The electronic module processor within the positioner reads the input control signal and the valve position feedback signal. After digital processing, it converts these signals into an analog control drive signal for the I\/P electrical converter. The I\/P converter then transforms the electrical signal into a pneumatic signal, which is power amplified by a pneumatic amplifier, providing two pneumatic outputs.<\/span><\/span><\/p>\n\n<figure><img alt=\"principle of the dvc6200 double acting digital positioner\" decoding=\"async\" height=\"389\" loading=\"lazy\" sizes=\"(max-width: 579px) 100vw, 579px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner-jpg.webp\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner-jpg.webp 579w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner-300x202.webp 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner-64x43.webp 64w\" width=\"579\" \/><\/span><\/span>\n\n<figcaption>principle of the dvc6200 double acting digital positioner<\/span><\/span><\/figcaption>\n<\/figure>\n\nFor instance, as the signal increases, the air pressure at output A increases while the air pressure at output B decreases. When the signal is set to 12mA, the air pressures at outputs A and B are approximately equal. Conversely, when the signal decreases, the air source at output B increases, and the air source at output A decreases. The pneumatic output from the digital valve positioner is then directed to the pneumatic actuator of the control valve, causing the valve stem position to change. Consequently, the position of the magnetic strip also changes. A Hall sensor detects this change in valve position and sends the signal back to the electronic module. The positioning control process concludes when the valve position aligns with the input control signal, stabilizing the signal from the I\/P electrical converter and the output air pressure from the pneumatic amplifier, with minimal deviation.<\/span><\/span><\/p>\n\n<figure><img alt=\"principle of the dvc6200 double acting digital positioner3\" decoding=\"async\" height=\"407\" loading=\"lazy\" sizes=\"(max-width: 1024px) 100vw, 1024px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-1024x407.webp\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-1024x407.webp 1024w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-300x119.webp 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-768x305.webp 768w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-600x238.webp 600w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-64x25.webp 64w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-jpg.webp 1080w\" width=\"1024\" \/><\/span><\/span>\n\n<figcaption>principle of the dvc6200 double acting digital positioner3<\/span><\/span><\/figcaption>\n<\/figure>\n\n<h4>Difference of Digital Positioner DVC6200 Terminal Box with Feedback Signal or Not<\/span><\/span><\/h4>\n\n<figure><img alt=\"dvc6200 double acting digital positioner with feedback\" decoding=\"async\" height=\"410\" loading=\"lazy\" sizes=\"(max-width: 433px) 100vw, 433px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-with-feedback-jpg.webp\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-with-feedback-jpg.webp 433w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-with-feedback-300x284.webp 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-with-feedback-64x61.webp 64w\" width=\"433\" \/><\/span><\/span>\n\n<figcaption>dvc6200 double acting digital positioner with feedback<\/span><\/span><\/figcaption>\n<\/figure>\n\n<figure><img alt=\"dvc6200 double acting digital positioner without feedback\" decoding=\"async\" height=\"315\" loading=\"lazy\" sizes=\"(max-width: 356px) 100vw, 356px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-without-feedback-jpg.webp\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-without-feedback-jpg.webp 356w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-without-feedback-300x265.webp 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-without-feedback-64x57.webp 64w\" width=\"356\" \/><\/span><\/span>\n\n<figcaption>dvc6200 double acting digital positioner without feedback<\/span><\/span><\/figcaption>\n<\/figure>\n\n<h3 id=\"The_IP_Electrical_Converter—Transforms_Electrical_Signals_into_Pneumatic_Signals\">The I\/P Electrical Converter&mdash;Transforms Electrical Signals into Pneumatic Signals<\/span><\/span><\/h3>\n\nThe air supply passes through a constant throttle orifice (constant air resistance) to the nozzle. The drive signal from the electronic module controls the coil of the I\/P converter, attracting the armature to act. This movement of the armature moves the flapper closer to the nozzle, causing an increase in the back pressure at the nozzle. This increase translates to a higher pneumatic signal sent to the pneumatic amplifier, ultimately resulting in an increase in the output air pressure from the valve positioner. When the drive signal is reduced, the electromagnetic coil causes the armature\/flapper to move away from the nozzle, reducing its back pressure and, consequently, the output from the pneumatic amplifier decreases.