Functioning Principal
• The motor drives the wheel
• The wheel drives the roller tube
• The roller tube drives the crown
• The crown drives the limit switch within the motor
ATTENTION
Somfy Motors are not waterproof
Do not hose down with water.
All motors mounted externally require covering!

Wiring Considerations
LS40 and LT 50 Motors
Do not wire Somfy motors and controls without first consulting the wiring diagrams.
Determine which of the drown and black wires correspond to the UP and DOWN
direction prior to the final wiring.
Connect the Earth Wire.
Check that the wire size is in accordance to the number and electrical rating of motors
as outlined in local authority guidelines.
Consider climatic conditions such as temperature and humidity when installing Somfy
controllers. Install control boxes indoors, or use waterproof boxes for outdoor
installations.
Do Not use other switches and controls other than those recommended by Somfy.
When using a Somfy control box plug in type, make sure the power supply is
switched off before plugging in.
! Use one switch per motor. Do not wire one motor to several switches without
using the appropriate Somfy electronic control!
Problem
When ‘switch 1’ is turned to the UP position, the motor will turn. When it reaches its
pre-set position, micro-switch “M1’ will open and the motor will stop.
If ‘switch 2’ is then turned to the down position, the motor will turn in the opposite
direction. Micro-switch ‘M1’ will close. This will cause the capacitor to short circuit
through micro-switch ‘M1’ and ‘switch 1’.
This will damage the contacts in the micro-switch.
Solution
Use Somfy CD4 or other Somfy electronic controller

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.
