Faults - Possible causes - Solutions
Meaning of the REC 27 ...system
EEPROM writing access internal error
EEPROM access internal error
EEPROM access internal error - synchronisation
during the initialisation
EEPROM access internal error – command
synchronisation
EEPROM access internal error - time-out
EEPROM access internal error - page interrupted
EEPROM register initialisation internal error
EEPROM access internal error – request
synchronisation
Restoration started
Internal error – backup / restoration
Restoration – OK, but backup < compared with set data of
current system
Backup - logging of the backup on RDI21... failed
Reset - no backup in RDI21...
Reset - Interruptions relating to impracticable ASN
Backup – the backup carried out is contradictory
Backup – the data comparison between the internal
microprocessors is irregular
The backup data are incompatible
Error in access to the parameter Restore_Complete
Restoration – time-out during logging in EEPROM
The data received are contradictory
The restoration cannot currently be carried out
Restoration – interruption caused by inadequate
identification of the burner
Backup – the CRC of a page is not correct
Backup – the identification of the burner is not defined
After restoration, the pages are still in
INTERRUPTION
The restoration cannot currently be carried out
Interruption owing to transmission error
Interruption owing to time-out during the restoration
Time-out of the system automation interface
Modbus time-out
TÜV test
Invalid phase
60
Recommended measures
Carry out a reset, repeat and check the last setting of the
parameters. If the error arises repeatedly, replace the flame
control.
Carry out a reset, repeat and check the last setting of the
parameters. Restore the group of parameters: if the error arises
repeatedly, replace the flame control.
Carry out a reset; If the error arises repeatedly, replace the
flame control.
Carry out a reset, repeat and check the last setting of the
parameters. If the error arises repeatedly, replace the flame
control.
Carry out a reset, repeat and check the last setting of the
parameters. If the error arises repeatedly, replace the flame
control.
Carry out a reset, repeat and check the last setting of the
parameters. If the error arises repeatedly, replace the flame
control.
Carry out a reset; if the error arises repeatedly, replace the
flame control.
Carry out a reset, repeat and check the last setting of the
parameters. If the error arises repeatedly, replace the flame
control.
The restoration of a backup has been started (no error)
Restoration successful, but the backup data installed are fewer
than those currently present in the system.
Perform the reset and repeat backup
No backup in RDI21...
The backup has an impracticable ASN and cannot reset the
unit
The backup is irregular and cannot be transferred again
Repeat the reset and backup
The backup data are incompatible with the current version of
the software; the restoration is not possible
Repeat the reset and backup
Repeat the reset and backup
The series of backup data is not valid; restoration is not
possible
Repeat the reset and backup
The backup has an inadequate identification of the burner and
must not be transferred to the flame control
The series of backup data is not valid; restoration is not
possible
Define the identification of the burner and repeat the
backup
Repeat the reset and backup
Repeat the reset and backup
Repeat the reset and backup
Carry out a reset, check the connections and repeat the
backup
