5.2 Access guarding
Safety sensors with up to 90 mm resolution are used for access guarding into danger zones. They detect
people only upon entry into the danger zone, i.e., they do not detect parts of a person or whether a person
is present in the danger zone.

5.2.1 Muting
Access guarding can be operated with a bridging function for material transport through the protective field.
In this case, the integrated muting function is used, see chapter 4.8 „Timing controlled muting“
Objects brought into the protective field must take up the entire field width so that it cannot be
accessed next to the object. Otherwise locks are to be provided to prevent access.
WARNING
Risk of injury due to inadmissible application of blanking!
Blanking is not permitted with danger zone guarding since the blanked areas would form accessible
bridges to the danger zone.
Do not use blanking for danger zone guarding.
