FTS charts (230v/50hz range motors)
The FTS system is entirely dedicated to sun protection.
•
The selection charts are designed for horizontal shading or on a very slight incline (5 % max).
•
For a different application, please contact a Somfy technician who will study the feasibility of your installation with you (screen at high
incline, vertical system, etc.)
The power of the actuators must be adapted to the solidity of the support structure:
Veranda type light structure: FTS LT50 25/17 only.

Rigid structure: FTS LT50 25/17 (25 m

Note
: The maximum capacity of the end limit cage of the
FTS LT50 25/17 is 46 turns, which allows 11.7 m of fabric to be
coiled on a
∅
70 mm tube.
Beyond a certain width, it is necessary to split the roller
tubes, the load bar and the fabric to avoid heavy flexing of
the system.
The maximum dimensions are given as a guide and will
depend on the mechanical characteristics of the tubes and
the load bar that are used.
