5.4.8.1 Additions and Minimum Depth of Detection Zone
The sum of the system-specific and application-specific detection zone additions (see
Chapter 5.3.5) is calculated according to the following formula:
Z
TOT
= Z
SM
+ Z
REFL
+ Z
AU
Z
TOT
= Sum of the system-specific and application-specific detection zone
additions, in mm
Z
SM
= Scanner measurement error, in mm
Z
REFL
= Addition of the reflectors taken into account, in mm
Z
AU
= Addition for application-specific undercut, in mm
The depth of the detection zone, with reference to the direct distance between the
danger zone and the detection point or line, is calculated according to the following
formula:
S
T
= (K x (T
SCAN
+ T
MACH
+ ( T
LAG
x L
LAG
))) + C + Z
TOT
S
T
= Depth of detection zone, distance from danger area to detection point or
line, including system and application-specific additions, in mm
K = Approach speed of a person or a person’s body parts
(1600 mm/s), in mm/s
T
SCAN
= Response time of the scanner, in s
T
MACH
= Response time of the machine or system, in s
T
LAG
= Lag time of the entire system, in s
L
LAG
= Factor for increase in lag time
C = Safety-related constant, in mm

= Largest width of the detection zone between the axis of the rotating mirror
and the outer edge of the detection zone, in mm
G

= Largest width of the danger zone between the axis of the rotating mirror
and the boundary of the danger zone, in mm
S = Safety distance, minimum distance from the danger zone to the point of
detection, to the plane of detection, or to the detection zone, in mm
