Automatic Electrical Controls for Household and Similar Use; Part 2: Particular Requirements for Electric Actuators

SKU116325299 Published by Underwriters Laboratories Inc. UL Publication Date2021-11-30 Pages CountPages41

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.

This part 2-14 applies to

electric actuators

powered by primary or secondary batteries, requirements for which are contained within the standard, including Annex V.

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.

Replacement of third and fourth paragraphs of 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.

Modification of 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.

Replacement of 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.

Modification of 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.

1.1.5 Void.

1.1.6 Void.

1.1.7 Replacement:

This part 2-14 applies also to

electric actuators

incorporating

electronic devices

, requirements for which are contained in Annex H.

1.1.8 Replacement:

This part 2-14 applies also to

electric actuators

using NTC or PTC

thermistors

, requirements for which are contained in Annex J.

1.1.9 Replacement:

This part 2-14 applies to the electrical and

functional safety

of

electric actuator

s capable of receiving and responding to communications signals, including signals for power billing rate and demand response.

The signals may be transmitted to or received from external units being part of the

electric actuator

(wired), or to and from external units, which are not part of the

electric actuator

(wireless) under test.

1.1.10 Replacement:

This part 2-14 does not address the integrity of the output signal to the network devices, such as interoperability with other devices unless it has been evaluated as part of the control system.
