Burner ID offers the OEM the opportunity - which may also be the OEM's duty - to store
an individual burner ID in each LMV5... system by means of the OEM password, prior
to delivery.
Burner ID is then used to enable or disable the data transfer between the ba-
sic unit and the AZL5... backup storage. Parameters can be loaded to the
AZL5... at any time, if the burner ID in the basic unit is not in the «as sup-
plied» status.
The burner ID itself is part of the data transfer in both directions (if that is possible). In
addition, for the burner, the burner ID represents one of a number of start prerequisites.
In other words, the burner cannot be started up as long as the burner ID is in the «as
supplied» status. So, it is possible to have data transmission between the basic unit and
the AZL5... of one plant (burner IDs are identical) and between an AZL5... and a new
basic unit (burner ID «as supplied» by Siemens BT). Data transmission between
AZL5... and basic units of different plants (burner IDs not identical) is not possible (no
«cloning»!).
Invalid characters for the burner ID are all vowels (ä, ö, ü and ß).
Minimum length of burner ID = 4 characters
Maximum length of burner ID = 15 characters
The AZL5... can output the display texts in different languages.
Changeover to another language takes place via menu «Params & Display»
→ «AZL5...» → «Language».
In addition to English as the basic language, the AZL5... provides another 5 languages.
This means that a language group can comprise a maximum of 6 languages.
Using the program update function of the PC tool, additional language groups can be
loaded to the AZL5... together with the relevant program version.
Hence, direct exchange of the language without loading a new program version is not
possible.
The LMV5... system is equipped with a real time clock with a calendar and backup,
which is accommodated in the AZL5... .
The clock features automatic s ummer- / w intertime changeover.
The following parameter setting choices are available:
Parameter1 summer- / wintertime changeover:
Parameter2 summer- / wintertime changeover:

Changeover takes place on the dates given above in the night between 02:00 and 03:00
hrs. The time shift is always 1 hour.
Changeover takes place only if the AZL5... receives power at that moment in time.
Backup is about 10 years.
The backup battery is a replaceable lithium battery.
Refer to «Technical data».
When changing batteries, ensure ESD protection!
If the AZL5... uses the associated interface to communicate with a building management
center, the latter can act as the clock master by transmitting cyclically a preset time of
day and date to the AZL5... .
This information is given priority over all other time of day / date sources.
