Control and instrumentation equipment which serves more than one main group may be identified under main group C for control proceduee instrumentation, e. X special structures, Y bridge structures, Z ducting structures.

Current members of the technical committee are: Point of Installation Identification AM Mixers, agitators AN Compressor, fans and blower unit AP Pump units AS Adjusting and tensioning equipment for non-electrical variables to be applied only, if the actuator forms itself a constructive unit with another equipment unit AT Cleaning, drying, filtering and separating equipment and trap, excl. F Process-related Designation The breakdown levels have the following structure: They are made up of classifying and numbering code elements.

The breakdown levels have the following structures: System One should remember, that the code of a system must consist of five symbols: Coding letters and designations of the main groups A1 as given in the Equipment Unit Key: Special Rules for Mechanical Engineering I – 5. Measuring Circuits Measuring circuits comprise analog signal acquisition, conditioning, distribution and measured data recording and indicating processing elements. AN numbering may be consecutive or grouping.

The additional code is used for the numbering of: Supply systems which serve only one equipment unit are identified on an equal footing as subsystems of the system in which they are installed. Structure Code Serial no. Cabinets CJF Boiler control system incl.

Generally valid rules on the use of FN numbering are not expedient. A uniform identification structure, with a maximum of four breakdown levels, was created for all three types; the units referred to becoming smaller from left to right. Room Identification by Numbering Serial no. Calculation of new value on base of 2 variables, e.

Procedure for Plant Identification(KKS Numbering System)

In the electrical and instrumentation control engineering sectors, mks equipment for auxiliary services, power supply, open-loop-control, instrumentation, etc. Safety equipment, consisting of safety valves and their associated piping, are assigned to the system to which they are connected. F3 of the principal process-related task. Introduction Breakdown level 1 System function Serial no. These three types of code use the same identification scheme, procedre is subdivided into four breakdown levels.

W — Renewable energy plants System-related identification is expedient where the supported items are positively assignable to one system.

A — Mechanical equipment The next counting signs of the circuit does not change when is creating only one combined variable. The outdoor area is designated in the breakdown level 1 by symbols: Spaced notation promotes the comprehensibility and mnemonic quality of codes. EB – Conditioning of signals related to single drive control. Subsequent isolation and pressure equalization valves in the measuring circuit are components of the measuring taggging and therefore classified kke KA.

Identification System for Combined Cycle Power Plant (KKS coding)

Format of Breakdown Levels The code is made up of breakdown levels. Types of Code and Breakdown Levels In consideration of tahging various requirements placed on the identification of plants, sections of plants and items of equipment in power station, KKS has three different types of code: X — Heavy machinery not main machine sets In this type of code, the breakdown level 2 contains equipment unit code.

H — Conventional heat generation Because relevant design progress have been done too much. A working party, consisting of planners, operating companies, authorized inspectors and other authorities, was set up in with the task of finding such a solution.

They should be established individually for different control and instrumentation concepts. Measuring Transformers The types of measuring transformers as well as their quantities in the given system are identified in breakdown level 2 by letters GT and three digits.
