9.1 CHOICE OF THE HINGES TO BE MOTORIZED
For doors that have 2 hinges, you can
choose to motorize the high or low hinges
indifferently.
For the shutters that have 3 hinges it is
recommended to motorize the central
hinge.
Provide for the installation of the opening
stroke stops.
Also install the closing stroke stops, both at
the top and at the bottom.
It is possible to install a closing electro-
piston at th
e top or at the bottom
(optional).
10. PHISICAL INSTALLATION OF THE AUTOMATION
10.1 CHECK OF LEAF MOVEMENT AND FASTENING
The automation you are installing integrates a safety device which, detecting impediments, stops the
movement of the doors. For this reason, it is necessary to check, even before installing the automation,
that the doors have compatible characteristics as per the table on page 4 (in particular the maximum
weight of the door of 50kg / 75Kg and the door that must not exceed 1.5 sq.m. / 2.0 sq.m. for each door).
It is also necessary to check the rotation of the leaves, which must rotate smoothly, free and without
obstacles. We suggest carrying out this check by closing the door and pushing it from the closed position.
With a normal push, the door should open completely until it touches the opposite wall. If the door
exhibits 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 door that presents problems will
reduce the life of the automation, which will be unnecessarily fatigued for its entire life of use.
Furthermore, once connected, it will be more complex to identify this type of problem that must therefore
be solved initially.
10.2 ENGINE POSITIONING
Install and lock the doors in the closed position. Use the template supplied by inserting it into the strips to
be motorized and mark the point where to drill with a pencil.
When marking the core drill holes make sure the jigs are snug against the wall

10.3 DRILLING THE WALL
Remove the doors and use the hammer drill with the
core drill bit.
Drill the wall with a depth of 150mm making sure to be
perpendicular to the wall both vertically and horizontally
For the passage of the sheath for the electrical
connection, drill with a 16-20mm bit
Thoroughly clean the holes with a vacuum cleaner and wire brush to allow the chemical
sealant to take hold
10.4 ASSEMBLY OF THE AUTOMATION
Unscrew the two screws that hold the motor fixed to the shell and remove the motor from the casing.
Prepare the electrical sheath to allow the passage of the cables and leave a cable length of 200mm outside
the wall, section 2x1.5mmq.
Insert the gaskets and connect the cables following the wiring diagram. The NEGATIVE pole is marked with
a white dot on the rear of the engine. Insert the motor in the cover and fix it with the screws previously
unscrewed.

Fix the strips to the doors and insert the doors on the hinges.
Pay particular care and attention to the alignment of the manual hinges with the motorized
hinge. Always keep in mind that the reference for alignments is always the motorized hinge. If
it is necessary to protrude further, it is possible to order 10mm extensions to be interposed
between the hood and the motor block.
Use the notches present in the cap to insert the chemical glue into the spaces between the hole in the wall
and the cap. Start clockwise from hole 1 up to number 4 as you gradually use more and more adhesive.
Once finished, go over the outermost part following the entire perimeter, taking care to clean the surplus
of material.
Wait for the chemical adhesive to dry respecting the times and methods recommended by the
manufacturer
Fit the protection flange
The protection flange will be spaced a few mm from the masonry

10.5 ASSEMBLY OF THE DOOR ON THE MOTORIZED HINGES
Disassemble the doors and mark the point to be drilled 20mm from the upper edge of the eye of the strip.
Drill the eye of the strip with a 6.5mm metal drill, the hole must be through and perfectly perpendicular or
parallel to the door.
To make the holes in the strips easier, a template (optional) is available that guides the tip
both in height and in direction.
It may be necessary to widen the holes present in the hinge of the motor to allow the passage of the
through pin, or use the supplied dowel. Reassemble the doors, rotate the doors until it is possible to insert
the through pin.

