MLC 530 SPG Smart Process Gating

Access guarding with Smart Process Gating - The innovation without "muting sensors"

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.

Advantages for you

Allows a particularly compact and space‑saving system design because no additional trigger sensors are necessary
Reliable passage of transported goods through the system, even with incomplete or changing loads
No service calls required for trigger sensor alignment
The process starts only in combination with the system control and cannot be bypassed by the operating personnel. This provides optimum protection.

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

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 after the transported goods pass through or – in the case of higher conveyor line speeds – by resetting the switching signal.

Applications

Requirement:
Access guarding on the pallet conveyor systems is to prevent persons from accessing the danger zone, while at the same time allowing the transported goods to pass through.

Solution:
The MLC 530 SPG safety light curtains with Smart Process Gating require no additional muting sensors for bridging for the transported goods. As a result, the output stations can be designed in an especially compact and space-saving manner.

Access guarding on conveyor lines, with Smart Process Gating

Requirement:
Access guarding needs to prevent persons from entering the danger zone, while at the same time allowing car bodies to be transported into these areas. In addition, the closed state of the pendulum flaps is also to be monitored.

Solution:
The MLC 530 SPG safety light curtains with Smart Process Gating require no additional muting sensors for bridging for the transported goods. The space-saving solution guarantees high availability and high protection against manipulation. With the partial gating function, the safety light curtain uses its upper beams – which are always active – to simultaneously monitor the pendulum flaps as well.
