阀位变送器调试说明一、阀位变送器的接线工作原理：当输入端送入4~20mA DC电流控制执行结构，执行机构带动外接检测元件（旋转可变电阻）移动，反馈端相应输出4~20mA DC电流。

变送器可自动判别正、反作用。

第一次调试或阀门运行过程变送器输出错乱，必须重新调整，调整之前需重新认定外接可变电阻器位置，方法如下：1，输入端送入12mA电流，待阀门稳定2，将可变电阻器与阀门脱开3，旋转可变电阻器轴，用万用表测量中间引脚与两边引脚阻值，应为可变电阻器标称值的一半4，输入端电流撤除，阀门回位，将可变电阻器与阀门重新连接。

二、反向作用电流调整1、输入端外接4~20mA DC电流源，反馈端接+24VDC稳定电源，串接电流表（大于20maA），接线参考上图。

2、本变送器主要调整4~20mA DC之间的5个位置点，其余由变送器计算输出，这5个点分别是4mA DC、8mA DC、12mA DC、16mA DC、20mA DC。

送上电源（+24V），LED频闪5次，输出4 mA DC，进入调整状态（如果已经调整过则LED不频闪，如果希望重新调整，按住“CTRL”键，持续三秒钟以上，待LED开始频闪5次，立即松开按键）。

3、输入端送入4mA DC电流，确认阀门位置合适时，点动“CTRL”键，LED频闪1次，则该位置点调整完毕。

输出电流自动增加至8mA DC 4、输入端送入8mA DC电流，点动“CTRL”键，LED频闪1次，则该位置调整完毕。

输出电流自动增加至12mA DC5、依次送入12mA DC、16 mA DC并确认。

6、输入端送入20 mA D C电流，点动“CTRL”键，LED频闪8次，表示调整已完成，进入自动跟踪状态，并输出该位置点电流20 mA DC。

7、改变输入端送入电流，阀门位置改变输出电流值相应改变。

三、输出电流值调整1、由于电子元件特性的差异，每个变送器输出电流会有所不同，因此必须调整。

例如：8 mA DC位置点，输出为7.9 mA DC。

yt1000阀门定位器原理yt1000阀门定位器是一种用于调节控制阀门位置的设备，它通过测量和反馈阀门执行器的位置，实现对阀门的精确控制。

本文将介绍yt1000阀门定位器的原理及其工作过程。

一、原理概述yt1000阀门定位器基于电动阀门执行器和位置传感器的组合，实现对阀门位置的精确测量和控制。

其原理基于负反馈控制系统，通过持续的位置反馈和调整，使阀门保持在预设位置，从而实现对流体的流量和压力的精确调节。

二、工作过程1. 位置传感器yt1000阀门定位器内置了高精度的位置传感器，用于实时测量阀门执行器的位置。

SVI-II定位器和YTC定位器调试步骤与方法一、SVI-II定位器调试步骤：1、检查接线及阀门安装情况是否完整；2、切换到人工模式（Manual）；3、检查并调整好所有的结构参数（CONFIGuration）；4、运行全开、全关点（STOPS）自动搜索。

5、运行自动调整功能（autoTUNE），得到新的动态响应参数；6、检查是否有错误提示；7、手动操作看看是否可以正常运行；退出人工状态，回到自动控制状态。

菜单流程：接通信号源后，将输入信号调节到12mA。

系统会进行自检，然后进入交替显示阀位和输入信号的值。

此时系统有可能处于人工或自动的状态，取决于上次运行断电前的状态。

如果屏幕显示阀位时使用（POS-M）说明处于人工状态；如果显示阀位时使用（POS）说明处于自动状态。

然后按照流程图操作即可完成设定。

二、YTC定位器调试步骤：1、条件：①稳定的气源压力≥0.3MPa（角行程定位器压力≥0.5MPa）②4-20mA信号输入设备2、调试：①打开定位器前盖，打开电源接线盒。

②把稳定气源接入过滤减压阀并密封严紧。

③区分正负输入端接好信号输入设备。

④打开气源开关，向下调节调“0”旋钮，直至排气压力表指针不为0，然后反方向缓慢旋转调“0”旋钮，使压力表指针刚好处于0位置。

⑤输入25%（8mA）、50%（12mA）、75%（16mA）、100%（20mA）信号，观察指针下降（上升）行程：A、若单次行程超过刻度盘的1/4，说明定位器量程过大，此时应调节量程调节旋钮（先松开螺丝，然后调节下方的旋钮，向“—”方向调节。

