Introduction

This is the final project of this course.

Background

In this project, you'll design a circuit that will run the dumping mechanism of a large dough mixer like the one shown below.

Notice how the operator needs to use both hands in order to run the machine. This is for safety. By designing a control panel that requires the operator to use both hands, we ensure that the operator's hands are not in a place where he or she could get injured while the machine is in motion.

With this in mind, you are given the following control panel to use:

Assignment

The following must be followed and/or included in your circuit:

Lab Instructions

  1. Unplug the Motor Controls trainer.
  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. Build the circuit on the Motor Controls trainer.
  4. Plug in and turn on the Motor Controls trainer.
  5. Test the circuit.
  6. Design, build, and demonstrate a circuit that runs the dumping mechanism of a large dough mixer

Extra Credit

For double the points on this lab, add two sensors to your control circuit that will stop the motor when it has reached its full range of motion. In other words, when the container is in the "Full Dump" position, a sensor will de-energize the forward coil, even if the operator is still holding the buttons. When the container is in the "Full Upright" position, a sensor will de-energize the reverse coil, even if the operator is still holding the buttons.

Because you only have two hands with which to demonstrate the circuit, this extra credit may be done just on the schematic. But feel free to wire it if you want to, using limit switches as your sensors.

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.
