INTRODUCTION

Industrial systems often require both a safety switch and an operator command before a machine will run. This prevents accidents and allows flexibility for multiple operators. You’ve practiced wiring up the core logic functions—AND, OR, and NOR. In this assignment, you’ll use that knowledge to build a circuit where a maintained switch and one of three buttons must be pressed to turn on a light.

HEADING

In Automation Studio, draw a schematic that will turn on a light when a Maintained Switch is closed AND Button 1 OR Button 2 OR Button 3 is pressed.  Make sure your circuit works in simulation before moving on to the next step.

LAB INSTRUCTIONS

1. In Automation Studio, draw the schematic (see above). Make sure your circuit works in simulation before moving on to the next step.
2. On the Motor Controls Trainer, build the circuit you drew in Automation Studio.

• Watch the video introduction to this lab.
• Unplug the Motor Controls trainer.
• Build the circuit on the Motor Controls trainer.
• Plug in and turn on the Motor Controls trainer.
• Test the circuit.

SUBMISSION

• Submit a screenshot of your complete circuit in Automation Studio.
• Submit a video in which you describe and demonstrate the operation of the circuit on the trainer.  Videos should be no more than 30 seconds long.
