Sewi KNX L
Indoor brightness sensor
Technical specifications and installation instructions
Item numbers 70395 (white), 70695 (jet black)
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 swit-
ching 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 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 dow-
nloaded from the Elsner Elektronik website on www.elsner-elektronik.de in the
"Service" menu.

2. Safety and use instructions

2.1. General 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.
• When planning and installing electrical systems, observe the
applicable directives, regulations and provisions of the
respective country.
• Ensure that the device or system can be disconnected. During
installation, disconnect all cables from the power supply and
take safety precautions against unintentional switch-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 the intended purpose described in this manual. 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 as-
sembled 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.
3. Installation

3.1. Installation location and preparation

Install and use only in dry interior rooms! Avoid condensation.
The Sensor Sewi KNX L is installed surface mounted on walls or ceilings.

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 is surface-mounted but at the same time can also be scre-
wed to a flush-mounted socket.
If the Sensor Sewi KNX L is installed on a flush-mounted socket, it must not con-
tain any wiring with 230 V.
