For providing an easy and efficient solution for improving a manual emergency steering with the hydraulic steering unit (5a), the hydraulic steering control system (4) provides a turn assist mode (TAM) in which the electric motor (9) supports mechanical input movements (MIL, MIR) applied to the mechanical steering input (6) by exerting additional torque in the same respective steering direction to the mechanical steering input (6). The invention further relates to a hydraulic steering system (1) and a method for controlling a hydraulic steering system (1).

The invention relates to a control system (81) for a hydraulic system (64) for moving a tool (28, 71). The control system (81) comprises a joystick (58) and an electronic controller (62). The joystick (58) includes a joystick handle (134) configured to be manipulated by an operator (22) for indicating desired movements of the tool (28, 71).

Die Erfindung betrifft ein Verfahren und eine Anlage zur Gewinnung und Nutzung von Wasserstoff, insbesondere zur Nutzung von Wasserstoff im Bereich der Galvanik. Es wird eine klimapositive Galvanik mit dem Ziel vorgestellt, den CO₂-Fuß-abdruck eines Galvanikprozesses durch die Nutzung einer innovativen Kombination aus vorhandenen Verfahren und der Nutzung des bisher ungenutzten Gasgemisches (verunreinigtes H₂) zu reduzieren.

The invention relates to a controller (80) for a pump (42) with a variable pump capacity (PPC) in a pump unit (41). It has a sensor interface (81) for receiving internal signals (ITS) and a communication interface (82) for receiving the external signals (EXS) from a first fluid circuit (10) with further pump units (41a, 41b). It obtains an individual pressure increase (IPI) over the pump (42) with the internal signals (ITS). In a normal-mode operation, it controls the pump capacity (PPC) based on the external signals (EXS). It determines if the external signals (EXS) are received no longer and/or receives a failure-indication signal from the first fluid circuit (10), and then automatically switches to a failure-mode operation. It stores reference information (RFI) based at least on a part of the external signals (EXS) in the normal-mode operation in a memory (83) and controls, in the failure-mode operation, the pump capacity (PCC) based at least on the individual pressure increase (IPI) and the reference information (RFI); and/or it controls, in the failure-mode operation, the pump capacity (PPC) based at least on the individual pressure increase (IPI), on the pump capacity (PCC), and a failure-mode specific adaptation of a deadband (DB) for controlling the pump capacity (PCC). The invention also relates to a cooling distribution unit (30) with the controller (80), a data center cooling system (1) with the latter, and a method for controlling a pump (42).
