Electrical Connections - Nice Neo Tandem Series Instructions And Warnings For Installation And Use

3.3 - Other installation work
3.3.1 - Changing the direction of the cable outlet
(on Neo Tandem L version only)
To change the direction of the cable outlet, refer to fig. 6:
01. Pull the protection cover in the direction of the arrow to remove.
02. Bend the cable in the required direction.
03. Re-fit the protection cover by pressing it firmly into its seat.
3.3.2 - Replacing a damaged power cable
(on Neo Tandem M and Neo Tandem L versions only)
If the power cable (or connector) is damaged, it must be replaced with an identical version
available from Nice Technical Assistance.
Replacing the cable on the Neo Tandem M motor (fig. 9):
A. Turn the ringnut to align the chamfered edge with one of the coupling teeth, then
release.
B. Repeat the same operation for the other tooth.
Bend the cable inwards and remove the protection by turning it gently outwards.
C.
D. Pull the connector out to remove.
Replacing the cable on the Neo Tandem L motor (fig. 10):
Pull the protection outwards to remove.
A.
Pull the connector out to remove.
B.
3.3.3 - Installing the wall-mounted pushbutton panel
Install a control pushbutton panel on the wall, taking care to observe the following:
– Each Era Tandem system can be connected and controlled via a single pushbut-
ton panel (fig. 12). To connect it, refer to fig. 11. In the case of multiple systems,
they cannot all be controlled via the same pushbutton panel (fig. 13).
– Select a 2-button panel (Up and Down).
– It is advisable to use a "hold-to-run" pushbutton control panel, i.e. it is necessary
to press and hold the button for the desired duration of the manoeuvre.
– Position the pushbutton panel in sight of the awning but far from moving parts.
– Position the pushbutton panel to the side of the awning, where the "master" tubu-
lar motor power cable and the mains power cable are located.
– 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.
- A disconnect device must be installed on the product power supply line, with a gap
between contacts to ensure complete disconnection in overvoltage category III, in
compliance with installation regulations (the disconnect device is not supplied with
the product).
To make the electrical connections, refer to the wiring diagram in fig. 11. The dia-
gram shows the connection between the two motors, connection of a control push-
button panel, connection to the mains and connection to a switch for disconnection
from the mains. The following table shows the purpose of each wire.
"MASTER" motor cable – 6 wires:
1 - Yellow-green: = System "earth" (equipotential bonding connection).
2 - Blue: = System "Common" (usually connected to Neutral).
3 - Brown: = system electrical ascent (or descent) phase.
4 - Black: = system electrical descent (or ascent) phase.
5 - Violet: = "slave" motor electrical ascent (or descent) phase.
6 - Red: = "slave" motor electrical descent (or ascent) phase.
"SLAVE" motor cable – 4 wires:
7 - Violet: = "slave" motor electrical ascent (or descent) phase.
8 - Red: = "slave" motor electrical descent (or ascent) phase.
9 - Blue: = "Common" (usually connected to Neutral).
10 - Yellow-green: = "Earth" (equipotential bonding connection).
• Associating the Up and Down movements with the respec-
tive pushbuttons
After making the connections, run a number of manoeuvres (*) to ensure that the
ascent and descent movements are associated correctly with the respective control
buttons. If this is not so, invert the connection of the Brown and Black wires.

PROGRAMMING
5.1 - Programming warnings
• In general
- Strictly observe the time limits specified in the procedures.
- Positions 0, 1 of the awning, specified in the text, correspond to those illustrated in
fig. 14.
- During installation and adjustment, while final electrical connections are still to be
made, the system can be controlled with the specific Nice "TTU" unit (fig.15).
5.2 - Limit switch programming
Limit switches "0" and "1" (fig. 14) correspond to the positions of the awning at the
end of the Up movements ("0") and the end of the Down movements ("1").
To select the procedure most suited to the system features, refer to fig. 17.
5.3 - 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 manoeuvre (to set the required torque
value, refer to paragraph 5.6).
This function is enabled by default, but will not work if the limit switches are pro-
grammed using the manual procedure (paragraph 5.4).

WARNINGS FOR DAILY USE OF

THE AUTOMATION
6.1 - Maximum continuous work cycle
In general the tubular motors, while guaranteeing a maximum continuous use of 4
minutes, are designed for residential applications and therefore for discontinuous
use. Therefore in the event of overheating (for example due to continuous and pro-
longed activation ) a thermal cut-out trips automatically to shut off power supply.
Power is only restored when the temperature returns to within the normal range.
What to do if ...
(troubleshooting guide)
q When an electrical phase is powered up, the system does not move:
Provided that a thermal cut-out has not tripped, in which case it is sufficient to
wait for the system to cool down, perform the following checks.
• Ensure that the mains voltage corresponds to the data stated in the technical
specifications of this manual, measuring the voltage between the "common" wire
and that of the powered electrical phase.
• Check the connection between the two motors and the mains.
• Lastly, try powering up the opposite the electrical phase.
q When a command is sent, the system seems to start (a noise can be heard)
but fails:
• Check the connection between the two motors and the mains.
• A thermal cut-out on one of the two motors may have tripped; wait for the rela-
tive motor to cool.
• Ensure that the direction of rotation of the two motors is coordinated to enable
the awning to move up and down.
q The system still runs in emergency conditions, i.e. in hold-to-run condi-
tions:
• Check whether the motors have been subject to an electric shock or substan-
tial mechanical stress.
• Check the mechanical condition of all motor parts.
• Run the deletion procedure (paragraph 5.7) and program the limit positions
again.
