Air preparation
The PMV ELECTRO-PNEUMATIC Positioner
can work with supply pressure up to 8 bar ( 120
Psi”). In order to obtain a satisfactory operation
and high reliability a lter (25 microns) should be
placed as close to the Positioner as possible.
For larger pressure variations of the supply air
(or the supply pressure is too high) a pressure
regulator should be mounted next to the lter in
order to eliminate the uctuations. The supply
air must be dry, clean and free from oil.
Installation
The PMV E/P Positioner is available with a large
selection of feed back spindle designs to simplify
the mounting on the actuator.
Ports C I and C2 are to be connected to the ac-
tuator.
Port S is to be connected to the air supply (max
8 bar or 120 psi3 which should be of instrument
quality (clean, dry and oil free). If your supply
pressure is too high and/or the supply pressure
changes from time to time you must use a pres-
sure regulator.
Port I is to be used for the electrical connection
gland. This connection is 1/2~ NPT or PG 13.5
(M- 20) internal thread.
Input signal: 4-20 mA; 0-20 mA
Input resistance: 240 Ohm±10%
Important notice
The PMV Positioner with the cover (33) and the side frame
(3) dismounted.
P-2000 Ex/P-2020 Ex should be connected to
intrinsically safe circuits only. See installation
dwg for further details.
