Figure 19: Stationary application with horizontal scan plane for hazardous area protection
NOTE
Mark the outline of the protective field boundaries on the floor after you have worked
out the protective field size. By doing this, you allow machine operators to see the pro‐
tective field boundaries and make it easier to thoroughly check the protective function
at a later date.

Overview
The protective field must be designed so that it detects 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 protective
field size required.
If you define a number of monitoring cases with different protective fields, you must
calculate the protective field size separately for each protective field used.
In many cases, a resolution of 50 mm to 70 mm is suitable for hazardous area
protection.
