Format of Breakdown Levels In case for eg.

The second character of FN numbers the cubicles. It should be decided on a case- to-case basis which numbering convention is best suited to the extend and structure of the systems and plants to be identified. If necessary, further grouping can be performed by using FN. Simeens code is subject to agreement between the parties to the project.

APPENDIX I: KKS SYSTEM

Deviations with respect to the type of data character A or N and their quantity are allowed by DIN Part 2 and are subject to agreement between the parties to the project. Coding letters and designations of main groups B1 for components as given in the Component Key and for signals and signal applications: Siemesn heat generation Unit control system L.

E — Binary and analog signal and variable conditioning A Grid and distribution systems B Power transmission and auxiliary power supply Codf Instrumentation and control systems D Instrumentation and control systems E Conventional fuel supply and residues disposal F Handling of nuclear equipment G Water supply and disposal H Conventional heat generation J Nuclear heat generation K Nuclear auxiliary systems L Steam, water, gas cycles M Main machine sets N Process energy supply for external users e.

If several process-related systems are situated in one structure we designate this structure according to the main, most important system. All signals in such automatic regulation system in breakdown level KKS 0, 1, 2, are described identically.

Safety equipment, consisting of safety valves and their associated piping, are assigned to the system to which they are connected. Enter the email address you signed up with and we’ll email you a reset soemens. The latter consist of data characters occupied by alpha and numeric symbols.

The prefix symbols may be omitted if the information contents of the codes remain unambiguous. Details of application are subject to agreement between the parties to the project.

Where measured data are corrected e. The outdoor area is designated in the breakdown level 1 by symbols: The result was a series of operations whose sequence was often irrational. Coding letters and designations of the main groups F1 as given in the Function Key: CF means the twelfth local measuring circuit of fluid flow the code CF12 is not correct.

QCG Central chemical supply free for use e. The alphabetical symbols of this breakdown level are used to classify and divide the overall plant into subsystems, systems or building structures.

Equipment Unit-Specific Analog Signal Processing and Measuring Circuits Equipment unit-specific analog signal processing elements comprise control and instrumentation equipment which is only provided for one equipment unit such as control interface, protective logics, instruments in the feeder and command termination for final control elements.

Signals and Signal Applications Breakdown level 3 is used to siemenss signals and their applications. For this purpose, data character B1 can contain: Types of Code and Breakdown Levels 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.

N — Process energy supply for external users e. A standard designation system enables each party, irrespective of dode and assignment, to identify uniformly and unambiguously, those parts of the plant within its responsibility. Kka Service Systems Mechanical service systems which serve more than one main group identified on breakdown level 1 are identified as auxiliary or ancillary systems in separate main groups F1 by means of the following coding letters: Identification in data character A2 is governed by the physical variable.

Identification System for Combined Cycle Power Plant (KKS coding)

Redundant zeros must be written, e. Spaced notation promotes the comprehensibility and mnemonic quality seimens codes. V Lubricant supply system W Sealing fluid supply system X Fluid supply system for control and protection equipment. Total plant Serial no. It is a common practice to apply a grouping numbering of equipment units:
