Technical Specifications; Actuator Installation; Preliminary Checks - BFT ELI 250 BT Instructions 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 BT 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 appear-
ance 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 BT 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 controlled by special end-of-stroke magnetic sen-
sors and by mechanical stop blocks located inside the foundation case.
CAUTION! The actuator mod. ELI 250 BT is not provided with mechanical
torque adjustment. It is compulsory to use a control board of the same
manufacturer, according to the basic safety requirements of directives
2006/95/CEE, 2004/108/CEE, 2006/42/CEE and provided with adequate
electric torque adjustment.
3) MAIN AUTOMATION PARTS

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! It is recommended to use the following cables:
• Connection to the mains: multipolar cable with minimum cross section
of 3x1.5 sq mm.
• Connection to the control unit:
- Operator farthest from the control unit (Fig.2)
for the motor: 2x2.5 sq mm cables;
for the limit switch sensors: 3x1 sq mm cables.
- Operator nearest to the control unit (Fig.2)
for the motor: 2x1.5 sq mm cables;
for the limit switch sensors: 3x1 sq mm cables.
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
-1
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
3.5m/2500N (~250kg) 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.14).
Let the cement harden for the time needed.
6) GATE LEAF FITTING
• Abundantly grease the pivot in the foundation case.
• Position the lever a ssembly b y inserting p ipe " A" into the pivot o f the foundation
case, as in fig.9. If the height of the assembled levers is not sufficient, insert
shim "S" between the assembled lever unit and the gate leaf, as in fig.5.
• Place the gate leaves in the closing and in the closed position against the
centre stop plate.
• Perfectly align the assembled lever unit to the hinge.
• If a shim is used, weld it to the leaf first and then weld the lever unit to the shim.
• Check the leaf operation.
• If the gearmotor is not to be installed, fit the foundation case cover and fix
with suitable screws.
At this stage, the gate opens and closes manually. All that remains to be done
is to position the gearmotor.
7) GEARMOTOR FITTING
Remove the nuts from the bottom of the case using a CH19 socket wrench.
• Fit the end-of-stroke sensors (Fig. 6A).
• Select left-hand or right-hand fixing position (Fig.6A).
Plate sides are marked as follows:
• Secure the plate on the gearmotor by means of the three M8 screws as shown
in Fig. 6B. After mounting the gearmotor on the foundation case, connect the
control unit in order to be able to move the output lever and then tighten the
other two M8 screws (Fig.9).
• Secure the magnet onto the plate as shown in Fig. 7. Then install the plate as-
sembly onto the gearmotor outlet shaft and determine the diagonal position
of the holes (R-L) for right or left fastening (Fig.7).
• Secure the gearmotor to the foundation case in the position indicated in Fig.
9 using the 4 nuts previously removed.
