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):
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 MC824H

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. 6) . 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 connect-
ed even when the "Stand By" function is activated on the card .

3.4 - Connected device address assignment to MC824H

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
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 MC824H

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  and "Set" keys at the same time (fig. 7) .
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 - Selecting the type of gearmotor connected to MC824H

and learning the mechanical stop positions

After learning the devices (paragraph 3 .6), the type of motors connected must
be selected (see Table 3) and the positions of the mechanical stops must also
be learnt (maximum opening and maximum closing) . 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 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 .
