2 Application
The precipitation sensor serves as measuring instrument for the determination of the
instantaneous precipitation intensities (mm precipitation / min.). By integration of the
precipitation intensities, the precipitation quantity can be calculated, as well. Control- and
warning signals can be derived from the precipitation intensity.
The measuring signal is output as intensity-dependent analogue output value. The dimension
of the measurement value output is divided into 4 linear characteristic segments, which show a
tenth of the slope of the more sensitive segment.
Thus, it is possible to represent an intensity range from approx. 0,001mm/min. (light drizzle) up
to 10mm/min. (extremely heavy rain) with reasonable resolution (quasi-logarithmic output).
3 Construction and Mode of Operation
Precipitation in the form of drizzle, rain, snow, or hail falls through a light band, induced by light
diodes, and lead to shadowing effects on the receiving side. The sent light is pulse-modulated.
From the extent of shading along with the duration of falling through a factor is calculated that
gives the information if there is a precipitation incident or not.
Heating
The instrument is equipped with a heating system for extreme weather condition. This avoids
ice and snow forming on the housing surface. In addition, the surface retains a temperature of
>0° by means of a regulated heating. The heating is always active, the control temperature is
approx. 8°C.
At the end of the precipitation the analogue output goes in one time of 180sec. (5.4103.2x.041,
5.4103.20.741) or 50sec. (5.4103.20.641) to 4mA. If the precipitation starts, the analog output
rises again to the measured value.
Housing
The housing consists of polycarbonate, the support of stainless steel.
A special coating serves for reducing measurement errors which might arise by drop formation
at the housing in the range of the measured distance. This coating must not be removed.

4 Installation
Please Note:
The hydrophilic coating must not be damaged. The electrical connection is to be
carried out by experts only. Please open the instrument only with dry ambient
conditions. Do not damage the exposed electronics!
Remark:
In order to achieve an optimal electro-magnetic immunity (> 20V/m) please use shielded
cable.
4.1 Mechanical Mounting
Note:
When mounting and aligning, take into
account that direct sunlight on the receiving
diodes can cause the sensor to malfunction.
When using several precipitation sensors in
parallel operation, the distance between the
mast must be greater than 1.5m.
When using sensors of other manufacturers
with infrared measuring technology, it must
be excluded that the receiving diodes of the
precipitation sensor are disturbed. This can
be realized e.g. by appropriate alignment of
the sensors.
5.4103.10.xxx
The operating position of the precipitation
monitor is horizontal.
The mounting system of the instrument is
designed for attachment to a mast. When
mounting make sure, that the precipitation
can easily reach the sensor field, and that
the instrument, while operating, is not
exposed to strong vibrations or shocks.
The pictured tube is not included in delivery.

Clamp connection
Note:
The 5.4103.20.641 has a bridge rectifier at the input of the power supply
This means, that the power supply "-" does not have the same potential
as output "-". Power supply "-" and output "-" must not be connected.
All other variants have half-wave rectification at the input of the power
supply. There is the power supply "-" and has the same potential as
output "-".

Remark:
The cable shield must only be connected on the side of the power supply.
5 Taking into Operation
After the electrical connection has been established, and the case has been screwed, the
operating voltage can be switched on. The dimension of the measurement value output is
reset when the supply voltage is switched on.
6 Maintenance
The device is maintenance free.
Cleaning:
The pollution and the pollution level is dependent on the location. Therefore, we recommend
the unit be checked at appropriate intervals and cleaned if necessary.
For the cleaning should use a damp cloth without chemical cleaning agents are used.
Remark:
The housing is coated in the front section and in the sensor area. This coating must not be
damaged.
We recommend to clean (rinse) the instrument only with water, and to blot it with a soft cloth, if
necessary. Please take care that no water gets into the instrument. Excessive rubbing might
remove the coating.
Events can, possibly, be activated with the cleaning work; they should be considered then with
the evaluation / further processing.
Order-No.
