Chapter 2 - Symbols on schematics

identify various lines on schematics, identifying schematics by their symbols, describe approaches to troubleshooting

what is the logical sequence that a well prepped schematic connects the parts in?

1. power source

2. operating devices in the sequence

3. return to power source

4. circuit is complete

if you see a power source (three horizontal lines) what kind of schematic system would you be looking at?

electrical diagram

if you see a compressor, what kind of schematic system might you be looking at?

piping

what are things that the engineer has to consider before designing the schematic?

1. physical size

2. efficiency

3. if the circuit needs to be shaped to fit a larger system

4. cost

5. codes and other factors

what happens in the drafting process of a schematic?

1. engineer makes several sketches

2. engineer makes several lists of materials

3. engineer can test in a lab if necessary

what happens after the draft of the engineer’s schematic design is approved?

1. the engineer changes the words into symbols

2. the schematic is made
