Valve Trim

The Valve Trim page allows you to record information about the connected valve assembly.

NOTE: This information is for record keeping and information purposes only and does not
affect the operation of the positioner or control valve.


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

The Command Source field indicates weather the positioner is being controlled by digital or
an analog (4-20 mA) command source.
