M aso n eilan*S V I*II A P 定位器作业指导书编制：周利鹏审核：王振辉储运公用成品油班组SVI II AP定位器作业指导书1、工作原理SVI II AP是智能电气定位器，它从控制器接收4-20mA电气位置设定点信号并与阀门位反馈传感器比较位置设定点输入信号。
位置设定点和位置反馈之间的差异通过位置控制算法分析计算输出为I/P转换器设定伺服信号。
I/P的输出压力由驱动执行机构的气动气路放大器放大。
一旦设定点和阀门位反馈之间的误差在范围之内，对伺服信号不进行其它纠正，以保持阀位。
阀门定位器外观如图1-1所示。

当用于减小显示值时，长按按钮就会使值以更快速度减小。
右键按钮：标记为+，允许您通过菜单结构进入下一个菜单项目，或者增加数字显示屏上当前显示的值。
当用于增加显示值时，长按按钮就会使值以更快速度增加。
4、NORMAL 运行模式和 MANUAL 模式菜单当离开NORMAL模式进入MANUAL模式时，阀门处于它离开NORMAL时所处的最后位置。
在MANUAL模式下，设备不会对4-20 mA的信号作出响应。
但是，SVI II AP设备仍然可以对HART命令作出响应，包括定位阀门的HART命令。
当你从NORMAL运行模式菜单切换到VIEW DATA或VIEW ERR菜单，阀门仍然处于NORMAL 模式，并且仍然对4-20mA信号作出响应。

(中广核核电运营有限公司广东深圳 518034)摘要：本文以梅索尼兰SVI智能定位器在核电厂汽机旁路系统应用为例，介绍了SVI智能阀门定位器的结构、性能特点、调试方法及常见的故障现象和解决方法，为以后检修工作提供参考。
关键词：SVI智能定位器；故障现象；解决方法概述阀门定位器是气动调节阀的关键附件之一，他直接影响调节阀的可用性。
随着工业智能化的发展，微电子技术在阀门定位器的应用，使智能阀门定位器性能和功能有了大的进步。
智能阀门定位器与机械式比较有着显著的优点：校验方便、精度高等。
但是在复杂的环境下，智能定位器也出现过一些问题，本文以核电厂汽机旁路系统应用为例，介绍SVI定位器在系统的应用及其原理、校验方法和常见故障现象。
1 智能定位器在系统中的应用在核电厂中，当反应堆功率与汽机负荷不一致时，汽机旁路排放系统通过把多余的蒸汽排向冷凝器、除氧器和大气为反应堆提供一个“人为”的负荷，从而避免核蒸汽供应系统中温度和压力超过保护阈值，确保电站的安全。
汽机旁路排放系统的排放阀使用气动调节阀，由于该系统在投运时现场温度较高、管道振动大，为了提高可靠性，在的核电厂内使用了分体式SVI智能阀门定位器控制旁路蒸汽排放。
2 智能定位器工作原理SVI系列智能阀门定位器采用非接触阀位传感器和在微处理器板进行定位控制，并具有诊断功能，通过HART通信实时性能监视和获取数据分析有效开展了调节阀预测性维护。
如图1： SVI智能定位器的原理图，该智能定位器为二线制电流回路供电，输入控制信号4-20mADC+HART，当阀门定位器正确安装到控制阀，输入控制信号和气源接通后，电子模块的微处理器开始读取输入控制信号和阀位传感器信号，并进行比较运算，对两者的偏差按PID算法处理，输出I给喷嘴挡板结构的I/P电气转换器的电磁线圈，引起喷嘴挡板间隙改变，进而变为相对应的前置气信号PI，在经气动放大器放大，使气动输出变化，加到执行机构上驱动阀杆位移到设定位置。

下面举出几个具体列子:1. 阀门反馈不正常解决方法:启动HART→进入MANUAL 模式→Calibration Menu→Range→Autostops 运行结束后,退出Calibration Menu 模式,进入Normal 模式即可2. 阀门波动大解决方法：启动HART→进入MANUAL 模式→Calibration Menu→Tuning→PID coefficient 选2 次OK→选择一次entet→将I 值相应放大→选择enter7 次后再选择一次OK,修改I 参数完成.运行结束后,退出Calibration Menu 模式,进入Normal 模式即可3. 零位或满位偏差大解决方法:启动HART→进入MANUAL 模式→Calibration Menu→Range→Autostops 运行结束后,退出Calibration Menu 模式,进入Normal 模式即可4.阀门不动作从以下几个方面检查: 1) 检查阀门是否送电,是否有气源和指令线是否有问题2) 有手动装置的阀门检查是否阀门在手动位置3)是否用HART375 调试时打到MANUAL 模式,调试结束后未返回Normal 模式FISHER 调节阀调试方法:在调试之前首先确认阀门的Travel值(阀体上的标牌上有标注,比如1/4,3/4 等) ,且使阀门处于初始状态(即全开或全关,根据阀门是气开阀还是气关阀而定) ,然后将定位器外壳螺丝松开, 打开外壳取出里面的黑色小圆棒将小圆棒穿过定位器与阀杆连接部分后卡在定位器边上的小孔上,将连接部分可移动的杆放在与阀门Travel 值对应的位置上固定即可，将信号源和HART连接到定位器后,启动HART,选择0(当位置反馈装置是Tri-Loop 时) 或定位器的型号(4210 型位置反馈装置)→Setup&Diag→Detailed Setup→Mode→Instrument Mode→Out of service(注意:此项再调试完毕后要返回到In service)→返回Basic Setup→ Auto Setup→Auto Calib Travel→Manual(注意:此处有一个选择交叉点的过程,当在交叉点的时候,要求阀杆与定位器连接部分标有Travel 值的空档处处在水平位置)→Analog→In serviceFISHER 调节阀位置反馈装置调试方法：1. 就地安装的4210型位置反馈装置，首先用信号源加12mA 的信号, 使阀门开度在50%, 用万用表量电路板上的TP3 和TP4 的电压,要求当位置反馈装置与阀杆连接处的横档在水平位置时,二者之间的电压是1.25V,若不是则进行调整.然后用信号源加4mA信号,量TP1 和TP2之间的电流,看反馈是4mA 还是20mA,如果是一个接近4mA的数就调整调零旋钮，使反馈的信号为4mA;如果是一个接近20mA的数就调整量程旋钮使反馈的信号为20mA.同样的方法来确定当给出的信号是20mA 时反馈的信号,如此多次直至确定零位和量程2. 电子间机柜内安装的Tri-Loop 位置反馈装置将HART连接到Tri-Loop位置反馈装置的通讯连接端口上,启动HART,进入Utility→ Configure HART Application→Polling→Digital Poll,然后退出到主画面选择Online→选择定位器的型号→Setup&Diag→Detail Setup→Mode→Burst→BurstEnable→Enable→返回Burst 画面选择Burst Command→HART Univ Cmd 3→返回到主画面后选择Online→"1"(指Trip-Loop)→Device Setup→BasicSetup→Configure Channels→Configure CH1→将Burst Variable 的类型改为"QV"Units 设为,"%"LRV 设为,"0",URV 设为"100",CH1 Enabled 设为"YES"然后保存即可.