<\/span><\/span><\/p>\n\n&nbsp;<\/p>\n\n<h2 id=\"How_to_Install_Fisher_Digital_Positioner_DVC6200_\">How to Install Fisher Digital Positioner DVC6200<\/span><\/span><\/h2>\n\n<h3 id=\"How_to_Install_and_Assembly_DVC6200_to_Sliding_StemLinear_Type_Control_Valves\">How to Install and Assembly DVC6200 to Sliding Stem\/Linear Type Control Valves<\/span><\/span><\/h3>\n\n<figure><img alt=\"Play: Video\" aria-label=\"Play: Video\" id=\"fallbackPlaceholder\" loading=\"lazy\" referrerpolicy=\"origin\" src=\"https:\/\/i.ytimg.com\/vi\/SBr99gejyII\/hqdefault.jpg\" \/><button aria-label=\"Play: Video\" id=\"playButton\"><\/button><\/span><\/span>\n\n<figcaption>Resource from&nbsp;Fisher Valves &amp; Instruments<\/strong><\/span><\/span><\/figcaption>\n<\/figure>\n\n<figure><img alt=\"mounting the dvc6200 digital valve controller1\" decoding=\"async\" height=\"335\" loading=\"lazy\" sizes=\"(max-width: 796px) 100vw, 796px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1.png\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1.png 796w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1-300x126.png 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1-768x323.png 768w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1-600x253.png 600w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1-64x27.png 64w\" width=\"796\" \/><\/span><\/span><\/figure>\n\n<figure><img alt=\"mounting the dvc6200 digital valve controller2\" decoding=\"async\" height=\"321\" loading=\"lazy\" sizes=\"(max-width: 784px) 100vw, 784px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2.png\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2.png 784w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2-300x123.png 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2-768x314.png 768w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2-600x246.png 600w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2-64x26.png 64w\" width=\"784\" \/><\/span><\/span><\/figure>\n\n<figure><img alt=\"mounting the dvc6200 digital valve controller3\" decoding=\"async\" height=\"339\" loading=\"lazy\" sizes=\"(max-width: 784px) 100vw, 784px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3.png\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3.png 784w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3-300x130.png 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3-768x332.png 768w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3-600x259.png 600w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3-64x28.png 64w\" width=\"784\" \/><\/span><\/span><\/figure>\n\n<h3 id=\"How_to_Install_and_Assembly_DVC6200_to_Rotary_Type_Control_Valves\">How to Install and Assembly DVC6200 to Rotary Type Control Valves<\/span><\/span><\/h3>\n\n<figure><img alt=\"Play: Video\" aria-label=\"Play: Video\" id=\"fallbackPlaceholder\" loading=\"lazy\" referrerpolicy=\"origin\" src=\"https:\/\/i.ytimg.com\/vi\/bApJdlDl8To\/hqdefault.jpg\" \/><button aria-label=\"Play: Video\" id=\"playButton\"><\/button><\/span><\/span>\n\n<figcaption>Resource from&nbsp;Fisher Valves &amp; Instruments<\/strong><\/span><\/span><\/figcaption>\n<\/figure>\n\n<h2 id=\"How_use_375_or_475_Field_communicator_to_Calibrate_Fisher_DVC6200_Digital_Positioner\">How Use 375 Or 475 Field Communicator To Calibrate Fisher DVC6200 Digital Positioner<\/span><\/span><\/h2>\n\n<h3 id=\"Step_1_Initial_Connection\">Step 1.

This is a true digital control method, where piezo valves, similar to very small solenoid valves, are used to control loading and exhausting air, to and from the positioner. As such, the tuning parameters listed below are based upon this control method.<\/span><\/span><\/p>\n\nAdjustable Tuning Parameters Descriptions:<\/span><\/span><\/p>\n\n<ul>\n\t<li>[IMPUP] &amp; [IMPDN]: Impulse Length UP and DOWN<\/span><\/span><\/li>\n<\/ul>\n\n-These tuning parameters are similar to gain. They represent the minimum time the piezo valves will cycle; units are in milliseconds- ms. For example; if the value is 10 ms, the fastest the piezo valves will cycle is 10 ms, not any faster. Therefore, an increase in these values will increase the gain response. The range is 2.0 to 160 ms.<\/span><\/span><\/p>\n\n<ul>\n\t<li>[SSUP] &amp; [SSDN]: Short Step Zone<\/span><\/span><\/li>\n<\/ul>\n\nThese tuning parameters are similar to integral action. Essentially there are two actions of the piezo valves- long pulses and quick\/short pulses. The values are in percent of total stroke. When the position of the valve is within this Short Step Zone of the setpoint value, the positioner will begin the short pulses of the piezo valves. For example, if the current short step zone is 10 % and the positioner is given a step change from 0 to 50 %, the piezo valves are held wide open (long pulse) until the valve gets to within 10 % of the setpoint. Therefore, once the valve is at 40 %, the piezo valves will produce short\/quick pulses, to prevent overshoots. The smaller the value, the faster the response.<\/span><\/span><\/p>\n\n<ul>\n\t<li>[PRUP] &amp; [PRDN]: Prediction Up and Down<\/span><\/span><\/li>\n<\/ul>\n\n-These tuning parameters are similar to derivatives. This predicts the movement of the valve. The smaller the number, the less prediction is used, thus faster response. The range is 1 to 40.<\/span><\/span><\/p>\n\nHow to customize tuning parameters:<\/strong><\/span><\/span><\/p>\n\n<ul>\n\t<li>Enter Diagnostic Mode:<\/strong><\/span><\/span><\/li>\n<\/ul>\n\n-When the device is in Auto mode, press and hold all three buttons down at the same time:<img alt=\"button1\" decoding=\"async\" height=\"36\" loading=\"lazy\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2022\/06\/button1.jpg\" width=\"38\" \/><img alt=\"button2\" decoding=\"async\" height=\"32\" loading=\"lazy\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2022\/06\/button2.jpg\" width=\"35\" \/><img alt=\"button3\" decoding=\"async\" height=\"28\" loading=\"lazy\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2022\/06\/button3.jpg\" width=\"30\" \/>.<\/span><\/span><\/p>\n\n-Diagnostic name is shown in the lower right of the display.<\/span><\/span><\/p>\n\nEdit Tuning Value:<\/strong><\/span><\/span><\/p>\n\n-Go to the desired diagnostic parameter by pressing and releasing button.

