Job Summary:
The Loop Check and Control Technician is responsible for performing loop checking, functional testing, calibration verification, and commissioning support of instrumentation and control systems in industrial plants, oil & gas facilities, and EPC projects. The role ensures that all field instruments, control systems, and signal loops are correctly installed, wired, configured, and operating as per design specifications before plant startup.
Key Responsibilities
- Perform loop checking of instrumentation and control systems (4–20 mA, digital, pneumatic, and fieldbus signals).
- Verify wiring, termination, and signal continuity between field instruments and control systems (DCS/PLC/SCADA).
- Conduct functional testing of control loops including sensors, transmitters, valves, and actuators.
- Assist in pre-commissioning and commissioning activities for industrial and EPC projects.
- Test and validate I/O signals from field instruments to control panels and control rooms.
- Troubleshoot wiring, signal, and communication issues in instrumentation loops.
- Coordinate with instrumentation engineers, commissioning engineers, and electrical teams.
- Check calibration status and verify instrument accuracy before system startup.
- Ensure compliance with loop diagrams, P&IDs, and instrumentation drawings.
- Maintain loop check sheets, test reports, and commissioning documentation.
- Support system integration testing (SIT) and factory acceptance testing (FAT/SAT).
- Ensure adherence to safety procedures and permit-to-work systems during site activities.
- Assist in punch listing and system handover documentation.
Required Skills
- Strong knowledge of instrumentation systems and control loops
- Understanding of PLC, DCS, and SCADA systems
- Ability to read P&IDs, loop diagrams, and wiring schematics
- Knowledge of analog and digital signal testing (4–20 mA, HART, etc.)
- Troubleshooting and diagnostic skills
