This seminar is for electricians (or maintenance personnel) who work with electrical/electronic drawings and circuits. Circuit requirements, logic and applications are covered. Includes converting standard ladder (line) diagrams into PLC diagrams. Troubleshooting using prints and circuit modifications is also covered.

You will learn

  1. How to read and understand architectural drawings, ladder diagrams, wiring diagrams and other types of electrical diagrams.
  2. How to draw and understand electrical symbols and abbreviations.
  3. How to connect and troubleshoot circuits that include 2-way, 3-way, 4-way, motion sensing and other types of switches.
  4. How to connect and troubleshoot circuits that include lamps and receptacles.
  5. How to connect and troubleshoot the control and power circuit of basic single-phase and three-phase motor circuits.
  6. How to convert standard line diagrams into PLC diagrams.
