a) connect the motor that activates the lower leaf (the second to start the
opening manoeuvre) to terminal M1 and then the respective encoder to
terminals 1-2;
b) connect the motor that activates the upper leaf (the first to start the
opening manoeuvre) to terminal M2 and then the respective encoder to
terminals 4-5;
IMPORTANT! – If there is only one gearmotor in the system, con-
nect it to terminal M2 leaving terminal M1 free;
03. Then connect the electric cables of the various devices present, with refer-
ence to fig. 6 and paragraph 3.3 Note – To facilitate cable connections,
the terminals can be removed from their seats;

3.3 - Connection of other devices to MC824HR

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 (nega-
tive)" (fig. 6). The power supply voltage is 24 Vdc, -30% ÷ +50%, with maxi-
mum available current 200 mA.
Note – The voltage present on terminals "P.P." and "STOP" remains connect-
ed even when the "Stand By" function is activated on the card.

3.4 - Connected device address assignment to MC824HR

To enable control unit recognition of the devices connected to the BlueBus
system, they need to be routed. This operation must be performed by position-
ing the electric jumper correctly on each device; see the relative instruction
manual of individual devices: see fig. A and Table 2.
At the end of the installation procedure or following the removal of photocells
or other devices, the self-learning procedure for these devices must be per-
formed. See paragraph 3.6.

CONFIGURATION NOT ADMITTED

3.5 - 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. 7) flashes regu-
larly with a frequency of about one flash per second.
• Make sure that the LEDs on the photocells (fig. 7) 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
control unit and check the electrical connections previously made.

3.6 - Learning of the devices connected to MC824HR

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
device 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
existing device is removed.
To indicate when the self-learning procedure is required, LEDs L1 and L2 on
the control unit (fig. 7) emit a number of slow flashes:
01. Press and hold down
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).

3.7 - Mechanical limiter position learning

After learning the connected devices (paragraph 3.6), 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 and
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 eight 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 eight leds (L1-L8),
see Table 3.
In combined mode, the automatic procedure can be performed and then,
using the manual procedure, one or more positions may be modified, with the
exception of positions "0" and "1" (fig. B) which coincide with the positions of
the mechanical stops.

3.7.1 - Learning in automatic mode

01. Press and hold keys "Set" and " " 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 (a) does not close the leaf controlled by motor M1 but
closes the one controlled by M2, press key " " or " " to stop the learning
phase. At this point, invert the connections of motors M1 and M2 on the
terminals on the control unit and then those of the respective encoders; after
this start the procedure from point 01;
and "Set" keys at the same time (fig. 7).

L2 Maximum closing position: when leaf 2 reaches closing
mechanical stop
L3 Opening offset: when leaf 2 passes this position the opening
of leaf 1 begins
L4 Desired opening position: position at which the leaf connected
to motor 1 must stop at the end of an opening manoeuvre.
This position does not need to coincide with the opening
mechanical stop but can be chosen as desired between the
positions 0 and 1
L5 Desired opening position: position at which the leaf connected
to motor 2 must stop at the end of an opening manoeuvre.
This position does not need to coincide with the opening
mechanical stop but can be chosen as desired between the
positions 0 and 1
L6 Closing offset: when leaf 1 reaches this position, leaf 2 begins
to close
L7 Maximum opening position: when leaf 1 reaches the opening
mechanical stop
L8 Maximum opening position: when leaf 2 reaches the opening
mechanical stop
