Introduction

In Module 1, you built a circuit that energizes a motor coil when a button was pressed and held. When you let go of the button, the motor coil de-energized. A motor circuit that works this way is called a "Jog" circuit. Throughout Module 3, you built several circuits that energized a motor coil when you pressed a start button, and de-energized the motor coil when you pressed a stop button. We call this a "Run" circuit.

Can you create a circuit that will work as a "Jog" circuit or a "Run" circuit, depending on which is selected? That is exactly what you will do for this lab. You will use only one start button and one stop button. You will also use one maintained switch to choose between "Run" and "Jog". 

The following video will walk you through the steps of building the circuit.

 

 

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. Design, build, and demonstrate a circuit that will work as a "Jog" circuit or a "Run" circuit, using a maintained switch to select between the two modes. 

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.
