Adjusmens for se zero poin or deadband compensaion and for gain allow he amplifier o be easily uned o he proporional conrol valve. The ramp funcion generaor can be swiched on and off using he ramp enable conrol. Monior poins on he fron panel allow measuremen of he condiioned command signal, and eiher of spool posiion LVDT signal or (for valves wihou LVDT) of solenoid curren. ( Condiioned command signal is he inpu signal modified according o seings of se zero poin or deadband compensaion, gain and ramp funcions.) User-friendly fron panel wih all he necessary adjusmens, LEDs and monior poins Elecronic overload proecion wih auomaic rese Pulse widh modulaion for high efficiency Can be equipped ed wih plug-in modules for special funcions Swichable ramp funcion generaor for conrolling raes of increase and decrease of oupu DC power supply Eiher curren or volage inpu signals Sandard inpu and oupu signals This produc has been designed and esed o mee specific sandards oulined in he European Elecromagneic Compaibiliy Direcive (EMC) 89/336/EEC, amended by 91/263/EEC, 92/31/EEC and 93/68/EEC, aricle 5.
