Safety Light Curtain SLCS
Installation
5.2
Mounting
Various brackets are available for securing the safety light curtain (see chapter
9.8).
Mounting
1. Align the transmitter and receiver so that they are parallel with one another and
at the same height.
2. Align the transmitters and receivers parallel with one another.
3. The function reserve indicator helps with correct alignment.
When installing the safety light curtain in a danger zone, a minimum distance must
be maintained between the protection field and the danger zone. This distance
will guarantee that movements that pose a danger to a person can be brought to a
stop before that person comes in contact with the source of danger.
The distance is calculated from the lag time of the machine, the response time of
the safety light curtain and the speed of movement of the person entering the
hazardous area (EN ISO 13855, EN ISO 13857).
Vertical approach
Figure 5.2
Where K = 2000 mm/s and C = 0 mm, e.g., for SLCS14...
or C = 128 mm, e.g., for SLCS30...
the calculation formula for a distance S of 105 mm up to and including 500 mm is:
S = 2000 mm/s * (t
Note!
If S is greater than 500 mm, then K = 1600 mm/s must be used for calculations:
S = 1600 mm/s * (t
S must be at least 500 mm. Lower results must be corrected to a minimum
distance of 500 mm.
