fisher y690 manualThe Y690A Series design is ideally suited to control gas supply to in-plant processing equipment. The sliding pusher post design prevents damage to internal parts if the downstream pressure exceeds the setpoint.This pressure overcomes the regulator setting (which is set by a spring). Through the action of the sliding pusher post assembly, lever, and valve stem the valve disk moves closer to the orifice and reduces gas flow. If demand downstream increases, pressure under the diaphragm decreases. Spring force pushes the pusher post assembly downward, the valve disk moves away from the orifice, and the gas flow. Normal installation is with the spring case barrel vertical above or below the diaphragm case. However, when using a Type Y690A or Y690AM regulator, for proper operation to achieve the published capacities, the spring case barrel should be installed pointed down. For actuator casing drainage of the. These constructions comply with the recommendations of all NACE International sour service standards.

To avoid personal injury or property damage, it is important to carefully read, understand, and follow all contents of this quick start guide, including all safety cautions and warnings. Refer to Hazardous Area Approvals and Special Instructions for “Safe Use” and Installations in Hazardous Locations, on page 43, for approval specific safe use information. If you have any questions about these instructions, contact your Emerson Process Management sales office before proceeding. WARNING Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before proceeding with any Installation procedures: D?http://chiakhoathanhcong.com/cktc/FCKUploadedFiles/fallout-1-manual-install.xmlAlways wear protective clothing, gloves, and eyewear to prevent personal injury or property damage. D?Do not remove the actuator from the valve while the valve is still pressurized. D?Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator cannot suddenly open or close the valve. D?Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure from both sides of the valve. D?Use lock?out procedures to be sure that the above measures stay in effect while you work on the equipment. D?Check with your process or safety engineer for any additional measures that must be taken to protect against process media. D?Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not applying force to the valve stem; this will allow for the safe removal of the stem connector. WARNING To avoid static discharge from the plastic cover when flammable gases or dust are present, do not rub or clean the cover with solvents. To do so could result in a spark that may cause the flammable gases or dust to explode, resulting in personal injury or property damage. Clean with a mild detergent and water only. 3 DVC6200 Digital Valve Controllers Quick Start Guide August 2015 D103556X012 SIS Step 1—Install the DVC6200 on the Valve Housing Variations The DVC6200 housing is available in two different configurations, depending on the actuator mounting method. Figure 1 shows the available configurations. Figure 1. Housing Variations HOUSING FOR FISHER GX ACTUATORS HOUSING FOR LINEAR AND ROTARY ACTUATORS AND 657 SIZE 30i - 70i INTEGRAL OUTPUT PRESSURE PORT W9704 SLOTS FOR MOUNTING BOLTS HOLE FOR MOUNTING BOLT ROTARY NAMUR, M6 W9703 LINEAR, M8 General Mounting Guidelines If ordered as part of a control valve assembly, the factory will mount the digital valve controller on the actuator and calibrate the instrument.https://labroclub.ru/blog/dsr-1600-manual If you purchased the digital valve controller separately, you will need a mounting kit. The following procedures are general guidelines. See the instructions that come with the mounting kit for detailed information on mounting the digital valve controller to a specific actuator model. CAUTION The magnet assembly material has been specifically chosen to provide a long?term stable magnetic field. However, as with any magnet, care must be taken when handling the magnet assembly. Another high powered magnet placed in close proximity (less than 25 mm) can cause permanent damage. Potential sources of damaging equipment include, but are not limited to: transformers, DC motors, stacking magnet assemblies. General Guidelines for use of High Power Magnets with Positioners Use of high power magnets in close proximity to any positioner which is operating a process should be avoided. However, they should not be brought in close proximity to the magnet assembly (located at the back of the instrument) during process operations. Normally, these calibrators would not be used while an instrument is controlling the process. High power magnets should be kept at least 15 cm (6 inches) from the DVC6200. Note D?The mounting instructions also apply to the DVC6215 remote mount feedback unit. D?As a general rule, do not use less than 60 of the magnet assembly travel range for full travel measurement. Performance will decrease as the assembly is increasingly subranged. D?The linear magnet assemblies have a valid travel range indicated by arrows molded into the piece. This means that the hall sensor (the center point of the channel on the back of the DVC6200 housing) has to remain within this range throughout the entire valve travel. The linear magnet assemblies are symmetrical. Either end may be up. D?The magnet assembly may be referred to as a magnetic array in user interface tools. D?Mounting the instrument vertically, with the vent at the bottom of the assembly, or horizontally, with the vent pointing down, is recommended to allow drainage of moisture that may be introduced via the instrument air supply. Shut off all pressure lines to the actuator, releasing all pressure from the actuator. Use lock?out procedures to be sure that the above measures stay in effect while you work on the equipment. Figure 2. Mounting Parts for Sliding?Stem Actuator with up to 210 mm (8.25 inches) Travel ACTUATOR FEEDBACK BRACKET AND MAGNET ASSEMBLY MOUNTING BRACKET DIGITAL VALVE CONTROLLER X0381-1 2. Attach the mounting bracket to the actuator. 