Further setting options

Changes of the basic settings are urgently allowed
in power-off mode. Only if necessary, changes of the
basic setting should be carried out by skilled techni-
cian.
Changes of settings will be accepted only after re-
connecting the power supply. Changes of the jump-
ers during operation are not allowed.
Please note, changes of the basic settings by users
will be carried out on own responsibility. The manu-
facturer is not liable for consequential damages.

Overview of the selectable operating modes

4 analog outputs selectable:
0...20 mA · 4...20 mA •  0...5 V · 0...10 V

4 final values of the measuring ranges* for the analog
outputs selectable: 10 / 20 / 25 / 50 [mm]

4 time-frames of the analog outputs for gliding summa-
tion selectable: 1 / 10 / 30 / 60 [minutes]

2 modi for low power operation regarding pulse output
and power supply selectable

Functions of the jumpers

See also tab. 1:

J3 

to select the required mode (Pos. 1-8)

J4, J5 

to switch on the respective analog output

J6 

to switch over the analog voltage output

J12 

to connect the switch output to the power supply for

2 wire circuit of the low power modi (not plugged  = pow-
er supply and pulse output are separated)

User-specific configuration
of the precipitation sensor

Note: These services is required, if the basic settings of the
should be modified by factory.
In principle the changes of the configuration can be carried
out on-site by user themselves.
