Title: Lab 4-4: Using a Timing Relay, Part 2
Course: Electrical Motor Controls (Sandbox) > Section: Module 4: Control Relays and Timing Relays, 20 hr

Introduction

Background

Timing relays can be set up in different ways to give us different kinds of delays. We are using what is called a TON (Timer On-Delay) timer. There are other kinds of timers, too, but using the contacts on this timing relay in different configurations can give us different results.

Assignment

Can you explain what the below circuit will do? Take a look at it and think about how it will work. Then, build it to see if you were right.

Now that you know how to apply timing relays and TON timers, you will build the next circuit according to the schematic shown below.

Lab Instructions

1. Unplug the Motor Controls trainer.
2. Build the circuit on the Motor Controls trainer.
3. Plug in and turn on the Motor Controls trainer.
4. Test the circuit.
5. The light is delayed according to the TON timer.

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.
