4.3.7.1 Protective field
In hazardous area protection, the minimum distance typically defines the protective
f
ield 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. Resolutions coarser than 70mm are not permitted.
