SICK microScan3 Core I/O AIDA User Manual

4.3.8 Mobile hazardous area protection
The safety laser scanner is mounted with a horizontal scan plane in a mobile applica‐
tion, f
or example on an automated guided vehicle. In mobile hazardous area protection,
the safety laser scanner protects the hazardous area created by the vehicle’s move‐
ment. The safety laser scanner detects a person’s legs. The protective field is parallel to
the direction of approach.

DANGER
Ha
zard 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 minimum dimensions required for the protective field taking into
account the supplements described in the following text along with the specific
requirements imposed by your application.
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.
NOTE
•
In a mobile applic
a
tion, a resolution of 70 mm (leg detection) is sufficient for
detecting people. By contrast with stationary hazardous point protection, this is
also true for a low mounting height, as the safety laser scanner moves together
with the vehicle.
•
In the following calculation examples, only the vehicle speed is taken into account,
not the speed of a walking person. This is based on the assumption that the
person recognizes the danger and stands still.
4.3.8.1 Protective field length
The protective field must be designed so that it detects a person at a minimum
dist
ance from the hazardous point. This distance is required to ensure that the vehicle
comes to a stop before it reaches a person or an object.
