graphical symbols for diagrams The series consists of the following parts: — Part 1: General information, general index Cross-reference tables; — Part 2: Symbol elements, qualifying symbols and other symbols having general application; — Part 3: Conductors and connecting devices; — Part 4: Basic passive components; — Part 5: Semiconductors and electron tubes; — Part 6: Production and conversion of electrical energy; — Part 7: Switchgear, controlgear and protective devices; — Part 8: Measuring instruments, lamps and signalling devices; — Part 9: Telecommunications: Switching and peripheral equipment; — Part 10: Telecommunications: Transmission; — Part 11: Architectural and topographical installation plans and diagrams; — Part 12: Binary logic elements; — Part 13: Analogue elements The scope and the normative references for this series are given in IEC 617-1 Symbols have been designed in accordance with requirements given in the future ISO 11714-11) The module size M = 2,5 mm has been used For better readability smaller symbols in this standard have been enlarged to double size and are marked “200 %” in the symbol column To save space larger symbols have been reduced to half size and are marked “50 %” in the symbol column In accordance with the future ISO 11714-1, clause 7, symbol dimensions (for instance height) may be modified in order to make space for a greater number of terminals or for other layout requirements In all cases, whether the size is enlarged or reduced, or dimensions modified, the thickness of the original line should be maintained without scaling 1) The symbols in this standard are laid out in such a way that the distance between connecting lines is a multiple of a certain module The module 2M has been chosen to provide enough space for a required terminal designation The symbols have been drawn to a size convenient for comprehension, using the same grid consistently in the representation of all symbols All symbols are designed within a grid in a computer-aided draughting system The grid which was used has been reproduced in the background of the symbols The older symbols which were included in appendix A of the first edition of IEC 617-7 for a transitional period, are no longer part of this second edition, as they will definitely be withdrawn from use The indexes in Annex B and C include an alphabetic list of symbol names and their corresponding number The symbol names are based on the description of the symbols of this part A general index including an alphabetic list of symbols of all parts is given in IEC 617-1 At present, at the stage of Draft International Standard (document 3/563/DIS) © BSI 10-1998 I.1 II est permis d’ajouter la plupart des symboles un petit cercle vide ou plein pour représenter le point de l’articulation Voir par exemple le 07-02-02 Chapter I: General rules I.1 Dans quelques symboles, le cercle représentant le point d’articulation doit être figuré Par exemple, voir 07-02-05 I.2 Pour d’autres méthodes de représentation d’interrupteurs en particulier les interrupteurs électroniques et complexes voir CEI 617-12, Section 17A et 29 et CEI 617-13, section 17 A small circle, open or filled in, representing the hinge point, may be added to most of the symbols For example, see 07-02-02 In some symbols the circle indicating the hinge point shall be shown For example, see 07-02-05 I.2 For other methods of representing switches, especially complex, electronic switches, see IEC 617-12, section 17A and 29, and IEC 617-13, section 17 EN 60617-7:1996 Chapitre I: Règles Générales ©

commande Dans les cas complexes où il est souhaitable de préciser ce mode de commande, on peut appliquer la place, l’un des symboles 02-13-16 02-13-19 This qualifying symbol may be applied to simple contact symbols to indicate position switches if there is no need to show the means of operating the contact In complicated cases, where it is desireable to show the means of operation, one of the symbols 02-13-16 through 02-13-19 may be used instead Pour représenter un contact actionné mecaniquement dans les deux sens, ce symbole doit être placé des deux cotés du symbole de contact To depict a