For example, if the deadband value is 0.1 %, and the setpoint is 70 %, the PS2 will work the piezo valves to get within the following position range: 69.9 % to 70.1 %. Thus, the PS2 will continuously work to get within this deadband range. However, if the mechanics of the actuator and\/or valve cannot achieve this precise position, the PS2 will continuously hunt or oscillate around the setpoint position.<\/span><\/span><\/p>\n\nThere are two settings for the PS2 deadband: &ldquo;Auto&rdquo; or a fixed numerical value<\/span><\/span><\/p>\n\n<ul>\n\t<li>When configuration parameter &ldquo;DEBA&rdquo; = &ldquo;Auto&rdquo;, the deadband value is dynamic and changes per the process conditions. In other words, the deadband value changes if stiction or oscillation is detected. For example, the deadband value will increase when mechanical issues are detected. Additionally, the PS2 will periodically decrease the deadband value to try and achieve precise valve positioning. The deadband value changes in 0.1 % increments.<\/span><\/span><\/li>\n\t<li>Thus, only a fixed deadband value can be too small.<\/span><\/span><\/li>\n\t<li>Too small a deadband can cause valve oscillation and indicate.<\/span><\/span><\/li>\n<\/ul>\n\nChange Deadband Setting:<\/strong><\/span><\/span><\/p>\n\n<ul>\n\t<li>From AUT or MAN mode, press&nbsp;<img alt=\"button1\" decoding=\"async\" height=\"36\" loading=\"lazy\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2022\/06\/button1.jpg\" width=\"38\" \/>button for 5 seconds.

For example, if the smallest movement that can be achieved is 0.8 %, then this is the best the valve assembly can move- in 0.8% increments. Therefore trying to achieve smaller movements is impossible and will result in oscillations.<\/span><\/span><\/li>\n\t<li>Oscillations can be reduced by setting the Deadband value to &ldquo;Auto&rdquo;<\/span><\/span><\/li>\n<\/ul>\n\n<h3 id=\"25_Supply_Air_Too_High\"> \n25 Supply Air Too High<\/span><\/span><\/h3>\n\n<h4>Symptoms<\/span><\/span><\/h4>\n\n<ul>\n\t<li>Oscillation\/hunting<\/span><\/span><\/li>\n\t<li>Valve action is too fast<\/span><\/span><\/li>\n<\/ul>\n\nMaximum air pressure ratings are indicated on the actuator&rsquo;s nameplate\/stamp.

The most common failure is a result of poor air quality, which can include moisture. In addition to an air drying system, it is recommended to install a coalescent filter on the supply line, directly upstream of the positioner. Siemens offers an Air Coalescing Filter, Model 2306, which removes dirt, oil, moisture, and other impurities from the instrument-air supply. \nIn addition, exceeding the recommended supply pressure will damage the valve block. The maximum pressure rating for the PS2 is: 101 psi (7 bar), see Supply Air Too High (Page 50). \nIt is recommended to install a regulator on the supply line, upstream from the positioner, and to regulate supply pressure so it does not exceed the maximum pressure rating of the PS2 and the actuator. Siemens offers a filter regulator, Model 91H, which regulates pressure and removes debris.<\/span><\/span><\/p>\n\nValve Block Testing<\/strong><\/span><\/span><\/p>\n\nThe following tests will refer to gauges on the supply and output(s) of pneumatic lines. If the PS2 does not have a gauge block, consider temporary gauge installation (inline) for diagnostic purposes.

In chemical production, process operators often describe that the control valve can&rsquo;t be closed and there is a large leakage, which affects the operation, we can use this function to meet the needs of the process as much as possible without replacing the control valve.<\/span><\/span><\/p>\n\n<h3 id=\"Case_2_The_flow_curve_of_the_control_valve_is_not_ideal\">Case 2: The flow curve of the control valve is not ideal<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nSIPART PS2 valve positioner parameter 12SFCT item, built-in six common&nbsp;<a data-id=\"https:\/\/cncontrolvalve.com\/why-do-different-control-valves-have-different-characteristics\/\" data-type=\"URL\" href=\"https:\/\/cncontrolvalve.com\/why-do-different-control-valves-have-different-characteristics\/\">flow characteristics<\/a>&nbsp;of control valves and user-defined flow characteristics, each control valve has its inherent flow characteristics, usually, this parameter of the positioner can follow the inherent flow characteristics of the control valve as long as it is set to Lin. If the flow characteristics of the control valve do not match the process requirements, the overall flow characteristics of the control valve can be changed through the setting of parameter 12SFCT. In short, the flexible setting of parameter 12SFCT can meet the process requirements according to the actual situation.<\/span><\/span><\/p>\n\n<h3 id=\"Case_3_Control_valve_action_direction_is_not_consistent_with_the_requirements\">Case 3: Control valve action direction is not consistent with the requirements<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nThis is related to the setting of the two parameters 7SDIR and 38YDIR of the valve positioner. The 7SDIR item is the direction set point, and the setting of the 7SDIR item determines the lifting and lowering of the actuator when the positioner receives the 4~20mA signal.<\/span><\/span><\/p>\n\nThe 38YDIR item is the travel direction display, which shows the lift of the actuator. By comparing with the actual switching direction of the control valve and the signal output from the control room, the parameter 7SDIR and parameter 38YDIR can be set correctly. when determining the switching direction of the control valve, it is necessary to cooperate with the process personnel, especially for the rotary type control valve, when the indication mark of the actuator is not clear, it is easy to misjudge the switching and cause production accidents, which must be taken seriously.