3 CERTIFICATIONS
In the following is resumed the valves marking according to the Atex Group I and Group II certification
3.3 EXAMPLE OF NAMEPLATE MARKING
Notified body and certificate number
Marking according to Atex Directive
On/off valves equipped with intrinsecally
safe solenoids certified according to
ATEX 94/9/CE, protection mode:
- Ex II 1 G, Ex ia IIC T6, IIB T6 or IIA T5
(surface plants with gas or vapours environment, category 1, zone 0, 1 and 2).
- Ex I M2 Ex ia I (solenoids group I for surface, tunnels or mining plants).
"Intrinsically safe" protection is based on the
principle of limiting the energy of electric
circuits in environments with presence of
hazardous atmospheres. For this reason the
valves must be supplied through specific
“safety barriers” which limitate the max current to the solenoid. Atos provides galvanically insulated barriers for single and double
solenoid valves, see section
to. The
"intrinsically safe" circuit is virtually unable to
produce electrical surges or thermic effects
able to cause explosion in hazardous environments also in presence of specific
break-down situations.

18 INTRINSICALLY SAFE BARRIERS
The electric supply to these solenoids must be done through electronic devices situated out of potentially flammable environment (i.e. in safe
zone), which limit the electric current to the intrinsically safe solenoid. These electronic devices are normally called “intrinsically safe barriers”
approved and certified according to the Ex ia protection mode. To select the proper intrinsically safe barriers following data must be considered:
1) Vmax and Imax of the solenoid as specified in section must not be exceeded also in fault conditions;
2) the resistance of the solenoid is 150 Ω and the current supplied by the barrier, in normal operation condition, must be over the min. limit
(65 mA) to ensure the valve correct operation (over 70 mA for max performances).
The barriers type Y-BXNE 412 are galvanically isolated electronic devices, developed according to the European Norms EN60079-0/06, EN6007911/07 and certified ATEX 94/9/CE, protection mode Ex ia IIC.
These barriers ensure the optimized functioning of the Atos valves up to the max operating limits specified in section.
The barriers Y-BXNE-412 are double channel type, suitable to operate valves with double or single solenoid.
Two single solenoid valves can be connected to the barrier (one to each channel) but they cannot be contemporary operated.

Notes:
1) X6 and X4 versions differ only for the coil power (see Input Power) - The certified temperature class T6, T4, T3 is related to the max ambient temperature, from which results
the max solenoid surface temperature allowed in the application (see section
3
). The reference ambient temperature is -40÷+40°C (standard, see the sixth column in the
above table), for higher ambient temperature (-40÷+70 °C) the temperature class has to be degraded (option /7).
2) Max pressure on T port = 110 bar
3) Optional electrohydraulic venting available on request.
4) Valves are provided by NBR seals, which allow min ambient temperature down to -40 °C (max oil viscosity = 380 cSt). The min ambient temperature fr valves with PE option
(FPM seals) is -20°C.

OPERATING LIMITS OF ON/OFF DIRECTIONAL CONTROLS (based on mineral oil ISO VG 46 at 50°C)
The diagram have been obtained with warm solenoids and power supply at lowest value (Vnom-10%). For DHAXS valves the curves
refer to application with symmetrical flow through the valve (i.e. P → A and B → T). In case of asymmetric flow the operating limits
must be reduced.

16 CABLE GLAND
Following codes have to be specified for spare cable glands:
SP-PAXS19/M = with threated connection M20x1,5 UNI-4535 (6H/6g).
This cable gland must be blocked with loctite or similar or
with a lock nut.
The valves must be connected to the power supply using the
terminal board inside the solenoid.
Stainless steel cable glands - available on request - are certified ATEX
according to EN60079-0 and EN60079-1.
The cable must be suitable for the working temperature as
specified in the “safety instructions” delivered with the first
supply of the products.
Additional equipotential grounding can be also performed by the
user on the external facility provided on the solenoid case.
Minimum section of external ground wire = 4 mm
2
.
Minimum section of internal ground wire = the same of supply wire.
In order to reach the terminal board inside the solenoid, the top
plate of the solenoid must be removed.
Solenoids are provided with threated connection for cable

Table E138-7/E
Auxiliary hand levers for direct operated on-off solenoid valves size 06, type
DHI, DHE, DHA and proportional valves size 06, type DHZO, DHZE, DHZA
and QVHZO.
This option allows to operate the valves
in absence of electrical power supply,
i.e. during commissioning, maintenance or in case of emergency.
It is available with two different configurations depending to the installation
requirements:
MV = lever positioned vertically (per-
pendicular to the valve axis)
MO = lever positioned horizontally
(parallel to the valve axis)
When the valve is electrically operated
the hand lever remains stopped in its
rest position
The hand lever execution does not
affect the performances of the original
valves.

The core of electrohydraulic controls is the proportional valve that
regulates a pressure P or a flow Q according to the reference input
signal (normally ±10 V
DC
) supplied by the machine CNC. Particularly the
proportional valve must be operated by an electronic driver (see tab.
G001) which regulates a proper electrical current supplied to the valve’s
solenoid according to the reference signal. The solenoid converts the
electrical current into a mechanical force acting the spool against a
return spring: rising of the current produces a corresponding increasing
in the output force and consequent compression of the return spring,
thus the movement of the spool. The proportional valves can be single
stage or piloted, with or without pressure/position transducer.
Proportional valves with transducer provide better regulation accuracy.
In pilot operated executions the proportional pilot valve regulates flow
and pressure acting on the main operated stage.
When electrical failure occurs, return springs restore the neutral position
according to valve configuration, to ensure a fail-safe operation, i.e. to
ensure that in case of absence of reference signal or, generally, in case of electric system breakdown, the system configuration does not
cause damages. Fail-safe can be realized directly by the proportional valve (fail-safe operation intrinsic in valve configuration) or it can be
realized by consequential operation of a group of valves.
Atos valves may be spool type or cartridge execution and can be grouped in three different functional families:
•pressure control valves: relief valves and reducing valves regulate the hydraulic system pressure proportionally to the reference input signal;
•4-way directional control valves: direct and modulate the flow to an actuator proportionally to the reference input signal. These valves can be
used in open or closed loop control system to determine the direction, speed and acceleration of actuators;
•flow control valves: 2 or 3-way, pressure compensated, to modulate the flow independently to the user loads.
4 PROPORTIONAL VALVES AND DRIVERS
Atos proportional valves are equipped with ZO and ZOR, efficient solenoids (30 W and 40 W) respectively designed for direct-acting valves of
ISO 4401 size 06 and 10 and they are assembled in different options as follows:
ZO(R)-A: without integral transducer, open loop;
ZO(R)-AE, AES: as ZO-A plus integral electronic driver, analog or digital;
ZO(R)-T, -L: with integral LVDT single/double position transducer, closed loop, featuring high static and dynamic performances;
ZO(R)-TE, -LE, -LES: as ZO-T, -L plus integral electronic driver, analog or digital
In the new generation of -AE, -TE, -LE valves, the electronic driver is integral to the proportional valves and it is factory preset to ensure fine
functionality plus valve-to-valve interchangeability and to simplify installation wiring and system set-up. Electronics are housed and resin
encapsulated in a metal box to IP67, ensuring antivibration, antishock and weather-proof features; coils are fully plastic encapsulated.

