of individual devices: see fig. A and Table 3.
To route other devices, consult the relative instruction manuals. At the end of
the installation procedure, or after removing photocells or other devices, the
device learning procedure must be performed as described in paragraph 4.5.

CONFIGURATION NOT ADMITTED

4.4 - Initial start-up and electrical connections

After powering up the control unit, perform the following checks:
• After a few seconds, make sure that the "Bluebus" LED (fig. 15) flashes regu-
larly with a frequency of about one flash per second.
• Make sure that the LEDs on the photocells (fig. 15) flash (both on TX and RX).
The type of flashing is not important during this stage.
• Make sure that the flashing light connected to the FLASH output is off.
If the above conditions are not satisfied, switch off the power supply to the con-
trol unit and check the electrical connections previously made.
4.5 - Learning of the devices connected
After the initial power-up, the control unit must be able to recognise the devices
connected to the "Bluebus" and "Stop" inputs.
IMPORTANT ! – The learning procedure must be performed even if no de-
vice is connected to the control unit.
The control unit is able to recognise the various connected devices individually
through the self-learning procedure and detect possible faults. For this reason it
is necessary to perform self-learning every time a new device is added or an ex-
isting device is removed.
To indicate when the self-learning procedure is required, LEDs L1 and L2 on the
control unit (fig. 15) emit a number of slow flashes:
01. Press and hold down  and "Set" keys at the same time (fig. 15).
02. Release the keys when LEDs L1 and L2 start flashing quickly (after approx.
3 seconds).
03. Wait a few seconds for the control unit to complete the device learning
phase.
04. At the end of this phase, the "Stop" LED must be lit and LEDs "L1" and
"L2" must be turned off (LEDs L3 and L4 may start flashing).

4.6 - Learning the mechanical stop positions

After learning the connected devices (paragraph 4.6), the positions of the
mechanical stops must also be learnt (maximum opening and maximum clos-

ing). There are three ways to perform this procedure: automatic, manual or
combined.
In automatic mode, the control unit learns the positions of the mechanical
stops and calculates the most suitable offset value for the leafs (SA and SC,
fig. B).
In manual mode, the six positions of the mechanical stops fig. B are pro-
grammed one by one, moving the leafs to the required points. The position to
program is identifiable by the flashing status of one of the 6 leds (L1-L6), see
Table 4.
In combined mode, the automatic procedure can be performed and then, using
the manual procedure, one or more positions may be modified, with the excep-
tion of positions "0" and "1" (fig. B) which coincide with the positions of the
mechanical stops.

4.6.1 - Learning in automatic mode
01. Press and hold keys "Set" and "u"at the same time;
02. Release the keys when leds "L3" and "L4" start flashing quickly (after
approx. 3 seconds);
03. Ensure that the automation completes the following sequences of ma -
noeuvres:
a - Low speed closure of gearmotor M1 through to the mechanical stop
b - Low speed closure of gearmotor M2 through to the mechanical stop
c - low speed opening of gearmotor M2 and gearmotor M1 through to the
mechanical stop
d - High speed closure of gearmotors M1 and M2
– If the first manoeuvre performed by one or both the leafs is not closing, press
"" or "u" to stop the learning phase; then check the position of selector JA
and jumper JB (see Table 2) or check connection polarity of the motor with-
out control unit (HO7224).
– If the first closing manoeuvre is not controlled by M1, press "" or "u" to
stop the learning phase; then check the position of selector JA and jumper
JB, see Table 2;
04. At the end of the Closing manoeuvre of the 2 motors (d), leds "L3" and
"L4" turn off to indicate the that the procedure has been completed cor-
rectly.
– During the automatic learning procedure, if a photocell trips or a device con-
nected to the "stop" input is activated, the procedure is interrupted and led
L1 starts flashing. To resume the learning process, the procedure must be
started again from point 01;
– The automatic learning procedure can be repeated at any time, also after
installation; for example following modifications to the position of the
mechanical stops.
4.6.2 - Learning in manual mode
Caution! – From step 03 onwards:
– to move from led L1 to L6, briefly press key  or u (the led flashes to indi-
cate the current position);
– to move the motor in one or the other direction, press and hold key  or u.
01. Press and hold keys "Set" and "u" at the same time.
02. Release the keys when led "L1" starts flashing (after approx. 1 second);
Note – After 3 seconds have elapsed, if the keys "Set" and "u" are not re-
leased, the "automatic learning" procedure is started up, and not the man-
ual procedure.
