Electrical Troubleshooting MS 2.8

Test your troubleshooting skills with a selection of 17 starter problems. Practice real-life troubleshooting scenarios of a 3-phase motor starter using a voltmeter and PLC logic.

Completely free of charge with no advertisements or pop-ups!

Upon startup, the app places users in normal mode. This setting allows individuals to gain hands-on experience in the following areas:

• Understanding the operation of a reversing starter.
• Utilizing virtual voltmeter probes to measure voltages at different test points (indicated by small black squares) in the control circuit.
• Analyzing the PLC logic when the starter is in different control modes (Run, Off, and Auto).

The Human Machine Interface (HMI) solely controls functions when in Auto mode. The selector switches perform as expected within the control circuit.

Once users comprehend how the motor starter operates under various control modes, they can challenge their troubleshooting capabilities by initiating the "New Problem" feature to enter troubleshooting mode. A random problem will be introduced into the control circuit, prompting users to assess if the motor runs with the selector switch set to both "RUN" and "AUTO". By utilizing the voltmeter probes and PLC logic screen, individuals must identify the issue. Once confident with their diagnosis, they can select "Problem Identified". If unable to determine the problem, there is an answer available at the bottom of the list.

This app serves as an invaluable educational tool for anyone looking to enhance their ability to troubleshoot a three-phase reversing motor starter.
