Valve Diagnostics
The DVC6200 digital valve controller provides a
comprehensive library of valve diagnostic alerts, as
shown in figure 1. These alerts are easily accessed with
the 475 Field Communicator. When installed as part of a
HART communicating system, the DVC6200 delivers
prompt notification of current or potential equipment
issues directly to the asset management system.
Alerts assist in identification and notification of the
following situations:
n Valve travel deviation due to excessive valve friction
or galling
n High cycle due to dither or improper tuning
n Total travel movement accumulation beyond a
specified point resulting in packing wear
n Valve travel above or below a specified point
n Various instrument mechanical and electrical issues
These alerts are stored in memory on board the
DVC6200.
