费希尔DVC6000系列定位器的调校
FISHER DVC6000阀门定位器检维修规程
Fisher DVC6000阀门定位器检维修规程1、工作原理DVC6000系列定位器由印刷电路板组件（PWB）、I/P转换器、气动放大器、行程传感器、端子盒等组成。
如图4-20mA输入信号经过端子盒，然后连到印刷电路板组件与模块。
经数字算法处理并转换成模拟量作为I/P驱动信号，当输入信号增大时，去I/P转换器的驱动信号增大。
使得I/P转换器的线圈和衔铁之间的磁吸引力增加，挡板靠近喷嘴，即喷嘴背压上升。
喷嘴背压送人气动放大器子模块的输入膜片，使气动放大器的膜片组件移动，使得阀芯去打开供气口和关闭排气口。
以增加送去执行机构的输出压力。
使执行机构移动，阀行程传感器通过反馈连杆感受阀杆的位置变化，阀行程传感器信号送印刷电路板与输入信号比较运算，直到阀门到达正确的阀位后，印刷电路板组件使I/P转换器的驱动信号稳定下来。
当输入信号减少时，动作方向相反。
2、接线3、调校先将HART手操器接到定位器的LOOP正负端子，打开HART手操器。
1)选择进入SETUP后，选择Detailed Setup，为了调校必须对仪表模式和保护进行正确设定。
分别选择instrument mode与prtection进行设定，将仪表模式选择为out of service确认，再将保护选择为none 确认后返回到SETUP菜单。
2)入calibrate菜单，直接选择Auto calib Travel后将进行自动调校，调校将自动结束。
3)调校自动结束后，必须分别将仪表模式与保护重新设定为inservice与prtection并确认后，调校结束。
注意：以上步骤中，必须按照HART的每一步的提示，其中有提示跳线辅助端子，方可正确完成。
4、维护。

（注：减压调节时通过定位器上的减压孔来排压）3.气动保位阀作用：当气源失气时，上图虚线支路的压力减少到丧失，从而导致气动保位阀关闭，从而锁住薄膜阀内压力使阀门保持在原位置。
（注：一般气动保位阀失气需要一段时间从而导致阀门位移发生一段小位移，在实际观察中发现的，不知道对不对？）4.反馈连杆随阀门上下运动从而改变反馈电流在4－20MA线性变化来表征阀杆位移5.气开阀门和气关阀门的原理相同•阀门调整1.调整前检查性校准通过控制室操作装置(操作器或CRT)，先发出量程的0%，25%，50%，75%，100%输出信号，然后发出100%，75%，50%，25%，0%输出信号，依次记录每一校准点位置反馈值、执行机构和操作装置的实际位置定位器表面涂层应光洁、完好，无剥落、碰伤及划痕等缺陷；紧固件不应有松动和损伤等现象；铭牌及标志内容应正确；２手动进汽使阀门的开度大致为50%左右，使定位器的连接臂为水平位置；３调整定位器供气压力在规定范围内，在规定的输入信号气源压力时，调节定位器的零点和量程螺丝，使调节机构在全程范围内的基本误差不大于允许误差；３当气源压力偏离额定值±10kPa时，定位器的行程变化应不大于允许误差限的绝对值。

FISHER_DVC6000定位器调试说明
D 102758X 012FIELDVUE R DVC6000 Series Digital ValveControllersFIELDVUE RDVC6000 Series digital valvecontrollers (figures 1 and 2) are communicating,microprocessor-based current-to-pneumaticinstruments. In addition to the traditional function of converting a current signal to a valve-position pressure signal, DVC6000 Series digital valvecontrollers, using HART R communications protocol,give easy access to information critical to process operation. This can be done using a Model 375 Field Communicator at the valve or at a field junction box,or by using a personal computer or a system console within the control room. Using HART communication protocol, information can be integrated into a control system or received on a single loop basis.W7957-1 / ILFigure 1. Type DVC6010 Digital Valve Controller Mounted ona Sliding-Stem Valve Actuator DVC6000 Series digital valve controllers can be used on single- or double-acting actuators. Thedigital valve controller receives feedback of the valve travel position plus supply and actuator pneumatic pressure. This allows the instrument to diagnose not only itself, but also the valve and actuator to which it is mounted. This provides you with very costeffective maintenance information, so that required maintenance can be performed on the instrument and valve when there really is a need.Wiring is economical because DVC6000 Seriesdigital valve controllers use two-wire 4 to 20 mA loop power. This provides for low cost replacement of existing analog instrumentation. The DVC6000Series digital valve controller’s two-wire designavoids the high cost of running separate power and signal wiring.W7960-1 / ILFigure 2. Type DVC6010 Digital Valve Controller Mounted onType 585C Piston Actuator(continued) 2actuator has been tested to 15 meters (50 feet) maximum without performance degradation.2. These terms are defined in ISA Standard S51.1.3. Normal m3/hr--Normal cubic meters per hour at 0_C and 1.01325 bar, absolute; Scfh--Standard cubic feet per hour at 60_F and 14.7 psia.4. Values at 1.4 bar (20 psig) based on a single-acting direct relay; values at5.5 bar (80 psig) based on double-acting relay.5. Not applicable for Type DVC6020 digital valve controllers in long-stroke applications or remote-mounted Type DVC6005 digital valve controllers with long pneumatic tubing lengths.6. Approvals for remote-mounted units are pending.7. The