1 WHAT IS PROPORTIONAL ELECTROHYDRAULICS?
F001
Electrohydraulic proportional controls modulate hydraulic parameters according to the electronic reference signals.
They are the ideal interface between hydraulic and electronic systems and are used in open or in closed-loop controls, see section 쪩, to achieve the fast, smooth and accurate motions required by today’s modern machines and plants.
The electrohydraulic system is a section of the overall automation architecture unit where information, controls, alarms can be transmitted in a
“transparent” way to the centralized electronic control unit and viceversa also via standard fieldbus, see tab. F002 for “Basics for digital electrohydraulics”.
Proportional electrohydraulics provides the following advantages in comparison with the electromechanical systems; intrinsic overload protection, automatic force adaption, fast operating response, self lubrification of the system, simple stepless variation in speed, energy storage
capability, high power density, forces and torques, long service life and high reliability.
3 CONTROL LOOPS
Today industrial machines are multi-axis machines, more and more electrohydraulically controlled by proportional devices. The axis motion can
be operated in “open loop” or in “closed loop” control, depending to the accuracy level required in the application. In many applications the
motion cycles do not require extreme accuracy, so they are performed in open loop, while each time the application requires the positioning of an
actuator, a closed loop control must be provided.

Fig 2: Electrohydraulic axes: a basic block diagrams
OPEN LOOP MOTION CONTROL
CLOSED LOOP MOTION CONTROL
Axis control is provided through the supply of a reference input signal to the driver of
the proportional valve.
There is no feedback of the valve’s regulated hydraulic parameter.
The accuracy of the open loop controls is strictly dependent of the good quality of the
hydraulic system and particularly of the proportional valve and of the relevant driver.
Axis control is provided through the supply of an input reference signal to a closed loop axis controller which receive the feedback signal from the actuator transducer. The controller compares the two signals and the resulting error is then
processed to the proportional valve, in order to align its regulation to the PID control loop requirements.
The accuracy of the closed loop controls is much better respect to the open loop
ones and it is less influenced by the external environmental disturbances, thanks
to the presence of the feedback.
Anyway the best is the overall quality of the hydraulic system, the best is the
accuracy of the axis control.

2 COMMUNICATION INTERFACES
1 DIGITAL TECHNOLOGY FOR PROPORTIONAL VALVES
The communication interface is the channel trough which the valve receives commands
and/or setting parameters and it returns information to the fieldbus controller.
Atos digital proportional valves are available with 3 optional communication interfaces:
• basic -PS: standard RS232 interface, to be coupled to an user-friendly PC software
(E-SW-PS) optimized with grafic interface, for the management of all the functional
parameters, see tab. G500.
The main feature of this basic version is the full interchangeability with the
corresponding analog executions, in fact the reference and the monitor signals are
analog, whereas the serial interface allows to manage the diagnostics and to set the
best configuration of the valve for the application’s requirements.
This approach enables a gradual introduction of the advantages of digital technology,
without perturbing the whole application/machine’s structure.
• option -BP: Profibus-DP (Fluid Power Technology protocol).
The valves with option -BC and -BP can be connected to the fieldbus network and thus
digitally operated by the machine control unit.
The functional parameters can be set via fieldbus using the standard communication
protocol implemented by Atos, or alternatively using the PC graphic software E-SW-PS
with the relevant USB interface supplied with the software KIT (see fig. 2 and tab.
G500). For start-up or maintenance operations, the valves with -BC or -BP interfaces
can be operated with analogue signals via the 7 (or 12) pins power supply connector.
Modern world is driven by digital electronics: computers, automation systems, cars and
missiles, telecomunications and advanced network are all based on digital
technology… …thanks to its typical benefits in comparison with analog: fast and
powerful data processing, easy programmability, high immunity to electromagnetic
noise, process parameters and data storage.
In electrohydraulics, digital electronics gives important advantages:
• better performances of electrohydraulic components: hysteresis, response time,
linearity;
• numerical software setting of hydraulic parameters (scale, bias, ramp, compensation
of non-linearities) for full repeteability and easy data storage
• diagnostic (fault, monitor) and computer assisted maintenance of machines and
systems;
• direct interfacing to field-bus networks.
Atos, leader in pioneering proportional electrohydraulics, is active from years on digital
electrohydraulics including: simulation models of valves and systems, research and
testing of new DSP microcontrolles, R&D of new solutions.
New digital electrohydraulics with on board electronics enable new funcionalities within
the conventional control architectures and represent the foundamental premise to
realize new compact machines with high technological contents.
The digital electronics integrate several logic and control functions (distributed
intelligence) and make it feasible and inexpensive the introduction in the hydraulic
system of the most modern fieldbus communication networks.
Atos digital driver’s range replicate the analogue one:
• E-RI-AES for valves without transducer
• E-RI-TES/LES for valves with single/double LVDT transducer
• E-RI-TERS for valves with pressure transducer

The concept of distributed
intelligence is applied in its easiest
form to the drivers type E-RI-AEG,
see fig. 8 and tab. G120.
This controller self-manages open
loop “fast-slow” positioning cycles,
interfacing up to five inductive
proximity sensors.
For any of the cycle phases it is
possible to set speed and ramps.
This solution has been developped
for applications with repetitive
cycles. The complete cycle is
managed by the valve itself without
auxiliary axis controller.

Servoactuators integrate several control functions within the driver itself, thus realizing truly compact electrohydraulic motion units.
E-RI-TEZ drivers for servoactuators, see fig. 9, besides driving the valve on which they are integrated, also perform a position, speed
and/or force control on the actuator itself.
For the end user, the main advantages of this kind of servosystems are:
• the self management of the motion control, with no need of using external axis cards
• the reduced number of wirings, thanks to the direct connection of the electronics to the peripherial sensors.
The distributed intelligence permits to locally manage the “fast” signals required by high performances closed loop controls, avoiding to
unnecessarily overload the fieldbus
communication line.
Application of such servoactuator solutions
takes place for example:
• for closed loop speed/position and
pressure control of the injection phase in
plastic presses
• for speed and force control of the moulds
closing in plastic presses
• for parison control is blow moulding
machines
• for master/slave syncronism in wood
machines and bending presses.
DIGITAL SERVOACTUATORS