<\/span><\/span><\/p>\n\n<h3 id=\"Case_4_Siemens_SIPARTPS2_positioner_initialization_stops_at_RUN5_and_does_not_reach_Finish_waiting_time_5min\">Case 4: Siemens SIPARTPS2 positioner initialization stops at RUN5 and does not reach Finish (waiting time &gt;5min)<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nThe cause of this fault is the installation of the positioner, actuator, and other components. You can check the installation of the positioner, actuator, and feedback part, correct the problem in time, re-assemble it and then initialize it to see if the initialization time can be shortened<\/span><\/span><\/p>\n\n<h3 id=\"Case_5_Siemens_SIPARTPS2_positioner_stops_at_RUN3_during_initialization\">Case 5: Siemens SIPARTPS2 positioner stops at RUN3 during initialization<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nThe reason for this fault is that the actuator takes too long to position. We observe whether the actuator switching time can be reduced by opening the restrictor completely or adjusting the pressure PZ (air pressure) to the high allowed value. You can also use a booster to increase the actuator force and shorten the switching time.<\/span><\/span><\/p>\n\n<h3 id=\"_Case_6_When_Siemens_SIPARTPS2_positioner_initializes_it_stops_at_RUN2_and_cannot_proceed_\">Case 6: When Siemens SIPARTPS2 positioner initializes, it stops at RUN2 and cannot proceed<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nDue to the high adaptive capability of the Siemens SIPARTPS2 positioner, it can work with linear and rotary type actuators with different travels. The positioner needs to set the parameters corresponding to the stroke during initialization so that the potentiometer detects the displacement of the actuator and the positioner drives the actuator action according to this displacement signal. If it stops at RUN2 during initialization, it is possible that the parameter setting is not reasonable. You can change the feedback shaft rotation angle in parameter 2YAGL of the valve positioner, changing 33&deg; to 90&deg;, and then initialize it again to see if it is successful. If the rotation angle of the feedback shaft is smaller than the small rotation angle, the initialization will not be successful. The feedback shaft rotation angle can be set as follows: set 33&deg; when the stroke of the linear actuator is less than 20mm. Set 90&deg; when the stroke of the linear actuator is more than 20mm. Set 90&deg; automatically for the rotary type control valve.<\/span><\/span><\/p>\n\nIn addition, the stroke or angle of the actuator can also be adjusted manually. Manually adjusting the actuator stroke to the start and end positions can complete the step of RUN2. It is not necessary to automatically find the starting point of the actuator during the initialization of the positioner. So when automatic initialization is not possible, manual initialization is selected to enable the control valve to be adjusted.<\/span><\/span><\/p>\n\n<h3 id=\"Case_7_The_positioner_makes_a_sound_of_puffing_and_the_control_valve_produces_a_vibration\">Case 7: The positioner makes a sound of puffing, and the control valve produces a vibration<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nThis is because of the positioner air tubing leakage, use soap water to detect the positioner outlet air pipeline and the connection of the actuator air source, find the leakage that the problem will be solved.<\/span><\/span><\/p>\n\n<h3 id=\"Case_8_Control_valve_maintenance_and_the_control_accuracy_has_problems\">Case 8: Control valve maintenance and the control accuracy has problems<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nAfter maintenance of the control valve, due to changes in the positioner, valve stem, and feedback part, it must be initialized before the positioner and actuator can match each other and drive the actuator to act as a required control signal. The automatic initialization process of the Siemens SIPART PS2 valve positioner consists of five steps, which you can follow step by step for each task.<\/span><\/span><\/p>\n\n<ul>\n\t<li>Step 1, Determine whether the valve positioner is positive or negative actions and the LCD shows RUN1.<\/span><\/span><\/li>\n\t<li>Step 2, determine the starting point and range of the valve positioner, the LCD will show RUN2.<\/span><\/span><\/li>\n\t<li>Step 3, Determine the positioning time of the actuator, the LCD will show RUN3.<\/span><\/span><\/li>\n\t<li>Step 4, determine the valve positioning increment value, the LCD shows RUN4.<\/span><\/span><\/li>\n\t<li>Step 5, optimize the dynamic response of the actuator, and the LCD will display RUN5.<\/span><\/span><\/li>\n<\/ul>\n\nAfter completing the above five steps, the LCD will display Finish to complete the automatic initialization process and the valve positioner can work normally<\/span><\/span><\/p>\n\n<h3 id=\"Case_9_PS2_Smart_positioner_didn’t_work\">Case 9: PS2 Smart positioner didn&rsquo;t work<\/span><\/span><\/h3>\n\nTrouble Description: Single-acting valve positioner with HART function is used with a&nbsp;<a data-id=\"https:\/\/cncontrolvalve.com\/product-category\/butterfly-valves\/\" data-type=\"URL\" href=\"https:\/\/cncontrolvalve.com\/product-category\/butterfly-valves\/\">butterfly valve<\/a>&nbsp;(rotary type), the field failure is shown as when the input current signal is 15mA, the valve suddenly opens.

