is cal‐
culated as follows:

RT
= 8 × (d - 14)
= 8 × (30 mm - 14)
= 128 mm
C
RO
depends on the height of the protective field of the primary protective device and
on the height of the hazardous area. The values must be determined by means of
ISO 13855, Chapter 6.5.1, Table 1.
NOTE
The primary protective device deTec4 Core is available in two variants with protective
field heights of 1,500 mm and 1,200 mm. The different values must be taken into
account in the calculation of the supplement for reaching over and reaching under.
The height of the protective field of the primary protective device deTec4 Core is
1,200 mm or 1,500 mm, depending on variant. The upper edge of the protective field
therefore depends on the mounting height of the primary protective device.

Minimum distance with deTem4 Core
If the primary protective device deTem4 Core is used in the safety system, the minimum
distance is calculated in accordance with the following formula:
S = K × T + C
S = K × (t