3. Loosely attach the feedback pieces and magnet assembly to the valve stem connector. Do not tighten the fasteners because fine adjustment is required. CAUTION Do not install a magnet assembly that is shorter than the physical travel of the actuator. Loss of control will result from the magnet assembly moving outside the range of the index mark in the feedback slot of the DVC6200 housing. 4. Using the alignment template (supplied with the mounting kit), position the magnet assembly inside the retaining slot. 5. Align the magnet assembly as follows: D?For air?to?open actuators (e.g. Fisher 667) vertically align the magnet assembly so that the center line of the alignment template is lined up as close as possible with the upper extreme of the valid travel range on the magnet assembly. The magnet assembly should be positioned so that the index mark in the feedback slot of the DVC6200 housing is within the valid range on the magnet assembly throughout the range of travel. See figure 3. 6 DVC6200 Digital Valve Controllers Quick Start Guide August 2015 D103556X012 D?For air?to?close actuators (e.g. Fisher 657) vertically align the magnet assembly so that the center line of the alignment template is lined up as close as possible with the lower extreme of the valid travel range on the magnet assembly. The magnet assembly should be positioned so that the index mark in the feedback slot of the DVC6200 housing is within the valid range on the magnet assembly throughout the range of travel. See figure 4. Figure 3. Air?to?Open Magnet Assembly Alignment Figure 4.

With no input current to the DVC6200, OUTPUT A is at zero pressure and OUTPUT B is at full supply pressure when the relay is properly adjusted. Note To have the actuator stem extend from the cylinder with increasing input signal, connect OUTPUT A to the actuator cylinder connection farthest from the actuator stem. Connect OUTPUT B to the cylinder connection closest to the actuator stem. To have the actuator stem retract into the cylinder with increasing input signal, connect OUTPUT A to the actuator cylinder connection closest to the actuator stem. While use and regular maintenance of a filter that removes particles larger than 40 micrometers in diameter will suffice in most applications, further filtration down to 5 micrometer particle size is recommended. Condensation in the air supply should be minimized. Check with an Emerson Process Management field office and industry instrument air quality standards for use with corrosive air or if you are unsure about the amount of air filtration or filter maintenance. When using natural gas as the supply medium, or for explosion-proof applications, the following warnings also apply: D?Remove electrical power before removing the housing cap. Personal injury or property damage from fire or explosion may result if power is not disconnected before removing the cap. D?Remove electrical power before disconnecting any of the pneumatic connections. D?When disconnecting any of the pneumatic connections or any pressure retaining part, natural gas will seep from the unit and any connected equipment into the surrounding atmosphere. Personal injury or property damage may result from fire or explosion if natural gas is used as the supply medium and appropriate preventive measures are not taken. Preventive measures may include, but are not limited to, one or more of the following: ensuring adequate ventilation and the removal of any ignition sources. D?Ensure that all caps and covers are correctly installed before putting this unit back into service. Attach the filter regulator to the side of the digital valve controller. This is the standard method of mounting the filter regulator. No tubing is required. D?When using a casing mounted filter regulator, use a separate casing mounting bracket (typically provided with the filter regulator). Attach the mounting bracket to the filter regulator and then attach this assembly to the actuator casing. D?If the supply pressure is less than the maximum actuator and instrument pressure rating, a regulator is not required. However, a filter is always required. Attach the filter securely to the actuator or instrument. 20 Quick Start Guide DVC6200 Digital Valve Controllers August 2015 D103556X012 WARNING Personal injury or property damage can occur from cover failure due to overpressure. Ensure that the housing vent opening is open and free of debris to prevent pressure buildup under the cover. This unit vents the supply medium into the surrounding atmosphere. When installing this unit in a hazardous (classified) location remote venting of the unit may be required, depending upon the area classification, and as specified by the requirements of local, regional, and national codes, rules and regulations. In addition to remote venting of the unit, ensure that all caps and covers are correctly installed. Personal injury or property damage may result from fire or explosion if natural gas is used as the supply medium and appropriate preventive measures are not taken. Natural Gas Certified, Single Seal instruments can be identified by the natural gas approval label shown in figure 18. Read and follow all local, regional, and federal wiring requirements for natural gas installations. Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval. Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or explosion. To avoid personal injury resulting from electrical shock, do not exceed maximum input voltage specified on the product nameplate. If the input voltage specified differs, do not exceed the lowest specified maximum input voltage. Personal injury or property damage caused by fire or explosion may occur if this connection is attempted in a potentially explosive atmosphere or in an area that has been classified as hazardous. Confirm that area classification and atmosphere conditions permit the safe removal of the terminal box cover before proceeding. The valve may move in an unexpected direction when power is applied to the digital valve controller. The digital valve controller is normally powered over the bus from a power supply. Refer to the FOUNDATION fieldbus or PROFIBUS site planning guide, available from your Emerson Process Management sales office, for proper wire types, termination, length, grounding practices, etc. Note To avoid the valve going to an unknown position when power is applied, the unit digital valve controller is shipped from the factory with the transducer block mode Out of Service. Wire the digital valve controller as follows, refer to figure 19. 1. Remove the wiring terminal box cap. 2. Bring the field wiring into the terminal box. When applicable, install conduit using local and national electrical codes which apply to the application. 3. The instrument is not polarity sensitive. Connect one wire from the controller output to one of the LOOP screw terminals in the terminal box shown in figure 19. Connect a 14 AWG (2.08 mm2) ground strap between the digital valve controller and earth ground when flammable or hazardous gases are present. Refer to national and local codes and standards for grounding requirements. 24 DVC6200 Digital Valve Controllers Quick Start Guide August 2015 D103556X012 4. Make connections to the ground terminal(s) following national and local codes and plant standards. As shown in figure 19, two ground terminals are available for connecting a safety ground, earth ground, or drain wire. The safety ground terminal is electrically identical to the earth ground. 5. Replace and hand tighten the cover on the terminal box. 6. Write the valve tag number on the top and bottom of the paper commissioning tag, as shown in figure 20. Figure 20. Paper Commissioning Tag WRITE THE VALVE TAG NUMBER HERE 18B9406?G 7. Remove the lower half of the paper commissioning tag and deliver it to the control system configurator. With the piece of paper, the control system configurator will be able to easily change the Device ID placeholder to the actual valve tag number. Note Alternatively, the valve tag number can be entered at the factory when specified at the time of order entry. When the valve tag number is electronically stored on the DVC6200, the control system will display the valve tag number instead of the Device ID. As a result, step 6 and 7 will not be required. 8. For Remote Mount applications, proceed to page 30. Otherwise proceed to Step 4—Configure the Digital Valve Controller on page 33. 25 DVC6200 Digital Valve Controllers Quick Start Guide August 2015 D103556X012 SIS HART Devices Refer to the DVC6200 HW1 instruction manual, the DVC6200 HW2 instruction manual, or the DVC6200 SIS instruction manual, available at www.FIELDVUE.com or from your local Emerson Process Management sales office for additional information. The digital valve controller is normally powered by a control system output channel. Shielded cable will ensure proper operation in electrically noisy environments. Wire the digital valve controller as follows, refer to figure 21: 1. Remove the wiring terminal box cap. 2. Bring the field wiring into the terminal box. Connect the control system output channel negative (or return) wire to the LOOP - screw terminal in the terminal box. WARNING Personal injury or property damage, caused by fire or explosion, can result from the discharge of static electricity. Connect a 14 AWG (2.08 mm2) ground strap between the digital valve controller and earth ground when flammable or hazardous gases are present. Refer to national and local codes and standards for grounding requirements. 4. As shown in figure 21, two ground terminals are available for connecting a safety ground, earth ground, or drain wire. The safety ground is electrically identical to the earth ground. The HART filter is a passive device that is inserted in field wiring from the HART loop. For more information on the description and use of the HART filter, refer to the HF340 HART filter instruction manual (D102796X012). For DVC6200 SIS applications proceed to Special Instructions for Safety Instrumented Systems on page 35. Configuration of the output circuit requires the proper DIP switch electrical setting on the main electronics board (figure 22) and also must be enabled with a user interface tool. The position transmitter circuit operates independently from the digital valve controller. The trip point can be based on valve travel anywhere within the calibrated travel range, or based on a device alert. In order for the switch output to function, the digital valve controller must be powered. If power is lost, the switch will always go to the open state. The output circuit, whether operating as a transmitter or switch, is galvanically isolated from the position control loop circuit such that different ground references between the 2 circuits are allowed. For DVC6200 SIS applications proceed to Special Instructions for Safety Instrumented Systems on page 35. Otherwise, proceed to Step 4—Configure the Digital Valve Controller on page 33. 28 DVC6200 Digital Valve Controllers Quick Start Guide August 2015 D103556X012 Figure 23.
