Description
KNX L brightness sensor
• Date of issue: 05.11.2010 • Technical changes reserved. Errors reserved.
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 eva-
luation 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 switching outputs for twilight
(up to 1000 lux), 3 for
daylight
(1-99 klux),
each with adjustable threshold values (Threshold values can be set by
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
programme file
(format
VD2), the data sheet and the manual can be downloaded from the Elsner Elektronik
homepage on
www.elsner-elektronik.de
in the “Service” menu.
