Loop Check and Control Technician

The Mid-Level Loop Check and Control Technician is responsible for executing detailed loop testing and verification activities across automation and control systems. This role ensures all instruments, wiring, and control elements are properly installed, calibrated, and integrated with PLC/DCS systems as per engineering design and functional requirements.

✅ Key Focus Areas:

1. Loop Testing & Verification

   • Conduct end-to-end loop checks from field instruments (sensors, transmitters, actuators) to control system I/O.

   • Verify analog and digital signal integrity, scaling, polarity, and functionality.

2. Troubleshooting & Rectification

   • Diagnose and resolve issues such as signal loss, wiring errors, calibration mismatches, and configuration inconsistencies.

   • Coordinate with I&C engineers and electricians to implement corrections.

3. Documentation & Reporting

   • Complete loop check sheets, redline P&IDs, loop diagrams, and as-built records.

   • Maintain accurate test logs and update project punch lists.

4. Instrumentation Knowledge

   • Work with a variety of field instruments: pressure, flow, level, temperature transmitters, control valves, limit switches, etc.

   • Familiar with common protocols (HART, 4–20 mA, Modbus, etc.).

5. Control System Integration

   • Assist in signal mapping and I/O testing in PLC/DCS environments.

   • Coordinate with automation teams during logic validation and interlock testing.

6. Safety & Regulatory Compliance

   • Adhere to site safety standards, especially in hazardous or GMP-regulated environments.

   • Follow QA/QC processes and ensure testing complies with project validation protocols.

7. Mentoring & Peer Support

   • Guide junior technicians during loop check preparation and execution.

   • Share best practices for cable management, documentation, and troubleshooting.

Qualifications:

• Education:

  • Diploma or ITI in Instrumentation, Electronics, Electrical Engineering, or related technical discipline.

• Experience:

  • 3–5 years of experience in instrumentation loop testing, commissioning, or control systems integration.

• Skills:

  • Proficient in reading loop diagrams, wiring schematics, and control logic.

  • Skilled in using multimeters, loop calibrators, and test equipment.

  • Experience in pharmaceutical, food & beverage, or industrial automation projects is preferred.
