Title: Lab 3-4: Motor Control Circuit with Permission
Course: Electrical Motor Controls (Sandbox) > Section: Module 3: Common Control Circuits, 20 hr

Introduction

Now that you know how to run a motor via two "Start" buttons and two "Stop" buttons, you will build a circuit that causes the motor coil to become energized when you press and then release the "Start" button if, and only if, the permission button is closed. The motor coil should remain energized until either the "Stop" button is pressed, the overloads are tripped, or the permission button is opened.

The following video will walk you through the steps of building the circuit according to the schematic shown below.

Lab Instructions

1. Watch the video introduction to this lab.
2. Draw a schematic diagram, in Automation Studio or by hand, that represents a circuit that will operate as described above. Make sure your circuit works in simulation before moving on to the next step.
3. Unplug the Motor Controls trainer.
4. Build the circuit on the Motor Controls trainer.
5. Plug in and turn on the Motor Controls trainer.
6. Test the circuit.
7. The motor coil is energized when a user presses and then releases the "Start" button if, and only if, the permission button is closed. It remains energized until either the "Stop" button is pressed, the overloads are tripped, or the permission button is opened.

Submission

To complete this lab, submit a 30-second video following the criteria found in the rubric. If you are working with another student, each of you must record and submit your own video.
