IEC 62386-216:2018 pdf download.Digital addressable lighting interface – Part 216: Particular requirements for control gear – Load referencing (device type 15)
1 Scope
This part of IEC 62386 specifies a bus system for control by digital signals of electronic lighting equipment which is in line with the requirements of IEC 61 347 (all parts), with the addition of DC supplies. This document is only applicable to IEC 62386-1 02:201 4 and IEC 62386-1 02:201 4/AMD1 :— control gear that implements load referencing. NOTE Requirements for testing individual products during production are not included.

4 General
4.1 General The requirements of IEC 62386-1 02:201 4 and IEC 62386-1 02:201 4/AMD1 :—, Clause 4 apply, with the restrictions, changes and additions identified below. 4.2 Version number In 4.2 of IEC 62386-1 02:201 4 and IEC 62386-1 02:201 4/AMD1 :—, 1 02 shall be replaced by “21 6”, “version number” shall be replaced by “extended version number” and “versionNumber” shall be replaced by “extendedVersionNumber”.
9 Method of operation
9.1 General The requirements of IEC 62386-1 02:201 4 and IEC 62386-1 02:201 4/AMD1 :—, Clause 9 apply with the following additions.These limits are manufacturer specific. The manual/documentation shall state the following: • output levels used for reference measurement (reference levels), and • minimum and maximum levels considered not to be a load deviation or the calculation method for minimum and maximum levels based on the reference level. These levels shall be used for testing purposes. 9.3 Load referencing Load referencing is a manufacturer specific method to determine the normal operating range of the currently connected load in order to detect and notify load deviations. In order to perform load referencing, a series of reference measurements (R n ) are done at different output levels (L n ). The reference measurement can be done on load current, voltage or on any other derived physical quantity (e.g. power). The measurements shall be stored in NVM. After successful reference measurements have been done, load deviation can be detected. Execution of command “REFERENCE SYSTEM POWER” shall: • stop a running fade; • start or prolong load referencing; • when starting the load referencing: set “referenceMeasurementFailed” to TRUE to disable the load deviation detection, then set “loadDeviation” and “lampFailure” to FALSE. During load referencing: • the answer to query “QUERY REFERENCE RUNNING” shall be YES; • “loadDeviation” status shall not be changed; • the light output may be at any level between off and 1 00 %, “minLevel” and “maxLevel” as well as “actualLevel” being temporarily ignored. After the load referencing is finished or aborted the light output shall be adjusted as quickly as possible to reflect “actualLevel”; • lamp failure detection may be temporary inactive until the first reference measurement is completed. Load referencing shall be active for at least 500 ms.