瑞基调门调试方法:瑞基调门调试是使用遥控器来调试的, 使用遥控器对中液晶显示屏按"┙"输入口令"000"进入一级设定菜单, 在一级设定菜单里主要是确定阀门的开关限位, 此时可手动将阀门打到全开(或全关)位置,然后使用遥控器按"↓"选择"打开限位"(或关闭限位) ,按"┙"进入,然后确定保存即可.之后退回主菜单,进入二级设定菜单,在二级菜单下主要是设定输入信号的量程,选择进入模拟信号量程项,选择20mA;然后将阀门打到就地控制状态用信号源加一个4mA 的信号,设定为低限阀位,加20mA 信号设为高限阀位保存即可! 此外可以使用遥控器来调整阀门的力矩,开关方向,保护方式等,具体情况根据显示屏显示选项操作即可西门子定位器调试方法:1.用定位器显示窗口下方的'+'和'-'两个按键, 使执行机构运动, 看整个机构能否自由走满行程.2.让执行器运动到行程的中间位置(直行程的反馈杆处于水平位置) ,就可以进行初始化了. 注:当你按住其中一个键的同时再按另一个键可以加快执行机构的动作.3.按功能键(小手形)5 秒后就可以进行参数设置.4.SIEMENS 定位器共有36 组参数, 可以根据现场的实际情况进行设置. 用'+'和'-' 键可以在一组参数中进行选择, 选择完后可以按一下功能键进入第二组参数的设置, 若上一个参数设置有误,可以按功能键同时按'-'键,回到上一个参数再进行设置.5.在这些参数中有几个是经常用到的. 1YFCT (执行器类型) :直行程选WAY,角行程选TURN. 2YAGL (额定反馈角度) :一般情况下,直行程设置成33,角行程90. 7SDIR: 给定方向上升RISE,给定方向下降FALL 38YDIR (操作变量方向显示) :上升RISE,下降FALL 同时改变SDIR 和YDIR 这两组参数可改变执行器动作方向. 55PRST 预设置(工厂设置) :当重新调试时,先进入55 项,长按+键 5 秒,直到显示ocay,说明已经恢复到工厂设置5.开始初始化时执行器必须处于行程的中间位置.6.参数设置完毕后用功能键切换到第四个参数,显示为'4.INIT',按住'+'键约5 秒定位器就自动进行初始化了.7.初始化一共分为5 步. 1)决定动作方向. 2)检查执行机构行程和零点. 3)确定执行机构上下动作时间. 4)确定最小的定位增量. 5)最佳的瞬时响应.8.当初始化完成时屏幕上显示"FINISH"按一下功能键显示"4.INIT".9.按功能键5 秒后,当屏幕显示有变化时松手,此时定位器处于手动模式,再按一下功能键定位器处于自动模式.10.初始化结束后定位器即进入正常工作状态.。
梅索尼兰SVI1000定位器简明使用方法
梅索尼兰SVI1000定位器简明使用方法
打开定位器外壳，可看到定位器面板，定位器上共有4个按键
从上往下，第1个按键为定位器全开全关位整定按键；
第2个按键为定位器行程调节按键（一般不用）；
第3个按键为定位器自动整定按键；
第4个按键为取消按键。
调试方法：
按下第1个按键，当它旁边的绿灯闪烁后，在2-7秒内松开按键（超时或时间不够将自动取消操作），定位器自动找阀门全开位和全关位，完成后4个指示灯会依次闪烁，再按下第3个按键，当它旁边的绿灯闪烁后，在2-7秒内松开按键（超时或时间不够将自动取消操作），定位器自动整定，完成后4个指示灯会依次闪烁，阀门定位器调试完成。
反馈应在阀门完成整定后，重新设定，用5点（4mA\8mA\12mA\16mA\20mA)进行设定。
梅索尼兰阀门说明书
阀门调试梅索尼兰是一种智能式的定位器，对该种气动阀的调试，首先对控制回路查线和接线方式确认，再次对仪表管道进行吹扫。
注意事项：在进行设置时必须从信号源输入4~20mA电流信号或者从HART（数字通信协议）输入，操作电源来自于4~20mA电流信号或者是12/24VDC电压等多支路供应。
当SVI阀门调节器或控制器没有按钮或者没有显示，如果要进行系统设置或校验，则必须用HART通信协议或者个人计算机上阀门软件来进行阀门参数设定。
该定位器又分为气开式（正作用式：4mA指令对应全关、20mA指令对应全开）、气关式（反作用式：4mA指令对应全开、20mA指令对应全关）和双气缸（厂家说：出厂是什么参数就是什么不需要更改什么参数）三种型号，梅索尼兰有一个简便操作接口、高精度的阀位执行机构、据有自动设置和调整功能。
所以我们首先要认识阀门的用户接口(interface)，梅索尼兰有三个操作按钮，○1左边一个按钮上标有“*”字样，这个按钮允许我们进行选择或者确认被改的参数；○2中间这个按钮上标有“-”字样，这个按键允许我们从下一个菜单移到上一个菜单，或者对所修改的参数进行减操作；○3右边这个按钮上标有“+”字样，这个按键允许我们从上一个菜单移到下一个菜单，或者对所修改的参数进行加操作。
当我们首次调试时，第一个看到的画面是“POS…”，如果要调整该定位器，首先必须从“POS…”切换到手动位置，画面显示的是：“MAN POS”。
当阀门在自动位置时我们可以用以下方法进行切换。
首先按标记为“+”的键，只到阀门显示（→MAN）字样时，按“*”键就可以进入手动状态，在手动状态时阀门应显示（MAN POS）字样。
这时如果再按下“*”键，就可以进行手动操作该阀门。
如果想切换到自动位置时，只要该定位器显示（MAN POS）字样时，表示阀门现为手动状态。
这时我们只有按下“+”键，只到显示（→OPER）字样，这时按“*”键，阀门将会自动进入自动状态。

Tag shutoff or bypass valves toguard against a “turn-on” while work is in progress.Bleed air from actuator and check that valve is in itsunenergized position.It is now safe to disconnect and remove any valve mounted equipmentthat is being replaced.For the procedure to mount rotary and reciprocating valves, refer to theMounting Instructions contained in the valve’s Mounting Box kit.Installing the SVI II AP Remote Position Sensor An option that is available for the SVI II AP is the Remote Position Sensor. The Remote Position Sensor, is a remotely mounted position-sensing device, that is connected electrically to an SVI II AP valve positioner. It is used as position feedback in applications where direct mounting of an SVI II AP to a valve actuator is not practical due, typically but not limited to, extreme vibration, heat or radiation.The Remote Position Sensor is a potentiometer located in an enclosure which can be mounted on a valve or