Fault Diagnosis and Troubleshooting in Control Systems

This course teaches a systematic approach to troubleshooting and start-up as they apply to single and multi-loop control loops. Covers how pressure, level, flow, and temperature loops operate to maintain good process control systems. Knowledge of instrumentation and control is assumed.

• Understand why a systematic approach to troubleshooting is most effective
• Follow specified procedures for proper loop check-out
• Verify, locate, and identify performance problems and the causes of the problems
• Take or recommend appropriate follow-up procedures to minimize problem recurrence
• Identify the common causes of sensor, transmitter, controller, and final control element problems
• Troubleshoot control systems
• Apply DCS functions for troubleshooting
• Understand pneumatic and electronic loops
• Apply safety practices for start-up
• Check and utilize the control loop documentation
• Diagnose and solve problems related to single-loop control loops
• Diagnose and solve problems with ratio, cascade, and three-element control loops
• Diagnose problems using DCS displays for information
• Construct and tune a feedback control loop
