Add Start button (add start)
associates the required key to Start command
Add 2ch button (add 2ch)
associates the required key to 2nd radio channel
- Read (read)
Checks one key of a receiver; if stored it displays a message showing
the receiver number in the memory location (from 01 to 64), and the key
number (T1, T2, T3 or T4).
- Delete (erease 1)
Removes one single key of a transmitter from the receiver memory; after
deletion it displays a message showing the receiver number in the
memory location (from 01 to 64).
- Eliminate list (erease 64)
WARNING! Completely removes all memorised radio control devices
from the receiver memory.
6.4) LANGUAGE MENU (language)
Allows you to set the language on the display programmer.
- ITALIAN (ITA)
- FRENCH (FRA)
- GERMAN (DEU)
- ENGLISH (ENG)
- SPANISH (ESP)
6.5) DEFAULT MENU (default)
Restores the preset default values on the control unit. After restoring, a new
autoset operation must be carried out.
6.6) DIAGNOSTICS AND MONITORING
The display on the LIBRA panel shows some useful information, both
during normal operation and in the case of malfunctions.
Diagnostics:
In the case of malfunctions, the display shows a message indicating which
device needs to be checked:
STRT = START input activation
STOP= STOP input activation
PHOT= PHOT input activation
FLT = FAULT input activation for checked photocells
In the case where an obstacle is found, the LIBRA panel stops the door and
activates a reverse manoeuvre; at the same time the display shows the
“AMP” message.
Monitoring:
During the opening and closing phases, the display shows four digits
separated by a dot, for example 35.40. The digits are constantly updated
during the manoeuvre, and represent the maximum torque reached by
motor 1 (35) and motor 2 (40).
These values allow the torque setting to be corrected.
If the maximum torque value reached during the manoeuvre gets sensibly
close to the value set in the parameter menu, malfunctions may occur in the
future following wear or slight door deformation.
It is therefore advisable to check the maximum torque reached during some
of the manoeuvres carried out in the course of installation, and if necessary
set a value about 15-20 percent points higher in the parameter menu.
6.7) AUTOSET MENU (autoset)
Allows you to automatically set the Motor torque.
WARNING!! The autoset operation is only to be carried out after checking
the exact leaf (opening/closing) movement, and correct limit-switch
activation.
As soon as the OK pushbutton is pressed, the “.... ....” message is
displayed, and the control unit executes an opening manoeuvre followed by
a closing manoeuvre, during which the minimum torque value needed for
leaf movement is automatically set.
During this phase, it is important to avoid obscuring the photocells, as well
as using the START, STOP or PED commands and the display.
After this, if autosetting has been successfully completed, the control unit
displays the “OK” message and, after pressing any key, returns to the
Autoset menu.
If, on the other hand, the control unit displays the “KO” message, it means
that the autoset procedure has not been successfully completed; it is thus
necessary to check the wear condition of the gate and the regular movement
of the leaves before proceeding to a new autoset operation.
WARNING! During the autoset phase, the obstacle detection function is not
active, therefore the installer must control the automation movement and
prevent persons and things from approaching or standing within the
automation working range.
In the case where buffer batteries are used, autosetting must be carried out
with the control panel supplied by mains power voltage.
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 torque 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 USING SCS BOARD (Fig.7)
The LIBRA control panel allows several automation units (SCS) 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.7, proceed to connecting all the LIBRA 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 LIBRA 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.7) is
only needed if you require to check the no. of the connected devices by
means of UNIPRO.
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.
The descriptions and illustrations contained in the present manual
are not binding. The Company reserves the right to make any alterations
deemed appropriate for the technical, manufacturing and commercial
improvement of the product, while leaving the essential product
features unchanged, at any time and without undertaking to update
the present publication.
