Reer VISION VX User Manual

8540571 - 25/08/2016 - Rev.15 7
In addition to the standard VISION models, VISION VX is available in the MASTER/SLAVE
configuration. Such configuration is made of two pairs of light curtains, where the two
emitters and the two receivers are respectively connected in series.
The most common application is shown in Figure 3: the horizontal light curtain (A) has been
installed to detect the presence of a person between the vertical light curtain (B) and the
dangerous machine at system power-up or restart.
Figure 3
The length of the connection cable between the master and the slave can be up to 50 m.
This makes it possible to install two light curtains - one at the front and the other at the rear
of the machine – with just one connection to the power and control circuits of the machine.
