Proportional reducing valves type AGRCZO-AES two stages, normally closed, without integral pressure transducer, ISO 5781 size 10 and 20 AGRCZO are two-stage normally closed proportional pressure reducing valves without integral pressure transducer, which provide pressure regulation proportional to electronic reference signal. They operate in association with electronic drivers, see table ‫ ݘ‬which supply the proportional valve with proper current signal to align valve regulation to the reference signal supplied to the electronic driver. They are available in different executions: • -A, without integral pressure transducer. • -AE, -AES, as -A plus analogue (AE) or digital (AES) integral electronics ቦ. The piloting pressure to the poppet ‫ ܨ‬is modulated by a proportional pressure relief valve type RZMO ‫ ,ܩ‬see tab. F007. A modular pressure compensated flow control cartridge ‫ ܪ‬assures constant pilot flow and therefore high pressure stability.

Standard 7 pin connector is used for power supply, analog input reference and monitor signals. 12 pin connector is used option /Z (AES). Following communication interfaces ቨ, ቩ, ቪ, ቫ are available for the digital -AES execution: • -PS, Serial communication interface for configuration, monitoring and firmware updating through Atos PC software - always present also for -BC, -BP and -EH options • -BC, CANopen interface • -BP, PROFIBUS DP interface • -EH, EtherCAT interface The valves with -BC and -BP interfaces can be integrated into a fieldbus communication network and thus digitally operated by the machine control unit.

GENERAL NOTES AGRCZO proportional valves 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...

DIGITAL INTEGRAL DRIVERS -AES - OPTIONS Standard driver execution provides on the 7 pin main connector: Power supply - 24VDC must be appropriately stabilized or rectified and filtered; a 2,5 A safety fuse is required in series to each driver power supply Apply at least a 10000 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÷+10 VDC nominal range (pin D, E), proportional to desired coil current (4÷20 mA with cable break detection, ± 10 mA, ± 20 mA or 0÷20 mA software selectable)...
