MLC 530 SPG Smart Process Gating
The MLC 530 SPG safety light curtains with Smart Process Gating offer a space-saving alternative for access guarding on conveyor lines. With this innovative technology, process control takes place in combination with the system control. This solution requires no muting sensors and operates exceptionally reliably.
No trigger sensors required
With Smart Process Gating, process control takes place in combination with the system control. A switching signal provided by the PLC and interruption of the protective field by the transported goods are used as triggers for activation of the gating function. No additional trigger sensors are required.
Operating principle and signal response of SPG
The gating function (bridging of the protective field) is activated by the correct sequence of switching signal and protective field violation and monitored by the light curtain. The gating ends either automatically or – in the case of higher conveyor line speeds – by resetting of the switching signal.
