ATTENTION! Installation and connection of the device to the mains must only be carried

out by qualiﬁed personnel! Be sure to turn oﬀ the power before installing or removing the

device! Even when the device is turned oﬀ, the output terminals can be live! Do not

connect to the outputs a load that exceeds the recommended values! The design of the

device meets the requirements of electrical safety according to GOST 12.2.007.0-75.

2 OPERATIONAL DESCRIPTION

In network installations LC-S.1 can be used as KNX TP area/line coupler or KNX TP line repeater. Aer

connecting the main line, LC-S.1 operates with its default settings. Setting the correct Individual Address

is necessary. Only Individual Addresses x.y.0 are allowed.

Figure 1. TP coupler application program

When LC-S.1 receives telegrams (for example during commissioning) that use Individual Addresses as

destination addresses, it compares the Individual Addresses of the receiver with its own Individual

Address and decides on that whether it has to route the telegrams or not.

When LC-S.1 receives telegrams that use group addresses as destination addresses, it reacts in

accordance with the parameter settings. During normal operation (with Group Telegram routing set to

ﬁlter), LC-S.1 only routes telegrams whose group addresses are entered in its ﬁlter table.

If a telegram is routed by LC-S.1 without receiving the corresponding acknowledgement, i.e. due to a

missing receiver or to a transmission error, the telegram will be repeated up to three times (depending on

the ETS setting). With the parameters «Repetitions if errors...», this function can be conﬁgured separately

for each line and both kinds of telegrams. It is recommended to use the default parameter setting.

If not already conﬁgured as «Line Coupler», the ETS application program «TP Coupler» has to be

downloaded to the device. Under the Information tab the conﬁguration setting can be changed by the

drop-down menu «Change Application Program». Aer changing the conﬁguration setting the ﬁlter table

entries can be added manually. Updating the application program version can also be done here.

2.2 TP REPEATER APPLICATION

Any received telegram is routed to all lines irrespective of in which line it is processed. Line repeaters

make no use of a ﬁlter table. It is therefore not important whether the telegram is generated within a line

or whether it is sent from an upper line to a lower line via a coupler.

If a telegram is routed by LC-S.1 without receiving the corresponding acknowledgement, i.e. due to a

missing receiver or to a transmission error, the telegram will be repeated up to three times (depending on

the ETS setting). With the parameters «Repetitions if errors...», this function can be conﬁgured separately

for each line and both kinds of telegrams. It is recommended to use the default parameter setting.

If not already conﬁgured as Line/Area/BB Repeater, the ETS application program

«TP repeater» has to be downloaded to the device. Under the Information tab the conﬁguration setting

can be changed by the drop-down menu «Change Application Program». Aer changing the conﬁguration

setting the ﬁlter table entries can be added manually. Updating the application program version can also

be done here.

2.3 KNX NETWORK INSTALLATION

For line coupler functionality in a KNX network LC-S.1 has to use the correct Individual Address of a line

coupler (x.y.0, 1≤ x & y ≤15). In ETS up to 225 addresses can be deﬁned (from 1.1.0 to 15.15.0).

For area coupler functionality in a KNX network LC-S.1 has to use the correct Individual Address of an area

coupler (x.0.0, 1≤ x ≤15). In ETS up to 15 areas can be deﬁned.

If LC-S.1 is used in a KNX system for both purposes, it is only necessary to ensure that the LC-S.1 used as a

line coupler has a line coupler address assigned from a free addressing area. Following ﬁgure illustrates

the LC-S.1 router topology for KNX lines and KNX areas.

2.3.1 INDIVIDUAL ADDRESS

Figure 3. LC-S.1 network

Example: If an area coupler with address 1.0.0 already exists on the backbone no line coupler with

address 1.x.0, 1≤ x ≤15 can be added here. Even if no line coupler with address 1.1.0 exists on

the subline of the 1.0.0 area coupler. Vice versa, if a line coupler with address 1.1.0 already

exists in the installation no area coupler with address 1.0.0 can be added.

2.3.2 KNX TOPOLOGY

Via a line/area coupler up to 15 lines can be connected to a main line called an area. It is possible to have

up to 64 bus devices on one line. With use of line repeaters a line can theoretically be extended to 255 bus

devices. This means up to four line segments form a single KNX TP line. But it is common practice on

exceeding 64 bus devices to insert a new line instead of extending the originating one.

The free tree structure of the KNX topology prevents problems caused by circling telegrams and heavy

bus load. To maintain this condition, interconnection between lines or line segments is strictly forbidden.

Figure 4. LC-S.1 network topology

Each line segment requires its own KNX power supply unit.

Using repeaters on the backbone and main lines is not allowed.

Interconnections are not allowed.
