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 62386-204 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 IEC 62386-200 series, in
referring to any of the clauses of IEC 62386-101 or IEC 62386-102, specifies 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 the
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 204.
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".

– 8 – 62386-204 © IEC:2009
9.9 Detection of load decrease
If the actual lamp 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 in such circumstances.
9.10 Detection of load increase
If the actual lamp load is significantly above 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 increase’ is to be set in such circumstances.
9.11 Current protector
If the actual lamp 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 lamp.
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 lamp load is higher than the load detected during the reference
measurement by at least ΔP.
– Underload: The actual lamp 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 pertains, 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 on reception of command 226 ‘DISABLE
CURRENT PROTECTOR’.
If the current protector is active command 224 ‘REFERENCE SYSTEM POWER’ shall be
ignored.
9.12 Lamp replacement on gear with load increase/decrease or current protector
feature
If a lamp is replaced with one of a different wattage without a new ‘REFERENCE SYSTEM
POWER’ measurement being performed, the gear shall detect a load increase or a load
decrease as appropriate.
NOTE If a lamp 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.
10 Declaration of variables
The requirements of Clause 10 of IEC 62386-101:2009 and Clause 10 of IEC 62386-102:2009
apply, with the following additional variables for this device type, as indicated in Table 1.

11.3.1 Queries related to status information
Amendment:
Command 146: YAAA AAA1 1001 0010 'QUERY LAMP FAILURE'
Asks 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'
Answer shall be 3.
11.3.4 Application extended commands
Replacement:
11.3.4.1 Application extended configuration commands
Every configuration command (224 – 226) shall be received a second time within 100 ms
(nominal) before it is executed in order 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 control or
configuration sequence shall be aborted.
– 10 – 62386-204 © IEC:2009
Command 272 shall be received before the two instances of the application extended
configuration command, but not between them (see Figure 1).

All values of DTR shall be checked against the values mentioned in Clause 10, Range of
validity, i.e. the value shall be set to the upper / lower limit if it is above / below the valid
range defined in Table 1.
Command 224: YAAA AAA1 1110 0000 ‘REFERENCE SYSTEM POWER’
Reference measurement is an optional feature, the presence of which is indicated in bits 2, 3
and 4 of the ‘FEATURES’ byte (see command 240). If all these bits are zero, then reference
measurement is not supported, and this command shall be ignored. Otherwise, on receipt of
this command, the control gear shall proceed as follows.
The control gear shall measure and store system power levels in order to detect load increase
or load decrease. 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.
When there has been no successful reference measurement or the most recent reference
measurement was unsuccessful, bit 7, reference measurement failed, in the answer to
command 240 ‘QUERY FAILURE STATUS’ shall be set and command 249 ‘QUERY
REFERENCE MEASUREMENT FAILED’ shall be answered with ‘Yes’.
If the current protector is active this command shall be ignored. In this case bit 7, reference
measurement failed, in the answer to command 240 ‘QUERY FAILURE STATUS’ shall be set
and command 249 ‘QUERY REFERENCE MEASUREMENT FAILED’ shall be answered with
‘Yes’.
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 ENABLED'. The status of
the current protector (enabled / disabled) shall be stored in the persistent memory of the
control gear.
The current protector is an optional feature. Control gear without this feature shall not react
(see command 240).
62386-204 © IEC:2009 – 11 –
Command 226: YAAA AAA1 1110 0010 'DISABLE CURRENT PROTECTOR'
Disables the current protector of the control gear.
The current protector is an optional feature. Control gear without this feature shall not react in
any way.
(see command 240).
Commands 227: YAAA AAA1 1110 0011
Reserved for future needs. The control gear shall not react in any way.
Commands 228-231: YAAA AAA1 1110 01XX
Reserved for future needs. The control gear shall not react in any way.
Commands 232-239: YAAA AAA1 1110 1XXX
Reserved for future needs. The control gear shall not react in any way.
11.3.4.2 Application extended query commands
Command 240: YAAA AAA1 1111 0000 ‘QUERY FEATURES’
The answer from the control gear shall be the following information about which optional
features and query commands are implemented.
bit 0 ‘1’ = short circuit detection can be queried
bit 1 ‘1’ = open circuit detection can be queried
bit 2 ‘1’ = detection of load decrease can be queried
bit 3 ‘1’ = detection of load increase can be queried
bit 4 ‘1’ = current protector is implemented and can be queried
bit 5 ‘1’ = thermal shut down can be queried
bit 6 ‘1’ = light level reduction due to thermal overload can be queried
bit 7 ‘1’ = physical selection supported
Bits 2, 3, 4. If any of these features is available, command 224 ‘REFERENCE SYSTEM
POWER’, command 249 ‘QUERY REFERENCE RUNNING’ and command 250 'QUERY
REFERENCE MEASUREMENT FAILED' are mandatory.
Bit 5; bit 6. A ‘thermal shut down’ or a ‘light level reduction due to thermal overload’ are not
interpreted as lamp failure; nevertheless the control gear shall answer ‘MASK’ to a ‘QUERY
ACTUAL LEVEL’.
NOTE The fact that a thermal overload protection is implemented, the actual status of which can be queried, does
not relieve the user from the obligation to comply with any safety-relevant information for installation given by the
manufacturer. A note to this effect should be included in the manual.
Command 241: YAAA AAA1 1111 0001 ‘QUERY FAILURE STATUS’
Answer is the following ‘FAILURE STATUS’ byte:
bit 0 short circuit ‘0’ = No
bit 1 open circuit ‘0’ = No
bit 2 load decrease ‘0’ = No
bit 3 load increase ‘0’ = No
bit 4 current protector active ‘0’ = No
bit 5 thermal shut down ‘0’ = No
bit 6 thermal overload with light level reduction ‘0’ = No
bit 7 reference measurement failed ‘0’ = No
– 12 – 62386-204 © IEC:2009
Bit 0, short circuit, means either a severe short circuit or a physical control gear overload
(> 100 % of nominal load).
If any of the bits 0 to 4 are set, the answer to command 146 'QUERY LAMP FAILURE' shall
be 'Yes' and bit 1 in the answer to command 144 'QUERY STATUS' shall be set.
If any of the back-channel bits 0, 1, 5 or 6 are set, the answer to command 160 'QUERY
ACTUAL LEVEL' shall be 'MASK'.
Bit 7 shall be set if the reference measurement of the system power failed for any reason, or if
there has been no reference measurement at all. It shall be stored in the persistent memory.
If the reference measurement is not supported, this bit shall always be ‘0’.
The ‘FAILURE STATUS’ byte shall be available in the RAM of the control gear and shall be
updated regularly by the control gear according to the actual situation. The bits shall not be
changed if the relevant situation cannot be checked.
