2. Installation and start-up
2.1. Installation notes
Installation, testing, operational start-up and troubleshooting should
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.

5 Installation and start-up
Actuators KNX R4 16 A and KNX R8 16 A • Version: 28.05.2020 • Technical changes and errors excepted.
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.

Actuators KNX R4 16 A and KNX R8 16 A • Version: 28.05.2020 • Technical changes and errors excepted.
The Actuators KNX R4 16 A and KNX R8 16 A are installed on a mounting rail
(series installation). The connection is made using a KNX connector on the KNX data
bus. In addition, a power supply for the connected drive or consumer is necessary (out-
put free of potential).

8 Installation and start-up
Actuators KNX R4 16 A and KNX R8 16 A • Version: 28.05.2020 • Technical changes and errors excepted.
Follow the guidelines and standards for SELV electric circuits
while installing and cable laying of the KNX connection and
inputs!
The physical address is assigned by the KNX software. There is a button with a control
LED for this on the actuator.
2.3.1. Insulation properties of the clamp groups
The Actuators KNX R4 16 A and KNX R8 16 A are assigned to Overvoltage cate-
gory III and Pollution degree 2 or 3 according to EN60664-1. According to this classifi-
cation,
between 250 V power cables and FELV 4 kV surge voltage resistance and
between 250 V power cables and SELV 6 kV surge voltage resistance
must be provided. This provision must be observed during the installation.
With single insulation,
at pollution degree 2 a voltage of 400 V AC and
at pollution degree 3 a voltage of 250 V AC
is allowed between two channels.
KNX R4 16 A:
Neighbouring clamp groups may not be used with mixed
voltages, as there is only single insulation between them.
Non-labelled clamps (X) may not be used, to avoid influencing the insulation proper-
ties!

Insulation 4 kV (single insulation)

9 Installation and start-up
Actuators KNX R4 16 A and KNX R8 16 A • Version: 28.05.2020 • Technical changes and errors excepted.
KNX R8 16 A:
The clamp groups [A1, A2, B1, B2] and [C1, C2, D1, D2] can be used with mixed voltag-
es, as there is increased insulation between them. Non-labelled clamps (X) may not be
used, to avoid influencing the insulation properties!

2.4. Instructions for assembly and operational
start-up.
Never expose actuators to water (e.g. rain) or dust. This can damage the electronics.
You must not exceed a relative air humidity of 95%. Avoid condensation.
After the auxiliary voltage has been applied, the device will enter an initialisation phase
lasting a few seconds. During this phase no information can be received or sent via the
bus.
3. Addressing of the device at the bus
The device is supplied with the bus address 15.15.255. You can program another ad-
dress into the ETS by overwriting the 15.15.255 address or by teaching via the pro-
gramming button.

17 Setting parameters
Actuators KNX R4 16 A and KNX R8 16 A • Version: 28.05.2020 • Technical changes and errors excepted.
6.1. Behaviour on power failure/ restoration of
power
Behaviour following a failure of the bus power supply:
The device sends nothing.
Behaviour on bus restoration of power and following programming or reset:
The device sends all outputs according to their send behaviour set in the parameters
with the delays established in the "General settings" parameter block.
6.2. General settings
First set the general parameters for the bus communication (message rate, transmis-
sion delays). In addition, you can specify whether all or only the changed settings are
transferred to the bus when programming scenes.
The label for objects is placed in front of all the objects of Actuators KNX R4 16
A and KNX R8 16 A, making their assignment more recognisable in the ETS.
Activate the switch function
The actuator KNX R4 16 A has 2 channels A and B with double switch function each.
The actuator KNX R8 16 A has 4 channels A, B, C and D with double switch function
each.
6.3. Switch function
The label for channel objects is placed in front of all the objects of this channel, mak-
ing their assignment more recognisable in the ETS.
The Scenes menu is activated here.
Select the appropriate relay operation for the connected device.
Maximum message rate 1… 20; 5 messages per second
Transmission delay of switching and status
outputs after power restoration
5s… 2 h
When using scenes:
Transfer when programming All parameters • only changed parameters
Object labelling [Free text max. 20 characters]
Channel A Do not use • Double switch function
Label for channel objects [Free text max. 20 characters]

Relay operation Closer • Opener

18 Setting parameters
Actuators KNX R4 16 A and KNX R8 16 A • Version: 28.05.2020 • Technical changes and errors excepted.
Set the behaviour for bus voltage drop and after reset/download.
If necessary, activate the status object that outputs the relay status.
If necessary, activate the link menu that enables a link with AND or OR.
Activate the required time function. Here either the switch-on and/or switch-off can
be delayed or a staircase timer switch can be set up.
If required, activate the Block function menu in which you can define a block.
6.3.1. Relationship between logic operation – timer switch –
Block
