7.4.4 Formula for mobile application
To calculate the depth of the dangerous area (S) for mobile applications, use the following formula:
Where:
Variable Description Value
Measurement
unit
K Maximum vehicle/part of
machinery speed *.
For detection distance ≤ 4 m (13.12 ft):K ≤
3000
For detection distance > 4 m (13.12 ft): K ≤
2000
mm/s
T Total system stopping time
(Inxpect SRE 200 Series +
machinery)
0.1 + Machinery stopping time (calculated in
accordance with standard ISO 13855:2010)
s
C Corrective value 200 mm
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.
Note: when using Fieldbus, add the communication and processing time required for the signal to reach the
machine after the safety output is activated.
