09. Drill the leaf and fix the bracket using suitable screws (not supplied) (figs.
7-8, 7-9 and 7-10);
10. Before locking the gearmotor, adjust the mechanical opening limiter as
required (paragraph 3.5).
3.5 - Adjusting the mechanical opening limiter
01. Manually move the gate leafs to the maximum opening position;
02. Rotate the plastic disk on the lower section of the gearmotor, to position
the aperture under the arm as shown in fig. 8;
03. Insert the limiter in the first possible place: try to insert as shown in fig. 8
(opening direction);
04. Rotate the disk to prevent the limiter from dropping, moving the aperture to
the position shown in fig. 8; for more precise adjustments, use the adjust-
ment screw (fig. 8);
05. If there is no floor-mounted stop in the system, this procedure must be
repeated from point 01 also for the closing limiter;
06. Lastly, tighten the disk fixing nut fully down (fig. 8) to ensure that it does not
rotate accidentally.

3.6 - Manually releasing and locking the gearmotor

The gearmotor is equipped with a mechanical locking system to enable manu-
al opening and closing of the gate.
These manual operations should only be performed in the event of a power fail-
ure, malfunctions or during the installation procedures.
Releasing (fig. 9):
01. Insert the key;
02. Turn the key anti-clockwise (180°);
03. At this point the leaf can be moved manually to the required position.
Locking (fig. 10):
01. Turn the key clockwise through 180°;
02. Remove the key.

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.
Description of electrical connections (fig. 11)
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. [*]
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 connec-
tion to be used is of the parallel type and no polarity needs to be
observed. During the learning stage, the control unit will recog-
nise individually all devices connected to it thanks to a unique
code. Each time a device is added or eliminated, it will be nec-
essary to make the control unit perform the learning operation
(see paragraph 4.5).
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;
– 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
parallel. If there are more than 2 devices, they must be connect-
ed 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 control devices, which intervene to cause partial open-
ing 1 manoeuvre; possibility of connecting NO type contacts
M output for gearmotor without control unit (HO7224)
[*] The outputs FLASH and ELS can be programmed with other functions
(see "TABLE 5 – Level 1 functions"; or via the Oview programmer; see para-
graph 8.3).

4.1 - Gearmotor electrical connections

Caution! – Only make the electrical connections after installing the
gearmotor.
WARNINGS!
– Connections must be made exclusively by qualified personnel.
– All electrical connections must be made with the unit disconnected
from the mains power supply and with the buffer battery disconnected
(if present).
– The electrical power line must be fitted with a device that enables com-
plete disconnection of the automation from the mains. The disconnection
device must have a gap between contacts that ensures complete discon-
nection in the conditions of overvoltage category III, in compliance with
installation regulations.
01. Open the cover of the gearmotor (fig. 12-1);
02. Route the power cable and other electric cables through the hole on the
lower section of the gearmotor (afb. 12-2);
03. First connect the power cable of the motor with the control unit HO7124:
loosen the cable clamp (fig. 12-3) and connect the power cable as shown in
fig. 12-4; then secure the cable by means of the cable clamp (fig. 12-5);
04. Then connect the cable powering the motor without control unit (HO7224) as
shown in fig. 13;
05. Lastly connect the electric cables of the various devices present, with reference
to fig. 11 and paragraph 4.3. Note – To facilitate cable connections, the termi-
nals can be removed from their seats;
06. In the Table 2 identify the type corresponding to the system to be pro-
grammed and if necessary, on the control unit, set the selector JA and
jumper JB as described;
07. Close the gearmotor cover (fig. 12-6).

4.2 - Connection of other devices

If further devices present in the system need to be powered, for example a
transponder card reader or the key selector light, these devices can be con-
nected to the control unit using terminals "P.P. (positive)" and "STOP (negative)"
(fig. 11). The power supply voltage is 24 Vdc, -30% ÷ +50%, with maximum
available current 200 mA.
Note – The voltage present on terminals "P.P." and "STOP" remains connected
even when the "Stand By" function is activated on the card.

4.3 -Routing connected devices

To enable control unit recognition of the devices connected to the BlueBus sys-
tem, they need to be routed. This operation must be performed by positioning
