“The software is working out great. It’s worth making sure that our new maintenance people go through the programs and now it’s going to be a mandatory part of their training. I’ve seen the difference in the few people I’ve run through. The more practice I can get these new troubleshooters the better.”

The simulations

Troubleshooting Motor Circuits includes a motor lab and several motor circuit components labs where you can learn about motor circuit concepts.

The industrial garage door simulation included in this module contains components such as three-phase motors, transformers, contactors, overloads, fuses, push buttons and limit switches.

Troubleshooting scenarios cover both three-phase power circuits as well as the control portion of these motor circuits. The simulations contain over 50 circuit malfunctions to solve with faults containing:

  • Operate the garage door both electrically and manually
  • Take voltage, resistance, and current readings with a multimeter
  • Inspect, Repair and Replace electrical and mechanical components
  • Disconnect and ring out wires, and
  • Trace and replace wires

This simulation contains over 50 circuit malfunctions to solve with faults with a variety of issues, such as:

  • Broken wires and loose connections
  • Wires shorted to ground
  • Defective motors and other components
  • Mechanical defects
