How a lab works

  1. Panel Lab schematic of the 24 V control circuit with wire numbers, and the 415 V power circuit starting below it01

    Read the brief

    A client work order says what the job must do, with a drawing or an I/O list to work from.

  2. Control cabinet with the door swung open, showing the gold backplate with breakers, contactor, PLC and terminals02

    Do the job

    Work in 3D, with the tools a site engineer uses: meters, testers, editors, trends and charts.

  3. Factory acceptance test sheet marked accepted 5 of 5, listing each test with its criterion and a green PASS03

    Pass the test

    An acceptance test checks your work. Sign in to record it and download the report.

Questions

Is the lab free?

Yes. Opening the labs, doing the jobs and passing the acceptance tests are free. Only optional extras, such as an engineer review of your report, are paid. The lab is in beta.

Do I need an account?

No, not to start. You can open any level and work straight away. A free EDWartens account records your test results, lets you rate a lab and keeps your work on every device.

Will my work be saved?

Yes. Your work is saved as you go, on your device while you are signed out. When you sign in, it moves to your account, so you can carry on from any device.

Does it work on a phone?

Yes. Every lab opens on a phone, and nothing is installed. Wiring and programming are easier on a laptop, where you get the best view of the 3D scenes.

Is it finished?

No. The lab is in beta. Report anything that looks wrong with the Report a bug button and we fix it.

How does it connect to the internships on edwartens.com?

Lab tasks sit inside the weeks of our virtual internships. You do the task in the lab, and it closes in your internship when its acceptance test passes. An internship is training, not employment, and there is no stipend.
