Fishert FIELDVUEt DVC6000 HW2 Digital
Valve Controller
The FIELDVUE DVC6000 HW2 digital valve controller is a
HARTr communicating instrument that converts a
two‐wire 4‐20 mA control signal into a pneumatic output
to an actuator. It can easily be retrofitted in place of
existing analog positioners on most Fisher and non‐Fisher
pneumatic actuators.
Features
Reliability
n Built to Survive— The field proven DVC6000 HW2
instrument has fully encapsulated electronics that
resist the effects of vibration, temperature, and
corrosive atmospheres. A weather‐tight wiring
terminal box isolates field wiring connections from
other areas of the instrument.
Performance
n Accurate and Responsive— The two‐stage positioner
design provides quick response to large step changes
and precise control for small setpoint changes.
n Travel Control/Pressure Fallback— Valve position
feedback is critical to the operation of a digital valve
controller. The DVC6000 HW2 can detect position
feedback problems and automatically revert to I/P
transducer mode to keep the valve operational.
Ease of Use
n Enhanced Safety— The DVC6000 HW2 is a HART
communicating device, so information can be
accessed anywhere along the loop. This flexibility can
reduce exposure to hazardous environments and
make it easier to evaluate valves in hard to reach
locations.
n Faster Commissioning— HART communications allows
you to quickly commission loops with a variety of
tools, either locally at the valve assembly or remotely.

W8373
n Easy Maintenance— The DVC6000 HW2 digital valve
controller is modular in design. Critical working
components can be replaced without removing field
wiring or pneumatic tubing.
Value
n Hardware Savings— When installed in an integrated
control system, significant hardware and installation
cost savings can be achieved. Valve accessories such
as limit switches and position transmitters can be
eliminated because this information is available via the
HART communication protocol.
n Increased Uptime— The self‐diagnostic capability of
the DVC6000 HW2 digital valve controller provides
valve performance and health evaluation without
shutting down the process or pulling the valve
assembly from the line.
n Improved Maintenance Decisions— Digital
communication provides easy access to the condition
of the valve. Sound process and asset management
decisions can be made by analysis of valve information
through Fisher ValveLinkt software.

Valve Diagnostics
The DVC6000 HW2 digital valve controller provides a
broad and deep portfolio of valve diagnostic capabilities.
Whether the 475 Field Communicator is used to check
for valve alerts and operational status, or ValveLink
software is used for comprehensive diagnostic test and
analysis, the tools are easy to use. When installed as part
of a HART communicating system, the DVC6000 HW2
delivers prompt notification of current or potential
equipment issues.
Alerts assist in identification and notification of the
following situations:
n Valve travel deviation due to excessive valve friction or
galling
E1210
EVENT LOG PROVIDES POSSIBLE CAUSES AND
RECOMMENDED CORRECTIVE ACTIONS
related issues based on live readings from the many
on‐board sensors. Results are then displayed graphically,
with severity indicated by a red/yellow/green indicator
(figure 1). A detailed description of the identified issue as
well as suggestions for recommended actions are
provided.
Examples of identifiable issues are:
n Low air supply or pressure droop
n Incorrect regulator setting
n Dirty air supply
n External air leak (actuator diaphragm or tubing)
n Calibration shift
n Valve stuck
n High cycle due to dither or improper tuning
n Piston actuator O‐ring failure
n Total travel movement accumulation beyond a
n Excessive valve assembly friction or deadband
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 DVC6000
HW2.
Additionally, Performance Diagnostics enable condition
and performance monitoring of the entire valve assembly
(not just the digital valve controller) while the valve is
actively controlling the process. When conducting
Performance Diagnostics tests, the valve does NOT move
beyond the normal setpoint changes driven by the
process controller. The DVC6000 HW2 uses statistical
algorithms to determine condition and performance

n Elastomer failure in the DVC6000 HW2
n Broken actuator spring
Performance Diagnostics also provide access to
full‐stroke dynamic testing of the valve assembly
including: valve signature, dynamic error band, step
response, and stroke check. These tests change the
instrument setpoint at a controlled rate and are
performed while the valve assembly is isolated from the
process.
