Maximum protective field width for the camera system on the left
Maximum protective field width for the camera system on the right
During mounting, please observe the maximum protective field
width.
If, during mounting, the maximum protective field width for one
or two safety sensor systems is exceeded, the safety sensor will
not see the reflective tape opposite. As a result an unmonitored
area will be produced. The operator is at risk.
ATTENTION
Figure 11 - Dangerous mounting mistake: maximum protective field width
exceeded. The mounting shown here is expressly not recommended by
Rockwell Automation.
Prevent the mutual interference of systems mounted in close
proximity.
If two SC300 are so arranged that they entirely or partially look at
the same reflective tape, the two safety sensors may interfere
with each other. This can disrupt the protective function of the
system. This would mean that the operator is at risk.
Take suitable measures to prevent mutual interference:
• If the two safety sensors are used in different applications:
– Reverse the direction in which one of the systems looks.
– Choose a different mounting method (see “Steps for
mounting the safety sensor system” section on page 22).
– Mount non-reflective field of view guards.
• If the two safety sensors are used in the same application,
then synchronize the two systems (see “Two SC300 with
synchronization” section on page 30).
