The numerical digits count and subdivide the unit e. A — Mechanical equipment Control and Instrumentation Equipment I – 5. The prefix symbols may be omitted if the information contents of the codes remain unambiguous. 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.

The outdoor area is designated in the breakdown level 1 by symbols: This rule does not refer to direct measurement circuits, which apply to technical installation and physical variable.

Further applications are subject to agreement between the parties to the project. Usually the code is written above the line: Control and instrumentation equipment which serves more than one main group may be identified under main group C for control and instrumentation, e.

Function-Interfacing Analog Signal Processing Where control and instrumentation equipment serves more than one process system identified in F2 and F3, the letter Y for generic control and protection systems may be used in the appropriate data character on breakdown level 1. This code unit can be combined with any breakdown level as necessary for identification.


Format of Breakdown Levels Special Rules for Civil Engineering Main machine sets Given fod possibilities shown in the table, it is not practicable to meet all possible requirements for identification of discrete process-related function e. These analog signal processing elements receive the code of the equipment unit concerned.

X and Y zones are outside the grid. Introduction The table below shows the designation and type of data characters identtification for equipment unit code. Total plant Serial no. In case of single closed regulation circuits, it is divided into 2 parts: The additional code is not an alternative code for the components identified under breakdown level 3.

Generally valid rules on the use of FN numbering are not expedient. 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. The AN number of breakdown level 2 is used to number the items of equipment classified in A1 and A2.

Where individual structures for which separate structure codes exist are combined to form one structure, that structure is given the code of the most important individual structure.

This draws clear divisions between power plant installations and systems, and takes full account of the needs of manufacturers, operators, inspectors and other authorities as well as the technical requirements of the mechanical engineering, process engineering, civil engineering, and electrical and control engineering sectors. P — Cooling water systems Signals and Signal Applications Breakdown level 3 is used to identify signals and their applications.


Equipment Unit Code Equipment Unit Code consists of two letters, three digits and sometimes one additional letter data character A3 which can be omitted. Feed water system Control and protection system for steam, LY.

Identification System for Combined Cycle Power Plant (KKS coding)

Where several mechanical systems identified differently in data characters F2 and F3 are connected to one mechanical service system, the following code letters are used for the service systems on breakdown level 1 in the data characters concerned as follows: QCG Central chemical supply free for use e. Originally the titles of the identificstion levels were based on the process-related code: The Equipment Unit identified in breakdown level 2 belongs always to the System designated in ffor level 1.

X special structures, Y bridge structures, Z ducting structures.

Equipment Unit Identification In the 22010 code which is the most important and mostly applied type of codes in every branch of engineering, the entire system is subdivided according to the function or process. The next counting signs of the circuit does not change when is creating only one combined variable.

Point of Installation Sysstem Control and Instrumentation Equipment They should be established individually for different control and instrumentation concepts. Special Rules for Mechanical Engineering I – 5. S — Ancillary systems H — Conventional heat generation Read from left to right no data characters may be omitted.

D — Control systems Codes may be spaced by the insertion of blank spaces or interposing lines at predetermined points and by multiple- line notation:
