28.3 Status Code Descriptions
NOTE:
Not all status codes are available with all
positioner models.

POWER ON
Description: No issues.
Possible Solutions: Not applicable.
GGGY

TIGHT SHUT OFF MODE
Description: (Also called MPC.) The Final Command is
beyond the user set limit for the tight shutoff feature and
the positioner is applying full actuator pressure to close (or
open) the valve. This is a normal condition for all valves
when closed. The factory default setting triggers this at
command signals below 1%. This indication may also
occur on 3 way valves at both ends of travel if the upper
Tight Shut Off value has been set.
Possible Solutions: If tight shutoff is not desired reset the
tight shutoff limits or adjust the command signal inside of
the specified Tight Shut Off values.

LOCAL INTERFACE OFF
Description: Control and configuration features are locked
at the positioner's local interface. This is to prevent
unauthorized or accidental adjustments. The buttons can
still be used to view information on the LCD. The status
code is only present for a short time when the user
attempts to make a change through the display menu.
Possible Solutions: The DTM's Local Interface page is used
to unlock the local interface, turn this feature on and off,
and to set the PIN. For temporary access, a Personal
Identification Number (PIN) can be entered from the
positioner if an LCD is installed.

DIGITAL COMMAND MODE
Description: The input command is set by a digital HART
command instead of the 4-20 mA signal.
Possible Solutions: The input command source can be
changed back to the 4-20 mA signal by using a handheld,
the Dashboard page of the DTM, or performing a manual
Command Reset. Perform the Command Reset by
holding both the UP and DOWN buttons and briefly
pressing the QUICK-CAL/ACCEPT button.

INITIALIZING
Description: The positioner has powered up and is
displaying a blink sequence 3 times.
Possible Solutions: Wait for 3 blink sequences to complete.

SQUAWK MODE
Description: A user has set the positioner to flash a special
sequence so that it can be visually located.
Possible Solutions: This mode is cancelled if one of the
following occurs: 1) The QUICK-CAL/ACCEPT button is
briefly pressed. 2) The Squawk mode is turned off
remotely. 3) More than one hour has passed since the
command was issued.

SOFT STOP HIGH LIMIT ALERT
SOFT STOP LOW LIMIT ALERT
Description: The Final Command would move the valve
beyond the user-set Soft Limit, but the internal software is
holding the position at the limit. The function is similar to a
mechanical limit stop except it is not active if the unit is un-
powered.
Possible Solutions: If more travel is needed, reset the Soft
Limits. If not, adjust the Final Command signal back into
the specified range.

PRESSURE CALIBRATION REQUIRED
Description: A Factory Pressure Calibration has not been
performed. Unlike a regular pressure sensor calibration, a
Factory Pressure Calibration saves the calibration values to
memory, making them available should a factory reset be
performed. Proper pressure sensor calibration is required
for proper pressure sensing and diagnostics. Calibration
values from a regular pressure sensor calibration will be
lost when a factory reset is performed. Typically no
pressure calibration is required with a new positioner.
Possible Solutions: After replacing a main board or a
pressure sensor board, perform a Factory Pressure
Calibration. To do this, see the Pressure Sensor Board
Removal and Installation section of the IOM.

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
