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 out-
puts. States can be linked via AND logic gates and OR logic gates. Multi-function mod-
ules 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 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.

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 assem-
bled 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.

Sensor Sewi KNX L • Version: 10.09.2018 • Technical Changes and Errors excepted.
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 last-
ing 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 differ-
ent 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.

17 Parameter setting
Sensor Sewi KNX L • Version: 10.09.2018 • Technical Changes and Errors excepted.
6.2. General settings
Set basic characteristics for the data transfer.
6.3. Light control
For light control, the Sensor Sewi KNX L detects the brightness in the room.
Activate the light control.
Set, in which cases the data received via object for setpoint value, setpoint value-ac-
tual difference, dimming increment and times are to be retained. Please note that the
setting "After power supply restoration and programming" should not be used for the
initial start-up, as the factory settings are always used until the first communication.
Set the setpoint value for the brightness in the room and specify whether, besi-
des the dimming information defined below, a switching object should also be sent.
With Sensor Sewi KNX L, the regulation is always started or stopped by an object.
Set the object evaluation and the object value prior to the first communication.
At the end of the regulation, either "nothing"(status remains unchanged), an on or off
command (via the activated switching object) or a dim value can be sent.
Send delay after power-up and programming for:
Measured values 5 s • ... • 2 h
Threshold values and switching outputs 5 s • ... • 2 h
Computer objects 5 s • ... • 2 h
Logic objects 5 s • ... • 2 h
Maximum telegram rate • 1 message per second
• ...
• 5 messages per second
• ...
• 20 messages per second
Use control No • Yes
Maintain the
data received via object setpoint value,
setpoint value-actual difference, dimming
increment and times
• never
• after power supply restoration
• after power supply restoration and
programming
Setpoint value in Lux 0...60000; 500
Send switching object No • Yes
Regulation starts on Reception of a start/stop-object
Regulation stops on Reception of a start/stop-object

18 Parameter setting
Sensor Sewi KNX L • Version: 10.09.2018 • Technical Changes and Errors excepted.
Set, at which deviation from the setpoint value a dim command is to be sent. Spe-
cify the dimming increment and the repetition cycle for the dim command.
Define, up to which response value the dim actuator sends a brighter or darker com-
mand. On the one hand, this defines the range of use for the lamp, on the other hand,
once the minimum or maximum value has been reached, no unnecessary messages
are sent to the bus.
The light regulation can be interrupted during switching or dimming by response
objects, i.e. nothing else is transmitted via the dim output. This results in manual light
operation having priority.
Set, which objects will trigger interruption and when the regulation is to be continued.
Object evaluation • 1 = start | 0 = stop
• 0 = start | 1 = stop
Object value prior to first communication 0 • 1
Reaction to stop • send nothing
• send off command
• send on command
• send value
Value in % 0...100
Send the dim command, if • the actual value deviates from the set-
point value by more than X%
• the actual value deviates from the set-
point value by more than X Lux
Target / actual difference in %
(for a deviation in %)
1...100; 20
Target / actual difference in Lux
(for a deviation in Lux)
1...2500; 100
Dimmer increments 100.00% • 50.00% • 25.00% • 12.5% • 6.25% •
3.13% • 1.56%
Repetition of the dim command in seconds 1...600; 6
Dim brighter with response value in % 1...100
Dim darker with response value in % 0...99
Use interruptions No • Yes
Interrupt regulation when
Reception from response switching object No • Yes
Reception from response dimming object No • Yes
Continue regulation • after a waiting period
• at object reception after waiting period
• at object reception or after waiting period
Waiting period in seconds 5...72000 (Standard value depending on the
setting of "continue regulation")
Object value 0 • 1 • 0 or 1
