    This course presents a systematic approach to troubleshooting and start-up of single- and multi-loop control loops. You'll see how pressure, level, flow, and temperature loops operate to maintain good process control systems. Knowledge of instrumentation and control is assumed.

    You will be able to:

    • Develop a systematic approach to troubleshooting
    • Identify 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 distributed control system (DCS) functions for troubleshooting
    • Interpret pneumatic and electronic loops
    • Apply safety practices for start-up
    • Check and utilize control loop documentation
    • Discuss applications and procedures to troubleshoot conventional analog control systems
    • State the general operation features of a HARTTM control system
    • State the general operations features of a FIELDBUS control system
    • Compare general troubleshooting procedures for conventional, FIELDBUS, and HARTTM control systems