根据实际情况确定调节的程度，单次微调，边试边调）。

B、若单次行程过小或不足刻度盘的1/4，说明定位器量程过小，操作与A相同，方向相反。

⑥每次调节量程调节旋钮后，重新进行试验，若实际行程与理论行程差距仍然很大，则再调节量程调节旋钮；若实际行程与理论行程差距较小，则调节调“0”旋钮，使指针移动到对应的刻度上，再输入信号观察指针移动是否正确。

This would cause spool(⑤) to rise upward. As the spool(⑤) rises, the air pressure will be supplied to the actuator(⑩). As the actuator's inner pressure increases, the actuator stem(⑫) will move. The movement will be transferred to cam(⑭) and pulls the span spring(⑮). The span spring(⑮)'s force will be balanced with torque motor(①), and this would cause to move flapper(②) to the normal position and reduce the gap between the nozzle(③). As the air pressure exhaustion level decreases through the nozzle(③), the pressure level in upper spool(⑤) increases again. The spool(⑤) would come back to the normal position and block the seat(⑦) which would lead to block the supply air from the actuator(⑩). When the actuator(⑩) stops the movement, the positioner would come back to the normal position. <Figure 1>Suffix SymbolYT-1000L series follows suffix symbols as follows.YT-1000L════════════════════════════════Motion Type S :LinearD :Double════════════════════════════════Explosion Proof m :Ex dm IIB T5C :Ex dm IIC T5:Ex ia IIB T6in :Non-Explosion════════════════════════════════Feedback Lever 1 :10 ~ 40mm:30∼ 70mm23 :60 ∼ 100mm4 : 100 ∼ 150mm════════════════════════════════Orifice 1 : Ø1Ø22:3 : None════════════════════════════════Connection Type 1 :PT2 :NPT════════════════════════════════Ambient Temperature S :-20 ~ 70℃H :-20 ~ 120℃L :-40 ~ 70℃════════════════════════════════* For special specification, please contact our sales department.Specification* Tested under ambient temperature of 20℃, absolute pressure of 760mmHg, and humidity of 65%.Please contact us for more detailed specification.* 1: For 1/2 Split Control, it can be applied by adjusting zero and span.*2: For inquiry regarding strokes under 10mm or above 150mm, please contact YTC.* 3: YT-1000L has different types of explosion proof certificates.

YTC定位器调试步骤：
1、条件：
①稳定的气源压力≥0.3MPa（角行程定位器压力≥0.5MPa）
②4-20mA信号输入设备
2、调试：
①打开定位器前盖，打开电源接线盒。

②把稳定气源接入过滤减压阀并密封严紧。

③区分正负输入端接好信号输入设备。

④打开气源开关，向下调节调“0”旋钮，直至排气压力表指针不为0，然后反方向缓慢旋转调“0”旋钮，使压力表指针刚好处于0位置。

⑤输入25%（8mA）、50%（12mA）、75%（16mA）、100%（20mA）信号，观察指针下降（上升）行程：
A、若单次行程超过刻度盘的1/4，说明定位器量程过大，此时应调节量程调节旋钮（先松开螺丝，然后调节下方的旋钮，向“—”方向调节。

根据实际情况确定调节的程度，单次微调，边试边调）。

B、若单次行程过小或不足刻度盘的1/4，说明定位器量程过小，操作与A相同，方向相反。

⑥每次调节量程调节旋钮后，重新进行试验，若实际行程与理论行程差距仍然很大，则再调节量程调节旋钮；若实际行程与理论行程差距较小，则调节调“0”旋钮，使指针移动到对应的刻度上，再输入信号观察指针移动是否正确。

