Intended use
The Festo Checkbox Compact®has been designed for use
under normal operating conditions in closed rooms in indus
trial installations.
The Checkbox documented in this description is intended
exclusively for use as follows: Contactless checking of the
position and quality of small parts e.g. screws, springs, bolts,
which pass through on a conveyor belt.
Use the Checkbox only as follows:
– As intended in an industrial environment
– In perfect technical condition
– In its original state without unauthorised modifications.
Only the conversions or modifications described in the
documentation supplied with the product are permitted.
The guarantee will become invalid if the Checkbox is
opened.
The maximum values specified for pressures, temperatures,
electrical connections etc. must not be exceeded.
Please observe the standards specified in the relevant
chapters and comply with the regulations of the trade associ
ation and the German Technical Control Board (TÜV), the VDE
conditions as well as the relevant national regulations.

Light beam
With regard to the blue light hazard, the Checkbox Com
pact exceeds the limit values of the free group in ac
cordance with DIN EN 62471:2009-03. Therefore, an assi
gnment to risk group 1 applies for the blue light hazard.
Looking at the light source for a long or prolonged period
can dazzle your eyes and cause irritation.
Take measures to prevent eye exposure:
Do not remove any housing parts.
Only mount/remove the prism support when the power
supply is switched off.
Also take measures to ensure that if the light beam is
reflected off mirrored or reflective objects, it does not
pose a hazard (for example, by providing screening).
Do not look directly into the light beam and do not direct
the beam into the eyes of other people.
Ordinary light sources are divergent, i.e. the illuminated area
becomes larger as the distance from the light source in
creases. As a result, the risk of eye injury decreases as the
distance from the light source increases. However, as the
Checkbox Compact uses parallel light, the risk of eye injury is
not reduced as the distance increases; this applies to both
looking directly at the beam and looking into the beam via a
reflective surface.
