Title: Lab 3-10: Design a Control Circuit for Three Conveyors
Course: Electrical Motor Controls (Sandbox) > Section: Module 3: Common Control Circuits, 20 hr

Introduction

This lab will be done differently from your previous labs. For this lab, you will do everything in Automation Studio, and you will not use the trainer for this lab.

Complete a schematic diagram for a control circuit that runs three motor conveyors in a line. Conveyor A feeds material to Conveyor B, Conveyor B feeds material to Conveyor C, and Conveyor C dumps the material into a pile. See the picture below for reference.

In a system like this, we want a control circuit set up such that if Conveyor C fails, the conveyors feeding material to it (both Conveyor A and B) are automatically shut down. If Conveyor B fails, we'll want Conveyor A to automatically shut down.

Your lab must follow the following parameters:

- Each conveyor has its own motor starter, which includes overloads.
- Only one "Start" and one "Stop" push-button may be used to control the conveyor system.
- Include a light for each conveyor to show the operators which conveyors are running.
- Build the schematic in Automation Studio, and test it out in simulation.

Submission

To complete this lab, submit a 30-second video of the circuit you created in Automation Studio. Run the simulation and describe how it works. The video must follow the criteria found in the rubric. If you are working with another student, each of you must record and submit your own video.
