LECTrIC sAfETY DEVICEs
for a sliding gate weighing more than 300 kg it is obligatory to fit 2 pairs of
photocells and mobile sensors in such a way as to protect any potentially
dangerous openings in the gate (fig. 6). The photocells must be located
at a height of between 40 cm and 60 cm. One pair of photocells must be
located inside the premises and adjusted so that they cover the entire
travel distance of the gate, while the other pair must be located externally
between the gateposts. in order to avoid the risk of personal injury the
gate and the railings must be covered with fine metal mesh for a distance
along the railings such as to cover the full travel distance of the gate) and
in any event there must be no openings of sufficient size to introduce a
hand. Any other shear points or entanglement/crushing points must be
protected or covered (see mechanical safety strip) (EN 12453 norm).
gate movement can be signalled by a flasher unit installed nearby.
Use S1/R2 electronic control board.
for connections and technical data of accessories refer to the appropriate
booklets.
