Master Technician - Senior Start Up

Primary Function The Master Technician
- Senior Start Up will commission, program, optimize small and large CAT generator systems and integrate them with site power infrastructure, including ATS, switch gear, paralleling equipment, and SCADA/controls systems. The role will be the technical authority onsite for initial start-up, functional testing, system programming, troubleshooting, and customer turnover. It requires an expert in CAT controls and power system operation who can ensure systems operate safely, reliably, and in compliance with NEC, NFPA 70/70E/110, IEEE, and Caterpillar commissioning standards.
Essential Duties Generator Commissioning & CAT Controls

Perform full initial start‑up on Caterpillar generator sets from 10 kW to multi‑megawatt units
Program, configure, and troubleshoot all Caterpillar control platforms, including EMCP 2/3/4 series, Cat Digital Genset Controllers, paralleling controls (MCP, LSM), and CANbus/Modbus components
Validate and adjust governor/AVR parameters, load sharing, kVAR/PF controls, droop/isochronous settings, and paralleling logic
Run complete load bank tests (resistive/reactive), step tests, waveform analysis, and transient response testing
Ensure all programming aligns with Caterpillar commissioning standards and site design documents

Automatic Transfer Switch (ATS) Start‑Up, Testing & Troubleshooting

Perform full initial start‑up, functionality testing, and troubleshooting for Caterpillar, ASCO, Eaton, Zenith, ABB, and other ATS manufacturers.
Verify voltage/frequency sensing, time delays, transfer/retransfer logic, and contact/interlock verification
Test closed‑transition/open‑transition operation and verify proper communication with CAT generator controls
Document all ATS test data and ensure compliance with NFPA 110 Level 1/Level 2 requirements

Switchgear Integration (LV/MV)

Possess extensive knowledge of switch gear components, protective devices, interlocking schemes, and control wiring
Perform I/O verification, point‑to‑point checks, and sequence-of‑operations testing
Troubleshoot breaker circuits, sync check circuits, PT/CT circuits, and protection elements
Validate paralleling with gensets and utility and confirm relay configurations
Coordinate with engineering on settings and coordination studies

Troubleshooting & System Optimization

Diagnose issues involving mechanical, electrical, controls, and network communication layers
Perform root‑cause analysis on sync failures, load sharing imbalance, nuisance trips, communication faults, and power quality problems
Adjust CAT controller parameters to ensure stable and reliable performance

Safety, Documentation & Project Execution

Lead on-site safety (NFPA 70E, arc flash boundaries, LOTO, JHAs)
Maintain documentation: commissioning reports, as‑builts, redlines, test results
Provide end‑user training on CAT generator and controls operation
Coordinate with engineers, electricians, utilities, contractors, and inspectors
