FRICTION CALIBRATION REQUIRED
Description: No friction calibration has been performed since the last
factory reset. The friction calibration determines a preliminary friction
value, spring forces and direction and other information used for
proper diagnostics. If no friction calibration is performed, the posi-
tioner 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 Cali-
bration 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.

SIGNATURE OR PARTIAL 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 corre-
sponding 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.
