11.1 Error message on the display
Error Cause Solution
!InvEc &
level present
AutCal not executed, source of interference super-
imposed on medium reection
Perform commissioning
(see “7.1 Quick commissioning (with factory
settings)”).
TrsHld setting is not suitable for the medium Perform advanced commissioning
(see “7.2 Advanced commissioning”).
!InvEc &
empty tank
Probe length congured incorrectly Check probe length and compare against congu-
ration in EXPRT-Cong-LENGTH
Probe not available Check probe
!ATTNT A parameter was written outside of the valid value
range and therefore was adjusted
Rewrite the value in the valid range.
Another parameter was automatically adjusted
due to a dependency (SPx, RPx)
Check the parameter again.
!WRONG Incorrect password entered Enter the correct password.
!NoCal Information: The AutCal process and/or foam
calibration was rejected because the probe length,
teach-in depth, or measuring mode was changed.
Repeat commissioning if necessary.
!Denid AutCal was accessed in the Foam sensor mode AutCal is only available in Pulse mode Perform
foam calibration in Foam mode
CalPIs No valid calibrations for CalEmp and CalMed Perform foam calibration
!CalOk The teach-in process was successful
!NoSig AutCal failed Repeat commissioning.
!faild Foam-CalEmp or FoamCalMed menu item failed Follow the foam commissioning instructions
!SC-Q1
!SC-Q2
!SC-Qa
Short circuit at the output Remove short circuit
Load resistance at the output is too low Increase load resistance
!IOLOf Supply voltage too low for IO-Link communication Increase supply voltage to achieve the desired
functionality
!QaO Supply voltage too low for analog output Increase supply voltage to achieve the desired
functionality
!QxO Supply voltage too low for switching outputs Increase supply voltage to achieve the desired
functionality
!QaOvf The ohmic load at the analog current output Qa is
too high
Reduce the load at Qa
The analog current output Qa is not wired. Connect the load to Qa
!MaskZ Interference / pulse exceeds value for MaskTr. Increase MaskTr or identify and remove source of
interference.
!Range The maximum allowable measuring range was
exceeded. Measurement in this conguration is
not possible.
Reduce probe length and/or coaxial cable length,
see “8.4.10 Changing the coaxial cable length”.
!Cable The coaxial cable is damaged/faulty Replace the coaxial cable
The coaxial cable length was congured incorrectly See “8.4.10 Changing the coaxial cable length”.
