Pulse sequence and length at the speed
input were different from those antici-
pated
Fan was not able to keep the standard-
of VSD ized speed at a constant level
Air actuator has not reached the pre-
of Air Actuator purge position. For this reason, speed
standardization is not possible

Meaning for the LMV5x system Troubleshooting
Check to see if sensor disk and speed sensor are correctly
mounted.
Check if the distance of the inductive sensor is correct.
Check if the inductive sensor is correctly connected
Check if motor runs.
Check if the inductive sensor is correctly connected.
Check if distance of inductive sensor is correct
Check to see if all air-influencing actuators travel to the pre-
purge position.
Check to see if the relevant actuators are mechanically over-
loaded or replace defective actuator, if necessary.
Check power supply to the actuators
