Calculation of safety distance S
RO
when the height of the upper beam has changed:
The height of the upper beam is now 900 mm. All other parameters remain the same. C
RO
= 1050 mm see
table 6.2.
K
[mm/s]
= 1600 mm/s
T
[ms]
= 335 ms
C
RO
[mm]
= 1050 mm
S
[mm]
= 1600 mm/s × 0.335 s + 1050 mm
S
RO
[mm]
= 1586 mm
This means S
RO
> S, so S

is to be used!
6.1.5 Minimum distance to reflective surfaces
WARNING
Failure to maintain minimum distances to reflective surfaces may result in serious injury!
Reflective surfaces can indirectly deflect the transmitter beams to the receiver. In this case, interruption
of the protective field is not detected.
Determine the minimum distance a see figure 6.3.
Make certain that all reflective surfaces are the necessary minimum distance away from the protective
field see figure 6.4and see figure 6.5.
