• Troubleshoot conveyor and ASRS automation using SCADA/HMI screens, PLC fault codes, I/O indicators, and device-level diagnostics.
• Resolve faults involving VFDs, 3-phase motors, MDRs, encoders, scanners, photoeyes, and other automation hardware.
• Diagnose industrial networking issues including EtherNet/IP device faults, drive IP conflicts, and communication interruptions.
• Calibrate scanners, cameras, scales, and print-and-apply systems to ensure accurate labeling and tracking performance.
• Rebuild and replace mechanical components such as rollers, belts, bearings, chains, gearboxes, and drive assemblies.
• Perform preventive and predictive maintenance including lubrication, alignment, inspections, and electrical testing.
• Use Maximo CMMS to process work orders, update equipment histories, and document recurring issues for root-cause analysis.
• Ensure full compliance with PPE standards, NFPA 70E electrical safety requirements, and Lockout/Tagout procedures during all maintenance tasks.

• Performed electrical troubleshooting and repair on motors, VFDs, PLC I/O, contactor's, relays, sensors, and process control circuits across plant operations.
• Accessed PLC ladder logic to trace faults, verify input/output states, and diagnose equipment failures impacting production.
• Calibrated and maintained instrumentation including temperature, pressure, proximity, and level sensing devices to ensure stable and accurate process control.
• Conducted preventive and predictive maintenance on electrical systems, drives, control panels, and motors to improve reliability and reduce downtime.
• Responded to breakdowns, performed root-cause analysis, and restored electrical and automation systems to operational status.
• Collaborated with operations, maintenance, and engineering teams to support system upgrades, equipment installations, and electrical/control modifications.
• Updated maintenance records, asset histories, and parts usage within Maximo CMMS to support trend analysis and equipment planning.
• Ensured strict compliance with NFPA 70E electrical safety standards, PPE requirements, and Lockout/Tagout procedures during all troubleshooting and repair activities.
