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.
2.3. 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-2500-25 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).
To obtain the best possible wireless emissions (high range) it is advisable not to
place the rain sensor directly on the ground. By mounting the sensor about 3 feet (1
m) above the ground the danger of soiling (especially the solar cells) is reduced.
After screwing on the lower part to the base secure the upper part as follows:
There is a bar magnet centrally located on the side on the counting rocker for the
water level in the base. The bar magnet initiates the counting pulses to the
