Sensor module for DIN rail mounting

The LCN-SHS is a sensor module for building installation in Bus technology. It has the
same functions as the LCN-SH, however without electronic (dimming) outputs.

Application

The 2HP sized LCN-SHS module is for installing in
dry rooms in main and normal distribution boxes.

It has 3 electronic outputs (see illustration), which
are seperately controlled. Amongst other things,
the push-button converters LCN-BT4H / LCN­BU4L, the relay contacts LCN-R8H / LCN-R2H /
LCN-R4M2H and also the binary sensors LCN­BT4H/LCN-BU4L (as mentioned above) can be
connected.

The operating programme from the LCN-SHS
includes further functions like 2 proportional
regulators, 5 thresholds, the LCN panel system
etc..

The connection

The module has two connecting blocks: the power supply side with screwless terminals and
the sensor side with three plug connections.

The terminals are colourfully marked as follows

Description: Colour: Function:

orange data wire
blue neutral wire
L,L black phase (live)

The power connections are voltage fixed up to max. 4kV(L+N) according to VDE, additio­nal measures against overvoltage in operational conditions are not necessary. Measures
for lightning protection in the building should be applied as usual (coarse protection).

Note:

As always with electronic, suppressor elements (e.g.VDR´s) are to be planned with coils
from 230V~ contactors and relays, that are installed in the same distribution boxes as the
LCN modules.

Sensor technology

The red sensor connecting plugs are protected only in a low extent against overvoltage. A
contact with 230V will destroy the module. The sensor terminals are on the N potential,
which means they are not decoupled from the electrical isolation. That´s why you must
make sure, that a protection against contact for the user in every operating condition is
ensured. The push-buttons from all of the approved switch panel systems ensure this
protection.

The module has three sensor connections, which can be used as additional switchings, if
necessary as actuator. The functions can be programmed with the setup programme LCN­P or LCN-PRO:

T-connection:

Over a LCN-T8 or push-button converter (LCN-BT4H/BU4L), max. 8 conventional push­buttons can be evaluated. Apart from that, there are a selection of sensors that can be
connected here alternatively. The module has the required analogue value processing with
up to 12bit accuracy.
I-connection:
Here the IR-receiver for the remote control can be connected, additionally the binary
sensor LCN-B3I, the motion detector LCN-BMI, the transponder reader LCN-UT and the
temperature sensor LCN-TS. These components can be operated parallel on the I­connection by using the LCN-IV.
The I-connection can alternatively be served as a counter for pulses up to 1kHz, when no
further periphery is connected.

P-connection:

Here you can connect for example, the 4-way binary sensor (LCN-BT4H/-BU4L), the
current sensor (LCN-BS4) and the relay blocks (LCN-R8H/-R4M2H/-R2H. The LCN­BT4H/BU4L and LCN-BS4 will be detected automatically. The LCN-R8H has to be
activated first with the LCN-P or LCN-PRO .

Notes about the sensor technology:

The module monitors overloads and short circuits (T-, I-, P-port) on its sensor technology.
Should the module be short circuited on its periphery, due to wiring errors, it will switch off
the power supply from the sensor for 4 seconds by itself. If 2 further tests show the same
error, it will switch off for 8s + 30s and a status message will be sent to the bus:

“module reports overload/short circuit periphery.”,

apart from that the red LED will flash cyclic, as long as the sensor technology is
switched off.

In this case check the connected sensor technology and the wiring.
The LCN-SHS module stays accessible and operational even after these errors!

Local Control Network - building controls in perfection

In the menus and help texts found in the programme LCN-PRO, further informations and
properties of the module are available.

Without parameterization the module has no functions.

Because no access to the module is required when first programming, (no programming
button, all functions are controlled over the bus), the module may be installed before being
setting up. In this case the serial number of the unprogrammed module should be noted in
the building plan, for better identification.

Despite its extensive functionalities, the LCN system is simple to install and programme: It´s
all in the hands of the electrician. However a training course is necessary for every
electrician, who installs this system. The direct users support over the telephone hotline,
is only free of charge and open to installers who have taken part in a training course.
