Answers and Explanations

  1. The student must show their face in the video for credit.
  2. The student must wear safety glasses covering their eyes to get credit.
  3. The student must submit a legible schematic. See the examples below for this lab schematic. Only one schematic is required for submission, but either or both are acceptable. The student can either show the industrial style or the electronic style, and they can show either with or without the latch.

  4. The student must have their name, date, and lab number on the schematic.
  5. The wire colors must be on the schematic.
  6. All components must be labeled. This includes circuit breakers, push buttons, switches, motors, fans, solenoids, resistors, etc.
  7. The circuit must be wired to their schematic.
  8. The circuit has to work. The circuit works as follows: 24VDC is run to the SPDT switch in the breadboard. When the switch is on, the relay energizes. When the switch is off, the NC contacts will be connected, and 24VAC from the circuit breaker box will provide power to the light and it will be on. When the switch is on, the NC contacts will open turning off the light and the NO contacts will close turning on the buzzer.
  9. The student clearly shows lockout/tagout in their video.
  10. The student clearly shows that they have verified with a multimeter that the voltage is at or near 0V.
