2.1 General description
The Orion3 Base light grids are Active Opto-electronic Protective Devices (AOPDs) that are used to protect working
areas that, in presence of machines, robots, and automatic systems in general, can become hazardous for operators
that get in touch, even accidentally, with moving parts.
The Orion3 Base light grids are Type 4 safety systems used as accident-prevention protection devices and are
manufactured in accordance with the international standards in force for safety, in particular:

The device, consisting of one active unit and one passive unit housed inside strong aluminium profiles, generates
infrared beams reflected by the mirrors in the passive unit and detects an opaque object interrupting a beam. The
active unit is composed by one or several emitting and receiving modules.
The active unit is equipped with the command and control functions. It checks the control operations and safety
actions. The passive unit is composed of a sturdy aluminium profile containing pre-assembled and pre-aligned mirrors.
The microprocessors guarantee the check and the management of the beams that are sent and received and the
microprocessors inform the operator about the general conditions of the AOPD via a display (see paragraph
8
– “Diagnostic functions”).
The connections are made through a M12 connector located in the lower side of the profile of the active unit.
During installation, a display facilitates the alignment of both units (see paragraph 6
– “Alignment procedure”).
As soon as an object, a limb
or the operator’s body accidentally interrupts one or several of the infrared beams sent by
the transmitter, the OSSD outputs switch off and block the Machine Primary Control Element, MPCE (if correctly
connected to the OSSD outputs).