11/05
A large number of the functional parameters of the valve can be numerically set trough the
communication interface, as:
• the bias and scale (fig. 4)
• the ramps, corresponding to the transition time from 0% to 100% of the valve’s regulation (fig. 5)
• the linearization of the regulation curve, allows to modify the hydraulic regulation of any valve,
as linearizing the characteristic of pressure control valve or change from linear to progressive
the characteristic of a directional control valve (fig. 6).
Many other regulations are available like: customized configuration of the reference signal
(standard ± 10 V), internal static self generation of the reference signal, dither signal, PID
parameters for dynamic behaviour, alarm setting of the high/low limits of the electronics
temperature, etc.
3 DIGITAL SETTINGS AND DIAGNOSTICS
4 COMBINED P/Q CONTROLS FOR DIRECTIONAL VALVES AND PUMPS
Detailed diagnostics information can be checked through the communication interface. They allow a complete analysis of the component
state and of its eventual malfunctionings, as for example:
• real time monitoring of the reference signal, of the feedback signals and of the electronics temperature
• alarm in case one of the above parameters overcome the set limits
• alarm in case of interruption of the feedback cable

The high computing capability of Atos digital electrohydraulic and its great flexibility allow to realize
new functionalities:
• new drivers E-RI-TES with /SP and /ZP options perform the combined pressure and flow control
on directional control valves. A remote pressure transducer must be installed on the system
where is required the max pressure control and its feedback has to be interfaced to the valve. If
the real value of the pressure in the system (measured by the pressure transducer) remains
below the relevant reference signal, provided by the machine controller, then the digital driver
regulates in closed loop the valve’s spool position, according to the flow reference signal. When
the real pressure become close to the relevant reference signal, the driver automatically performs
the closed loop control of the pressure. This option allows to realize accurate dynamic pressure
profiles. A multiple set of PID parameters can be real time selected during the axis motion via onoff signal to the 12 poles connector (option /SP) or through the - BC or -BP interfaces (option /ZP),
to optimize the control performances in the different phases of the machine cycle.
• new drivers E-RI-PES for variable displacement axial piston pumps (see fig. 7), integrate the
digital combined pressure and flow control (see above) with an electronic max power limitation.
A multiple set of PID parameters can be real time selected during the axis motion via the 12 pin
connector (option /S) or through the -BC or -BP interfaces (option /Z), to optimize the P/Q control
performances.

The following notes give some general suggestions and cautions on the procedures to ensure the good operation of an electrohydraulic system, with
particular reference to the closed-loop circuits, typical of modern electrohydraulic axes and of high-performances proportional components with integral
analog and digital electronics. For more detailed information about specific components see the relevant technical tables. For proper operation of electrohydraulic components, following prescription must be respected.

1.1 Power packs tank and tubes cleaning
Power unit tank has to be accurately cleaned, removing all the contaminants and any
extraneous object; piping has to be cold
bended, burred and pickled. When completely assembled an accurate washing of the
piping (flushing) is requested to eliminate the
contaminants; during this operation the proportional valves have to be removed and
replaced with by-pass connections, or on-off
valves.
1.2 Hydraulic connections
The flexible hoses have to be armoured type
on pressure line between powerpack an
d
proportional
valve and on return line from
proportional valve. If their potential breackage may cause damages to any machine or
system or can cause injure to the operator, a
proper retenction (as the chain locking at
both the pipe-ends) or alternately a protecting carter must be provided.
The proportional valve must be installed as
close as possible to the actuator, to assure
the maximum stiffness of the circuit and so
the best dynamic performances.
1.3 Hydraulic fluid
Use only good quality fluids according to
DIN 51524..535, with high viscosity index.
The recommended viscosity is 15÷100
mm
2
/sec at 40°C. When fluid temperature
exceeds 60°C select viton seals for components; in any case the fluid temperature must
not exceed 80°C.
1.4 Fluid filtration
The fluids filtration prevent the wearing of the
hydraulic components caused by the contaminans present in the fluid.
Fluid contamination class must be in accordance to ISO 18/15 code by mounting in line
pressure filter at 10∝m value and β
10=75.
In line filters must be mounted, if possible,
immediately before proportional valve; the filtering element is high cracking pressure type
with clogging electrical indicator, without bypass valve.
The flushing (at least 15 min. long) has to be
performed at the system commissioning to
remove the contaminants from the whole circuit.
After this
operation
filtering elements and flushing accessories cannot be used again, if
clogged.
Following additional warnings to be considered:
- make sure that the filters are of correct size
to ensure efficiency;
- the main source of contamination of an
hydraulic system is the air exchanged with
the environment: proper air filte rs on the
power unit tank to be always provided;
- filter the fluid when filling the tank (new
fluid is contaminated) with filtration Group
GL-15 (table L150) or similar.
1.5 Hydraulic drains and return lines
The function of drains is essential in all
systems, because they define the minimum
pressure level.
They must be connected to the tank without
counter-pressures.
Drain connections is provided on tie rod side
of the servocylinder, see figure.
Return line from proportional valve to tank
has to be sized in order to avoid variable
counter pressure < 1 bar; for this reason it is
recommended to use multiple separated
return lines directly connected to tank.
1.6 Fluid conditioning
A high-performance system must be thermally conditioned to ensure a limited fluid temperature range (generically between 40 and
50°C) so that the fluid viscosity remains constant during operation.
The operating cycle should start after the
prescribed temperature has been reached.
1.7 Air bleeds
Air in the hydraulic circuits affects hydraulic
stiffness and it is a cause of malfunctioning.
Air bleeds are provided in the proportional
valves and servocylinders; air dump valves
must be
inserted
at possible air accumulation points of the hydraulic system.
Following additional warnings to be considered:
on starting the system all the bleeds must be
released to allow removal of air. In particular
for servocylinders be careful to bleed the
transducer chamber, which is done by releasing the dump valve at the rod end;
- for the piping untight the connections;
- the system must be bled on first start-up
or after maintenance;
- use a precharged check valve (e.g. to 4
bars) on the oil general return line to tank
to avoid emptying of the pipes following a
long out of service.
2.1 Power supply
The voltage values to be within the following
range (depending on the type of supply
devices):
nominal voltage: V = 24 V
DC
;
filtered and rectified voltage: Vrms=21÷33 V
(ripple max = 2Vpp);
The supply device must be sized in order to
generate the correct voltage when all utilities
require max current at same time; in general
50W max intake electrical power can be considered for each supplied valve.
Following additional notes to be considered,
see figure below:
- power supply from a battery: overvoltages
(typically greater than 34 Volts) damage
the electronic circuits; it is recommended
the use of suitable filters and voltage suppressors;
- rectified AC power supply: the average
value to be within the limit Vrms = 21
28
Volts, with a supply capacitor equal to
10000 µF for each 3A of current expected
when single-phase power supply; 4700 µF
when three-phase power supply.

