Meaning of the REC 27.100A2 system
Blocked upon irregularity
Contact request internal error
Voltage monitoring test internal error
Low level of power supply
Reset power supply voltage
Mains voltage supervision internal error
Control box meter internal error
Life cycle of the control box in the critical interval
(250,000 Start ups)
Life cycle of the control box exceeded
Interruption of fuel limiting meter input
EEPROM access internal error
EEPROM reading access internal error
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

Recommended measures
Can be caused by capacitive loads or presence of DC voltage
on the main power supply of the control box. The diagnostic
code indicates the input in which the problem arose
Carry out a reset; if the error arises repeatedly, replace the
control box
Carry out a reset; if the error arises repeatedly, replace the
control box
Insufficient mains voltage.
Conversion of the diagnostic code
Voltage value (230 V AC : 1.683)
Error code for the carrying out of a reset in the event of power
supply restoration (absence of error)
Carry out a reset; if the error arises repeatedly, replace the
control box
The envisaged life cycle of the control box has been exceeded.
Replace it.
The switch-off threshold has been reached.
Too many disturbance impulses on the input of the fuel meter.
Improve the electromagnetic compatibility.
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 control box.
Carry out a reset, repeat and check the last setting of the
parameters. If the error arises repeatedly, replace the control
box.

Carry out a reset, repeat and check the last setting of the
parameters. If the error arises repeatedly, replace the control
box.
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
