1 FIELDVUE DVC6200 Digital ValveControllerThe FIELDVUE DVC6200 Digital Valve Controller is aHARTr communicating instrument that converts atwo wire 4 20 mA control signal into a pneumatic outputto an actuator. It can easily be retrofitted in place ofexisting analog positioners on most Fisher and non Fisherpneumatic Linkage Less Non Contact Position Feedback Thehigh performance, linkage less feedback systemeliminates physical contact between the Valve stemand the DVC6200 . There are no wearing parts so cyclelife is Built to Survive The field proven DVC6200 has fullyencapsulated electronics that resist the effects ofvibration, temperature, and corrosive atmospheres. Aweather tight wiring terminal box isolates field wiringconnections from other areas of the Actuator Overpressure PreventionPerformancen Accurate and Responsive The two stage positionerdesign provides quick response to large step changesand precise control for small setpoint Travel Control/Pressure Fallback Valve positionfeedback is critical to the operation of a Digital valvecontroller.

2 The DVC6200 can detect position feedbackproblems and automatically revert to pressure controlmode to keep the Valve Ramped Cutoff provides smooth transition fromthrottling control to shutoffEase of Usen Enhanced Safety The DVC6200 is a HART communicating device, so information can beaccessed anywhere along the loop. This flexibility canLINKAGE LESSFEEDBACK SYSTEMW9616reduce exposure to hazardous environments andmake it easier to evaluate valves in hard to Faster Commissioning HART communications allowsyou to quickly commission loops with a variety oftools, either locally at the Valve assembly or Easy Maintenance The DVC6200 is modular indesign. Critical working components can be replacedwithout removing field wiring or pneumatic Hardware Savings When installed in an integratedcontrol system, significant hardware and installationcost savings can be achieved.

3 Valve accessories suchas limit switches and position transmitters can beeliminated due to the integrated position transmitteror switch Increased Uptime The self diagnostic capability ofthe DVC6200 provides Valve performance and healthevaluation without shutting down the process orpulling the Valve assembly from the Improved Maintenance Decisions Digitalcommunication provides easy access to the conditionof the Valve .

Condition IndicatorsERROR(RED CONDITION INDICATOR)WARNING(YELLOW CONDITION INDICATOR)E1208E1209 EVENT LOG PROVIDES POSSIBLE CAUSES ANDRECOMMENDED CORRECTIVE ACTIONSE1210 Valve DiagnosticsThe DVC6200 Digital Valve Controller provides a broadand deep portfolio of Valve diagnostic the 475 Field Communicator is used to checkfor Valve alerts and operational status, or ValveLinksoftware is used for comprehensive diagnostic test andanalysis, the tools are easy to use.

4 When installed as partof a HART communicating system, the DVC6200 deliversprompt notification of current or potential equipmentissues and supports NAMUR NE107 alert Diagnostics enable condition andperformance monitoring of the entire Valve assembly(not just the Digital Valve Controller ) while the Valve isactively controlling the process. When conductingPerformance Diagnostics tests, the Valve does NOT movebeyond the normal setpoint changes driven by theprocess Controller . The DVC6200 uses statisticalalgorithms to determine condition and performancerelated issues based on live readings from the manyon board sensors. Results are then displayed graphically,with severity indicated by a red/yellow/green indicator(figure 1).

5 A detailed description of the identified issue aswell as suggestions for recommended actions of identifiable issues are:n Low or high air supply or pressure droopn Incorrect regulator settingn Dirty air supplyn External air leak (actuator diaphragm or tubing)n Calibration shiftn Valve stuckn Piston actuator O ring failuren Excessive or insufficient Valve assembly frictionn Excessive Valve assembly deadbandn Elastomer failure in the DVC6200n Broken actuator springPerformance Diagnostics also provide access tofull stroke dynamic testing of the Valve assemblyincluding; Valve signature, dynamic error band, stepresponse, and stroke check. These tests change theinstrument setpoint at a controlled rate and areperformed while the Valve assembly is isolated from additional information on FIELDVUE diagnostics andValveLink software refer to Fisher Bulletin :ValveLinkSoftware (D102227X012).
