5、nt (EN 14597:2012) has been prepared by Technical Committee CEN/TC 247 “Building Automation, Controls and Building Management” (Secretariat: SNV, Switzerland). The responsible German body involved in its preparation was the DIN-Normenausschuss Heiz- und Raumlufttechnik (DIN Standards Committee Heati

This standard has been included in the body of technical rules and st
7、andards for gas issued by the DVGW Deutscher Verein des Gas- und Wasserfaches e.V. (German Technical and Scientific Association for Gas and Water). Amendments This standard differs from DIN EN 14597:2005-12 as follows: a) in Clause 3, the classification of the controls to protective control or opera
8、ting control has been 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, have been removed; b) in C
9、lause 11, the action 2V has been adapted to the requirements of the standard content; c) in Annex H, the fault modes have been adjusted to the existing approaches and a new Annex EX (informative) for characteristics of typical temperature sensors and their fault modes has been included; d) Annex J a
10、pplies to thermistors; e) the footnote 205 for requirement 27 has been expanded and a new footnote 208 for requirement 27 has been included in Table BX.1. The test specification in requirement 27 has been clarified. Compared with DIN EN 14597:2012-09, the following correction has been made to the Ge
11、rman version only and therefore does not affect the English text: a) in Annex DX, Subclause DX.11.219, second indent, the operating cycles have been corrected to read “2 106operating cycles” (instead of 2 105operating cycles).

DINEN 14597:2015-02EN 14597:2012 (E) 5 Introduction This European Standard specifies the functional requirements and tests for control devices which result from their application in thermal instal
33、lations. These include, for example, time response and safety aspects of those devices 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 mecha
34、nical constructions, electrical and electronic constructions, and constructions using 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 devi
35、ces” are described in this document and identified by letter codes. Their properties and 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 d
36、ocument. The devices described in this European Standard contain sensors, control units 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
37、 make sure that when translating this document into other languages, no unintended meaning 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
38、 other meaning than that given by the definitions of this document and of the EN 60730 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 applicati
39、ons, either wholly or in part. Remarks to product committees specifying devices within 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
40、technical risks of the operation of applications within the scope of their standards is 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 applica
41、tion and may indeed be a recipe for disaster. The use of a control itself does not provide 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 procedure
42、s (risk and/or fault analysis, FMEA, or other). It is also necessary to select from the 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 operati
43、on of the application. In order to limit risk in the controlled applications, controls 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 contro
44、l functions, any failure of the operating function or part of the control should not prevent 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.
45、 DIN EN 14597:2015-02 EN 14597:2012 (E) 6 This European Standard does not limit construction 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
46、 possible. In this European Standard, the term “heat generating system“ can also mean “heat 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. Examples are given below
