IMPORTANT! – Connections must be made exclusively by qualified per-
sonnel.

3.2 - 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 connected
even when the "Stand By" function is activated on the card.

3.3 - Connected device address assignment to MC824

To enable the control unit to recognise the devices connected to the Bluebus
system, they must be assigned addresses. This operation must be performed
by correctly positioning the electric jumper present in every device. Refer to the
instruction manual for each individual device.
ATTENZIONE! – When assigning addresses to the photocells, the config-
uration shown in PHOTO 3 below is not permitted.

NON-PERMITTED CONFIGURATION
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 3.5.

3.4 - 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. 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 con-
trol unit and check the electrical connections previously made.

3.5 - 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).
3.6 - Selection of type of gearmotor connected to MC824H
and learning of the positions of the mechanical stops
After learning the devices (paragraph 3.5), the control unit must select the con-
nected motor type (see Table 2) and the positions of the mechanical stops
(max. Opening and max. Closing positions). These procedures can be per-
formed in two ways: automatic or manual.
In automatic mode, the control unit performs learning of the mechanical stops and
calculates the most suitable offsets of the leafs (SA and SC in table 3). In manual
mode, the positions are programmed one by one by moving the leafs to the desired
points. It is also possible to perform an automatic procedure and then adjust one or
more positions using the manual procedure if those calculated automatically are not
adequate.

TABLE 2
3.6.1 - Selecting the motor type and learning procedure in automatic
mode:
01. Press and hold down "Set" and
02. Release the keys when LED L1 begins to flash (motor selection: not per-
formed) or when any of the LEDs L1 ... L8 lights up (motor selection:
already performed).
03. Press or keys within 10 seconds to go to the LED corresponding to
the type of gearmotor connected to the control unit (see Table 2);
04. Press and hold down the "Set" key for at least 3 seconds to memorize the
selected gearmotor. After 3 sec. LED L1 starts flashing, then release the
key;
05. Press and hold down "Set" and
06. Release the keys when LEDs L3 and L4 begin to flash quickly (after
approx. 3 seconds);
07. Check that the automation performs the following sequences of manoeu-
vres:
a - Slow closure of gearmotor M1 as far as mechanical stop
b - Slow closure of gearmotor M2 as far as mechanical stop
c - Slow opening of gearmotor M2 and gearmotor M1 as far as mechani-
cal stop
d - Complete fast closure of gearmotors M1 and M2
Note – If the first two manoeuvres (a and b) are not "closure" but "opening"
manoeuvres, press the "open" or "close" keys to stop the self-learning pro-
cedure. Now, on the gearmotor that performed the opening manoeuvre,
invert the polarities of the two wires of the gearmotor (M1: terminals 7 and
9 - M2: terminals 10 and 12) and begin the procedure from point 01.
08. At the end of the closure manoeuvre of the 2 motors (d), the LEDs L3 and
L4 turn off to indicate that the procedure has been completed correctly.

3.6.2 - Selecting the motor type and learning procedure in manual mode:

Using manual learning it is possible to program the automation with all 8 posi-
tions and with the sequence described in Table 3.
Position Led Description
Position 0 L1 Maximum closing position: when leaf 1 reaches closing
(motor 1) mechanical stop
Position 0 L2 Maximum closing position: when leaf 2 reaches closing
(motor 2) mechanical stop
Position SA L3 Opening offset: when leaf 2 passes this position the ope-
(motor 2) ning of leaf 1 begins
Position A L4 Desired opening position: position at which the leaf con-
(motor 1) nected 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 desi-
red between the positions 0 and 1
Position A L5 Desired opening position: position at which the leaf con-
(motor 2) nected 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 desi-
red between the positions 0 and 1
Position SC L6 Closing offset: when leaf 1 reaches this position, leaf 2
(motor 1) begins to close
Position 1 L7 Maximum opening position: when leaf 1 reaches the ope-
(motor 1) ning mechanical stop
Position 1 L8 Maximum opening position: when leaf 2 reaches the ope-
(motor 2) ning mechanical stop
