Beschreibung
Zusammenfassung:	The invention discloses a hydraulic machine assembly with a pre-control valve. The pre-control valve is used for adjusting a hydraulic machine arranged in the hydraulic machine assembly. The pre-control valve has a valve body, the position of which can be detected by a displacement measuring system. Furthermore, control electronics are provided, by means of which a self-test of the hydraulic machine assembly can be carried out. The self-test is performed only when the controller obtains a self-test release signal. 本发明公开了一种具有预控制阀的液压机组件，该预控制阀用于调节设置在液压机组件中的液压机。预控制阀具有如下阀芯，该阀芯的位置能够通过位移测量系统来检测。此外，设置有如下控制电子器件，通过该控制电子器件可执行液压机组件的自测试。只有当控制器获得自测试释放信号时，才执行所述自测试。
