In addition to the consumers of the control arrangement, an additional consumer (50) should be able to be connected to a power beyond connection. All consumers and power beyond consumers are supplied with hydraulic fluid by a pump (6). An input pressure scale (52) is provided downstream from the pump, and the greater of the load pressures of the consumers or of the at least one power beyond consumer is present on the control connection of said input pressure scale.
