4 ELECTRICAL CONNECTIONS AND

FIRST POWER UP

During the installation and adjustment operations, the motor can be controlled by the
"TTU" unit (fig. 6) until the final electrical connections have been made.
4.1 - Connecting the motor to a control pushbutton
panel and the electrical mains
Warnings:
– Incorrect connection can cause faults or dangerous situations, therefore scrupu-
lously respect the instructions given in this paragraph.
– If the power supply cable is damaged, the product cannot be used because the
cable cannot be replaced. In these cases, contact the After-sales Ser vice.
The motor must be powered via a permanent connection to the electricity mains. To
connect the motor to the electricity mains and to a pushbutton strip, refer to fig. 7.
The connection cable wires are connected as follows:
– Brown = electric ascent ou descent phase.
– Black = electric ascent ou descent phase.
– Blue = Common (normally connected to the Neutral).
– Yellow-Green = Ground (protective
electrical bonding).

ADJUSTING LIMIT SWITCHES
5.1 - Programming the two limit switches
During raising and lowering movements the motor automatically stops the rolling shutter (or awning) when it reaches a limit switch (fig. 3): position "0"= (rolling shutter or
awning completely rolled up); position "1" = rolling shutter (or awning) completely unrolled. Proceed as follows to programme these positions.
Warnings:
• The two "arrow" buttons on the motor head are each used to programme a limit switch. The motor is supplied with these buttons pressed and therefore with limit switches
already programmed at arbitrary heights. Follow the procedure described below to adjust these heights to suit the specific features of your rolling shutter (or awning).
• At point 02 of the procedure, the first level to be programmed may be freely chosen as required.
01. Make sure that the two "arrow" buttons on the motor head
are released, that is, that the emerge all the way out of the
motor surface. If they are flush with the surface (pressed),
release them by pressing each button all the way down
with a screwdriver.
02. Use the wall-mounted pushbutton strip to position the
rolling shutter (or awning) at the desired level for the limit
switch (the High or "0" limit switch is shown in the exam-
ple). IMPORTANT! – while the manoeuvre is under-
way, observe the direction of rotation of the winding
roller and identify the arrow on the motor head point-
ing in the same direction as the roller turns. Then stop
the manoeuvre. Note – Use the two pushbuttons on the
wall-mounted pushbutton strip for fine regulation of levels.
03. Lastly, memorize the level by pressing the "arrow" button
identified previously all the way down (with a screwdriver)
on the motor head: it must stay down.
04. Use the wall-mounted pushbutton strip to adjust the other limit switch so that the rolling shutter (or awning) is at the desired level for this limit switch.
05. Lastly, memorize the level by pressing the "arrow" button not used before all the way down (with a screwdriver) on the motor head: it must stay down.
5.2 - To change only one of the two limit switch levels memorised
Proceed as follows to change a limit switch level which has already been memorised (without changing the other limit switch):
01. Use the wall-mounted pushbutton strip to move the rolling shutter (or awning) by a few centimetres in the direction of the limit switch to be modified: – while the ma-
noeuvre is underway, observe the direction of rotation of the winding roller and identify the arrow on the motor head pointing in the same direction as
the roller turns then stop the manoeuvre.
02. (on the motor head) With the rolling shutter (or awning) stationary, release the "arrow" button identified (press with a screwdriver).
03. Use the wall-mounted pushbutton strip to complete the manoeuvre interrupted in point 01, putting the rolling shutter (or awning) at the new limit switch level. Note –
Use the two pushbuttons on the wall-mounted pushbutton strip for fine regulation of levels.
04. (on the motor head) With the rolling shutter (or awning) stationary at the limit switch, memorize the new level by pressing the "arrow" button all the way down (using a
screwdriver) on the motor head: it must stay down.
4.2 - Installing safety devices in the electrical mains
In compliance with the electric installation rules, in the network that powers the
motor, a short circuit protection device and a disconnection device from the mains
electricity must be envisioned (the two devices are not present in the package). Cau-
tion! – The disconnection device must have an opening distance between
contacts which is sufficient to permit complete disconnection from the
power supply under the conditions required by overvoltage category III.
The disconnection device must be located in view of the automation and, if it is not
visible, must envision a system that blocks any accidental or unauthorised re-con-
nection of the power supply, in order to prevent any danger.
4.3 - Associating the Up and Down movements with
the respective pushbuttons
On completion of connections, power up the motor and check whether the Up and
Down movements are associated correctly with the relative control pushbuttons. If
this is not the case, invert the connection between the Brown and Black wires.