2.2 Electrical wiring
The power cables (coils, electronic adjusters
or other loads) to be separated from the
control cables (references and feed-backs,
signal grounds) to avoid interferences.
The electrical cables of the electronic signals
must be shielded as indicated in section 쪫
with shield or cablebraid connected to the
ground (according to CEI 11-17).
Recommended cable cross section;
- Supply and earth: 0,75 mm
2
;
- Coils: 1mm
2
(Lmax = 20 m); 1,5 mm2(for
longer distance) of shielded type;
- Voltage reference and LVDT feedback:
0,25mm
2
(Lmax = 20m) of shielded type;
Note: current reference signals options must
be provided when greater lengths apply to
reference and feedback connections;
suitable electronic units and transducers or
voltage to current converters are available.
- Service signal: 0,25mm
2
(Lmax = 20 m) of
shielded type;
- Electronic transducers: 0,25mm
2
(Lmax =
20 m) of shielded type;
2.3 Suppression of interferences by
electrical noise
When starting the system, it is always advisable to check that feedbacks, references and
signal grounds are free from interferences
and electrical noise which can affect the
characteristics of the signals and generate
instability in the whole system.
Electrical noises are high non-stationary
oscillations both on amplitude and frequency
around the signal average value; they can be
suppressed by shielding and grounding the
signal cables, see section 쪫.
Most of electrical noises are due to external
magnetic fields generated by transformers,
electric motors, switchboards, etc.
2.4 Integral drivers service signals and
options
- Monitor signal (standard)
The output signal (0÷5V, ±10V) is available to monitor the current to the solenoid
(AE, AES) or the spool position of the
valve (TE, LE, TES, TERS). Both signals
can be connected to main control unit for
sequence operations and diagnostics.
Note: electrical monitor signals taken via
valve electronics must not be used to switch off the machine safety functions. This is
in accordance with the European regulations standard (Safety requirements fluid
Technology systems and components);
- Current reference signal (option /I)
It provides the 4÷20 mA current reference
signal and the current feedback signals
instead of the standard 0÷10V (± 10V). 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. In case of
breakage of the reference signal cable,
the valve functioning is disabled.
- Fault signal (option /F)
Safety option providing an output signal
which switches to zero in case of interruption of the transducer feedback cable. In
this condition the valve functioning is disabled.
- Enabling contact (option /Q)
Safety option providing the possibility to
enable or disable the valve functioning
without cutting the power supply.
- Fail safe conditions
In case of no feedback signal due to
shortcircuit or break in the transducer
cabling, an automatic inhibition of the control card operates and zero current is fed
to valves. At the same time a LED (inside
the housing for the integral electronics) is
signalling the emergency condition.
- Logic state signals for E-RI-TE and
E-RI-LE (option /S)
This function gives three output signal in
order to control in real time the valve’s
spool position to allow the diagnostic controls. The signal “Zero position” is “on”
(22V 20 mA) when the spool is in the central position, while the other two signals
(“Position S1” and “Position S2”) are
“on” when the spool is moving according
to the excitation of the S1 or S2 solenoid,
respectively. This safety signals can be
used to switch-off the machine safety
functions.
- Enable fault and monitor for E-RI-TE
and E-RI-LE (option /Z)
Option providing the same characteristics
of /F and /Q plus the monitor signal 0 ÷ 10
V (or ± 10 V) of the spool position.
- Double power supply enable and fault
for E-RI-TES, E-RI-TERS, E-RI-LES
(option /Z)
Safety option, specifically introduced for -BC
and -BP fieldbus interfaces, provides two
separated power supplies for the digital electronic circuits and for the solenoid power
supply stage. The Enable and Fault signals
are also available. The option /Z allows to
interrupt the valve functioning by cutting the
solenoid power supply (e.g. for emergency,
as provided by the European Norms EN954-1
for components with safety class 2), but keeping energized the digital electronic circuits,
thus avoiding fault conditions of the machine
fieldbus controller.
- P/Q control for E-RI-TES-PS and
E-RI-LES-PS (option /SP)
Option providing in addition to the standard valve functions, a closed loop control
of the max pressure regulated by the proportional valve in the system, thus realizing a P/Q regulation. A remote pressure
transducer must be installed on the
system and its feedback has to be interfaced to the valve. If the real value of the
pressure in the system remains below the
relevant reference signal, the driver regulates in closed loop the valve’s spool position, according to the flow reference
signal. When the real pressure become
close to the relevant reference signal, the
driver automatically performs the closed
loop control of the pressure. This option
permits to realize accurate dynamic pressure profiles. Up to 4 set of PID pressure
parameters can be real time selected
during the axis motion via on-off signals to
the main 12 poles connector to optimize
the control performances in the different
phases of the machine cycle.
- P/Q control for E-RI-TES-BC (-BP) and
E-RI-LES-BC (-BP) (option /ZP)
Integral digital P/Q controller providing the
same characteristics of option /SP plus
additional double power supply, enable
and fault. In this option the multiple set of
PID pressure parameters can be real time
selected during the axis motion through
the -BC or -BP interfaces.
- Current feedback signal for E-RI-PES
(option /C)
The pump electronics is set to receive
4÷20 mA feedback signal from the remote
pressure transducer, instead of the standard 0÷10 V.
- P/Q control for E-RI-PES-PS (option /S)
Option providing up to 4 set of PID pressure parameters can be real time selected
during the axis motion via on-off signals to
the 12 poles connector to optimize the
control performances in the different phases of the machine cycle.
- P/Q control for E-RI-PES-BC (-BP)
(option /Z)
Integral digital P/Q controller providing the
same characteristics of option /SP plus
additional double power supply, enable
and fault. In this option the multiple set of
PID pressure parameters can be real time
selected during the axis motion through
the -BC or -BP interfaces.
2.5 Electronic calibrations
The valves with integral electronics normally
don’t need any calbration by final customer
because these operations have been already
performed before delivery of component (the
valves with integral electronics are used
more and more for their easier servicing and
improved reliability).
However Bias adjustment is allowed, to permit the regulation between the input reference electrical zero and the spool center position (actuator in a steady position); a new
calibration can be executed with particular
hydraulic conditions (i.e. cylinder with high
differential ratio value and/or high ∆p pressure operations). When electronic regulators in
Eurocard or other format are installed in the
control unit, the setting procedures are
shown on related technical tables; consult
them carefully before proceeding with the
start-up. Personalised calibrations in case of
particular requirements can be carried out
with the collaboration of Atos technical dept.
2.6 Temperatures and environments
Always chek that the operating environment
is compatible with the data given in the product tables. If necessary provide conditioning of the electronic cabinet.
In particular the integral electronics cannot
be used when ambient temperature is higher
than +60°C or lower than -20°C (-20°C to
+50 °C for digital -TERS execution).

The connection of the command signal to the electronics is depending to the type of signal generated from the PLC or CNC.
The following figures show the typical connections in case of common zero or differential command situations.

The correct shielding of signal cables has to be provided to protect the electronics from electrical noise disturbances, which could affect the valve functioning.
Examples of correct shielding criteria are shown in the following fig. E and F.
The shield connections of fig. G and H must be avoided because they could generate ground loops which enhance the noise effect.

