FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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.
International Standard IEC 62386-208 has been prepared by subcommittee 34C: Auxiliaries

INTRODUCTION
This first edition of IEC 62386-208 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 recognized.
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 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 208.
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".

3 Terms and definitions
For the purposes of this document, the terms and definitions given in Clause 3 of
IEC 62386-101:2009 and Clause 3 of IEC 62386-102:2009 shall apply, with the following
additional definitions.
3.1
virtual arc power level
value calculated by the control gear during virtual dimming. It corresponds to the actual level
of a dimmable control gear
3.2
virtual dimming
attribute of the control gear for treating arc power commands in the same way as a dimmable
control gear. It provides virtual dimming by calculating a virtual arc power level in accordance
with the appropriate fading definition, thus requiring the output state to change when the
virtual arc power level reaches or passes a threshold
3.3
up switch-on threshold
value against which the virtual arc power level is continually compared, the output of the
control gear being switched on whenever the virtual arc power level reaches or passes this
level whilst increasing
3.4
up switch-off threshold
value against which the virtual arc power level is continually compared, the output of the
control gear being switched off whenever the virtual arc power level reaches or passes this
level whilst increasing
62386-208 © IEC:2009 – 9 –
3.5
down switch-on threshold
value against which the virtual arc power level is continually compared, the output of the
control gear being switched on whenever the virtual arc power level reaches or passes this
level whilst decreasing
3.6
down switch-off threshold
value against which the virtual arc power level is continually compared, the output of the
control gear being switched off whenever the virtual arc power level reaches or passes this
level whilst decreasing
4 General description
The requirements of Clause 4 of IEC 62386-101:2009 and Clause 4 of IEC 62386-102:2009
shall apply.
5 Electrical specification
The requirements of Clause 5 of IEC 62386-101:2009 and Clause 5 of IEC 62386-102:2009
shall apply.
6 Interface power supply
The requirements of Clause 6 of IEC 62386-101:2009 and Clause 6 of IEC 62386-102:2009
shall apply if a power supply unit is integrated into the switching control gear.
7 Transmission protocol structure
The requirements of Clause 7 of IEC 62386-101:2009 and Clause 7 of IEC 62386-102:2009
shall apply.
8 Timing
The requirements of Clause 8 of IEC 62386-101:2009 and Clause 8 of IEC 62386-102:2009
shall apply.
9 Method of operation
The requirements of Clause 9 of IEC 62386-101:2009 and Clause 9 of IEC 62386-102:2009
shall apply with the following exceptions:
Amendments to Clause 9 of IEC 62386-102:2009:
9.2 Power-On
Addition:
If no command affecting power level is received before 0,6 s after mains power-on, the control
gear shall set the virtual arc power level (VAPL) to the POWER-ON LEVEL immediately
without fading.
– 10 – 62386-208 © IEC:2009
In this case the VAPL shall be compared against the two up-threshold parameters to
determine the output state. If the output state cannot be determined because the VAPL is
below the thresholds, then the output shall be switched off, unless the UP Switch-On
Threshold is set to “MASK”, in which case the output shall be switched on.
If “MASK” is stored as the POWER ON LEVEL the VAPL shall be set to the last VAPL before
mains power-down and the output state shall be determined according to the last threshold
reached or passed (as indicated by bits 2 and 3 of the SWITCH STATUS byte).
9.3 Interface-failure
Addition:
If "MASK" is stored as SYSTEM FAILURE LEVEL, the control gear shall stay in the state it is
in (no change of the virtual arc power level, no switching on or off). If any other value is
stored, the control gear shall go to this virtual arc power level immediately without fading. On
restoration of the idle voltage the control gear shall not change its state.
NOTE The actual output state will also depend on the dim direction. This has to be considered in some threshold
configurations (e.g. switching hysteresis).
9.4 Min and max level
Addition:
The MIN LEVEL and the MAX LEVEL are used to define the range of virtual dimming:
The control gear shall check each received Arc Power Level against the MIN LEVEL and the
MAX LEVEL before virtual dimming is performed.
Programming a MIN LEVEL above or a MAX LEVEL below the virtual arc power level shall set
the virtual arc power level to the new MIN LEVEL or MAX LEVEL immediately without fading.
If this causes the virtual arc power level to reach or pass a threshold, the output state shall
change accordingly.
Programming a MIN LEVEL below or a MAX LEVEL above the virtual arc power level shall not
be affecting the virtual arc power level.
Arc power levels stored in the control gear shall not be restricted by the MIN and MAX LEVEL
settings. Nevertheless, those levels shall cause the virtual arc power level to be set to the
MIN LEVEL or MAX LEVEL if the stored value is below the MIN LEVEL or above the
MAX LEVEL.
The arc power levels "0" (OFF) and "255" (MASK) shall not be affected by the MIN and
MAX LEVEL settings.
If the control gear does not support programmable thresholds the MIN LEVEL and the MAX
LEVEL are fixed at the default values.
Additional subclause:
9.9 Switching characteristics
Different switching characteristics can be achieved by programming the parameters UP
SWITCH-ON THRESHOLD, UP SWITCH-OFF THRESHOLD, DOWN SWITCH-ON
THRESHOLD and DOWN SWITCH-OFF THRESHOLD.
62386-208 © IEC:2009 – 11 –
The control gear shall continually compare the virtual arc power level (VAPL) against the four
threshold parameters. The output shall be switched on or off in accordance with the result of
the comparison and the current direction of dimming (see Table 1).
Table 1 – virtual arc power level (VAPL)
Dimming direction Result of comparison Action
(virtual)
Up Switch the output on
VAPL ≥ up switch-on threshold
Up VAPL ≥ up switch-off threshold Switch the output off
Down Switch the output on
VAPL ≤ down switch-on threshold
Down Switch the output off
VAPL ≤ down switch-off threshold
A threshold with the value ‘MASK’ shall not be used for the comparison.
If a pair of thresholds (“up-pair” or “down-pair”) is programmed to the same value, switching
on takes priority.
Programming a threshold shall not initiate a comparison and the output shall remain
unchanged.
If the control gear does not support programmable thresholds, the thresholds are fixed at the
default values.
Figure 1 gives an example of a possible configuration. More examples can be found in Annex
A.

