Schalk SMS 1 User manual
General information
The SMS 1 or SMS U1 is used with the SWL 2 combined
wind and light sensor for reliable and convenient control of
awnings or external louver blinds.
The awning is automatically extended under bright sunlight
conditions and retracted when brightness decreases.
The awning is automatically retracted under high wind con-
ditions.
The SMS 1 additionally has an integrated twilight function
and supports a choice of sensors.
Push-buttons for direct open/close operation can be con-
nected. The automatic twilight function can be disabled for a
specic interval by a long button press.
Wind monitoring always takes priority to provide reliable
protection against user errors.
Applications
Convenient automatic shading control with additional protec-
tion against wind damage to electrically operated awnings.
SMS 1 has an additional automatic twilight function for night-
time room darkening.
Operation
The desired trigger thresholds are set by conguring the Sun
and Wind settings (and Twilight with the SMS 1). The con-
nected light sensor type can also be selected with the SMS
1. Relay outputs can also be congured separately for pulse
output (2 s) or continuous output for the duration of the set
motor run time (LZ).
When a set limit value is exceeded, the indicator LED starts
to blink and the awning is actuated at the end of the res-
ponse time. See the functional diagrams for details of the
individual operation modes.
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.

To manually compel a longer stable awning state, the au-
tomatic sunlight function can be completely disabled for 5
hours by pressing the Open or Close button for 5 seconds.
Pressing a button during this period re-enables the automa-
tic sunlight function.
The automatic wind function is always enabled and always
overrides all other functions. This avoids the risk of damage
to the awning system from strong wind, even in the event of
accidental user error.
The response time for wind is preset and amounts to 1 to 15
seconds, depending on how much the wind speed exceeds
the threshold value. The response time for sun exposure can
be individually adjusted using a simple programming process
(factory default setting: 10 minutes).
The motor run time can also be programmed to match the
individual awning (factory default setting: 90 seconds).
When the SMS 1 or SMS U1 is used as a group controller,
this can also be set in a programming process. In this case
the controller freezes the outputs until the wind level drops
below the set limit value.
Controls and indicators
Light intensity threshold setting
Setting range 20,000 –100,000 lx
Sensor type setting (SMS 1 only)
SWL 2 = combined wind and light sensor
SL 1 = light sensor
SW 2 = wind sensor (anemometer)
In the “2s” position the SMS 1 generates a 2-second control
pulse on the relay output, which for example can be used to
actuate lower-level controllers.
In the “Hold” position the programmed motor run times (see
functional diagrams) apply.
Status indicator LEDs:
SMS U1: A blinking red LED ( ) indicates wind speed above
the threshold level; blinking green ( ) indicates brightness
above the threshold level.
SMS 1: Blinking red ( ) with LED W indicates wind speed
above the threshold level, with LED B light level above the
brightness threshold, and with LED D light level below the
twilight threshold.
LEDs 14 and 24 indicate the corresponding motion direction.

Conguration and commissioning
1) Press and hold the Open and Close inputs at the same time for 10 seconds
This activates programming mode with the three-step programming process.
Restoring factory default settings:
If the controller is accidentally miscongured, 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
1, all LEDs will blink).
Factorydefaultsettings
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 1)
(SMS U1: LED lit green / SMS 1: 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 decre-
ased 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) Briey 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 U1: LED lit red / SMS 1: LED W lit red)
The factory default motor run time is 90 seconds. If the awning should only be extended to a specic 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) Briey 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 congured in the factory:
- Response time for sun exposure: 10 min
- Motor run time: 90 s
First congure the threshold values and sensor type (SMS 1) using the corresponding controls (see “Controls and indicators”).
The following settings only have to be congured if the factory default settings are not suitable (see “Factory default set-
tings”).
Step 3: Enable or disable group mode
(SMS U1: LED lit red-green / SMS 1: 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) Briey press the Open and Close buttons at the same time
This exits programming mode and saves any previous settings you have made.

Functional diagrams
The local Open and Close inputs are edge-triggered and respond to the falling edge of the signal:
When the wind speed (frequency of the wind sensor pulse signal W) rises above the set threshold level, the local Open and
Close inputs are completely blocked. The light sensor 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:
To protect the awning motor, there is a dead time tUV of 0.6 second for switching between K14 and K24:
If you wish to disable the automatic shading function, simply press and hold one of the control buttons for 5 seconds. This will
fully disable the automatic sunlight function for 5 hours. It is enabled again at the end of this period, or earlier if the is awning
is moved.
