cer or mechanical transmissions or brushes
are used, which results in a dramatic reduction
in the noise produced by the system.
The electrical board controls the various fun-
ctions of the motor, including those related to
the blind stops (end stops) in its extreme posi-
tions. The amperometric protection device al-
lows it to recognise the natural end stops of the
blind and memorises them, so that the system
will automatically stop in their vicinity (without
reaching the limit positions), increasing the li-
fespan of the blind components; the magnetic
transmission system, on the other hand, fur-
ther reduces the risk of damaging the parts.
The desired end stops of the blind can also be
set manually at any height, via some special
sequences of pulses to be performed from the
external push buttons.
The ScreenLine®external motor must be con-
nected to the corresponding 24V dc power
supplier or, using 3.6V dc voltage power, to the
The ScreenLine® external motor can be tted
to all double glazing units that make use of the
ScreenLine®frontal magnetic transmission sy-
stem and allows their tilt, raising and lowering
movement.
For easy application and removal (if necessa-
ry), the item has been divided into two compo-
nents: a support and a removable body.
The support contains the external connection
contacts and must be applied onto the ma-
gnet of the integral blind.
The removable body incorporates the motor
and the electrical board. An operation LED, an
infra-red receiver and a dip-switch for board
conguration can be accessed from the exter-
nal glass cover.
The motor installed is a rotating-case brushless
motor mounted on bearings, directly coupled
with the external motor magnet, in order to
achieve a direct motion transmission (“Direct
Drive” technology). Therefore, no speed redu-
battery-operated ScreenLine system featuring
an optional self-charging solar panel. In the lat-
ter case, no wiring needs to be done on the
window frame.
The motor and, consequently, the blind, opera-
te by means of the polarity inversion of power
supply, which can be carried out by means of a
couple of push buttons, or via remote control,
or by means of the battery module from the
battery-operated system.
The dedicated software features two operation
speeds so as to optimise and synchronise the
slat tilting function, which is also improved by
the quartz oscillator.
Should centralised control alongside push
button control be requested, it is advisable that
one or several SL1807 or SL1963 (radio) con-
trol units be used in order to rationally manage
several groups of motors.

Preliminary operations
The external motor must be applied onto the
double glazing unit only after tting the latter
into the window frame. Make sure that there
is sufcient room to accommodate the mo-
tor: the internal spacer bar must be aligned or
protruding inwards with respect to the glazing
bead. Should this not be the case, reduce the
thickness of the double glazing unit support
blocks.
Arrange the supply cables inside the window
frame, close to the position of the magnet of the
integral blind, leaving the upper glazing bead
open.
Make sure also that the glazing bead has a
sealing gasket, in order not to pinch the cables
coming out of the electric motor, which must be
connected to the power supply. When no ga-
sket is available, cut a slot in the glazing bead,
near the area where the cables come out of the
motor. Doing this will prevent the cables from
being sheared or trapped when the glazing
bead is closed.
Attaching the support to the glass
The surface of the glass where the external
motor is to be attached must be perfectly clean.
Use isopropyl alcohol if necessary and wait a
few moments for it to dry.
Arrange the cable outlet from the motor support
so that the cables are facing upwards, so that
they can enter the upper glazing bead.
Peel off the three protective lms from the adhe-
sive tape on the motor support.
Draw the support nearer to the glass, centring
it with the internal magnet of the blind. Use the
specially supplied cardboard centring piece to
help with this. This centring piece has a cutout
diameter equal to the external diameter of the
magnet located inside the double glazing unit.
Make sure that the motor support is parallel with
the window frame.
Press the support rmly onto the glass to allow
good adhesion, pressing all over its surface
against the inside as well.
IMPORTANT: please remove the cardboard
centring piece before applying the motor body
(see Fig. 3)
Electrical connections
Three wires (white, black and yellow) come out
of the outer motor support.
Connect the three wires to the cables coming
from the power supply and housed inside the
frame. Follow the electrical diagrams in the
technical catalogue.
Suitably protect the cable joint and hide the
excess cable inside the window frame above
the glazing unit.
Close the upper glazing bead, making sure that
the cables are not squeezed by it.
Fitting the motor
Insert the motor body, sliding it onto the sup-
port until the respective catch at the end of the
support clicks.
When the connections are made, ensure that
the motor works properly, using the push-but-
tons connected thereto.

