NOTE
• Using 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.

7.13.2 Monitoring case switching via speed information
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 39 ).
b
Make sure that the control – using dynamic control inputs (incremental encoders)
– provides switching between the monitoring cases in the correct time frame.
b
Make sure that only one safety laser scanner is connected to an incremental
encoder.
b
Use two incremental encoders so that a possible fault in one encoder can be
detected.
b
Lay the connecting cables to the incremental encoders separately.
Prerequisites
For dynamic sampling using incremental encoders, configure the following:
• The Use speed option
• For each monitoring case, the range of speeds for switching to the monitoring case
