14、 Foreword Foreword Canadian Standards Association provides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Marks on certain products of their manufacture to indicate conformity with CSA Standards. CSA Certification for a number of prod

15、ucts is provided in the interest of maintaining agreed-upon standards of quality, performance, interchangeability, and/or safety, as appropriate. Where applicable, certification may form the basis for acceptance by authorities. Where feasible, programs will be developed for additional products for w

16、hich certification is desired by producers, consumers or other interests. In performing its functions in accordance with its objectives, CSA does not assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and findings of the Association represent its

17、 professional judgement given with due consideration to the necessary limitations of practical operation, and the state of the art at the time the Standard is processed. Products in substantial accord with this Standard but which exhibit a minor difference or a new feature may be deemed to meet the

18、Standard providing the feature or difference is found acceptable utilizing appropriate CSA Certification Division Operating Procedures. Products which comply with this Standard shall not be certified if they are found to have additional features which are inconsistent with the intent of this Standar

19、d. Products shall not be certified if they are discovered to contravene applicable Federal laws or regulations. Testing techniques, test procedures, and instrumentation frequently must be prescribed by the CSA Certification Division in addition to the technical requirements contained in Standards of

20、 CSA. Beyond the markings specified in the Standard, the CSA Certification and Testing Division may require special cautions, markings, and instructions that are not specified by the Standard. Some tests required by CSA Standards may be inherently hazardous. The Association neither assumes nor accep

21、ts any responsibility for any injury or damage that may occur during or as the result of tests wherever performed whether performed in whole or in part by the manufacturer or the Association, and whether or not any equipment, facility, or personnel for or in connection with the test is furnished by

22、the manufacturer or the Association. Manufacturers should note that, in the event of the failure of the CSA Certification and Testing Division to resolve an issue arising from the interpretation of requirements, there is an appeal procedure: the complainant should submit the matter, in writing, to t

23、he Secretary of the Canadian Standards Association. If this Standard is to be used in obtaining CSA Certification please remember, when making application for certification, to request all current Amendments, Bulletins, Notices, and Technical Information Letters that may be applicable, and for which

24、 there may be a nominal charge. For such information or for further information concerning details about CSA Certification please address your inquiry to the Applications and Records Section, Canadian Standards Association, 178 Rexdale Boulevard, Rexdale (Toronto), Ontario MSW 1R3.

Solid-State Speed Controls November 1987 7 C22.2 No. iS6-M1987 8 November 1987 C22.2 No. 156-M1987 Solid-State Speed Controls ScopeDefinitions 1. Scope 1.1 This Standard applies to solid-state, singl

27、e-phase motor speed controls, rated at 300 V and less, 20 A and less, designed to be used in circuits for the control of shaded pole, permanent split capacitor, or universal motors, and other motors suitable for use with this type of control, intended for use in nonhazardous locations in accordance

28、with the Canadian Electrical Code, Part I. 1.2 This Standard applies to controls that may incor- porate a switch to place an air gap in series with the motor; and when provided with a series switch, (a) incorporate solid-state components in a phase shift network to provide a controlled voltage outpu

29、t and designed so that (I) Type I: the ON/OFF function is independent of the output voltage setting; or (ii) Type II: the ON/OFF function can be operated at minimum output voltage setting only; or (iii) Type Ill: the ON/OFF function can be operated at maximum output voltage setting only; or (b) (Typ

30、e IV) incorporate solid-state components to provide one or more, but not an infinite number of positions of control. 1.3 This Standard applies to controls intended for (a) flush mounting; (b) surface mounting; (c) use as a table-mounted control to which a portable motor can be temporarily connected;

31、 (d) installation in other equipment as part of the control package for that equipment; (e) permanent installation in the supply line of a motor; or (f) other similar applications within the general outline above. 1.4 This Standard does not apply to resistor, trans- former, and variable frequency ty

32、pe motor speed controls. 2. Definitions 2.1 The following definitions apply in this Standard: Actuating memberthat part which is pulled, pushed, orturned in operating the control mechanism. Controla solid-state, single-phase motor speed control. Field wiring terminala terminal to which power supply,

33、 equipment control leads, or equipment grounding or bonding connections will be made in the field when the control is installed. Liningan insulating material covering the interior surface of the metal cover or enclosure of a control to prevent electrical contact between bare live parts and the cover

34、 or enclosure. Thermoplastica plastic that repeatedly can be softened by heating and hardened by cooling through a temperature range characteristic of the plastic, and which, in the softened state, can be shaped byflow into articles by moulding orextrusion. Thermoseta material that, after having bee

35、n cured by heat or other means, is substantially infusible and insoluble. Type I controla control in which the ON/OFF function is independent of the output voltage setting. Type II controla control in which the ON/OFF function can be operated at the minimum output voltage setting only. Type III cont

36、rola control in which the ON/OFF function can be operated at maximum output voltage setting only.
