TROUBLESHOOTING
Error code
Significance
Error E1
The set value is invalid
Error E2
Measured value too small (I < 3.7 mA
probe defective)
Error E3
Measured value too great for zero point calibration (level probe must not be
immersed)
Error E4
Measured value not plausible. Check menu item “9.Offset probe”
Error E5
Set height is more than the height of the tank. (incorrect entry menu step 10)
Error E6
The current measured value is too low as a reference point. The level probe
must be submerged. The set height (menu step 10) is too high (the
measured value is too low) Check menu item "9. Offset probe".
Error E7
The current measured value is too low in relation to the set tank height or to
the tank volume. The level probe must be submerged.
Error E8
Measured value (probe current) is too high - check electrical connection and
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.
Error E9
Probe current = 0 mA - no signal current. The probe cable is poled wrongly
or interrupted; check cable extension, reconnect if necessary.
Error E10
Calibration error. Disconnect the display device from the power supply, wait
5 s and then reconnect.
Error E11
The liquid level in the tank is actually too low for an exact
measurement. You can still press [Enter] to confirm and continue.
Error E12
(Still) no measured value available from external tank 2..4
only SmartBox 4 LAN.
Errors in the network connection/data transfer
Error N1
No network communication - problem with the internal network adapter.
The device automatically resets the adapter and tries to address the plug-in
adapter again.
To test, unplug or check the network cable.
Error N2
Error in network communication. Check the device cables and the connection
to the network router.
Check the parameters, menu item "15.Network".
Execute the function "Network > Test > Ping: Yes".
As a test, connect a different network device, such as a laptop.
If necessary, ask your network administrator for advice.
Error N2 is reported only for defined reporting destinations, such as
www.smart-inspector.com. If an individual destination IP is entered, there will
be no N2 problem message:
Important: The destination address must be a fixed IP. Otherwise, the device
will keep trying to send with the display test "Send Data..." because the IP
address is not reached.
