Minimum Safety Distance Calculations for Vertical Applications
For vertical applications, the previously indicated formula for the minimum safety dis-
tance can be used, but further considerations must be taken into account.
S = (K*T) + C
Where:
S =
Minimum safety distance (mm)
K
= 1600 mm/s or 2000 mm/s (see Note)
T =
t
1
+ t
2
C = 8(d -14 mm) or 850 mm (see Note)
t
1
= Response time of the Laser Sentinel (s) (see "Response Time and Scan Cycle
Setting" on page 62
)
t
2
= Machine stopping time (s) (see machine specifications)
d = Detection capability of the ESPE (mm)
Note:
K = 2000 mm/s if the calculated value of S is ≤ 500 mm
K = 1600 mm/s if the calculated value of S is > 500 mm
C = 8(d -14) mm for devices with detection capability d ≤ 40 mm
C = 850 mm for devices with detection capability d > 40 mm
Body parts protection (reference contour)
When the safety laser scanner is used for body parts det
ection, in applications where
the approach angle exceeds ±30° to the detection plane, it shall monitor a physical
boundary. Reference boundary monitoring requires a comparison of the reference dis-
tance and the distance measured by the device.
The reference distance is the distance between the safety laser scanner and each point
of the boundar
y (e.g. a wall) configured at the first installation. The stated detection
capability shall be in the range from 30 mm to 70 mm. If the reference boundary is the
edge of the safeguarded aperture, the tolerance zone should not exceed half of the
stated detection capability (see also dimension a). Otherwise, it should be protected by
another means, such as fixed guarding.
