Preparation For Operation, Commissioning; A) Commissioning The Combined Sensor - elv WS 250 Edition Bedienungsanleitung

7. Preparation for operation, commissioning

Please observe:
First of all, put all available outdoor sensors into operation (insert batteries)
and then the base station itself.
If you proceed in the opposite order, it could occur that the base station does
not detect all the existing outdoor sensors.
We always recommend you to first of all try out the base station with all outdoor sensors (in as
much as you have purchased additional outdoor sensors besides the supplied combination
sensor) in a room before installing the outdoor sensors in the open air. However, the distance
between the base station and the out-door sensors should be at least 2 m in order to avoid
interference.
If you notice that one outdoor sensor is out of range after installation, you can assume that radio
reception is not sufficient (and that there is no defect in the outdoor sensor).
This initial function test will save extensive and time-consuming error searches afterwards.
a) Commissioning the combination sensor
• Open the casing of the sensor. First of all, turn the lower casing cover slightly in the direction
of the arrow (1) as shown below and then carefully lower the casing cover.
• Now insert three batteries (LR6/mignon/AA) with the correct polarity
into the battery compartment (see illustration below on the right).
Use preferably alkaline batteries.
Accumulators can also be used but these reduce will
reduce the range due to the lower voltage / capacity as
well as their operating life!
For the first 5 minutes the combination sensor is in a test mode and
sends its data-telegrams in an intervall of approx. 3 seconds. After
completion of the test mode the normal transmission interval of
approx. 155 seconds is activated.
It must be guaranteed that the combination sensor has already
left its test mode when the synchronisation mode of the base
station is terminated, otherwise a normal reception isn't possible.
• Close the sensor casing, slide the cover to the top and lock it again.
• Assemble the installation base.
As already explained above, you should first of all install the sensors
in the garden etc. after a successful initial function test.
It may be difficult to find a favourable place for the combination sensor
as this should stand preferably in the shade in order to measure the
correct temperature. On the other hand, it is also necessary to
consider the functions of the wind and rain sensor.
Closeness to buildings, trees, etc. may impair the measuring values
of the wind and rain sensor.
