AMENDMENT 1
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to IEC 62386-304:2017 has been prepared by IEC technical committee 34:
Lighting.
The text of this Amendment is based on the following documents:

Replace the existing text, including the Note, with the following new text:
This part of IEC 62386 is applicable to input devices that provide illuminance level information
to the lighting control system through light level sensing.
This document is only applicable to input devices complying with IEC 62386-103:2022.

4.3 Insulation
Replace the first paragraph, excluding the Note, with the following new paragraph:
According to applicable safety standards, it can be required that the input device has at least
supplementary insulation to accessible parts. This depends on the connected components. In
this case special attention should be paid with respect to the sensor(s) being used.

9.3 Input signal and value
Replace the existing paragraph and Note with the following new text:
The measured value shall contain the measured illuminance with a precision of "resolution" bits
and shall be encoded in "inputValue" as described in IEC 62386-103:2022, 9.8.2. The measured
value shall be a strictly monotonic function of the illuminance level.
NOTE The illuminance value is a relative value, not representing absolute lux values.
After receiver start-up, it can take the sensor some time before valid illuminance level
measurements are obtained. During this time, "inputValue" shall be MASK. After the first valid
illuminance level measurement is obtained, "inputValue" shall not be MASK, except in the case
of physical sensor failure (see 9.6.1).
Examples of "inputValue" MASK values and highest valid values, for several values of
"resolution":
– "resolution" = 4: "inputValue" is a 1-byte value
• MASK
