• Ensure that the space around the product enables easy and safe access.
• Make sure that all the electrical cables used are of the type listed in Table 1.
• Make sure that the automation is provided with mechanical stops on both
closing and opening.

2.2 - Product application limits

The MC824HR control unit may only be used with the Toona gearmotors model
5624I; these motors are reversible: i.e. it is possible to manually move the leaves
of the gate without having to manually release the gearmotor. Thanks to a sen-
sor inserted in the motor, the control unit is able to detect the manual move-
ment of the leaves while correctly managing the subsequent manoeuvres; this is
necessary to avoid the leaves hitting the opening and closing mechanical stops.
Caution! - If the control unit is not correctly powered or if the "stand By all"
function is active, the manual movement of the leaves is not detected.

2.3 - Typical system

Fig. 2a shows an example of an automation system set up with Nice components:

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.
3.1 - Description of electrical connections (fig. 6)
AERIAL input for the radio receiver aerial
FLASH output for 1 flashing light with 12V (maximum 21W) bulb. [*]
ELS output for 12Vac (maximum 15VA) electric lock. [*]
S.C.A. "Open Gate Light": output for 1 indication lamp (24V maximum
4W). [*]
BLUEBUS input for compatible devices (MOFB, MOFOB, MOB and MOTB);
they are connected in parallel using two conductors through which
both the electricity supply and the communication signals travel;
no polarity needs to be observed. 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 paragraph 3.6).
STOP input for devices that cause the immediate interruption of the
manoeuvre in progress (with a short reverse run); NO and NC con-
tacts, as well as devices with 8.2 kΩ constant resistance output
(sensitive edges) can be connected to this input. Each device con-
nected to this input is recognised individually by the control unit
during the learning stage (paragraph 3.6); in this stage, if the con-
trol 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 lim-
its;
– several NC devices can be connected in series, with no limits as
to quantity;
– connect 2 devices with 8.2 kΩ constant resistance output in par-
allel. If there are more than 2 devices, they must be connected in
a cascade with just one 8.2 kΩ termination resistance;

These parts are positioned according to a typical standard layout. With refer-
ence to fig. 2a, locate the approximate position for installation of each com-
ponent making up the system. Important – Before installation, prepare the
electrical cables needed for your system, referring to fig. 2b and "Table 1
- Technical characteristics of electrical cables".
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
lateral 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.

3.2 - Electrical connections of MC824HR control unit

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 present in the automation.
– Connections must be made exclusively by qualified personnel.
– The electrical power line must be fitted with a device that enables complete
disconnection of the automation from the mains. The disconnection device
must have a gap between contacts that ensures complete disconnection in
the conditions of overvoltage category III, in compliance with installation regula-
tions. If necessary, this device guarantees rapid and safe disconnection from
the mains, and therefore should be located in view of the automation. However,
if located in a concealed position, it must have a system that blocks against
inadvertent or unauthorised reconnection to prevent all risks. The disconnec-
tion device is not supplied with the product.
01. First connect the electric power cable (fig. 4) and secure by means of the
cable clamp;
02. Then connect the electric cables of motors M1 and M2, observing the
symbols on the label (fig. 5):
