2) GENERAL OUTLINE
The LIBRA-C-MA control panel is supplied by the manufacturer with standard
setting. Any alteration must be set by means of the incorporated display program-
mer or by means of universal palmtop programmer. The Control unit completely
supports the EELINK protocol.
Its main characteristics are:
-
Control of two low-voltage motors up to 40W power
-
Electronic torque setting with obstacle detection
-
Limit-switch control inputs
-
Separate inputs for safety devices
-
Incorporated rolling-code radio receiver with transmitter cloning
The board is provided with a terminal board which can be pulled out for easier
maintenance or replacement. The board is supplied with a series of pre-wired
jumpers to facilitate the installer's work.
The jumpers relate to the following terminals: 15-17,15-18, 23-24, 23-25, 23-26
and 23-27. If the above-mentioned terminals are in use, remove their respective
jumpers.
CHECK
The LIBRA-C-MA panel carries out a control (check) on the starting relays and safety
devices (photocells) before carrying out each opening and closing cycle.
In case of malfunction, check the devices connected for regular operation and
check the wiring.

When installing the BT-BAT kit, check for correct connection of the safety devices.
When using the BT BAT battery kit, the value of the power supply Faston terminal
~
must be set to 25 V
on the transformer.

WARNING – During the wiring and installation operations, refer to the current
standards as well as principles of good technical practice.
Wires powered at different voltages must be physically separated, or suitably
insulated with at least 1 mm extra insulation. The wires must be clamped by an
extra fastener near the terminals, for example by bands.
All the connection cables must be kept at an adequate distance from the dis-
sipator.
WARNING! For connection to the mains, use a multipolar cable with a minimum
of 3x1.5mm
2
cross section and complying with the previously mentioned
regulations. For connection to the motors, use a cable with a minimum cross
section of 2.5 sq mm, of the type prescribed by current standards.
For example, if the cable is out side (in the open), it has to be at least equal
to H07RN-F, but if it is on the inside (or outside but placed in a plastic cable
cannel) it has to be or at least egual to H05VV-F.

24-25-26-27, provide jumpers between terminals 5-15 and 8-15.
5) PROGRAMMING
The control panel provided with a microprocessor is supplied with function
parameters preset by the manufacturer, suitable for standard installations. The
predefined parameters can be altered by means of either the incorporated display
programmer or universal palmtop programmer.
In the case where programming is carried out by means of universal palmtop
programmer, carefully read the instructions relating to universal palmtop pro-
)
grammer, and proceed in the following way.
Connect the universal palmtop programmer to the control unit through the
UNIFLAT and UNIDA accessories (See fig. 4). The LIBRA-C-MA control unit does
not supply the universal palmtop programmer with power, and therefore requires
an appropriate supply unit.
Enter the "CONTROL UNITS" menu, and the "PARAMETERS" submenu, then scroll
the display screenfuls using the up/down arrows to set the numerical values of
the parameters listed below.
For the function logics, refer to the "LOGIC" submenu.
In the case where programming is carried out by means of the incorporated
programmer, refer to Fig. A and B and to the paragraph on "Configuration".
6) CONFIGURATION
The display programmer is used to set all the LIBRA-C-MA control panel func-
tions.
The programmer is provided with three pushbuttons for menu scrolling and
function parameter configuration:
+
menu scrolling/value increment key
-
menu scrolling/value reduction key
OK Enter (confirm) key
The simultaneous pressure of the + and - keys is used to exit the active menu and
move to the preceding menu.
The modifications made are only set if the OK key is subsequently pressed.
When the OK key is pressed for the first time, the programming mode is en-
tered.
The following pieces of information appear on the display at first:
-
Control unit software version
-
Number of total manoeuvres carried out (the value is expressed in thousands,
therefore the display constantly shows 0000 during the first thousand ma-
noeuvres)
-
Number of manoeuvres carried out since the latest maintenance operation
(the value is expressed in thousands, therefore the display constantly shows
0000 during the first thousand manoeuvres)
-
Number of memorised radio control devices.
When the OK key is pressed during the initial presentation phase, the first menu
can be accessed directly.
Here follows a list of the main menus and the respective submenus available.The
predefined parameter is shown between square brackets [ 0 ].
The writing appearing on the display is indicated between round brackets.
Refer to Figures A and B for the configuration procedure.
