AS/NZS 1102.102:1997
This Joint Australian/New Zealand Standard was prepared by Joint TechnicalCommittee TE/13, Symbols, Units and Quantities for Electrotechnology. It wasapproved on behalf of the Council of Standards Australia on 19 September 1997 andon behalf of the Council of Standards New Zealand on 19 September 1997. It waspublished on 5 December 1997.
The following interests are represented on Committee TE/13:
AirServices AustraliaThe Association of Consulting Engineers, AustraliaAustralian Chamber of Commerce & IndustryDepartment of Employment & Technical & Further Education, S.A.Department of Defence, AustraliaInstitution of Engineers, AustraliaInstitution of Radio & Electronics Engineers, AustraliaMinistry of Commerce, New ZealandQueensland Mining CouncilRoyal Melbourne Institute of Technology
Review of Standards. To keep abreast of progress in industry, Joint Australian/New Zealand Standards are subject to periodic review and are kept up to date by the issueof amendments or new editions as necessary.It is important therefore that Standards usersensure that they are in possession of the latest edition, and any amendments thereto.Full details of all Joint Standards and related publications will be found in the StandardsAustralia and Standards New Zealand Catalogue of Publications; this information issupplemented each month by the magazines The Australian Standard and StandardsNew Zealand, which subscribing members receive, and which give details of newpublications, new editions and amendments, and of withdrawn Standards.Suggestions for improvements to Joint Standards, addressed to the head office of eitherStandards Australia or Standards New Zealand, are welcomed. Notification of anyinaccuracy or ambiguity found in a Joint Australian/New Zealand Standard should be madewithout delay in order that the matter may be investigated and appropriate action taken.
This Standard was issued in draft form for comment as DR 97171.Acc

PREFACE
This Standard was prepared by the Joint Standards Australia/Standards New Zealand CommitteeTE/13, Symbols, Units and Quantities for Electrotechnology. It is issued as a Joint Standard tosupersede AS 1102.102 1989. It is based on but not equivalent to, and reproduced from,IEC 617-2, Graphical symbols for diagrams , Part 2: Symbol elements, qualifying symbols and othersymbols having general application .The objective of this Standard is to provide users of electrotechnical documents with symbolelements, qualifying symbols and other symbols having general application for the purposes ofuniformity and clarity in presenting electrotechnical diagrams.The Part numbers in this series of Standards correspond to equivalent Parts in the IEC 617 seriesbut with 100 added to the IEC 617 Part number. For example, for the Standard IEC 617-2 refer toAS/NZS 1102.102. The symbol numbers within this Standard are the same as the IEC 617 numbers.In AS 1102.101, Graphical symbols for electrotechnical documentation , Part 101: Generalinformation and general index, the first part of the symbol number refers to the Part number, e.g. inthe index, for symbol 102-01-01, refer to Part 102, symbol 02-01-01.In this Standard, Australian and New Zealand variations have been listed in Appendix ZA and,accordingly, the source text should be amended, supplemented or replaced as required. The changesto the source text are indicated with a marginal bar against each clause, table, figure or part thereofaffected. Appendix ZA provides symbols for use in Australia and New Zealand which are additionalto, or alternative to, the IEC 617 symbols. The symbols are identified with an A in the third partof the symbol number.Appendix ZB contains information which is not contained in Annex A, on the changes from thesuperseded Australian Standard to this Part of the Standard.The terms normative and informative have been used in this Standard to define the application ofthe appendix to which they apply. A normative appendix is an integral part of a Standard, whereasan informative appendix is only for information and guidance.As this Standard is reproduced from an international Standard, the following applies:(a) Its number appears on the cover and title page while the international Standard number
appears only on the cover.(b) In the source text, this International Standard should read this Australian/New Zealand
Standard.(c) A full point substitutes for a comma when referring to a decimal marker.References to international Standards should be replaced by equivalent Australian or Australian/New Zealand Standards, as follows:Reference to International Standard Australian or Australian/New Zealand StandardIEC AS617 Graphical symbols for diagrams

INTRODUCTION
Symbols have been designed in accordance with requirements given in the future ISO 11714-1. Themodule size M = 2,5 mm has been used. For better readability smaller symbols in this standard havebeen enlarged to double size and are marked 200 % in the symbol column. To save space largersymbols have been reduced to half size and are marked 50 % in the symbol column. In accordancewith the future ISO 11714-1, clause 7, symbol dimensions (for instance height) may be modified inorder 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 lineshould be maintained without scaling.
The symbols in this standard are laid out in such a way that the distance between connecting lines isa multiple of a certain module. The module 2M has been chosen to provide enough space for arequired terminal designation. The symbols have been drawn to a size convenient forcomprehension, using the same grid consistently in the representation of al l symbols.
All symbols are designed within a grid in a computer-aided draughting system. The grid which wasused has been reproduced in the background of the symbols.
The older symbols which were included in appendix A of the first edition of IEC 617-2 for atransitional period, are no longer part of this second edition, as they will definitely be withdrawn fromuse.
The indexes in Annex B and C include an alphabetic list of symbol names and their correspondingnumber. The symbol names are based on the description of the symbols of this part. A general indexincluding an alphabetic list of symbols of al l parts is given in IEC 617-1.

7SECTION 3 ADJUSTABILITY, VARIABILITY AND AUTOMATIC CONTROL
3.1 Adjustabili ty is a kind of non-inherent variabil ity which enables to perform an adjustment, i.e. to set the variable quanti ty on a suitable value.3.2 Variabili ty is non-inherent when the variable quanti ty is controlled by an external device, for example, when the resistance is controlled by a regulator.
3.3 Variabili ty is inherent when the variable quantity depends on quali ties of the device itself , for example, when the resistance changes as a function ofvoltage or of temperature.
3.4 The sign for adjustabili ty and variabili ty should be drawn across the main symbol at about 45 to the centre line of the latter symbol.

9SECTION 4 DIRECTION OF FORCE OR MOTION
4.1 An arrow may be used to indicate the direction in which the movable part of a device shall move to give a required effect (see the example ofsymbol 02-04-02).It may also indicate the direction of a force or the direction of motion of the physical part symbolized. In such cases a note to indicate the view point maybe required.
4.2 The effect caused by movement may be explained by symbols or by a text.
No. Symbol Description02-04-01 Unidirectional force
Unidirectional rectil inear motion
in the direction of the arrowhead.
