double power supply only for LES
Spool offset position 1% to 6% of total stroke with
electrical power supply OFF (central safety rest position)
Spool control position with
electrical power supply ON
and reference signal = 0
(zero overlap position)
In absence of electric power supply (+24 V
DC), the valve main spool is moved by
the springs force to the central safety rest position characterized by a small off-
set of about 1% to 6% of the total stroke in P-B / A-T configuration.
This is specifically designed to avoid that in case of accidental interruption of the
electrical power supply to the valve, the actuator moves towards an undefined
direction (due to the tolerances of the zero overlap spool), with potential risk of
damages or personnel injury.
Thanks to the central safety rest position the actuator movement is suddenly
stopped and it is recovered at very low speed towards the direction correspon-
ding to the P-B/ A-T connection.
The main spool moves to the closed loop control position (zero overlap) when the
pilot pressure is activated, the valve is fed with power supply +24 V
DC and refe-
rence input = 0V (or 12 mA for option /I) is applied to the driver.
DPZO-LEB, LES proportional valves are CE marked according to the applicable Directives (e.g. Immunity/Emission EMC Directive and Low
V
oltage Directive). Installation, wirings and start-up procedures must be performed according to the general prescriptions shown in table F003
a
nd in the installation notes supplied with relevant components. The electrical signals of the valve (e.g. monitor signals) must not be directly
used to activate safety functions, or components, as prescribed by the European standards (Safety requirements of fluid technology systems
a
nd components-hydraulics, EN-982).

ENERAL NOTES
T
o avoid overheating and possible damage of the electronic driver, the valves must be never energized without hydraulic supply to the
pilot stage. In case of prolonged pauses of the valve operation during the machine cycle, it is always advisable to disable the driver

FIELDBUS - only for LES
Fieldbus allows the direct communication of the proportional valve with machine control unit for digital reference signal, diagnostics and
settings of functional parameters. Analog reference signal remain available on the main connector for quick commissioning and maintenance.
For detailed information about fieldbus features and specification see tech table GS510.
S
* options add the closed loop control of pressure (SP) or force (SF and SL) to the basic functions of proportional directional valves flow
regulation. A dedicated algorithm alternates pressure (force) depending on the actual hydraulic system conditions.
A
n additional connector is available for transducers to be interfaced to the valve’s driver (1 pressure transducer for SP, 2 pressure transducers
for SF or 1 load cell for SL). Main 12 pin connector is the same as /Z option plus two analog signals specific for the pressure (force) control.
For detailed information and connector wiring of options SP, SF, SL see tech table GS212.
N
ote: for proportional valve with zero overlapped spool the alternated pressure control (SP) is possible only for specific installation conditions,

Pressure reducing valve with fixed setting, installed between pilot valve and

100 bar for DPZO-4(M), DPZO-6 and DPZO-8
It is advisable for valves with internal pilot in case of system pressure higher than

Pressure reducing valve is standard for DPZO-1, for other sizes add /G option.

ELECTRONIC OPTIONS

P

DC m
ust be appropriately stabilized or rectified and filtered; 2,5 A fuse time lag is required in series to each driver
p
ower supply. Apply at least a 10000 mF/40 V capacitance to single phase rectifiers or a 4700 mF/40 V capacitance to
three phase rectifiers
Reference input signal - analog differential input with ±10 V
DC nominal range (pin D, E), proportional to desired valve spool position
Monitor output signal - analog output signal proportional to the actual valve’s spool position with ±10V
D
C
nominal range
Note: a minimum booting time between 400 and 800 ms has be considered from the driver energizing with the 24 VDC power supply before the valve
h
as been ready to operate. During this time the current to the valve coils is switched to zero
.
12.1 Option /F
It provides a Fault output signal in place of the Monitor output signal, to indicate fault conditions of the driver (cable interruption of spool tran-
sducers or reference signal - for /I option): Fault presence corresponds to 0 V
DC, normal working corresponds to 24 VDC
12.2 Option /I
It provides 4 ÷ 20 mA current reference and monitor signals, instead of the standard ±10 V.
Input signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±10 V or ±20 mA.
It is normally used in case of long distance between the machine control unit and the valve or where the reference signal can be affected by
electrical noise; the valve functioning is disabled in case of reference signal cable breakage.
12.3 Option /Q
To enable the driver, supply 24 V
DC on pin C referred to pin B: Enable input signal allows to enable/disable the current supply to the solenoid,
without removing the electrical power supply to the driver; it is used to maintain active the communication and the other driver functions when
the valve has to be disabled. This condition does not comply with European Norms EN13849-1 (ex EN954-1).
12.4 Option /Z
It provides, on the 12 pin main connector, the following additional features:
Enable Input Signal
To enable the driver, supply 24 V
DC on pin 3 referred to pin 2: Enable input signal allows to enable/disable the current supply to the solenoid,
without removing the electrical power supply to the driver; it is used to maintain active the communication and the other driver functions when
the valve has to be disabled. This condition does not comply with European Norms EN13849-1 (ex EN954-1).
Fault Output Signal
Fault output signal indicates fault conditions of the driver (solenoid short circuits/not connected, reference signal cable broken for 4÷20mA
input, etc.). Fault presence corresponds to 0 V
DC, normal working corresponds to 24 VDC (pin 11 referred to pin 2): Fault status is not affected
by the Enable input signal
Power supply for driver’s logics and communication - only for LES
Separate power supply (pin 9,10) allow to cut solenoid power supply (pin 1,2) while maintaining active diagnostics, USB and fieldbus communication.
A safety fuse is required in series to each driver power supply: 500 mA fast fuse.
12.5 Options /C - only for SP, SF, SL
Option /C is available to connect pressure (force) transducers with 4 ÷ 20 mA current output signal, instead of the standard ±10 V.
Input signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±10 V or ±20 mA.

alve's functional parameters and configurations, can be easily set and optimized using
A
tos E-SW programming software connected via USB port to the digital driver. For
fieldbus versions, the software permits valve's parameterization through USB port also if
the driver is connected to the central machine unit via fieldbus.
The software is available in different versions according to the driver’s options:
E
-SW-BASIC support: NP (USB) PS (Serial) IR (Infrared)
E-SW-FIELDBUS support: BC (CANopen) BP (PROFIBUS DP) EH (EtherCAT)
EW (POWERLINK) EI (EtherNet/IP)
E-SW-*/PQ support: valves with SP, SF, SL alternated control (e.g. E-SW-BASIC/PQ)
