Display message Description
PRESTAGE CUT ERROR Prestage wire is cut or
connector is loose.
PRESSURE SENSOR 1
FAILURE
Actuator pressure sensor has
failed. The device
performance level is reduced.
Change the ND9000 device to
a new one during next
maintenance activity.
PRESSURE SENSOR 2
FAILURE
Actuator pressure sensor has
failed. The device
performance level is reduced.
Change the ND9000 device to
a new one during next
maintenance activity.
PRESSURE SENSOR 3
FAILURE
Supply pressure sensor has
failed. This does not affect
the performance level.
SPOOL VALVE SENSOR
FAILURE
Spool valve sensor failed.
Check the sensor
connections. The device
performance level is reduced.
Change the ND9000 device to
a new one during next
maintenance activity.
TEMPERATURE SENSOR
FAILURE
Temperature measurement
failed. The accuracy of the
measurements is reduced.
Change the ND9000 device
to a new one during next
maintenance activity.
STATISTICS DATABASE
ERROR
Failed to store statistics. New
measurements will be lost.
EVENT DATABASE ERROR Failed to store events. The
new events will be lost.
POSITION CALIBRATION
FAILED
Travel calibration failed.
Check the configuration
parameters and controller
mounting. Check that the
controller shaft is correctly
aligned.
TUNING FAILED Tuning procedure failed.
Check that the valve is
moving properly. Check the
prestage and spool valve
unit.
POSITION SENSOR RANGE
ERROR
Position sensor range failed
during calibration. Valve
controller shaft failed to
rotate minimum 45 degrees.
Check the configuration
parameters and controller
mounting. Check that the
controller shaft is correctly
aligned.
CALIBRATION TIMEOUT Calibration timeout occurred.
Check configuration and
installation.
CALIBRATION START
FAILED
The calibration starting
conditions are not met.
Check the supply pressure.
TUNING RANGE ERROR Tuning procedure failed.
Check the prestage and
spool valve unit.
