Important information
DANGER
Hazard due to lack of effectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
1.
Calculate the required minimum distance for your machine using the following
formulas and examples.
2.
Take this calculation and the specifications in these instructions into account
when mounting the safety laser scanner.
3.
Take this calculation and the specifications in these instructions into account
when configuring the safety laser scanner.
DANGER
Hazard 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.
Body parts to be protected may not be detected under coarse resolution.
b
Use a resolution of 70 mm or finer for hazardous area protection.
b
For hazardous area protection with a resolution of 70 mm: make sure that it is
possible to detect a human leg.
b
For hazardous area protection with a resolution of 70 mm: mount the safety laser
scanner at a height of at least 300 mm (height of the scan plane).
b
If it is not possible to mount the safety laser scanner at a height of at least
300 mm, use a finer resolution
see "Calculating required resolution", page 41
4.4.5.2
Calculating minimum distance
Overview
The calculation of the minimum distance is based on international or national stand‐
ards and statutory requirements applicable at the place of installation of the machine.
If the minimum distance is calculated according to ISO 13855, then it depends on the
following points:
•
Machine stopping time (time interval between triggering the sensor function and
the end of the machine’s dangerous state)
•
Response time of the protective device,
see "Response times", page 137
•
Reach or approach speed of the person
•
Resolution (detection capability) of the safety laser scanner
•
Type of approach: parallel
•
Parameters specified based on the application
•
Supplements for general and, possibly, reflection-based measurement errors
•
Supplement to protect against reaching over
•
Height of the scan plane
•
Switching time between monitoring cases
