2.3 - Typical system

Fig. 2 shows an example of an automation system set up with Nice components:
a - Control unit
b - Gearmotor
c - Flashing light
d - Photocell
e - Digital keyboard - Transponder reader - Key selector
f - Photocell post
g - Opening mechanical stops
h - Closure mechanical stops
These parts are positioned according to a typical standard layout. With refer-
ence to fig. 2, locate the approximate position for installation of each compo-
nent making up the system. Important – Before installation, prepare the electri-
cal cables needed for your system, referring to fig. 2 and "Table 1 - Technical
characteristics of electrical cables".
Connection
A: CONTROL UNIT POWER cable
B: FLASHING LIGHT with aerial cable
C: BLUEBUS DEVICES cable
D: KEY-OPERATED SELECTOR SWITCH cable
E: GEARMOTOR POWER cable
F: ENCODER CONNECTION cable
Note 1 – If the power cable is longer than 30 m, a cable with a larger cross-section is required (3 x 2.5 mm
of the automation.
Note 2 – If the Bluebus cable is longer than 20 m (up to max. 40 m), a cable with a larger cross-section is required (2 x 1 mm
Note 3 – These 2 cables can be replaced by a single 4 x 0.5 mm
Note 4 – These 2 cables can be replaced by a single 5 x 1.5 mm
IMPORTANT! – The cables used must be suited to the installation environment.

ELECTRICAL CONNECTIONS

The electrical connection of the various devices (photocells, digital keyboard,
transponder card readers, etc.) contained in the automation with the control
unit must be made by means of the Nice "Bluebus" system. This system allows
electrical connections to be made using just 2 conductors for both the electric-
ity supply and the communication signals. The electrical connection to be used
is of the parallel type and no polarity needs to be observed. During the learning
stage, the control unit will recognise individually all devices connected to it
thanks to a unique code. Each time a device is added or eliminated, it will be
necessary to make the control unit perform the learning operation (see para-
graph 3.4).
After mounting the control unit box and preparing the electrical cable holes
(chapter 2.4 and fig. 3), make the electrical connections:

IMPORTANT!

– All electrical connections must be made with the unit disconnected from
the mains power supply and with the buffer battery disconnected, if pres-
ent in the automation.
– Connections must be made exclusively by qualified personnel.
01. Connect first the electrical power supply cable (fig. 4) and then the electri-
cal cables of motors M1 and M2 (fig. 5).
02. Lastly, connect the electrical cables of the various devices present in the
system with reference to the electrical diagram in fig. 6.
Note – To facilitate cable connections, the terminals can be removed from
their seats.

Important – During installation of ducting for electrical cables and the introduc-
tion of cables into the control unit enclosure, be aware that due to possible
water deposits in the junction boxes, the connecting ducts may form conden-
sation inside the control unit which is liable to damage the electronic circuits.

2.4 - Installation of control unit

To mount the control unit, proceed as shown in fig. 3:
01. Open the control unit box by undoing the relevant screws (fig. 3-A);
02. Prepare the electrical cable routing holes (fig. 3-B);
03. Mount the box (fig. 3-C);
04. The electrical connections can now be made: see chapter 3.
Important! – To prepare the inlets for the electrical cable ducting, holes must
be drilled in the lower side of the control unit box. Note – If necessary, the lat-
eral cable inlet may be used, but only with the aid of suitable duct fittings.
To install the other devices present in the automation, refer to the relevant
instruction manuals.

2 ) and safety earthing is necessary in the vicinity
no polarity needs to be observed. Each device is individually
recognized because a unique address is assigned to it during
installation
STOP input for devices that cause the immediate interruption of the
manoeuvre in progress (with a short reverse run); NO and NC
contacts, as well as devices with 8.2 kΩ constant resistance
output (sensitive edges) can be connected to this input. Each
device connected to this input is recognised individually by the
control unit during the learning stage (paragraph 3.4); in this stage,
if the control unit detects any variations with respect to the learned
state, it causes a STOP. One or more devices of the same or
different kinds can be connected to this input:
– connect a number of NO devices in parallel without quantity limits;
– connect a number of NC devices in parallel without quantity limits;
– connect 2 devices with 8.2 kΩ constant resistance output in
parallel. If there are more than 2 devices, they must be connected in
a cascade with just one 8.2 kΩ termination resistance;
– connect 2 NO and NC devices in parallel, placing a 8.2 kΩ
resistance in series on the NC contact (this also allows for a
combination of three devices NO - NC and 8.2 kΩ)
P.P. input for devices which control Step-by-Step manoeuvres.
NO contacts can be connected to this input
OPEN input for devices which control only opening manoeuvre.
NO contacts can be connected to this input
CLOSE input for devices which control only closure manoeuvre. NO contacts
can be connected to this input
ENC1 input encoder – gearmotor 1 (terminal 1, 2); it is not necessary to
observe any polarity
ENC2 input encoder – gearmotor 2 (terminal 4, 5); it is not necessary to
observe any polarity
M1 output for gearmotor 1 (terminal 7, 8, 9)
M2 output for gearmotor 2 (terminal 10, 11, 12)
[*] The FLASH, ELS and S.C.A. outputs can be programmed with other func-
tions (see "TABLE 5 - 1st level functions"; or via Oview programmer, see chap-
ter 7.2).
IMPORTANT! – If the system has a single gearmotor, it must be connect-
ed to terminals of M2 (10, 11, 12).
