3.2 - Tubular motor assembly and installation
Caution! - Before proceeding with assembly and
installation of the tubular motor, carefully read the
warnings in paragraph 1.2. Incorrect installation
can lead to serious injury.
To assemble and install the tubular motor, refer to fig.
6. Consult the Nice product catalogue or the web site
www.niceforyou.com to select the limit switch ring (a),
the drive ring (b) and the motor fixing bracket (e).
• Installing the wall-mounted pushbutton panel
Install a control pushbutton panel on the wall, taking
care to observe the following:
– use exclusively "hold-to-run" type pushbutton pan-
els, i.e. when the pushbutton must be pressed and
held for the required duration of the manoeuvre.
– select a 2-button panel (Up and Down).
– position the pushbutton panel in sight of the awning
but far from moving parts.
– position the pushbutton panel to the side of the
awning, in the location of the electric cable from the
tubular motor and power cable routed from the elec-
tric mains.
– position the pushbutton panel at a height of at least
1.5 m from the ground.

ELECTRICAL CONNECTIONS

Caution!
- Incorrect connections can cause faults or hazardous
situations.
- Strictly observe the connections specified in this
manual; if in doubt, do not proceed; refer to the rela-
tive technical datasheets, also available on the site
www.niceforyou.com
- The electrical power line must be fitted with a device
that enables complete disconnection of the product
from the mains. The disconnection device must have
a gap between contacts that ensures complete dis-
connection in the conditions of overvoltage category
III, in compliance with installation regulations.
For electrical connections, refer to the wiring diagram in
fig. 7. The cable for electrical connections of the tubu-
lar motor has 4 internal wires:
– Brown: = electric ascent phase.
– Black: = electric descent phase.
– Blue: = Common (usually connected to Neutral).
– Yellow-green: = Earth (equipotential bonding con-
nection).
• Associating the Up and Down movements with
the respective pushbuttons
Check that the up and down movements are correctly
associated with the relative control buttons. If this is not
the case, invert the connection between the Brown
and Black wires.
When the UP or DOWN buttons are pressed, ensure
that the awning completes 2 brief movements (=
operator connected correctly). Note - the direction of
motor rotation is not important.

PROGRAMMING
5.1 - Programming warnings
• In general
- Strictly observe the time limits specified in the proce-
dures.
- Positions 0, 1, 2, and S of the awning, specified in
the text, correspond to those illustrated in fig. 5.
- During installation and adjustment, while final electri-
cal connections are still to be made, the tubular motor
can be controlled with the specific Nice "TTU" unit.
• Motor signals
❏ The motor implements one very short interruption at
the start of the manoeuvre and then resumes move-
ment = only 1 limit switch is memorised.
❏ The motor implements two very short interruptions
at the start of the manoeuvre and then resumes move-
ment = no limit switch is memorised.
❏ when the control button is pressed ("hold-to-run"
mode), movement is started but is interrupted shortly
afterwards, without completing the manoeuvre = the
tubular motor has set to "emergency" mode and the
intervention of a specialist technician is recommended
to eliminate the cause of the problem
5.2 - Limit switch programming
Limit switches "0" and "1" (fig. 5) correspond to the
positions of the awning at the end of the Up move-
ments ("0") and the end of the Down movements ("1").
To select the procedure most suited to the system fea-
tures, refer to fig. 4.
Note on "RDC" function
The RDC function prevents the canvas from remaining
excessively tensioned at the end of the closing ma -
noeuvre. The function automatically reduces the motor
traction torque during the final phase of the closing
