The operate in assoiation with eletroni drivers, see setion, whih suppl the proptional valves with proper urrent to align valve regulation to the referene signal supplied to the eletroni driver. The are available in different exeutions: L, with two integral position transduers, ; LE, LES as L plus analogue (LE) digital (LES) integral eletronis. The regulation is operated b means of a spool with double piloting area sliding into a sleeve and provided of integral LVDT position transduer. The spool is operated b means of a high perfmanes proptional diretional valve in rugged exeutions to withstand high vibrations and mehanial stresses (tpe DLZO f artridge dimensions up to size 50 and tpe DLK ZOR f artridge dimensions up to size 80) see tab. F80, provided of high preision sleeve and LVDT position transduer f maximum regulating aura and dnami response. It is ontrolled in double losed loop position b means of the LVDT position transduers and. The integral eletronis ensures fat presetting, fine funtionalit plus valvetovalve interhangeabilit and simplified wiring and installation. Standard 7 pin main onnet is used f power suppl, analog input referene and monit signals. pin onnet is used f options /Z and /S*. The speial /S* options add a losed loop ontrol of pressure (/SP) fe (/SL) to the basi losed loop spool position one. Following ommuniation interfaes are available f the digital LES exeution: PS, Serial ommuniation interfae. The valve referene signal is provided with analogue ommands BC, CANopen interfae BP, PROFIBUS DP interfae The valves with BC and BP interfaes an be integrated into a fieldbus ommuniation netwk and thus digitall operated b the mahine ontrol unit. Tpial appliations: plasti injetion and blow moulding, eramis, punhing & nibbling mahines, dieasting, foundr and sheet mahiner; Mounting surfae: ISO 768 Sizes from 5 to 80 Max flow up to 00 l/min with differential pressure Δp = 5 bar, see setion ; Max pressure = 50 bar.

Installation, wirings and startup proedures must be perfmed ading to the general presriptions shown in table F00 and in the installation notes supplied with relevant omponents. The eletrial signals of the valve (e.g. monit signals) must not be diretl used to ativate safet funtions, like to swithon/off the mahine s safet omponents, as presribed b the European standards (Safet requirements of fluid tehnolog sstems and omponentshdraulis, EN98).. Option /A The standard valve version provides the hdrauli onfiguration AT of main spool in absene of eletri power suppl to the valve. The option /A provides the reversed onfiguration PA of main spool in absene of eletri power suppl to the valve. This exeution is partiularl requested in vertial presses f safet reasons, beause in ase of eletri power breakdown the valve PA onfiguration of the main spool prevents the unontrolled and dangerous downstroke of the press ram. 5 CONNECTIONS FOR L EXECUTION SOLENOID POWER SUPPLY CONNECTOR PIN Signal desription SUPPLY SUPPLY GND PIN POSITION TRANSDUCER CONNECTOR (pilot and main stage) Signal desription OUTPUT SIGNAL SUPPLY 5 VDC SUPPLY +5 VDC GND MAIN STAGE POSITION TRANSDUCER CONNECTOR PIN SIZES 6 0 SIZE Signal desription PIN Signal desription OUTPUT SIGNAL OUTPUT SIGNAL SUPPLY 5 VDC NOT CONNECTED SUPPLY +5 VDC SUPPLY + VDC GND GND 6 ANALOG INTEGRAL DRIVERS LE OPTIONS Standard driver exeution provides on the 7 pin main onnet: Power suppl VDC must be appropriatel stabilized retified and filtered; a,5 A safet fuse is required in series to the driver power suppl Appl at least a 0000 μf/0 V apaitane to single phase retifiers a 700 μf/0 V apaitane to three phase retifiers Referene input signal analog differential input with ±0 VDC nominal range (pin D,E), proptional to desired valve spool position Monit output signal analog output signal proptional to the atual valve s spool position with ±0 VDC nominal range Following options are available to adapt standard exeution to speial appliation requirements: 6.

Option /I It provides 0 ma urrent referene and monit signals instead of the standard ±0 V. It is nmall used in ase of long distane between the mahine ontrol unit and the valve where the referene signal an be affeted b eletrial noise; the valve funtioning is disabled in ase of referene signal able breakage. 8. Option /Z It provides on a pin main onnet the above standard features plus: Logi power suppl Option /Z provides separate power suppl f the solenoid (pin, ) and f the digital eletroni iruits (pin 9, 0). Cutting solenoid power suppl allows to interrupt the valve funtioning but keeping energized the digital eletronis thus avoiding fault onditions of the mahine fieldbus ontroller. This ondition allows to realize safet sstems in ompliane with European Nms EN89 (ex EN95). Enable Input Signal To enable the driver, suppl a VDC on pin referred to pin : when the Enable signal is set to zero the valve funtioning is disabled (zero urrent to the solenoid) but the driver urrent output stage is still ative. This ondition does not ompl with European Nms EN89 (ex EN95). Fault Output Signal Fault output signal indiates fault onditions of the driver (solenoid sht iruits/not onneted, referene signal able broken f 0mA input, et.). Fault presene responds to 0 VDC, nmal wking responds to VDC (pin referred to pin ): Fault status is not affeted b the Enable input signal 8. Options /SP and /SL These options add the losed loop ontrol of pressure (/SP) fe (/SL) to the basi funtions of proptional diretional valves: a dediated software alternates pressure (fe) and valve s spool position ontrols depending on the atual hdrauli sstem onditions. A dediated onnet is available f the additional transduers that are required to be interfaed to the valve s driver ( pressure transduer f /SP load ell f /SL). Main pin onnet is the same as /Z option plus two analog signals speifi f the pressure (fe) ontrol: one f referene (pin 7) and one f monit (pin 8). F futher details please refer to the driver tehnial table G. 8. Options /C Options /CSP and /CSL are available to onnet pressure (fe) transduers with 0mA urrent output signal. 8.5 Possible ombined options: /ISP, ISL, /CSP, /CSL, /CISP, /CISL and /IZ F0
