Functional descriptionThe analog amplifier VT5041-3X/... is designed as insertion card in euro format. It is provided with a command value input each for pressure and swivel angle [1] as a standard (option-al power limitation). The actual pressure value is measured with a pressure transducer. The position sensor at the pump measures the actual value of the swivel angle. The measured actual values are processed in amplifier [2] and [3] and com-pared with the provided command values. The minimum val-ue generator [4] controls that only controller [6] or [10] which is allocated to the requested operating point is automatically activated. The output signal of the minimum value genera-tor [4] becomes the command value for the valve control loop.The optionally available power limitation is automatically ac-tivated by the provision of a suitable command value. The power command value can be provided internally or external-ly. If necessary, it limits the swivel angle command value by means of a minimum value generator [5]. The resulting swivel angle command value can be measured at socket 7.The actual value of the valve (position of the valve spool) is measured with an inductive position sensor. The oscillator/de-modulator circuit [7] 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 output sig-nal of the valve controller [8] forms the command value for the self-timing power output stage [9] which controls the pro-portional magnet of the valve.

The amplifier card has a fault message output with a voltage of 0 V in case of fault (= low active). At the same time, the "Err." LED flashes. Depending on the jumper J1 configuration, the valve output can be shut off in case of an error message.Causes for error messages:– Defective internal voltage supply– Actual pressure value is higher than the permissible system

pressure (socket 2: pactual > 11.5 V)– No release signal at port 26c – Cable break or exceedance of the range of the swivel

angle return– Cable break or exceedance of the range of the valve

spool return– “Pressure absorber” cable break (for adjustments

4...20 mA, 0.5...5 V and 1...10 V)– Control error (control difference x controller amplification) is

larger than 4 V (40 %) for more than 1 secondIn case of fault, the electronics can be configured so that the output is de-energized and the valve spool is pressed to its mechanical final position. This causes the pump to swivel back. The error can only be acknowledged by resetting the release signal.