Low Bleed Relay is offered as standard relay for DVC6000 ESD tier, used for On/Off applications.FeaturesD Improved Control—Two-way digital communications give you current valve conditions. You can rely on this real-time information to make sound process management decisions. By analyzing valve dynamics through AMS ValveLink Software , you can identify control areas needing improvement and maintain a high level of system performance. D Environmental Protection—You can avoid additional field wiring by connecting a leak detector or limit switch to the auxiliary terminals in theDVC6000 Series digital valve controller. In this way, the instrument will issue an alert if limits are exceeded.34D Enhanced Safety—You can check instrumentand valve operation and keep the process running smoothly and safely from a remote location. Access is possible at a field junction box, marshalling panel, or within the safety of the control room using either a 375 Field Communicator, a notebook PC, or a system workstation. Your exposure to hazardous environments is minimized and you can avoid having to access hard-to-reach valve locations.D Hardware Savings—DVC6000 Series digital valve controllers, when used in an integrated system, allow you to realize significant hardware and installation cost savings by replacing other devices in the process loop, such as positioners and limit switches, with a FIELDVUE digital valve controller.D Built to Survive—Field-tough DVC6000 Series digital valve controllers have fully encapsulated printed wiring boards that resist the effects of vibration, temperature, and corrosive atmospheres.A separate weather-tight field wiring terminal box isolates field-wiring connections from other areas of the instrument.D Increased Uptime—With the self-diagnostic capability of DVC6000 Series digital valve controllers, you can answer questions about a valve’s performance, without pulling the valve from the line. You can run diagnostics (I/P and relay integrity, travel deviation, and on-line friction and deadband analysis and trending) while the valve is in service and operating. You can also compare the present valve/actuator signature (bench set, seat load, friction, etc.) against previously stored signatures to discover performance changes, before they cause process control problems.D Faster Commissioning—The two-way communication capability allows you to quickly commission loops by remotely identifying each instrument, verifying its calibration, reviewing stored maintenance notes, and more.D Easy Maintenance—DVC6000 Series digital valve controllers are modular in design. The single master module can be removed from the instrument housing without disconnecting the field wiring, pneumatic connections or stem linkages. This module contains the critical sub-modules so component removal is quick and simple.DiagnosticsDVC6000 Series digital valve controllers are packed with user-configurable alerts and alarms. When integrated with a HART communication-based system, these flags provide real-time notification of current and potential valve and instrument problems. With AMS ValveLink R Software, tests can be performed to identify problems with the entire control valve assembly. Diagnostic capabilities available are Performance Diagnostics (PD) and Advanced Diagnostics (AD).Performance DiagnosticsPerformance Diagnostics enables the use of diagnostics while the valve is in service and operating.D Red/Yellow/Green Condition Indicator(see figure 3)D I/P and Relay Integrity DiagnosticD Travel Deviation DiagnosticD1-Button DiagnosticD On-Line Friction and Deadband Analysis(see figure 4)D Friction and Deadband TrendingWhile all diagnostics can be run