GENERAL INFORMATION

This automatic system, with 24VDC single-phase power sup-
ply for sliding gates, is available in the following versions:
BULL 424 for gates with maximum weight equal to 350kg
BULL 624 for gates with maximum weight equal to 600kg
BULL is a monobloc system featuring a refined design and
reduced dimensions. The motor and an irreversible reduction
system, manufactured with high resistant materials, are hou-
sed in an aluminium container. BULL is equipped with spring
limit switches. The customised key emergency release allows
to open and close the gate in case of power failure.
Anti-crash safety is ensured by an electronic device (enco-
der and amperometric sensor) which detects any obstacle
present.

PRELIMINARY CHECKS

For a good operation of the automatic system for sliding
gates, the gate or door shall meet the following features:
- the track and relevant wheels must feature correct sizes
and must undergo adequate maintenance (in order to avert
excessive friction during the sliding of the gate).
- during operation, the door shall not excessively oscillate.
- a mechanical stopper (according to regulations in force)
shall limit the opening and closing movements.

FIG.1
POSITIONING OF THE FOUNDATION PLATE
FIG.2-3-4-5
It is very important to keep to dimension X shown in Fig.2.
This value depends on the type of rack used:
X = 52 mm for rack in nylon
X = 49 mm for rack in iron, 12x30mm
Preset a corrugated tube (Fig.2 -A) for the passage of power
supply cables and connection wires for the accessories.
Check that, at the end of the fitting, the foundation plate is
perfectly parallel with respect to the wing.
Fit the system with screw anchors on the bottom of the
cement (Fig.3).
Drill 4 holes, diam.10mm, by using the foundation plate as
drilling template.
Tightly anchor the foundation plate to ground through the
4 "T" steel screw anchors and the 4 "B" threaded bars,
M8x150mm and corresponding "D" nuts and "R" washers.
Alternative fitting systems are available on the market, e.g.
anchoring with retaining expansion band (Fig.3 -T2) to be
inserted in the hole with some hammer strokes.
Fitting to be cemented (Fig.4)
In this case, after providing an adequate foundation hole,
bend the threaded bars as shown in Fig.4.
Submerse the bars in cement, paying attention to the level
of the plate.
Wait that the cement hardens.
Fig. 5 shows the completed fitting plate.
Regardless of the type of fitting, check that the threaded
bars are firmly anchored to ground and that they protrude
for at least 24mm (44 mm for raised installation).
FITTING OF THE RACK
Rack in nylon (Fig.6).
Position the rack at a height of 68 mm from the centre line of
the fixing slot provided on the base on which the foundation
plate will be fitted. At that height, drill a hole on the gate and
provide for a M6 threading.
Keep to the P tooth pitch, even from a section of rack and
another. To this purpose, it could be useful to join another
section of rack (Part. C)
Rack in Fe 12x30mm (Fig.7).
Position the spacers D by welding them or fitting them with
screws to the gate, at 103 mm height from the centre line
of the fixing slot provided on the base on which the founda-
tion plate will be fitted. Fix the rack by following points 4.3
and 4.4.
Keep to the P tooth pitch, for all sections of the rack. To
this purpose, it could be useful to connect another section
of rack (Part. C)
Then fix the rack with V screws, taking care, once the actua-
tor is installed, that 1-mm backlash is left between the rack
and the tow wheel (seei Fig.8). To this purpose, use the slots
on the rack.
POSITIONING AND ANCHORING OF THE ACTUATOR
Position the gear motor on the foundation plate with the gear
centred with respect to the rack.
Release the automatic system and check that the gear be
correctly positioned along the entire stroke of the rack. If
required, adjust the alignment by using the special slots.
Fix the gear motor to the base by firmly tightening the 4 nuts
D and inserting the R.
Apply the two screw covers C.
