Technical specifications and installation instructions
Item number 70119
1.
Description
The KNX L brightness sensor measures the intensity of illumination and transfers
the value to the KNX system. Six switching outputs with adjustable threshold values
as well as additional AND and OR logic gates are available. The sensor system, the
evaluation electronics and the electronics of the bus connection are mounted in a
compact housing.
Functions:
•
Brightness measurement: The current light intensity is measured by a
sensor
•
3 threshold values for twilight (up to 1000 lux), 3 for daylight (1-99 klux),
can be adjusted per parameter or via communication objects
•
8 AND and 8 OR logic gates with each 4 inputs. Every switching incident
as well as 8 logic inputs (in the form of communication objects) may be used
as inputs for the logic gates. The output of each gate may optionally be
configured as 1 bit or 2 x 8 bits
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.

KNX L brightness sensor
Use the device exclusively for building automation and observe the operating inst-
ructions. Improper use, modifications to the device or failure to observe the opera-
ting instructions 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
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.
2.1. Location
Select an assembly location at the building where sun may be collected by the sen-
sors unobstructedly. The sensor may not be shaded by the building or for example
by trees.
At least 60 cm of clearance must be left all round the device. Concurrently, the pre-
vents spray (raindrops hitting the device) or snow (snow penetration) from impai-
ring the measurement. It also does not allow birds to bite it. Please ensure that the
extended awning does not cast shade on the unit, and that this is not protected from
the wind.

2.2. Mounting the sensor
2.2.1. Attaching the mount
The sensor comes with a combination wall/pole mount. The mount comes adhered
by adhesive strips to the rear side of the housing. Fasten the mount vertically onto
the wall or pole.
