**Aero Instrumentation & Controls Technician / Gas Turbine Mapper**

===================================================================

**Candidates must be US Based**

**This position requires travel to sites in various locations.**

The Aero Instrumentation & Controls Technician I / Gas Turbine Mapper is responsible for the inspection, disassembly, cleaning, repair, calibration, testing, troubleshooting, and periodic maintenance of instrumentation, control systems, and associated equipment on GE aeroderivative gas turbines.

The position requires hands-on experience with gas turbine instrumentation and controls, including field instrumentation mapping, electrical and control system troubleshooting, calibration, software modifications, and control system upgrades.

The Technician will evaluate equipment conditions, identify and diagnose operational issues, determine necessary repairs or modifications, and perform complex troubleshooting and maintenance activities during scheduled outages, commissioning, startup, and unscheduled maintenance assignments.

The role requires the ability to interpret electrical schematics, P&IDs, instrument drawings, control logic, and OEM technical documentation to identify, trace, verify, and document instrumentation and control system components. The Technician will also support control system software upgrades, modifications, retrofits, and functional testing to ensure proper turbine operation.

Experience with GE aeroderivative gas turbines, including LM2500, LM6000, LMS100, or similar equipment, is highly desirable.

**Essential Duties & Responsibilities:**

• Provide customers with technical direction and support on the calibration, repair, maintenance, troubleshooting, and operation of instrumentation and controls equipment associated with GE aeroderivative gas turbines.
• Perform detailed instrumentation and control system mapping, including identification, tracing, verification, and documentation of field instruments, control devices, wiring, terminal connections, and I/O assignments.
• Verify instrument tag numbers, device locations, signal paths, wiring connections, and control system interfaces against electrical schematics, P&IDs, loop diagrams, instrument lists, and OEM documentation.
• Identify and document discrepancies between installed equipment, existing technical drawings, and control system configurations. Prepare instrument mapping records, updated device lists, and redline drawings as required.
• Disassemble, inspect, clean, repair, calibrate, test, and perform periodic maintenance of field instruments, control devices, and associated equipment systems.
• Troubleshoot, reinstall, test, evaluate, calibrate, and maintain instruments or devices following repairs, modifications, or replacement.
• Diagnose and troubleshoot electrical, instrumentation, and control system problems involving sensors, transmitters, switches, actuators, control valves, and associated electrical circuits.
• Perform instrument loop checks, signal verification, continuity testing, I/O verification, and functional testing to confirm proper equipment and control system operation.
• Record and report abnormal equipment functions, instrumentation failures, and out-of-tolerance conditions. Identify required corrective actions and maintain appropriate documentation.
• Troubleshoot gas turbine control systems, including PLC hardware, I/O modules, communication interfaces, control logic, and associated instrumentation.
• Review, interpret, and troubleshoot PLC ladder logic, control sequences, permissives, alarms, trips, and turbine protection logic.
• Implement approved conversions, modifications, upgrades, and retrofits to gas turbine control systems, including software upgrades, logic modifications, and configuration changes.
• Support control system software backups, configuration verification, software revision control, and post-modification functional testing.
• Provide technical support for GE Mark V, Mark VI, Mark VIe, Woodward NetCon, MicroNet, MicroNet Plus, and other applicable gas turbine control systems.
• Support troubleshooting and maintenance of gas turbine auxiliary systems, including fuel control, vibration monitoring, overspeed protection, fire and gas detection, and other turbine protection systems.
• Support troubleshooting and modifications involving Human Machine Interface (HMI) systems and associated software applications.
• Read and interpret electrical and mechanical flow diagrams, instrument diagrams, wiring schematics, P&IDs, control logic drawings, and equipment specification manuals.
• Use hand tools, electrical testing equipment, multimeters, loop calibrators, and other specialized instrumentation tools to conduct maintenance, troubleshooting, and testing of customer equipment.
• Support turbine startup, shutdown, commissioning
