DANGER
Ineffectiveness 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.
The critical response time is exceeded if the basic response time is too high, possibly
due to multiple sampling or the use of external OSSDs.
b
For access protection, set the total response time of the safety laser scanner to no
greater than 90 ms.
Higher response times may be permitted in specific applications if agreed with the
responsible authority, e.g., if you increase the available detection time by mounting the
safety laser scanner at an angle.
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

Stationary vertical operation for hazardous point protection
Hazardous point protection is necessary if the operator must remain near the danger‐
ous state 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
Ineffectiveness 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
must use the contour of the surroundings as a reference for the safety laser scanner.

4.3.6.1
Minimum distance
Overview
For 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.
For hazardous point protection, you can operate the safety laser scanner using a
30 mm or 40 mm resolution. For each resolution, you can select between a 60 ms and
120 ms response time. Due to the proximity to the hazardous point, it is usually only
possible to use the shorter response time. The resolution and response time determine
the maximum protective field range and the minimum distance to the hazardous point.