注：通过量程调节旋钮和调“0”旋钮的配合来调节量程和行程，已达到调试的目的。

注意事项：
（1）当输入信号为20mA时，定位器排气压力必须＞3公斤（球阀5公斤），一般为3.2-4公斤。

若压力不足则调节阀开启/关闭不严，无法正常工作。

（2）气开阀：当输入信号为0时，排气压力必须为0，否则阀门没有完全关闭。

Any changes in the product’sspecification, structure and/or any componentsmay not result in an immediate revised version ofthe manual.∙ The manual should not be duplicated orreproduced for any purpose without the approvalof CVS Controls Ltd.MANUFACTURER WARRANTY-For safety, it is imperative to follow instructions in the manual. The manufacturer is not liable for any damages caused by the users negligence.-The manufacturer is not liable for any damages or accidents as a result of alterations or modifications made to the product or parts. If alterations or modifications are required, please contactCVS Controls Ltd.-The manufacturer warrants the product from the original date of purchase for one (1) year, except as otherwise stated.-The manufacturer warranty will be considered void should the product be subjected to abuse, faulty installation, lack of reasonable care, repair or service in any way, that is not contemplated in the documentation of the product, or if the model or serial number has been altered, tampered with, defaced, or removed; damages that occur in shipment, due to the act of God, failure due to power surge, and cosmetic damage. Improper or incorrectly performed maintenance also voids the Limited Warranty.PRODUCT DESCRIPTIONMain Features and Functions∙ It is designed for high durability and performance in high vibration environments.∙ Proven Durability.∙ Short and accurate response time.∙ Simple part change can set a 1/2 Split Range.∙ Economical due to less air-consumption.∙ Direct/Reverse action can be easily set.∙ Simple zero and span adjustment process.∙Easy feedback connection.CVS Controls Ltd.Product Manual: CVS Rack & Pinion ActuatorOperation LogicAs the input signal is increased, the flapper (2) get pushed by the force of the torque-motor (1). As the gap between the flapper (2) and the nozzle (3) increases, air pressure bleeds from the pilot valve (4) and the spool (5). As a result, the spool (5) rises and simultaneously opens the seat (7). This allows air pressure to discharge through port OUT1 to the actuator (10). As the actuators inner pressure increases, the actuator stem (12) will move, pushing on the feedback lever (13). This movement is transferred to the cam (14) and pulls on the feedback spring (16). At the point of balanced force exerted by the input signal and the feedback spring, the gap between the flapper (2) and the nozzle (3) will decrease, stopping the movement to the actuator.CVS Controls Ltd.Product Manual: CVS Rack & Pinion Actuator Specification* 1: For 1/2 Split Control, it can be applied by adjusting zero and span.* 2: For inquiries regarding strokes under 10mm or above 150mm, please contact CVS Controls Ltd.Parts and AssemblyDimensionsCVS Controls Ltd.Product Manual: CVS Rack & Pinion ActuatorZERO UNIT TORQUE MOTOR BASE BODY JUNCTION BOXCOVER PILOT VALVE FEEDBACK SHAFT SPAN UNITVENT UNIT FEEDBACK LEVER224.3132.36 Conduit EntryPT(NPT) 1/2 PF(G) 1/2Out 2NONE45122166.2-M8x1.25P452327 32.54-M8x1.25P35.591.8837.280.253326.543.5GaugePT(NPT) 1/8OUT 1PT(NPT) 1/4SupplyPT(NPT) 1/4INSTALLATIONSafety WarningWhen installing the positioner, please ensure you read and follow the safety instructions.∙ All input and supply pressure to valve, actuator, and other related devices must be turned off.∙ Use the bypass valve or other equipment to avoid an entire system “shut down”.∙ Make sure there is no remaining pressure in the actuator.YT-1000L InstallationYT-1000L should be installed on a linear motion valve such as a globe or gate valve using a spring return type diaphragm or piston actuator. Before installation, be sure to check for the following installation components.1. YT-1000L main body2. Feedback lever and lever spring3. Flange nut (bottom side of YT-1000L)4. 4 pcs. of hexagon head bolts (M8 X 1.25P)5. 4 pcs. of M8 plate washerInstallation Steps:1. A proper bracket must be made in order to attach the positioner on the actuator yoke. Please consider the following when making a bracket.i) Feedback level should be leveled at 50% of the valve stroke. (Refer to step 7.)ii) Feedback lever connection bar of actuator clamp should be installed at the position that the valve stroke and number, indicated on the feedback, should be fitted. (Refer to step 8.)2. Attach YT-1000L to the bracket, which was produced in the earlier step, by using bolts. (Figure 2) Please refer to the backside of the product for size of bolts. The standard size of bolt is M8 X 1.25P.3. Attach YT-1000L (with bracket) to the actuator yoke. DO NOT TIGHTEN COMPLETLEY.4. Connect YT-1000L feedback lever to the actuator clamp. The gap on the YT-1000L feedback lever is6.5mm. The connection bar thickness should be less than 6.3mm. (Figure 3)5. Connect the air filter regulator to the actuator tem-porarily. Set supply pressure of the regulator in orderto position the actuator clamp at 50% of the valve stroke.(Figure 4 next page)CVS Controls Ltd.Product Manual: CVS Rack & Pinion ActuatorMax.6.36.5mm506. Insert connection bar into the YT-1000L feedback lever. The connection bar should be inserted at the 50% point on the feedback lever, which would help to reduce hysteresis.(Figure 5)7. If the connection bar does not point at the 50% point, then adjust the bracket or feedback link bar position. Failure to position at 50% would lower the linearity of the positioner.(Figure 6) 8. Check valve stroke. The stroke numbers are indicated on the feedback lever. Position the connection bar at the number on the feedback lever according to the valve stroke. To adjust, move the bracket or connection bar.(Figure 7)Stroke 70mmNOTE: After installing the YT-1000L, operate the valve from 0% to 100% stroke by using the air filter regulator on the actuator. Both at 0% and 100%, the feedback lever should not touch the lever stopper, which is located on the backsideof the YT-1000L.(Figure 8)If the feedback lever touches the lever stopper, YT-1000L should be installed further away from the center of the yoke.9. After the proper installation, tighten all the bolts on the bracket, the feedback lever, and the connectionbar.CVS Controls Ltd.Product Manual: CVS Rack & Pinion ActuatorYT-20040 50 6050%90°20 30 40 50 6040 50 60 70 20 3070 Stroke 30mmPIPING CONNECTIONNOTE:To avoid moisture, oil, or dust from entering the product, please carefully select the supplypressure compressor.Supply Pressure Condition1. Dry air with at least 10°C lower than ambient temperature.2. Keep away from dusty air. Filter can only sort 5 micron or larger.3. Avoid oil.4. Comply with ANSI/ISA-57.3 1975(R1981).5. Not to be used beyond the range of1.4 - 7 kgf/cm2 (20 - 100 Psi).6. Set air filter regulator’s supplied pressure 10% higher than actuator’s spring range pressure.Pipe Condition1. Make sure the inside of the pipe is empty.2. Do not use pipeline that is squeezed or has holes.3. To maintain flow rate, use the pipeline that has more than a 6mm inner diameter.4. Do not use an extremely long pipeline system. It may affect flow rate due to the friction inside the pipeline.Piping Connection with ActuatorYT-1000 series single acting type is set out to use OUT1 port. OUT1 port should be connected with the supply pressure port from the actuator when using single acting type spring return actuator. For double acting, the piping connection can be changed due to the operation direction. Please refer to the following diagrams when piping.(Figures 9 - 11)CVS Controls Ltd.Product Manual: CVS Rack & Pinion ActuatorOUT1OUT1SUP.AIRSUPPLYYT-200OUTAIRSUPPLYYT-200OUTOUT 1OUT 2OUT 2 SUP.OUT 1OUT 1OUT 2AIRSUPPLYAIRSUPPLYOUT 2SUP.