while the valve is inline, only the Performance Diagnostics can be performed while the valve is in service and operating.5ERROR(RED)NO CONDITIONS HAVE BEEN DETECTED(GREEN)Figure 3. Red/Yellow/Green Condition Indicators, Shown in AMS ValveLink SoftwareFigure 4. Valve Friction and Deadband AnalysisAdvanced DiagnosticsAdvanced Diagnostics include the following dynamic scan tests:D Valve Signature (see figure 6)D Dynamic Error Band D Instrument Drive SignalThese diagnostic scans vary the positioner set point at a controlled rate and plot valve operation to determine valve dynamic performance. The valve signature test allows you to determine thevalve/actuator friction, bench set, spring rate, and seat load. The Dynamic Error Band test is a combination of hysteresis and deadband plus “slewing.” Hysteresis and deadband are static measurements. However, because the valve is moving, a dynamic error, or “slewing” error is introduced.Dynamic scan tests give a better indication of how the valve will operate under process conditions which are dynamic, not static.The Step Response Test checks the valveassemblies response to a changing input signal. and plots travel versus time. The end results of this test allow you to evaluate the dynamic performance of the valve. The Performance Step Test (25pre-configured points) provides a standardized step test with which to evaluate your valve performance.It utilizes small, medium and large changes.Advanced Diagnostics are performed with AMS ValveLink Software . The valve must be out ofservice for Advanced Diagnostics to be performed.6W8082 / ILHART MULTIPLEXERControl System I/O4-20 mA+HARTFigure 5. Integrate Information from the Digital Valve Controller into a Non-HART Compatible Control System With AMS ValveLinkSoftware’s Modbus InterfaceW7468/ILFigure 6. The Valve Signature DisplayIntegrationD Non-HART Systems—Because DVC6000Series digital valve controllers operate with atraditional 4 to 20 mA control signal, they directlyreplace older analog instruments.Microprocessor-based electronics provide improvedperformance along with repeatable and reliableconfiguration and calibration.D Modbus with AMS ValveLink Software andHART Multiplexers—HART communication allowsyou to extract more value from DVC6000 Seriesdigital valve controllers beyond their inherentimproved performance. When integrated into amultiplexer network and using AMS ValveLinkSoftware, the device and valve information isreal-time. From the safety of a control room, multipleinstruments can be monitored for alerts and alarms.Additionally, tasks such as configuration, calibrationand diagnostic testing do not require special trips tothe field. AMS ValveLink Software can communicatevia Modbus to the distributed control system (DCS)to provide critical information such as valve travelalerts and alarms (figure 5).D Integrated Control System—A control systemwith HART communication capabilities has the abilityto directly gather information from DVC6000 Seriesdigital valve controllers. Information such as valvetravel, alerts and alarms can be seamlesslyaccessed to provide a view into the field device fromthe safety of the control room.71200 Hz “1”2200 Hz “0”AVERAGE CURRENT CHANGE DURING COMMUNICATION = 0A6174/ILFigure 7. HART rFrequency Shift Keying TechniqueFigure 8. Perform Configuration and Calibration at the Valve or Anywhere on the 4 to 20 mA Loop with the Model 375Field CommunicatorCommunicationHART Protocol OverviewThe HART (Highway Addressable Remote Transducer) protocol gives field devices thecapability of communicating instrument and process data digitally. This digital communication occurs over the same two-wire loop that provides the 4 to 20 mA