Verification should be by signal tracing, continuity verification, or “ringing out”. The wiring of each control loop should be physically verified from the field device terminals to the controller.Ĭable, conductor, terminal board and terminal designations should be verified and marked off as such on a copy of the loop diagram or equivalent schematic or wiring diagram. Process Flow Diagrams (PFD) Loop Verification The below list shows some of the documents. We need different types of documents that are used during instrumentation projects. A Final Control Element Certification sheet should be completed for each control valve and included in the system documentation.An Instrument Certification sheet should be completed for each instrument and included in the system documentation.Each calibrated instrument should be field-marked with a waterproof calibration tag bearing the range, setpoint, date and calibrator’s initials.Stroke actuators and verify control action, limits, and end switches.All calibration equipment should have current independent certification of accuracy.All sensors, elements, indicators, transmitters, and actuators should be calibrated from NIST- traceable standards according to the manufacturer’s instructions.The calibration program should include the following: Instrument and actuator calibration should be completed prior to the loop checkout or startup of systems. Electrical conductors should be tested for continuity and insulation resistance according to industry standards for their voltage ratings. Pneumatic lines should be pressure tested per ISA RP 7.1 and checked for obstructions.

Physical and information security measuresįor example, PLC systems providing control of standby generators and paralleling switchgear should be factory tested with the switchgear to demonstrate the actual operation of the breakers and other controls with simulated utility and generator voltage and frequency sources.Operation of all outputs with dummy load.

Procedures for correction and retesting in the case of failure.Ī factory acceptance test and demonstration should be required in which the controller(s), I/O, and HMI hardware and software are verified to the extent possible without the actual field devices.įAT test should demonstrate the following:.

Clear definition prior to testing of the criteria for acceptance.

Review of these procedures by all affected parties prior to testing.

Development of written testing and verification procedures for every critical aspect of system performance.

An organized system of commissioning documentation.

Integration of commissioning activities into the overall project schedule.

A clear definition of the process and the parties’ roles and responsibilities (Commissioning Plan).

In either case, certain key components of the program that must be included for a successful outcome: If an independent engineer is not used, the design engineer should be retained to oversee the commissioning process. In some cases, an independent engineer may be brought in to coordinate and oversee the commissioning process. The roles and responsibilities of the various parties within the commissioning process may vary with the agency and the type of project. Those represented should include as a minimum: A commissioning team should be assembled including representatives of all involved parties. Commissioning is the formal process of verifying and documenting that the installed field instruments and control systems comply with and perform in accordance with the design intent.Ĭommissioning should be identified as a specific activity requiring its own planning, scheduling, management, and monitoring during the design and construction process.
