6.2 IDENTIFYING THE TYPE OF APPLICATION
6.3 WARNING FOR INSTALLATION TYPES 4,5,6 AND DERIVATIVES
Particular care must be taken when the net passage clearance is between 80 and 90cm and the A2
shoulder dimension is greater than 12cm.
It is advisable to position the slider in the track so that when the sash is open it is at least 8 mm from the
end of the track. Make sure that the 90° end does not touch the sash (recommended minimum distance of
5mm).

In order to increase this distance, you can use the adjustment slots on the 90° end and on the forearm. In
general, the articulated arm must always have enough space to extend when closing. Installations with L1
(light inside the window) smaller than 80cm/160cm are only possible after checking with the
"Chiaroscuro" technical office. If A2 is larger than 12cm, it may be necessary to distance the automation a
few centimetres from the window wall abutment (Dimension A1, see previous drawing) to avoid contact
between the 90° terminal and the sash.
.
• If there is limited space available between closed shutters and closed glazing - distance "D5" - or if the
maximum permitted D = 200 mm is to be used, distance "D1" can be reduced by up to 2 mm so that guide
rail 2 in closing will have to pass under the arm and distance "D6" will be approx. 20 mm.
• The length of the 90° terminal "t1", for TIP.1, 2 and 3, is designed so that when the sash is closed the
articulated arm fits into the 77 mm space occupied by the motor unit. In the case of particular sash shapes,
TIP.4, 5, and 6, it is necessary to use a 90° Padovian terminal, extended to prevent the arm from touching
the sash at point "P" - the edge of the hinge - before completing the opening stroke. The 90° Padovian
terminal increases the overall dimensions of the closed joint to 120 mm instead of 77 mm. Please note that
when using the 90° padovan terminal, if the distance "D" is already max. 200 mm, the dimension "D4+D2"
could be greater than 400 mm to allow the articulated arm to extend when closing.
MAXIMUM WIDTH
DMAX MM.
The values in the table are valid for doors with a thickness of 40 mm,
type 4,5, 6 and derivatives. A margin of at least 5 mm should always be
kept in relation to the values in the table. In cases where the values are
below 5 mm, it is preferable to proceed with a dimensional test in the
field and/or on a sample to establish with certainty whether the space
available is sufficient to move the shutters correctly.

The thrust efficiency of the motorisation improves as the "X" measurement increases, which is the
distance measured on the vertical axis between the fulcrum of rotation of the motor arm and the slider
located on the track, and the position of the slider with respect to the hinge. Bear in mind that the more
the slider is moved towards the centre of the sash, the greater the opening efficiency of the motorisation.
Moving the drive towards the centre of the window increases the efficiency of the drive, but at the same
time increases the overall length of the joint. During installation, once the position of the motor has been
determined from the wall abutment and with respect to the shutter, open the sash and ensure that the
end joint is as extended as possible, guaranteeing a minimum distance between the joint and the shutter
of at least 5mm at each point of rotation of the sash..
It should be noted that the ST50/ST100 product is specifically for casement windows and doors.
Any other use does not guarantee correct functioning and compatibility with CE marking.

8. CHOICE OF APPLICATION TYPE
SIDE-BY-SIDE GUIDANCE
Position the drive as shown in the adjacent figure.
There must be approximately 20 mm between the
automation and the internal edge of the leaf. If, for
various installation reasons, this distance is
exceeded, you must:
•In any case, make sure that you comply with the
specifications given in the drawing in chapter
"Installation note".
•Please note that increasing the distance reduces
the thrust on the sash.
GUIDE BELOW
Position the motor flush with the leaf as shown. The
guide must be positioned under the automation as
shown in the figure. Between the leaf and the
automation, leave a space that prevents the leaves
from coming into contact with the automation
when they are fully closed.
RECESSED AUTOMATION
Depending on the type of material your lintel is
made of, the distance between the edge of the wall
and the drive can vary, but must never be less than
40 mm. If this measurement increases, remember
to check that the dimensions given in chapter 7.3
are respected.
Mounting accessories:
Sheet metal for flush-mounting omega plate for
fastening the automation (only with side-by-side or
underneath rail)

9. PHYSICAL INSTALLATION OF THE AUTOMATION
9.1 CHECKING DOOR MOVEMENT AND FIXING
The automation you are installing incorporates a safety device which, by detecting obstacles, stops the
movement of the leaves. For this reason, it is necessary to check it before installing the automation,
9.2 CHECKING DOOR MOVEMENT AND FIXING
The automation you are installing incorporates a safety device that, when it detects obstacles, stops the
movement of the leaves. For this reason, even before installing the automation, it is necessary to check
that the leaves have compatible characteristics, as indicated in the table in chapter 7 (in particular, the
maximum leaf weight of 70 kg/140 kg and the maximum leaf surface area, which must not exceed 1.8
sq.m./2.5 sq.m. for each leaf). These indications are not exhaustive: for further information please refer to
chap. 22. It is also necessary to check the rotation of the leaves, which must rotate fluidly, free and
unobstructed. We suggest carrying out this check by closing the leaf and pushing it from the closed
position. With a normal push, the leaf should open fully until it touches the opposite wall. If the shutter
shows some friction in its movement, it is necessary to suspend the assembly phase of the automation and
intervene on the hinges and elements of the shutter that compromise the fluidity of movement, making
the appropriate changes to the elements that create friction. A problematic shutter will reduce the life of
the automation, which will be unnecessarily fatigued throughout its life of use. Furthermore, once
connected, it will be more difficult to detect these types of problems, which must therefore be resolved
initially.
9.3 POSITIONING THE MOTOR
The template provided can be used to determine the position of the drive and the relevant fixing holes. In
the case of installation with a guide rail underneath, the template must be cut with scissors at the dotted
line.
9.4 MOTOR MOUNTING TEMPLATE
The template is designed for a predefined installation of the motors. In some types of use it
may be necessary to increase the distance of the motors from the wall abutment, as the thrust
efficiency of the joints on the sashes is particularly affected by the position of the motorisation
and increases as the motors move closer to the centre of the window.

