answer all questions by your worlds

questions:

1. Describe the four different parts of a limit switch.
2. Describe a scenario where a machine’s PLC program could be the cause of a production error.
3. Describe a typical application for each of the following switches: flow, level, pressure, vacuum, and temperature.
4. Why is it unusual to have multiple unrelated failures, how can this knowledge be used in troubleshooting?
5. What are position-sensing switches, and how are they used?
6. What is the difference between open loop and closed loop control in op. amps? Which mode is more widely used?
7. Contactors often have auxiliary contacts. For what can they be used?
8. Describe feedback control. What is it used for?
9. Why does a contactor have a thermal overload? How does it work? Describe a scenario where it might be of value.
10. What steps are used to create a system block diagram?
11. What is the zener effect? What is the primary application of this effect in industrial electronics?
12. Compare solid state relays to electromechanical relays. Provide two benefits and two potential downsides to solid state relays vs. electromechanical relays.
13. What are the names of the terminals of a transistor?
14. Describe an idea or skill that you learned during lab that you believe will be valuable for your career. Why will it be valuable?
15. If you could change one aspect of this class, what would that change be?
16. If you could plan a lab period for this class what would it be like? Address these issues: topic, lab activities, student prep work (what lecture activities would support the lab), resources required, and estimated instructor/student time commitment.

My rational during grading will be as follows:

• for answer clarity. Was this answer clear, concise, and easy to understand?
• for effort. Was there an appropriate amount of thought and time put into the creation of this answer? That doesn’t necessarily mean a long answer. If a short response answers the question well, it is appropriate. If more detail is required to answer the question well, a longer answer is appropriate.
• Multipart questions reflecting a higher potential point total.
