Cascading

During cascading, the safety outputs of a safety light grid are connected to an evaluation
device. A second safety light grid can be connected to this first safety light grid. The first
safety light grid is the master unit; the safety light grid connected to the master unit is the
slave unit.
Max. 2 slave units to one master unit
}
Max. overall length: 3600 mm
}
The master unit collects the results from the slave units and ensures synchronisation
}
between them, so that mutual interference is avoided
Each transmitter/receiver in the PSEN op2H-SL Series can be used both as a master
}
unit and a slave unit
Up to three areas can be monitored when two safety outputs are connected
}

Project configuration

Maintaining the safety distance

The minimum distance between the safety light grid and the hazardous machine compon-
ent should be such that the operator cannot reach the hazardous area until the hazardous
machine part has come to a standstill.
