About the Maintenance lab
Maintenance is keeping a plant running: finding why a pump shakes or a conveyor trips, fixing it safely and writing down what you did. The Maintenance lab in EDWartens Lab is a free 3D plant in your browser, with the instruments a technician carries and a CMMS, the system where the work is planned and recorded.
A made-up packaging plant with a pump skid, a conveyor, a compressor, an air handler, a motor control centre and a hydraulic press. Read the work request, take the as-found readings with the same tools a technician carries, find the cause, fix it in the right order and close the job in a CMMS with the right codes and hours.
The guide
Short answers first. Open a card for the rest.
Each job starts as a work request from a fictional packaging plant. You start the work order, make the job safe, measure before you touch anything, find the cause, fix it, test it and close the work order with the right codes and hours. An automatic acceptance test marks the result.
The equipment is generic and the company is made up, so the lab teaches the method rather than one maker's product. It is a simplified model, not a maintenance standard.
The lab has fifteen levels. You tour the plant and the CMMS, walk a weekly PM route, and find why a pump vibrates with a vibration analyser. You find why a conveyor motor trips, calibrate a level transmitter, find a hot lug with a thermal camera, test a wet motor with an insulation tester and change a leaking seal.
The last level is planning only: set priorities from a matrix, order a missing part, load the crew's hours across the week and read PM compliance and backlog from the history.
Every hands-on job needs a signed permit and a locked, tagged and proved-dead isolation, including the release of stored air, oil or process pressure. The model refuses an unsafe order, records it, and the acceptance test fails however the job ends.
Opening the lab, doing the levels and passing the acceptance tests are free, and you can start without an account. A free EDWartens account records your results and keeps your work on every device. The lab is in beta.

Questions
Yes. The Maintenance lab in EDWartens Lab is a free 3D plant that runs in your browser. You can start without an account; a free EDWartens account records your results.
Yes. The lab has Wartens CMMS, a made-up system with requests, work orders, parts, a PM schedule, stores and reports. A switch shows the matching ERP plant maintenance transaction code on each screen.
Yes. A vibration pen and analyser show the overall level and the spectrum, and a thermal camera shows the heat of the three phases of a feeder. The readings come from a hidden condition you have to find.
No. A real plant has its own permits and procedures. The simulation is practice for the thinking and the order of the work.
