Installation
This section contains important information on installing the SOLID-2. The effects of its
effective protection are only guaranteed if the following installation requirements are
observed. These installation specifications are based on the respective applicable
versions of European standards such as EN 999 and EN ISO 13857. If SOLID-2 is used in
countries outside of the EU, the valid requirements in those countries must also be
observed. The installation depends greatly on the type of protection being provided.
Because of this, the situations of:
• Safeguarding danger points
• Safeguarding danger areas
• Access guarding
are considered separately below. The applicable distance from the protective device to
reflective surfaces in the surrounding area are presented for all types of protection based
on these situations.
5.1
Calculating minimum distances
Light curtains can only perform their protective function if they are mounted with a
sufficient safety distance. The calculation formulas for the safety distance depend on the
type of protection. In the harmonized European standard EN 999, “Positioning of
protective devices with regard to approach speed of parts of the human body“, the
installation situations and calculation formulas for safety distance are described for the
types of protection named above.
The formulas for the required distances to reflective surfaces are based on the European
standard for “Active opto-electronic protective devices“ prEN IEC 61496-2.
5.1.1
Safety distance for safeguarding danger points
Calculation of the safety distance for a SOLID-2 Safety Light Curtain with resolution of 20,
30 or 40 mm to safeguard danger points:
The safety distance S for safeguarding danger points is derived in accordance with EN
999 from the formula:
S [mm] = K [mm/s] x T [s] + C [mm]
