Hands-On Electrical Troubleshooting II

In this course you will learn the functions of: off-delay timers, photo-electric sensors, and alternating relays – all while working with motor starters, selector switches, push buttons, control relays, and timers as well as how to properly troubleshoot three phase electric motors.

Compared to Hands-on Electrical Troubleshooting I, you can expect to wire, troubleshoot and repair more challenging electrical circuits. You will build electrical circuits that represent common industrial uses such as tank fill control and duplex-pump control and then repair them after the instructor has inserted a realistic fault. The instructor will work with you one-on-one to find and fix the problem. You will also learn and apply, through hands-on exercises, how to properly test and troubleshoot three phase motors.

This course is hands-on and gives each attendee the opportunity to work with real electrical components – while building and troubleshooting from ladder diagrams. If you have already attended Hands-On Electrical Troubleshooting I, this course will be a nice compliment to the knowledge you have gained. To insure the quality of this program, this course has limited seating.
