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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION


This first edition of IEC 62386-207 is published in conjunction with IEC 62386-101 and

IEC 62386-102. The division of IEC 62386 into separately published parts provides for ease

of future amendments and revisions. Additional requirements will be added as and when a

need for them is recognised.


This International Standard, and the other parts that make up the IEC 62386-200 series, in

referring to any of the clauses of IEC 62386-101 or IEC 62386-102, specify the extent to

which such a clause is applicable and the order in which the tests are to be performed. The

parts also include additional requirements, as necessary. All parts that make up

IEC 62386-200 series are self-contained and therefore do not include references to each
other.
Where the requirements of any of the clauses of IEC 62386-101 or IEC 62386-102 are
referred to in this International Standard by the sentence "The requirements of IEC 62386-
1XX, clause ‘n’ apply”, this sentence is to be interpreted as meaning that all requirements of
the clause in question of Part 101 or Part 102 apply, except any which are inapplicable to the
specific type of lamp control gear covered by Part 207.
All numbers used in this International Standard are decimal numbers unless otherwise noted.
Hexadecimal numbers are given in the format 0xVV, where VV is the value. Binary numbers
are given in the format XXXXXXXXb or in the format XXXX XXXX, where X is 0 or 1; 'x' in
binary numbers means 'don't care'.

---------------------- Page: 10 ----------------------
62386-207 © IEC:2009 – 9 –


9.9 Detection of load decrease


If the actual LED load is significantly below the load measured during a successful “reference

measurement”, the gear may switch off the lamp if this is necessary for its safe operation. The

flag bit ‘load decrease’ is to be set.


9.10 Detection of load increase

If the actual LED load is significantly above the load measured during a successful “reference

measurement”, the gear may switch off if this is necessary for its safe operation. The flag bit

‘load increase’ is to be set.


9.11 Current protector
If the actual LED load of the control gear differs by more than a defined amount ΔP from the
load detected during the reference measurement, the current protector becomes active and
switches off the LED.
The current protector shall not become active until there has been a successful reference
measurement.
There are two possible situations in which the current protector becomes active:
– Overload: The actual LED load is higher than the load detected during the reference
measurement by at least ΔP.
– Underload: The actual LED load is lower than the load detected during the reference
measurement by at least ΔP.
The current protector shall become inactive either on mains voltage interruption or on receipt
of a command which causes the arc power level to be 0. If after switching on again, the
situation causing the current protector to become active still remains, the current protector
shall become active again.
The current protector can be enabled and disabled by the commands 225 “ENABLE
CURRENT PROTECTOR” and 226 “DISABLE CURRENT PROTECTOR”.
An active current protector shall become inactive upon reception of command 226 “DISABLE
CURRENT PROTECTOR”.
If the current protector is active, command 224 “REFERENCE SYSTEM POWER” shall be
ignored.

9.12 LED replacement on gear with load increase/decrease or current protector feature
If a LED is replaced with one of a different wattage without a new “REFERENCE SYSTEM
POWER” measurement being performed, the control gear shall detect a load increase or load
decrease as appropriate.
NOTE If a LED is replaced with one of the same wattage, the user should initiate a new ‘REFERENCE SYSTEM
POWER’ measurement only if this is recommended by the manufacturer.
9.13 Fast Fade Time
The Fast Fade Time is used instead of the Fade Time if the Fade Time is equal to 0. The Fast
Fade Time can be set to zero or to any value in the range “Min Fast Fade Time” to 27 as
defined in Table 1.
Programming the Fast Fade Time to 0 means “no fade” (change of light output as quickly as
possible).

11 Definition of commands


The requirements of Clause 11 of IEC 62386-102:2009 apply, except as follows:


11.3.1 Queries related to status information


Command 146: YAAA AAA1 1001 0010 “QUERY LAMP FAILURE”


Replacement:


Ask if there is a lamp problem at the given address. Answer shall be ‘Yes’ or ‘No’.

“Yes” means either open circuit or short circuit or load increase or load decrease or current
protector active.
“No” does not necessarily imply that no lamps have failed.
Command 153: YAAA AAA1 1001 1001 “QUERY DEVICE TYPE”
Replacement:
The answer shall be 6.
11.3.4 Application extended commands
Replacement:
Application extended commands shall be preceded by command 272
“ENABLE DEVICE TYPE 6”. For device types other than 6 these commands may be used in a
different way. A control gear for LED modules shall not react to application extended
commands preceded by command 272 “ENABLE DEVICE TYPE X” with X ≠ 6.
11.3.4.1 Application extended configuration commands
Every configuration command (224 to 228) shall be received a second time within 100 ms
before it is executed to reduce the probability of incorrect reception. No other commands
addressing the same control gear shall be sent between these two commands, otherwise the
first such command shall be ignored and the respective configuration sequence shall be
aborted.
Command 272 shall be sent before the two instances of the respective configuration

command, but not repeated between them (see Figure 1).

Command 224: YAAA AAA1 1110 0000 “REFERENCE SYSTEM POWER”

The control gear shall measure and store system power levels to detect load increase or load

decrease. This is an optional feature; it is up to the manufacturer to decide upon the number

of system power levels each type of gear should measure.


The measured power level shall be stored in the persistent memory. Commands received

during the measuring period shall be ignored except query commands and command 256.


After 15 min at most, the control gear shall finish the measurement process and shall go back

to normal operation. The measurement process shall be aborted if command 256

“TERMINATE” is received.

If the current protector is active this command shall be ignored. In this case, bit 7 ‘reference
measurement failed’ in the answer to command 241 “QUERY FAILURE STATUS”, shall be set
and command 249 “QUERY REFERENCE MEASUREMENT FAILED” shall be answered with
“Yes”.
Control gear without this feature shall not react (see command 240).
Command 225: YAAA AAA1 1110 0001 “ENABLE CURRENT PROTECTOR”
Enables the current protector of the control gear. The current protector can become active
after a successful reference measurement started by command 224.
The default configuration of the gear is “current protector enab
