SUMMARY: Control electronics, external 3X
Quantity in stock: 0
The analog control electronics 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 (optional power limitation). The actual pressure value is measured with a pressure transducer. The position transducer at the pump measures the actual swivel angle value. The measured actual values are processed in amplifier [2] and [3] and compared with the provided command values. The minimum value 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 generator [4] becomes the command value for the valve control loop. The optionally available power limitation is automatically activated by the provision of a suitable command value. The power command value can be provided internally or externally. 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 valve value (position of the valve spool) is measured with an inductive position transducer. An oscillator/demodulator switch [7] enhances the signal. The control deviation is generated and processed in the controller for the valve spool position [8]. The output signal of the valve controller [8] forms the command value for the self-timing power output stage [9] which controls the proportional solenoid of the valve.
The control electronics is equipped with a fault message output where a voltage of 0 V is applied in an error case (= low-active). At the same time, the "Err." LED flashes. Depending on the jumper J1 configuration, the valve output stage can be de-energized in case of an error message.
Causes for fault messages:
Error in the internal voltage supply The actual pressure value is greater than the admissible system pressure (socket 2: pact > 11.5 V) No enable signal at port 26c Cable break or range of the swivel angle return exceeded Cable break or range of the valve spool return exceeded Cable break "pressure transducer" (for adjustments 4...20 mA, 0.5...5 V and 1...10 V) Control error (control difference x controller amplification) is greater than 4 V (40 %) for more than 1 secondIn an error case, the electronics can be configured so that the output stage is de-energized and the valve spool is pressed to its mechanical end position. This causes the pump to swivel back. The error can only be acknowledged by resetting the enable signal.
