Factory Reset State
•
Definition: The positioner is in factory reset state.
•
Implications: Calibration is required to enable control.
•
Possible Solutions: Perform a Stroke Calibration (QUICK-CAL).
Calibration in Progress
•
Definition: A calibration is in progress.
•
Possible Solutions: The calibration can be canceled from the Sensor
Calibration page of the DTM, from the handheld, or by briefly pressing
the BACK button.
Signature or PST
•
Definition: 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.
Jog Command Mode
•
Definition: The positioner has been placed in a local override mode
where the valve can only be stroked using the UP and DOWN buttons.
•
Implications: 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.
PST Scheduled
•
Definition: 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.
DI Command Override
•
Definition: 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
