Product Bulletin DVC6000 HW2 Digital Valve Controller 62.1:DVC6000 HW2 November 2015 D103786X012 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. www.Fisher.com 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.

Condition Indicators (Performance Diagnostics) E1208 ERROR (RED CONDITION INDICATOR) E1209 WARNING (YELLOW CONDITION INDICATOR) 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 2 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.
