Training Status
Training Status is present on this page because one or more fields or graphs shows data
that was gathered during the training process. The field shows one of the following states:
•
Training Enabled - which indicates system data is being recorded. Training should
run during normal system behavior.
•
Training Disabled - which indicates NO system data is being recorded.
•
Training Complete which indicates that the time period for training has expired and
the data is stored in the positioner.
NOTE: The Training function requires the Pro positioner upgrade level (522MD+).

Warning and Alarms
Valve Cycles
•
Definition: The valve cycle limit has been exceeded.
•
Implications: Each cycle represents two reversals of the direction of
valve movement. The cycle counting criterion and count limit are set by
the user to track the usage of the valve.
•
Possible Solutions: Follow routine procedures for maintenance when
the limit is reached such as checking the packing tightness, and
checking linkages for wear, misalignment, and tightness. After
maintenance, reset the cycle accumulator.
Valve Travel
•
Definition: The total accumulated valve travel limit has been
exceeded.
•
Implications: The travel is accumulated in both directions. The travel
counting criterion and limit are set by the user to track the usage of the
valve.
