Calculation example: Application type 1
The example shows the calculation of the minimum distance for application type 1 (e.g.
object entry, people are ruled out on the transport level) when the reduced resolution is
deactivated.

Effective resolution with Smart Box Detection
If Smart Box Detection is configured on a single system and the protective field is
free of objects, the protective device has an effective resolution of 14 mm (reduced
resolution deactivated).
As soon as the protective device detects a valid object, the detection capability of the
free protective field area changes. The detection capability of the protective field area
not covered by an object depends on the configured reduced resolution.
NOTE
Configuration of reduced resolution is only permitted in the framework of application
type 1

Smart Box Detection Override
Overview
Smart Box Detection Override enables manual override of the protective device after an
invalid object has been detected by the protective device. The system can be released
or an error-free state can be achieved.
Smart Box Detection Override is always active if Smart Box Detection has been config‐
ured.

Object exit (regardless of whether people can be ruled out on the transport level) or object entry (people can be ruled out on the
