Blocked upon irregularity
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
106 - 108 # Contact request internal error Carry out a reset; if the error arises repeatedly, replace the control box
110 # Voltage monitoring test internal error Carry out a reset; if the error arises repeatedly, replace the control box
111 0 Low level of power supply Insufficient mains voltage
112 0 Reset power supply voltage
Error code for the carrying out of a reset in the event of power supply restoration
(absence of error)
113 # Mains voltage supervision internal error Carry out a reset; if the error arises repeatedly, replace the control box
115 # Control box meter internal error
116 0 Life cycle of the control box in the critical interval The envisaged life cycle of the control box has been exceeded. Replace it.
117 0 Life cycle of the control box exceeded The switch-off threshold has been reached.
120 0 Interruption of fuel limiting meter input
Too many disturbance impulses on the input of the fuel meter.
Improve the electromagnetic compatibility.
121 - 124 # EEPROM access internal error
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
125 # EEPROM reading access internal error
Carry out a reset, repeat and check the last setting of the parameters. If the error
arises repeatedly, replace the control box
126 # EEPROM writing access internal error
Carry out a reset, repeat and check the last setting of the parameters. If the error
arises repeatedly, replace the control box
127 # EEPROM access internal error
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
128 0
EEPROM access internal error - synchronisation
during the initialisation
Carry out a reset; If the error arises repeatedly, replace the control box
129 #
EEPROM access internal error – command
synchronisation
Carry out a reset, repeat and check the last setting of the parameters. If the error
arises repeatedly, replace the control box
130 # EEPROM access internal error - time-out
Carry out a reset, repeat and check the last setting of the parameters. If the error
arises repeatedly, replace the control box
131 # EEPROM access internal error - page interrupted
Carry out a reset, repeat and check the last setting of the parameters. If the error
arises repeatedly, replace the control box
132 # EEPROM register initialisation internal error Carry out a reset; If the error arises repeatedly, replace the control box
133 - 135 #
EEPROM access internal error – request
synchronisation
Carry out a reset, repeat and check the last setting of the parameters. If the error
arises repeatedly, replace the control box
136 1 Restoration started The restoration of a backup has been started (no error)
