10.2.2 Explanation of LED-status for displaying of functional status
The actual functional status of the measurement device will be shown by flashing LEDs.
LED-Display Evaluation Comment
green LED is flashing
Measurement
Measurement for reclassification of
residual hardness is activated
green and yellow LED are flashing
Calibration mode
Measurement system is calibrating
resp. verifying the exceeding of the
threshold value
yellow LED is flashing
OFF-Line-Mode
Measurement system was set exter-
nal into OFF-Line-Mode
No hardness evaluation and moni-
toring will be done
yellow and red LED are flashing
soiled valves / leaking
Service alarm!!!
Inadmissible mixture of the water is
recognized, most likely originated
by soiled valves.

check valves for tightness,

clean or change valves
green and red LED is flashing
sensor not recognized
Service alarm!!!
The measuring system has no elec-
trical contact to the hardness sen-
sor.

check the plug-in connection
from hardness sensor to device
red LED is flashing
brine in soft water detected
immediate threshold value
alarm!!!
Brine in soft water recognized.

check softening plant
Attention: too high and long taking
influences of brine will damage the
hardness sensor!
all LEDs are flashing
low sensor quality
Service alarm!!!
low sensor quality

chance sensor
Alternatively malfunction of sof-
tening plant during calibration. In
this case check quality of soft water
and re-start measuring device by
interruption of power supply.
In case of recurrence change sen-
sor.
Note: In case of service alarm no hardness measurement is possible.
Are there recognized several alarms at one time, they will be shown according priorities and
order of their elimination.
