SICK microScan3 Core I/O User Manual

Supplement Z
F
f
or lack of ground clearance
This supplement is necessary, because, generally, a person is detected above the foot
and so the braking process cannot take account of the length of the foot in front of the
point of detection. A person’s foot could be injured if a vehicle has no ground clearance,
see "Supplement Z
F
for lack of ground clearance", page 47.
Calculation example for the protective field width S

S

+ 2 × (

where:
•
S
B
= protective field width in millimeters (mm)
•
F
B
= vehicle width in millimeters (mm)
•
TZ = tolerance range of the safety laser scanner, see "Data sheet", page 142
•
Z
R
= supplement for reflection-based measurement errors in millimeters (mm)
•
Z
F
= supplement for lack of ground clearance of the vehicle in millimeters (mm)
NOTE
In man
y cases, the safety laser scanner is mounted in the center of the vehicle. If this
is not the case, you must define the protective field asymmetrically. Make sure that the
supplements are located on the right and left of the vehicle.
5.3.9.3 Height of the scan plane
DANGER
H
azard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of
non-observance.
b
Mount the safety laser scanner so that the maximum scan plane height is
200 mm.
People who are lying down are reliably detected if the scan plane is at a height of no
more than 200 mm.
In many cases, a mounting height of 150 mm above the floor (height of the scan plane)
is suitable.