damper to indicate stem position when connected to a suitable receiver. There is a three wire connection provided on a screw terminal block to interconnect to the receiving device.The SVI II AP Remote Position Sensor is suitable for installation outdoors in an industrial environment. Mounting kits are provided topermit mounting on a variety of valves.Do not remove the instrument cover or connect to an electrical circuit ina Hazardous Area unless the power is disconnected.Comply with current national and local regulationsfor electrical installation work.Installation and Set Up Installing the SVI II AP Remote Position SensorComply with national and local explosiveatmosphere regulations.Before carrying out any work on the device, poweroff the instrument or make sure that the localeconditions for potentially explosive atmospherepermit the safe opening of the cover.Installation ProcedureFor the Remote Position Sensor installation procedure refer to themounting instructions provided with the Remote Position Sensor.1.Remove the cover from the Remote Position Sensorassembly by turning the cover in a counter-clockwise (fac-ing the cover) direction.2.Connect the Remote Position Sensor to the mountingbracket by inserting four M6 x 20 mm Socket Head CapScrews through the appropriate screws holes (accordingto the valve) on the Remote Position Sensor bracket andusing a 3⁄16 inch Hex Key with tee handle.3.Route the instrument cable from the SVI II AP to theRemote Position Sensor (see Figure 3 on page 6 forinstallation instructions).4.Thread the cable through the conduit at the bottom of theRemote Position Sensor.ing a blade screwdriver, loosen the screws on theterminal block and connect the black, brown and red wiresto the appropriate labelled connectors.6.Tighten the screws.7.Attach the feedback lever to the Remote Position Sensorshaft.

This section describes the process for connecting the tubing and air supply to a single and double actingpositioner.Isolate the valve from the process and disconnect air tubing from the positioner. Disconnect air fully to avoid injury or process damage.1.Install the pneumatic tubing using a regulated, clean,instrument air supply to the air supply port (S←)2.For a single acting actuator - pipe the outbound air fromthe output pressure port (←I) to the valve actuator.3.For a double acting actuator - pipe the air going out ofeach side of valve actuator. Use both output pressure portone (←I) for one side of the actuator and output pressureport two (←II) for the other side of the actuator.4.Connect air supply and actuator outports (1⁄4 inch NPT)Supply pressure for single acting SVI II AP:20 -100 psi (1.4 - 6.9 bar) (138 - 690 kPa)Supply pressure for double acting SVI II AP:20 - 150 psi (1.4 - 10.4 bar) (138 - 1035 kPa)Minimum tubing diameter 1⁄4 inch (6mmx4mm) Note:The SVI II AP Digital Positioner is designed to operate with clean, dry, oil-free, instrument grade air to ANSI-ISA-57.3 1975(R1981) or ISA-S7.3-1975 (R1981) or with a sweet natural gassupply (SVI II AP models SVI II AP-2 through SVI II AP-3).Table 3Dew Point At least 18° F (10° C) below minimum anticipated ambienttemperatureParticulate Matter Filtered to 