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. 4 FIELDUS - Fieldbus allows the direct communication of the proportional valve with machine control unit for digital reference signal, diagnostics and settings of functional parameters. Analog reference signal remain available on the main connector for quick commissioning and maintenance. For detailed information about fieldbus features and specification see tech table GS50. 5 MAIN CHARACTERISTICS - based on mineral oil ISO VG at 50 C Assembly position Any position Subplate surface finishing Roughness index, Ra 0,4 flatness ratio 0,0/00 (ISO 0) MTTFd valves according to EN ISO 49 50 years, see technical table P007 Ambient temperature range A: standard -0 C +70 C, /T option -40 C +60 C AE, AES: standard -0 C +60 C, /T option -40 C +60 C Storage temperature range A: standard -0 C +80 C, /T option -40 C +70 C AE, AES: standard -0 C +70 C, /T option -40 C +70 C Coil resistance R at 0 C Standard 3 3,3 W Option /6, W Option /8 3 3,4 W Max. solenoid current Standard,4A (,8 for /3) Option /6 3A (,5A for /3) Option /8 A (0,8A for /3) Max. power A 30 Watt AE, AES 50 Watt Insulation class H (80 ) Due to the occuring surface temperatures of the solenoid coils, the European standards ISO 373- and EN98 must be taken into account Protection degree to DIN EN6059 IP/67 with mating connectors Tropicalization (only AE, AES) Tropical coating on electronics PC Duty factor Continuous rating (ED00%) EMC, climate and mechanical load See technical table G004 Communication interface (only AE, AES) US CANopen PROFIUS DP Atos ASCII coding EN5035-4 + DS408 EN5070-/IEC658 IEC 658 Communication physical layer (only AE, AES) not insulated US.0 + US OTG optical insulated CAN ISO898 optical insulated RS485 Fast Ethernet, insulated 00 ase TX Max regulated pressure (Q l/min) [bar] Min. regulated pressure (Q l/min) () [bar] Max. pressure at port P [bar] Max. pressure at port T [bar] Max. flow [l/min] 5 3 35 0 4 Response time 0-00% step signal () [ms] (depending on installation) Hysteresis [% of the max pressure] Linearity [% of the max pressure] Repeatability [% of the max pressure] () Min pressure value to be increased of T line pressure () Average response time value; the pressure variation in consequence of a modification of the reference input signal to the valve is affected by the stiffness of the hydraulic circuit: greater is the stiffness of the circuit, faster is the dynamic response 45,5 3 Notes: above performance data refer to valves coupled with Atos electronic drivers, see section

Coil voltage Option /6 optional coil to be used with Atos drivers with power supply VDC Option /8 optional coil to be used with electronic drivers not supplied by Atos 9 ELECTRONIC OPTIONS - for AE and AES Standard driver execution provides on the 7 pin main connector: Power supply - 4VDC must be appropriately stabilized or rectified and filtered; a,5 A fuse time lag is required in series to each driver power supply. Apply at least a 0000 mf/40 V capacitance to single phase rectifiers or a 4700 mf/40 V capacitance to three phase rectifiers Reference input signal - analog differential input with 0 +0 VDC nominal range (pin D,E), proportional to desired valve pressure regulation Monitor output signal - analog output signal proportional to the actual valve s coil current (V monitor A coil current) Note: a minimum booting time of 500 ms has be considered from the driver energizing with the 4 VDC power supply before the valve has been ready to operate. During this time the current to the valve coils is switched to zero. 9. Option /I It provides 4 0 ma current reference signal, instead of the standard 0 +0 VDC. Input signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±0 V or ±0 ma. 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. Option /Q To enable the driver, supply 4 VDC on pin C referred to pin : Enable input signal allows to enable/disable the current supply to the solenoid, without removing the electrical power supply to the driver; it is used to maintain active the communication and the other driver functions when the valve has to be disabled. This condition does not comply with European Norms EN49- (ex EN954-). 9.3 Option /Z It provides, on the pin main connector, the following additional features: Enable Input Signal To enable the driver, supply 4 VDC on pin 3 referred to pin : Enable input signal allows to enable/disable the current supply to the solenoid, without removing the electrical power supply to the driver; it is used to maintain active the communication and the other driver functions when the valve has to be disabled. This condition does not comply with European Norms EN49- (ex EN954-). Fault Output Signal Fault output signal indicates fault conditions of the driver (solenoid short circuits/not connected, reference signal cable broken for 4 0mA input, etc.). Fault presence corresponds to 0 VDC, normal working corresponds to 4 VDC (pin referred to pin ): Fault status is not affected by the Enable input signal Power supply for driver s logics and communication Separate power supply (pin 9,0) allow to cut solenoid power supply (pin,) while maintaining active diagnostics, serial and fieldbus communication. A safety fuse is required in series to each driver power supply: 500 ma fast fuse 9.4 Possible combined options: /IQ, /IZ TF040