Make sure to fasten the connection.3. Close the terminal box cover. (Figure15)ADJUSTMENTAdjustment - Zero Point1. Set supply signal at 4mA or 20mA and rotate adjuster clockwise or counter-clockwise to adjust the actuator’s initial point. When setting the initial point, the specification of valve and system must be taken into account. Please refer to Figure 17 for increase/decrease of the zero point.2. When a single acting actuator with spring is used, please check if the pressure level, which is indicated on the positioner, is the same as the supplied pressure level.CVS Controls Ltd.Product Manual: CVS Rack & Pinion ActuatorUpper SideLower SideGroundRed (+)Black (-)Adjustment - Span1. After setting zero, supply 20mA or 4mA of signal. Check the actuator’s stroke. If the stroke is too low, adjust the span towards the (+) direction.If the stroke point is too high, adjust the span towards the (-) direction. (Figure 18)2. Changing span points affects the zero point setting, so the zero setting must be set again. After setting zero point, confirm the span point. This step must be repeated until both points are properly set.3. After setting is completed, tighten lock screw.Adjustment - A/M Switch (Auto/Manual) 1. A/M switch adjusts the valve operation to automatic or manual.2. When produced, YT-1000L is set at “A(Automatic)”. If user prefers the positioner setting as “M(Manual)”, the setting can be changed by turning the switch counter-clockwise. (Figure 19)3. If it is set as “M(Manual)”, the air pressure will be supplied to the actuator directly. Always set back to “A(Automatic)” after setting change.4. If OUT2 in single acting actuator or double acting actuator is used, the A/M switch will not operate. Adjustment - Seat Adjuster1. Seat adjustment is set according to the customers request before the positioner is delivered. Please do not adjust the seat adjuster.2. Seat adjuster is always used for double acting actuators and adjusted when the pressure balance point must be changed. Please do not touch the seat adjuster, because it can affect the positioner’s performance.Adjustment - Orifice1. If the size of the actuator is too small relative to the flow rate, the positioner can have hunting. In order to avoid hunting, orifice can be used. There are three types of orifice.CVS Controls Ltd.Product Manual: CVS Rack & Pinion ActuatorLock ScrewAuto Manual SwitchOutputPressureOutputPressureOutputPressureHigh Pressure Balance(0.9~1.0Ps) - NormalMed.

