DPZO-A* are two stage proportional val-

ves without position transducer, which

provide both directional and non compen-

sated flow control according to the elec-

tronic reference signal.

They operate in association with electro-

nic drivers, see section

, which supply

the proportional valves with correct cur-

rent 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

햵

• -AEG, as A plus integral digital cycle

generator (see table G120).

The 4-way spool 햳 , sliding into a 5-

chambers body 햲, is piloted in open loop

by the proportional pressure reducing

valve

햴

type DHRZO.

The integral electronics

햵

ensures factory

presetting, fine functionality plus valve-to-

valve interchangeability and simplified

wiring and installation.

The electronic main connector n 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 AEG version

and for option /Z (AES).

Following communication interfaces

햶

are

available for the digital -AES and -AEG

executions:

• -PS, RS232 serial communication

interface. The valve reference signal is

provided with analogue commands via

the 7 (or 12) pins connector

햷

• -BC, CANopen interface (only for -AES)

• -BP, PROFIBUS DP interface (only for

-AES)

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 valves have anti-

vibration, antishock and weather-proof

features.

Surface mounting: ISO 4401 size 10, 16

and 25.

Max flow respectively up to 160 l/min, 340

l/min and 680 l/min with valve differential

pressure

p = 30 bar, see section

Max pressure: 350 bar.

HYDRAULIC OPTIONS

4.1 Option /B Solenoid (for valve configuration *5*) and integral electronics at side of port A.

4.2 Pilot and drain configuration -The pilot / drain configuration can be modified as shown in the table E080 section 12.

The valve’s standard configuration provides internal pilot and external drain. For different pilot / drain configuration select:

Option /E External pilot (through port X). Option /D Internal drain.

Option /G Pressure reducing valve with fixed setting (= 40 bar for DPZO-1 and -2; 100 bar for DPZO-3) installed between pilot valve and main body.

It is advisable for valves with internal pilot in case of system pressure higher than 200 bar. This option is standard for DPZO-L*-1.

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).

GENERAL NOTES

CONNECTIONS FOR -A EXECUTION

Signal description

SUPPLY

SOLENOID POWER SUPPLY CONNECTOR

8 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:

8.1 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.

8.2 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 cur-

rent output stage is still active). To enable the driver supply a 24V

DC on the enable input signal.

8.3 Possible combined options: /IQ

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.

앬

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).

9.1 ELECTRONIC CONNECTIONS - 7 PIN MAIN CONNECTORS

10 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.

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 4÷20 mA current reference signal instead of the standard ±10 V

DC. Monitor output signal is still the standard 0÷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 /Z

It provides on a 12 pin main connector the above standard features plus:

Logic power supply

Option /Z provides separate 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 a 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. 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

VDC

, normal working corresponds to 24

VDC (pin 11 referred to pin 2)

SOFTWARE TOOLS

Note: A minimum time of 270 to 340 ms have be considered between the driver energizing with the 24 VDC power supply and when the valve is ready

to operate. During this time the current to the valve coils is switched to zero.

The functional parameters of digital valves, as the bias, scale ramp and linearization of the regulation characteristic, can be easily set and optimized with the

Atos E-SW programming software, available in three different versions according to the driver’s communication interfacing: E-SW-PS (Serial), E-SW-BC

(CANopen) and E-SW-BP (PROFIBUS DP).

A proper connection is required between the PC and the electronic driver communication port: for a more detailed description of software interface, PC

requirements, adapters, cables and terminators, please see table G500.

Proportional valves with fieldbus communication interface (-BC and -BP) 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. For detailed

description of available fieldbus feature, see table G510.

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.
