Important information
WARNING
Persons or parts of the body to be protected may not be recognized or not recognized in
time in case of non-observance.
Someone may already be in the protective field at the time of switchover. Only by switch‐
ing in the correct time frame, i.e., before the hazard occurs at this point for the person,
is protection provided (
see "Timing for monitoring case switching", page 34
b
Make sure that the control – using static control inputs – provides switching
between the monitoring cases in the correct time frame.
NOTE
The control for the monitoring case switching must meet the required safety level.
The circuit for the control inputs must be suitable for the ambient conditions to be
expected so that systematic and design-related effects and resulting errors on the
switching of the monitoring cases can be excluded.
Static complementary sampling
Using the two control input pairs on the S300 Advanced, 2
2
= 4 monitoring cases can
be switched.
Using the three control input pairs on the S300 Professional, 2
3
= 8 monitoring cases
can be switched.
Using the three control input pairs on the S300 Expert, 2
3
= 8 monitoring cases can be
switched.
Using external inputs (e.g., those of a Flexi Soft safety controller), 2
5
= 32 monitoring
cases can be switched via a maximum of five control input pairs.
