Recommended measures or causes
LMV27: Optional press reset button >3 seconds.
Make a reset; if error occurs repeatedly, replace the LMV27
Make a reset; if error occurs repeatedly, replace the LMV27
Make a reset; if error occurs repeatedly, replace the LMV27
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 LMV27
No valid output
Adjust the curvepoints for all actuators
Check the external load controller, including the connection.
Parameters 123.1 and 123.2 must be identical (example: set to 1).
Check the external load controller, including the connection.
Parameters 123.1 and 123.2 must be identical (example: set to 1).
Check the external load controller, including the connection.
Parameters 123.1 and 123.2 must be identical (example: set to 1).
Check the external load controller, including the connection.
Parameters 123.1 and 123.2 must be identical (example: set to 1).
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 LMV27
LMV27 could not correct the difference in speed and reached a control range limit.
1. LMV27 is not standardized for this motor  repeat standardization.
Caution!
Settings of fuel-air ratio control must be checked!
2. Ramp time settings of the VSD are not shorter than those of the LMV27 (parameters 522,
523) or the setting for the modulating operating ramp is incorrect (parameter 544)
3. Characteristic of the VSD is not linear. Configuration of the voltage input at the VSD must
accord with that of the LMV27 (parameter 645).
