As "rotary packing systems" the machines have particularly complex safety requirements. Up to 16 filling spouts rotate around a central axis. If each of these filling spouts will be protected separately with conventional, i.e. hard-wired, safety relays and contactors, this means high technical effort, high space requirements and considerable costs. 

The SIRIUS 3SK2 safety relays can be parameterized via software and are therefore flexibly adaptable. The parameters can be easily transferred to several machines using a USB cable or via a fieldbus/Profinet interface. Since the safety relays operate independently of the controller, they can be easily integrated into any automation environment. The SIRIUS ACT ID key-operated switches complement the safety concept. They permit modern access management and unique authentication (using RFID chips) of users.
