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+).
Action Buttons
The Apply button will save changes to the connected device.
The Retrieve button will retrieve the latest information from the device.
Warnings and Alarms
Supply Pressure High
•
Definition: The supply pressure is above the user set warning limit.
•
Implications: Supply pressure that exceeds the maximum rating on the
actuator can become a potential hazard.
•
Possible Solutions: Regulate the supply pressure at the positioner
below the maximum limit recommended for your actuator. Recalibrate
pressure sensors. Check the pressure sensor board
connections. Replace pressure sensor board if necessary.
Supply Pressure Low
•
Definition: The supply pressure is below the user set limit.
•
Implications: Low supply pressure can cause poor valve response or
positioner failure. The minimum recommended supply pressure for
proper operation is 1.3 bar (19 PSI).
•
Possible Solutions: Regulate the supply pressure at the positioner
above 1.3 bar (19 PSI). Ensure system air/gas supply is
adequate. Repair kinked or restricted supply tubing. Check for
pneumatic leaks in the actuator and actuator tubing. Recalibrate
pressure sensors. Check the pressure sensor board connections and
replace pressure sensor board if necessary.
