ladder logic programming. Students set up hardware addressing on the PLC racks/modules and verify physical wiring of real world devices. They establish communications between a computer and a PLC processor using Rockwell’s RSLinx software.

Ladder logic programs are written for Allen Bradley’s PLC5 Programmable Controller using RSLogix5 software. Applications include the simulated control of electric motors and other industrial control circuits.

The instructor will be Lou Maranda, an industrial power and control systems designer for Alexander and Associates, an engineering firm based in Cincinnati, Ohio. He has been designing, installing and programming industrial control systems in the Lewiston/Auburn area for more than nine years.

Maranda has extensive training in Allen-Bradley PLC implementation, troubleshooting and programming from Rockwell Automation. As a Maine-licensed master electrician, he also has professional experience with commercial and residential electrical systems.
