3 Preface to the KKS Application Explanations, issue 2004 With the edition 2004 the layout was adapted on the form used by “VGB PowerTech Service GmbH” since the year 2000 and the text of the Application Explanations B 106 was converted to standardized electronic formats. The VGB Technical Committee “Technical Classification Systems”, often specified in the “KKS Application Explanations”, became to the Working Panel “Reference Designation and Plant Documentation” due to the structural changes of VGB in the last years. A project team, specially installed by the Working Panel, provided also the "KKS Application Explanations for Hydro-Power Plants" which was published in the year 2004. These specific Application Explanations of Hydro-Power, published as B106 D1 supplement the existing explanations around the special interests of the Hydro-Power plants and create the basis for a more efficient engineering and project completion in this field of activity. Correct application of the KKS is the condition that unique identification and rational function in the desired measure is reached. The Application Explanations are supplements to the KKS Guidelines and are intended to give assistance in use of the identification system. Following overview shows the connection between the KKS Definitions and KKS Applications. Essen, in September 2004

Format of Code Types of Code and Breakdown Levels
In consideration of the various requirements placed on the identification of plants, sections of plants and items of equipment in power stations, KKS has three different types of code: Process-related code Process-related identification of systems and items of equipment according to their functions in mechanical, civil, electrical and control and instrumentation engineering Point of installation code Identification of points of installation of electrical and control and instrumentation devices in installation units (e.g. in cabinets, panels, consoles) Location code Identification of locations in structures, on floors and in rooms and also of fire areas and topographical stipulations (surface area grid) These three types of code use the same identification scheme, which is subdivided into four breakdown levels. Originally the titles of the breakdown levels were based on the process-related code: Serial no. of breakdown level Titel of breakdown level
0

The titles of the breakdown levels of the three types of code will be as follows: Serial no. of breakdown level

-
Correlation of the examples with the engineering disciplines
-
Correlation of the examples with the individual parts of the application explanations
Of particular importance is the process-related code. It is used by all engineering disciplines, whether mechanical, civil, electrical or control and instrumentation engineering. As is apparent from the synopsis, it is possible to combine items from different engineering disciplines in one code, for example: Serial no. of breakdown level

Examples of Types of Identification
2.2.1 Process-Related Identification The process-related code serves to identify systems, plants, sections of plants and items of equipment according to their tasks in the power station process. It is used by all engineering disciplines. The examples below illustrate applications in mechanical, civil, electrical, control and instrumentation engineering. The examples also demonstrate combinations of code elements from the various engineering disciplines within a code. Example 1: Identification of a pump in a process-related system Breakdown level

Breakdown symbol
The prefix symbols are necessary because in some applications the same code letters are used on breakdown level 1 for different types of code; consequently confusion is possible if prefix symbols are not entered. The prefix symbols may be omitted if the code remains unique, due to the use of formatted notation in flow diagrams, for example. In the point of installation code the " • " breakdown symbol is placed between breakdown levels 1 and 2. Example: Process-related code:
Cooling unit in cabinet
Point of installation code: Installation space in cabinet
= CHA04 AH001 + CHA04.AH001
The " • " breakdown symbol is necessary for positive distinction between types of code and therefore must always be written. Explanations on this are given in Part B3.

19 The classifying coding letters and designations are established on a non-project-specific basis in the KKS keys as follows: -
Function key, for F1 / F1 F2 / F1 F2 F3 on breakdown level 1
-
Equipment unit key, for A1 / A1 A2 on breakdown level 2
-
Component key, for B1 / B1 B2 on breakdown level 3
The terminology of the key may be modified on a project-specific basis but only provided that the contents are not altered. Modifications to be specified between the parties to the project. "Blocked" coding letters are reserved for future technologies and new systems engineering configurations. They may only be allocated and released by the VGB Technical Committee on Technical Classification Systems. The letters of the alphabet are divided up between the main groups A1 and B1. For this reason certain letters may not be used within each group. 2.4.2 Numbering Code Elements The code elements G, F0, FN, AN, A3 and BN have a numbering function. Serial no. of breakdown level

These numbering code elements are subject to agreement on a project-specific basis and between the parties to the project as regards numbering systems and direction of numbering. However, the following principles apply: As a rule numbering starts anew 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, except as modified below. 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. The subject of numbering systems is dealt with individually for the engineering disciplines in Parts B1 - B4. Statements on the direction of numbering are made below in the sections "Total Plant" and "Prefix Symbols" in the present Part A.

