19、 Requests in P it is the last systematic check before mechanical completion to ensure that: all E all instrumentation and equipment is delivered according to the design specifications if not already verified during FAT or quality check during equipment receiving; installation has occurred in accorda
20、nce to engineering documents, applicable codes and local regulations; loop functionality is correct. This provides that: in a project, the quality check for E the base for the commissioning phase which consists of the following phases: a) cold commissioning phase during which functional testing of e
21、quipment and facilities, using test media such as water or inert substances, takes place; b) hot commissioning (chemical start-up) phase during which activities associated with the testing and operation of equipment using the actual process chemicals (initial start-up of process) are performed. The
22、main activities in the cold and hot commissioning phases are system verification tuning of loops and instruments and control schemes. 5 Loop check content 5.1 Included activities The loop check includes the following elements of a “single loop“ (sensor and/or actuator). Hardware components: the inst
23、alled instruments or components in the field or in their final destination; IEC 2057/06 BS EN 62382:2013 10 62382 IEC:2012 the equipment in E hard wired functionality between sensor and actuator loops (if applicable); the input and output (if applicable) cards of process control systems. The basic s
24、oftware components (including the graphic faceplates, base level alarms and switch points, basic interlocking and basic analogue control) to test the field devices. The loop check uses the basic graphics/faceplates of the control system (see Figure 2). Note that primary inputs and outputs may be con
25、nected not only to DCS but also to ESD, PLC, unit controllers and other subsystems. They all are visualized on DCS. The actual loop check involves the three following phases (see details in Clause 6): a) Documentation checkout Check for the completeness and consistency of loop documents, including a
26、ny documents from the installation or FAT. b) Visual inspection of loop devices for correct installation and tagging. c) Function check A testing device is used to exercise all the components of the loop (including hardware, wiring and software). It checks that all the components function correctly
27、and that the DCS or panel readouts are accurate. 1)Check of the operational configuration is completed during cold commissioning or hot commissioning. Figure 2 Loop components During the loop check the following three types of deficiencies can be found: d) Installation failures Installation failures
28、 are discrepancies with the specified hardware or the method of installation (wrong installation, wrong instruments, etc.). The construction contractor should fix these problems. e) Configuration failures IEC 2124/12 BS EN 62382:201362382 IEC:2012 11 Configuration failures are discrepancies with the
29、 original software specification. The programming contractor or E etc.) These problems should be corrected by E other factory acceptance tests performed at the contractor or vendors factories; other software checkout activities (FAT,etc.); detailed construction and mechanical inspections performed d
30、uring the construction phase: cable testing during construction (Hipot, Meggering, etc.); point-to-point wiring checks; the testing of the internal workings of package units (i.e. process subunits, machinery, complex analysers, etc.) is excluded; only the I/O testing of this equipment is included in
31、 the loop check; activities belonging to the commissioning phase: tuning of loops, instruments and control schemes (for example, calibrating of level transmitters by filling tanks; verification of complex control schemes; tuning of continuous control schemes; etc.). 6 Loop check procedure 6.1 Docume
32、ntation check The documentation check consists of the following activities. The checkout of the loop should first establish that all documentation pertaining to that loop is available, consistent and correctly labelled if the loop is a safety, quality or environmental loop. The pertinent documentati
33、on shall, as a minimum, contain a loop diagram and a specification containing all calibration and functional data necessary to verify the correct operation of the loop (loop sheet). 6.2 Visual inspection The visual inspection consists of the following activities. The installation should be visually
34、checked against the documents to ensure that the correct instruments were installed and that the installation is in accordance with the hardware specifications and loop diagrams/circuit diagrams. Valves and flowmeters are checked for correct installation with the direction of flow. Can local instrum
35、entation be easily read? Are all the elements of the loop available, accessible, labelled and installed in a clean and neat manner (including junction boxes, panels, cabinets, racks)? Is the tagging clear and unambiguous (no danger of false interpretation)? BS EN 62382:2013 12 62382 IEC:2012 Are the
36、 field elements adequately protected from mechanical or environmental damage? 6.3 Function check 6.3.1 General The function checks concerning field devices are ideally performed in well defined blocks (related technical blocks like process units or related racks in E checking of behaviour of the liv
37、e list (fieldbus). 6.3.3 Actuators Functional checking of actuators is as follows. Checking of tag number and parameters. If the loop has an analogue output, the actuator should be observed to verify that it follows the incremental output changes within a specified tolerance. Simulation of an actuat

Disconnection of actuator, checking of the failsafe position and the failure reaction in DCS. Reconnection of actuator, checking if device is correctly and automatically init

Checking of parameters in motor protection device, compare with motor data Simulation of motor protection devi

Checking of correct operation with motor protection device in test mode and removed motor fuses Checking of correct function of local ON/OFF switches BS EN 62382:201362
41、382 IEC:2012 13 6.3.5 Inter-loops The check of inter-loop functionality (like analogue control loops or interlock functions) is preferably done for integrated units after a successful checkout of the separate sensor and actuator loop. This is most effectively completed during cold commissioning. IMP

46、 are drafted in such a way that all relevant items are covered at least once. BS EN 62382:201362382 IEC:2012 15 Quality is guaranteed by the following measures: The loop check is always performed in the same manner (independent of the particular tester). Test reports are updated with the latest info
47、rmation. The testers confirm with their signature that a complete loop check agrees with the test procedures. 9 Safety aspects For safety installations, extra checklists and working plans are set up in addition to the normal loop-check procedure. These documents typically describe a very detailed ch
48、eck procedure and are periodically repeated after production start-up. BS EN 62382:2013 16 62382 IEC:2012 Annex A (informative) Test report for analogue input loop Instrument type:1.
