  • Page 4: Introduction

    Special Conditions for Safe Use The enclosure is made of aluminium and any impact or friction caused by external objects shall be avoided in the application. Rubbing of the window with dry fabrics shall be avoided when the positioner is used in an hazardous atmosphere in order to avoid potentially incendive static discharges.
  • Page 5 The base unit of the system is the pneumatic positioner, used in either single or double acting applications. P5 comes standard with built in dampers, a high gain spool valve assembly, gauge ports and an O-ring sealed housing. The housing utilizes a unique O-ring seal that can be adjusted to a sealed or drained position.

  • Page 6: Storage Instructions

    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. Electropneumatic positioners/feedback modules contain electronic components which can be damaged by exposure to water.

  • Page 7: Storage Seal (P5/Ep5)

    Dependent on the local temperature variations, humidity and dew points and time in storage condensation could occur and accumulate inside on the I/P Converter causing erratic opera- tion or failure due to water and corrosion. The potential for condensation damage is especially high in southern climates and aggravated if units are exposed to direct sunlight.

  • Page 8: Function

    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. The lower arm position is determined by the position of the cam which is secured to the spindle and connected to the actuator shaft thus providing the feedback from the actuator/ valve.

  • Page 9: Installation

    4. Installation Air requirements Maximum supply pressure is 1 MPa (150 psi). Supply air shall be clean, dry and free from oil, water, moisture, foreign parts and debris. The air shall be freeze-dried or similar to a dew point of at least 10°C (18°F) below lowest expected ambient temperature.

  • Page 10: Connections

    5. Connections Air connections are tapped for 1/4" G or NPT male connectors and are clearly marked. Gauge ports are for 1/8" G or NPT. We recommend use of Loctite® 577 or similar user preferred for sealing. Electrical connection on I/P unit accepts 1/2" NPT or PG 13,5 (M20) cable gland.

  • Page 12: Cam Adjustment

    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. To secure the cam, make sure that screw 1 is backed out from the locking nut 2 then finger tighten the locking nut and tighten screw 1.

  • Page 13: Calibration

    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.

  • Page 14: Indicator Adjustment

    8. Indicator adjustment P5/EP5: To adjust the indicator, take off front cover and pull the indicator upwards until it comes off the Allen screw. 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.

  • Page 15: Dampers

    10. Dampers (P5/EP5) The standard built in dampers 5 located on the connecting block prov-ide a simple means of adjusting the actuator travel speed. For maximum actuator travel speed dampers shall be adjusted to mini-mum damping posi- tion. (Fig). Double acting actuators – adjust only OUTLET damper, set SUPPLY damper in minimum damping position.

    12. How to mount the I/P Unit to the positioner unit (P5/EP5) Switch off supply air and disconnect input signal – port I. Loosen screws 3 and remove connection block 1, the gauge or plug from port Ip, the fitting from port I and existing gasket 4.

    13. Maintenance When upgrading electronically parts inside a PMV positioner approved for installation in Hazardous locations special procedures apply, permission from PMV is required prior to the start of work. Please contact your local PMV Sales office for information regarding proper procedures.

  • Page 19: Diaphragm

    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. Make sure the diaphragm is centered.

  • Page 20: Feedback Spring

    Feedback spring Once the front cover and indicator are remo- ved, 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 un- der the balance arm 2.

  • Page 21: Lower Arm

    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 22: O-Rings

    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. On Q (red) O-rings, use a non silicon based grease.
