Product Description And Intended Use; First Power Up - Nice NX STAR MB 534 SH Instructions And Warnings For Installation And Use

PRODUCT DESCRIPTION AND
INTENDED USE
This product is a tubular motor for automating roller shutters (fig. 2). Do not use
it for any other purpose! The manufacturer declines all liability for damage
resulting from improper use of the product or any other use than that speci-
fied in this manual.
The product has the following functional characteristics:
• it is mains powered (see the motor's nameplate ratings);
• it installs inside the winding roller; the part of the motor that protrudes from the roller
(electronic head) mounts to the ceiling or wall with brackets (not included);
• it has a built-in control unit with encoder technology that electronically controls the
movement and precision of the limit switches;
• it can be programmed with a wall-mounted button panel or with a TTU programmer
(fig. 5). These accessories are not included;
• it can be commanded with a cabled wall-mounted push-button panel (fig. 4). We
recommend the use of a fixed or momentary switch with interlocked push buttons
(accessory not included in the package);
• it can move the roller shutter up or down; stop it at the upper limit switch "0", the
lower limit switch "1" or at various intermediate positions "H");
• it moves roller shutters of different weights at the same speed;
• the up and down speeds are the same;
• it features acceleration and deceleration, respectively at the beginning and end of
the movement;
• it features a security system that detects the presence of an obstacle along the roll-
er shutter's path, immediately blocking the movement in progress and performing
a brief inversion of movement. The same system is automatically activated at the
end of the Up movement (only if the upper limit switch "0" consists of a box or oth-
er mechanical stop), to mitigate the impact of the roller shutter against the housing
and loosen the tension exerted by the motor on the canvas, when the roller shutter
is stationary at the upper limit switch "0";
• is equipped with a "thermal protection device" which, in case of extended use, pro-
tect the motor against excessive overheating by limiting the motor speed to the min-
imum speed; in this way, the continuous usage time increases, allowing extended
use (until the thermal protection device intervenes);
• it is available in a variety of versions, each with a specific motor torque (see the mo-
tor nameplate ratings).

INSTALLATION OF THE MOTOR AND
THE ACCESSORIES
2.1 - Preliminary checks before installation and lim-
itations on use
• Check the condition of the product right after unpacking it.
• Make sure that the torque, the rotation speed and time of operation of this motor
are suitable for automating your roller shutter. In particular, do not install the mo-
tor if its torque is greater than that needed to move your roller shutter. To
choose the right motor to the technical features of your roller shutter refer to the the
"Guide to Selection" section, in the "Nice Screen" catalogue, – also available on the
www.niceforyou.com website.
• Check the diameter of the winding roller. This must be chosen according to the
motor torque, as follows:
– For motors of size "M" (Ø = 45 mm), the minimum inside diameter of the winding
roller must be 52 mm.
• Additional limitations on use are listed in chapters 1 and 2 and in the technical cha-
racteristics on the nameplate.
2.2 - Assembling and installing the tubular motor
Caution! – Read the safety warnings before proceeding. Incorrect installation
could cause severe physical injury.
To assemble and install the motor, refer to fig. 3 (the accessories shown in fig. 3 are
not included in the package). To select the limit switch gear wheel (fig. 3-a), drive
wheel (fig. 3-b), motor bracket (fig. 3-f), or to select supplementary cables (of dif-
ferent lengths), refer to the "Nice Screen" catalogue, which is also available on www.
niceforyou.com.
2.3 - Installing a wall-mounted push-button panel
Install a push-button command panel on the wall, observing the following warnings:
– for correct use of the automated system you need to install a push button panel
with 2 buttons: one for Up and one for Down;
– to use the automation, once installation has been completed you can use a push-
button panel with any mechanical operation of the buttons, except for the op-
eration that allows you to simultaneously press the two buttons;
– for the control of a single motor, only a single push-button panel can be installed;
– for the control of more than one motor connected in parallel (max. 8) only a single
push-button panel can be installed;
– for the confidentiality of the automated system, it is recommended that you install
the push button panel in a place not accessible to unauthorized persons;
– install the push button panel in a place from where you can see the roller shutter;
– install the push button panel away from the moving parts of the roller shutter;

Position "0" = UPPER limit switch
Position "1" = LOWER limit switch
– install the push button panel on the side of the roller shutter where there is the
electrical cable from the motor and the power cable from the electricity mains (fig.
3-i);
– install the push button panel at a height of at least 1.5 m from the floor.

ELECTRICAL CONNECTIONS AND

FIRST POWER UP

3.1 - Connecting the motor to the power supply
and a push button control panel
To connect the motor to the power supply and a push button control panel (*), refer
to fig. 4. The connection cable has four wires:
CABLE "A" (refer to fig. 4)
Wire Colour Connection
A1 Brown Electric phase of up/down.
A2 Black Electric phase of up/down.
A3 Blue Common (usually connected to Neutral).
A4 Yellow-Green
Earth (equipotential protection connection).
(*) Note – Since the subsequent motor installation and programming operations
must be done with the "TTU" Programmer (fig. 5), it is recommended that you
make the final connection of the push button panel only after these operations.
WARNINGS:
• Incorrect connections can cause faults or hazards; therefore ensure that the in-
structions in this paragraph are strictly observed.
• The electrical connections must be made only after installing the motor and the
compatible accessories required.
• The motor must be powered by a permanent connection to the mains.
• The power cable is connected to the motor via a connector; this is removable (fig.
3-h) and allows the replacement of the cable (refer to the "Nice Screen" product
catalogue, also available on the website www.niceforyou.com).
3.2 - Installation of the protective devices inside
the electricity power network
In accordance with the electrical installation regulations, the network that powers the
motor needs to have a protection device against short-circuits and a disconnection
device from the mains (the two devices are not present in the package). Caution!
– The disconnection device must have an opening distance between con-
tacts, that allows complete disconnection of the power supply, under the
conditions laid down in the overvoltage category III.
The disconnection device must be placed in a position that is visible from the au-
tomated system and, if it is not visible, there must be a system for preventing acci-
dental or unauthorized reconnection with the power grid so as to avoid any possible
hazard.
