3.7_ Electrical connections
All electrical connections must be made withthe sy-
stem disconnected from the power supply.
1_
To open the protection cover and access the electronic con-
trol unit of T-SKY, press on the side of the cover and turn the
panel door as shown in fig. 35.
2_
Route the connection cables to the various devices through
the cable clamps, leaving a length 20÷30cm more than nec-
essary. See para. 2.2 for the type of cables and figure 3 for
connections.
3_
Make the connections as shown in the diagram in figure 36.
Terminals are removable to facilitate connections.
3.8_ Connecting to the power supply
For electric power supply of T-SKY simply connect the 230 Vac line
to the transformer safety fuse holder (A fig. 36).
T-SKY must be connected to the power mains by skil-
led and qualified personnel, in possession of all requi-
rements for full compliance with all legal provisions,
standards and regulations.
The electric power line must be protectedagainst short
circuits and dispersion to earth; a device must be fitted
to enable shutoff of the power supply during installa-
tion or maintenance of T-SKY.

transformer in relative compartment of T-SKY motor
and protected by fuse on the 230 Vac power line.
1-4
(Photocell) PHOTOCELL OR SAFETY DEVICE input ac-
tive on closure (Normally Closed contact); when activated,
during the closing phase, generates a door stop command
followed by complete door re-opening; in the opening
phase generates a temporary stop command until the de-
tected obstacle is removed (only if dip switch nr. 3 is set to
ON). In the case of multiple safety devices, connect all NC
contacts IN SERIES. 1= PHOTOCELL .

N.B.
The photocell transmitter must always be powered by
terminals 5 and 6, as the safety system check is per-
formed on the latter (Fototest).
To disable the safety system test function, or when
using the photocells, set dipswitch 6 to OFF. If the fo-
totest function fails, there is a control unit fault.
2-4
(Stop) STOP button input (Normally Closed contact); stops
the door at any point of travel, temporarily inhibiting auto-
matic closure, if programmed. It resumes operation when
the OPEN/CLOSE button is pressed or radio control is
used. 2= STOP, 4= COMMON
3-4
(Open/Close) OPEN/CLOSE button input (Normally Open
contact); activates door opening and closing and is control-
led by operation of dipswitches 2 and 4. 3= OPEN/CLOSE.
5-6
(Photocell TX) 24 Vdc output, for PHOTOCELL TX POW-
ER SUPPLY (only those that perform the Fototest function)
max. nr. 1 photocell transmitter.
5= NEGATIVE, 6= POSITIVE.
6-7
(Photocell RX) 24 Vdc output, max. 15 W, for POWER
SUPPLY OF RX AND POSSIBLE OTHER TX ELEMENTS
OF PHOTOCELLS, EXTERNAL RECEIVERS etc; connect
max. 3 pairs of photocells. 6= POSITIVE, 7= NEGATIVE.
8-9
(Flashing light) 24 Vdc FLASHING LIGHT output (max. 15
W). The signal supplied is already specially modulated for
direct use. The flashing frequency doubles during the clos-
ing phase. 8= POSITIVE, 9= NEGATIVE.
10-11 (Antenna) AERIAL input for built-in RX 433,92 MHz. 10=
EARTH, 11= SIGNAL.

IMPORTANT: After powering up the control panel, wait for 2
seconds before starting the adjustment procedures.
F 2 A
On completion of automation installation:
24 Vdc
1_ bring the door to approx. 1 m from the closing stop;
24 Vdc
2_ position dipswitch no. 10 to ON;
5 Vdc
3_ activate the automation via one of the following inputs: O/C,
radio control or board button (O/C).
-20 °C ÷ +70 °C
4_ the door should start to close.
IP 30
N.B.: if the door opens, suspend programming and reset the
electrical panel (disconnect the panel from the power
supply for at least 5 sec. and return dipswitch no. 10 to
OFF), and while disconnected, invert the motor supply
wires. Then resume the procedure from point 1.
5_ at the end of closure, after an interval of approx. 2 seconds, a
total opening and new closing cycle is performed automatically;
6_ at the end of closing, wait for led DL3 to light up permanently,
then position dipswitch no. 10 to OFF;
7_ the automation is now ready for operation.
Make the logic settings.
N.B.: by means of any adjustment device on the control
panel (trimmers or dipswitches) perform a complete
manoeuvre (opening and closing) of the automation to
apply the new settings.
