direction and other information used for proper diagnostics.
If no friction calibration is performed, the positioner will
soon determine the operating friction, but other diagnostic
information will be missing.
Possible Solutions: Perform a Friction Calibration using the
display menu, handheld, or Sensor Calibration page of the
DTM. See the Calibration section of the IOM for warnings.

PARTIAL STROKE TEST SCHEDULED
Description: The schedule established by the user shows
that a partial stroke test is due.
Possible Solutions: Follow internal procedures to initiate a
partial stroke test (PST). A partial stroke test will cause the
valve to move suddenly and the positioner will not respond
to commands while the PST is in progress. See the Partial
Stroke Test page of the DTM to verify PST settings.

STROKE
TEST
IN
PROGRESS
Description: The positioner is in Out Of Service (OOS)
mode because a test or signature has been initiated.
These include Step Test, Ramp Test, or Partial Stroke
Test.
Possible Solutions: Signatures and tests can be defined,
initiated, and cancelled through the Off-Line Diagnostics
pages of the DTM.

STROKE CALIBRATION IN PROGRESS
SETTING INNER LOOP OFFSET
PRESSURE CALIBRATION IN PROGRESS
FRICTION CALIBRATION IN PROGRESS
ANALOG OUTPUT CALIBRATION IN PROGRESS
COMMAND INPUT CALIBRATION IN PROGRESS
Description: A calibration sequence is in progress. The
inner loop offset is an important step of the stroke
calibration.
Possible Solutions: The calibration can be canceled from
the corresponding calibration page of the DTM, from the
handheld, or by briefly pressing the BACK button.

DI COMMAND OVERRIDE
Description: The Multi-Function Card has been configured
as a Discrete Input (DI) and to override the input command,
positioning the valve at a preconfigured set point. The DI
signal is active and the positioner is attempting to control
the valve at the set point.
Possible Solutions: Configure the DI function and set point
using the menu, a handheld or the Multi-Function Card
Configuration page of the DTM.

JOG COMMAND MODE
Description: The positioner has been placed in a local
override mode where the valve can only be stroked using
the UP and DOWN buttons. The positioner will not
respond to analog or digital input commands from HART.
Possible Solutions: Control the valve using the UP and
DOWN buttons. This mode may be cancelled by briefly
pushing the QUICK-CAL/ACCEPT button.

JOG CALIBRATION SET 100% POSITION
Description: During a jog calibration, the unit is waiting for
the user to manually adjust the valve position to the desired
100% open position.
Possible Solutions: Use the Up and Down buttons on the
positioner to adjust the valve to the desired fully open
position. The QUICK-CAL/ACCEPT button to accept.

POSITION HIGH LIMIT ALERT
POSITION LOW LIMIT ALERT
Description: The position has reached or is exceeding a
user defined position limit. This is similar to a limit switch
indicator.
Possible Solutions: Set the limit to a higher (or lower) value
if more travel is needed, or adjust the command signal
back in the specified range.

PILOT RELAY TRAVEL WARNING
VALVE CYCLES WARNING
VALVE TRAVEL WARNING
Description: The cycle or travel limit of the valve, actuator,
bellows or pilot relay has been exceeded. Each cycle
represents two reversals of the direction of valve
movement. The cycle counting criterion and count limit (for
the valve, actuator and bellows) are set by the user to track
the usage of the valve assembly.
Possible
Solutions:
Follow
routine
procedures
for
maintenance when the limit is reached. For example valve
inspection may include checking the packing tightness, and
