l there are objects that limit or prevent the sensor from detecting movement, particularly if the limitation
lasts longer than the delay time set (parameter Restart time out).
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 [B] or leaning [C].
WARNING! The position of the person is determined by the position of his or her center of
gravity. This function is not guaranteed if a person has body parts within the sensor's field of
vision but the axis of the person’s center of gravity is outside that field.
Only when there are no restrictions does the function ensure that a person is detected when standing up [D].
4.4.4 Types of managed restart
NOTICE: it is the responsibility of the machinery designer to assess if automatic restart prevention can guarantee the
same level of safety as manual restart (as defined in standard EN ISO 13849-1:2015, section 5.2.2).
The system manages three types of restart prevention:
Type Conditions for enabling machinery restart
Automatic The time interval set through the Inxpect Safety application has passed since the last
motion detection*.
Manual The status of the restart enable button indicates that the restart is enabled (digital
input status = 1).
