change of address is only required if two neighbouring Wind Sensors or Rain Volume
Sensors are placed within the reception range of the Base Station. The base address of
the Wind Sensor and the Rain Volume Sensor can only exclusively be changed by the
manufacturer, thus requiring the units to be shipped back to the manufacturer, if
necessary.
Note on Storage of Solar Powered Outdoor Sensors
These sensors receive their operating power from a solar cell which also powers an
internal battery to be used during periods of darkness and bad weather.
If any such sensor is taken out of operation for a longer time period without any light there
still is no danger for the internal battery as long as the small magnet required for
activation of operating power has been removed.
This way a sensor in its packaging can be stored for several years.
13. Battery Change
Remote Indoor Sensor, Remote Sensors WS 7015-22, WS 7015-27 and WS 7015-28
The batteries in these sensors have a life expectancy of up to 3 years (Alkaline Batteries).
They have to be changed, if the display of the respective sensor in the base station fails
to appear for a time period exceeding 24 hours and any general and longer lasting
interference of the transmission path is out of the question. The latter can generally be
recognized if the data transmission of other sensors being close to the one missing also
do not work properly (see Item Interferences).
Batteries can be changed by opening the battery compartment of the sensor, removing of
the used-up batteries and replacing them with new Type Mignon AA, IEC LR6, 1.5V
batteries under observance of the correct polarity as marked in the battery compartment.
After replacing of the battery cover the sensor is ready to operate again. Latest after the
Base Unit has performed its standard search routine (see Item Interferences), the data of
the sensor must again appear on the display.
Base Station
The Base Unit indicates low running batteries by a battery icon in the top portion of the
LCD.
Since stored data may be lost during battery change it is recommended to call off and
note all data, if required, prior to battery change. Then open the two battery covers on the
back of the casing, remove the used-up batteries and replace them with four new Type
Mignon AA, IEC LR6, 1.5V batteries under observance of the correct polarity as marked
in the battery compartment.
The end user is obliged by law (Battery Regulations) to properly dispose
of all used-up batteries and accumulators (button cell to lead-acid
accumulator). Disposal of such items through the garbage is strictly
forbidden.
Used-up batteries can be returned to all municipal recycling centers which
are obliged to accept such items.
Please participate in the preservation of the environment!
Note!
Other parts of the system do not require any battery changes since they are
powered by solar cells. Integrated buffer batteries will cover periods of darkness
and bad weather.
14. Interferences
If any sensor has not been received for a period of 12 hours, its display will cease to show
its values on the LCD. If by temporary disturbances of the transmission path the
synchronization between sensor and base unit is interrupted (transmission only takes
place in a very small time window), the base station will scan all sensor transmitters for 6
minutes at 8.00h a.m. and 6.00h p.m. every day. Latest after that time a temporarily
interrupted reception should be resumed.
Possible interferences preventing correct display of transmitted measurement
values:
Undefined values after setting up.
In order to immediately receive defined data and ensure the correct assignment of all data
telegrams to their display section make sure, that the test mode of the Base Station is
only be terminated after all sensors have ended their test phase.
No reception – distance between transmitter and receiver too long.
Reduce distance between transmitter and receiver. Use Repeater (WS-7015-12) to
extend transmission distance.
No reception – highly shielding materials between transmitter and receiver (thick
walls, steel concrete, isolating aluminum foil, etc.).
Find different location for transmitter and/or receiver. See also Item Transmission
Range.
Low batteries in transmitter or receiver.
Change batteries. Observe low battery indicator.
Transmitter is superposed by interfering sources (e.g. wireless radio, headset,
speaker, etc.).
Remove interfering source. Find different location for transmitter and/or receiver. Has no
reception taken place for the last 12 hours, the respective measuring point is shut down
and no measuring value will show, since the system is assuming a sensor no longer in
existence. In order to save battery power there will be no more reception attempts. Every
day at 8.00h a.m. and 6.00h p.m. the receiver will automatically start a new
synchronization whereby a sensor not received for more than 12 hours will be
incorporated into the system again.
Note!
Every newly added Remote Sensor (e.g. after a battery change) will automatically
be entered into the system and its respective data will be displayed.
Quite frequently interferences are only of a temporary nature (e.g. R/T operation) or can
easily be overcome. If there are wireless headsets, remote babysitters or other devices
working on a 433MHz basis in your house or vicinity, their switch-on time is mostly limited.
