SICK scanGrid2 I/O User Manual

A distinction is made between the following field types, depending on the application
t
ype:
•
Protective field
•
Warning field
The distance to the nearest object is detected and compared with the distance specifi‐
cations of the configured protective or warning field. If the protective or warning field
has been interrupted, the corresponding signal is output.

Description The protective field protects the
hazardous area. If the sensor
detects an object in the protec‐
tive field, the safety outputs
switch to the OFF state.
Downstream control elements
can use this signal to end the
dangerous state, for example, to
stop the machine or vehicle
The warning field monitors
larger areas than the protective
field. Simple switching functions
can be triggered with the warn‐
ing field, e.g. a warning light or
an acoustic signal can be trig‐
gered if a person approaches,
even before the person enters
the protective field.

3.4 Example applications
Mobile hazardous area protection
Mobile
hazardous area protection is suitable for AGVs (automated guided vehicles) and
is used to prevent the vehicle from colliding with persons or objects.
The safe multibeam scanner monitors the area in the viewing direction and stops the
vehicle as soon as a person or object is located in the protective field.
