Important information
WARNING
P
ersons 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 36).
b
Make sure that the control – using static control inputs – provides switching
between the monitoring cases in the correct time frame.
Static complementary sampling
F
rom these five pieces of input information A, B, C, D and E, 2
5
= 32 combinations can
be represented. You can therefore configure unique input conditions for 32 monitoring
cases.

NOTE
An unde
fined input information will result in the device switching the safety outputs to
the OFF state or signaling Protective field interrupted.
Static 1-of-n sampling
W
ith 1-of-n sampling, you use the single connections of the control input pairs.
NOTE
•
Usin
g external inputs (e.g., those of a Flexi Soft safety controller), a maximum of
ten input connections can be used.
•
All connections must be connected.
•
Once connection must be 1.
•
Only one connection is ever allowed to be 1.