TROUBLE SHOOTING TABLES
6.1 Open loop applications
To evaluate the fault and to find the defective component within an electrohydraulic system it is necessary a good cooperation between electronic and
hydraulic engineers.
Besides a good knowledge of the technical tables for each component, for performing analysis of the system it is necessary to evaluate the hydraulic
scheme and the electric wiring diagram related to operation cycle.
There is no general recipe for succes in fault finding due to quite diverse nature of the electrohydraulic systems; however the following table provides a
useful start point.
Notes:
- Most problems are solved by the replacement of defective components on site. The defective components can be repaired by the manufacturer.

DHZO-A* and DKZOR-A* are proportional
valves, direct operated without position
transducer, which provide both directional
and non-compensated flow control
according to the electronic reference
signal.
They operate in association with electronic
drivers, see section
쪨
, which supply the
proportional valves with proper current to
align valve regulation to the reference
signal supplied to the electronic driver.
They are available in different executions:

Standard driver execution provides on the 7 pin main connector:
Power supply
- 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to the driver power supply.
Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers
Reference input signal
- analog differential input with ±10 VDC nominal range (pin D, E), proportional to desired coil current
Monitor output signal
- analog output signal proportional to the actual valve’s coil current (1V monitor = 1A coil current)
Following options are available to adapt standard execution to special application requirements:
9.1 Option /I
It provides the 4÷20 mA current reference signal instead of the standard ±10 V
DC. Monitor output signal is still the standard ±10 VDC
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.
9.2 Option /Q
It provides the possibility to enable or disable the valve functioning without cutting the power supply (the valve functioning is disabled but the driver current output stage is still active). To enable the driver supply a 24V
DC on the enable input signal.

11 DIGITAL INTEGRAL DRIVERS -AES - OPTIONS
Standard driver execution provides on the 7 pin main connector:
Power supply
- 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to each driver power supply
Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers.
Reference input signal
- analog differential input with ±10VDC nominal range (pin D,E), proportional to desired coil current (4÷20 mA with cable
break detection, ±10 mA, ±20 mA or 0÷20 mA software selectable)
Monitor output signal
- analog output signal proportional to the actual valve’s coil current (1V monitor = 1A coil current)
Following options are available to adapt standard execution to special application requirements:
11.1 Option /Q
To enable the driver, supply 24Vdc on pin C referred to pin B: when the enable signal is set to zero the valve status is software selectable, by factory
default the valve functioning is disabled (zero current to the solenoid) but the driver current output stage is still active. For the complete list of selectable
status, see tab. G115.
11.2 Option /Z
It provides, on the 12 pin main connector, the following additional features:
Logic power supply
Separated power supply for the solenoid (pin 1, 2) and for the digital electronic circuits (pin 9, 10).
Cutting solenoid power supply allows to interrupt the valve functioning but keeping energized the digital electronics thus avoiding fault conditions of the
machine fieldbus controller. This condition allows to realize safety systems in compliance with European Norms EN13849-1 (ex EN954-1).
Enable Input Signal
To enable the driver, supply 24Vdc on pin 3 referred to pin 2: when the enable signal is set to zero the valve status is software selectable, by factory
default the valve functioning is disabled (zero current to the solenoid) but the driver current output stage is still active. For the complete list of selectable
status, see tab. G115.
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
VDC
, normal working corresponds to 24
VDC (pin 11 referred to pin 2)
: Fault status is not affected by the Enable input signal
11.3 Option /W - only for valves coupled with pressure compensator type HC-011 or KC-011 (see tab. D150).
It provides, on the 12 pin main connector, the above option /Z features plus the hydraulic power limitation function.
The driver receives the flow reference signal by the analog external input INPUT+ and a pressure transducer remotely installed in the hydraulic system,
has to be connected to the driver’s analog input TR.
When the actual requested hydraulic power pxQ (TR x INPUT+) reaches the max power limit (p1xQ1), internally set by software, the driver automatically
reduces the flow regulation of the valve. The higher is the pressure feedback the lower is the valve’s regulated flow:
Flow regulation = Min

SOFTWARE TOOLS
The driver configuration and parameters can be easily set with the Atos E-SW programming software, available in four different versions according to the
driver’s communication execution: E-SW-PS (Serial), E-SW-BC (CANopen), E-SW-BP (PROFIBUS DP), E-SW-EH (EtherCAT). Programming software
E-SW-BC, E-SW-BP, E-SW-EH for BC, BP and -EH drivers, can be also used to modify the valve’s parameterization through the serial communication interface, without disconnecting the valve from the machine’s bus line.
For a more detailed description of software interface, PC requirements, adapters, cables and terminators, please refer to technical table G500.
Programming software, must be ordered separately:
E-SW-* (mandatory - first supply) = Dvd including E-SW-* software installer and operator manuals; it allows the registration to Atos digital service
E-SW-*-N (optional - next supplies) = as above but not allowing the registration to Atos digital service
On first supply of the E-SW-* software, it is required to apply for the registration in the Atos download area: www.download.atos.com.
Once the registration is completed, the password will be sent by email.
The software remains active for 10 days from the installation date and then it stops until the user inputs his password.
With the password you can also download, in your personal area, the latest releases of the Atos software, manuals, drivers and configuration files.

and it is controlled in closed
loop position by means of the LVDT
position transducer
The integral electronics ensures factory
presetting, fine functionality plus valve-tovalve interchangeability and simplified
wiring and installation.
The electronic main connector is fully
interchangeable for -TE and -TES
executions.
Standard 7 pin main connector is used for
power supply, analog input reference and
monitor signals.
12 pin connector is used for options /Z
and /S*.
The special /S* options add a closed loop
control of pressure (/SP) or force (/SF and
/SL) to the basic closed loop spool position one.
Following communication interfaces are
available for the digital -TES execution:
• -PS, Serial communication interface for
configuration, monitoring and firmware
updating through Atos PC software
• -BC, CANopen interface
• -BP, PROFIBUS DP interface
The valves with -BC and -BP interfaces
can be integrated into a fieldbus
communication network and thus digitally
operated by the machine control unit.
The coils are fully plastic encapsulated
(insulation class H) and the valves have
antivibration, antishock and weather-proof
features.

GENERAL NOTES
5
DHZO and DKZOR proportional valves are CE marked according to the applicable Directives (e.g. Immunity/Emission EMC Directive and Low Voltage Directive).
Installation, wirings and start-up procedures must be performed according to the general prescriptions shown in table F003 and 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, like to switch-ON/OFF the machine’s safety
components, as prescribed by the European standards (Safety requirements of fluid technology systems and components-hydraulics, EN-892).

