RE 04/0.0 VT 504-X Hydralics Bosch Rexroth AG /0 Fnctional description The analog amplifier VT504-X/... is designed as insertion card in ero format. It is provided with a command vale inpt each for pressre and swivel angle [] as a standard (optional power limitation). The actal pressre vale is measred with a pressre transdcer. The position sensor at the pmp measres the actal vale of the swivel angle. The measred actal vales are processed in amplifier [] and [] and compared with the provided command vales. The minimm vale generator [4] controls that only controller [6] or [0] which is allocated to the reqested operating point is atomatically activated. The otpt signal of the minimm vale generator [4] becomes the command vale for the valve control loop. The optionally available power limitation is atomatically activated by the provision of a sitable command vale. The power command vale can be provided internally or externally. If necessary, it limits the swivel angle command vale by means of a minimm vale generator [5]. The reslting swivel angle command vale can be measred at socket. The actal vale of the valve (position of the valve spool) is measred with an indctive position sensor. The oscillator/demodlator circit [] is responsible for the processing of the signal. The control deviation is generated and processed in the controller for the valve spool position [8]. The otpt signal of the valve controller [8] forms the command vale for the self-timing power otpt stage [9] which controls the proportional magnet of the valve. The amplifier card has a falt message otpt with a voltage of 0 V in case of falt (= low active). At the same time, the "Err." LED flashes. Depending on the jmper J configration, the valve otpt can be sht off in case of an error message. Cases for error messages: Defective internal voltage spply Actal pressre vale is higher than the permissible system pressre (socket : p actal >.5 V) No release signal at port 6c Cable break or exceedance of the range of the swivel angle retrn Cable break or exceedance of the range of the valve spool retrn Pressre absorber cable break (for adjstments 4...0 ma, 0.5...5 V and...0 V) Control error (control difference x controller amplification) is larger than 4 V (40 %) for more than second In case of falt, the electronics can be configred so that the otpt is de-energized and the valve spool is pressed to its mechanical final position. This cases the pmp to swivel back. The error can only be acknowledged by resetting the release signal. [ ] = Allocation to the block circit diagram on page 4 and 5
