Immunity/Emission EMC Directive and Low Voltage Directive). Installation, wirings and startup procedures must be performed according to the general prescriptions shown in table F00 and in the installation notes supplied with relevant components. he electrical signals of the valve (e.g. monitor signals) must not be directly used to activate safety functions or components, as prescribed by the European standards (Safety requirements of fluid technology systems and componentshydraulics, EN92). FIELDUS only for RES 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 GS10.

4 9 HYDRAULIC OPIONS 9.1 Option /P integral mechanical pressure limiter (standard for size 1, 2 and ) LICZOR*, LIMZOR* and LIRZOR* standard size 1, 2, and option /P are provided with mechanical pressure limiter acting as protection against overpressure. For safety reasons the factory setting of the mechanical pressure limiter is fully unloaded (min pressure). At the first commissioning it must be set at a value lightly higher than the max pressure regulated with the proportional control. For the pressure setting of the mechanical pressure limiter, proceed according to following steps: apply the max reference input signal to the valve s driver. he system pressure will not increase until the mechanical pressure limiter remains unloaded. turn clockwise the adjustment screw until the system pressure will increase up to a stable value corresponding to the pressure setpoint at max reference input signal. turn clockwise the adjustment screw of additional 1 or 2 turns to ensure that the mechanical pressure limiter remains closed during the proportional valve working. adjustment screw locking nut CH CH CH CH protection cap 10 DIAGRAMS (based on mineral oil ISO VG at 0 C) 1 Regulation diagrams LICZO, LIMZO 2 Pressure/flow diagrams LICZO, LIMZO Pressure at port A [% of the max] 1 Regulated pressure at port A [bar] 2 Reference signal [% of max.] Flow [% of the max] 1 Min. pressure/flow diagrams with zero reference signal = LIMZO*1 = LICZO*1 = LIMZO*2 7 = LICZO*2 = LIMZO* = LICZO* 11 = LIMZO* 9 = LICZO* 12 = LIMZO* 10 = LICZO* 1 = LIMZO* Note: for LIMZO* consult our technical office Min. regulated pressure [bar] 7 Min. regulated pressure [bar] Flow [l/min] Flow [l/min] 1 Regulation diagrams LIRZO 11 Min. pressure/flow diagrams with zero reference signal 1 = LIRZO*1 1 = LIRZO*2 17 = LIRZO* 1 = LIRZO* dotted line = / Pressure at port A [% of the max] 1 Differential pressure A Reference signal [% of max.] Flow [l/min] 19 Pressure/flow diagrams LIRZO Regulated pressure at port A [bar] 19 Flow [% of the max]

5 11 DYNAMIC RESPONSE pressure PIDs he valve is provided with PIDs configurations to match different hydraulic conditions. he required PID configuration can be selected before the valve commissioning, through Atos ESW software via US port. Only for RES the PID can be also selected in real time, through PLC via fieldbus.

Apply at least a mf/0 V capacitance to single phase rectifiers or a 700 mf/0 V capacitance to three phase rectifiers Reference input signal analog differential input with VDC nominal range (pin D,E), proportional to desired valve pressure regulation Monitor output signal analog output signal proportional to the actual valve pressure regulation = VDC nominal range Note: a minimum booting time of 00 ms has be considered from the driver energizing with the 2 VDC power supply before the valve has been ready to operate. During this time the current to the valve coils is switched to zero. 1.1 Option /I It provides 20 ma current reference and monitor signals, instead of the standard VDC. Input signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±10 V or ±20 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 1.2 Option /Q o enable the driver, supply 2 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. his condition does not comply with European Norms EN191 (ex EN91). 1. Option /Z It provides, on the 12 pin main connector, the following additional features: Enable Input Signal o enable the driver, supply 2 VDC on pin referred to pin 2: 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. his condition does not comply with European Norms EN191 (ex EN91). Fault Output Signal Fault output signal indicates fault conditions of the driver (solenoid short circuits/not connected, reference signal cable broken for 20mA input, etc.). Fault presence corresponds to 0 VDC, normal working corresponds to 2 VDC (pin 11 referred to pin 2): Fault status is not affected by the Enable input signal Power supply for driver s logics and communication Separate power supply (pin 9,10) allow to cut solenoid power supply (pin 1,2) while maintaining active diagnostics, US and fieldbus communication. A safety fuse is required in series to each driver power supply: 00 ma fast fuse. 1. Possible combined options: /IQ, /IZ 1 PROGRAMMING OOLS see tech table GS00 US connection Valve's functional parameters and configurations, can be easily set and optimized using Atos ESW programming software connected via US port to the digital driver. For ECSUS/M12 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. he software is available in different versions according to the driver s options: ESWASIC support: NP (US) PS (Serial) IR (Infrared) ESWFIELDUS support: C (CANopen) P (PROFIUS DP) EH (EtherCA) EW (POWERLINK) EI (EtherNet/IP) ESW*/PQ support: valves with SP, SF, SL alternated control (e.g. ESWASIC/PQ) WARNING: drivers US port is not isolated!
