BFT LUX Serie Installations- Und Gebrauchsanleitung Seite 23

2) GENERAL OUTLINE
A compact, sturdy oleodynamic piston, available in a wide range of models to fit
any need and field of operation. It is available in versions both with or without
(reversible) hydraulic lock, that need to be equipped with an electric lock to hold
the gate both closed and open.
The emergency release is obtained with the special key provided.
The adjustment of the pushing force is extremely precise and is performed by means
of two by-pass valves that act as an antisquash safety. The operation at the end of the
stroke is controlled electronically by a timer in the control panel.
The LUX series includes special versions with slowdown in the closing phase (Mod.
"R") while the LUX FC series is especially suited to areas prone to heavy snowfalls or
where the central gate stop cannot be provided (see specific instruction manual).
Warning: during the first manoeuvring cycles, some oil may leak out after being
deposited in the breather channel during transport.
Warning: an excessively fast manual manoeuvre can cause oil to leak out.

5) INSTALLATION OF THE ACTUATOR
5.1) Preliminary checks
Check:
• that the structure of the gate is rigid and strong enough. In any case, the
actuator must push against a reinforced point in the leaf
• that the leaves move manually without excessive effort for the whole of their
stroke
• that the door stops are mounted on the leaves
• If the gate being installed is not new, check whether its components are
worn.
Repair or replace any worn or damaged parts.
Automation reliability and safety are directly influenced by the condition of the
gate's structure.

INSTALLATION MANUAL
5.2) Installation values
The values to be known for installation can be found in the table related to the
model being installed (fig. 3-4), with reference also to the diagram in fig. 5.
The diagram in fig. 5 uses the following legend:

α°
5.3) How to read the installation dimensions (fig- 3-4)
From the tables (fig. 3-4), select "a" and "b" according to the angle in degrees α°
that the gate has to open. Each table shows the ideal value for "a" and "b" for an
opening of α° = 90° at constant speed.
In this condition, the sum of "a" plus "b" gives the value of the working stroke
"Cu" (fig. 2).
If there is too large a difference between "a" and "b", the leaf will not travel smoothly
and the pushing or pulling force will fluctuate during its stroke.
When "a" and "b" are at their maximum, the piston develops the maximum force.
This condition is particularly useful for heavy gates or gates with very long leaves.
WARNING! The LUX models having a rod with adjustment ball joint enable the rod
to be lengthened or shortened by about 6 mm., but only if it is set in the position
shown in fig. 9 before being installed. When installed, this adjustment will allow
for correcting the stroke of the rod. Fig. 10 shows the oscillation to which the LUX
models with front and rear joint are subject with respect to the horizontal axis.

5.4) Off-standard installations
Fig. 6 - need for a recess to house the controller when the leaf is completely
opened;Fig. 6 gives the size of the recess for the different LUX models.
Fig. 7 - if the "b" value is higher than the values listed in the installation tables, the
leaf's hinge pivot should be shifted, or a recess be made in the gate-post (fig. 8).
5.5) Mounting the brackets to the gate-post and to the gate-leaf.
Fix the bracket "P" (fig. 11) to the gate-post with a good welding.
The fork "F" should be welded in the same way to the gate leaf along the distance
"C" as shown in fig. 5, taking care that the operator is installed within the limits
shown in Fig. 10.
5.5) Mounting the brackets to the gate-post and to the gate-leaf.
• If the gate-post is in brick, the plate " PF" must be welded to a metal base (mod.
PLE) and set soundly into the post using adequately sized cramps "Z" welded
to the back of the plate (fig. 12).
• If the gate-post is in stone, the plate "PF" welded to a metal base (mod. PLE)
can be fixed with four metal expansion plugs "T" (fig. 13). If a larger gate is
being installed it would be better to weld the plate "PF" to an angular base
(fig. 14).
6) GROUND GATE STOPS
For the controller to operate correctly the gate stops "F" must be used both in
opening and closing, as shown in fig. 15.
The gate stops should prevent the rod of the actuator from reaching its end of
stroke . Fig. 16 gives the values which ensure a perfect installation when the
actuator is performing the pushing or pulling function. They must be placed
so that about a 5-10 mm margin of travel is maintained in the rod. This margin
prevents any malfunctions.
