3. Air requirements
4. Installation
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.

filter/regulator is recommended to be installed as close to P5/EP5 as
possible to ensure proper supply air quality.
Before making pneumatic connections to the positioner, it is recommended that
the supply air lines are opened up and allowed to vent for 2-3 minutes to clear any
debris from the line. It is further recommended that a large paper bag is used to
collect any oil or humidity that may be present in the line during this purging,
direct the air flow into the bag. Should exessive amounts of oil and/or humidity
be present at this stage, a review of the pneumatic system should be carried out
and the problem corrected.
Poor air quality is one of the major causes of premature failure of pneumatic
equipment.
P5 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.
Proper alignment of the positioner spindle to the actuator shaft is very
important since improper alignment can cause excessive wear and friction to
the positioner.
The spindle/positioner shaft assembly allows for quick and simple spindle
changes. To ensure the proper connection, the spindle 3 has a spring clip 2
that must be properly installed. A solid ”click" should be felt when assembling
the two pieces insuring that the two flats 1 are engaged into the positioner
shaft groove.
The spindle can be removed, by inserting two screwdrivers under the two
tapered surfaces of the spindle and bending carefully. When the spring clip
releases the spindle will eject.
