safety application)
Description The protective field is
the area in which the
test object specified
by the manufacturer is
detected by the elec‐
tro-sensitive protective
equipment (ESPE). As
soon as the electro-sen‐
sitive protective device
detects an object in
the protective field, it
switches the associated
safety outputs to the
OFF state. This signal
can be passed to con‐
trollers resulting in the
dangerous state com‐
ing to an end, e.g. to
stop the machine or the
vehicle.
The contour as refer‐
ence field monitors a
contour of the environ‐
ment. The safety laser
scanner switches all
safety outputs to the
OFF state if a con‐
tour does not match
the set parameters,
because, for example,
the mounting of the
safety laser scanner
has been changed.
The contour detection
field monitors a contour
of the environment. The
electro-sensitive protec‐
tive device switches
the associated safety
outputs to the OFF
state if a contour does
not correspond to the
set specifications, e.g.
because a door or flap
is open.
The warning field mon‐
itors larger areas than
the protective field.
Simple switching func‐
tions can be triggered
with the warning field,
e.g. a warning light
or an acoustic signal
can be triggered if
a person approaches,
even before the person
enters the protective
field.
3.4 Example applications
Hazardous area protection
In ha
zardous area protection, people are detected if they stay in a defined area.
This type of protective device is suitable for machines, where it is possible to see a
hazardous area completely from the reset pushbutton. When the hazardous area is
entered, a stop signal is triggered and starting is prevented.
