Switching Position At The End Of The Protective Field - Siemens SIMATIC FS400 Anleitung

In the DoubleScan mode (H = 2) the response time is 8 ms. The safety distance is
therefore calculated again:
T = 8 + 250
C = 850 mm
S = 1600 x 0.286 + 850
The lower increase in the required 5 mm safety distance is caused by a greater
interference immunity.
WARNING
With access and perimeter guarding, it must be ensured that the start/restart interlock
function is active and that unlocking from inside the danger area is not possible.

6.1.4 Switching position at the end of the protective field

While the switching position of the first beam (synchronization beam) is positioned just
next to the display panel, the switching position at the end of the protective field
depends on the resolution and the protective field height of the light curtain (see,
Chapter 12.2.1).
WARNING
The determination of the position of the switching point is important in all cases of rear
area protection, e.g. in host/guest applications and/or with danger point guarding with
parallel approach to the protective field.