followed by a pause of at least three seconds.
At the beginning of the programming proce-
dure, all the values already memorised or set
must be cancelled.
To reset the system, with the blind placed in
the upper end stop position, raise the blind
for 10 to 15 seconds. In order to facilitate the
programming sequence, the motor LED is lit
in the rst 10 seconds and blinks between 10
and 15 seconds.
To programme the upper end stop, take the
blind to the required top position, make four
short pulses on the up button: up-pause-up-
pause-up-pause-up-pause.To programme the
lower end stop, take the blind to the required
bottom position, then make four short pulses
on the down button: down-pause-down-
pause-down-pause-down-pause. If during
the setting operation your pulses should more
than 3 seconds (which can be checked by the
resulting movement of the blind), the program-
ming functions are cancelled and the procedu-
Setting the end stops
The upward and downward end stops of the
blind are memorised automatically (self-lear-
ning function) during the rst cycle (full raise/
lower) of operation of the blind: the ampero-
metric system on the electrical board detects
the sudden increase in current and sets the
end stop of the blind close to that position.
In case of very thick inner glass panes (thicker
than 8 mm), the amperometric system may
not detect the end stop and the magnet then
will slip, without damaging the internal compo-
nents of the blind or the motor.In this case the
end stops must be set using the procedure de-
scribed below: the same procedure can also
be used if the installer wants to set different
end stops, at the customer’s request (e.g. the
tilt only function on venetian blinds). The reset
and end stop setting operations can be carried
out directly from the external buttons with an
appropriate sequence of short pulses, lasting
less than three seconds. Each pulse must be
Setting the dip-switches
Under the glass cover there is a dip-switch
(see Fig. 1) allowing conguration of the motor
electrical board for operating with the integral
blind.
To access the dip switches, lift the cover, using
the recess in the body.

OFF: direct system
Dip switch No. 3: infrared remote control ena-
blement
ON : remote control disabled
OFF: remote control enabled
Dip switch No. 4: type of blind
ON : roller or pleated blind
OFF: venetian blind
Setting up the infrared receiver
In order to use the external motor with the infra-
red remote control, the third dip-switch must be
set to “OFF”, as described above, and the rele-
vant jumper must be removed from the contact
accessible from the hole located under the body.
It is possible to keep the jumper by placing it onto
a single contact pin, as shown in Fig. 2.
Using the motor with 3.6V dc supply
The external motor can be connected to
the battery module in order to achieve self-
standing automatic operation. To activate this
function, the relevant jumper must be applied
onto the contact located under the body Fig.
2 (near the one for activating the infrared re-
mote - see Fig. 2).
re must be started again.
In case an infrared remote control is provided,
setting the end stops must be done only throu-
gh pulses from the remote, following the pro-
cedure described below. To reset the system,
press the central button “S” on the remote
control for 4 seconds until the LED lights up
conrming that cancellation of the end stops
has taken place. To set up the upper end stop:
take the blind in the desired top position, then
press button S, then press the up button im-
mediately for 4 seconds until the LED lights up,
which conrms that programming the upper
end stop has taken place. To set up the lower
end stop: take the blind in the desired lower
position, then press button S, then press the
down button immediately for 4 seconds until
the LED lights up, which conrms that pro-
gramming the lower end stop has taken place.
Please note that in this case, the external but-
tons are only enabled for raising, lowering and
stopping the blind.
Replacing the motor
The body of the external motor can be removed
from the glass, without the electric cables having
to be disconnected or the glazing bead having to
be opened. Push down on the catch located at
the bottom of the body (it is in a hidden position,
to prevent vandalism). Slide the body out from the
support, pushing the body towards its glass cover.
Set-up and adjustment
Accessories for the External Motor
The external motor is compatible with all the
accessories intended for the internal motor,
described in the leaet “Electrical components
for ScreenLline motorised blinds” and, for the
battery-operated system, described on the cor-
responding leaet devoted to the accessories of
model SL20-22F. Should the client so require, he
can control the motor via a push-button (to be
sourced locally) whose features match the speci-
cations reported in drawings 100, 102 and 103.
In cases like this, the black cable must suitably
connected. Please refer therefore to those do-
cuments, bearing in mind that, if using all above
mentioned accessories, the motor cables to be
used for this purpose are the white and the yel-
low, while the black must NOT be used.
Operation of the motor
The brushless motor works at low voltage (3.6
Vdc or 24 Vdc) with polarity inversion. Inver-
sion is carried out directly from the external
buttons or by means of control units (SL1807
or SL1963).
The electronics on board the motor optimises
the various functions, the most important of
these being the constant speed and the rpm
count, kept by the encoder.
The blind is moved by pressing the up and
down buttons from the switch or the corre-
sponding keys on the remote control.
With venetian blinds, if the button/key is pres-
sed for a period of less than three seconds,
the blind moves at slow speed and then stops
when the button/key is released. This function
allows the orientation of the slats to be optimi-
sed, until the required angle is reached.
If the button/key is kept pressed for more than
three seconds, the blind moves at high speed,
even after the button/key is released, until the
preset end stops are reached.
With roller and pleated blinds, the blind starts
off straight away at high speed and there is no
three-second wait (if dip switch No. 4 is cor-
rectly set on its “ON” position).
To stop the movement of the blind and therefo-
re stop the motor, just make one pulse on any
button/key.

Important note
The motor body should be left in its box and
not taken out till it is to be tted to its support.
Avoid contact between motor bodies, as the
sudden mutual attraction could cause dama-
ge to the magnets. When handling the mo-
tor body, keep it at safe distance from metal
objects that could be strongly attracted by the
magnet, as this could also cause damage to
the latter. Furthermore, please note that the
magnet may attract small metal bodies that
may come between the glass and the magnet,
this causing the motor fail to operate.
