7) SERIAL CONNECTION (Fig.5)
The LEO-MA control panel allows several automation units to be connected
in a centralised way by means of appropriate serial inputs and outputs. This
makes it possible to use one single command to open and close all the
automation units connected.
Following the diagram in Fig. 5, proceed to connecting all the LEO-MA
control panels, exclusively using a telephone-type line.
Should a telephone cable with more than one pair be needed, it is
indispensable to use wires from the same pair.
The length of the telephone cable between one appliance and the next must
not exceed 250 m.
At this point, each of the LEO-MA control panels must be appropriately
configured, by setting a MASTER unit first of all, which will have control over
all the others, to be necessarily set as SLAVE (see logic menu).
Also set the Zone number (see parameter menu) between 0 and 127.
The zone number allows you to create groups of automation units,
each one answering to the Zone Master unit. Each zone can only be
assigned one Master unit, the Master unit in zone 0 also controls the Slave
units in the other zones.
Loop closing of the serial connection (indicated by a dotted line in Fig.5) is
only needed if you require to check the no. of the connected devices by
means of UNIPRO.
7.1) Opposite sliding leaves (Fig.6)
Serial connection also provides centralized control of two opposite
sliding gates (Fig.6a).
In this case, the Master M1 control board will perform closing and opening
of Slave M2 control board simultaneously.
In case of opposite sliding leaves, the M1 (master) control board and the M2
(slave) control board should bear the same area number without other
devices being connected in such area.
If the opening direction of one of the two motors is incorrect, invert the
connection 6 and 8 of the motor as well as the connections 25 and 26 of
the opening and closing limiting devices.
The unchecked photocells must be connected to the master panel, according
to diagram in fig. 7.
The checked photocells must be connected to the master panel, according
to the diagrams illustrated in fig. 8 and subsequent figures.
The safety edges must be connected to their respective control panel, in all
cases.
For any type of photocell and safety-edge configuration, bridge together
terminals 24 of each control panel. The Start, Open, and Close buttons, and
the Timer contact are normally to be connected to the M1 panel (master).
The pedestrian command is to be connected to the M2 panel (slave).
For greater safety, the Stop command will use a button with double NC
contact connected to both control panels, as indicated in fig. 6b.
NOTE: Disable the TCA (automatic closing time) of the M2 panel (slave).
If the "Photocell test" logic is enabled in the master panel, it must necessarily
be disabled in the slave panel.
8) SCRAPPING
Warning: This operation should only be carried out by qualified
personnel. Materials must be disposed of in conformity with the current
regulations. In case of scrapping, the automation devices do not entail any
particular risks or danger. In case of materials to be recycled, these should be
sorted out by type (electrical components, copper, aluminium, plastic etc.).
9) DISMANTLING
Warning: This operation should only be carried out by qualified
personnel. When the control unit is disassembled to be reassembled on
another site, proceed as follows:
• Disconnect the power supply and the entire electrical installation.
• In the case where some of the components cannot be removed or are
damaged, they must be replaced.
