FAAC 541 3ph
The 541 3ph automated system is designed for automat ing balan -
ced industrial sectional doors.
They consist of an electro-mechanical operator, with on-board
(541D) inter-connection board, for remote control unit (844T).
Installation is possible either directly on the shaft of the rope-winding
drums, or by chain transmission (optional item) with a reduction
ratio of 1:1.5 or 1:2.
The non-reversing system ensures mechanical locking of the door
when the motor is not operating and, therefore, no lock needs to
be installed; the manual release and the manual opening system
(in models for which it is supplied) make it possible to move the door
in case of a power cut or malfunction.
The 541 3ph automated systems was designed and built for indoor
and outdoor use.
Graph 1 shows with which type of application the 541 3ph can
be installed, considering the maximum force required to manually
move the door F , in daN (1daN = force required to lift 1,02 kg),
and the diameter of the rope-winding drum Dt in millimetres. For
example, if a door can be moved with a force of 108 daN and
the drum diameter is 180 mm, a 541 3ph with chain transmission of
1:1.5 must be installed.
N.B. Force F can be measured with a dynamometer. It is not directly
related to the weight of the door, but to its balance.
