INSTALLATION
Overall dimensions of the gear motor expressed in mm.
POSITIONING OF THE FOUNDATION PLATE
It is very important to keep to dimension X shown in Fig.2. This value de-
pends 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 foundation 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 actuator 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 posi-
tioned 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 insert-
ing the R.
Apply the two screw covers C.
If the rack is already installed in a position which is higher than the pinion,
the plate can be raised (20 m maximum) by moving the nuts and the wash-
ers under the plate, as shown in Fig.10.
If the connecting cables already present make it difficult to fix the standard
plate, the optional plate BULL P3 (Fig. 11) can be used, thus allowing to
raise the actuator installation by about 34 mm and facilitating the passage
of cables.
POSITIONING OF THE LIMIT SWITCH BRACKETS
Manually open the gate and leave a clearance from 1 to 3cm according to
the weight of the gate between the main door and the mechanical stopper
A. Fix the bracket to the limit switch S by using the grains G, so that the limit
switch microswitch F is pressed. The same operation should be repeated
with gate in the closing phase.
N.B.: The limit switch bracket should be positioned so that the gate can be
stopped without hitting the mechanical stopper.

MANUAL OPERATION
Should a power failure or malfunction occurs, to manually operate the
gate proceed as follows:
- After inserting the customised key C, turn it anti-clockwise and pull
the lever L.
- The gear motor is unlocked and the gate can be moved by hand.
- To return to the normal operating mode, close the lever L again and
manually activate the gate until it is geared.5.4)
HOW TO INSTALL THE MAGNETS
(BULL424 SW.S ) FIG.14
The magnets are housed in special supports (fig.14-"A"). These magnets are
to be fitted to the limit switch brackets or the rack and cause the triggering
of sensors when they approach them.
Fitting onto the limit switch brackets
The bases are complete with hooking tongue allowing the fitting of the
magnets to the limit switch bracket supplied with the operator, as shown
in Fig.14-B.
This type of fitting allows to rapidly adjust the position of magnets. After
calculating the correct distance, fix the support in the correct position by
means of a screw, so as to avert the moving of the bracket.
Fitting onto the rack
As an alternative, the supports can be fitted directly to the rack, by
using the slots shown in Fig. 14-C. This fitting mode does not allow for
subsequent regulations. It is therefore advised to make some trials with
temporarily fitted supports before carrying out the final fitting.
IMPORTANT: The correct distance of the magnet with respect to the
sensor depends on the installation characteristics. This space cannot be
preset and must be adjusted on a trial basis.
The distances regarding the triggering of the sensor (value X) with respect
to distance K of 3 and 35 mm, which are shown in Fig. 14 are only indicative.
In any case, distance K must not exceed 35 mm as a higher distance will
not allow the triggering of the magnetic sensor.
BUFFER BATTERIES
An optional kit of buffer batteries is available. This permits the operation of
the system also in case of power failure.
The batteries can be installed inside the gear motor as shown in Fig.15.
The support of the control unit has a hole "Fig.15 ref. "A" which facilitates
passage of the battery cables.
For further information, please see instructions supplied with the product.
WIRE DIAGRAM
For the wire connections of the system and to adjust the operating modes,
please refer to the Instruction Manual of the control unit.
In particular, the anti-crash device (encoder) should be adjusted ac-
cording to regulations in force.
Please remember that the device should be earthed by means of the
appropriate terminal.
Fig.16 shows wiring for a standard installation. Before proceeding to wir-
ing, check that the type of cables used is consistent with those required
for accessories.
Dimension H stands for the installation height of photocells. A clearance
between 40 and 60 cm is advisable.