7 ANALOG INTEGRAL DRIVERS -TE - OPTIONS
Standard driver execution provides on the 7 pin main connector:
Power supply
- 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to the driver power supply.
Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers
Reference input signal
Monitor output signal
- analog differential input with ±10 VDC nominal range (pin D,E), proportional to desired valve spool position
- analog output signal proportional to the actual valve’s spool position with ±10 VDC nominal range
Following options are available to adapt standard execution to special application requirements:
7.1 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 transducers or
reference signal - for /I option): Fault presence corresponds to 0 V
DC, normal working corresponds to 24 VDC.
7.2 Option /I
It provides the 4÷20 mA current reference and monitor signals instead of the standard ±10 V
DC
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.
7.3 Option /Q
It provides the possibility to enable or disable the valve functioning without cutting the power supply (the valve functioning is disabled but the driver current output stage is still active). To enable the driver supply a 24V
DC on the enable input signal.
7.4 Option /Z
This option includes /F and /Q features, plus the Monitor output signal.
When the driver is disabled (0
VDC on enable signal) Fault option is forced to 0 VDC.

Standard driver execution provides on the 7 pin main connector:
Power supply
- 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to each driver power supply
Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers.
Reference input signal
- analog differential input with ±10VDC 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 ±10VDC nominal range
Following options are available to adapt standard execution to special application requirements:
9.1 Option /I
It provides 4÷20 mA current reference and monitor signals instead of the standard ±10 V.
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.
9.2 Option /Z
It provides on the 12 pin main connector the following additional features:
Logic power supply
Separated power supply for the solenoid (pin 1, 2) and for the digital electronic circuits (pin 9, 10).
Cutting solenoid power supply allows to interrupt the valve functioning but keeping energized the digital electronics thus avoiding fault conditions of the
machine fieldbus controller. This condition allows to realize safety systems in compliance with European Norms EN13849-1 (ex EN954-1).
Enable Input Signal
To enable the driver, supply 24V
DC on pin 3 referred to pin 2: when the Enable signal is set to zero the valve functioning is disabled (zero current to the
solenoid) but the driver current output stage is still active.
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
VDC
, normal working corresponds to 24
VDC (pin 11 referred to pin 2)
: Fault status is not affected by the Enable input signal
9.3 Options /SP, /SF and /SL
These options add the closed loop control of pressure (/SP) or force (/SF and /SL) to the basic functions of proportional directional valves: a dedicated
software alternates pressure (force) and valve’s spool position controls depending on the actual hydraulic system conditions.
A dedicated connector is available for the additional transducers that are required 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: one for reference (pin 7) and one for
monitor (pin 8).
9.4 Options /C
Options /CSP, /CSF and /CSL are available to connect pressure (force) transducers with 4 ÷ 20mA current output signal.
9.5 Possible combined options: /ISP, /ISF, /ISL, /CSP, /CSF, /CSL, /CISP, /CISF, /CISL and /IZ

The driver configuration and parameters can be easily set with the Atos E-SW programming software, available in three different versions according to the
driver’s communication execution: E-SW-PS (Serial), E-SW-BC (CANopen) and E-SW-BP (PROFIBUS DP).
For a more detailed description of software interface, PC requirements, adapters, cables and terminators, please refer to technical table G500.
Programming software, must be ordered separately:
E-SW-* (mandatory - first supply) = Dvd including E-SW-* software installer and operator manuals; it allows the registration to Atos digital service
E-SW-*-N (optional - next supplies) = as above but not allowing the registration to Atos digital service
On first supply of the E-SW-* software, it is required to apply for the registration in the Atos download area: www.download.atos.com.
Once the registration is completed, the password will be sent by email.
The software remains active for 10 days from the installation date and then it stops until the user inputs his password.
With the password you can also download, in your personal area, the latest releases of the Atos software, manuals, drivers and configuration files.

DPZO-A* are two stage proportional valves without position transducer, which
provide both directional and non compensated flow control according to the electronic reference signal.
They operate in association with electronic drivers, see section
쪨
, which supply
the proportional valves with correct current signal to align valve regulation to the
reference signal supplied to the electronic
driver.
They are available in different executions:
• -A, without position transducer;
• -AE, -AES as -A plus analogue (AE) or
digital (AES) integral electronics
쩻
;
The 4-way spool , sliding into a 5chambers body , is piloted in open loop
by the proportional pressure reducing
valve
type DHRZO.
The integral electronics
ensures factory
presetting, fine functionality plus valve-tovalve interchangeability and simplified
wiring and installation.
The electronic main connector 쩼 is fully
interchangeable for -AE and -AES
executions.
Standard 7 pin main connector is used for
power supply, analog input reference and
monitor signals.
12 pin connector is used for options /Z, /W
(AES).
Following communication interfaces ,
are available for the digital -AES execution:
• standard -PS, Serial communication
interface for configuration, monitoring
and firmware updating through Atos PC
software - always present, also for -BC, BP and -EH options
• optional -BC, CANopen interface
•
optional -BP, PROFIBUS DP interface
•
-EH, EtherCAT interface
The valves with -BC, -BP and -EH
interfaces can be integrated into a fieldbus
communication network and thus digitally
operated by the machine control unit.
Surface mounting: ISO 4401

DPZO-A* proportional valves are CE marked according to the applicable Directives (e.g. Immunity/Emission EMC Directive and Low Voltage Directive).
Installation, wirings and start-up procedures must be performed according to the general prescriptions shown in table F003 and 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, like to switch-ON/OFF the machine’s safety
components, as prescribed by the European standards (Safety requirements of fluid technology systems and components-hydraulics, EN-982).

.
In case of long time shutdown of the hydraulic supply to the pilot valve, the driver has to be switched off to avoid
its overheating.
The flow regulated by the directional proportional valves is not pressure compensated, thus it is affected by
the load variations.To keep costant the regulated flow under different load conditions, modular pressure
compensators are available (see tab. D150).

10 ANALOG INTEGRAL DRIVERS -AE - OPTIONS
Standard driver execution provides on the 7 pin main connector:
Power supply
- 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to the driver power supply.
Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers
Reference input signal
- analog differential input with ±10 VDC nominal range (pin D,E), proportional to desired coil current.
Monitor output signal
- analog output signal proportional to the actual valve’s coil current (1V monitor = 1A coil current)
Following options are available to adapt standard execution to special application requirements:
10.1 Option /I
It provides the 4÷20 mA current reference signal instead of the standard ±10 V
DC. Monitor output signal is still the standard ±10 VDC.
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.
10.2 Option /Q
It provides the possibility to enable or disable the valve functioning without cutting the power supply (the valve functioning is disabled but the driver current output stage is still active). To enable the driver supply a 24VDC on the enable input signal.
10.3 Possible combined options: /IQ

