Пропорциональные распределители 4/3 со встроенной цифровой электроникой и интерфейсом полевой шины (IFB-P) 4WREF

Description Size 6, 10 Component series 2X Maximum operating pressure 315 bar Maximum flow 180 l/min Features Direct operated proportional directional valve with integrated digital electronics and field bus interface (Integrated Field Bus IFB-P) Operation by means of proportional solenoids with central thread and detachable coil Valve control spool, position-controlled Analog interface for command and actual value Command value (flow), analog or via bus Design for CAN bus with CANopen protocol DS 408 or Profibus-DP Quick commissioning via PC and WIN-PED 6 commissioning software Product description Set-up: The valve basically consists of: Housing (1) with connection surface Control spool (2) with compression springs (3 and 4) and spring plates (8 and 9) Coils (5 and 6) and pole tubes (10 and 11) with central thread Position transducer (7) Integrated digital control electronics IFB-P (12) Control of the valve spool position The command value presetting can alternatively be specified via an analog interface (X1) or via the field bus interface (X2, X3) The actual value signals are provided via an analog interface (X1) and can additionally be read out via the field bus (X2, X3) The controller parameters are set via the field bus Undervoltage Cable break position transducer (7) Communication error Watchdog Cable break command value input (only with current interface) Ramp generator Internal command value profile Enable function, digital Overlap compensation Zero point correction Parameterization Diagnosis Comfortable data management on a PC IBM PC or compatible system Windows 2000 or Windows XP RAM (recommendation: 256 MB) 150 MB of available hard disk capacity Functional description With de-energized solenoids (5 and 6), the control spool (2) is brought into the central position by compression springs (3 and 4) between the spring plates (8 and 9) (with V control spool without spring plate). With V control spools, the mechanical zero position does not correspond to the hydraulic one. Functions: The integrated digital electronics enables the following error detection: The following additional functions are available: WIN-PED PC program (version 6 or higher): To implement the project planning task and to parameterize the IFB-P valves, the user may use the WIN-PED commissioning software. System requirements Notice The "WIN-PED" PC program is not included in the scope of delivery. It is available for free download! Important notice: The PG fitting (13) must not be opened. Mechanical adjustment of the adjustment nut located below is prohibited and damages the valve! Notice! Due to the design principle, internal leakage is inherent to the valves, which may increase over the life cycle. The tank line must not be allowed to run empty. With corresponding installation conditions, a preload valve must be installed.