5 micronsOil Content Less than 1 ppm w/wContaminants Free of all corrosive contaminantsAir Supply RequirementsMasoneilan Dresser SVI II AP Quick Start Guide Single Acting PositionerThe supply and output connections for the SVI II AP, located on bottomof the pneumatic block, are tapped 1⁄4 inch NPT. Output is toward thefront, supply is toward the back. Two pressure gauges, output on top,supply on bottom, are located on the front of the pneumatic block.Maximum allowable air supply pressure to the SVI II AP variesaccording to actuator, valve size, and valve type. See Pressure Droptables in valve specification sheets to determine the correct positionersupply pressure. Minimum supply pressure should be 5 to 10 psi abovemaximum spring pressure but may not exceed the rated actuatorpressure.OutputSupplyFigure 4Air Ports on Single Acting PositionerInstallation and Set Up Connecting the Tubing and Air Supply Double Acting PositionerConnect Output 1, labeled “(←I)” to the inlet port of the actuator andconnect Output 2 labeled “(←II)” to the opposing actuator port (seeFigure 5 below for double acting ports.Output I ConnectorSupply Connector Connector Output IIFigure 5Air Ports on Double Acting PositionerConnecting the Air SupplyAfter the tubing is installed, use the following procedure to connect theair supply.1.Connect a supply of clean, dry compressed air to the filterregulator.2.Turn on the air supply.3.Adjust the filter regulator.4.Supply pressure must be 5 - 10 psi greater than the springrange of the actuator but may not exceed the ratedactuator pressure. Refer to the valve or actuatorinstruction manual.Masoneilan Dresser SVI II AP Quick Start GuideWiring the SVI II AP In order for the SVI II AP to communicate the positioner data the SVI II AP must be physically connected to a HART communication. The procedure below outlines wiring the SVI II AP.Comply with current national and local regulationsfor electrical installation work.Comply with national and local explosiveatmosphere regulations.Before carrying out any work on the device, poweroff the instrument or make sure that the localeconditions for potentially explosive atmospherepermit the safe opening of the cover.Connecting to the Control LoopThe SVI II APpositioner MUST BE grounded according to localregulations. It is important to maintain correct polarity at all times,otherwise the positioner may not operate properly. The SVI II APshould be physically connected to the HART loop using a cablespecified by the HART Communication Foundation. A shielded cableis recommended.To connect the Control Loop to the SVI II AP:1.Connect one end of the cable to the control loop's4 - 20mA output2.Remove the threaded wiring covers on the positioner.3.Connect the other end of the cable to the SVI II AP. Thereare two threaded openings on the positioner. Use theopening with the red plastic insert.4.Maintain polarity + and - respectively.Wiring GuidelinesThis list contains eight guidelines for a successful implementation of DCcurrent signal, DC power, and HART communication to the SVI II AP:pliance voltage at the SVI II AP must be 9 volts at themaximum current of 20 mA.2.Signal to the SVI II AP must be