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.
Figure 1 - Wrong light curtain positioning
Figure 2 - Correct light curtain positioning
CAUTION
Figure 1 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 com-
pletely cover the access to the dangerous area (Figure 2) becomes neces-
sary.
CAUTION
If the operator is able to enter in the dangerous area, an additional
mechanical protection must be mounted to prevent the access.
