f the dangerous state is produced by a vehicle (e.g. AGV or fork lift), the hazardous area
that is produced by the movement of the vehicle is protected by the S3000.
 The S3000 may only be used to protect vehicles powered by electric motor.

Due to the movement of the S3000 itself in a mobile application, a resolution of 70 mm
is sufficient for the detection of people.
 In the following calculations only take into account the velocity of the vehicle, not the
speed of the person walking. This is based on the assumption that the person will
recognize the danger and stand still.
 If the application is to protect vehicles from collisions, then you may need to use
different assumptions. These are very specific and can therefore not be described here.
Contact the relevant authorities and clarify the assumptions that must be taken into
account with regard to your application.
For a horizontally mounted mobile application, determine:
 protective field length
 protective field width
 height of the scan plane
 restart behavior
 methods of preventing unprotected areas
5.4.1 Protective field length
You must configure the protective field such that a minimum distance to the vehicle is
maintained. This ensures that a vehicle monitored by the S3000 comes to a stop before a
person or object is reached.
If you define several monitoring cases with different protective fields, particularly if you
switch between monitoring cases dependent on velocity, you must calculate the protective
field lengths for all protective fields used.
How to calculate the protective field length S

(see EN ISO 13855):
 Calculate the necessary protective field length using the formula:
