Connection example: SMS U2 as awning control
Connection example: SMS 1
Installation
The SMS 2 controller monitors 3 adjustable parameters: Wind, shading and twilight. Shading or twilight can also be deactivated individually if required (the
flush-mounted version SMS U2 does not have the twilight function).
For low voltage wiring (shown in green) control or data cables such as I-Y(St)Y 2x2x0.6 can be used (length max. 50m). The low voltage for the sensor supply is
generated directly in SMS 2 (SMS 2. An additional external power supply is not required.
*) If required, a switch can be integrated into the sensor cable to permanently switch off the automatic shading and twilight control.
For SMS U2 (without twilight function) a simple switch is sufficient. For SMS 2 (with twilight function), a changeover switch must be used to switch to a
150kΩ resistor in order to prevent the twilight function from responding.
This type of switch-off only deactivates the sun automation. The safety-relevant wind monitoring remains fully functional.

Please note:
Only one SMS 2 controller (e.g. SMS U2) can be operated on one wind or light sensor.
A single SMS 2 is used as central control for controlling several drives. The respective individual drives are
then operated with the UMS 5, UMS U5 or FE3 M motor controller.
The relay outputs of the central SMS 2 are routed to the auxiliary inputs of UMS 5.
