LINKING SOMFY MOTORS TO HOME AUTOMATION SYSTEMS OR BUILDING MANAGEMENT SYSTEMS
IMPORTANT NOTE: STANDARD SOMFY MOTORS SHOULD NEVER BE WIRED IN PARALLEL. HARD WIRED CONFIGURATIONS There are several hard-wired methods used to connect Somfy motors to Home Automation Systems (HAS) or Building Management Systems (BMS). The most common method is through an electronic Somfy controller or directly connecting to a HAS/BMS providing that the system has an Interlocking Feature and Individual Outputs for every motor. Interlocking means that when an up or down direction is activated the opposite direction cannot be physically switched or is disabled. The interlocking and Individual Outputs features are critical to this type of installation. If they cannot be achieved do not use this method of installation The CD4 Controller is a Somfy single motor controller (relay) that requires its own 240 V power supply, with an output voltage of 240V A/C (latched). The switching consists of multiple Dry contact impulse switching (impulse contact closure of one second minimum). Contact closure between Common and Up or Down will activate the motor in the appropriate direction and a contact closure between all three contacts Common, Up and Down will create a Stop Command. The CD4 can also be used to control a group of motors through a Somfy Group Motor Controller (3GMC or 4GMC). CD4S may be connected together for multiple switching applications via Busline. This allows for an Individual control from a dedicated switch and for the control of all CD4S from a master switch / controller. Moduline Controllers require its own 240 V power supply. The ML 9000 is a master controller and must be used in every Moduline configuration. The ML 9000 provides the power for the control circuitry to a ML 8000 individual controller (1 X ML 9000 can power up to 16 X ML 8000s). Both ML 9000 and ML 8000 utilise Dry contact impulse switching (impulse contact closure of one second minimum) and can be controlled by the HAS/BMS in this way. Contact closure between Common and Up or Down will activate the motor in the appropriate direction and a contact closure between all three contacts Common, Up and Down will create a Stop Command. The ILT Motor requires its own 240 Volt power supply and has a built-in Flat 4 Point control cable (male phone plug RJ9) that can be easily connected to most HAS/BMS when used in conjunction with a Somfy Phone Plug Connector. The HAS/BMS must be capable of Dry contact impulse switching (impulse contact closure of one second minimum). Contact closure between Common and Up or Down will activate the motor in the appropriate direction and a contact closure between all three contacts Common, Up and Down will create a Stop Command.
Direct 240V Switching should only ever be used in conjunction with Standard Somfy motors. This method of connection is only used when the HAS/BMS is going to be the only source of control, has the ability to interlock between the up and down commands and provide Individual Outputs for every motor. These features are critical to this type of installation and if they cannot be achieved do not use this method of installation. Interlocking means that when an up or down direction is activated the opposite direction cannot be physically switched or is disabled. The HAS/BMS must switch 240V to the up or down directional wires to drive the motor and 0V to stop the motor. In a scenario with multiple motors each motor will require its own individual connection to the HAS/BMS. IMPORTANT NOTE: If both up and down are activated at the same time this will cause unrepairable permanent damage to the motor. RTS CONFIGURATIONS There is only one method of interfacing RTS configurations with HAS/BMS and that by using a Somfy Busline Transmitter. This Transmitter requires its own 240V power supply and has Dry contact impulse switching inputs that connect to the HAS/BMS (impulse contact closure of 5 to 10 seconds minimum). Once powered the Busline Transmitter can be programmed to internal or external Somfy RTS Receivers that control the Somfy motor. For individual control use one Busline Transmitter per RTS Receiver and for group control use one Busline Transmitter per group. IMPORTANT NOTE: If two or more Busline Transmitters are activated at the same time the sent command will not work (the radio signals cancel each other out).

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.
