TROUBLESHOOTING
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
“8.5.5 Locking the display without a password”.
The display only
shows Passwd
Display lock activated with password entry
“8.5.6 Locking the display with a password”.
11.3
Outputs
Error
Cause
Solution
Switching output
does not behave as
expected
Configuration incorrect
Check the configuration of the switching output
(see
“8.3 Configuring the switching outputs”
).
Error signal at switching output that is configured
as input. Sensor is in a safe state
If a switching output is configured as an input,
check the signal and the system if required.
Cable break
Check the cable.
Analog output does
not behave as
expected
Configuration incorrect
Configure the analog output
(see
“8.4 Configuration of analog outputs”
Error signal at switching output that is configured
as input. Sensor is in a safe state
If a switching output is configured 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
Insufficient signal quality
Perform empty adjustment, see
Probe is contaminated
Clean the probe.
Easy Clamp used
Perform empty adjustment, see
The displayed level value is greater than
SPx/RPx/FHx/FLx/QxLow/QxHigh
An offset was configured for the level
value
Adjust offset, see
Level is fluctuating
Media surface unsettled
Activate filtering, see
Strong EMC interferences
Activate filtering, see
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 significantly due to altered
ambient conditions or aging
Check SigQu4, perform empty adjust
