ERROR CODES
Error code
Meaning
Error E 1
Invalid value setup.
Error E 2
Measuring value of the probe is too low !
If current is less than 3.5 mA => Probe error.
Error E 3
Measuring value too high for probe offset/zero calibration. The probe must not be
plunged! A probe’s current above 4.5 mA is invalid as zero point.
Error E 4
Offset/zero calibration necessary for setup. Return to step 9 for calibration.
Error E 5
Set height is larger than tank height. (Wrong input.)
Error E 6
Current measuring value is too low as reference point. Make sure probe is plunged!
Level height setup is too large (=> measuring value is too small).
Execute again 9.Offset probe. Otherwise defect of probe!
Error E 7
Current measuring value too small for set corresponding tank height or
tank volume. Make sure probe is plunged.
Error E 8
Current measuring value (or mA) is too high. Check electrical connection and
check measuring range of the probe.
Switch 230V supply voltage off and on. Check setup steps 1 to 5.
Execute again 9.Offset probe. Otherwise defect of probe.
Error E 9
Current value is 0 mA. Check probe connection (polarity) and electrical extension.
Error E10
Calibration error. Switch 230V supply voltage off and on. Else defect of probe.
Error E11
Warning – The liquid level in the tank is too low for an exact calibration.
(Press OK to continue anyway.)
Error E12
Yet no measurement data is received from the external tanks 2 ... 4.
