Characteristics
Possible cause
Fill level value deviates significantly
Surface of fill level sensor is soiled.
from actual level.
Fill level remains at a certain percentage.
Device is no longer capable of transmitting
No new fill levels detected
data.
Batteries are discharged.
Device no longer carries out measurements. Housing is not closed properly. Check whet-
Surface of fill level sensor is soiled
Data not visible.
Note that data transfer may differ
depending on the device configuration.
WiFi not available.
Incorrect configuration of WiFi and device
Fill level value is 255
Dispenser unable to reliably determine
fill level. Dispenser requires at least
30 activations after device was last
closed to determine fill level.
Highly viscous filling medium forms layer of
film on dispenser bottle wall.
Dispenser is empty.
Device cannot communicate with
Message collector not running.
message collector
Server configuration of device is faulty.
Message collector has no internet con-
nection.
Proxy settings of message collector not
adapted.
A previous attempt at transmission failed.
Device assumes a faulty configuration or
network problem.

Solution
Carefully clean and dry surface of fill level
sensor. There should be no soap, cleaning
agent or liquid residue on sensor surface.
Check whether fill level LED still functions.
If yes, sensor is working but data are not
being transmitted. Check WiFi connection
of device.
Change the batteries.
her LEDs flash when housing is closed.
Carefully clean and dry surface of fill level
sensor. There should be no soap, cleaning
agent or liquid residue on sensor surface.
Check configuration of device.
Check WiFi connection.
Check configuration and if necessary
rectify.
Wait and do not open dispenser.
Use a filling medium with better viscosity.
Refill dispenser.
Start message collector
Configure device.
Connect to internet.
Adapt proxy settings.
Device starts waiting phase (standard:
8 hours). A new transmission attempt is
not normally possible until after this phase.
To start an earlier transmission, open and
close the housing of the device.
