Abstract

A pressure control installation for presses in which the individual pressure consuming stations are to be actuated with different pressures. During the setting up of the presses, it is necessary to fetch and display visible for the operator values adjusted during the optimization and interim value. The pressure control units, whose number depends on the number of differing high pressures, are connected by way of an interface component to a stored programmable control SPS. The read-out of the data in the pressure control unit takes place by way of a read-out key whereby a routine is initiated it the SPS during the actuation of the read-out key for the guidance of the operator.
