1 Scope and normative references

This clause of Part 1 is applicable except as follows:

1.1 Replacement:

This part 2-14 applies to ELECTRIC ACTUATORS for use in, on, or in association with equipment for household and similar use. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof.

NOTE Throughout this standard part 2 the word "equipment" means "appliance and equipment."

EXAMPLE 1 ELECTRIC ACTUATORS for appliances within the scope of IEC 60335.

This International Standard is applicable to CONTROLS for building automation within the scope of ISO 16484.

This part 2-14 also applies to automatic ELECTRICAL CONTROLS for equipment that may be used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications.

EXAMPLE 2 CONTROLS for commercial catering, heating and air-conditioning equipment.

This part 2-14 is also applicable to individual ELECTRIC ACTUATORS utilized as part of a CONTROL SYSTEM or CONTROLS, which are mechanically integral with MULTIFUNCTIONAL CONTROLS having non-electrical outputs.

EXAMPLE 3 Independently mounted water valves, CONTROLS in smart grid SYSTEMS and CONTROLS for building automation systems within the scope of ISO 16484-2.

This part 2-14 does not apply to automatic ELECTRIC ACTUATORS intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard.

1.1.1 This part 2-14 applies to the inherent safety, to the OPERATING VALUES, OPERATING TIMES and OPERATING SEQUENCES where such are associated with equipment safety and to the testing of ELECTRIC ACTUATORS used in or in association with equipment.

NOTE Requirements for specific OPERATING VALUES, OPERATING TIMES and OPERATING SEQUENCES may be given in the standards for appliances and equipment.

This standard is also applicable to the FUNCTIONAL SAFETY of LOW COMPLEXITY SAFETY RELATED SYSTEMS and CONTROLS.

This part 2-14 does not apply to ELECTRIC ACTUATORS which are mechanically integrated with valves covered by a separate part 2, e.g. IEC 60730-2-8.

This part 2-14 does not apply to electric motors, requirements for which are contained in IEC 60034.

1.1.1DV.2 Replacement of third and fourth paragraphs of 1.1.1 with the following:

This part 2 does not apply to electric actuators which are mechanically integrated with valves. See UL 60730-2-8, Standard for Automatic Electrical Controls for Household and Similar Use; Part 2: Particular Requirements for Electrically Operated Valves, Including Mechanical Requirements or the Standard for Electrically Operated Valves, UL 429.

This part 2 does not apply to electric motors, requirements for which are contained in UL 1004 series of standards.

1.1.1DV.4 Modification of 1.1.1 by adding the following paragraph:

Electric actuators intended for plenum use are covered under the scope of this standard.

1.1.2 Requirements for manual switches not integral with an ELECTRIC ACTUATOR are contained in IEC 61058-1.

1.1.2DV.1 Replacement of 1.1.2 with the following:

Requirements for manual switches not integral with an electric actuator are contained in UL 61058-1.

1.1.3 Replacement

This part 2-14 applies to a.c. or d.c. powered ELECTRIC ACTUATORS with a rated voltage not exceeding 690 V a.c. or 600 V d.c.

1.1.3DV.1 Modification of 1.1.3 by adding the following text:

The maximum current is unlimited.

1.1.4 Replacement:

This part 2-14 does not take into account the RESPONSE VALUE of an AUTOMATIC ACTION of an ELECTRIC ACTUATOR, if such a RESPONSE VALUE is dependent upon the method of mounting the ELECTRIC ACTUATOR in the equipment. Where a RESPONSE VALUE is of significant purpose for the protection of the USER, or surroundings, the value defined in the appropriate household equipment or as determined by the manufacturer shall apply.

Summary of Topics

This revision of ANSI/UL 60730-2-14 is being issued to reaffirm approval as an American National Standard. No changes in requirements are involved.
