LIQZO-TE are 2-way proportional cartridge
valves, designed for mounting in manifold
blocks which provide proportional not
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 position transducer
햴
;
• -TE, -TES as -T plus analogue (TE) or
digital (TES) integral electronics
햶
.
The regulation is operated by means of a
poppet
햲
with double piloting area, sli-
ding into a sleeve
l
햳
and provided of inte-
gral LVDT position transducer 햴.
The poppet is controlled in closed loop by
means of a proportional directional valve
햵 type DHZO, see table F160.
The integral electronics
햶
ensures factory
presetting, fine functionality plus valve-to-
valve interchangeability and simplified
wiring and installation.
The electronic main connector
햸
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 option /Z.
Following communication interfaces 햷 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.
Typical applications: plastic injection and
blow moulding, foundry and steel plants.

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.
zero point displacement < 1% at ΔT = 40°C
LIQZO-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).

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:
6.1 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
6.2 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.
6.3 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 cur-
rent output stage is still active). To enable the driver supply a 24V
DC on the enable input signal.
6.4 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
.
6.5 Possible combined options: /FI and /IZ

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:
8.1 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.
8.2 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

SOFTWARE TOOLS
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.

and the frequency responses of the bode diagrams in sections 12.2, 12.4, 12.6, 12.8, have to be considered as
average values. For the valves with digital electronics the dynamics performances can be optimized by setting the internal software parameters.

For the valves with digital electronics, the regulation characteristic can be modified by setting the internal software parameters, see tab. G500.
