1Functional Characteristic
The switching/blind actuator is a freely configurable relay unit. The basic usage areas are on/off
switching for lightning systems and blind/shutter mechanisms (awnings, blinds, shutters and
various sun and visibility protection devices) used in homes, theaters and all other buildings. The
module can be configurable per one channel according to usage mechanism. One channel can be
configured for on/off or blind/shutter mechanism. The module have the switching capacity of 16A
with high-inrush current capability.
Each channel of these switching actuators has a LED which indicates its switching status and a
manual switch with the settings ON/OFF for switch actuator and UP/DOWN for blind actuators.
A mains connection is required for operation of the manual switches, but the bus voltage does not
need to be present.
Features which can be adjusted via parameter settings including the basic functions of
“Switching”, “On/Off Delay", “Pulse”, “Staircase” for switching actuator and “Blind”, “Shutter”
for blind actuator. In addition, the following can be parameterized for each channel: Input logic,
type of contact (NC/NO) and participation in central commands such as continuous ON,
continuous OFF, central switching and access/recall scene for switching actuators and central
up/down for blind/shutter actuators. 3 safety objects (Safety1, Safety2 and Safety3) can be used to
drive sun and visibility protection devices to a defined position (e.g. during a storm or when it is
raining).
Features of the switching actuators
Manual control for each channel.
Status LED for each channel.
High switching capacity (16A with high-inrush current capacity).
4 different channel functions can be selected:
- Switching
- ON/OFF Delay
- Pulse function
- Staircase light timer with switch-off pre-warning.
Possible integration of the channels into a maximum of 8 scenes.
Adjustable response to bus failure and restoration of the bus/mains power.
Logical functions.

Features of the blind/shutter actuators
On-site operation possible on the device (e.g. for installation testing), drives also possible
without a bus voltage.
LED output status indicators.
Central UP/DOWN object.
3 safety objects and function.
Possible integration of the channels into a maximum of 8 scenes.
Flexible reaction to safety telegrams: individually adjustable for each drive for start and end
of the safety status.
Adjustable response to bus failure and restoration of the bus / mains power.

3Before Operation
3.1 Connection
Every output (C1, C2, C3 …..) can be used separately for switching or for blind/shutter control in pair.
(C1-C2, C3-C4…….). Belobe figure shows possible connections.
1. Status leds for output channels: When led is on the output channel is on. When led is off output
channel is off.
Channel ON = Relay contact is CLOSE
Channel OFF = Relay contact is OPEN
2. Control button for output channels: Allows control output channels manually.
3. Manual button and led: When led is on only manual control is allowed. Device does not response to
bus commands.
4. Set physical address button and led: KNX programming button and led.
5. Lock for upper and lower modules: The device consists of two parts. Lower part which has relays and
upper part which runs application. KNX application is loaded to upper part of the device. Upper part
can be removed with unlock all switches (5).

3.2 Device behaviour after ETS download
Switchin Function: If output channel is configured as switching after ETS download related channel will be off.
Status led will also be off. If manual control is activated from ETS output channels can be controlled via
control buttons on device.
Blind/Shutter Function: If output channel pair is configured as Blind/Shutter after ETS download related
channels will be off. Status leds will also be off. Blind/Shutter will stay on current possion. If manual control is
activated from ETS output channels can be controlled via control buttons on device. For blind/shutter

3.3 Device behaviour after bus failer
This can be configured from ETS for every channel. Switchin and blind/shutter configuration has different
behaviour options.
3.4 Device behaviour after mains failer

Object 0 “Switch ON/OFF”
This object is the actual input object for each channel of the module. It is a 1-bit object for
controlling one output .
Object 1 “Feedback”
This is a 1-bit output object of each channel of the module. This object returns the switching status
of the channel.
Object 2 “Or” / “And” / “Lock” / “Override”
This is a 1-bit object for the input of the logic operation of an output. Any of them appears
according to logic function parameter on the channel paramater page.
Object 108 “Access/Save scene”
This object can be used to save and subsequently recall "Scenes". The save process stores the status
of the channel, regardless of how the status was brought about (e.g. via switching commands,
central objects or the manual switches). The saved status is re-established when it is recalled. Each
channel can participate in a maximum of 8 scenes.

Object 109 “Central continuous ON”
This object is a central object. It can be configured to be effective on all channels. If this object is
set to "1" then all of the channels "participating" in this object are switched on. If this object is set
to "0" then it has no effect on the channels, but the participating channels return back to their last
switching states.
Object 110 “ Central continuous OFF”
This object is a central object. It can be configured to be effective on all channels. If this object is
set to "1" then all of the channels "participating" in this object are switched off. If this object is set
to "0" then it has no effect on the channels, but the participating channels return back to their last
switching states.
Object 111 “Central Switching”
This object is a central object. It can be configured to be effective on all channels. If a "1" or "0" is
sent to this object then this is the same as if a "1" or "0" is sent to the switching objects of the
channels (Object 0, Object 5, Object 10 ...). The same functionality could also be achieved by
connecting all switching objects to the same group as that of this object. Accordingly, using this
object saves time during the assignment of the group addresses and also saves on the number of
assignments.
Object 116 “Centralized feedback”
This object is 4-byte object for reading all channel switching states of the switching modul. The
centralized feedback function groups the switching states of all outputs together in only one
telegram. Byte1 and Byte2 contains the switching states ( S bits) of the corresponding channels.
Byte3 and Byte4 contains the masking bits (M btis) that specify if there is such an output on the
actuator by its value “1”.

4.1.2.3 On/Off Delay Function and Parameters
Basic functionality: If the Function parameter is On/Off Delay, then the channel works for On/Off
delay function. If the channel is switched off and a "1" is sent to the switching object then the switch-
on delay time starts. The switch-on takes place once the switch-on delay time has elapsed. If the
channel is switched on and a "0" is sent to the switching object then the switch-off delay time starts.
The switch-off takes place once the switch-off delay has elapsed. If while a delay time is running the
inverse status is sent then the delay time stops. There is then no switchover. If while a delay time is
running the same status is sent again then this has no effect on the current delay time.

4.1.2.4 Pulse Function and Parameters
Basic functionality: If the Function parameter is Pulse, then the channel works for Pulse function.
A "1" on the switching object switches the channel ON for the duration of a pulse length. If a "1" is
sent again during this switch-on phase then the channel remains switched on for the duration of a
further pulse length. If a "0" is sent during this switch-on phase then the channel switches off
immediately.

4.1.2.5 Staircase light timer with pre-warning Function and Parameters
Basic functionality: A "1" on the switching object switches the channel on for the duration of the
staircase light time. If another "1" is sent during this switch-on time then a further staircase light time
is added to the staircase light time which is already running. If a "0" is sent during this switch-on phase
then the channel switches off after a 30-second pre-warning. The light flickers briefly at the start of the
pre-warning period.
