Installations on moving elements

6.6.1

Introduction

LBK 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.
6.6.2

Speed limits

The detection is guaranteed only if the speed of the vehicle or part of the machinery is from 0.1 m/s (0.66
ft/s) to 2 m/s (6.56 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.
6.6.3

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:
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
l
detection.
6.6.4

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 (if Safety working mode is not
Always-on access detection), and the sensor will detect the presence of a human body (see Cases of
non-guaranteed function on page 44). 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:
Static object detection option enabled (see Restart prevention function: static object detection option on
l
page 43).
