Sophisticated protection measures guarantee safe portioning

When designing its machines it’s important to Marelec to offer maximum safety. The razor-sharp blades on the portion cutters represent the greatest risk; they are barely visible due to the fast cutting movement. That’s why Pilz advised the machine builder to use a protective cover including safety fence monitoring. If the cover is opened, the non-contact, coded safety switch PSENcode ensures that the knife is immediately shut down. The safety sensors have IP69K certification and are resistant to corrosive cleaning agents – ideal for use in the food industry. Integrated short circuit diagnostics offer safety up to PL e. The safe configurable small controller PNOZmulti 2 is used to control the safety functions. If the PLC controller performs a restart, PNOZmulti 2 checks that all the safety conditions have been met. Equipped like this, nothing stands in the way of safe portioning.
