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.
E
MERGENCY RELEASE
To be undertaken after disconnecting power supply.
The operator is irreversible and keeps the door closed even without a lockset.
To open the gate manually, in open the motor cover and turn the knob «A» anti-clockwise.
To restore electric working you have to turn the lever clockwise (Fig. 7).
L
IMIT SWITCH ADJUSTMENT
To adjust the assembly: release nuts G, after establishing the direction of movement of
cam H for opening and closing, position the two limit switches, F, by turning knobs P and
judging by sight.
After checking for correct operation of the two microswitches, precisely adjust their
positions so that the gate will stop in the desired position during opening and closing. Then
fasten nuts G.
N.B. The standard limit switch is used for gates up to 10,5 meters long.
A
DJUSTMENT OF THE SAFETY CLUTCH (Fig. 9)
N.B.: These operations must be executed only after the power supply has been
suspended.
To adjust, lock the motor shaft (A) with a n° 15 hex unrech, unscrew the locking nut (B)
with a n° 19 wrench.
To increase thrust force, tighten the grub screw, C, with a n° 6 hex wrench.
Let the gate move electrically a number of times, holding it with your hands so that the
thrust force is slightly higher than that actually required to move the gate (UNI 8612
REGULATIONS).
When adjustment has been completed, remember to fasten the nut at the motor shaft.
M
AINTENANCE
