WARNING:
AFTER UNPACKING THE SCREEN WINCH TAKE CARE THAT AFTER RELEASING
THE PACKAGING FOAM FROM THE TRACTION STEEL CABLES, YOU HAVE TO
MOUNT THE PROJECTION SCREEN UNDER THE STEEL CABLES. THIS IN ORDER
TO PREVENT THAT THE STEEL CABLES RAVEL UP INSIDE THE WINCH HOUSING.
BEFORE PROCEEDING WITH ELECTRIC CONNECTION, PLEASE CHECK THAT,
INSIDE THE HOUSING OF THE SCREEN WINCH SYSTEM, BOTH TRACTION STEEL
CABLES ARE WELL POSITIONED IN THE SPLINES OF THE ROLLER TUBE.

ELECTRIC CONNECTION
-
The motor has the possibility to be controlled via the supplied handheld RF remote
control or via wired low voltage contact closures.
-
The motor has a six-core power cable.
NEVER CONNECT THE MAINS TO THE WIRES
WHITE, WHITE-BLACK, WHITE-ORANGE.
-
Once the winch is mounted to the ceiling, connect the wires brown, blue and
yellow/green to the mains, following the scheme shown in Fig. 4A;
The winch is supplied with a safety mechanism (Fig. 4B) with a double security system:
first - this is a mechanic safety system that prevents the steel cable to unroll when the speed
has reached 50 rpm; second – this is an electrical security system that disconnect the
electrical connection of the motor if the force driven on the steel cable, caused by the falling
down, is more than 503 Nm.
5. Take now the beam and position it under the screen winch, taking care that the front
(indicated) of the beam is in the correspondence of the front of screen housing.
Take the steel cables coming out of the screen winch and go through the eyebolt and fix
them
to
the
L-form
bracket,
at
the
beam
as
shown
in
Fig.6.
