Master/Slave Positioning
In addition to standard models (that can be positioned either horizontally or vertically),
EOS4 can be purchased in a MASTER/SLAVE configuration. This configuration comprises
two (or three) pairs of light curtains in which the two (or three) Emitters and the two (or
three) Receivers are connected in series.
Figure 3 – Examples of Master/Slave configurations
The connection cable between the master and slave may be up to 50 metres in length.
This characteristic permits configuration of an application with two light curtains
positioned one at the front and one at the rear of the dangerous machine, with a single
connection towards the machine power and control circuits (Figure 4).
