19.3 Status Code Descriptions

NOTE: Not all status codes are available with all positioner models.

GGGG
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 apply-
ing 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 shut-
off 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 po-
sitioner'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.

GGYY
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 Com-
mand 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.
....
GGRR
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.

GYGY
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.
....
GYYG
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 calibra-
tion 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.
