For E-C-S-US/M cable fieldbus versions, the software permits valve's parameterization through US port also if the driver is connected to the central machine unit via fieldbus. The software is available in different versions according to the driver s options: E-SW-ASIC support: NP (US) PS (Serial) IR (Infrared) E-SW-FIELUS support: C (CANopen) P (PROFIUS P) EH () EW (POWERLINK) EI (EtherNet/IP) E-SW-*/PQ support: valves with SP, SF, SL alternated control (e.g. E-SW-ASIC/PQ) WARNING: drivers US port is not isolated! E-A-S-US/OPT isolator The use of isolator adapter is highly recommended for PC protection (see table GS500)

5 9 HYRAULIC OPTIONS 9. Option / -05 and -5: solenoid and integral electronics at side of port A of the main stage. -07 and -7: integral electronics at side of port A of the main stage. 9. Option /Y External drain advisable when the valve is used in double flow path, see section 7.5. Option /Y is mandatory if the pressure in port T exceeds 0 bar. 0 OPTIONS for -A 0. Coil voltage Option /6 Option /8 optional coil to be used with Atos drivers with power supply VC optional coil to be used with electronic drivers not supplied by Atos 0. Hand lever This option is available only for -A with spool type S3, S5, 3, 5, L3, L5. It allows to operate the valve in absence of electrical power supply. For detailed description of -A with hand lever option see tech. table E38 Option /MO horizontal hand lever Option /MV vertical hand lever Option /MO horizontal hand lever installed at side of port A Option /MV vertical hand lever installed at side of port A The following supplementary options allow to operate the valve in absence of electrical power supply by means of a micrometric screw replacing the standard solenoid manual override, see tech. table TK50 Option /N manual micrometric adjustment Option /NV as /N plus handwheel and graduated scale CH 0 Option /N Option /NV ELECTRONIC OPTIONS for AE and AES Standard driver execution provides on the 7 pin main connector: Power supply - 4 VC must be appropriately stabilized or rectified and filtered;,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 VC nominal range (pin, E), proportional to desired coil current 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 VC power supply before the valve has been ready to operate. uring this time the current to the valve coils is switched to zero.. Option /I It provides 4 0 ma current reference signal, instead of the standard ±0 V. 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.. Option /Q To enable the driver, supply 4 VC 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 EN3849- (ex EN954-)..3 Option /Z It provides, on the pin main connector, the following additional features: Enable Input Signal To enable the driver, supply 4 VC 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 EN3849- (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 VC, normal working corresponds to 4 VC (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, US and fieldbus communication. A safety fuse is required in series to each driver power supply: 500 ma fast fuse..4 Option /W - only for valves coupled with pressure compensator type HC-0 or KC-0 (see tab. 50). It provides, on the pin main connector, the above option /Z features plus the hydraulic power limitation function. The driver receives the flow reference signal by the analog input INPUT+ and a pressure transducer, installed in the hydraulic system, has to be connected to the driver s analog input TR. When the actual requested hydraulic power pxq (TR x INPUT+) reaches the max power limit (pxq), internally set by software, the driver automatically reduces the flow regulation of the valve. The higher is the pressure feedback the lower is the valve s regulated flow: Flow regulation Min ( PowerLimit [sw setting] Transducer Pressure [TR] For detailed information on hydraulic power limitation, see tab. GS5 ; Flow Reference [INPUT+]).5 Option /C - only in combination with option /W Option /C is available to connect pressure transducer with 4 0 ma current output signal, instead of the standard 0 0V. Input signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±0 V or ±0 ma..6 Possible combined options: /IQ, /IZ, /IW, /CW and /CWI FS60
