They are specifically designed to achieve high speed closed loop controls; the cartridge execution for blocks installation grants high flow capabilities and minimized pressure drops. The main poppet is controlled in double closed loop position by the DLHZO (DLKZOR for size 63 to 00) servoproportional valve (see table F80) and LVDT position transducers and. The electronic driver supplies the servoproportional valve with proper current to align valve regulation to the reference signal, the integral execution has rugged construction and grants factory presetting for valve-to-valve interchangeability Mounting surface: ISO 7368 LIQZO: sizes from 6 to 40, Max pressure 350 bar Max flow: 600 to 2500 l/min LIQZP: sizes from 50 to 00, Max pressure = 420 bar Max flow: 4000 to l/min - LES - NP L4 / * ** / * Flow control valve LIQZO = size 6 to 40, Pmax 350 bar LIQZP = size 50 to 00, Pmax 420 bar L = without integral electronics LE = with integral analog electronics LES = with integral digital electronics Fieldbus interfaces for LES: USB port always present NP= Not present BP = PROFIBUS DP BC= CNopen EH = EtherCT Valve size, see section LIQZO = l/min LIQZP = l/min Nominal flow (l/min) at Δp 5 bar Series number Seals materials see section, - = NBR PE = FPM BT = HNBR (only -LES) Electronic options, see section 8, 0 : F = fault signal I = current reference input and monitor (4 20 m) Q= enable signal Z = for LE execution enable, fault and monitor signal (2 pin connector) for LES execution double power supply, enable, fault and monitor signal (2 pin connector) Configuration: 2 = 2 way Spool type - regulating characteristics: L4 = linear LIQZO-L LIQZO-LE LIQZO-LES F330

2 2 GENERL NOTES LIQZO-L* proportional cartridges 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). WRNING To avoid overheating and possible damage of the electronic driver, the valves must be never energized without hydraulic supply to the pilot stage. In case of prolonged pauses of the valve operation during the machine cycle, it is always advisable to disable the driver (for -LE and -LES valves with option /Q or /Z). safety fuse 2,5 installed on 24VDC power supply of each valve is always recommended for valves -LE and -LES, see also Power supply note at sections 8 and 0 3 MIN CHRCTERISTICS ssembly position ny position Subplate surface finishing Roughness index, Ra 0,4 flatness ratio 0,0/00 (ISO 0) MTTFd valves according to EN ISO years, see technical table P007 -L execution = -20 C +70 C mbient temperature range -LE and -LES executions = -20 C +60 C /BT option only for -LES executions = -40 C +60 C Standard execution = -20 C +70 C Storage temperature range /BT option only for -LES execution = -40 C +70 C Coil resistance R at 20 C 3 3,3 Ω Max. solenoid current 2,6 Max. power L execution = 35 Watt -LE and -LES executions = 50 Watt Insulation class H (80 ) Due to the occuring surface temperatures of the solenoid coils, the European standards ISO and EN982 must be taken into account Protection degree to DIN EN L execution = IP65 -LE execution = IP67 -LES execution = IP66/67 Duty factor Continuous rating (ED=00%) EMC, climate and mechanical load See technical table G004 Size Max regulated flow at Δp =5 bar at Δp =0 bar Max permissible flow [l/min] Max pressure [bar] LIQZO LIQZP Nominal flow of pilot valve at Δp = 70 bar[l/min] Leakage of pilot valve at P = 00 bar [l/min] Piloting pressure [bar] Piloting volume [cm 3 ] Piloting flow () Response time 0 00% step signal (2) [ms] Hysteresis [% of the max flow] Repeatability [% of the max flow] Thermal drift Ports, B = 350 X = 350 Y 0 Ports, B = 420 X = 350 Y 0 min: 40% of system pressure max 350 recommended ,% ± 0,% zero point displacement < % at ΔT = 40 C Note: bove performance data refer to valves coupled with tos electronic drivers, see section.

6 DIGITL INTEGRL DRIVERS -LES - OPTIONS Standard driver execution provides on the 7 pin main connector: Power supply - 24 VDC must be appropriately stabilized or rectified and filtered; a 2,5 safety fuse is required in series to each driver power supply pply at least a 0000 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 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 ±0 VDC nominal range Following options are available to adapt standard execution special to application requirements:. 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 VDC, normal working corresponds to 24 VDC..2 Option /I It provides 4 20 m current reference and monitor signals, instead of the standard ±0 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..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 24 VDC on the enable input signal..4 Option /Z It provides, on the 2 pin main connector, the following additional features: Logic power supply Separated power supply for the solenoid (pin, 2) and for the digital electronic circuits (pin 9, 0). 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 EN3849- (ex EN954-). Enable Input Signal To enable the driver, supply 24 VDC 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 20m input, etc.). Fault presence corresponds to 0 VDC, normal working corresponds to 24 VDC (pin referred to pin 2): Fault status is not affected by the Enable input signal.5 Possible combined options: /FI, /IQ and /IZ. 2 DIGITL INTEGRL DRIVERS -LES - ELECTRONIC CONNECTIONS ND LEDS CNopen (male) CNopen (female) SPOOL POSITION MIN STGE USB (female) PROFIBUS DP (male) PROFIBUS DP (female) L L2 L3 EtherCT (female) EtherCT (female) DIGNOSTIC LED L L2 L3 2 INPUT FIELDBUS CONNECTOR OUTPUT FIELDBUS CONNECTOR MIN CONNECTOR USB CONNECTOR (always present) 7 PIN MIN CONNECTOR (male) Note: Connectors front view PE 2 PIN MIN CONNECTOR (male) LED FUNCTION DESCRIPTION -NP, -BC, -BP -EH EtherCT L VLVE STTUS LINK/CT L2 NETWORK STTUS NETWORK STTUS L3 SOLENOID STTUS LINK/CT
