IEC 62386-203:2009 pdf download – Digital addressable lighting interface – Part 203: Particular requirements for control gear – Discharge lamps (excluding fluorescent lamps) (device type 2)
1 Scope
This International Standard specifies a protocol and test procedures for the control of electronic control gear by digital signals used on a.c. or d.c. supplies, associated with discharge lamps (excluding fluorescent lamps).
NOTE Tests in this standard are type tests. Requirements for testing individual control gear during production are not included.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in Clause 3 of IEC 62386- 1 01 :2009 and Clause 3 of IEC 62386-1 02:2009 apply, with the following additional terms and definitions.
3.1
lamp cycling
periodic igniting and extinguishing of the lamp
3.2
lamp failure
lamp parameter outside of the tolerances for the normal lamp operation
NOTE The number of attempts to ignite the lamp parameter before final switching off is control gear dependent.
3.3
run-up time
time which the system of control gear and lamp(s) needs to set the lamp output power to its nominal lamp power value after switching on the lamp
3.4
waiting for ignition
control gear status with ignition function maximal up to the ignition time out without lamp ignition
3.5
ignition time out
status of the control gear after an inefficient ignition time
NOTE The time is specified by the control gear manufacturer.
3.6
arc power at requested value
lamp(s) status with the requested arc power
4 General
The requirements of Clause 4 of IEC 62386-1 01 :2009 and Clause 4 of IEC 62386-1 02:2009 apply.
5 Electrical specifications
The requirements of Clause 5 of IEC 62386-1 01 :2009 and Clause 5 of IEC 62386-1 02:2009 apply.
6 Interface power supply
The requirements of Clause 6 of IEC 62386-1 01 :2009 and Clause 6 of IEC 62386-1 02:2009 apply, if a power supply is integrated with the control gear.
7 Transmission protocol structure
The requirements of Clause 7 of IEC 62386-1 01 :2009 and Clause 7 of IEC 62386-1 02:2009 apply.
8 Timing
The requirements of Clause 8 of IEC 62386-1 01 :2009 and Clause 8 of IEC 62386-1 02:2009 apply.
9 Method of operation
The requirements of Clause 9 of IEC 62386-1 01 :2009 and Clause 9 of IEC 62386-1 02:2009 apply with the following exceptions:
Addition to Clause 9 of IEC 62386-102:2009:
9.9 Arc power at requested value versus fade running
If a new arc power level is requested from a stable arc power level situation, the “Fade Running” bit indicates fading from the stable arc power level to the newly requested power level.
If the fading has been finished and the new arc power level has been reached the “Arc Power At Requested Value” bit indicates whether the arc power is also at the desired value.

10 Declaration of variables
The requirements of Clause 1 0 of IEC 62386-1 02:2009 apply, with the following declaration of additional variables, given in Table 1 .
11 Definition of commands The requirements of Clause 1 1 of IEC 62386-1 01 :2009 and Clause 1 1 of IEC 62386-1 02:2009 apply, with the following exceptions: Amendment of Clause 11 of IEC 62386-102:2009:
11 .3.4 Application extended commands Replacement:
11 .3.4.1 General Every control command (224) and configuration command (240) shall be received a second time within 1 00 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. Command 272 shall be received before the two instances of the application extended configuration/control command, but not between them (see Figure 2).
