The Series PME electronic pressure regulator is composed of:
•M12 5 pin connector (1): provides connection to power supply, command signal and to the
output digital signal (for more details refer to the paragraph “Installation and
Commissioning").
The analog version of the Series PME electronic pressure regulator is available with two
different command signal types:
•Analog Voltage: voltage command signal 0 - 10 V.
•Analog Current: current signal 4 - 20 mA.
The choice between the two models must be made when ordering the regulator.
The configuration of some features of the Series PME electronic pressure regulator is done
through the NFCamApp app.

7. Electrical/Pneumatic circuit
8. Product storage and transport
•Adopt all measures possible to avoid accidental damage to the product during transport, and
when available use the original packaging.
•Observe the specified storage temperature range of -20 ÷ 70 °C.
9. Installation and start-up
•During unpacking, take great care not to damage the product.
•Check whether there are any faults caused by product transport or storage.
•Separate all packaging material to enable the recovery or disposal in accordance with current
standards in the country of use.
•Where possible avoid the risk of repeated pressure surges on the circuit where the
component is installed.
•The components must be fixed correctly using, where possible, the specific anchors and
ensuring that the fixture remains efficient even when the actuator is repeatedly used at a
high frequency and in the presence of strong vibrations.
•Once the component is installed, ensure that all air ways are securely connected to the
respective couplings.
•If the power supply is turned off, residual pressure may remain on the secondary side of the
regulators. The manufacturer must provide for additional exhaust components.
Recommended pneumatic circuit
•Keep the protective cap of the M12 connector until the regulator is completely installed.

•PME1 series electronic regulator can be connected to DIN rails using the relative elements
PCF-E520 fitted on the rear of the body using two M4 threaded holes.
•The Series PME electronic regulator can be directly fixed to a support using the 2 through
holes with diameter 4mm present on the body (not available in the PME1 manifold version).
•The PME electronic regulator can be fixed to the wall with the optional bracket code PRE-ST:
1. Fix the bracket to the wall with suitable screws
2. Connect the fittings G1/4; G3/8 or NPTF according to the PRE regulator size
3. Connect the regulator to the bracket with the two M4 x 55 screws supplied
•Make sure that the bracket is completely resting on the wall
•Connection of Manifold regulators with related Kit PRE-M-Pin-1-2
1. Insert the pins (1) in the seats on the regulator body
2. Insert the O-ring seal (3) into the special seat on the side face of the body
3. Bring the two modules sideways up until contact
4. Tighten the four grub screws (2) until they are locked (Tightening torque: 2,5 ± 0,5 Nm)

•There are 2 additional pneumatic ports on the PME series electronic regulator:
oM5 to discharge the exhaust valve to the outside. It is important to keep this port
free and clean to ensure that air is discharged without obstructions that could limit
the flow. If necessary, remove the pre-assembled filter, connect a suitable coupling
and use a hose to convey discharged air to a suitable area.
oM5 for external servo-pilot supply. The regulator is supplied with a preassembled cap
for the versions with internal servo-pilot supply and with the fitting 6625 3-M5 for
the versions with external servo-pilot supply.
•In order to connect the regulator with MD series, use the PRE-1/4-C kit for regulator with
G1/4 pneumatic port or use the PRE-3/8-C kit for regulator with G3/8 pneumatic port.
•The board implements a protection against inversion of polarity on the power supply
voltage.
•The board is also fitted with a non-resettable 1A fuse to limit the maximum current
absorption of the servovalve. Use a power supply unit able to deliver a current of at least
0,5A (recommended 1.0A).
•If UL/CSA standard compliance is required, the unit shall be supplied by an isolated power
source which fulfils at least one of the following the requirements of:
- Limited-Energy Circuit in accordance with UL/CSA 61010-1/ UL/CSA 61010-2-201
- Limited Power Source (LPS) in accordance with UL/CSA 60950-1
- a Class 2 supply source which complies with the National Electrical Code (NEC), NFPA 70,
Clause 725.121 and Canadian Electrical Code (CEC), Part I, C22.1. (typical examples are a
Class 2 transformer or a Class 2 power sources in compliance with, UL 5085-3/ CSA-C22.2
No. 66.3 or UL 1310/CSA-C22.2 No. 223). In order to respect the UL/CSA 61010
requirements, install the regulator inside a box, not in external environment.
•The power supply voltage must be within the range of 24V±10%.
•The board implements a protection against overload of the reference signal.
•The M12 8 pin male connector has the following pinout

10.Digital output
The digital output (OUT signal, pin 5) is a 0-24V digital signal. Through the NFCamApp
application it is possible to set the logic of this output:
•Active –high level: if the output is activated, its value is brought to a high logic level.
•Active –low level: if the output is activated, its value is brought to a low logic level.
Furthermore, based on the electrical connection made by the user, the following
configurations can be obtained:
•PNP: in this configuration the output signal refers to GND (pin 4), therefore the PNP digital
input of the control system must be connected between pin 5 (Dout) and pin 4 (GND).
•NPN: in this configuration the output signal refers to + 24V (pin 1), therefore the NPN digital
input of the control system must be connected between pin 5 (Dout) and pin 1 (+ 24V)
The operating mode of the digital output depends on what code is ordered. There are three
different operating modes:
•Error: the digital output changes state if the Regulator detects an error.
•Switch pressure: with this operating mode it is possible to set two fixed pressure thresholds,
a lower one and a higher one. The digital output changes state if the regulated pressure is
outside the range delimited by the two thresholds set. This is a useful way to check whether
the regulated pressure lies within the preset pressure range.
•Window pressure: with this operating mode it is possible to set two thresholds, a lower one
and a higher one, which determine a pressure range with respect to the target pressure
value.
The digital output changes state if the regulated pressure is outside the instantaneous range
(depending on the value of the target pressure at that moment) delimited by the two
thresholds set.
This is a useful way to check whether the regulated pressure lies within the pre-established
precision range.
