P. 15
Error code
Meaning
Error
E 1
Invalid input value.
Error
E 2
Signal value of the LITRO-sensor is too small (signal current less than 3.7 mA).
In case of the secu4 the sensorbox transmits invalid data (probe error).
Disconnect the current supply and turn the device back on. If the error lasts for at
least 5 min. the LITRO-sensor or the sensorbox is defective.
Error
E 3
Measuring value of the LITRO-sensor is too high for offset calibration. The probe
must not be plunged! A current of 4
.
5 mA or higher indicates a probe problem.
Error
E 4
Measured value is implausible. Perform menu item
‘9.Offset probe’.
Error
E 5
Height input is larger than tank height. (Wrong input)
Error
E 6
The measured value is too small for reference. Make sure the probe is plunged.
The appointed height is too big or the measuring value (resp. the filling level) is too
small for setting. Perform step
‘9. Offset probe’. Otherwise probe error.
Error
E 7
The measured value is too small for the appointed tank height or tank volume.
Make sure the probe is plunged!
Error
E 8
For
secu4:
The high test pressure during the maintenance check (s. page 20)
was fully reached. This was the aim of the test. So no error is present.
For LITRO-sensor: Wait until the loading phase after the initial start is
completed (max. 5min.). Otherwise the sensor is not connected properly.
Plus (= blue or white or red) => connect to clamp 1.
The second display line shows the signal current. A value larger than 22 mA
(e.g. 25 mA) indicates a clogged or bent measurement line to the buried tank.
Please blow through or replace the measurement line, preferably with the blue
bubbling-through pipe of the e-litro set.
As a TEST the bubbling-through pipe can be disconnected from the LITRO-Sensor.
E8 should disappear with the next pumping action. Otherwise the LITRO-sensor is
defective or it has too much pressure.
Error
E 9
The current value is 0 mA. The probe
’s connection could be broken.
Check probe connection (polarity) and extension and if necessary reconnect it.
Error
E10
Calibration error. Switch off and on the 230V supply voltage after waiting for 5 sec
and retry. Otherwise the LITRO-sensor or the sensorbox is defective.
Error
E11
Warning: The liquid level of the tank is too low for an exact calibration
(Press [Enter] to continue anyway).
Error
E12
No measurement data is received yet from the external tanks 2, 3 or 4.
In case of
secu4
the sensorbox has not sent any data yet. Wait for 3 min.
Error
E13
No measurable pump pressure. Disconnect the current supply then reconnect it and
wait for one pumping cycle. If the error E13 remains the micro pump is defective.
Otherwise send in the LITRO-sensor or the sensorbox!
The device is not repairable on site. Do not open the device, loss of warranty!
Error
E14
Charging voltage is too low. Wait for 3 min. If necessary disconnect the power
supply for 10s.
Error
E15
No data from the sensorbox. Potential disruption of the signal line to the sensorbox.
Error
E16
Implausible pressure drop of one of the tank measuring lines (please check!).
Disconnect the power supply for 10s or cancel E16 with OK.
Otherwise the sensorbox is defective.
Error
E18
Device function error. The internal test pressure was not reached!
The sensorbox of the secu4 or the LITRO-sensor has to be replaced.
