Training Complete
•
Definition: The positioner has finished gathering data for the specified
amount of time. This data can now be used to benchmark typical
conditions.
•
Possible Solutions: Data is available to set more meaningful
diagnostic warning and alarm limits.
Event Captured
•
Definition: A user-defined condition was met and a data file was
generated to show conditions at the time of the event.
•
Possible Solutions: Use the Event Capture page of the DTM to view
the data captured during the event.
Local Interface Enabled
•
Definition: 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.
Squawk Mode
•
Definition: 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 selected again remotely. 3) More than one hour has
passed since the command was issued.
Backup Control Mode
•
Definition: The positioner is controlling the position based on actuator
pressures instead of the feedback POT.
•
Possible Solutions: The feedback linkage is probably broken or the
feedback arm needs to be rotated because the POT is out of range.