Remove the o-ring from OUT1 and OUT2 port and insert appropriate orifice. After inserting orifice, replace the o-ring. Make sure there are not any substances entering into the port. (Figure 21)3. If hunting persists after inserting the orifice, please contact CVS Controls Ltd. or its appropriate agent.TROUBLESHOOTING►Positioner does not respond to the inputsignal.1. Check supply pressure level. The lever must be at least 1.4 kgf/cm2. For spring return type actuator, the supply pressure level has to be larger than the spring’s specification.2. Check if the input signal is properly supplied to the positioner. The signal should be 4~20mA DC.3. Check if zero pint or span point is properly set.4. Check if the positioners nozzle has been blocked. Also, check if the pressure is supplied tothe positioner and the pressure is being exhausted through the nozzle. If the nozzle has been blocked by any substances, please send the product for repair. 5. Check if the feedback lever has been installed properly.►The pressure of OUT1 reaches exhaustingpressure level and does not decrease.1. Check A/M Switch. If the switch has been damaged,replace the switch or pilot relay valve.2. Check for a gap or damages between the nozzle and the flapper. If damaged, pleae contact CVS Controls Ltd.►The pressure is exhausted only by the A/Mswitch.1. Check if the positioners nozzle has been blocked. Also, check if the pressure is supplied to the positioner and the pressure is being exhausted through the nozzle. If the nozzle has been blocked by any substances, please contact CVS Controls Ltd.►Linearity is too low1. Check if the positioner is properly positioned. Especially if the feedback lever is parallel to the ground at 50% point.2. Check if zero and span point have been properly adjusted. If either one of the values is being adjusted, another one must be adjusted as well.3. Check if the supply air pressure level is stable from the regulator. If the level is unstable, the regulator must be replaced.►Hysteresis is too low1. In case of a double acting actuator, check if seat adjustment has been properly performed.

B、若单次行程过小或不足刻度盘的1/4，说明定位器量程过小，操作与A相同，方向相反。

⑥每次调节量程调节旋钮后，重新进行试验，若实际行程与理论行程差距仍然很大，则再调节量程调节旋钮；若实际行程与理论行程差距较小，则调节调“0”旋钮，使指针移动到对应的刻度上，再输入信号观察指针移动是否正确。

注：通过量程调节旋钮和调“0”旋钮的配合来调节量程和行程，已达到调试的目的。

注意事项：
（1）当输入信号为20mA时，定位器排气压力必须＞3公斤（球阀5公斤），一般为3.2-4公斤。

若压力不足则调节阀开启/关闭不严，无法正常工作。

（2）气开阀：当输入信号为0时，排气压力必须为0，否则阀门没有完全关闭。