11. ELECTRICAL INSTALLATION PREPARATION
WARNING
!
The electrical installation must be carried out following the national standards in force, thus for all the
obligations established by law. The electrical connections must be made without voltage, do not power
the work area before completing all assembly operations.
RADIO SPECIFICATIONS
Frequency: 433.92 Mhz Transmitter range: approx: 70m free field
The good propagation of radio waves depends on the nature of the environments to pass through.
The range of radio waves is affected by the type of construction.
12. AUTOMATION OPERATION
The automation operates the doors after pressing the button and continues to move them until the button
is pressed. The operator switches off automatically when the effort is detected, with the leaf completely
open or completely closed. The closing / opening force must be set appropriately by means of a trimmer
(see chapter “Adjustment trimmer”). To stop the leaves at an intermediate point during movement, simply
stop pressing the button.
Make sure that there is a soft pad in the upper corner of the door or a small dark man
without automatic release, so that the door always remains free and can rest without
marking itself. In this way, the motorization will also be able to better determine the “All
Open” position.
These elements are generally charged to the supplier of the shutters, but can be supplied as
accessory elements upon request.
13. ELECRTICAL CONNECTION
Assembly must be carried out by a qualified electromechanical operator. CHIAROSCURO SAS exonerates
itself from any responsibility in case of bad installation and / or installations made by unauthorized
operators. (Minimum card size 145 x 105mm)
The proper functioning of the equipment and compliance with
safety requirements are
guaranteed only if connected to an efficient electrical system built in accordance with the
laws in force (in Italy Legislative Decree 37/2008). The manufacturer assumes no
responsibility for any damage to the equipment or to third
parties caused by the use of a
system that does not comply with current regulations.
If the behavior of the equipment does not reflect the above, do not use the automation and
immediately report the anomaly to the authorized CHIAROSCURO SAS service cent
er. Never
open the enclosure of the equipment unless expressly authorized in writing by
CHIAROSCURO SAS. Failure to comply with this rule results in the immediate forfeiture of
the warranty and consequent liability of CHIAROSCURO SAS for aspects concerning
the
safety and operation of the equipment.
It is the sole responsibility of the electromechanical operator to set up the system.
CHIAROSCURO SAS is in no way responsible for any deficiencies of any natu
re on the
system. All the information necessary fo
r a good system is fully available, it is the buyer's
responsibility to request them formally.

16. COMPATIBILITY WITH HOME AUTOMATION SYSTEMS
The automation is compatible with almost all home
automation systems and existing home automation
management modules that manage the opening and closing of
the shutters (modules that can be purchased from specialized
dealers). As for the control of rolling shutters, it is in fact
sufficient to set a retention time of more than 60 seconds
using your favorite application: the automation will perform
the movement and automatically stop when the doors are
opened / closed. The integrated card is in fact able to stop the
motors when the movement is complete, identify any
obstacles or presences during operation, in order to guarantee
maximum safety during operation and to protect the motors
from stress. This simplified use makes automation extremely
easy to manage and configure! We suggest that you check the
compatibility of your home automation module by consulting
your trusted dealer, showing him this type of simplified use
and these wiring diagrams. You can also contact our
technicians who will be happy to provide you with further
technical and functional details.
17. ADJUSTMENT TRIMMER
The board, as standard, is pre-wired and configured with pre-optimized “default”
parameters that are valid for most users and types of common use.
It is not recommended to modify the default parameters of the electronic board, which
must only take place when necessary. The modification of the configuration parameters
must only be made by knowledgeable and qualified operators.
17.1 TRIMMER TEMP:INCREASE OF THE OPENING DOORS DELAY:
Adjusting the TEMP trimmer allows you to set
the opening delay between the leaves.
Clockwise rotation decreases the opening
delay time between the leaves, on the
contrary, anticlockwise rotation increases it.
Carry out some opening and closing tests to
check that the doors in the movement phase
do not have overlapping and jamming.

