Error codes / error display
Message
Meaning
Error E 1
Invalid input value.
Error E 2
Measuring value of the probe is too small !
If current is less than 3.7 mA => Probe error.
Error E 3
Measuring value is too high for zero-point calibration or offset calibration.
The probe must not be plunged !
A probe current higher than 4.3 mA indicates a defective probe.
Error E 4
Call step ‘9.Offset probe’ and perform the calibration once. Then retry settings.
Error E 5
‘Height’ input is larger than tank height. (Wrong input.)
Error E 6
The measuring value is too small for reference. Make sure the probe is plunged.
Settled height is too large (or means the measuring value is too small for setting).
Execute step ‘9. Offset’. If it doesn’t work check the probe current (mA) !
Error E 7
The current measuring value is too small for the corresponding tank height or
the volume input value. Make sure the probe is plunged.
Error E 8
The current measuring value (mA) is too high. Check electrical connection and
check the measuring range of the probe. Switch 230V supply off and on.
Check input steps 1 to 5. Execute the zero-point calibration again (=> ‘9.Offset
probe’) and check step ‘22.Test current.’ Otherwise replace the measuring probe.
Error E 9
The current value is 0 mA. The probe’s connection could be broken. Check probe
connection (polarity) and extension. Measure the voltage at the probe (red to black).
Error E10
Calibration error. Switch off and on the 230V supply voltage and retry.
Otherwise the probe is working not properly.
Error E11
Warning – The liquid level in the tank is too low for an exact calibration.
(Press [Enter] to continue anyway.)
Error E12
No measurement data is received from the external tanks 2 ... 4 yet.
