generally displayed in the display section in the upper left part of the LCD. After insertion
of the batteries the sensor is immediately operable.
Remote Outdoor Sensor
The mounting of the sensor should take place anywhere to the west or north since
temperatures in meteorology usually are measured in the shadow. It can however be
mounted at any other location if desired. It simply must be observed that the solar cell
powering the sensor does have to point towards the light in any case. The sensor must
not be obstructed by any close impediments such as leaves or the like since this will
prevent the solar cell from efficiently powering the sensor. A thinkable mounting location
would e.g. be a spot beneath the roof extension.
The sensor is designed for wall or mast mounting, which can be performed in the
following way:
Either mount the wall holder of the sensor in an exact perpendicular position to a wall by
means of four screws or to a mast by use of the supplied mounting bracket.
Place the sensor into the wall holder and secure both parts by use of the supplied screw.
Ensure that the large protective hood lies on top and the solar cell is pointing towards the
light.
During darkness and periods of bad weather with a relative lack of sunlight an internal
battery system buffered by the solar cell will take care of the sensor’s power supply.
Remote Rain Volume Sensor
Generally mount the Remote Rain Volume Sensor with its solar cell pointing in a southerly
direction.
The Rain Volume Sensor must be securely mounted to an exact horizontal surface by
means of its mounting holes in the bottom part of the housing. Prior to this remove the
upper part from the lower portion by pressing and turning the upper part clockwise with
regard to the bottom part. Remove the transport protection from the seesaw in the lower
part of the sensor and check by tilting that the seesaw can move freely and easily to its
both endpositions.
A cavity in form of a „T“ in the bottom part of the Rain Volume Sensor can be filled with
water and thus allows an exact horizontal alignment without any other auxiliary means.
Fill a small amount of water into this cavity and align the bottom part of the sensor by
principle of a spirit-level. After marking the exact mounting position the water can be
removed. Observe the southerly alignment for the solar cell. By doing this the short
leg of the engraved spirit-level must point to the north.
In order to reach the best possible remote
transmission (high transmission range) it is
recommended not to mount the Rain Volume
Sensor too close to the ground. Mounting the
unit at a height of appr. 3.3 ft (1 m) also reduces
the danger of pollution (especially the solar cell).
Observing the correct polarity insert the color
marked magnet into the holder.
Important Note!
In order to avoid start-up problems make
sure that the color marked magnet is inserted
observing the correct polarity as shown in
the illustration opposite.
After securely screwing the bottom part of the sensor to the mounting surface replace the
upper part as follows:
On the side of the counting seesaw for the rain volume in the bottom part of the sensor
there is a bar magnet mounted in the center initialising the counting pulses for the
electronics.
The top of the housing has now to be replaced in such a way that the solar cell is also
placed on the side of the magnet with the electronics part also directly opposite and the
three retaining hooks exactly fitting into the holders in the bottom part. Turn the upper part
carefully in a counter-clockwise direction until the retaining hooks tightly lock into place.
The Remote Rain Volume Sensor is now operable. For testing purposes very slowly pour
a small amount of water into the funnel. The collected amount will later be computed and
displayed in inch or mm in the Base Station.
Note!
When mounting the Remote Rain Volume Sensor make sure that the collected
water can drain off easily without any obstruction (even in case of sleet or snow).
8. Setting Up
Before setting up, the Intended Use as well as the various Safety
Notes and the Specifications have to be closely observed. Make
sure before setting up that the device does fit the intended
purpose for which you want to use it.
Activating the Sensors
The Outdoor Sensors for wind measurement, acquisition of rain volume and
measurement of outdoor temperature and humidity are for power supply equipped with a
solar cell as well as a Lithium buffer battery for periods of darkness and bad weather.
In oder to protect the precious batteries from over-discharging during long storage periods
without incidence of light to the solar cell (e.g. when packaged), the power supply is only
activated by means of a small magnet which must be inserted into the sensor from the
outside prior to first setup. The magnet belonging to the respective sensor should thus
only be inserted a short time before the Base Station is put into operation.
