Any # Internal error - backup / restore
An error occurred while attempting to perform a backup or restore via parameter 050. See
diagnostic codes for more information.
157 (-99) Restore - ok, but backup < data set of
current system
No fault: Restore was successful, but the backup data record is smaller than in the current
system.
239 (-17) Backup - storage of backup in AZL23
faulty
Reset the fault and repeat the backup.
240 (-16) Restore - no backup in AZL23
There is no parameter set stored in the AZL23, so the restore process could not be
completed. Reset the fault.
241 (-15) Restore - abortion due to unsuitable
product no. (ASN)
The parameter set stored in the AZL23 has an unsuitable product no. (ASN), so the restore
process was aborted. Reset the fault.
242 (-14) Backup - backup made is inconsistent
The backed up parameter set is faulty and cannot be transferred back to the LMV3. Reset
the fault.
243 (-13) Backup - data comparison between µCs
faulty
Reset the fault and repeat the backup.
244 (-12) Backup data are incompatible
The parameter set stored in the AZL23 is not compatible with the LMV3 software version,
so the restore could not be completed. Reset the fault.
245 (-11) Access error to parameter
Restore_Complete
Reset the fault and repeat the restore.
246 (-10) Restore - timeout when storing in
EEPROM
Reset the fault and repeat the restore.
247 (-9) Data received are inconsistent
Some data in the parameter set stored in the AZL23 is invalid, so the restore could not be
completed. Reset the fault.
248 (-8) Restore cannot at present be made Reset the fault and repeat the restore.
249 (-7) Restore - abortion due to unsuitable
burner identification
The parameter set stored in the AZL23 has an unsuitable burner identification and must not
be transferred to the LMV3. Reset the fault and do not attempt the restore again.
250 (-6) Backup - CRC of one page is not correct The restore was not possible because the backup data record is invalid. Reset the fault.
251 (-5) Backup - burner identification is not
defined
A valid burner ID (parameter 113) is required to perform a backup. Set the burner ID, reset
the fault, and start the backup again.
252 (-4) After restore, pages still on ABORT Reset the fault and repeat the restore.
253 (-3) Restore cannot at present be made Reset the fault and repeat the restore.
254 (-2) Abortion due to transmission error Reset the fault and repeat the restore.
255 (-1) Abortion due to timeout during backup /
restore
Communication between the LMV3 and AZL23 was interrupted during the backup or
restore. Re-establish communication and reset the fault. If the fault continues, it is
possible the AZL23 is too old and does not support the backup / restore functions. If this is
the case, replace the AZL23.
146
Any # Timeout building automation interface
Modbus communication has been interrupted for longer than the setting of parameter 142.
Re-establish communication, then reset the fault.