P.I. IT01527050221 Pag.17 di 20
17.2 TRIMMER CURR: INCREASE OF THE MOTOR POWER:
Adjusting the CURR trimmer allows you to
set the thrust torque.
By setting a thrust level too low, the leaves
will lock in an anomalous way, while too
much power would lead to a single effort of
the motors when the stroke is complete. We
suggest identifying the minimum operating
point and from that position, increase the
power by ¼ of a turn.
18. SPECIAL PROGRAMMING FUNCTIONS
18.1 REVERSAL OF THE FIRST DOOR
Of Standard, the first door to open is the right. To reverse the first door to open it is necessary to open the
cover and reverse the cable connections to the electronic board.
ATTENTION: To reverse the opening direction of the leaves, as well as swap the motor cables
on terminal blocks M1 and M2, it is also necessary to reverse the polarity by connecting the
RED cable instead of the BLACK cable for each motor.
19. ELECTROPISTON ASSEMBLY
The electric lock is an optional accessory
and must be mounted near the stop of
the main door when closing. On the
door, on the other hand, a small
perforated flange will be mounted
which, when in the closed position, this
hole must coincide with the solenoid
lock.
The electric lock cables must be routed
to the right, usually, or to the left,
providing a duct for their protection,
until they reach the electronic board.
N.B. our system is able to manage elected 24V powered pistons that do not exceed a
current draw of 600mA
20. MAINTENANCE
The operations described in the following paragraphs must always be carried out with the equipment
off (equipment disconnector in the OFF position).
In the event that defects / malfunctions are found, do not try to repair the equipment but contact the
service center indicating the model, code and serial number of the equipment (see Fig.3.1. Plate data

22. DISPOSAL
INFORMATION FOR USERS
Pursuant to art. 13 of the Legislative Decree 25 July 2005, n. 151
"Implementation of Directives 2002/95 / EC, 2002/96 / EC and 2003/108 / EC,
relating to the reduction of the use of hazardous substances in electrical and
electronic equipment, as well as the disposal of waste"
The crossed-out bin symbol shown on the equipment indicates that the product
at the end of its useful life must be collected separately from other waste. The
user must, therefore, deliver the equipment complete with the essential
components at the end of its life to the appropriate separate collection centers
for electronic and electrotechnical waste, or return it to the retailer when
purchasing new equipment of an equivalent type, at the one by one. Adequate
separate collection for the subsequent start-up of the discarded equipment for
recycling, treatment and environmentally compatible disposal helps to avoid
possible negative effects on the environment and health and favors the
recycling of the materials that make up the equipment. Illegal disposal of the
product by the user involves the application of administrative penalties
provided for by current legislation.
23. Limits of liability
WH25 offers a torque of 25 Nm, WH50 offers a torque of 50 Nm: these are the maximum driving torques
available on the transmission pin which, through the arm and track, impart movement to the leaf or
maintain its position. It is the responsibility of the buyer / installer to determine whether this pair is
adequate for the needs of the required application; the needs depend on various factors mainly: weight
and dimensions of the leaf (the indications given in chap.11.2 are purely indicative and not binding),
friction of the hinges and correct verticality of the rotation axis of the same, and above all the extent of the
opposing force generated by the wind. The intensity and duration of wind stresses are highly variable and
in the absence of complex and expensive measurement and recording procedures they can only be
estimated not in a subjective and approximate way. In the offer, the supplier company expresses an
evaluation of these factors based first of all on data and information made available by the customer and
possibly emerged from the inspection, but such evaluations cannot be considered contractually binding
and binding for the purpose of attributing responsibility to the supplier company in the choice and
adequacy of the supply to the specific case as only with a pilot installation made in the case considered by
the most significant customer can the real needs / problems of the application emerge. The various
mechanical elements are designed to cope with the stresses and normal wear resulting from the torque
generated by the apparatus for a number of 20,000 operating cycles. However, there are stresses and
consequent wear that do not depend on the drive torque but depend on poor installation and above all on
stresses caused by the wind when the intensity or frequency of the gusts / gusts are significant or linked to
consistent atmospheric phenomena.
Precisely because of the unknown entity and type of said stresses, the resistance of the apparatus for this
purpose cannot be guaranteed.
