SICK S300 Mini User Manual

where
•
S = Minimum dis
tance [mm]
•
T
M
= Stopping time of the machine or system
•
T
S
= Response time of the safety laser scanner
•
d = Resolution of the safety laser scanner [mm]
The reach or approach speed is already included in the formula.
•
If the result is S ≤ 500 mm, use the calculated value as the minimum distance.
•
If the result is S > 500 mm, you may be able to reduce the minimum distance
using the following calculation:
S = 1,600 × (TM + TS) + 8 × (d – 14) [mm]
•
If the new value is S > 500 mm, then use the newly calculated value as the mini‐
mum distance.
•
If the new value is S ≤ 500 mm, then use 500 mm as the minimum distance.
Response time T
S
of t
he safety laser scanner
The response time T
S
depends on the:
•
Basic response time of the safety laser scanner
•
Set multiple sampling
•
Transmission speed to external OSSDs via EFI

4.3.7 Mobile applications
If the dangerous state is produced by a vehicle (e.g., AGV or fork lift), the hazardous
ar
ea that is produced by the movement of the vehicle is protected by the safety laser
scanner.
NOTE
•
T
he device must only be used to protect vehicles that are powered by an electric
motor.
•
Because the safety laser scanner itself is moving in a mobile application, a resolu‐
tion of 70 mm is sufficient for detecting people.
•
In the following calculations, only the vehicle speed is taken into account and not
the speed of a walking person. This is based on the assumption that the person
recognizes the danger and stands still.
•
If the application is to protect vehicles from collisions, then it may be necessary to
use different assumptions.
For a horizontally mounted mobile application, you determine the following:
•
Pr
otective field length
•
Protective field width
•
Height of the scan plane
•
Restart behavior
•
Measures to prevent unsecured areas
4.3.7.1 Protective field length
Overview
Y
ou must configure the protective field so that a minimum distance to the vehicle is
upheld. This minimum distance ensures that a vehicle monitored by the safety laser
scanner stops before a person or an object is reached.