process control signal, without disrupting the process signal (figure 7). In this way, the analog process signal, with its faster response, can be used for control. At the same time, the HART digital communication gives access to calibration,configuration, diagnostic, maintenance, andadditional process data. The protocol provides total system integration via a host device.Model 375 Field CommunicatorYou can perform configuration and calibration at the valve or anywhere on the two-wire loop via a Model 375 Field Communicator (figure 8). Powerful tools such as the Setup Wizard and Auto TravelCalibration automate the tasks of commissioning DVC6000 Series digital valve controllers. Theseautomation tools not only save time, but also provide accurate and repeatable results.AMS ValveLink SoftwareAMS ValveLink Software is a Windows-based software package that allows easy access to the information available from DVC6000 Series digital valve controllers.Using AMS ValveLink Software, you can monitor the performance characteristics of the valve and obtain vital information without having to pull the valve from the line. I/P and Relay Integrity and Travel Deviation Diagnostics, as well as On-Line Friction andDeadband Analysis and Trending can be run while the valve is in service and operating. ValveSignature, Dynamic Error Band, and Step Response are displayed in an intuitive user-friendlyenvironment that allows easy interpretation of data.Diagnostic graphs can be superimposed over those previously stored to view areas of valve degradation.This allows plant personnel to concentrate efforts on equipment that needs repair, avoiding unnecessary maintenance. This diagnostic capability is readily accessible and available to you either in the control room or on the plant floor. In addition to the diagnostic features, AMS ValveLink Softwarecontains an Audit Trail, Batch Runner for automating repetitive tasks, and Trending to view valve performance.AMS ValveLink Software provides integration into AMS and DeltaV, with HART and Fieldbus communications.TRAVEL SENSORTERMINAL BOXTERMINAL BOX COVERPRINTED WIRING BOARD ASSEMBLYI/P CONVERTERPNEUMATIC RELAYGAUGESCOVERW8083-1 / ILFigure 9. DVC6000 Series Digital Valve Controller Assembly (valve-mounted instrument)Principle of OperationDVC6000 Series instruments (figures 9 and 10) receive a set point and position the valve where it needs to be.D The input signal provides electrical power and the set point simultaneously. It is routed into the terminal box through a twisted pair of wires.D The input signal is then directed to the printed wiring board assembly where the microprocessor runs a digital control algorithm resulting in a drive signal to the I/P converter.D The I/P converter assembly is connected to supply pressure and converts the drive signal into a pressure output signal.D The I/P output is sent to the pneumatic relay assembly. The relay is also connected to supply pressure and amplifies the small pneumatic signal from the I/P converter into a single larger pneumatic output signal used by a single-acting actuator. For double-acting actuators, the relay accepts the pneumatic signal from the I/P converter and provides two pneumatic output signals.D The change in relay output pressure to the actuator causes the valve to move.D Valve position is sensed through the feedback linkage by the instrument’s travel sensor. The travel sensor is electrically connected to the printed wiring board to provide a travel feedback signal used in the control algorithm.The valve continues to move until the correct position is attained.8E0408 / ILFigure 10. DVC6000 Series Digital Valve Controller Block DiagramInstallationThe