Page 4: Introduction
Always check www.pmv.nu for latest edition of manual. 1. Introduction The P4 is a pneumatic valve positioner for double acting actuators, rotary or linear. It can also be used for single acting applications by simply plugging one of the outlet ports, C1 or C2. - Page 5 EP5 Electro Pneumatic Digital Positioner FCD PMENIM0006-00-A5 12/18 The base unit of the system is the pneumatic positioner, used in either single or double acting applications. P5 comes standard with a high gain spool valve assembly, gauge ports and an O-ring sealed housing.

Page 6: Storage Instructions
EP5 Electro Pneumatic Digital Positioner FCD PMENIM0006-00-A5 12/18 2. Storage instructions PMV Positioner and feedback module storage and handling procedures PMV Positioners and feedback modules are precision instruments which should be stored and handled accordingly to avoid problems or damage. Electro-pneumatic positioners/feedback modules contain electronic components which can be damaged by exposure to water. - Page 7 EP5 Electro Pneumatic Digital Positioner FCD PMENIM0006-00-A5 12/18 Storage Seal (P5/EP5) P5/EP5 is supplied with all enclosure entry points sealed. The seal is only a storage seal, not to be used as seal when P5/EP5 is in operation. If Storage Seal is removed or damaged, make sure all open enclosure entry points are proper resealed before further shipping or storage.

Page 8: Function
FCD PMENIM0006-00-A5 12/18 3. Function The P4 and P5/EP5 operates on a force balance principal. Force is originated by the signal pressure transmitted through a diaphragm on to the balance arm. The opposing force is achieved through the feedback spring and is proportional to the position of the lower arm. -
Page 9: Installation
Poor air quality is one of the major causes of premature failure of pneumatic equipment. Installation P4 and P5/EP5 mounts on to the actuator using either the ISO F05 holes 4 and a PMV ISO mounting kit or by using the optional mounting adaptor and screws 5 to mount P5 on to existing PMV mounting kits. -

EP5 Electro Pneumatic Digital Positioner FCD PMENIM0006-00-A5 12/18 6. Cam adjustment With the cover and indicator removed, loosen the screw 1 and turn the cam locking nut 2 counterclockwise until the cam loosens. Adjust the cam 3 as desired making sure that the ball bearing 4 always is riding on an active lobe on the cam. -
Page 13: Calibration
FCD PMENIM0006-00-A5 12/18 7. Calibration P4/P5/EP5 is when shipped from PMV pre-calibrated for 90 ±0,5 deg rotation, (can also be 30, 45 or 60 deg, see installed cam). For most applications the valve closed position is more critical than valve open position, most attention should be paid at valve closed position. Always start calibration procedure by applying 0 % input signal, then adjusting zero. -
Page 14: Indicator Adjustment
Before installing the indicator make sure that the Allen screw is tightened. Press the indicator on the screw and adjust it by rotating clockwise to desired position. P4: Loose screw, adjust indicator, tighten screw. 9. Front cover and indicator cover The front cover of P5 is secured to the pneumatic unit with four captured screws and sealed with an O-ring 1. -

EP5 Electro Pneumatic Digital Positioner FCD PMENIM0006-00-A5 12/18 Diaphragm If P5 is equipped with I/P unit (EP5), the I/P unit must be removed to access the diaphragm. When installing the diaphragm make sure to place one washer on each side of the diaphragm. Put some Loctite 577 on the thread, install the screw 3 and tighten. - Page 19 EP5 Electro Pneumatic Digital Positioner FCD PMENIM0006-00-A5 12/18 Feedback spring Once the front cover and indicator are removed, the feedback spring can be easily accessed. Hold the spring 1 from the top, pull down and out. When installing, hold the assembly at the top, guide the lower part to position on the zero screw, then press down until it fits easily under the balance arm 2.
- Page 20 EP5 Electro Pneumatic Digital Positioner FCD PMENIM0006-00-A5 12/18 Lower arm Once the front cover is removed, the lower arm can be easily accessed. Remove the indicator, feedback spring and the cam. Loosen screw 2 and remove twist stop 1. Remove screw 3, lower arm 4, rod 5 and spring 6. Check rod and lower arm for wear, replace if necessary.
- Page 21 EP5 Electro Pneumatic Digital Positioner FCD PMENIM0006-00-A5 12/18 O-rings With time and use, O-rings can become brittle. This can cause poor operation and even failure of the positioner. Always check O-rings when performing any work on the positioner and replace bad O-rings. A thin layer of silicon grease applied on the NBR (Black) O-rings prolongs their life.
