“Smart Process Gating” is the name of a new process from Leuze electronic through which muting processes are made more economical, simpler and safer.
In the past, muting sensors were required in order to clearly identify when goods were approaching a protective field. As a result of the SPG (Smart Process Gating) method these sensors are no longer needed which allows the systems, which are based on the Leuze MLC safety light curtains, to be much more compact thus saving space. The risk of misalignment or damage to the sensors is eliminated as is the costs for their maintenance and servicing. Furthermore, the purchasing costs, the wiring and risk of manipulation are reduced which increases the reliability of the complete safety device. With SPG, the first muting signal comes from the process control (PLC), while the second muting signal is generated by the protective field itself.
