4 Alert identifiers
4.1 Requirements
When defining alerts listed in Annex A, the corresponding alert identifiers defined in Annex A shall be used.
Alerts not listed in Annex A shall be assigned an alert identifier in the range 10000 to 9999999.
The manufacturer shall provide a list of all alerts in the EUT, together with their assigned alert identifiers.
4.2 Method of test and required results
Confirm by inspection of manufacturer’s documentation that:
• if the manufacturer has defined alerts listed in Annex A, the corresponding alert identifiers are assigned as specified in Annex A; and
• if the manufacturer has defined alerts not listed in Annex A, the corresponding alert identifiers are assigned within the range 10000 to 9999999.
If applicable, cause up to 5 alerts listed in Annex A and confirm by observation that the reported ALF messages are indicating the appropriate identifier.
If applicable, cause up to 10 alerts not listed in Annex A and confirm by observation that the reported ALF messages are indicating an identifier in the range 10000 to 9999999.
5 Reserved cluster identifiers
5.1 Requirements
When defining clusters (see IEC 62923-1), the cluster identifiers defined in Annex B shall be used for their intended purpose. Only when the cluster identifiers defined in Annex B are not applicable, the free range of cluster identifiers as defined in IEC 62923-1 shall be used.
The manufacturer shall provide a list of all alerts in the EUT, together with their assigned cluster identifiers.
5.2 Method of test and required results
Confirm by inspection of manufacturer’s documentation that cluster identifiers are used as specified in Annex B. If the clusters defined in Annex B are not applicable, confirm by inspection that the cluster identifiers are used in the free range of cluster identifiers as defined in lEG 62923-1.IEC 62923-2 pdf download.
