BFT LIBRA-C-LX Instructions D'installation page 15

3) GENERAL OUTLINE
The LIBRA-C-LX control panel is supplied by the manufacturer with standard setting.
Any alteration must be set by means of the incorporated display programmer or by
means of universal palmtop programmer. The Control unit completely supports the
EELINK protocol.
Its main characteristics are:
- Control of two Lux BT or Lux g BT motors
Note: 2 motors of the same type must be used.
- Electronic torque control with obstacle detection
- Encoder 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 main-
tenance 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, 24-27. If the above-
mentioned terminals are in use, remove their respective jumpers.
CHECK
The LIBRA-C-LX 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.

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 1.5 sq mm 2 , 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.

messages relating to motor 2 will be displayed ("OP 2" e "CL 2").
12) AUTOSET MENU Fig. G
Allows you to automatically set the Motor torque.
WARNING!! The autosetting operation is only to be carried out after checking the
exact leaf movement (opening/closing) and correct limit switch activation.
You are advised to carry out an autosetting procedure each time you modify the
slow-down speed or space.
WARNING! During the autoset phase, the obstacle detection function is not
active, therefore the installer must control the automation movement and pre-
vent 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: The torque values fixed by means of the autoset procedure
refer to the slow-down speed fixed during the same procedure. If the
slow-down speed or space is modified, a new autosetting manoeuvre must
be carried out.
WARNING: Check that the impact force value measured at the
points established by the EN 12445 standard is lower than that speci-
fied in the EN 12453 standard.
Incorrect sensitivity setting can cause injuries to persons or
animals, or damage to things.