Type DVC6010 digital valve controller is designed for yoke mounting to sliding stem actuators. Type DVC6020 digital valve controllers are designed for mounting to rotary actuators or long stroke sliding stem actuators (over 4-inches travel). Type DVC6030 digital valve controllers are designed for mounting on virtually any quarter-turn actuator. Dimensions for valve-mounted instruments are shown in figures 11, 12, and 13. Dimensions for remote-mounted instruments are shown in figures 14 and 15.The Type DVC6005 digital valve controller base unit may be remote mounted on 2-inch pipestand or wall.

FISHERDVC6000系列阀门定位器原理和检修
FISHERDVC6000系列阀门定位器原理和检修在DETAIL SETUP中，MODE中，有个INSTRUMENT MODE，这个里面有2个选项，IN SERVICE 和OUT OF SERVICE。
IN SERVICE：外部信号能控制阀门动作，此模式下，定位器的很多参数不能设定。
OUT OF SERVICE：外部信号无用，此时能设置各种定位器参数，如RESPONSE TIME，TAG等等。
很多时候，阀门不动作，可能就是定位器的模式跳到了OUT OF SERVICE。
一个新的定位器，首先要做的是TRAVEL SENSOR的调整，A柱加上的时候，为0％位置，调整内六角，调整到600左右。
然后是满点。
其后，连接阀杆和反馈臂，注意阀门行程是多少，连接点就要设在多少。
然后可以用BASIC SETUP中，有个AUTO WIZARD来自动设置校验定位器。
在BASIC SETUP中，有个AUTO WIZARD，能自动校验阀门，这个WIZARD分3步：①设置ACTUTOR型号，有各个厂家的可以用。
（GCT的是FISHER的667执行机构）②设置RELAY的作用方式，A作用（螺丝刀拨到－）（GCT的是A作用），B作用（螺丝刀拨到＋），双作用。
③设置自动调整的中间点的位置，可以外加电流信号，调整到50％开度的准确开度，或者用厂家的DEFAULT设定值。
建议用外加电流信号。
在CALIBRATION中，有各种元件的CALIBRATION校验，有TRAVEL SENSOR的，压力传感器的，输入电流模版的。
可以对单独的元件进行校验。

DVC6000 调试基本步骤
DVC6010 调试基本步骤：准备工作：定位器调试前必须已将机务阀杆与执行器输出推杆正确连接，并已将定位器反馈臂与执行器推杆上反馈用连接臂正确连接。
同时气源压力必须调整到正确值。
开度反馈如用T ri－Loop，必须先激活并已正确设置！机务阀杆与执行器输出推杆连接：因执行器为单作用下缸进气的气开式阀门（开时定位器反馈臂逆时针旋转向上），连接前要求机务将阀门门杆完全向下压倒底，保证阀门处于完全关闭状态。
直接向执行器气缸输入铭牌“BENCH SET：14 —30”中下限压力并适当放大1~2psi，然后将执行器输出推杆与机务阀杆连接。
连接后的理想状态是当气缸输入压力大于“BENCH SET：14 —30”中下限压力时能较快地开始开启，当气缸输入压力达“BENCH SET：14 —30”上限时能够全开。
定位器反馈臂连接：断开至执行器气缸气源，阀门处于全关状态，确认执行器输出推杆上反馈用连接臂已正确用螺丝固定，从定位器内部旋出连接用定位销，将定位销穿过定位器反馈臂上标记为“A”的孔（如是气关式则为“B”孔）并插入定位器壳体上的定位孔，使定位器反馈臂固定不动，根据铭牌“TRA VEL：3/4（inch）”中的执行器行程值，上下滑动调整调整臂与推杆上连接臂的位置，使调整臂在定位器反馈臂滑槽内对准有相应行程标注的数字刻度处，然后拧紧调整臂与推杆上连接臂的连接固定螺母。
注意，调整臂是将定位器反馈臂与执行器推杆上反馈连接臂的连接过渡。
气源压力调整：调整减压阀使气源压力闭执行机构要求的最大值（参考BENCH SET 上限）高0.3bar（5psi），注意此压力必须能使锁气器完全顶开，离开锁气状态。
按检修规程要求锁气器闭锁压力的调整一般不得低于0.3MPa。
Tri－Loop激活并设置：先通讯器连接DVC6000，ONLINE Setup&Diag Detailed Setup Mode Burst Burst Enable，设置成激活状态。

①从On line(在线)菜单里选择Setup&Diag(设置和诊断)——Basic setup(基本设置)——Manual setup(手动设置)——Instrument Manual(仪表模式)——Out of service(非工作状态)。
②Basic setup (基本设置)——Auto setup (自动设置)——Auto Calib Travel（自动校验行程）剩余的自动校验步骤是自动进行的。
自动校验完成后，HART会提示您将仪表设置到In Service(投用状态)。
③如果在完成基本设置和校验之后，阀门还是振荡或过调（不稳定），或响应不灵（响应缓慢），您可以Auto Setup （自动设置）菜单中Performance Tune （性能优化整定）或Stabilize/Optimize（稳定/优化）改善调试结果；其中有两种选择：Standard(标准)、Advanced(高级)。
在Standard(标准)中如果阀门工作不稳定，用Decrease Response(削弱响应)来使阀门工作稳定；如果阀门响应缓慢，用Increase Response(增加响应)来使阀门响应灵敏。
如果用Decrease Response或Increase Response后阀门超调还是很严重，需要选择Advanced(高级)项，除了Decrease Response(削弱响应) 和Increase Response(增加响应)，还有Decrease Damping(降低阻尼) 选择允许阀门有更多过调的阻尼值和Increase Damping(增加阻尼) 选择减少阀门过调的阻尼值。
④对于FISHER DVC6000系列数字阀门定位器，典型的安装调试方式为：从On line(在线)菜单里选择Setup&Diag(设置和诊断)——Basic setup(基本设置) ——Auto setup (自动设置) ——Setup Wizard(设置诀窍)，首先是选择所调试的执行机构制造商或执行机构型号，如果在Setup Wizard(设置诀窍)中没有列出，就选择Other（其它）来作为执行机构制造商或执行机构型号，被提示设定的参数如下：Actuator Type（执行机构类型）选项如下：Spring&Diaphragm（弹簧膜片式）、Piston Double－acting without spring（无弹簧双作用气缸式）、Piston
Single－acting with spring（带弹簧单作用气缸式）、Piston Double－acting with spring（带弹簧双作用气缸式）。
Valve Type（阀门类型）选项如下：Rotary（旋转式）、Sliding－Stem（直通式）On Loss Of Instrument Signal，Valve（Opens or Closes）仪表失去信号时，阀门（开或关）
Feedback Connection（反馈连接）选项如下：Rotary－All（旋转式－全部）、SSTem－Standard（直通式－标准型）、SSTem－Roller（直通式－滚轮型）。
Travel Sensor Motion（行程传感器旋转方向）如果选择Yes由定位器自行确定，选No则当信号增加时行程传感器旋转方向为顺时针则输入Clockwise、逆时针则输入Counterclockwise。
确认执行机构制造商或执行机构型号后为基本设置，如果选Yes则为使用工厂缺省值，如选No则保持表里原来的值。
工厂缺省值如下：
在输入执行机构信息后，会提示调整气动放大器，完成后就是调校阀门行程，按照提示进行自动校验。
