11TROUBLESHOOTING
11.2 Operating the display
Error Cause Solution
Expert mode is
activated
IO-Link communication active
Menu does not
open
IO-Link Device Access Locks active See “8.5.5 Locking the display without a password”.
The display only
shows Passwd
Display lock activated with password entry See “8.5.6 Locking the display with a password”.
11.3 Outputs
Error Cause Solution
Switching output
does not behave as
expected
Conguration incorrect Check the conguration of the switching output
(see “8.3 Conguring the switching outputs”).
Error signal at switching output that is congured
as input. Sensor is in a safe state
If a switching output is congured as an input,
check the signal and the system if required.
Cable break Check the cable.
Analog output does
not behave as
expected
Conguration incorrect Congure the analog output
(see “8.4 Conguration of analog outputs”).
Error signal at switching output that is congured
as input. Sensor is in a safe state
If a switching output is congured as an input,
check the signal and the system if required.
Cable break Check the cable.
IO-Link communica-
tion not possible
Input is set under Q1Mode Set output under Q1Mode.
11.4 Error behavior
Error Cause Solution
Level display does not change Insufcient signal quality Perform empty adjustment, see “8.5.4
Performing empty adjustment”.
Probe is contaminated Clean the probe.
Easy Clamp used Perform empty adjustment, see “8.5.4
Performing empty adjustment”.
The displayed level value is greater than
SPx/RPx/FHx/FLx/QxLow/QxHigh
An offset was congured for the level
value
Adjust offset, see “8.5.11 Setting the
offset”.
Level is uctuating Media surface unsettled Activate ltering, see “8.5.8 Filtering
measured values”.
Strong EMC interferences Activate ltering, see “8.5.8 Filtering
measured values”.
Level is not detected,
sensor (at times) indicates too low a
level (< 50 mm), although a high level
is present.
Threshold is set too high Check SigQu1 and reduce the threshold
until a good signal is emitted.
The empty state of the probe has
changed signicantly due to altered
ambient conditions or aging
Check SigQu4, perform empty adjust-
ment if required, see “8.5.4 Performing
empty adjustment”.
