8.7 Timing of analysis case switching
When switching between analysis cases (field sets), it is possible that a person may
already be in the newly activated protective field when switching takes place. Only
timely switching (namely before the danger arises at this location) can ensure protec‐
tion.
WARNING
Risk of ineffectiveness of the protective device!
Persons and parts of the body to be protected may not be recognized in case of
non-observance.
•
Switching of the analysis case should be timed so that the device detects a person
in the protective field with a sufficient minimum distance before the dangerous
state occurs.
8.8 Hazardous area protection
The device is mounted with a horizontal scan plane in a stationary application, for
example on a machine where the hazardous area is not completely surrounded by a
physical guard. During hazardous area protection, the device detects a person’s legs.
The protective field is parallel to the person’s direction of approach.
