Emergency Release - BFT X 130 Instructions D'utilisation Et D'installation

ENGLISH
The operator reliability and safety is directly affected by the condition
of the roll-up door structure.
Motor drive only facilitates operation and does not solve the problems
caused by defective or deficient installation or failed maintenance of
the roll-up door.
7) FITTING THE OPERATOR
1) Arrange the gearmotor unit halfway along the spring-holder shaft, and
lightly fix it to bracket S (Fig. 2) using screws V and nuts D.
In the case of shafts with a 42 or 48mm diameters, fit the pairs of half
bearings CS, paying attention to the position of the hole which must
coincide with slot A (Fig. 2).
2) Drill a 10mm diameter hole through the roll-up door shaft, to correspond
with slot A.
3) Complete the fixing operation by inserting appropriate screw V into the
hole to prevent the gearmotor unit from rotating (Fig. 3).
4) Fix bracket S and complete screw tightening (Fig. 2).
5) Put the two sections of the drive pulley back together inside the roll-up
door opener unit, making sure that the bearings are correctly positioned
in the sliding channel and that the pulley toothing and the sliding channel
are free from any drilling residue, dirt etc.(Fig.4).
Grease the two parts of the driving pulley before connecting them.
6) Make a hole (Fig. 5 ref. F) in the top end of the roll-up door, then secure
the roll-up door to the drive pulley by means of screw V.
NOTE: Check that, when the roll-up door is fully lowered, the limit device
protection box can be easily accessed (Fig. 1 "F"). If necessary, rotate
the gearmotor unit while keeping the drive pulley still (in "EF" models
provided with electric brake, use the emergency release device).
8) ELECTRIC INSTALLATION SETUP
Provide electrical installation complying with the CEI standards actually in
force. The power supply connections must be kept totally separate from the
service connections (photocells, safety edges, control devices etc.).
WARNING! For the connection to the power supply, use a multipolar
cable having minimum 4x1.5 sq mm cross section and complying with
the previously mentioned regulations (for example, if the cable is not
protected it must be at least equal to H07 RN-F, whereas if it is protected
it must be at least equal to H05 VV-F with a 4x1.5 sq mm section).
Connect the control and safety devices in compliance with the standards
actually in force. Fig. 8 indicates the number of connections and the cross
section for power supply cables approximately 100 metre long; in case of
longer cables, calculate the cross section for the true operator load. When
the auxiliary connections are over 50-metre long or pass through critical
disturbance areas, it is recommended to decouple the control and safety
devices by means of suitable relays.
These are the main components for an operator (fig. 8):
I)
Type-approved omnipolar circuit breaker having adequate capacity,
with at least 3,5 mm contact opening, provided with protection against
overloads and short circuits, suitable for cutting out the operator from
the power supply mains. If not already present, a type-approved
omnipolar switch with a 0.0.3 A threshold should be installed in the
circuit before the operator.
QR) Control panel and incorporated receiver
S) Key selector
AL) Blinker with tuned antenna
M) Operator
CS)
Safety edge
CC) Edge control device
Ft, F) Pair of photocells
T)
1-2-4 channel transmitter.
Fig. 11 illustrates the connection diagrams referred to the various types of
installation (1 or 2 motors, with or without electric brake) fitted with a HOLD-
TO-RUN control device. Use an omnipolar commutator (10A-250V) with a
three-position button and direction arrows.
For other control devices, refer to the respective instruction manuals.
9) END-OF-STROKE ADJUSTMENT
WARNING: Disconnect the mains power supply before opening the limit
switch adjustment box cover.
CLOSING LIMIT SWITCH.
Move the roller shutter to the required closing position, disconnect the main
supply power and loosen the screw that fastens the cover. Manually adjust
the RC wheel (fig.6) until the triggering of the MC closing microswitch is
heard.
OPENING LIMIT SWITCH
Place the F reference ring onto the C microswitch support and close the
C limit switch box cover. Re-connect the machine to the mains power sup-

ply. Open the roller shutter electrically and stop it at the required opening
height, then re-close the roller shutter. At this stage, disconnect the mains
power supply and loosen the screw that fastens the cover. Align the RA
stopping wheel with the ring which was used as reference for the adjust-
ment. Upon completion of this operation, lock the RA and RC wheels with
the corresponding CR wheels (fig.7) and remove the reference F ring.
10) FITTING THE ELECTRIC BRAKE AND RELEASE DEVICE
Should it be required, a reversible model can be made irreversible by fitting
the EF Kit (Fig. 9):
1) Fix rotating disc DR to motor shaft A by means of screw VR using a
thread-locking glue for more efficient tightening.
2) Insert steel wire F in spring-holder pin PM and in disc DF, making it also
go through spring M and electromagnet E.
3) Use two screws VF to fix electric brake casing C to motor casing nuts D.
4) Manually pull the steel wire, if this lifts disc DF by more than 1mm, loosen
dowel GF and tighten dowel GR, so that the disc DF stroke is approximately
1mm; when this operation is completed, lock dowel GF in position.
5) Insert steel wire F into appropriate sheath G, which must have the cap
resting against hood C.
6) Having fitted the gearmotor, guide the sheath inside the spring-holder
shaft, trying not to create tight bends at points S.
7) Fully screw together two release knob elements P and insert steel wire F,
until sheath G is compressed, then fix the wire to the lower knob element
and lock dowel Gm.

11) EMERGENCY RELEASE

The emergency release device makes it possible to manoeuvre the roll-up
door manually.
X130/X130P:
In the case of models without electric brake, simply open the lock, if fitted,
and then manually lift the roll-up door, thereby forcing the gearmotor to a
reversible movement.
X130EF/X130PEF:
Install the release control at a maximum height of 1.8 m.
In the case of models with no electric brake, unscrew the two release knob
elements (Fig. 10) in order to release the gearmotor brake and thus allow
the roll-up door to be opened manually. To reset motor-driven operation,
retighten the knob.
In the case where the emergency release device is external, prepare a
small safe provided with a personalised key, where to insert the release
knob.
12) OPERATOR USE
Since the operator can be controlled remotely and therefore out of sight, all
the safety devices must be regularly checked for perfect efficiency.
WARNING! In the case of any malfunction in the safety devices, request
prompt assistance from qualified personnel.
Children must be kept at a safe distance from the operator working area.
13) CONTROL
The use of this operator allows roll-up door access to be automatically
controlled. There are different types of control (manual, remote, magnetic
card access, presence detector etc.) depending on the installation require-
ments and characteristics. See the relevant instructions for the various
control systems.
14) MAINTENANCE
WARNING! Before carrying out any maintenance operation, disconnect the
power supply.
These are the points which need checking and maintenance:
- Check that the roll-up door slides evenly along its entire stroke, without
any friction. If the manoeuvre is difficult, grease the sliding tracks.
- Check the photocell optical elements, if any. Clean them occasionally.
- Check the safety edge, if any. Periodically check that the edge stops the
roll-up door in the presence of any obstacle.
- Periodically check that the toothed crown wheel (Fig. 1-P) is lubricated.
- When any operation malfunction is found, and not resolved, disconnect
the power supply and request the assistance of a qualified technician
(installer). When the operator is out of service, activate the emergency
release device in order to allow the roll-up door to be opened and closed
manually.
15) SCRAPPING
Materials must be eliminated in compliance with the current regulations. In
case of scrapping, the operator components do not entail any particular risk
or danger. In case of materials to be recycled, these should be sorted out by
type (electrical components, copper, aluminium, plastic etc.).
