Proportional relief valves type AGMZO-AES

two stage, without integral pressure transducer, ISO 6264 size 10, 20 and 32

Table F035-20/E

AGMZO are poppet type proportional pres-

sure relief valves, pilot operated without

integral pressure transducer, which provide

pressure regulation proportional to electro-

nic reference signal.

They operate in association with electronic

drivers, see section

쪨

, which supply the

proportional valve with proper current to

align valve regulation to the reference signal

supplied to the electronic driver.

They are available in different executions:

• -A, without integral pressure transducer.

• -AE, -AES, as -A plus analogue (AE) or

digital (AES) integral electronics 쩻.

The piloting pressure to the poppet

햲

modulated by a proportional relief valve

type RZMO

햳

, see table F007.

The pilot relief valve

햴

with manual adjust-

ment is installed to limit the max pressure

value.

The integral electronics

햵

ensures factory

presetting, fine functionality plus valve-to-

valve interchangeability and simplified

wiring and installation.

The electronic main connector

햶

is fully

interchangeable for -AE and -AES

executions. Standard 7 pin connector is

used for power supply, analog input

reference and monitor signals.

12 pin connector is used option /Z (AES).

Following communication interfaces 햷

햸

햹

햺 are available for the -AES

execution:

• -PS, Serial communication interface

for configuration, monitoring and

firmware updating through Atos PC

software - always present also for -BC,

-BP and -EH options

• -BC, CANopen interface

• -BP, PROFIBUS-DP interface

• -EH, EtherCAT 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 with

insulation class H.

Mounting surface: ISO 6264 size 10, 20 and 32

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).

Signal description

SOLENOID POWER SUPPLY CONNECTOR

9 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 0÷+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:

9.1 Option /I

It provides the 4÷20 mA current reference signal instead of the standard 0÷+10 V

DC. Monitor output signal is still the standard 0÷+10VDC.

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 cur-

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

DC on the enable input signal.

9.3 Possible combined option: /IQ

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 0÷+10 VDC 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

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 inter-

face, 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.
