ffectiveness of the protective device
If a critical response time is exceeded (for an object diameter of 150 mm and speed of
1.6 m/s: 90 ms), a person may not be detected under certain circumstances.
b
For access protection, set the total response time of the safety laser scanner to no
greater than 80 ms.
Higher response times may be permitted in specific applications if agreed with the
r
esponsible authority, e.g., if you increase the available detection time by mounting the
safety laser scanner at an angle.
The response time T
S
of the safety laser scanner depends on the:
•
Basic response time of the safety laser scanner
•
Set multiple sampling
•
Transmission speed to external OSSDs via EFI

4.3.6 Stationary vertical operation for hazardous point protection
Hazardous point protection is necessary if the operator must remain near the danger‐
ous s
tate of the machine. For hazardous point protection, it is necessary to be able to
detect hands. To provide hand protection, a resolution of 40 mm or finer is required.
DANGER
Ine
ffectiveness of the protective device
The device is not suitable for detecting fingers because the finest resolution available is
30 mm.
b
Do not use the device for safety applications that require the detection of fingers.
To protect the protective device against inadvertent adjustment or manipulation, you
mus
t use the contour of the surroundings as a reference for the safety laser scanner.

4.3.6.1 Minimum distance
Overview
F
or hazardous point protection, a minimum distance must be maintained between the
protective field and the hazardous point. This minimum distance ensures that the haz‐
ardous point can only be reached once the dangerous state of the machine has been
stopped completely.
