The compartment 1 control is used in storage systems with a chaotic storage principle and multiple loading heights. It is intended to prevent a pallet from being pushed into a compartment into which material from the pallet below is protruding. A compartment-1 check is required whenever the SRM system is about to push a pallet into a rack compartment. This check does not have to be carried out when moving to a station or when the SRM is empty.