Direction of numbering
Use of an alpha symbol for the data character of breakdown level 0 is recommended since the next data character F0 (prefix number of breakdown level 1) is numeric. Example 13: Identification of units and non-unit-specific plants in a total plant

21 Project-specific local factors are crucial to the direction of numbering (or lettering). The direction of numbering for breakdown level 0 should be established jointly with that for the prefix number of breakdown level 1 (q.v.). The directions of numbering are subject to agreement between the parties to the project prior to the start of identification. However, standard identification schemes take priority. The direction of numbering may be established on the basis of the following considerations: •
Direction of flow of - materials - energy
•
Direction of view from a defined standpoint, for example - from left to right - from bottom to top - from front to rear - from inside to outside
•
Points of the compass
•
Directions of extension
•
Cartesian coordinates
•
Polar coordinates
•
Priorities
Breakdown level 0 may be omitted if the code remains unique. This has to be specified between the parties to the project. The "total plant" breakdown level is identical for all three types of code in all engineering disciplines. It is therefore not dealt with in Parts B1 - B4 of the application explanations.

Prefix number for system code Numbering similar systems and plants referring to F1 - F3 Within the parts of a power station identified on breakdown level 0 the prefix number applies only to the system or plant which is classified in the subsequent alpha data characters. Where multiple identical or similar self-contained systems or plants are identified by the classifying part of the system code (F1 F2 F3), they are consecutively numbered by means of the prefix number. Each prefix number applies to the addressed system only. The prefix number must be written in all codes for the system concerned. The prefix number is not an alternative to the numbering entered in FN or the identification given on breakdown level 0. Use of the prefix number has no effect on the systematics of identification in the other data characters. If there is a risk of confusion between data characters G and F0 in the event of incorrect notation of KKS relative to the data characters, F0 should be written as well. Details of application to be specified between the parties to the project particularly with respect to standard identification conventions. The rules for the prefix number apply in principle to all three types of identification: -
Process-related identification
-
Point of installation identification
-
Location identification
and to all engineering disciplines: -
Mechanical engineering
-
Civil engineering
-
Electrical engineering
-
Control and instrumentation engineering
For this reason the commentary on the prefix number is not repeated in the application explanations for the other types of identification in Part A or in the application explanations contained in Parts B1 - B4.

All rights reserved. The transmission and multiplication of this data is not allowed without the prior permission of the publisher Consulgal SA / Nova Oeiras - Portugal
32 Interfaces: The relevant pages of the Function Key show the interface definitions with the meanings given below:
"from incl."
means "including" the named item
"from excl." means "excluding" the named item "to excl."
means "excluding" the named item
"to incl."
means "including" the named item
Gaps: A number of coding letters in main groups F1 groups F2 and subgroups F3 have been reserved, for example to allow inclusion of future technologies. In main groups A1 and B1, as well as in some subgroups, some coding letters have also been reserved. All reserved coding letters may only be allocated with the agreement of the VGB Technical Committee on Technical Classification Systems. In the Function Key it is not possible to make generally valid rules for certain coding letters in data characters F2 and F3 since they depend exclusively on the configurations and arrangements concerned. Similar considerations apply to A1 = E and G in the Equipment Unit Key. In such cases a remark with the following meaning appears in the key part concerned: "...free for use for"
i.e. the letters thus annotated may be used within the terms of the stated definitions
or "...free for use"
i.e. unreserved letters may be used without any restrictions within the terms of the stated definitions in F1 resp. F2

In process-related identification the direction of flow takes priority over local conventions for orientation, for example. (Combinations with numbering conventions according to direction of flow and local features give rise to conflicts at intersections, e.g. of parallel pipe trains.)
•
The direction of numbering of standardized identification conventions for plants may only be established in accordance with non-project-specific considerations. (Superposition of directions of numbering according to project-specific and local considerations usually destroys the standardized identification convention.)

Component numbering Numbering of components, signals and signal applications Redundant zeros must be written. There are no generally valid rules for the systematics of numbering conventions. Two examples of component identification are given below. Breakdown levels 0 and 1 are not included since the components can be combined in any form with codes from the various engineering disciplines; for example, the fan as a mechanical component is used both in mechanical engineering itself and also in civil, electrical, control and instrumentation engineering applications.

Point of Installation Identification
Identification of points of installation of electrical and control and instrumentation devices in installation units (e.g. in cabinets, panels, consoles). Every process-related equipment unit and every measuring and control circuit requires electrical and control and instrumentation equipment. The process-related, that is, function-related, identification of such items is defined unequivocally under "ProcessRelated Identification". The 'point of installation code' serves to identify the points of installation of electrical components such as switches, indicators and electronic modules. This is necessary for the cabling and wiring of electrical and control and instrumentation equipment for example. Serial no. of breakdown level

46 Special engineering-discipline-specific rules apply to installation unit classification in connection with other F1 main groups. The classifying part of the point of installation code serves to identify hardware facilities such as switchgear, electronic equipment cabinets and control consoles. The coding letters A, B, C, D of main group F1 are identical for both process-related and point of installation identification. Allocation of the many unreserved F2 and F3 data characters is governed by the individual plant concept, i.e. by aspects such as auxiliary power system configuration, hardwired control and instrumentation in conventional technology or combined cabinets or programmable logic systems.
