GENERAL INFORMATION ON DEVICE POSITIONING
The safety light curtain should be carefully positioned in order to provide the necessary
protection. Access to the dangerous area must only be possible by passing through the
protecting safety light beams.
Under standard operating conditions, machine starting must not be possible while
operators are inside the dangerous area.
Where it is not possible to install safety light curtain very near to the dangerous zone, a
second light curtain must be mounted in a horizontal position in order to prevent any
lateral access, as shown in the following figures.
CAUTION: The figure below 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 curtain at sufficient height
in order to completely cover the access to the dangerous area (correct
positioning) becomes necessary.

Figure 7: Correct light curtain positioning
CAUTION: If the operator is able to enter in the dangerous area, an addi-
tional mechanical protection must be mounted to prevent the access.
