configuration parameters. Check
the prestage and spool valve
unit.
Position calibration takes too
long time due to weak
controllability.
Check assembly and assembly
related parameters and start
calibration again.
Supply pressure out of range
during position calibration.
Sensor failure (valve position/
spool position) is detected
during position calibration.
Valve position out of range is
detected during position
calibration.
