88 8014485/YE12/2014-08-20 © SICK AG • Level sensors • Germany • Subject to change without notice
Cause
AutCal not executed, interference
superimposes medium reflection
TrsHld setting is not suitable for the
medium
Probe length configured incorrectly
Probe not available
A parameter was written outside of
the valid range of values and therefore
adjusted.
Another parameter was automatically
adjusted due to a dependency (SPx,
RPx)
Incorrect password entered
Information: The AutCal process and/
or the foam calibration was rejected,
as the probe length, the teach-in
depth, or the measuring mode was
changed.
The teach-in process was successful
AutCal failed
Foam/CalEmp or Foam/CalMed failed. Follow foam commissioning instructions.
Short-circuit at the output
Load resistance at the output is too
low
Supply voltage too low for IO-Link
communication
Supply voltage too low for analog
output
Supply voltage too low for switching
outputs
The ohmic load at the analog current
output Qa is too high
The analog current output Qa is not
wired.
7 Troubleshooting
Solution
Perform commissioning
(see Chapter 2.1 „Quick commissioning")
Perform advanced commissioning
(see Chapter 2.2 „Advanced commissioning")
Check probe length and align with configurati-
on in EXPRT-Config-LENGTH
Check probe
Rewrite the value in the valid range.
Check the parameter again.
Enter the correct password.
Repeat commissioning if necessary.
Repeat commissioning.
Remove short-circuit
Increase load resistance
Increase supply voltage to achieve the desired
functionality
Increase supply voltage to achieve the desired
functionality
Increase supply voltage to achieve the desired
functionality
Reduce the load at Qa
Connect the load to Qa
