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.