a regulated current in therange 3.2 to 22 mA.3.Controller output circuit must be unaffected by the HARTtones which are in the frequency range between 1200 and2200 Hz.4.Frequency range of the HART tones must have a circuitimpedance of more than 220 Ohms, typically 250 Ohms.5.HART tones may be imposed by the positioner and acommunication device located anywhere on the signalingcircuit.Installation and Set Up Wiring the SVI II AP6.Capacitance of the signaling circuit must not exceed 0.26microfarads or 0.10 microfarads with high seriesresistance.7.Cabling must be shielded to prevent electrical noise thatwould interfere with the HART tones, with the shieldgrounded.8.Signal must be properly grounded in only one place.Note:For details and calculation methods for wiring resistance, andcapacitance and for calculation of cable characteristics pleaserefer to the HART FSK Physical Layer Specification.SVI II AP SetupsTypical system setups are shown in Figure 6 on page 13, GeneralPurpose and Explosion Proof (EEx d) Installation Schematic and Figure7 on page 13, Intrinsically Safe Installation Schematic. The SVI II APpositioner can be located in a general-purpose or hazardous areaprotected by Explosion Proof (EEx d) methods. Wiring diagrams aregeneralized, actual wiring must adhere to Electrical Installation sectionof manual and local electrical codes. The use of a HandheldCommunicator or a HART modem is not permitted in the HazardousArea protected by Explosion Proof (EEx d) methods. In Figure 7 onpage 13 the SVI II AP positioner is located in a hazardous area that isprotected by Intrinsically Safe wiring practices.The SVI II AP requires an electrical input from a 4-20 mA currentsource. The SVI II AP input signal can carry a HART communicationprotocol signal from ValVue 2.4 or greater software and a HARTmodem, or from a HART Hand Held Communicator. Since the processcontrol system, the source of the input signal, is located in a non-hazardous location, setup requires an intrinsic safety barrier be placedbetween the process control system and the SVI II AP. If the SVI II APis located in a hazardous area with Intrinsically Safe protection a barrieris not required for a flameproof installation. Alternatively the systemcan be installed as Explosion Proof ⁄ flameproof. SVI II AP cancommunicate with a remote PC running ValVue software via a modemconnected to the PC's serial or USB port. The PC, which is notintrinsically safe, must be connected to the circuit on the safe area sideof the intrinsic safety barrier if the valve is located in a hazardous area.The SVI II AP can be operated, calibrated, configured, and interrogatedeither by using local pushbutton and display, or by using a PC runningValVue 2.4 software, HART Handheld Communicator, or any registeredHART Host that supports DDs. The HART Handheld Communicator isapproved for Intrinsically Safe use in accordance with FM and ATEXstandards. Read and observe all HHC labelling. The SVI II AP ispolarity sensitive so the positive lead must be connected to the positive(+) terminal and the negative lead to the negative (-) terminal. Reversalof input will not cause damage but the unit will not function.。
