This symbol stands by a very important warning concerning the safety of persons.
Its non-observance can cause a very serious risk for the exposed personnel.
INTRODUCTION
The JANUS TRX photoelectric barrier is a double-beam optoelectronic safety system.
It belongs to the family of Type 4 electrosensitive devices for the protection of personnel
exposed to risks arising from the use of hazardous machinery or plant, according to
standards IEC 61496-1,2 and EN 61496-1.
This barrier is composed of one active element J TRX E/R (containing the emitter and the
receiver units) and one passive element J TRX RR with a retroreflector
pre-aligned inside) which reflects the infrared beam (Figure 1).
The distance between the axis of the 2 beams (emitted and reflected) is 500mm (value
required by the EN999 European Normative for a 2-beams System).
A diagnostic display available on the active element provides the necessary informations for
a correct use of the device and the valuation of the possible operation failures.
JANUS TRX is ideal for protecting:
Automatic palletizing/depalletizing systems, packing and packaging machines, metal, wood,
marble and glass tool machines, materials handling.
If necessary, for any safety-related problems contact the competent safety
authorities or industrial associations in the country of use.
For applications in the food industry, please contact the manufacturer to ensure that
the barrier contains materials that are compatible with the chemical agents utilized.
The protective function of the optoelectronic devices is not effective in the following cases:
If the machine stopping control cannot be actuated electrically and it is not possible
to stop all dangerous machine movements immediately and at any time during the
operating cycle.
If the machine generates dangerous situations due to material being expelled or
falling from overhead.
