• Describe or demonstrate how to read raceway diagrams.
• Explain how to use a "Raceway Notes, Symbols, and Detail" reference.
• Explain how to use a raceway schedule.
• Describe or demonstrate how to locate specific components or pieces of equipment in a plant.

Raceway Diagrams, Part 2

• Describe how to apply a raceway diagram and its associated references to extract information about a plant.
• Define percent fill.

Logic Symbols

• Explain what logic gates are.
• Explain how truth tables are organized.
• Name five types of logic gates and explain under what conditions each has an output.

Logic Diagrams

• Describe or demonstrate how to read a logic diagram.
