3 Description
Sensor Sewi KNX L-Pr • Version: 26.10.2021 • Technical Changes and Errors excepted.
1. Description
The Sensor Sewi KNX L-Pr for the KNX building bus system captures brightness and
the presence of persons in rooms. The brightness value measured can be used for the
control of limit-dependent switching outputs. States can be linked via AND logic gates
and OR logic gates. Multi-function modules change input data as required by means of
calculations, querying a condition, or converting the data point type.
Functions:
•Brightness measurement with brightness control
• Presence of persons is detected
•Threshold values can be adjusted per parameter or via communication
objects
•8 AND and 8 OR logic gates, each with 4 inputs. All switching events as well
as 16 logic inputs in the form of communications objects can be used as inputs
for the logic gates. The output of each gate can be configured optionally as 1-
bit or 2 x 8-bit
•8 multi-function modules (computers) for changing the input data by
calculations, by querying a condition or by converting the data point type
Configuration is made using the KNX software ETS. The product file can be down-
loaded from the Elsner Elektronik website on www.elsner-elektronik.de in the “Ser-
vice” menu.

5 Installation
Sensor Sewi KNX L-Pr • Version: 26.10.2021 • Technical Changes and Errors excepted.
Use the device exclusively for building automation and observe the operating instruc-
tions. Improper use, modifications to the device or failure to observe the operating in-
structions will invalidate any warranty or guarantee claims.
Operate the device only as a fixed-site installation, i.e. only in assembled condition and
after conclusion of all installation and operational start-up tasks, and only in the sur-
roundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.
3. Installation
3.1. Installation location and preparation
Install and use only in dry interior rooms! Avoid condensation.
The Sensor Sewi KNX L-Pr is installed surface mounted on ceilings.
To detect the presence of persons make sure that the desired area is covered by
the sensor's coverage angle and that no obstacles obstruct the recording.

3.2. Connection
For installation and wiring at the KNX connection, the
provisions and standards applicable to SELV circuits must be
complied with!
The Sensor Sewi KNX L-Pr is surface-mounted but at the same time can also be
screwed to a flush-mounted socket.
If the Sensor Sewi KNX L-Pr is installed on a flush-mounted socket, it must not con-
tain any wiring with 230 V.

8 Commissioning
Sensor Sewi KNX L-Pr • Version: 26.10.2021 • Technical Changes and Errors excepted.
4. Commissioning
Brightness sensor, presence sensor and ventilation slots on the side must not be dirty,
painted over or covered.
After the bus voltage has been applied, the unit will enter an initialisation phase lasting
5 seconds. During this period, no information can be received or transmitted via the
bus.
The presence sensor has a start-up phase of approx. 15 seconds, during which the
presence of persons is not detected.
4.1. Addressing the equipment
The individual address is assigned via the ETS. For this purpose there is a button with
a control LED on the unit (Fig. 2, No. 4+5).
The equipment is delivered with the bus address 15.15.255. Another address can be
programmed using the ETS.
5. Maintenance
As a rule, it is sufficient to wipe the device with a soft, dry cloth twice a year.
6. Disposal
After use, the device must be disposed of in accordance with the legal regulations. Do
not dispose of it with the household waste!
Fig. 7
Connect the KNX bus to the KNX terminal.
Fig. 8
Close the housing by positioning the cover
and snapping it into place. To do this, align
the recess on the cover to the marking on the
skirting (the presence sensor must protrude
through the opening in the cover).
