Seminar Overview

This two-day course delivers an essential skill in the field of equipment maintenance, installation or modification: the ability to read and understand electrical ladder drawings, schematics and diagrams. The course covers several types of industrial control prints for a variety of different motor-driven processes, with an emphasis on the differences between type and the purposes and flow of each.  Students will participate in exercises to create schematic diagrams based on circuit descriptions and will learn to interpret schematic drawings in order to provide verbal or written circuit descriptions.

This 2-day seminar is just $1100.
