Troubleshooting Electrical Control Circuits
Description
Develop a solid foundation in electrical control circuit troubleshooting knowledge and skills. You will learn techniques that will help locate faults quickly. About 70% of the time is spent in hands-on lab exercises at a troubleshooting station with motor control circuits (operating at a safe, low level of 24 volts). During this course, you will find out how analog signals are produced, processed and protected from noise and the differences in proportional, PI and PID control strategies. Understand what causes errors in instruments and how to minimize and troubleshoot them. Learn how to calibrate transmitters and tune controllers.
If you’d like to expand your knowledge by also learning about the basics of industrial electricity, we recommend this 4-Day hands-on course: Industrial Electricity and Troubleshooting Electrical Control Circuits
