1 General
The Theben Line Coupler S KNX is a modular installation device with a module width of 2 space units. It is
used as a line or area coupler or as a repeater. As a line coupler, the Line coupler S connects a line with a
main line, as an area coupler it connects a main line with an area line. It provides electrical isolation in this
way.
1.1 Using the product manual
This manual provides you with detailed technical information relating to the function, installation and
programming of the Line Coupler. The application of the device is explained using examples.
The manual is divided into the following sections:
•Chapter 1 General
•Chapter 2 Device technology
•Chapter 3 Commissioning
•Chapter A Appendix
1.1.1 Structure of the product manual
Application programs with different ranges of functions can be loaded in the line couple S.
For this reason, all the parameters and functions for ETS 4 and also for ETS 3 are explained in chapter 3.
Note
Different application programs are available with the line coupler S for ETS 3 and ETS 4. Some of the
functions for the ETS 4 are not available in the applications for the ETS 3, see Overview, page 16.
In ETS 3, there is a separate application for coupling and for repeating (Couple/1.x or Repeat/1.x), in
ETS 4, there is a common application (Couple Repeat/2.x).
All applications are upwards compatible, i.e.:
•The old applications of line coupler can be loaded in the line coupler S (ETS 3). This is particularly
useful if in an existing project an line coupler has to be replaced by an line coupler S.
•The applications Couple/1.x or Repeat/1.x can be loaded in the line coupler S via the ETS 3 or the
ETS 4.
•The new application Couple Repeat/2.x with extended functional range is only available for the
ETS 4.

1.2 Product and functional overview
The Line Coupler Line Coupler S can be used as a line/area coupler or as a repeater.
1.2.1 Line/area coupler
As a line/area coupler, the Line Coupler S connects the data flow of two lines but isolates them electrically.
The coupler can route physically addressed, group addressed as well as broadcast telegrams.
In order to route a physically addressed telegram, the Line Coupler S compares the target address with its
own physical address. The physical address of the Line Coupler S determines the line affiliation. The
telegrams are routed or not routed depending on the evaluation and parameterization.
If the Line Coupler S has not yet received its intended project-assigned physical address, this can cause
device faults during commissioning.
The Line Coupler S responds in accordance with its parameterization to telegrams with group addresses.
In order to reduce the telegram traffic, the Line Coupler S only routes telegrams in normal operation
(standard settings), whose group addresses have been entered in its filter table. However, it can be useful,
particularly during commissioning and for diagnostic purposes, to set the option route for both parameters
Group telegrams main group 0…13 and Group telegrams main group 14…31, i.e. the filter table is
switched off. If the system is fully in operation, both parameters should be reset again to the standard
values. The Line Coupler S is then subsequently reprogrammed with the application. Here the correct filter
table will be transferred to the Line Coupler S.
Note
The application Couple Repeat/2.x for the ETS 4 filters the main groups 14…31.
With the application Couple/1.x, no filter table is calculated by the ETS 3 for the main groups 14…31.
For this reason, the main groups 14...31 should not be used. If this is necessary, the parameter Main
group 14…31 must be set with the option route.
If the Line Coupler S routes a telegram and does not receive an acknowledgement or there is a
transmission error, the Line Coupler S repeats the telegram up to three times. With the parameters In case
of errors repeat group telegrams, the response for both lines is set separately. This parameter should be
left as it is in the standard setting.
Normally the Line Coupler S only acknowledges telegrams that it routes. The parameter Telegram
confirmation… facilitates seperate acknowledgement settings for both lines. This parameter should be left
as it is in the standard setting.

Topology
As a line coupler, the device connects a line with a main line. As an area coupler, the line coupler S
connects a main line with an area line. Each line requires its own power supply.
Backbone = Area line with up to 15 area couplers, physical address x.0.0
Main Line = Main line with up to 15 line couplers, physical addres x.y.0
Line = Line with up to 64 devices including the line coupler. Up to 256 devices are possible when up to
three line repeaters are used.
The function of the device is assigned by the assignment of the physical address.
Note
If a second output of the Power Supply SV/S is used for connection, a DV/S choke must be connected.
For further information refer to the Power supply product manual

1.2.2 Repeater
As a repeater, the Line coupler S connects the data flow of two line segments but isolates them
electrically.
Behind a line coupler (in one line), up to three repeaters can be connected in parallel in a line. This is how
up to four line segments form an entire line. A line can thus be expanded from 64 possible devices (1 line)
up to 256 devices (4 line segments). Every line segment must be provided with power by its own KNX
power supply.
The repeaters do not have filter tables. For this reason, a telegram is sent in all line segments
independently of whether or not it is processed in the respective line segment. Whether this telegram is
initiated within the line or whether it has been sent from the main line via the repeater is also irrelevant.
If there is a transmission error of a physically addressed telegram, this telegram is not repeated.
If the repeater routes a telegram and does not receive an acknowledgement or there is a transmission
error, the repeater repeats the telegram up to three times. With the parameters In case of errors repeat
group telegrams, the response for both line segments is set separately.

Topology
Up to three repeaters are connected in parallel in a line. Each line segment requires its own power supply.
Main Line = Main line with up to 15 line couplers
Line = Line with up to three repeaters
Line Segment = Line segment, per segment up to 64 devices are possible (in total up to 256 devices are
possible) including the repeater.
Note
The topology is not defined with the repeater. Under the coupler 1.1.0, the addresses 1.1.0 to 1.1.255
can be assigned as required to the segments.

2.4 Assembly and installation
The Line coupler S is a modular installation device for quick installation in the distribution board on 35 mm
mounting rails to EN 60 715.
The Line coupler S mounting position can be selected as required.
The connection to the bus is established using the supplied bus connection terminals.
Accessibility to the Line coupler S for the purpose of operation, testing, visual inspection, maintenance and
repair must be provided compliant to VDE 0100-520.
Commissioning requirements
In order to commission the Line coupler S, a PC with ETS and a KNX interface, e.g. USB or IP, are
required. The Line coupler S is ready for operation, after bus voltage is connected to the main line.
For programming the Line Coupler, it is necessary to at least connect the primary line. If the secondary
subline is also connected, the Line coupler S can also be programmed from the secondary subline.
The installation and commissioning may only be carried out by electrical specialists. The appropriate
norms, guidelines, regulations and specifications for your country should be observed when planning and
setting up electrical installations and security systems for intrusion and fire detection.
Protect the device from damp, dirt and damage during transport, storage and operation.
Only operate the device within the specified technical data limits!
The device should only be operated in an enclosed housing (distribution board)!
Supplied state
The Line coupler S is supplied with the physical address 15.15.0.
Assignment of the physical address
The assignment and programming of the physical address is carried out in the ETS.
Button on the Line coupler S is pressed to assign the physical address. The red LED lights up. It
switches off, as soon as the ETS has assigned the physical address or button has been pressed
again. The selection of the physical address is dependent on the required device function (coupler or
repeater).
For further information see: Product and functional overview, page 5.
Cleaning
If devices become dirty, they can be cleaned using a dry cloth or a cloth dampened with a soapy solution.
Corrosive agents or solutions should never be used.
Maintenance
The Line coupler S is maintenance-free. No repairs should be carried out by unauthorised personnel if
damage occurs, e.g. during transport and/or storage.
