2. Introduction
This manual illustrates how to properly use the Series PRE electronic pressure regulator in its
version with analog inputs and with digital inputs (preset).
This version of the Controller is identified with code 0118 xx xx xxx x xxxxx, where 0118 indicates
the analog version and is followed by year, week, machine, station and serial number.
For more information, refer to the manual dedicated to the Camozzi UVIX supervision software
(Universal Visual Interface X).
3. General recommendations
The recommendations regarding safe use in this document should be observed at all times.
• Some hazards can only be associated with the product after it has been installed on the
machine/equipment. It is the task of the final user to identify these hazards and reduced the
associated risks accordingly.
• The products dealt with in this manual may be used in circuits that must comply with the
standard EN ISO 13849-1.
• For information regarding component reliability, contact Camozzi.
• Before proceeding with use of the product, carefully read all information in this document.
• The instructions in this manual must be observed together with the instructions and
additional information regarding the product in this manual, available from the following
reference links:
o web site http://www.camozzi.com
o Camozzi general catalogue
o Technical assistance service
• Assembly and start-up operations must be performed exclusively by qualified and authorized
personnel on the basis of these instructions.
• It is the responsibility of the system/machine designer to ensure the correct selection of the
most suitable pneumatic component according to the intended application.
• For all situations not contemplated in this manual and in situations in which there is the risk
of potential damage to objects, or injury to persons or animals, contact Camozzi for advice.
• Never make unauthorized modifications to the product. In this case, any damage or injury
to objects, persons or animals will be the responsibility of the user.
• All relevant product safety standards must be observed at all times.
• Never intervene on the machine/system before verifying that all working conditions are safe.
• Before installation and maintenance, ensure that the specific envisaged safety locks are
active, and then disconnect the electrical mains (if necessary) and system pressure supply,
discharging all residual compressed air from the circuit and deactivating residual energy
stored in springs, condensers, recipients and gravity.

• To reduce the noise levels caused by the discharge of air from the component, envisage the
use of silencers or convey the fluid to a zone where no personnel are envisaged during
normal operation.
• Avoid covering the equipment with paint or other substances that may reduce heat
dissipation.
• Avoid cleaning with aggressive agents such as to dull the plastics and make it difficult to
read the screen
• In the event of an electrical power failure and pneumatic supply at the port connection 1,
the regulated pressure on port connection 2 will not be maintained and can be
discharged.
4. Product description:
The Series PRE electronic pressure regulator is composed of:
• M12 8 pin connector (6): provides connection to power supply, command signal, feedback
signals and to the output signal (for more details refer to the paragraph “Installation and
Commissioning").
• LCD display (1): if present (depends on the code), it shows the measurement of the
regulated pressure and allows to configure some parameters.
• General diagnostic LED bar (3): provides a quick indication of the general status of the
device (for more details, refer to the "Use" paragraph).
• Function keys (2): if the LCD display is present (depends on the code), these keys allow to
access and navigate the Regulator menu (for more details, refer to the "Use" paragraph).
• Micro USB connector (5) and wireless communication LED (4) to connect to the UVIX: the
device can be connected to the UVIX supervision software via wireless (if present) or USB
that allows to configure and monitor the device.

The analog version of the Series PRE 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 PRE electronic pressure regulator is done
through the UVIX supervision software.
Two operating modes have been implemented:
• Automatic: the pressure target is set via the analog input. At startup the Regulator is in this
mode.
• Manual: the pressure target is set using the function keys or through a special command of
the UVIX supervision software. The regulator must be set in this mode during the
configuration phase in order to avoid unwanted pressure adjustments.
