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.
GGYG
●● ● ●
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.

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.

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.
