Recommended measures
Carry out a reset; if the error arises repeatedly, replace the unit
Carry out a reset; if the error arises repeatedly, replace the control box
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
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.
