11.1
Error message on the display
Error
Cause
Solution
!SC-Q{1,2,3,4}
!SC-Q{a,b}
Short-circuit at Q{1,2,3,4}
Q{a,b}
Remove short-circuit.
Load resistance at the output is too low
Increase load resistance.
!InErr
Error signal at switching output that is configured
as input. Sensor is in a safe state
!OLQ{1,2,3,4}
Overload at Q{1,2,3,4}
Reduce the load.
Reduce the ambient temperature.
!MFail
Memory error
The device is faulty and needs to be replaced.
!QxOff
Supply voltage too low for switching outputs
Increase supply voltage to achieve the desired
functionality.
!QaOff
Supply voltage too low for analog output
Increase supply voltage to achieve the desired
functionality.
!IOLOf
Supply voltage too low for IO-Link
Increase supply voltage to achieve the desired
functionality.
!Ovolt
Supply voltage too high
Reduce the supply voltage.
!HTmpH
!HTmpL
Sensor housing temperature too low/high
Adapt the ambient conditions.
!PTmpH
!PTmpL
Process temperature outside the specification
Adapt the process conditions.
!Temp
Process temperature measurement not possible
Contact service.
!Q{a,b}Ovl
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.
!Simul
At least one simulation (SimQ{1,2,3,4,a,b}, SimLvl,
SimTmp) is active
Deactivate the simulation.
!Signl
Signal quality 2 or 4 is too low (sensitivity to inter-
ference or quality of empty state); for example,
due to deposits or temperature drift
Probe must be cleaned,
tank components are too close to the probe or
CalEmp must be performed, see
.
!Trshl
Signal quality 1 is too low (sensitivity to threshold) The threshold is set too high for the current
medium,
the medium permittivity is too low.
!Attnt
Other parameters have been adapted automati-
cally.
E.g.:
- SPx changed, RPx corrected
- RPx changed, SPx corrected
- Offset changed, SPx/RPx/… corrected
!lockd
IOLink Local User Interface Access Locks activated Reset the Access Locks via IO-Link.
Press and hold the Set pushbutton for at least
10 seconds.
!Err{xx}
Internal error has occurred
Contact service.
