only be performed by an electrician.
DANGER!
Risk to life from live voltage (mains voltage)!
There are unprotected live components within the device.
• VDE regulations and national regulations are to be followed.
• Ensure that all lines to be assembled are free of voltage and take
precautions against accidental switching on.
• Do not use the device if it is damaged.
• Take the device or system out of service and secure it against
unintentional use, if it can be assumed, that risk-free operation is no
longer guaranteed.
The device is only to be used for the intended purpose described in this manual. Any
improper modification or failure to follow the operating instructions voids any and all
warranty and guarantee claims.
After unpacking the device, check it immediately for possible mechanical damage. If it
has been damaged in transport, inform the supplier immediately.
The device may only be used as a fixed-site installation; that means only when assem-
bled and after conclusion of all installation and operational start-up tasks and only in
the surroundings designated for it.

Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.
2.2. Safety notice for automatic functions
WARNING!
Risk of injury from automatically moving components!
Parts of the system can be started by the automatic controls
and be a danger to persons.
• No persons may remain in the travelling range of parts
driven by an electric motor.
• Adhere to the relevant building regulations.
• Ensure that the return path/access to the building is not blocked
if spending time outside the building (danger of being locked out).
• Correctly decommission the system for maintenance and
cleaning work.
If there is a power outage, the system does not work. Therefore, shadings should be
moved to a save position if there are anticipated weather conditions, for example, if
this has not already been done by the automatic function (product protection).
If the power supply is removed, the connected drive switches off. When the power is
restored, the consumer remains switched off until a new movement command is re-
ceived by the actuator.

13 Setting parameters
Actuator KNX R1-B4 compact 16 A • Version: 28.05.2020 • Technical changes and errors excepted.
When switching via the "Switch channel A1" (1) communication object, the light is
switched on or off normally. When switching via the "Channel A1 Staircase lighting
function Start" object (5), the staircase lighting time function is activated. The time
function has priority, i.e. the status triggered by normal switching is overwritten.
6.3.2. Linking
The "Link" menu item only appears if "Use linking functions" is selected in the settings
for the switch function channel: yes’ is selected.
In the logic object ("Channel X link"), various communication objects can be linked with
AND or OR. Z. B. a light can only be switched on if button input active AND twilight ac-
tive.
6.3.3. Switch on and off delay
The menu item only appears if a switch on or switch off delay is selected in the settings
for the switch function channel. The menu item has the same name as the selected
function.
With the switch on and switch off delay, for example, a switch for ventilation device
and light can be used. However, due to the switch on delay, the ventilator does not start
until the light has been on for a few minutes. The switch off delay causes the ventilator
to run after the switch has been pressed again and the light is already off.

14 Setting parameters
Actuator KNX R1-B4 compact 16 A • Version: 28.05.2020 • Technical changes and errors excepted.
Switch on delay
The switch on delay is set with time base and time factor (e.g. 1 min × 4 corresponds
to 4 minutes). In addition, it is determined whether the time span is extended when a
switch on telegram is received again ("can be retriggered", e.g. by pressing the switch
again) and what happens if a switch off telegram arrives from the bus.
Switch off delay
The switch off delay is set with time base and time factor (e.g. 1 min × 4 corresponds
to 4 minutes). In addition, it is determined whether the time span is extended when a
switch off telegram is received again ("can be retriggered", e.g. by pressing the switch
again) and what happens if a switch on telegram arrives from the bus.
6.3.4. Staircase time switch
The menu item only appears if the staircase light function is selected in the settings for
the switch function channel. The staircase light time function ensures, for example,
that light is on for a while and then switches itself off.
With staircase light timer switching, the time base and time factor are used to set how
long the light remains on (e.g. 1 s × 10 corresponds to 10 seconds). In addition, it is de-
termined whether the time span is extended when a switch on telegram is received
again ("can be retriggered", e.g. by pressing the switch again) and what happens if a
switch off telegram arrives from the bus.

15 Setting parameters
Actuator KNX R1-B4 compact 16 A • Version: 28.05.2020 • Technical changes and errors excepted.
In Switch-off warning you can set a "flashing" which starts shortly before the switch
off. Define the warning time and the on/off rhythm.
6.3.5. Block function
The "Block function" menu item only appears if "Use blocking object" is selected in the
settings for the switch function channel: yes’ is selected.
The output channel can be blocked by a blocking telegram. Here it is defined what hap-
pens during the block, when bus voltage is restored and after the block. Manual oper-
ation is not possible when the block is active.
The function can be used, for example, for a light that switches on when a "panic but-
ton" (= trigger for blocking function) is pressed and can no longer be switched off.
6.3.6. Scenes
A group address for scenes must be filed in the KNX system to control the scenes.
The input object ‘Channel - call/save scenes’ of the actuator is linked to this group ad-
dress.
A scene is called, then the scene number is communicated to the actuator. The state
stored in the actuator for this scene number is switched.
If the scene saving function is used, then the switch state is saved for this scene num-
ber in the actuator.
The "Scenes" menu item of the actuator only appears if "Use scenes" is selected in the
settings for the switch function: yes’ is selected. The actuator has 8 scene memories
for switch states.
Activate a scene save point.
Assign a scene number to the scene save point. The switch state stored in the actuator
is retrieved/stored via this scene number. Make sure that every scene number is used
only once per drive channel.

16 Setting parameters
Actuator KNX R1-B4 compact 16 A • Version: 28.05.2020 • Technical changes and errors excepted.
Specify a switch state. If it is allowed to save scenes via the bus, this state only applies
after the ETS download until the first manual saving. Afterwards, the new switch state
saved in the actuator is used.
6.4. Inputs
6.4.1. Input As a bus button
Input 1 can be defined as bus or actuator button. The inputs 2-4 are bus buttons.
If the input is used as a free bus button, it sends a previously set value to the bus when
activated. Various parameters for frequently used bus functions are integrated in the
program file of the actuator. The inputs can be configured very easily as switches, drive
controls, dimmers, for sending values and for scene recall.
Input as switch:
If a button with switching function is assigned to the input, select the bus function
"Switch" and define which value is sent when the button is pressed/released and when
it is sent.

the button function, time interval (switching/dimming) and if required, the repeat inter-
val for extended pressing of the button.
The input can be disabled with a blocking object. For active blocking there is \no bus
communication.
Input as 8 bit encoder:
If the input is to be used as an 8-bit encoder, select the bus function "8-bit encoder" and
define which value is to be transmitted.
The input can be disabled with a blocking object. For active blocking there is no bus
communication.
Input as temperature encoder:
If the input is to be used as a temperature encoder, select the bus function "Tempera-
ture encoder" and define which value is to be transmitted between -30°C and +80°C.
By sending a temperature value, for example, the set point of the temperature control
can be changed.
