3 Description
Sensor Sewi KNX L • Version: 10.09.2018 • Technical Changes and Errors excepted.
1. Description
The Sensor Sewi KNX L for the KNX bus system captures the brightness in the room.
The measurement value 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
• 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 1bit 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 downloaded from the Elsner Elektronik website on www.elsner-elektronik.de in the “Service” menu.

4 Installation and start-up
Sensor Sewi KNX L • Version: 10.09.2018 • Technical Changes and Errors excepted.
The product conforms with the provisions of EU directives.
2. Installation and start-up
2.1. Installation notes
Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.
CAUTION!
Live voltage!
There are unprotected live components inside the device.
• National legal 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 its intended purpose. 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 assembled and after conclusion of all installation and operational start-up tasks and only in
the surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.
2.2. Installation location
Install and use only in dry interior rooms! Avoid condensation.
Brightness sensor:
Measurement range 0 lux … 2,000 lux (higher values can be measured an dis-
played)
Resolution 1 lux at 0…2,000 lux
Accuracy ±15% of the measurement value at 30 lux … 2,000 lux
5 Installation and start-up
Sensor Sewi KNX L • Version: 10.09.2018 • Technical Changes and Errors excepted.
The Sensor Sewi KNX L is installed surface mounted on walls or ceilings.

2.5. Notes on mounting and commissioning
Never expose the device to water (e.g. rain) or dust. This can damage the electronics.
You must not exceed a relative humidity of 95%. Avoid condensation.
The brightness sensor must not be painted over or covered.
After the bus 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.

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 (Fig. 1+2: A).
8 Addressing the equipment
Sensor Sewi KNX L • Version: 10.09.2018 • Technical Changes and Errors excepted.
3. Addressing the equipment
The equipment is delivered with the bus address 15.15.255. You can program a different address in the ETS by overwriting the address 15.15.255 or by teaching the device
via the programming button.
The programming button is on the inside of the housing (Fig. 2: No. 3).
4. Maintenance
The brightness sensor must not get dirty over or covered. As a rule, it is sufficient to
wipe the device with a soft, dry cloth twice a year.
