If there is a retroreflector in the protective field level (distance of the retroreflector from
protective field ≤ 6 m), it may not be possible detect people and parts of the body that
are to be protected, or it may not be possible to detect them on time.
b
Avoid retroreflectors in the protective field level if possible.
b
With retroreflectors at the protective field level: Increase overrun of the protective
field over the opening to be protected by supplement Z

Protective field
T
he protective field must be designed so that it detects access by a person at a
minimum distance from the hazardous point. This distance is required to prevent a
person or part of their body from reaching the hazardous area before the end of the
machine’s dangerous state.
In hazardous area protection, the minimum distance typically defines the position at
which the safety laser scanner is mounted.
In many cases, a resolution of 30 mm or 40 mm is suitable for hazardous point
protection.

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.

Persons or parts of the body to be protected may not be recognized or not recognized in
time in case of non-observance.
b
Always mount the safety laser scanner so that it is impossible to reach around or
behind.
b
Provide suitable additional measures if necessary.
NOTE
T
he required minimum distance depends on the safety laser scanner’s set resolution.
Take account of the following notes when choosing the resolution:
•
If you choose a fine resolution, the protective field range is smaller and so the
protective field is only suitable for smaller hazardous points. But the required
minimum distance is smaller, so you can mount the safety laser scanner closer to
the hazardous point.
•
If you choose a coarser resolution, the protective field range is larger and so
the protective field is also suitable for larger hazardous points. But the required
minimum distance is larger, so you must mount the safety laser scanner further
away from the hazardous point.
