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 first 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 first 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 configuration 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.
Dip switch No. 1: width of the cavity
ON: cavity 27 mm or 32 mm
OFF: cavity 20 mm or 22 mm
Dip switch No. 2: Internal blind control device
ON : reduced system
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
confirming 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 confirms 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 confirms 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.

Accessories for the External Motor
The external motor is compatible with all the
accessories intended for the internal motor,
described in the leaflet “Electrical components
for ScreenLline motorised blinds” and, for the
battery-operated system, described on the cor-
responding leaflet 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-
fications 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.