The electronic module processor within the positioner reads the input control signal and the valve position feedback signal. After digital processing, it converts these signals into an analog control drive signal for the I\/P electrical converter. The I\/P converter then transforms the electrical signal into a pneumatic signal, which is power amplified by a pneumatic amplifier, providing two pneumatic outputs.<\/span><\/span><\/p>\n\n<figure><img alt=\"principle of the dvc6200 double acting digital positioner\" decoding=\"async\" height=\"389\" loading=\"lazy\" sizes=\"(max-width: 579px) 100vw, 579px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner-jpg.webp\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner-jpg.webp 579w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner-300x202.webp 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner-64x43.webp 64w\" width=\"579\" \/><\/span><\/span>\n\n<figcaption>principle of the dvc6200 double acting digital positioner<\/span><\/span><\/figcaption>\n<\/figure>\n\nFor instance, as the signal increases, the air pressure at output A increases while the air pressure at output B decreases. When the signal is set to 12mA, the air pressures at outputs A and B are approximately equal. Conversely, when the signal decreases, the air source at output B increases, and the air source at output A decreases. The pneumatic output from the digital valve positioner is then directed to the pneumatic actuator of the control valve, causing the valve stem position to change. Consequently, the position of the magnetic strip also changes. A Hall sensor detects this change in valve position and sends the signal back to the electronic module. The positioning control process concludes when the valve position aligns with the input control signal, stabilizing the signal from the I\/P electrical converter and the output air pressure from the pneumatic amplifier, with minimal deviation.<\/span><\/span><\/p>\n\n<figure><img alt=\"principle of the dvc6200 double acting digital positioner3\" decoding=\"async\" height=\"407\" loading=\"lazy\" sizes=\"(max-width: 1024px) 100vw, 1024px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-1024x407.webp\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-1024x407.webp 1024w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-300x119.webp 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-768x305.webp 768w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-600x238.webp 600w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-64x25.webp 64w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Principle-of-the-DVC6200-Double-Acting-Digital-Positioner3-jpg.webp 1080w\" width=\"1024\" \/><\/span><\/span>\n\n<figcaption>principle of the dvc6200 double acting digital positioner3<\/span><\/span><\/figcaption>\n<\/figure>\n\n<h4>Difference of Digital Positioner DVC6200 Terminal Box with Feedback Signal or Not<\/span><\/span><\/h4>\n\n<figure><img alt=\"dvc6200 double acting digital positioner with feedback\" decoding=\"async\" height=\"410\" loading=\"lazy\" sizes=\"(max-width: 433px) 100vw, 433px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-with-feedback-jpg.webp\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-with-feedback-jpg.webp 433w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-with-feedback-300x284.webp 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-with-feedback-64x61.webp 64w\" width=\"433\" \/><\/span><\/span>\n\n<figcaption>dvc6200 double acting digital positioner with feedback<\/span><\/span><\/figcaption>\n<\/figure>\n\n<figure><img alt=\"dvc6200 double acting digital positioner without feedback\" decoding=\"async\" height=\"315\" loading=\"lazy\" sizes=\"(max-width: 356px) 100vw, 356px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-without-feedback-jpg.webp\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-without-feedback-jpg.webp 356w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-without-feedback-300x265.webp 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/DVC6200-Double-Acting-Digital-Positioner-without-feedback-64x57.webp 64w\" width=\"356\" \/><\/span><\/span>\n\n<figcaption>dvc6200 double acting digital positioner without feedback<\/span><\/span><\/figcaption>\n<\/figure>\n\n<h3 id=\"The_IP_Electrical_Converter—Transforms_Electrical_Signals_into_Pneumatic_Signals\">The I\/P Electrical Converter&mdash;Transforms Electrical Signals into Pneumatic Signals<\/span><\/span><\/h3>\n\nThe air supply passes through a constant throttle orifice (constant air resistance) to the nozzle. The drive signal from the electronic module controls the coil of the I\/P converter, attracting the armature to act. This movement of the armature moves the flapper closer to the nozzle, causing an increase in the back pressure at the nozzle. This increase translates to a higher pneumatic signal sent to the pneumatic amplifier, ultimately resulting in an increase in the output air pressure from the valve positioner. When the drive signal is reduced, the electromagnetic coil causes the armature\/flapper to move away from the nozzle, reducing its back pressure and, consequently, the output from the pneumatic amplifier decreases.