SPEEDTRONICtm Mark IV
Troubleshooting Training Course
Objective
This five (5) day SPEEDTRONICtm Mark IV controls training course will provide sufficient knowledge in the theory of operation. Students will obtain and understand key information, which will enable them to correctly monitor the system while developing their ability to prioritize, diagnose and correct problems. Using the provided documentation, students will be able to locate and accurately define system information and specifications, diagnostic aids, troubleshooting procedures, and safety precautions. If the class contains both Heavy Duty and Aeroderivative Customers, both turbine control systems will be covered.
Prerequisite
Participants should have experience in GE gas turbine operation, including normal start up, loading and shutdown, a working knowledge of the various systems, an understanding of PC based computers including DOS based operating systems, SPEEDTRONICtm Mark IV operation, and familiarity with the Instruction Book materials containing maintenance and operation publications.
Course Equipment
Access to a SPEEDTRONICtm Mark IV panel will be part of the course for hardware familiarization and as part of the hands-on troubleshooting exercise.
Course Documentation
Each participant will be provided with a copy of the SPEEDTRONICtm Mark IV Maintenance Manual, User's Manual, Elementary and Elementary Reading Aid, Control Specification, Piping Schematics, Piping Device Summary, Nomenclature Summary, and the Mark IV Newsletter book.
