AM Mixers, agitators AN Compressor, fans and blower unit AP Tafing 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.
X Signal origins Y Signal applications Z Gated signals No generally valid rules have been made for signal tagign application areas. Their use for any intended purpose is subject to agreement between proceduee parties to the project. Spaced notation promotes the comprehensibility and mnemonic quality of codes.
System isolation valves for measuring circuits are identified on the level of the equipment unit code by the classifying letters AA. FN numbering is governed by the following principles: B — Mechanical equipment YB71 XB72 Control room; close, down Special guidelines apply to data characters G, F0 and A3.
A2 identifies control and instrumentation functions e. Identification of the functional groups involved in process-related tasks so as to relate them to the principal task concerned may be performed by using the alpha characters in F There are also cases of deviations taaging in using the dividing symbol twice, and AN, e. The AN number must consist of three digits.
S — Ancillary systems Usually the code is written above the line: Equipment unit prpcedure consists of 2 letters data characters A1 and A23 digits data characters AN and sometimes 1 letter data character A3 which can be, and often is omitted. According to the standard, the prefix sign can be omitted provided that the identification remains unambiguous. Notation of Codes The code may be written with or without spacing but procedkre such a way that it cannot be misinterpreted.
A – Grid and distribution systems for electric power plants, thermoelectric power plants and heating plants Coding letters and designations of main groups B1 for components as given in the Component Key and for signals and signal applications: In case of single closed regulation circuits, it is divided into 2 parts: F Equipment Unit Key, groups A1: Tooth Numbering System Word File tooth no.
F General rules on other numbering code elements Fn, An, Bn. The process-related identification is for many applications the most important identification, since it permits, for example, locations of electrical and control equipment, rooms, signals, and the identification in circuit diagrams related to particular functions.
Process-Related Identification Process-related identification of systems and items of equipment according to their function in mechanical, civil, electrical and control and instrumentation engineering.
AL According to cubicles, divisions, sections etc. Feed water system Sealing fluid supply system for LB. Wherever possible, all three alphabetical symbols are permanently allocated, including their associated boundary constraints and task allotment in modern power plant technology.
If necessary, further grouping can be performed by using FN. H — Conventional heat generation Details of application are subject to agreement between the parties to the project.
V Lubricant supply system W Sealing fluid supply system X Fluid supply system for control and protection equipment. Because relevant design progress have been done too much. In case for eg. This code unit can be combined with any breakdown level as necessary for identification. The numerical digits count and subdivide the unit e. Codes may be spaced by the insertion of blank spaces or interposing lines at predetermined points and by multiple- line notation: 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.
Format of Breakdown Levels The code is made up of breakdown levels. This code is subject to agreement between the parties to the project.
Further applications are subject to agreement between the parties to the project.
