Installation
This section contains important information on installing the SOLID-4. The SOLID-4's
protective function is only guaranteed if the following installation specifications are
observed. These installation specifications are based on the respective applicable versions
of European standards, such as EN 999 and EN ISO 13857. If a SOLID-4 is used in
countries outside of the EU, the valid requirements in those countries must also be
observed.
Installation is dependent on the type of protection as described in Chapter „Safety“.
Because of this, the situations of:
• Point of operation guarding
• Danger zone guarding
• Access guarding
are considered separately below. The applicable distance from the protective device to
reflective surfaces in the surrounding area is presented for all types of protection based on
these situations.
6.1
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.
6.1.1
Safety distance for point of operation guarding
Calculation of the safety distance for a SOLID-4 Safety Light Curtain with resolution of 14,
20, 30 or 40 mm for point of operation guarding:
The safety distance "S" for point of operation guarding is calculated in accordance with EN
999 with the formula:
S [mm] = K [mm/s] x T [s] + C [mm]