11 Definition of commands
The requirements of Clause 11 of IEC 62386-101:2009 and Clause 11 of IEC 62386-
102:2009, shall apply with the following exceptions:
11.1 Arc power control commands
Addition:
For all arc power control commands the following rule applies: Actual Arc Power Level =
virtual arc power level.
A received arc power control command shall affect the virtual arc power level.
Whenever the definition of an arc power control command requires the lamp (load) to be
switched off, the virtual arc power level shall be set to 0. If the virtual arc power level is 0 and
command 8 “ON AND STEP UP” is received, the virtual arc power level shall be set to MIN
LEVEL.
The Actual Arc Power Level (and so the output state) shall only change when the virtual arc
power level reaches, passes or leaves a threshold.
11.2.1 General configuration commands
Amendment:
62386-208 © IEC:2009 – 13 –
Command 33: YAAA AAA1 0010 0001 "STORE ACTUAL LEVEL IN THE DTR"
Store virtual arc power level in the DTR.
11.3.1 Queries related to status information
Amendment
Command 144: YAAA AAA1 1001 0000 "QUERY STATUS"
Bit 4 “Fade running” shall be set during a virtual dimming process.
Command 153: YAAA AAA1 1001 1001 "QUERY DEVICE TYPE"
The answer shall be 7.
11.3.2 Queries related to arc power parameter settings
Amendment:
Command 160: YAAA AAA1 1010 0000 "QUERY ACTUAL LEVEL"
The answer shall be “0” if the load is switched off or “254” if the load is switched on. During
preheating (if applicable) or if a load error is detected the answer shall be "MASK".
11.3.4 Application extended commands
Replacement:
Application extended commands shall be preceded by command 272 ‘ENABLE DEVICE TYPE
7’.
NOTE For device types other than 7, these commands may be used in a different way.
A switching control gear with only switching function shall not react to application extended
commands preceded by command 272 ‘ENABLE DEVICE TYPE X’ with X ≠ 7.
11.3.4.1 Application extended configuration commands
Every configuration command (224 – 239) 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
configuration sequence aborted.
Command 272 must be sent before the two instances of the respective configuration
command, but not repeated between them (see Figure 2).

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 Clause 10.

Command 224: YAAA AAA1 1110 0000 ‘REFERENCE SYSTEM POWER’
The switching control gear shall measure and store the system power level in order to detect
load errors. 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 switching 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’.
This is an optional feature. Control gear without this feature shall not react (see command
240) and bit 7 in the FAILURE STATUS shall be always being zero.
Command 225: YAAA AAA1 1110 0001 ‘STORE DTR AS UP SWITCH-ON
THRESHOLD’
Store the content of the DTR as new UP SWITCH-ON THRESHOLD.
If 255 (‘MASK’) is stored, the threshold shall not be used for comparison.
This is an optional feature. Switching control gear without this feature shall not react.
Command 226: YAAA AAA1 1110 0010 ‘STORE DTR AS UP SWITCH-OFF
THRESHOLD’
Store the content of the DTR as new UP SWITCH-OFF THRESHOLD.
If 255 (‘MASK’) is stored, the threshold shall not be used for comparison.
This is an optional feature. Switching control gear without this feature shall not react.
Command 227: YAAA AAA1 1110 0011 ‘STORE DTR AS DOWN SWITCH-ON
THRESHOLD’
Store the content of the DTR as new DOWN SWITCH-ON THRESHOLD.
If 255 (‘MASK’) is stored, the threshold shall not be used for comparison.
This is an optional feature. Switching control gear without this feature shall not react.
Command 228: YAAA AAA1 1110 0100 ‘STORE DTR AS DOWN SWITCH-OFF
THRESHOLD’
Store the content of the DTR as new DOWN SWITCH-OFF THRESHOLD.
If 255 (‘MASK’) is stored, the threshold shall not be used for comparison.
This is an optional feature. Switching control gear without this feature shall not react.
Command 229: YAAA AAA1 1110 0101 ‘STORE DTR AS ERROR HOLD-OFF
TIME’
Store the content of the DTR as new ERROR HOLD-OFF TIME value in units of 10 s.
The ERROR HOLD-OFF TIME specifies the minimum time an error must be continuously
present in order to be indicated.
62386-208 © IEC:2009 – 15 –
If 0 is stored, a load error shall be indicated immediately.
If 255 ('MASK') is stored, a load error shall not be indicated.
This is an optional feature. Switching control gear without this feature shall not react.
Commands 230 – 231: YAAA AAA1 1110 011X
Reserved for future needs. The switching control gear must not react in any way.
