6.6) Self-diagnosis Menu (
selftest
)
Allows you to carry out control unit self-diagnosis.
If, at the end of the diagnosis, the answer is OK, it means that the control
unit and connected devices operate correctly.
In case of error, the display indicates the number of the terminal which does
not operate correctly; thus proceed to checking the devices connected to
this, making reference to the following table:
22
Start error
23
Stop error
24
Photocell error
25
Opening limit-switch error
26
Closing limit-switch error
27
Pedestrian input error
28
Open error
29
Close error
30
Electric edge error
31
Clock error
6.7) Autoset Menu (
Autoset
)
Allows you to automatically set the following parameters:
Opening torque
Closing torque
Encoder
Brake
To carry out autosetting, connect two N.O. pushbuttons, if not provided, to
inputs 21-28 (Open) and 21-29 (Close).
WARNING!!
The autoset operation is only to be carried out after checking
the exact leaf (opening/closing) movement, and correct limit-switch
activation.
Therefore, during display of the (.... .... ....) message, carry out about fifteen
opening and closing manoeuvres in
“
Hold-to-run
”
mode, by pressing and
keeping the OPEN or CLOSE pushbutton alternatively pressed until the
opening or closing limit switches are activated.
During this phase, the control panel carries out tests with various levels of
opening/closing torque, encoder sensitivity and brake value.
Moreover, during autosetting, the leaf may be stopped, due to the checks
which are being carried out by the control panel.
After this, if autosetting is successfully completed, the control unit
automatically exits the (.... .... ....) phase, and displays the
“
OK
”
message
which indicates correct autoset execution.
If, on the other hand, the control unit remains in the (.... .... ....) phase after
the 15 expected manoeuvres, it means that there are certain resistance
points along the gate which do not allow the control unit to set optimum
operation values.
Proceed to find out whether there are any mechanical obstructions which
might prevent regular leaf movement.
WARNING!
About 10 manoeuvres are carried out in
“
Hold-to-run
”
mode in
the course of the autoset phase, during which the installer must control the
automation movement and prevent persons or things from approaching or
standing within the automation working range.
WARNING: Check that the impact force value measured at the
points established by the EN 12445 standard is lower than that
specified in the EN 12453 standard.
Incorrect sensitivity setting can cause injuries to persons or
animals, or damage to things.
6.8) Statistics
Having connected the UNIPRO programmer to the control unit, enter the
CONTROL UNIT / STATISTICS menu and scroll the screenful showing the
statistical parameters:
-
Board microprocessor software version.
-
Number of cycles carried out. If motors are replaced, count the number
of manoeuvres carried out up to that time.
-
Number of cycles carried out from the latest maintenance operation.
It is automatically set to zero after each self-diagnosis or parameter writing.
-
Date of latest maintenance operation. To be updated manually from the
appropriate menu
“
Update maintenance date
”
.
-
Installation description. 16 characters can be entered for installation
identification.
7) SERIAL CONNECTION (Fig.5)
The
LEO
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
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
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 safety devices (photocells and sensing edges) should be connected
according to the diagram in Fig. 6b.
The Start, Open, Close, push-buttons and the Timer contact should be
normally connected to the M1 (master) control board.
The pedestrian command is to be connected to the M2 panel (slave).
The Stop command provides greater safety and is generated by a double
contact NC push-button connected to both control boards as shown in Fig. 6b.
NOTE:
Disable the TCA function from the M2 (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.
