using the formula according to EN ISO 13855.
K [mm/s] = 1600
T [s] = (0.140 + 0.014 + 0.010)
C [mm] = 1200
S [mm] = 1600 mm/s  0.164 s + 1200 mm
S [mm]= 1463
A suitable safety sensor has been found; its protective field height is 1500 mm.
The following changes should now be taken into account in this example of the application conditions:
Small parts are occasionally thrown out of the machine; these can fall through the protective field. This
should not trigger the safety function. In addition, the installation height is increased to 300 mm.
There are two ways to solve this:
• DoubleScan or MaxiScan
• Reduced resolution
DoubleScan or MaxiScan: They increase the response time so that a longer device can be used, if neces-
sary.
DoubleScan
K [mm/s] = 1600
T [s] = (0.140 + 0.028 + 0.010)
C [mm] = 1200 - 0.4  300
S [mm] = 1600 mm/s  0.178 s + 1080 mm
S [mm]= 1365
MaxiScan
K [mm/s] = 1600
T [s] = (0.140 + 0.100 + 0.010)
C [mm] = 1200 - 0.4  300
S [mm] = 1600 mm/s  0.250 s + 1080 mm
S [mm]= 1480
Both methods are suitable. MaxiScan is preferred because it is sturdier.
Reduced resolution: The effective resolution for 1-beam reduction and 40 mm resolution is 64 mm and is
therefore suitable at an installation height of 300 mm (up to 70 mm resolution). The falling pieces must be
small enough that they interrupt no more than one beam.
K [mm/s] = 1600
T [s] = (0.140 + 0.013 + 0.010)
C [mm] = 1200 - 0.4  300
S [mm] = 1600 mm/s  0.163 s + 1080 mm

Please note that the start/restart interlock in the device is deactivated in operating modes 1, 2, 3
with SingleScan and DoubleScan. It must be implemented in the downstream machine control.
