Training
The Training page allows you to view information about the training period. During the
training period, the positioner records system data and creates histograms of several
parameters. The histogram data and graphs are displayed in the DTM pages where the
related alarm limits are set. The training period should be run during normal operation,
when there are no issues. It should run over a time period that includes normal process
variations. By default, the training will begin automatically after 24 hours of continuous
operation and last 90 days (2160 hours). For more recorded system data, see
Trends .
During Training, the positioner data for the following:
•
Supply Pressure
•
Deviation
•
Friction
•
Pneumatic Leak
•
Position
•
Position Frequency
•
Position Amplitude
•
Command Frequency
•
Command Amplitude
Status Area
The Active Indicator area shows the status of the most relevant active indicator. The color
of the "LED light" corresponds to the Active Indicator and the first color of the blink code
sequence on the positioner. Generally green indicates no immediate issues. Yellow
indicates a developing issue. Red indicates the ability to control may be compromised. A
detailed list of the indicators is given in the
Alarm Congfiguraion - Alarm Annunicator page.
The Command Source field indicates weather the positioner is being controlled by digital or
