30 Error code list
Remedy
function (manual interruption of 4...20 mA analog input)
No error - change to Fuel 0
No error - change to Fuel 1
Check wiring to see if there is an open-circuit

Note
Curves cannot be set
Make a reset; if error occurs repeatedly, replace the unit
Check wiring for short-circuit
Note

Curves cannot be set.
LMV36...: Optional press reset button >3 seconds.
Make a reset; if error occurs repeatedly, replace the unit
Make a reset; if error occurs repeatedly, replace the unit
No valid output
Adjust the curvepoints for all actuators
Parameterize the home position for all actuators used
Parameterize the prepurge position for all actuators used
Parameterize the postpurge position for all actuators used
Parameterize the ignition position for all actuators used
Make a reset; if error occurs repeatedly, replace the unit
No valid output
Adjust the curvepoints for all actuators
Can be caused by different standardized speeds (e.g. after restore of data set) when the VSD is
activated  standardize again and check adjustment of the fuel-air ratio control system
Make a reset; if error occurs repeatedly, replace the unit
Basic unit could not correct the difference in speed and reached a control range limit.
