Warnings and Alarms
Position Deviation
•
Definition: The device is not controlling at the set point
•
Implications: The difference between the command and the actual
position has been greater than the user-set limit for longer than a user-
set time.
•
Possible Solutions: Review active alarms and warnings to find root
causes of this alarm. The deviation settings can be changed in the
Valve Health page of the DTM.
Position Alerts
•
Definition: The position has reached or is exceeding a user defined
upper position indicator. This is similar to a limit switch indicator.
