Resolution and safety distance when using the “Reduced blanking” function
Reduced resolution requires that the safety distance is calculated with the respective effective resolution
corresponding to the following table instead of the physical resolution specified on the name plate.
Table 6.6: Change of the effective resolution via the “Reduced resolution” function
 Add the scanning time needed for the largest beam area with floating blanking to the response time.
6.1.6 Preventing mutual interference between adjacent devices
If a receiver is located in the beam path of an adjacent transmitter, optical crosstalk, and thus erroneous
switching and failure of the protective function, may result (see figure 6.4).
1 Transmitter 1
2 Receiver 1
3 Transmitter 2
4 Receiver 2
Figure 6.4: Optical crosstalk between adjacent safety sensors (transmitter 1 influences receiver 2) due
to incorrect mounting
 Mount adjacent devices with a shield between them or install a dividing wall to prevent mutual interfer-
ence.
 Mount the adjacent devices opposite from one another to prevent mutual interference.
