B.1.2 The USH-9 reboots repeatedly
Reason
Solution
The power supply has not enough current to
start the USH-9.
Verify that the power supply provides enough
current. A USH-9 consumes up to 140 mA @ 12
V. If required, power the USH-9 by an additional
or alternative supply.
B.2
Measurement data
B.2.1
Measurement data are not updated
The device is connected to the Commander, but the data are not updated.
Cause
Solution
Data traffic conflict
Reboot the device by interrupting the power supply.
B.2.2 Snow height increase is retarded
Reason
Solution
Drifting snow has resulted in a fast change of
the snow height.
Increase
RoC, max. without precip. (./h)
to
approx. 40 mm/h.
The USH-9 does not recognize precipitation
properly:
● The distance between the sensor and the
snow surface is < 2 m.
● Snow drift close to the surface is not recog-
nized as precipitation.
Increase
RoC, max. without precip. (./h)
NOTE
In snow applications a rate of change (RoC) filter is active! To test the USH-9
use the function
or set
to
Water
.
