Summary
This 2-day intensive course is for electrical maintenance workers looking to gain an in-depth, hands-on understanding of complex control circuits.
Description/Agenda
This two-day course is designed for electrical maintenance workers looking to gain additional in-depth hands-on understanding of complex controls and control circuits. It is recommended that this course to be taken only after completion of the Electrical Troubleshooting & Preventive Maintenance course.
Hands-on lab activities are the focus of this course. Throughout the day, participants will troubleshoot on a large variety of systems components, ranging from forward/reversing motor control circuits to proximity switches and float switches. Anyone who wants a chance to spend quality hands-on time and build expertise with components seen every day throughout their facilities will gain a great value from this course.