<\/span><\/span><\/p>\n\n&nbsp;<\/p>\n\n<h2 id=\"How_to_Install_Fisher_Digital_Positioner_DVC6200_\">How to Install Fisher Digital Positioner DVC6200<\/span><\/span><\/h2>\n\n<h3 id=\"How_to_Install_and_Assembly_DVC6200_to_Sliding_StemLinear_Type_Control_Valves\">How to Install and Assembly DVC6200 to Sliding Stem\/Linear Type Control Valves<\/span><\/span><\/h3>\n\n<figure><img alt=\"Play: Video\" aria-label=\"Play: Video\" id=\"fallbackPlaceholder\" loading=\"lazy\" referrerpolicy=\"origin\" src=\"https:\/\/i.ytimg.com\/vi\/SBr99gejyII\/hqdefault.jpg\" \/><button aria-label=\"Play: Video\" id=\"playButton\"><\/button><\/span><\/span>\n\n<figcaption>Resource from&nbsp;Fisher Valves &amp; Instruments<\/strong><\/span><\/span><\/figcaption>\n<\/figure>\n\n<figure><img alt=\"mounting the dvc6200 digital valve controller1\" decoding=\"async\" height=\"335\" loading=\"lazy\" sizes=\"(max-width: 796px) 100vw, 796px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1.png\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1.png 796w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1-300x126.png 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1-768x323.png 768w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1-600x253.png 600w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller1-64x27.png 64w\" width=\"796\" \/><\/span><\/span><\/figure>\n\n<figure><img alt=\"mounting the dvc6200 digital valve controller2\" decoding=\"async\" height=\"321\" loading=\"lazy\" sizes=\"(max-width: 784px) 100vw, 784px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2.png\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2.png 784w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2-300x123.png 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2-768x314.png 768w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2-600x246.png 600w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller2-64x26.png 64w\" width=\"784\" \/><\/span><\/span><\/figure>\n\n<figure><img alt=\"mounting the dvc6200 digital valve controller3\" decoding=\"async\" height=\"339\" loading=\"lazy\" sizes=\"(max-width: 784px) 100vw, 784px\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3.png\" srcset=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3.png 784w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3-300x130.png 300w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3-768x332.png 768w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3-600x259.png 600w, https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2024\/03\/Mounting-the-DVC6200-Digital-Valve-Controller3-64x28.png 64w\" width=\"784\" \/><\/span><\/span><\/figure>\n\n<h3 id=\"How_to_Install_and_Assembly_DVC6200_to_Rotary_Type_Control_Valves\">How to Install and Assembly DVC6200 to Rotary Type Control Valves<\/span><\/span><\/h3>\n\n<figure><img alt=\"Play: Video\" aria-label=\"Play: Video\" id=\"fallbackPlaceholder\" loading=\"lazy\" referrerpolicy=\"origin\" src=\"https:\/\/i.ytimg.com\/vi\/bApJdlDl8To\/hqdefault.jpg\" \/><button aria-label=\"Play: Video\" id=\"playButton\"><\/button><\/span><\/span>\n\n<figcaption>Resource from&nbsp;Fisher Valves &amp; Instruments<\/strong><\/span><\/span><\/figcaption>\n<\/figure>\n\n<h2 id=\"How_use_375_or_475_Field_communicator_to_Calibrate_Fisher_DVC6200_Digital_Positioner\">How Use 375 Or 475 Field Communicator To Calibrate Fisher DVC6200 Digital Positioner<\/span><\/span><\/h2>\n\n<h3 id=\"Step_1_Initial_Connection\">Step 1.

This is a true digital control method, where piezo valves, similar to very small solenoid valves, are used to control loading and exhausting air, to and from the positioner. As such, the tuning parameters listed below are based upon this control method.<\/span><\/span><\/p>\n\nAdjustable Tuning Parameters Descriptions:<\/span><\/span><\/p>\n\n<ul>\n\t<li>[IMPUP] &amp; [IMPDN]: Impulse Length UP and DOWN<\/span><\/span><\/li>\n<\/ul>\n\n-These tuning parameters are similar to gain. They represent the minimum time the piezo valves will cycle; units are in milliseconds- ms. For example; if the value is 10 ms, the fastest the piezo valves will cycle is 10 ms, not any faster. Therefore, an increase in these values will increase the gain response. The range is 2.0 to 160 ms.<\/span><\/span><\/p>\n\n<ul>\n\t<li>[SSUP] &amp; [SSDN]: Short Step Zone<\/span><\/span><\/li>\n<\/ul>\n\nThese tuning parameters are similar to integral action. Essentially there are two actions of the piezo valves- long pulses and quick\/short pulses. The values are in percent of total stroke. When the position of the valve is within this Short Step Zone of the setpoint value, the positioner will begin the short pulses of the piezo valves. For example, if the current short step zone is 10 % and the positioner is given a step change from 0 to 50 %, the piezo valves are held wide open (long pulse) until the valve gets to within 10 % of the setpoint. Therefore, once the valve is at 40 %, the piezo valves will produce short\/quick pulses, to prevent overshoots. The smaller the value, the faster the response.<\/span><\/span><\/p>\n\n<ul>\n\t<li>[PRUP] &amp; [PRDN]: Prediction Up and Down<\/span><\/span><\/li>\n<\/ul>\n\n-These tuning parameters are similar to derivatives. This predicts the movement of the valve. The smaller the number, the less prediction is used, thus faster response. The range is 1 to 40.<\/span><\/span><\/p>\n\nHow to customize tuning parameters:<\/strong><\/span><\/span><\/p>\n\n<ul>\n\t<li>Enter Diagnostic Mode:<\/strong><\/span><\/span><\/li>\n<\/ul>\n\n-When the device is in Auto mode, press and hold all three buttons down at the same time:<img alt=\"button1\" decoding=\"async\" height=\"36\" loading=\"lazy\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2022\/06\/button1.jpg\" width=\"38\" \/><img alt=\"button2\" decoding=\"async\" height=\"32\" loading=\"lazy\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2022\/06\/button2.jpg\" width=\"35\" \/><img alt=\"button3\" decoding=\"async\" height=\"28\" loading=\"lazy\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2022\/06\/button3.jpg\" width=\"30\" \/>.<\/span><\/span><\/p>\n\n-Diagnostic name is shown in the lower right of the display.<\/span><\/span><\/p>\n\nEdit Tuning Value:<\/strong><\/span><\/span><\/p>\n\n-Go to the desired diagnostic parameter by pressing and releasing button.

