Instruction Manual D103176X012 Installation April 2014 Section 2 Installation2‐2‐ Installation Note The DVC2000 is not designed to correct for significant stem rotation on sliding-stem actuators. WARNING Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before mounting the DVC2000 digital valve controller: D Always wear protective clothing, gloves, and eyewear when performing any installation procedures to avoid personal injury or property damage.
Instruction Manual Installation D103176X012 April 2014 Figure 2‐1.
Instruction Manual Installation D103176X012 April 2014 The linear magnet arrays have a valid travel range indicated by arrows molded into the piece. This means that the hall sensor (on the back of the DVC2000 housing) has to remain within this range throughout the entire valve travel. See figure 2‐2. The linear magnet arrays are symmetrical. Either end may be up. Figure 2‐2.
Installation April 2014 Instruction Manual D103176X012 Sliding-Stem (Linear) Actuators 1. Isolate the control valve from the process line pressure and release pressure from both sides of the valve body. 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. 2. Attach the mounting bracket to the actuator. 3.

Mount the digital valve controller to the mounting bracket, using the mounting bolts. See figure 2‐6. 8. Check for clearance between the magnet assembly and the DVC2000 feedback slot.
Instruction Manual Installation D103176X012 April 2014 Mounting on GX Actuators The DVC2000 digital valve controller mounts directly on the GX actuator without the need for a mounting bracket. However, in applications where the process temperature exceeds 80_C (176_F), it may be necessary to apply an insulating gasket between the actuator yoke and the DVC2000, as shown in figure 2‐8, The heat conducted from the process line will transmit through the valve body and actuator and ultimately to the DVC2000.
Instruction Manual Installation D103176X012 April 2014 If the process and ambient temperatures exceed the limits indicated by zone 2, then the DVC2000 high temperature mounting kit can not be used. If temperatures exceed zone 2, you must use an extension bonnet or bracket mounted instrument. Identify the yoke side to mount the DVC2000 digital valve controller based on the actuator fail mode. Refer to the GX Control Valve and Actuator System instruction manual (D103175X012). 1.
Instruction Manual Installation D103176X012 April 2014 5. Tighten the fasteners and remove the alignment template. Continue on with the appropriate step 6 below. Note Use a flat end hex key to tighten the mounting assembly fasteners to a torque of 2.37 N•m (21 in•lbf) for 4 mm screws, and 5.08 N•m (45 in•lbf) for 5 mm screws. While tightening the fasteners using the hex key should be sufficient, blue (medium) thread locker may be used for additional security. For Air-to-Open GX Actuators 6.
Instruction Manual Installation D103176X012 April 2014 8. Check for clearance between the magnet assembly and the DVC2000 feedback slot. The magnet assembly should be positioned so that the index mark on the pole pieces (back of the positioner housing) is within the valid range on the magnet assembly throughout the range of travel. See figure 2‐2. 9. Install tubing between the actuator casing and the pneumatic positioner output connection that has the arrow pointing away from the opening.

Instruction Manual Principle of Operation D103176X012 April 2014 Appendix A Principle of OperationA‐1‐ DVC2000 Operation The DVC2000 digital valve controller uses a traditional 4-20 mA input signal and converts it into a pneumatic output pressure that is delivered to the control valve actuator. Accurate control of the position of the valve is enabled by valve stem position feedback. The way in which the DVC2000 accomplishes this is through a two-stage positioner design.
Principle of Operation April 2014 Instruction Manual D103176X012 D The I/P converter assembly is connected to supply pressure and converts the drive signal into a pressure signal. The I/P converter is the pre-amplifier stage in the two-stage positioner design. This component enables high static gain for responsiveness to small changes in the input signal. D The I/P output is sent to the pneumatic relay assembly.

Instruction Manual Glossary D103176X012 April 2014 Glossary Alert Point An adjustable value that, when exceeded, activates an alert. Algorithm A set of logical steps to solve a problem or accomplish a task. A computer program contains one or more algorithms. Alphanumeric Consisting of letters and numbers. Analog Input Units Units in which the analog input is displayed and maintained in the instrument.
Instruction Manual Glossary D103176X012 April 2014 Controller A device that operates automatically to regulate a controlled variable. Deviation Usually, the difference between set point and process variable. More generally, any departure from a desired or expected value or pattern. Current‐to‐Pressure (I/P) Converter An electronic component or device that converts a milliamp signal to a proportional pneumatic pressure output signal.
Instruction Manual Glossary D103176X012 Equal Percentage A valve flow characteristic where equal increments of valve stem travel produce equal percentage changes in existing flow. One of the input characteristics available for a FIELDVUE Instrument. See also, Linear and Quick Opening. Feedback Signal Indicates to the instrument the actual position of the valve. The travel sensor provides the feedback signal to the instrument printed wiring board assembly.
Instruction Manual Glossary D103176X012 April 2014 Instrument Protection Determines if commands from a HART device can calibrate and/or configure certain parameters in the instrument. There are two types of instrument protection: Configuration and Calibration: Prohibits changing protected setup parameters; prohibits calibration. None: Permits both configuration and calibration. The instrument is ”unprotected.
Instruction Manual Glossary D103176X012 Pressure Sensor A FIELDVUE instrument internal device that senses pneumatic pressure. DVC2000 digital valve controllers have one actuator pressure sensor. April 2014 Seat Load Force exerted on the valve seat, typically expressed in pounds force per lineal inch of port circumference. Seat load is determined by shutoff requirements. Primary Master Masters are communicating devices. A primary master is a communicating device permanently wired to a field instrument.
Instruction Manual Glossary D103176X012 April 2014 Travel Accumulator Alert Checks the difference between the Travel Accumulator value and the Travel Accumulator Alert Point. The Travel Accumulator Alert is active when the Travel Accumulator value exceeds the Travel Accumulator Alert Point. It clears after you reset the Travel Accumulator to a value less than the alert point. Travel Alert Low Point Value of the travel, in percent of ranged travel, which, when exceeded, sets the Travel Alert Lo alert.
Instruction Manual Glossary D103176X012 Travel Limit A setup parameter that defines the maximum allowable travel (in percent of ranged travel) for the valve. During operation, the travel target will not exceed this limit. There are two travel limits: high and low. Typically the travel limit low will be used to keep the valve from going completely closed. Travel Range Travel, in percent of calibrated travel, that corresponds to the input range.
