Please note!
Previous weather sensors with software Version 1.1.
Depending on the type and the period of manufacture, the WS-2510 system sensors are supplied
in two software versions (see printing/sticker on the sensor or the packaging). The weather
station is always set to Version 1.2 after commissioning. If you are using Version 1.1 sensors
(supplied before 5/2000), signals from these will not initially be received. However, as the
weather station can add new sensors to its sensor management at any time, it is possible to add
any sensors with software version 1.1.even retrospectively.
-
When the weather station has automatically completed the initialization mode or the user
has terminated it manually, the configuration mode can be called up by pressing the
“ALARM VALUES ” key (bottom right of the control panel) for approximately 3 seconds.
-
In this mode, next press the “SENSOR ADMIN ” key. The currently set version number for
the outdoor sensors will be displayed at the top left (factory setting 1.2).
-
The version can be switched to 1.1 by touching this display field. In doing so however,
signals from Version 1.2 sensors will continue to be received, the weather station being
merely set up to receive signals from Version 1.1 in addition.
-
When this is done, the improved transmission reliability of Version 1.2 will be lost.
-
You can subsequently exit the configuration mode by pressing the “END ” key.
-
The weather station now switches to normal operation, starts trying to receive signals from
all sensors for 6 minutes in the background and inserts these automatically into the sensor
administration.
2.2.
The outdoor sensors
The outdoor sensors for wind and brightness measurement, for recording rainfall and for external
temperature/humidity measurement are equipped with a solar cell and a lithium backup battery to
provide power during the hours of darkness and periods of bad weather.
To prevent the batteries from discharging fully during a long period of storage without light falling
on the solar cell (e.g. when in the packaging), the power supply is activated by a small magnet
that has to be inserted from the outside before the initial start-up. Do not insert the sensor magnet
until shortly before field site assembly of each sensor. Before being used for the first time and
when the battery is discharged, sensors should be exposed to strong light for one or more days
without the activation magnet being inserted so that the backup battery is charged via the solar
cell.
After activation (insertion of the magnets, or batteries for battery supplied sensors), the sensors
transmit for 10 minutes in test mode. This means instead of the normal 3-minute scan, they
transmit during this period in a 4-second scan. This ensures optimum reception in the initialization
phase. If the signal from the sensor is unable to be received within this time, then the reception is
affected and should be improved by re-positioning the sensor.
The external temperature and humidity sensors should be addressed according to section 2.3.4.
2.2.1.
Insertion of magnets into the outdoor sensors
In the WS 2510-25 and WS 2510-19 outdoor sensors, the magnet for activating the system is
pressed into an opening provided for it in the rear of the housing.
The wind sensor (WS 2510-15) is also activated by inserting a small magnet into the opening
provided. The magnet holder is located above the holding pipe fixing (opposite the solar cell).
To insert the magnet in the WS 2510-16 rain sensor press the upper section against the lower
section and turn clockwise. On the housing cover of the electronic housing incorporated into the
funnel there is a slot for the small round magnet. The rain sensor starts transmitting after pressing
the magnet into the slot.

Description, Installation and Commissioning of sensors
The WS-2510 sensor design consists of two groups of sensors. The WS 2510-19 brightness
sensor, the WS 2510-16 rainfall sensor and the WS 2510-15 wind sensor are permanently set to
address 7 in the factory. If necessary, e.g. when several sensor systems are operated in the
immediate vicinity of one another, their address can be changed in the factory.
The second group of sensors is the WS 2510-22, WS 2510-25 and WS 2510-27 types. A
maximum of eight of this type of sensor can be used and are selected using the sensor selection
on the display. Therefore each has to be assigned an address. For these types, be sure to
observe the instructions for addressing.
2.3.1
WS 2510-15 wind sensor
The wind sensor measures both the wind direction and the wind speed at the mounting location.
It is powered by a solar cell, and a back-up battery during the hours of darkness, and has a non-
user definable address.
It is mounted either on a mast or high up on a wall. It is important at the sensor location that the
solar cell in the sensor housing faces directly south and is unshielded on all sides, i.e. the wind
can reach the sensor unimpeded from all sides.
The exact alignment of the sensor to the south is very important as this alignment acts as
reference for the wind directional measuring device.
In order to obtain precise measurements ensure that the sensor is mounted vertically in the
mounting tube.
Finally screw the mounting tube and the sensor together to ensure a firm base for all the
components.
In its basic form the wind sensor should be aligned in the north-south direction (solar cell to the
south), in order to provide the precise north reference for the evaluation electronics.
2.3.2
WS 2510-16 rain sensor
The rain sensor is also powered by solar energy and has an address that cannot be changed by
the user.
In this case the alignment of the solar cell is directly towards the south.
The rain sensor should be secured to an exactly horizontal surface using the securing holes at
the base of the housing. First remove the upper part by pressing against the lower part and
turning clockwise. In the lower part is a depression that, when filled with water, permits a precise
horizontal alignment without additional assistance.
Pour a small amount of water into this depression and align the lower section of the housing
using the spirit level principle. After marking the exact installation location the water can be
removed. Note the south alignment for the solar cell. The shank of the built-in spirit level must
point to the north (see diagram).
