P3P-R Pressure Regulator

INSTALLATION AND ELECTRICAL
CONNECTIONS
INSTALLATION
Before connecting the regulator P3P-R,
pay attention to the following instructions:
- Connect the regulator as close as
possible to the apparatus which will be
regulated (resulting in higher precision and
shorter response times);
- Piping section of pressure supply should
be sufficiently large;
- Connect the air filter (25-50µ, Dew point 2
°C) upstream from the regulator, and a
lubrificator if necessary, downstream;
- It is recommended to mount the regulator
in a vertical position, electronic on top.
With a flat mounting plate or an angle
mounting plate (accessories), connect the
regulator to the pneumatic network.
Connect the pressure supply on the inlet
port P and the regulation circuit with the
outlet port A.
It is recommended to use a silencer in the
exhaust R of types P3P-RJ…...
ELECTRICAL CONNECTIONS
The P3P-R program offers two connection
possibilities:
- by means of a cable gland Pg 13.5 and
screw terminals on the printed circuit plate;
- by means of a DIN circular plug-in
connector with crimp contacts.
A wire section of 0.75 mm2 is
recommended for the 24 V = power supply,
a shielded cable for the control signal.
Power supply
Direct current 24V ±15%
(details see page 4).
Electrical connection diagrams
See page 2.
Ensure that both "supply" and "control"
groundings are not interconnected outside
the P3P-R as they are already connected
internally.

1.0. Pg 13.5 CABLE GLAND
CONNECTION
- To access the screw terminals, first
remove the plastic cover by unscrewing
both cross-head tapping screws.
- Pass the cable through the cable gland
Pg 13.5.
-
Connect the wires on the screw
terminals according to the electrical
diagram.
-
Put on the cover and fasten it with the
tapping screws. Screw in the first turn
of the thread by hand, then with a
screw-driver screw down with a torque
of 1 Nm.
- Position the cable and fasten it by the
cable gland screw.
- Set up the inlet pressure
(max. 12 bar).

2.0. CIRCULAR PLUG-IN CONNECTION
(for series P3P-R…….D)
- The electrical connection of the pressure
regulator is obtained by a 6-pole circular
plug-in connector with crimp contacts.
- It is not necessary to remove the cover.
The P3P-R is equipped with a mounted
plug-in connector.
- The contact positions are marked with (1)
to (6) on the pin socket (6 poles +
grounding).
- Crimp the pin-contacts and insert them in
the pin socket according to the electrical
diagrams.
- Position the cable, fasten it by the cable
gland and mount the plug on the regulator.
- Set up the inlet pressure (max.12 bar).

P3P-R SETTING INSTRUCTIONS
The P3P-R regulators are fully adjusted
and quality controlled at the factory to
obtain standard specifications.
Control signal:
0 to 10 Volt or 4 to 20 mA corresponding to
an output pressure range of 0.2 to 10 bar
(1 V resp. 5.6 mA corresponds
to 1 bar).
Hysteresis:
~ 100 mbar. This value is adjusted in order
to obtain an inaudible correction of the two
2-way solenoid pilots when there is no
change of the control signal.
Setting corrections:
In case where the original calibration would
not fully correspond to the required setting
(e.g.: variation due to the temperature), a
correction may be made by the user. To
access the base circuit plate and its
potentiometers, first remove the plastic
cover.
Base printed board assembly:
P1 = Calibration of control signal
0 - 10 V / 4 - 20 mA
P2 = Zero pressure offset
P3 = Hysteresis
Setting up all other sealed potentiometers
is strictly forbidden. Any action on the
sealed potentiometers would be subject to
a loss of warranty. Parker Pneumatic
reserves all rights to modify the position of
the potentiometers on the electronic
packages.
Output signal module:
P6 = 0utput signal 0 - 10 V
(correction of amplitude)
P7 = 0ffset correction 0 - 10 V
P8 = 0ffset shifting correction
for 4 - 20 mA
P9 = Alarm setting up 0/24 V
The setting of the output signal module is
only possible within certain limits.
Attention: Take care to set up only the
indicated potentiometers on page 3,
according to instructions. For carrying out
the set up, it is necessary to have a
Voltage and/or Current Multimeter as well
as a precision manometer or a pressure
sensor with digital display. The P3P-R.
should be pressurized and energized
except when setting up the alarm.
