5. Sensor position
Below is an example:
5.6 Installations on moving elements
5.6.1 Introduction
SBV-01 sensor can be mounted on moving vehicles or moving parts of the machinery.
The characteristics of the detection field and of the response time are the same as in static installations.
5.6.2 Speed limits
The detection is guaranteed only if the speed of the vehicle or of the part of machinery is from 0.1 m/s (0.66 ft/s)
to 1.6 m/s (5.25 ft/s).
Note
: only the speed of the vehicle or of the part of machinery is considered. This is based on the assumption that
the person recognizes the hazard and stands still.
5.6.3 Detection signal generation conditions
When the sensor is mounted on moving parts, it will detect static objects as moving objects.
The sensor will trigger a detection signal if the following conditions are met:
l
The RCS (Radar Cross-Section) of static objects is greater than or equal to the RCS of a human body
l
The relative speed between the objects and the sensor is greater than the minimum speed necessary for
detection.
5.6.4 Prevention of unexpected restart
As for static installations, when the moving part where the sensor is installed is arrested because of a detection,
the system will switch to restart prevention safety function and the sensor will detect the presence of static
people (for details, see "Cases of non-guaranteed function" on page 34). Static objects are then automatically
filtered out and no longer detected.
The restart of the moving vehicle or moving part of the machinery in the presence of static objects can be
prevented using the following methods:
l
Static object detection option enabled (see "Restart prevention function: static object detection option" on
page 34).
l
Anti-masking function: if the function is enabled, an error will occur when the static object will be close
enough to limit the detection of the sensor.
