Error code
Significance
The set value is invalid
Error E1
Measured value too small (I < 3.7 mA probe defective)
Error E2
Measured value too great for zero point calibration (probe must not be
Error E3
immersed)
Measured value not plausible. Check menu item "9.Offset probe"
Error E4
Set height is more than the height of the tank. (incorrect entry menu step 10)
Error E5
The current measured value is too low as a reference point. The probe must
Error E6
be submerged. The set height (menu step 10) is too high (the measured
value is too low) Check menu item "9. Offset probe". Otherwise, probe fault.
The current measured value is too low in relation to the set tank height or to
Error E7
the tank volume. The probe must be submerged.
Measured value (probe current) is too high - check electrical connection and
Error E8
measuring range of the probe, switch power supply off and on again. Check
menu settings steps 1 to 5. If necessary, Check menu step "9.Offset probe".
Otherwise, probe fault.
Probe current = 0 mA - no signal current. The probe cable is poled wrongly