For example, if the deadband value is 0.1 %, and the setpoint is 70 %, the PS2 will work the piezo valves to get within the following position range: 69.9 % to 70.1 %. Thus, the PS2 will continuously work to get within this deadband range. However, if the mechanics of the actuator and\/or valve cannot achieve this precise position, the PS2 will continuously hunt or oscillate around the setpoint position.<\/span><\/span><\/p>\n\nThere are two settings for the PS2 deadband: &ldquo;Auto&rdquo; or a fixed numerical value<\/span><\/span><\/p>\n\n<ul>\n\t<li>When configuration parameter &ldquo;DEBA&rdquo; = &ldquo;Auto&rdquo;, the deadband value is dynamic and changes per the process conditions. In other words, the deadband value changes if stiction or oscillation is detected. For example, the deadband value will increase when mechanical issues are detected. Additionally, the PS2 will periodically decrease the deadband value to try and achieve precise valve positioning. The deadband value changes in 0.1 % increments.<\/span><\/span><\/li>\n\t<li>Thus, only a fixed deadband value can be too small.<\/span><\/span><\/li>\n\t<li>Too small a deadband can cause valve oscillation and indicate.<\/span><\/span><\/li>\n<\/ul>\n\nChange Deadband Setting:<\/strong><\/span><\/span><\/p>\n\n<ul>\n\t<li>From AUT or MAN mode, press&nbsp;<img alt=\"button1\" decoding=\"async\" height=\"36\" loading=\"lazy\" src=\"https:\/\/cncontrolvalve.com\/wp-content\/uploads\/2022\/06\/button1.jpg\" width=\"38\" \/>button for 5 seconds.

For example, if the smallest movement that can be achieved is 0.8 %, then this is the best the valve assembly can move- in 0.8% increments. Therefore trying to achieve smaller movements is impossible and will result in oscillations.<\/span><\/span><\/li>\n\t<li>Oscillations can be reduced by setting the Deadband value to &ldquo;Auto&rdquo;<\/span><\/span><\/li>\n<\/ul>\n\n<h3 id=\"25_Supply_Air_Too_High\"> \n25 Supply Air Too High<\/span><\/span><\/h3>\n\n<h4>Symptoms<\/span><\/span><\/h4>\n\n<ul>\n\t<li>Oscillation\/hunting<\/span><\/span><\/li>\n\t<li>Valve action is too fast<\/span><\/span><\/li>\n<\/ul>\n\nMaximum air pressure ratings are indicated on the actuator&rsquo;s nameplate\/stamp.

The most common failure is a result of poor air quality, which can include moisture. In addition to an air drying system, it is recommended to install a coalescent filter on the supply line, directly upstream of the positioner. Siemens offers an Air Coalescing Filter, Model 2306, which removes dirt, oil, moisture, and other impurities from the instrument-air supply. \nIn addition, exceeding the recommended supply pressure will damage the valve block. The maximum pressure rating for the PS2 is: 101 psi (7 bar), see Supply Air Too High (Page 50). \nIt is recommended to install a regulator on the supply line, upstream from the positioner, and to regulate supply pressure so it does not exceed the maximum pressure rating of the PS2 and the actuator. Siemens offers a filter regulator, Model 91H, which regulates pressure and removes debris.<\/span><\/span><\/p>\n\nValve Block Testing<\/strong><\/span><\/span><\/p>\n\nThe following tests will refer to gauges on the supply and output(s) of pneumatic lines. If the PS2 does not have a gauge block, consider temporary gauge installation (inline) for diagnostic purposes.

In chemical production, process operators often describe that the control valve can&rsquo;t be closed and there is a large leakage, which affects the operation, we can use this function to meet the needs of the process as much as possible without replacing the control valve.<\/span><\/span><\/p>\n\n<h3 id=\"Case_2_The_flow_curve_of_the_control_valve_is_not_ideal\">Case 2: The flow curve of the control valve is not ideal<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nSIPART PS2 valve positioner parameter 12SFCT item, built-in six common&nbsp;<a data-id=\"https:\/\/cncontrolvalve.com\/why-do-different-control-valves-have-different-characteristics\/\" data-type=\"URL\" href=\"https:\/\/cncontrolvalve.com\/why-do-different-control-valves-have-different-characteristics\/\">flow characteristics<\/a>&nbsp;of control valves and user-defined flow characteristics, each control valve has its inherent flow characteristics, usually, this parameter of the positioner can follow the inherent flow characteristics of the control valve as long as it is set to Lin. If the flow characteristics of the control valve do not match the process requirements, the overall flow characteristics of the control valve can be changed through the setting of parameter 12SFCT. In short, the flexible setting of parameter 12SFCT can meet the process requirements according to the actual situation.<\/span><\/span><\/p>\n\n<h3 id=\"Case_3_Control_valve_action_direction_is_not_consistent_with_the_requirements\">Case 3: Control valve action direction is not consistent with the requirements<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nThis is related to the setting of the two parameters 7SDIR and 38YDIR of the valve positioner. The 7SDIR item is the direction set point, and the setting of the 7SDIR item determines the lifting and lowering of the actuator when the positioner receives the 4~20mA signal.<\/span><\/span><\/p>\n\nThe 38YDIR item is the travel direction display, which shows the lift of the actuator. By comparing with the actual switching direction of the control valve and the signal output from the control room, the parameter 7SDIR and parameter 38YDIR can be set correctly. when determining the switching direction of the control valve, it is necessary to cooperate with the process personnel, especially for the rotary type control valve, when the indication mark of the actuator is not clear, it is easy to misjudge the switching and cause production accidents, which must be taken seriously.