This 5 days 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.

Objective

Upon completion of this course, participants will gain the following:

  • 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 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 
  • Troubleshoot several single loop control systems
Audience
  • Instrumentation and control engineers and technicians 
  • Design, installation and maintenance engineers and technicians in the process industries 
  • System integrators 
  • System consultants

Methodology

Highly Interactive program with exercises, individual approach and group role playing alternate with practical statements based on theory and supplemented with practical tips based on actual experience. During the course the first draft of a strategic plan at company or department levels will be made by the participants. Power point presentation will be presenting the main points with appropriate time for discussions. Videos will be watched, Exercises to provide practical experience, and case studies to support different ideas will be supporting the learning. Participants will be encouraged to bring their own experiences and challenge the learned concepts and practices. The course is based on a combination of interactive activities - group and individual exercises, case studies, role plays and discussions - along with formal inputs.
