sioned as specified in the chapter on "Testing and commissioning".
• Inspect the automation mechanism frequently to check for unbalancing, signs
of wear or damage to electrical cables and mechanical parts. Do not use the
automation mechanism if adjustment or repair is required.
• If it is not used for a long time, remove the optional battery (PS124) and keep
it in a dry place to make sure it does not leak harmful substances.
• The packing materials of the product must be disposed of in compliance with
local regulations.
1.3 - Warnings about use
• The product is not intended for use by persons, including children, with lim-
ited physical, sensory or mental capacities, or who lack experience or knowl-
edge, unless supervised or trained in the use of the product by a person
responsible for their safety.
• Any children near the automation system must be kept under supervision to
ensure that they do not play with it.
• Do not allow children to play with the fixed control devices. Keep remote
control devices out of their reach as well.
• Clean the surfaces of the product with a soft, slightly damp cloth. Use only
water; do not use cleaning products or solvents.

PRODUCT DESCRIPTION AND INTENDED USE
This product is intended to be used to automate sliding gates used in residential
premises. WARNING! – All uses other than the intended use described
and use in environmental conditions other than those described in this
manual should be considered improper and forbidden!
Slight combines an electronic control centre with a finger joint. Electrical con-
nections with external devices are simplified thanks to use of the "BlueBUS", a
technique permitting connection of multiple devices with only 2 wires.
If powered from the grid, Slight can host a buffer battery (mod. PS124, optional
accessory) which permits the automation mechanism to continue to perform
a number of manoeuvres even in the event of a black-out. In the event of a
black-out, it is still possible to move the gate by releasing the gearmotor using
the key provided (see paragraph 3.7); or you may use the optional accessory:
the PS124 buffer battery that permits a number of manoeuvres even in the
absence of grid power.
The automation mechanism permits installation of various accessories to add
functions and improve security.

INSTALLATION
3.1 - Tests prior to installation
Caution! - The installation of SLIGHT must be carried out by qualified
personnel in compliance with current legislation, standards and regula-
tions, and the directions provided in this manual.
Before proceeding with the installation of SLIGHT you need to make these
checks:
• Check that all the materials are in excellent condition, suitable for use and
that they conform to the standards currently in force.
• Make sure that the structure of the gate is suitable for automation.
• Make sure that the weight and dimensions of the leaf fall within the specified
operating limits provided in chapter "3.2 Operating limits".
• Check that the force required to start the movement of the leaf is less than
half the "maximum torque", and that the force required to keep the leaf in
movement is less than half the "nominal torque". Compare the resulting val-
ues with those specified in Chapter "8 Technical Characteristics".The manu-
facturers recommend a 50% margin on the force, as unfavourable climatic
conditions may cause an increase in the friction.
• Check that the internal dimensions of the column are appropriate (at least
140 x 140 mm)
• Check the seats prepared for fixing the column
• Check that there is enough space in the area at the back, inside the column
to insert the gearmotor and to pass the cables through and connect them.
• Check that the column is correctly earthed in the installation.
• WARNING! – Make sure that the column has been prepared correctly in
compliance with local legislation and guarantees a protection of at least IP44
when the lid is closed.
• Make sure that there are no points of greater friction in the opening or closing
phases of the gate leaves.
• Check that there is no risk of derailment or that the leaves may come off their
guides.
• Make sure that the mechanical stops are sturdy enough and that there is no
2 – English
risk of deformation even if the leaf hits the mechanical stop violently.
• Make sure that the gate section is balanced, i.e. it must not move if left still in
any position.
• Make sure that the area where the gearmotor is fixed is not subject to flood-
ing; iff necessary, mount the gearmotor raised from the ground.
• Make sure that the installation area enables the release of the gearmotor and
that it is safe and easy to release it manually.
• Make sure that the mounting positions of the various devices are protected
from impacts and that the mounting surfaces are sufficiently sturdy.
• Components must never be immersed in water or other liquids.
• Keep SLIGHT away from heat sources and open flames; from acid, saline
or potentially explosive atmospheres; this could damage SLIGHT and cause
malfunctions or dangerous situations.
• If there is an access door in the leaf, or within the range of movement of the
gate, make sure that it does not obstruct normal travel and, if necessary,
provide an appropriate interblock system.
• Connect the control unit to an electricity supply with a safety earth system.
• Connect the gate to the protective earth in accordance with current legislation.
• Provide a device on the electricity supply line that ensures complete dis-
connection of the automation mechanism from the grid. The disconnection
device must have contacts with an opening distance large enough to per-
mit complete disconnection under the conditions sanctioned by overvoltage
category III, in accordance with installation regulations. The device ensures
quick, safe disconnection from the power supply if needed, and must there-
fore be positioned in view of the automation mechanism. If, on the other
hand, it is located in a position which is not visible, there must be a system
for preventing accidental or unauthorized reconnection with the power grid to
prevent this risk. The disconnection device is not supplied with the product.
3.2 - Operating limits
Information on the performance of products in the SLIGHT range are supplied
in the chapter on "Technical Characteristics" and this is the only information
needed to determine whether the products are suitable for the intended appli-
cation.
The structural characteristics of SLIGHT make it suitable for use on sliding
leaves in conformity with the limits indicated in tables 1 and 2.
The effective suitability SLIGHT to automate a particular sliding gate depends
on the friction as well as other correlated factors, such as ice, that could inter-
fere with the movement of the leaf.
For an effective control it is absolutely vital to measure the force necessary to
move the leaf throughout its entire run and ensure that this is less than half
of the "nominal torque" indicated in chapter 8 "Technical characteristics" (a
50% margin on the force is recommended, as unfavourable climatic conditions
may cause an increase in the friction); furthermore, it is necessary to take into
consideration the data indicated in tables 1 and 2 to establish the number of
cycles/hour, consecutive cycles and maximum speed allowed.
SLIGHT - Limits in relation to the length of the leaf
Leaf width (m)
Up to 4
4 ÷ 6
SLIGHT - Limits in relation to the weight of the leaf
Leaf weight (kg)
Up to 200
200 - 400
The length of the leaf makes it possible to determine both the maximum num-
ber of cycles per hour and consecutive cycles, while the weight makes it pos-
sible to determine the reduction percentage of the cycles and the maximum
speed allowed. For example if the leaf is 5 m long it will be possible to have
23 cycles/hour and 11 consecutive cycles. However, if the leaf weighs 350
Kg, they must be reduced to 50%, resulting in 11 cycles/hour and 5 consecu-
tive cycles, while the maximum speed allowed is V5: "very fast". The control
unit has a limiting device which prevents the risk of overheating based on the
load of the motor and duration of the cycles. This device triggers when the
maximum limit is exceeded. The manoeuvre limiting device also measures the
ambient temperature reducing the manoeuvre further when the temperature is
particularly high.
