Motorisation of Window Coverings
using Somfy Motors
Wiring Considerations
LS40 and LT 50 Motors
Problem
When the switch is turned to either the up or the down position, both motors will turn
together.
One of the motors (A) will stop at its pre-set limit before the other (B).
Current from motor (B) will then flow back through to motor (A) through capacitor
C2 and micro-switches M3 and M1.
There will be constant feedback from one motor to the other causing the motors to
continuously change direction, but with very little travel.
The motors will eventually burn out.
Solution
For one of more motors use a Somfy group controller.
