USER INSTRUCTIONS PMV D3 Digital Positioner FCD PMENIM0001-06 A5 - 09/16 Installation Operation Maintenance

The Flowserve PMV D3 is a digital positioner designed primarily for controlling modulating control valves. The positioner can be used with single or double acting actuators with either rotary or linear movement. The PMV D3 can be equipped with modules for feedback, limit switches and pressure gauges. Pressure sensors can be installed in the pneumatic block to offer advanced diagnostics. The modules can be factory assembled before delivery or fitted later. The modules for feedback and limit switches can contain the following: Feedback 4-20 mA and one of the following functions: - Two...

Special Conditions for Safe Use The enclosure of PMV D3I (Intrinsically safe) is made of aluminum and any impact or friction caused by external objects should be avoided in the application. Spare parts for certified products for hazardous locations Flowserve will only supply spare parts for PMV Explosion Proof or Intrinsically Safe products to certified purchasers. In order to be allowed to purchase spare parts for IS and EX products the purchaser must be registered by a proper Notified Body and covered under PMV QAN. According to IEC 60079-19 section 4 - 4.4.3.2 modifications to the...

PMV D3 Digital Positioner FCD PMENIM0001-06 A5 09/16 General The PMV D3 positioner is a precision instrument. It is essential that it is handled and stored correctly. Always follow the instructions below! Note: As soon as the positioner is connected and started, internal air leakage will provide protection against corrosion and prevent the ingress of moisture. For this reason, the air supply pressure should always be kept on. Storage indoors Store the positioner in its original packaging. The storage environment must be clean, dry, and cool (15 to 26°C, 59 to 79°F). Storage outdoors or...

3. Design The PMV D3 positioner contains: • Electronic board with microprocessor, HART modem, Profibus, Foundation Fieldbus, display, etc. • Valve block • Positional feedback with potentiometer • Sealed compartment for electrical connections. A PC configurator is available free of charge on our webpage www.pmv.nu The only requirements are: D3 positioner must have HART communication and a HART modem for connection between PC and positioner. With the configurator, settings can be done and saved in the PC, then downloaded to the positioner. The push buttons and display are accessible...

PMV D3 Digital Positioner FCD PMENIM0001-06 A5 09/16 PMV D3 General purpose The PMV D3 digital positioner has an easy to use user interface with 5 pushbuttons and local graphic LCD display. Communication options include 4-20mA HART, Foundation Fieldbus and Profibus PA. All PMV D3 positioners are available with Feedback, Fail Freeze (Fail in last position and hold when power is lost), 270-degree rotation (for extended travel) and gauge block. PMV D3 Intrinsically safe The PMV D3 digital positioner is available in intrinsically safe version for installation in hazardous areas. The...

5. Function Signal converter and microprocessor Control signal 4 - 20 mA Potentiometer Internal pilot valve A A D Internal pilot valve D Pressure regulator Replacable Filter C- The control signal function and the feedback from the potentiometer position are converted to digital signals that are processed with a PID algorithm in the microprocessor. This provides control signals to the two piezo-valves. For single acting (spring return) actuators connect C+ to the actuator and plug port C-. Single acting versions have the air block plugged in one end as default. To convert from double to...

PMV D3 Digital Positioner FCD PMENIM0001-06 A5 09/16 Removal of cover General purpose / Intrinsically safe Remove cover by first loosening the screw 1 and then the two screws 2. To install cover, first tighten the screw 1, then the two screws 2. Tighten to 1,5 — 2 Nm. Explosion proof To remove covers, first unscrew securing screws, then unscrew covers. To install, screw covers on as far as possible. Mount the securing screws. Back off slightly on the large cover to be able to screw down the securing screw completely. Securing screws Tubing Use tubes with a minimum inner diameter of 0 6...

Note: If the positioner is installed in a hazardous environment, it must be of a type approved for this purpose. All versions of the PMV D3 positioner have an ISO F05 footprint, A. The holes are used to attach the PMV D3 to the mounting bracket B. Please contact PMV or your local distributor representative with actuator specifics for the proper mounting bracket and hardware. The spindle adapter C can be changed to suit the actuator in question. It is important that the positioner’s spindle and the lever arms, that transfer the actuator movements, are correctly mounted. Any tension between...

Single acting positioner, Direct function Actuator with closing spring When the control signal increases, the pressure C+ to the actuator is increased. The valve stem moves upward and rotates the positioner spindle counter-clockwise. When the control signal drops to zero, C+ is vented and the valve closes. Reverse function Actuator with opening spring When the control signal increases the pressure C+ to the actuator is increased. The valve stem moves downward and the positioner spindle rotates clockwise. When the control signal drops to zero, C+ is vented and the valve opens. Double acting...
