5 FUNCTIONING PRINCIPLES
NOTICE
The ability to detect an object depends on the RCS of the object. The static object
detection option does not guarantee 100% detection of static objects.
5.7.2
Availability
The static object detection option is available for:
l
control firmware version 1.5.0 or later, and
l
sensor firmware version 3.0 or later.
5.7.3
Possible applications
This option can be useful if the sensor is installed on moving elements (see
) or to prevent the restart of a robot that could bump
into a static object in the area temporarily.
5.7.4
Operation
The option can be enabled for each protective field of each sensor with the safety
working mode set to
Both (default)
or
Always restart prevention
. Enable the option
only if the protective field is free of static objects; otherwise, the system would never
reactivate the detection signals after a motion is detected in the area.
The option is active in the protective field area, defined by the angular coverage and
detection distance set.
5.7.5
Restart timeout parameter
With the static object detection option enabled, the
Restart timeout
parameter's
minimum value is 0.1 s.
WARNING
If the Restart timeout is set to a value less than 4 s, the sensor is no longer able to
detect breathing movement or the movements necessary for a person to remain in
balance in an upright or a squatting position. Set a value less than 4 s only for areas
where people have no access.
5.8
Features of the restart prevention function
5.8.1
Cases of non-guaranteed function
The function is not guaranteed in the following cases:
l
there are objects that limit or prevent the sensor from detecting motion.
l
the person is lying on the floor and the sensor is installed at a height below 2.5 m
(8.2 ft) or with an inclination lower than 60° downward.
l
the sensor does not detect a sufficient portion of the body, for example if it detects
the limbs but not the torso of a person sitting
[A]
, lying down
[B]
or leaning
[C]
.