12 DIGITAL INTEGRAL DRIVERS -AES - OPTIONS
Standard driver execution provides on the 7 pin main connector:
Power supply
- 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to each driver power supply
Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers.
Reference input signal
- analog differential input with ±10VDC nominal range (pin D,E), proportional to desired coil current (4÷20 mA with cable
break detection, ±10 mA, ±20 mA or 0÷20 mA software selectable)
Monitor output signal
- analog output signal proportional to the actual valve’s coil current (1V monitor = 1A coil current)
Following options are available to adapt standard execution to special application requirements:
12.1 Option /Q - To enable the driver, supply 24Vdc on pin C referred to pin B: when the enable signal is set to zero the valve status is software selectable, by factory default the valve functioning is disabled (zero current to the solenoid) but the driver current output stage is still active. For the complete list of selectable status, see tab. G115.
12.2 Option /Z - It provides, on the 12 pin main connector, the following additional features:
Logic power supply
Separated power supply for the solenoid (pin 1, 2) and for the digital electronic circuits (pin 9, 10).
Cutting solenoid power supply allows to interrupt the valve functioning but keeping energized the digital electronics thus avoiding fault conditions of the
machine fieldbus controller. This condition allows to realize safety systems in compliance with European Norms EN13849-1 (ex EN954-1).
Enable Input Signal
To enable the driver, supply 24Vdc on pin 3 referred to pin 2: when the enable signal is set to zero the valve status is software selectable, by factory default the
valve functioning is disabled (zero current to the solenoid) but the driver current output stage is still active. For the complete list of selectable status, see tab. G115.
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 VDC, normal working corresponds to 24VDC (pin 11 referred to pin 2): Fault status is not affected by the Enable input signal
12.3 Option /W - only for valves coupled with pressure compensator type HC-011 or KC-011 (see tab. D150).
It provides, on the 12 pin main connector, the above option /Z features plus the hydraulic power limitation function.
The driver receives the flow reference signal by the analog external input INPUT+ and a pressure transducer remotely installed in the hydraulic system,
has to be connected to the driver’s analog input TR.
When the actual requested hydraulic power pxQ (TR x INPUT+) reaches the max power limit (p1xQ1), internally set by software, the driver automatically
reduces the flow regulation of the valve. The higher is the pressure feedback the lower is the valve’s regulated flow:
Flow regulation = Min

For detailed information on hydraulic power limitation, see tab. G115
Single solenoid valves (*51) can be

Valve's functional parameters and configurations, can be easily set and optimized using Atos E-SW programming software connected to the digital driver.
E-SW software is available in different versions according to the driver’s communication interface: PS (Serial) E-SW-PS, BC (CANopen) E-SW-BC, BP
(PROFIBUS DP) and EH (EtherCAT). Proportional valves with fieldbus communication interface can be directly managed by the machine control unit; it is
required to implement in the machine control the standard communication as described in the user manuals supplied with the relevant programming
software.

DPZO-T* are two stage proportional valves with position transducer on the main
spool which provide both directional and
non compensated flow control according
to electronic reference signal.
They operate in association with electronic drivers, see section
쪨
, which supply
the proportional valves with proper current to align valve regulation to the reference signal supplied to the electronic
driver.
They are available in different executions:
• -T, with position transducers ;
• -TE, -TES as -T plus analog (TE) or
digital (TES) integral electronics .
The 4-way spool , sliding into a
5-chambers body , is piloted by a
proportional directional valve type
DHZO (see tab. F160) and it is controlled
in closed loop position by means of the
LVDT transducer .
The pressure reducing valve with fixed
setting ensures a costant piloting
pressure.
The integral electronics ensures
factory presetting, fine functionality
plus valve-to-valve interchangeability
and simplified wiring and installation.
The electronic main connector is fully
interchangeable for –TE and –TES
executions.
Standard 7 pin main connector is used
for power supply, analog input reference
and monitor signals.
12 pin connector is used for options /Z
and /S*.
The special /S* options add a closed
loop control of pressure (/SP) or force
(/SF and /SL) to the basic closed loop
spool position one.
Following communication interfaces
are available for the digital -TES
execution:
• -PS, Serial communication interface for
configuration, monitoring and firmware
updating through Atos PC software
•
-BC, CANopen interface
• -BP, PROFIBUS DP interface
The valves with -BC and -BP interfaces
can be integrated into a fieldbus
communication network and thus digitally
operated by the machine control unit.
The coils are fully plastic encapsulated
(insulation class H) and the valves have
antivibration, antishock and weather-proof
features.
Mounting surface: ISO 4401 sizes 10, 16,
25 and 32.
Max flow respectively up to 160 l/min, 430
l/min, 830 l/min and 1100 l/min with valve
differential pressure Δp = 30 bar, see
table 쪨.
Max pressure: 350 bar.

Standard driver execution provides on the 7 pin main connector:
Power supply
- 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to the driver power supply
Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers
Reference input signal
- analog differential input with ±10 VDC 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 ±10 VDC nominal range
Following options are available to adapt standard execution to special application requirements:
7.1 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
transducers or reference signal - for /I option): Fault presence corresponds to 0 V
DC, normal working corresponds to 24 VDC.
7.2 Option /I It provides the 4÷20 mA current reference and monitor signals instead of the standard ±10 V
DC
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.
7.3 Option /Q It provides the possibility to enable or disable the valve functioning without cutting the power supply (the valve functioning is disabled
but the driver current output stage is still active). To enable the driver supply a 24V
DC on the enable input signal.
7.4 Option /Z
This option includes /F and /Q features, plus the Monitor output signal.
When the driver is disabled (
0 VDC
on Enable signal) Fault output is forced to 0
VDC
.
7.5 Possible combined options: /FI and /IZ
7 ANALOG INTEGRAL DRIVERS -TE - OPTIONS
DPZO-T* proportional valves are CE marked according to the applicable Directives (e.g. Immunity/Emission EMC Directive and Low Voltage Directive).
Installation, wirings and start-up procedures must be performed according to the general prescriptions shown in table F003 and 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, like to switch-ON/OFF the machine’s safety
components, as prescribed by the European standards (Safety requirements of fluid technology systems and components-hydraulics, EN-982).

Standard driver execution provides on the 7 pin main connector:
Power supply
- 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to each driver power supply
Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers
Reference input signal
- analog differential input with ±10VDC 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 ±10VDC nominal range
Following options are available to adapt standard execution to application requirements:
9.1 Option /I
It provides 4÷20 mA current reference and monitor signals instead of the standard ±10 V.
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.
9.2 Option /Z
It provides, on the 12 pin main connector, the following additional features:
Logic power supply
Separated power supply for the solenoid (pin 1, 2) and for the digital electronic circuits (pin 9, 10).
Cutting solenoid power supply allows to interrupt the valve functioning but keeping energized the digital electronics thus avoiding fault conditions of the
machine fieldbus controller. This condition allows to realize safety systems in compliance with European Norms EN13849-1 (ex EN954-1).
Enable Input Signal
To enable the driver, supply 24V
DC on pin 3 referred to pin 2: when the Enable signal is set to zero the valve functioning is disabled (zero current to the
solenoid) but the driver current output stage is still active.
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
VDC
, normal working corresponds to 24
VDC (pin 11 referred to pin 2)
: Fault status is not affected by the Enable input signal
9.3 Options /SP, /SF and /SL
These options add the closed loop control of pressure (/SP) or force (/SF and /SL) to the basic functions of proportional directional valves: a dedicated
software alternates pressure (force) and valve’s spool position controls depending on the actual hydraulic system conditions.
A dedicated connector is available for the additional transducers that are required 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: one for reference (pin 7) and one for
monitor (pin 8).
For futher details please refer to the driver technical table G212.
9.4 Options /C
Options /CSP, /CSF and /CSL are available to connect pressure (force) transducers with 4 ÷ 20mA current output signal.

