Control electronics VT 504 /0 Fnctional description The analog control electronics 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 transdcer at the pmp measres the actal swivel angle vale. 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 valve vale (position of the valve spool) is measred with an indctive position transdcer. An oscillator/demodlator switch [] enhances 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 solenoid of the valve. The control electronics is eqipped with a falt message otpt where a voltage of 0 V is applied in case of error (= low-active). At the same time, the "Err." LED flashes. Depending on the jmper J configration, the valve otpt can be de-energized in case of an error message. Cases for error messages: Defective internal voltage spply The actal pressre vale is greater than the admissible system pressre (socket : p act >.5 V) No enable signal at port 6c Cable break or range of the swivel angle retrn exceeded Cable break or range of the valve spool retrn exceeded Cable break "pressre transdcer" (for adjstments 4...0 ma, 0.5...5 V and...0 V) Control error (control difference x controller amplification) is greater than 4 V (40%) for more than second In case of error, the electronics can be configred so that the otpt stage is de-energized and the valve spool is pressed to its mechanical end position. This cases the pmp to swivel back. The error can only be acknowledged by resetting the enable signal. [ ] = assignment to the block diagram on page 4 and 5 RE 04, edition: 0-06, Bosch Rexroth AG
