For this purpose, data character B1 can contain: Fictitious rooms in structures may be identified by numbering or coordinate systems. Filters in ventilation and air conditioning systems. Identification System for Combined Cycle Power Plant KKS coding Bearing in mind the scale of power plants being built up to the early sixties, the Plant Identification System AKS could be regarded as adequate for the needs of planning and construction engineers at that time. Regulation part is described in level 1 by process-related installation, and level 2 by the controlled parameter — control part is described by executive device e. Requirements to be met by the Identification System Mechanical Supports Supports may be identified using the system code or the structure code. EM — Conditioning of signals related to functional measurement group in digital system.

Single line diagrams are the basic documents origins for a project related KKS coding in electrical engineering. For other engineering activities e. The original KKS number is still kept, even when another kind of equipment is used providing that the function according to the KKS equipment unit code is not changed e.
If in a project hardware component is no longer used, it is not allowed to re-allocate its KKS number for another component in the same project.
Numbering starts a new when one of the preceding code elements changes. Numbering may be consecutive or grouping. Numbering need not be continuous. Numbering conventions, once established, may not be altered, not even in the event of changes made in the progress of planning. Redundant zeros must be written. An application-specific scheme of numbering may be established. However, such schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline.
Management systems e. If necessary, subdivisions of number ranges in Fn and An according to the division of work could be made.
They have to be written down directly in the Function key code and must be respected by the partners. Numbers are increased in media or process flow direction. The counting is related to any geographical direction. Main cooling water pump motor In two lines.
Procedure for Plant Identification(KKS Numbering System)
Single line diagrams are the basic documents origins for a project related KKS coding in electrical engineering. For other engineering activities e. The original KKS number is still kept, even when another kind of equipment is used providing that the function according to the KKS equipment unit code is not changed e. If in a project hardware component is no longer used, it is not allowed to re-allocate its KKS number for another component in the same project. Numbering starts a new when one of the preceding code elements changes.
KKS TAGING PROCEDURE PDF
Ararg Where signals or measured data are used to limit or suppress the original measured data, the processed output signals retain the code of the original measured data. In this application, however, a suitable identifier such as a prefixed Y should be used to indicate that a software coding unit is concerned, thus to rule out confusion with process-related codes. Read from left to right no data characters may be omitted. According to the standard, the prefix sign can be omitted provided that the identification remains unambiguous.
KKS TAGGING PROCEDURE PDF
Kazrar They are generally identified after the system within the interfaces of which the sensor is installed. A breakdown level tagibg is used to identify the installation space. Room Identification by Coordinates Serial no. G — Electrical devices E — Conventional fuel supply and residues disposal The same applies to structures in civil engineering work. The following principles direct for the designation of installation point in assembly units: Installation Unit Code Serial no. When technical installations differs only with counting signs of installation it is necessary to assign to a secondary variable counting signs like for one of those installations e.
Codes, Tags and Labels—Interpreting Piping and Instrumentation Diagrams
Kazracage Modern methods of digital systems programming and ability of efficient use of technical documentation require to use the concept of functional group positions A1 and A2 and number of the group positions An — three numerals depending on degree of complexity of automatic analog control system. F Process-related identification In this type of identification the entire system is subdivided according to the function or process, since, whether for mechanical, electrical, control of civil engineering, the equipment units and components must be identifiable in relation to the process. In the meantime, the AKS has been adopted as the main system of identification in a number of conventional and nuclear plants. Data character G as well as data character F0 can be omitted in KKS if the further part of designation will remain complete univocal. The result was a series of operations whose sequence was often irrational. The next counting signs of the circuit does not change when is creating only one combined variable. However, such schemes may not have the effect of reserving numbers in other applications, not even within the same engineering discipline.