DLHZO and DLKZOR are high
performance servoproportional valves,
direct operated, with sleeve execution and
LVDT position transducer, which provide
both directional and non compensated
flow control according to the electronic
reference signal.
They operate in association with electronic
drivers, see section
쪨
, which supply the
proportional valves with proper current to
align valve regulation to the reference
signal supplied to the electronic driver.
They are available in different executions:
• -T, with integral position transducer 햶;
• -TE, -TES as -T plus analog (TE) or
digital (TES) integral electronics 햷.
The 4-way spool 햳 is sliding into a
precision - machined and hardened sleeve
햴 for maximum overlapping accuracy.
The sleeve 햴 is mechanically forced into a
5-chambers body 햲.
The spool is directly
operated by a proportional solenoids 햵 and
it is controlled in closed loop position by
means of the LVDT position transducer 햶
.
The integral electronics 햷 ensures factory
presetting, fine functionality plus valve-tovalve interchangeability and simplified
wiring and installation.
The electronic main connector 햹 is fully
interchangable for -TE and -TES
executions.
Standard 7 pin main connector is used for
power supply, analog input reference and
monitor signals.
12 pin connector is used for options /Z
and /S*.
The special /S* options add a closed loop
control of pressure (/SP) or force (/SF and
/SL) to the basic closed loop spool position one.
Following communication interfaces 쩾are
available for the digital -TES execution:
• -PS, Serial communication interface for
configuration, monitoring and firmware
updating through Atos PC software
• -BC, CANopen interface
• -BP, PROFIBUS DP interface
The valves with -BC and -BP interfaces
can be integrated into a fieldbus
communication network and thus digitally
operated by the machine control unit.
The coils are fully plastic encapsulated
(insulation class H) and the valves have
antivibration, antishock and weather-proof
features.
Mounting surface: ISO 4401 sizes 06 and 10.

DLHZO and DLKZOR servoproportional valves are CE marked according to the applicable Directives (e.g. Immunity/Emission EMC Directive and Low Voltage Directive).
Installation, wirings and start-up procedures must be performed according to the general prescriptions shown in table F003 and 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, like to switch-ON/OFF the machine’s safety
components, as prescribed by the European standards (Safety requirements of fluid technology systems and components-hydraulics, EN-982).

GENERAL NOTES
Standard driver execution provides on the 7 pin main connector:
Power supply
- 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to the driver power supply
Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers
Reference input signal
- analog differential input with ±10 VDC 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 ±10 VDC nominal range
Following options are available to adapt standard execution to special application requirements:
7.1 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 transducers or
reference signal - for /I option): Fault presence corresponds to 0 V
DC, normal working corresponds to 24 VDC.
7.2 Option /I
It provides the 4÷20 mA current reference and monitor signals instead of the standard ±10 VDC
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.
7.3 Option /Q
It provides the possibility to enable or disable the valve functioning without cutting the power supply (the valve functioning is disabled but the driver current output stage is still active). To enable the driver supply a 24VDC on the enable input signal.
7.4 Option /Z
This option includes /F and /Q features, plus the Monitor output signal.
When the driver is disabled (
0 VDC
on Enable signal) Fault output is forced to 0
VDC
.
7.5 Possible combined options: /FI and /IZ

The flow regulated by the directional proportional valves is not pressure compensated, thus it is affected by the load variations.To keep costant the regulated
flow under different load conditions, modular pressure compensators are available (see tab. D150).

Standard driver execution provides on the 7 pin main connector:
Power supply
- 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to each driver power supply
Apply at least a 10000 μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers
Reference input signal
- analog differential input with ±10VDC 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 ±10VDC nominal range
Following options are available to adapt standard execution to special application requirements:
9.1 Option /I
It provides 4÷20 mA current reference and monitor signals instead of the standard ±10 V.
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.
9.2 Option /Z
It provides, on the 12 pin main connector, the following additional features:
Logic power supply
Separated power supply for the solenoid (pin 1, 2) and for the digital electronic circuits (pin 9, 10).
Cutting solenoid power supply allows to interrupt the valve functioning but keeping energized the digital electronics thus avoiding fault conditions of the
machine fieldbus controller. This condition allows to realize safety systems in compliance with European Norms EN13849-1 (ex EN954-1).
Enable Input Signal
To enable the driver, supply 24V
DC on pin 3 referred to pin 2: when the Enable signal is set to zero the valve functioning is disabled (zero current to the
solenoid) but the driver current output stage is still active.
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
VDC
, normal working corresponds to 24
VDC (pin 11 referred to pin 2)
: Fault status is not affected by the Enable input signal
9.3 Options /SP, /SF and /SL
These options add the closed loop control of pressure (/SP) or force (/SF and /SL) to the basic functions of proportional directional valves: a dedicated
software alternates pressure (force) and valve’s spool position controls depending on the actual hydraulic system conditions.
A dedicated connector is available for the additional transducers that are required 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: one for reference (pin 7) and one for
monitor (pin 8).
For futher details please refer to the driver technical table G212.
9.4 Options /C
Options /CSP, /CSF and /CSL are available to connect pressure (force) transducers with 4 ÷ 20mA current output signal.

The driver configuration and parameters can be easily set with the Atos E-SW programming software, available in three different versions according to the
driver’s communication execution: E-SW-PS (Serial), E-SW-BC (CANopen) and E-SW-BP (PROFIBUS DP).
For a more detailed description of software interface, PC requirements, adapters, cables and terminators, please refer to technical table G500.
Programming software, must be ordered separately:
E-SW-* (mandatory - first supply) = Dvd including E-SW-* software installer and operator manuals; it allows the registration to Atos digital service
E-SW-*-N (optional - next supplies) = as above but not allowing the registration to Atos digital service
On first supply of the E-SW-* software, it is required to apply for the registration in the Atos download area: www.download.atos.com.
Once the registration is completed, the password will be sent by email.
The software remains active for 10 days from the installation date and then it stops until the user inputs his password.
With the password you can also download, in your personal area, the latest releases of the Atos software, manuals, drivers and configuration files.

T5 and T7 spool types are specific for fine
low flow control in the range from 0 to 60%
(T5) and 0 to 40% (T7) of max spool stroke.
The non linear characteristics of the spool is
compensated by the electronic driver, so the
final valve regulation is resulting linear
respect the reference signal (dotted line).
DT7 has the same characteristic of T7 but it
is specific for applications with cylinders with
area ratio 1:2