<\/span><\/span><\/p>\n\n<h3 id=\"Case_4_Siemens_SIPARTPS2_positioner_initialization_stops_at_RUN5_and_does_not_reach_Finish_waiting_time_5min\">Case 4: Siemens SIPARTPS2 positioner initialization stops at RUN5 and does not reach Finish (waiting time &gt;5min)<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nThe cause of this fault is the installation of the positioner, actuator, and other components. You can check the installation of the positioner, actuator, and feedback part, correct the problem in time, re-assemble it and then initialize it to see if the initialization time can be shortened<\/span><\/span><\/p>\n\n<h3 id=\"Case_5_Siemens_SIPARTPS2_positioner_stops_at_RUN3_during_initialization\">Case 5: Siemens SIPARTPS2 positioner stops at RUN3 during initialization<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nThe reason for this fault is that the actuator takes too long to position. We observe whether the actuator switching time can be reduced by opening the restrictor completely or adjusting the pressure PZ (air pressure) to the high allowed value. You can also use a booster to increase the actuator force and shorten the switching time.<\/span><\/span><\/p>\n\n<h3 id=\"_Case_6_When_Siemens_SIPARTPS2_positioner_initializes_it_stops_at_RUN2_and_cannot_proceed_\">Case 6: When Siemens SIPARTPS2 positioner initializes, it stops at RUN2 and cannot proceed<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nDue to the high adaptive capability of the Siemens SIPARTPS2 positioner, it can work with linear and rotary type actuators with different travels. The positioner needs to set the parameters corresponding to the stroke during initialization so that the potentiometer detects the displacement of the actuator and the positioner drives the actuator action according to this displacement signal. If it stops at RUN2 during initialization, it is possible that the parameter setting is not reasonable. You can change the feedback shaft rotation angle in parameter 2YAGL of the valve positioner, changing 33&deg; to 90&deg;, and then initialize it again to see if it is successful. If the rotation angle of the feedback shaft is smaller than the small rotation angle, the initialization will not be successful. The feedback shaft rotation angle can be set as follows: set 33&deg; when the stroke of the linear actuator is less than 20mm. Set 90&deg; when the stroke of the linear actuator is more than 20mm. Set 90&deg; automatically for the rotary type control valve.<\/span><\/span><\/p>\n\nIn addition, the stroke or angle of the actuator can also be adjusted manually. Manually adjusting the actuator stroke to the start and end positions can complete the step of RUN2. It is not necessary to automatically find the starting point of the actuator during the initialization of the positioner. So when automatic initialization is not possible, manual initialization is selected to enable the control valve to be adjusted.<\/span><\/span><\/p>\n\n<h3 id=\"Case_7_The_positioner_makes_a_sound_of_puffing_and_the_control_valve_produces_a_vibration\">Case 7: The positioner makes a sound of puffing, and the control valve produces a vibration<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nThis is because of the positioner air tubing leakage, use soap water to detect the positioner outlet air pipeline and the connection of the actuator air source, find the leakage that the problem will be solved.<\/span><\/span><\/p>\n\n<h3 id=\"Case_8_Control_valve_maintenance_and_the_control_accuracy_has_problems\">Case 8: Control valve maintenance and the control accuracy has problems<\/span><\/span><\/h3>\n\n<h4>Solution:<\/span><\/span><\/h4>\n\nAfter maintenance of the control valve, due to changes in the positioner, valve stem, and feedback part, it must be initialized before the positioner and actuator can match each other and drive the actuator to act as a required control signal. The automatic initialization process of the Siemens SIPART PS2 valve positioner consists of five steps, which you can follow step by step for each task.<\/span><\/span><\/p>\n\n<ul>\n\t<li>Step 1, Determine whether the valve positioner is positive or negative actions and the LCD shows RUN1.<\/span><\/span><\/li>\n\t<li>Step 2, determine the starting point and range of the valve positioner, the LCD will show RUN2.<\/span><\/span><\/li>\n\t<li>Step 3, Determine the positioning time of the actuator, the LCD will show RUN3.<\/span><\/span><\/li>\n\t<li>Step 4, determine the valve positioning increment value, the LCD shows RUN4.<\/span><\/span><\/li>\n\t<li>Step 5, optimize the dynamic response of the actuator, and the LCD will display RUN5.<\/span><\/span><\/li>\n<\/ul>\n\nAfter completing the above five steps, the LCD will display Finish to complete the automatic initialization process and the valve positioner can work normally<\/span><\/span><\/p>\n\n<h3 id=\"Case_9_PS2_Smart_positioner_didn’t_work\">Case 9: PS2 Smart positioner didn&rsquo;t work<\/span><\/span><\/h3>\n\nTrouble Description: Single-acting valve positioner with HART function is used with a&nbsp;<a data-id=\"https:\/\/cncontrolvalve.com\/product-category\/butterfly-valves\/\" data-type=\"URL\" href=\"https:\/\/cncontrolvalve.com\/product-category\/butterfly-valves\/\">butterfly valve<\/a>&nbsp;(rotary type), the field failure is shown as when the input current signal is 15mA, the valve suddenly opens.
