5.2 Mounting notes
Special notes on mounting a SOLID-2 Safety Light Curtain for safeguarding danger
points (
see Fig. 5.1-1):
✟ Calculate the safety distance according to the formula in Chapter 5.1.1.
✟ Ensure that it is impossible to reach under, over, around or walk behind the protective
field.
✟ Observe the maximum distance between machine table and protective field of 75 mm,
with reference to a table height of 750 mm. If this is not possible because the safety
distance is too big, e.g. a mechanical barrier must be provided.
✟ Observe the minimum required distance to reflective surfaces.
Special notes on mounting a SOLID-2 Safety Light Curtain for safeguarding danger areas
(
see Fig. 5.1-2):
✟ Calculate the safety distance according to the formula in Chapter 5.1.2.
✟ The resolution determines the minimum height of the protective field above the floor.
The calculation formula can also be found in Chapter
5.1.2.
✟ Ensure that the maximum height of the protective field above the reference plane of
1000 mm is not exceeded and only heights equal to or less than 300 mm are
considered impossible for an adult to crawl under (also see EN 999).
✟ It must not be possible to step into the danger area from the sides. Suitable hard guards
must be provided.
✟ Consider the position of the last light beam before the machine. It must not be possible
to stand undetected between this light beam and the machine.
Special notes on mounting a SOLID-2 Safety Light Curtain for access guarding (see
Fig. 5.1-3):
✟ Calculate the safety distance according to the formula in Chapter 5.1.3.
✟ The highest and the lowest light beam and thus the height of the protective field for
Safety Light Curtains with a resolution of 20, 30 or 40
mm is determined from the
requirements described in EN
ISO 13857.
✟ Access guarding systems must only be operated with start/restart interlock. Activate the
start/restart interlock internal or of a downstream safety interface and
check to make
sure it is working.
✟ Ensure while installing the start/restart button, that it must only be impossible to press
this button from the inside the danger zone. Make sure, that from the location of the
button there is a complete overview over the danger zone.