9.5 POSITIONING THE TEMPLATE
Draw a line on the upper transom of the window hole for the position of the closed sashes. Align the
template with the drawn line, taking care to lay it against the wall abutment at the same time. The text
printed on the template must be facing downwards. Mark the position of the holes in the reveal, drill and
insert the Fischer plugs supplied.
Fix the aluminium extrusion carrying the motor and the electronic board to the ceiling
using the high-strength screws provided, taking care to use the washer between the
screw and the aluminium extrusion.

(pos.03) and push the support extruder (pos.01) out a few centimetres, as in the photo, taking care that
the central casing is well aligned, parallel to the shutter and wall edge. Slide both the central casing (03)
and the support casing (02) so as to bring the support extrudate (01) closer to the wall shoulder and mark
the position of the hole (N.B: it is not necessary for the support extrudate to be positioned in adherence to
the wall shoulder). Mark the position of the hole and fix the support extrudate.
Once the support extrusion is fixed to the
vault, position the support casing and
extend the central casing until it is flush
with the wall shoulder.

10.7 POSITIONING EXTRUDED CENTRAL SUPPORT L=100MM.(ST100 WINDOWS L=1600 /2000)
LEGEND:
1
Extruded support carter L=100mm. in natural aluminium
2
Support carter L=100mm. in natural aluminium finish
3
Central casing Available in matt white RAL9010, matt black RAL9005 or natural aluminium finishes
The supporting extrudate (pos.01), is to be fixed to the vault by means of a single fixing point. In order to
mark the position of this hole precisely, we recommend fixing at least one motor extrudate, positioning the
motor casing and the centre casing. Mark the position of the window centre. Position the support casing
(pos.02) at the end of the central casing (pos.03) and protrude the support extrusion (pos.01) a few
centimetres, as in the photo, taking care that the central casing is positioned parallel to the shutter and the
wall edge. Slide both the central casing (03) and the support casing (02) so as to position the support
extrusion (01) in the centre of the window. It is important that the casings are well aligned with each other
to form a compact, linear element. Mark the position of the hole and fix the central support extrusion.
Once the support extrusion is vaulted, position the
support casing (2) and extend both central casings
from the right-hand and left-
hand motors, (03)
aligning them with
the centre of the window,
effectively making the central support "disappear".

10.8 ADJUSTING THE ARTICULATION,POSITIONING AND FIXING OF THE SLIDING RAILS
After fixing the extruder, connect motor 2, if present, and the power supply to the circuit board. Place the
cover on the motors and then position the forearms.
The bolts must be positioned in the lower part of the joints and
the pan head screws must be positioned in the upper part, to
prevent the bolts from touching the motor casing when the
arms are closed, damaging it and preventing the doors from
closing properly.
Slide the ends of the joints along the slots until they reach the
maximum possible extension, making sure that the forearm is
not in contact with the shutter or the wall for any reason
(minimum safety distance 5mm). When the shutter is open, the
slider should be positioned as far as possible from the hinge,
towards the centre of the shutter (minimum distance 4cm., see
picture): this optimises the thrust efficiency of the joint.
.
Open the doors and align the rail with the slider and mark a first rail position on the door. Check that the
slider runs across the whole surface of the rail without pushing or pulling the joint and forcing it to swing
up or down. The joints must maintain the same natural tension in each position of the slider in the rail,
otherwise friction will fatigue or in the worst case interrupt the movement of the automation and over
time deteriorate it. It is also advisable to carry out a check during the opening/closing phases of the leaf to
make sure that the slider on the leaf never leaves the guide. After carrying out the checks, tighten the
forearms firmly to the motor and the terminals to the forearms.
11. AUTOMATION OPERATION
The drive operates the leaves when the button is pressed and continues to move them as long as the
button is pressed. The drive switches off automatically when the force is detected, when the door is fully
opened or fully closed. The closing/opening force must be set appropriately via trimmers (see chapter
"Setting trimmers"). To stop the leaves at an intermediate point during movement, it is sufficient to stop
pressing the button.
Ensure that there is a soft buffer in the upper corner of the sash or a blind stop without
automatic triggering, so that the sash always remains free and can be supported without
scoring. These elements are generally the responsibility of the shutter supplier, but can be
supplied as accessories on request.
