Technical Specifications; Preliminary Checks - BFT ELI-250 Instructions D'utilisation Et D'installation

Thank you for buying this product, our company is sure that you will be more
than satisfied with the performance of the product. This product is supplied
with a "Warnings" leaflet and an "Instruction manual". These should both be
read carefully as they provide important information about safety, installation,
operation and maintenance.
WARNINGS: Any assistance required on automation components must be
carried out by a qualified technician (installer).
2) GENERAL OUTLINE
The ELI-250 electromechanical actuator is the ideal solution for underground
hinge-pivot installation. The actuator consists of a perfectly sealed single-block
reduction gear. The under hinge-pivot position maintains the aesthetic appearance
of the gate and practically hides the automation system.
Once the bearing case is installed, the gate can be operated even without fitting
the actuator which can be inserted later. When maintenance is required, this type
of case allows the actuator to be taken out without removing the gate leaf. The
ELI-250 actuator can be fitted to any type of swing gate which meets the values
shown in the "Technical Specifications" table. The pushing force is set on the
control unit (see specific manual).
The end-of-stroke operation is adjusted by mechanical stops located inside the
foundation case.
CAUTION! The actuator mod. ELI-250 is not provided with mechanical torque
adjustment. It is compulsory to use a control board of the same manufactu-
rer, according to the basic safety requirements of directives 2004/108/EEC,
2006/95/EEC, 2006/42/EEC, 99/05/EEC and provided with adequate electric
torque adjustment.
3) MAIN AUTOMATION PARTS
Sealed mechanical actuator (fig.1) including:
a) Single-phase 2-pole motor protected by thermal circuit-breaker.
b) Double worm-screw reduction gear with output gear in special aluminium
alloy.
c) Output lever and mechanical stops.
d) Bearing foundation case (ready for automation).
e) Series of levers for gate movement.
f ) Release unit with key.
CAUTION! The actuator can be fitted either on the left or on the right, which are
conventionally defined by looking at the gate from the inside (opening direction).

5) ACTUATOR INSTALLATION

5.1) Preliminary checks

Check that:
• The upper hinge is in good condition and possibly adjustable.
• A hole can be dug for burying the case under the hinge.
• The "FA" stop plates of the leaves are installed (fig.8).
• Repair or replace the faulty or worn parts of the structures to be subjected to
movement.
An exploded view of the installation is shown in fig.1.
The automation reliability and safety are directly influenced by the state
of the gate structure.
5.2) The main automation components are (Fig.2):
I) Type-approved adequately rated omnipolar circuit breaker with at least
3,5 mm contact opening, provided with protection against overloads and
short circuits, suitable for cutting out automation from the mains. Place,
if not al ready installed, a type-approved differential switch with a 0.03A
threshold just before the automation system.

5.3) Electrical installation set-up
Lay out the electrical installation as shown in fig. 2, with reference to the CEI 64-8
and IEC 364 provisions, complying with the HD 384 and other national standards
in force for electrical installation. The mains power supply connections must be
kept totally separate from the service connections (photocells, electric edges,
control devices etc.).
WARNING! For connection to the mains power supply, use a multicore cable
with a cross-sectional area of at least 3x1.5mm
the regulations in force.
To connect the motors, use a cable with a cross-sectional area of at least
1.5mm
The cable must be type H05RN-F at least.
Connect the control and safety devices in compliance with the previously men-
tioned electrical installation standards. Fig. 2 shows the number of connections
and the cross section for cables having a length of approximately 100 metres; in
case of longer cables, calculate the cross section for the actual automation load.
Warning! For actuator wiring and accessory connection, refer to the relevant
instruction manuals. The control panels and accessories must be suitable for use
and conform to current standards.
5.4) Foundation case cementing
The foundation case must be cemented under the hinge pivot, taking into con-
sideration that the actuator bearing shaft must be perfectly aligned with the leaf
rotation axis. If the gate has fixed hinges, remove the gate and the lower hinge.
If the leaf is sufficiently separated from the ground and cannot be removed,
proceed to supporting it by means of a shim placed between the ground and
the leaf during installation. If the gate has adjustable hinges, remove the lower
one, slacken the upper hinge and move the leaf to the side. If the gate has been
recently installed, fit an upper adjustable hinge. Dig a foundation hole having the
dimensions specified in fig.4. Lay an drain pipe (fig. 4) for rainwater in order to

prevent it from being collected inside the foundation case. Lay a raceway for the

power supply cable as far as connector block "D". Lay a solid foundation (fig.3) at the
bottom, where to bury the foundation box. To obtain good squareness between
cases and leaves, set out their alignment using a stretched rope between the 2
bearing pivots, and aligning the 2 reference points "C" with each other (see fig.12).
Let the cement harden for the time needed.
