This Seminar targets the need for technicians/engineers to operate, maintain, calibrate and troubleshoot control systems such that availability and reliability can be maximized. This is accomplished by thoroughly understanding concepts of gas turbine control systems and how to use maintenance screens to quickly determine problems.

PREREQUISITES:
It is recommended (not required) that participants have attended OR have the equivalent knowledge/background of HPC's Combustion Turbine Familiarization Seminar prior to attending this (GE) Mk-IV Gas Turbine Controls Seminar.

OBJECTIVES:
Upon successful completion of this Seminar the participant should be able to:
  1. Demonstrate the ability to use OEM provided documentation that will include the Control Specifications, Elementaries, Application Manual, and P&IDs.
  2. Demonstrate the understanding of the Mk-IV hardware components, how they are accessed, and how they communicate.
  3. Demonstrate the ability to troubleshoot an equipment alarm, given an Alarm Drop Number.
  4. Demonstrate the ability to interpret the more routine diagnostic alarms and recognize appropriate actions.
  5. Demonstrate the ability to follow the major "control signal path" through the elementaries.
  6. Demonstrate the ability to trace the derivation of a command signal to the servo-mechanisms.
  7. Demonstrate the knowledge necessary to calibrate turbine valve mechanisms.
  8. Demonstrate the ability (or knowledge -- based upon equipment availability) to more efficiently use the Mk-IV screens for evaluating/calibrating systems.
  9. Demonstrate the ability (or knowledge -- based upon equipment availability) to force logic to facilitate calibration.
  10. Describe how to change constants or re-program ladder logic such as to add contact input/outputs, add alarms, and/or alter sequencing.
  11. Given plant drawings, trace a signal to/from a field device through appropriate terminal boards, through circuit boards, to a digital "signal name".
  12. Demonstrate the ability to follow signal flow to/from the "4" circuits to trip/reset the machine.
