General information
The SMS 2 or SMS U2 are used together with the SW 4 wind
sensor and the SL 2 light sensor for safe and convenient
control of awnings or external blinds.
When the sun intensity is high, the awning is extended auto-
matically, and retracted again when the brightness decrea-
ses (this automatic function can also be deactivated).
If the wind speed is too high, the awning is retracted automa-
tically.
The SMS 2 also has an integrated twilight function and a
blind reverse function.
Buttons for direct OPEN/CLOSE operation can be connec-
ted. The automatic shading system can be deactivated for a
certain period of time by pressing an operating button for a
longer period of time.
Wind monitoring always has priority, so system safety is gua-
ranteed even in the event of incorrect operation.
Applications
Convenient automatic shading control with additional protec-
tion against wind damage to electrically operated awnings.
SMS 2 has an additional automatic twilight function for night-
time room darkening.
Operation
The desired response thresholds are set with the „Sun“ and
„Wind“ (and „Twilight“ at SMS 2) settings.
When a set limit value is exceeded, the control LED starts
ashing and the awning is activated after the response time
has elapsed. The details of the individual operating modes
can be found in the function diagrams.
The awning can also be operated manually by a directly
connected dual push-button (without mutual interlock). The
response time of the automatic shading function is reset
after each manual operation.
In order to manually force the awning to remain stable for a
long period of time, a long press (5 seconds) of the OPEN or
CLOSE button can completely deactivate the sun automation
for 5 hours. Pressing the button during this time reactivates
the automatic sunshade function.

Important: Counter-rotation of the blinds must be deactiva-
ted!
The automatic wind control always remains active and
always works with absolute priority. This means that the
system cannot be endangered by excessive wind - even in
the event of accidental incorrect operation.
The reaction time in the event of wind is pre-programmed
and is 1 - 15 seconds, depending on the amount of excess
wind. The response time when reaching sun light intensitiy
threshold can be individually adjusted by a simple program-
ming procedure (factory setting 10 min.).
The motor running time can also be programmed for individu-
al adaptation to the awning used (factory setting 90s).
If the SMS 2 or SMS U2 is used as group control, this can
also be set in a programming process. In this case, the
controller only releases the outputs as soon as the wind level
falls below the set limit value.

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
ush-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 sufcient. 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.

Application example: SMS 2 in combination with GSR 2 (limit switch for rain) as central control for
light, wind and rain monitoring
For rain monitoring, the limit switch GSR 2 is connected to the control‘s auxiliary inputs OPEN (NA) in addition to SMS 2. Auxiliary input OPEN (NA) has the highest priority. Opposing controls are therefore safely overruled by the GSR 2.
Please note: Only one sensor control or one limit switch can be operated on one associated sensor at a time! A sensor control and (or) a limit switch are 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 control are routed to the auxiliary inputs (NA and NZ) of the individual controls. 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 the respective controller. An additional external power supply is therefore not required.

Conguration and commissioning
1) Press and hold the OPEN and CLOSE inputs at the same time for 10 seconds
This activates programming mode with the programming process.
Restoring factory default settings:
If the controller is accidentally miscongured, this can be corrected by restoring the factory default settings.
To do this, press the OPEN and CLOSE buttons at the same time for 20 seconds until the LED blinks green and red (on the
SMS 2, all LEDs will blink).
Factory default settings
After 30 seconds in setting mode with no button press, setting mode is exited automatically and all set-
tings made up to that point are accepted.
ÌTerminal 14 retracts or raises the awning (OPEN button)
ÌTerminal 24 extends or lowers the awning (CLOSE button)
Info
Step 1: Adjust the response time for shading (and for twilight with SMS 2)
(SMS U2: LED lit green / SMS 2: LEDs B and D lit red)
The factory default response time is 10 minutes. This can be increased incrementally by pressing the OPEN button or de-
creased incrementally by pressing the CLOSE button. To skip this setting, go directly to Step 2.
One button press corresponds to 1 minute response time
(Setting range: 1–60 min)
2) Briey press the OPEN and CLOSE buttons at the same time
This takes you to the second programming step and saves any previous settings you have made.
Step 2: Adjust the motor run time
(SMS U2: LED lit red / SMS 2: LED W lit red)
The factory default motor run time is 90 seconds. If the awning should only be extended to a specic position in automatic
mode, all you have to do here is to extend it to this position by pressing the OPEN or CLOSE buttons. To skip this setting, go
directly to Step 3.
(Setting range: 1–240 s)
3) Briey press the OPEN and CLOSE buttons at the same time
This takes you to the third programming step and saves any previous settings you have made.
Attention! Note: The awning must be in the home position (fully retracted) for this.
The following default values are congured in the factory:
- Response time for sun exposure: 10min
- Motor run time: 90s
- Group mode disabled
First congure the threshold values and sensor type using the corresponding controls (see “Controls and indicators”). The
following settings only have to be congured if the factory default settings are not suitable (see “Factory default settings”).
Step 3: Enable or disable group mode
(SMS U2: LED lit red-green / SMS 2: LEDs B, D and W lit red)
Group mode is disabled by default (factory setting). Press the OPEN button to enable group mode, or press the CLOSE
button to disable group mode.
4) Briey press the OPEN and CLOSE buttons at the same time
This exits programming mode and saves any previous settings you have made.

The local inputs „OPEN“ (A) or „CLOSE“ (Z) are edge-cont-
rolled and react with the falling edge.
A tuv=0.6s pause when switching between 14 and 24 serves
to protect the awning motor.
The automatic shading system can be completely deactiva-
ted for 5 hours by pressing the button (A or Z) for 5 seconds.
After this time has elapsed (or previously by pressing the
awning again), the automatic system is reactivated.
Info: Counter-rotation of the blinds must be deactivated!
Blind counter-rotation function (SMS 2 only):
Local inputs are level-controlled when the button is pressed
briey and edge-controlled when the button is pressed long.
Countercurrent pulse (tg) is triggered during shading (see
running time diagram for sun) or by manual stop with A or Z.

When the wind speed (frequency of the wind sensor pulse signal W) rises above the set threshold level, the local OPEN (A) and
CLOSE (Z) inputs are completely blocked. The light sensor (S) also has no effect on the controller under this condition. The
inputs are enabled again after the wind speed drops below the set threshold level.
The SMS 2 dynamically adjusts the response delay for wind „ton“ (that means the higher the wind speed overstepping, the
shorter the response time).
