Technical Specifications - BFT ICARO Instrucciones De Uso Y De Instalacion

2) GENERAL OUTLINE
The ICARO actuator offers ample installation versatility, thanks to the extremely
low position of the pinion, the compactness of the actuator and to the height
and depth which can be very easily adjusted. It is equipped with an antisquash
electronic device, which ensures utmost safety. The emergency manual release
can be activated very easily by means of a knob featuring a personalised key.
The gate stop is controlled by electromechanical end-of-stroke microswitches
or, for very cold areas, by proximity sensors.
The control board can be built-in or installed onto a separate cabinet.
The gearmotor (fig. 1) is made up of the following:
M Motor
R
Worm screw - worm wheel reduction gear
S
Electromechanical end-of-stroke unit or proximity sensor
P Pinion with release
C Control board with capacitor
E Obstacle detection device (Encoder)

4) PRELIMINARY CHECKS
Before proceeding to any installation work, check that the gate structure conforms
to whatever is prescribed by the current standards, and in particular that:
• The gate sliding track is linear and horizontal, and the wheels are suitable for
supporting the gate weight.
• The gate manual operation can be carried out smoothly along its entire run,
and there is no excessive side slipping.
• A correct play is provided between the upper guide and the gate to ensure
regular noiseless movement.
• The opening and closing gate stops are positioned.
• The established position for gearmotor fixing allows the emergency manoeuvre
to be carried out smoothly and safely. In the case where the elements checked
do not meet the above requirements, proceed to carrying out the necessary
corrective actions or replacements.
WARNING: Remember that control devices are intended to facilitate gate
operation, but can not solve problems due to any defects or deficiency result-
ing from failure to carry out correct installation or maintenance.
Take the product out of its packing and inspect it for damage. Should it be dam-
aged, contact your dealer. Remember to dispose of its components (cardboard,
polystyrene, nylon, etc.) according to the current prescriptions.
5) BASE PLATE ANCHORING
5.1) Standard position
• Dig a hole where the cement pad with the buried base plate log bolts is to be
placed in order to fix the reduction gear unit (fig.3). If the sliding track is already
there, digging must be partly carried out in the track foundation casting. This
way, should the track foundation casting sag, the gearmotor base would also
lower, thus maintaining the play between pinion and rack (approximately 1-2
mm).
• Position the base plate according to the dimensions specified in fig.4.
• The pinion symbol printed on the base plate must be visible and directed
towards the gate. This also ensures the correct positioning of the raceways
for electrical connections.
• Let the flexible pipes containing electrical cables protrude from the base
plate.
• In order to keep the base plate in its correct position during installation, it may
be useful to weld two iron flat bars under the track, and then weld the log bolts
onto them (fig.3).
• Make a concrete casting in such a way as to embody the base plate casting
into that of the gate track.
• Accurately check that:
The positioning dimensions are correct.
That the base plate is well levelled.
That the 4 stud threads are well clear of cement.
Let the casting harden.
5.2) Other positions
The gearmotor can be positioned in different ways. In the case where the gearmotor
is not fixed on the level of the sliding track (Standard position), you must ensure
that the gearmotor is tightly secured also in relation to the gate position, so as
to maintain a correct play (1-2mm) between rack and pinion. The current safety

standards with respect to persons, animals and things must be strictly observed,
and in particular risks of accidents due to squashing in the area of pinion-rack
meshing, as well as other mechanical risks, must be carefully avoided. All the
critical spots must be protected by safety devices in compliance with the
current prescriptions.
6) GEARMOTOR FIXING
When the casting has hardened, observe fig. 6 and proceed as follows:
• Position an M10 nut on each of the tie rods, keeping a distance of at least 25mm
• Position a plate "P" supplied as standard on each pair of tie rods and, with the
• Remove the cover and screw-cover guard from the gearmotor, and position
• Position the two upper plates P (Fig.6) and tighten the four locking nuts of the

7) RACK FITTING
A rack having a 4 tooth pitch must be fitted to the gate. As far as the length is
concerned, this must include the passage space, as well as the space for securing

the brackets activating the limit microswitches, and for the pinion meshing section.
There are different types of rack, each one differing in terms of capacity and gate
fixing method. The Company markets three types of racks, which are.
7.1) Mod. CFZ (Fig.7).
Galvanised iron rack - 22x22mm section - supplied in 2 - metre lengths - capacity
over 2000kg (≈ 20000N). First weld these pieces onto an adequate iron angle bar
and then weld the lot to the gate. Besides maintaining the distance between the
rack and the side of the gate, the angle bar makes it easy to fix the rack to the
gate, even when the latter is subject to slight side slipping. When join welding
the various rack pieces, you are advised to arrange a section of rack as in (fig.8)
to ensure a correct pitch along the entire length of the rack.
7.2) Mod. CPZ (Fig.7).
Plastic rack - 22x22mm section - supplied in 1- metre lengths - max. capacity
500kg (≈ 5000N). This model is to be fixed to the gate by means of normal or
self-threaeSng screws. Also in this case, you are advised to insert a section of rack
the other way round in the joint between the various pieces, so as to maintain the
correct tooth pitch. This type of rack is quieter and allows height adjustments to
be made even after having been fixed, using the slots provided.
7.3) Mod. CVZ (Fig.7)
Galvanised iron rack - 30x12mm section - supplied in 1 - metre lengths - threaded
spacers to be welded - max. capacity 2000kg (≈ 20000N). Having fixed the spacers
in the middle of each of the slots in the various rack pieces, weld the spacers to
the gate. Also in this case, arrange a section of rack the other way round in the
joining points of the various rack pieces to ensure a correct tooth pitch. The screws
which fix the rack to the spacers allow the rack to be adjusted in height.
7.4) Rack fitting
To fit the rack, proceed as follows:
• Activate the emergency release by rotating the appropriate release knob (See
• Rest the rack end on the control pinion and secure it (by welding or using
• In the case of incorrect gate alignment (excessive side curving) which cannot
DANGER - The welding operation is to be carried out by a competent person
who must be provided with all the personal protection equipment required
by the current safety standards.
8) PINION ADJUSTMENT
Having finished fixing the rack, the rack-pinion play needs to be adjusted to ap-
proximately 2mm (fig.6): this is obtained by slackening the four M10 nuts under
the gearmotor base by approximately 2mm, and then securing the four upper
nuts. Make sure that the rack and pinion are aligned and centred (fig.10).
WARNING - Remember that the rack and pinion life strictly depends on their
correct meshing.
9) ELECTROMECHANICAL LIMITING DEVICES
The operation must be carried out with the emergency release activated and
the mains power supply disconnected. The runners which control the limiting
devices are to be positioned at both ends of the rack.
- Push the gate fully open by hand.
- Position the opening end-of-stroke runner (fig.11) so that it intercepts the
- Push the gate fully closed by hand.
- Position the closing end-of-stroke runner (fig.11) so that it intercepts the

pleted, or for subsequent adjustments of the play between pinion and rack.

in such a way as to leave a clearance of approximately 50mm between the gate
