Advancement for the monitoring case switching of a
connected S3000
The following information only applies for applications in which you operate an S3000
safety laser scanner on the SDL connection on the UE4155.
If the S3000 switches between several monitoring cases, then you must advance the
timing for the switching.
Define the timing for the switching such that the S3000 already detects a person in the
protective field before the dangerous state occurs!
Note that at the time of the switching there may be a person in the protective field. Only by
means of switching in the correct time frame (i.e.
before
the hazard occurs at this point for
the person) is protection provided.
If you operate the control inputs for switching the S3000 using the bus node, then you
must advance the timing for the switching by 0.5 times the basic response time of the
S3000.
If you have configured an input delay for the control inputs on the S3000, then you
must also advance the timing for the switching by the input delay configured.
