Abstract: A warehouse system comprising a control device; a plurality of racks defining rack aisles each of which includes an access and is secured against unauthorized entry by an operator by the access, wherein a first sensor monitors whether the access is closed or open and transmits corresponding status signals to the control device; a plurality of rack serving units each of which travels in an automated manner along a rack aisle and includes a load handling device for storing and retrieving storage goods. Each load handling device has assigned a second sensor which detects whether the load handling device is in a retracted neutral position, currently extracts, or is extracted, and which transmits a corresponding state signal to the control device. The system further includes an aisle-serving switch device that communicates with the control device and can be shifted physically by an access key between automatic and maintenance positions.

Abstract: It is disclosed a warehouse system comprising: a control device; a plurality of racks defining a plurality of rack aisles therebetween, wherein each of the rack aisles comprises an access and is secured against unauthorized entry by an operator by means of the access, which is locked and unlocked by means of an access key, wherein a first sensor monitors, whether the access is closed or open, and transmits corresponding status signals to the control device; a plurality of rack serving units, wherein in each of the rack aisles at least respectively one rack serving unit can travel in an automated manner at least along a longitudinal direction of the rack aisle and wherein each of the rack serving units comprises at least one load handling device or shuttle, which can be extracted and retracted on both sides along a transverse direction, for storing and retrieving storage goods in an automatic mode in and from each of the racks in an automated manner, the racks being arranged directly adjacent to the respective
