18、 This document (EN 14597:2012) has been prepared by Technical Committee CEN/TC 247 “Building Automation, Controls and Building Management”, the secretariat of which is held by SNV. This European Standard shall be given the status of a national standard, either by publication of an identical text or

19、by endorsement, at the latest by December 2012, and conflicting national standards shall be withdrawn at the latest by December 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible

20、 for identifying any or all such patent rights. This document supersedes EN 14597:2005. Compared to the previous edition, the following significant technical changes have been incorporated in this European Standard: a) In Clause 3, the classification of the controls to protective control or operatin

21、g control was adjusted. If the letter “S” is used in the abbreviation, the word safety will also be used in the associated definition. Contractions between the definitions in Clause 3 and further requirements in the standard, especially in Table AX of the standard were removed; b) In Clause 11, the

22、action 2V was adapted to the requirements of the standard content; c) In Annex H, the fault modes were adjusted to the existing approaches, a new Annex EX (informative) for characteristics of typical temperature sensors and their fault modes; d) Annex J applies to thermistors; e) Expansion of footno

23、te 205 for requirement 27; also the new footnote 208 for the requirement 27 in Table BX.1. The test specification in requirement 27 was clarified. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European S

25、 the United Kingdom. BS EN 14597:2012EN 14597:2012 (E) 5 Introduction This European Standard specifies the functional requirements and tests for control devices which result from their application in thermal installations. These include, for example, time response and safety aspects of those devices

26、 which enable the safe operation of the installation. A distinction is made between special requirements for the different operating media: air, water, oil and flue gas. This European Standard includes purely mechanical constructions, electrical and electronic constructions, and constructions using

27、software. There exist “standard applications“ for which in the past “typical“ devices or combinations thereof have been used. Some of these devices may also be of purely mechanical construction. Such “standard devices” are described in this document and identified by letter codes. Their properties a

28、nd functions are described in definitions using the language and definitions of the EN 60730 series, so to make sure that existing devices (using the same letter codes) are not incompatible when tested using this document. The devices described in this European Standard contain sensors, control unit

29、s and positioning outputs and, if needed, actuator devices. The requirements for mechanical safety, electrical safety and EMC are covered by the standards of the EN 60730 series under the LVD and EMC Directives. To make sure that when translating this document into other languages, no unintended mea

30、ning is attached to certain words or that words are used as in former practices, the different devices are identified and defined by device codes consisting of up to four letters. It is strongly recommended that no other meaning than that given by the definitions of this document and of the EN 60730

31、 series is attached to the letter codes. This European Standard has been created for temperature sensing controls for use in heat generating systems. It might still be useful however to quote it for other applications, either wholly or in part. Remarks to product committees specifying devices within

32、 the scope of this European Standard to ensure safety of the controlled applications within the scope of their standards: The attention of product committees specifying devices from this European Standard to cover technical risks of the operation of applications within the scope of their standards i

33、s drawn to the following fact. Merely specifying a general type of device (e. g. thermal cut out) according to this document for a specific application does not generally ensure the safety of the controlled application and may indeed be a recipe for disaster. The use of a control itself does not pro

34、vide safety. Rather, safety is only provided if the control is suitable to be used with that application. It is necessary to assess the risk situation of the controlled application by accepted engineering procedures (risk and/or fault analysis, FMEA, or other). It is also necessary to select from th

35、e devices with different device codes given in this document the device(s) that adequately limit the risk to acceptable levels by controlling or preventing possible failures and errors from occurring during operation of the application. In order to limit risk in the controlled applications, controls

36、 as specified in Annex AX of this document need to be used. For control purposes operating controls, and for risk limiting protective controls need to be used. If a protective control also provides operating control functions, any failure of the operating function or part of the control should not p

37、revent the protective operation of the control. This European Standard covers safety related aspects pertaining to the operation and inherent safety of operating and protective controls for heat generating systems. BS EN 14597:2012EN 14597:2012 (E) 6 This European Standard does not limit constructio

38、n to single function devices: multifunctional devices which could be classified for different functions are allowed within specified conditions. In this way, the use of devices using electronics or software is possible. In this European Standard, the term “heat generating system“ can also mean “heat

39、 exchanger“. In this European Standard, the term “heat generating system“ comprises all equipment incorporated in such a system, for which other standards will normally apply as well.
