Installation - V2 LEX-FE Handbuch

INSTALLATION

• Fix the stirrup G to the wall.
• Insert the crown A in the driving wheel B of the limit switch
(fig.1).
• Insert the pulley C on the pivot of the motor D (fig.1).
Insert the copper pin F on the pulley C.
•
• Insert completely the motor in the roll-tube (fig.2).
• Fix the roll-tube to the driving wheel with m 4 x10 screw (fig.2).
DESCRIPTION
LEX-FE opening system is made up of a tubular motor with built-in
control unit.
• Possibility to control the awning/roller shutter by two buttons
(type N.O., any series or model)
• Programming is made by two N.O. buttons
• Hall effect position sensor for a perfect adjustment of the limit
switches
• Obstacle detection during the closing phase of the roller
shutter with instant stop of the motor
INSTALLATION
Once fixed the motor inside the winding tube, make the electrical
connections following the diagram on the first page taking into
consideration the following point:
• The two operating n.o. push buttons must not be replaced by
a switch without self-return to n.o. position; this appliance is
not intended to be permanently connected to the mains.
If the application requires a permanent connection to the
mains use another product of the LEX range (SCREEN
catalogue)
• The two cables (brown and black) are the electric OPENING
and CLOSING phases of the motor. If the motor does not
rotate in the desired direction, reverse the brown and black
cables wired to the two buttons.
PROGRAMMING OF THE LIMIT
SWITCHES
LEX-FE tubular motors are provided with an electronic limit switch
cutting off power supply when the awning/roller shutter reaches
the UPPER or LOWER end of stroke.
To programme the position of the limit switches proceed as
follows, choosing at point 1 the option AWNING or ROLLER
SHUTTER.
NOTE: the option AWNING automatically sets a short phase of
inversion after the stop subsequent to a closing phase: this to
allow the fabric of the awning to loose.
UPPER
POSITION
LOWER
POSITION
1. AWNING: press and keep pressed both the buttons for at
least 4 seconds until the motor moves in both the directions,
indicating it has entered programming mode.
ROLLER SHUTTER: press and keep pressed both the buttons
for at least 4 seconds until the motor moves in both the
directions indicating in has entered programming mode; keep
pressed for 2 more seconds until the motor moves again in
both the directions.
2. Release the buttons
3. Take the roller shutter to the desired upper position.
WARNING: If automating a cassette awning, let the motor
fully wind the awning and stop unattended by activating the
amperometric, storing automatically the closing position.
Go then to point 5.
4. Press the buttons (OPENING and CLOSING) at the same time
until the motor moves in both the directions indicating the
correct programming of the upper position.
5. Take the roller shutter to the desired lower position
6. Press the two buttons (OPENING and CLOSING) at the same
time until the motor moves in both the directions indicating
the correct programming of the lower position.
7. Once stored the lower position, the system automatically exits
programming mode and is ready for use.
RESET OF THE LIMIT SWITCHES
To reset the position of the limit switches proceed as follows:
1. Press and keep pressed both the buttons for at least
30 seconds until the motor moves in both the directions,
2. Release the push-buttons: the position of the limit switches
has been cancelled; repeat the procedure "PROGRAMMING
OF THE LIMIT SWITCHES"
WORKING TIME OF MOTOR
The control unit stops the motor movement after 5 minutes: in
case of limit switches malfunction this "time out" avoids the
motor overheating.
