Installation and operating manual
ELECTRONIC SWITCH FOR SUN BLINDS
for flush-mounting
The switches for sun blinds are manufactured in accordance
with the latest technological facts and are subject to
continuous quality controls.
Please read the installation and operating manual carefully
to avoid mistakes and ensure proper functioning.
General description:
The microprocessor controlled sun blind switch can be used to control motor-driven roller blinds
and sun blinds with limit switches (230V / 50Hz motors).
The manual up / down / stop function is activated by simply touching the keys.
By pushing the up / down keys for 3 seconds, an up and a down motion time can be
programmed which is repeated in a 24 hour cycle.
Due to the 50 x 50mm central plate in accordance with DIN 49075, it can be integrated into
almost all common switch programs with the respective intermediate frames.
very simple programming
no clock needs to be set
24 hours automatic function
programming lock
emergency power backup in the
case of power failure
simple formation of groups possible
External inputs: Extension unit operation, formation of groups
All kinds of 230V signal transmitters, such as push buttons, time switches, photoelectric lighting
controllers, wind sensors etc. can be connected to the inputs “Extern ” and “Extern ”. It is
essential to always connect the same L-conductor which is connected to the blind
switch.
It is possible to combine several blind switches to one group by simply connecting the external
inputs in parallel. These groups can then also be controlled centrally via push buttons, time
switches or a blind switch as well (Fig. 2 and 4). As signals which are present for a longer
period of time are also evaluated as a short impulse, no other functions are blocked. For this
reason, it is possible to connect even customary signal transmitters with extended signal
duration (e.g. time switches, shortest switching time usually 1 min.) to these inputs.
Technical data:
Mains voltage:
230V~, +6/-10%, 50Hz
Switching capacity:
max. 750VA
max. motion time:
180s
In the case of a power failure, the performed programming will be saved for max. 60 minutes.
The device, however, must have been in operation for at least 20 minutes while the mains
voltage was available.
Installation and safety instructions:
The blind switch can be installed into all customary flush boxes with Ø 60mm and can be
used with 50x50mmcentral plates in accordance with DIN 49075.
Per blind switch, only one motor may be connected (refer to the motor manufacturer’s
instructions). If more than one motor is connected to the blind switch, use appropriate cut-off
relays.
Always the same phase which is connected to the contact “L” must be connected to the
inputs “Extern ” and “Extern ”. The maximum wire length at these inputs should not
exceed 100m.
Please make sure that there are no persons or objects in the motion range of the blinds.
Regarding electronic tubular motors, refer to the manufacturer’s instructions concerning the
programming line.
Works at the 230V mains supply must only be carried out by a specialist
under consideration of the valid regulations (e.g. DIN-VDE).
All works must only be carried out when the mains voltage is switched off.
If the device is opened or tampered with, the warranty will expire.
Assembly
Help in case of malfunctions:
Error occurred:
Possible causes / measures:
The blinds move into the wrong
direction when the keysand 
are actuated
motor connectors wrong, swap the connectors at the
outputs “Motor ” and “Motor ”
When the blinds are operated via
the external inputs, they move into
the wrong direction
Swap the connectors at the inputs “Extern ” and
“Extern ”
The blind does not move
Due to a previous operation, the blind motor has
become too hot (the thermal protection of the motor
has triggered) –wait for a couple of minutes
No mains voltage available –check fuse
The blind motor is defective - replace
The blind switch is defective - replace
If disturbances from the mains (e.g. switching processes) affect the function of the device
temporarily, a motion which is possibly being carried out is stopped. Afterwards, regular
operation is again possible.
Operation of the blind switch:
Requested function:
What to do:
key (up) or (down)
input “Extern ” or “Extern ”
setting screw “lock / delete programming”
Explanation:
1. Move blind ”Up” or ”Down” 

At a push of the respective key, the motion time is triggered and the
blind moves to its stop position (stop depends on the setting of the
motor’s limit switches).
The maximum motion time is 180 seconds. Then, the drives are de-
energized.
If an automatic function has been programmed beforehand, the
red LED will glow for 5 seconds when the blind is moved. Manual
commands at the arrow keys and always have priority over
the automatic function and signals at the inputs ”Extern ” or
”Extern ”.

Switch signal to the respective input.
2. Stop moving blind

Shortly actuate any key, or 

Apply signal to the opposite input.
This means that a blind moving in this direction can only be
stopped by a signal at ”Extern ”
3. Perform programming
Activate automatic function


At the desired time of day, push e.g. the key (up) until the red
LED blinks (at least 3 seconds).
(Perform the same with key (down) at the desired time of day).
The programming cannot be carried out via the external inputs.
When the key is actuated, the blind starts to move and the LED
glows. As soon as the LED starts to blink, the key can be
released. Now, the movement in the direction which has just been
carried out is saved for this time of day.
The blind will now move into the respective direction every day at
the programmed time.
4. Change a programmed time

The easiest way to change a programmed time is to overwrite it. To
do so, follow the steps in point 3.
The previous automatic time is replaced by the newly
programmed time.
5. Temporarily deactivate the automatic function
(the programmed (up) / (down) times will be
saved)

Push the keys (up) and (down) simultaneously and keep them
pushed for at least 3 seconds until the red LED blinks.
(By pushing them again for 3 seconds, the automatic function can
be restarted.)
When the keys are pushed simultaneously, the red LED glows.
When it has recognized the command, the LED blinks for 5
seconds. The temporary deactivation of the automatic function
always applies to both directions of movement.
6. Lock device against unauthorized programming
change

Permanently turn the setting screw from position “0” to position
“lock”.
Now, the device cannot be programmed. An existent automatic
function will still be carried out.
7. Permanently delete programmed / times
(automatic function is deactivated)

Shortly turn the setting screw from position “0” to position “delete”.
Then, turn it back to position “0”.
8. Check if the automatic function is activated

Shortly actuate the key or 
If the automatic function is programmed and activated, the red
LED glows for 5 seconds when the blind is moved. (The automatic
function may also be deactivated temporarily, see 5.)
