3 Description
Rain Sensor KNX R • Status: 20.08.2013 • Technical changes reserved. Errors reserved.
1. Description
The Rain Sensor KNX R registers precipitation and transfers the status to the KNX
system. One switching output as well as 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:
•Precipitation perception: The surface of the sensor is heated so that only
drops and flakes are recognised as precipitation but not fog or dew. If it stops
raining or snowing, the sensor dries quickly and the precipitation message
ends
•1 switching output
•4 AND and 4 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 VD),
the data sheet and the manual can be downloaded from the Elsner Elektronik
homepage on www.elsner-elektronik.de in the “Service” menu.

• EN 50491-5-2: 2011
2. Installation and commissioning
2.1. Installation notes
Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.
DANGER!
Risk to life from live voltage (mains voltage)!
There are unprotected live components within 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. Location
Select an assembly location at the building where precipitation may be collected by the
sensor unobstructedly. Do not assemble any construction components above the sen-

sor from where water may drop on to the rain sensor after it has stopped raining or
snowing.
2.3. Mounting the sensor
2.3.1. 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.
Fig. 1
The rain sensor must be mounted onto a ver-
tical wall (or pole).

Different mounting arms are available from El-
sner Elektronik as additional, optional accesso-
ries for flexible installation of the weather station
on a wall, pole or beam.
Example of the use of a mounting arm: Due to
flexible ball joints, the sensor can be brought
into ideal position.

2.3.3. Preparing the sensor
The sensor cover snaps in on the left and right along the bottom edge (see Fig.). The
cover of the 230V model is also screwed on top. Remove the cover. Proceed carefully,
so as not to pull off the wire connecting the PCB in the bottom part with the rain sensor
in the cover (soldered cable connection in case of 230 V AC version, cable with plug in
case of 24 V DC version).
Push the bus connection cable through the rubber seal on the bottom of the sensor and
connect bus +/- to the provided clamps.
For 24V devices the connection cable must be plugged in between the cover and circuit
board.
