SG4-B Series Instruction Manual

The device consists in 2 units that, according to the model, are
composed by one or several emitting and receiving modules. The
receiver checks the control operations and safety actions.
During installation, an user interface facilitates the alignment of both
units (see section 5 “Alignment procedure”).
As soon as an object, a limb or the operator’s body accidentally
interrupts one or some of the infrared beams sent by the emitter, the
receiver immediately opens the OSSD outputs and blocks the MPCE
machine (if correctly connected to the OSSD).
Some parts or sections of this manual containing important
information for the user or installing operator are preceded by a note:

The information provided in the paragraphs following this symbol is
