Instrument Troubleshooting (Interlock & Control Circuitry)

AudienceInstrumentation technicians or operators. Process or control system engineers may also benefit from this course.

DescriptionThis course is flexible enough to meet individual troubleshooting skills from entry level to the most experienced technician. The workshop is designed to teach the techniques and methodology of troubleshooting circuitry used to interlock equipment or control field devices. Emphasis on voltage checks, neutrals, grounds, relay logic, PLC logic, DCS logic, print reading skills and safe use of test equipment assures immediate benefits. The workshop is 90% hands-on activities solving simple to complex problems through the use of IEC Simulations' schematics, interlock Simulator and test equipment. Individual skill level assessments are documented and average performance improvement in troubleshooting efficiency is 87%. May be used by client for PSM Compliance issues involving 3-year frequency for proof of knowledge, skills and abilities.
