      • The trainee will present its work to other trainees and instructor during an other module.
      • Mini-Project - Team Work (2 days)
      • Each team has to identify the priorities for an assigned instrumentation subject submitted by the lecturer.
      • Specific hazards and barriers, critical process variables, critical pieces of equipment, critical operations.
      • Team oral presentation of the results.
  • Module 5: MAINTENANCE OF DCS (Distributed Control System) LOOPS

      • DCS: technologies, controller, DCS architecture, power supplies. Application: DCS architecture review. Practical works.
      • Control schemes: single, cascade and split-range control, ratio and overrides, controller tuning.
      • Application: PID controller tuning (workshop on process simulators).
      • DCS loops troubleshooting: DCS loops drawings, troubleshooting methodology. Applications: DCS loops wiring analysis (from field to control room); DCS loops maintenance procedure writing. Applications and practical works.

      • PLC and relays: technologies, controller, power supplies, programming tools. Application: electrical motor commands review (on site).
      • Logic: logic gates, typical function blocs (bypass, voters…). Application: PLC programming (in workshop).
      • Safety Instrumented Systems (SIS): process role, safety matrix, SIL, SIS specific requirements for maintenance.
      • Troubleshooting methodology. Applications and practical works.
      • Applications: SIS loops wiring analysis; PLC logic diagram analysis; SIS loops test procedure writing; test of a safety transmitter.
  • Module 7: ON THE JOB TRAINING 2 & FINAL TEST (valves, DCS & PLC)

      • OJT (3 days):
      • Application of the previous module(s) content to the actual plant. The subject is submitted by the lecturer.
      • At the end of the OJT period, the trainees will be requested to prepare a written report and a 20 minutes presentation about “Valves, DCS and PLC loops maintenance in process units”: process role of the selected loops and control valves; safety (work permit, risk analysis, safeguards…); selected instrument specification review; detailed maintenance procedures (calibration and overhaul); results analysis (accuracy, acceptance criteria…).
      • Final test (2 days):
      • Presentation of OJTs to the classroom.
      • Written test about all the training contents according to the IFP Training Certification procedure.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • range, configure and commission instruments,
  • troubleshoot field instruments and instrument loops,
  • perform calibration checks in workshop and on the field,
  • write maintenance procedures related to instrumentation.

Ways & Means

  • Training split into thematic modules and “On The Job Training” (OJT). To give participants the opportunity to better assimilate the content of the previous course modules and apply the studied subjects to the facilities.
  • Workshop practice.
  • Exercises on site.
  • If available, use of dynamic benches.
  • Use of process simulators.
  • Intermediate and final tests to evaluate trainee according to IFP Training certification procedure.
