3.2 GENERAL INFORMATION ON DEVICE POSITIONING
Pay special care when positioning the safety light curtain so to offer effective protection. The device should
be installed in such a way that the dangerous area can only be entered after detecting the sensitive area.
Figure 9 shows some examples of possible access to the machine from the top and the
bottom sides. These situations may be very dangerous and so the installation of the
safety light curtain at sufficient height in order to completely cover the access to the
dangerous area becomes necessary (see Figure 10).
Figure 9
Figure 10
Under standard operating conditions, machine starting must not be possible while operators are inside the
dangerous area.
When the installation of the safety light curtain very near to the dangerous area is not possible, a second
light curtain must be mounted in a horizontal position in order to prevent any lateral access, as shown in
Figure 12
If the operator is able to enter the dangerous area, an additional mechanical protection must be
mounted to prevent the access.
