6.3 Vertical installation of the safety light curtains
6.3.1 Safety light curtains resolution 14 mm
These designs are suitable for access prevention of fingers (finger
protection)�
The minimum safety distance (S) is determined using the
following formula:
S = 2000 (t
1
+ t
2
) + 8 (d - 14)
This formula applies to minimum safety distances (S)
between 100 and 500 mm�
The min� safety distance (S) must be > 100 mm�
A = hazardous area
H = height
S = min� safety distance
G = reference level
If due to the special configuration of the machine it should be possible to reach
the hazardous area from above, the highest light beam of the safety light curtain
should be at a height (H) (measured from the reference level (G)) whose value is
determined to the specifications in ISO 13855�
