9 Troubleshooting
9.1 General faults, warnings, and errors
Possible faults and corrective actions are described in the table below for troubleshoot‐
ing. In the case of faults that cannot be rectified using the information below, please
contact SICK Service. To find your agency, see the final page of this document.
NOTE
Before calling, make a note of all type label data such as type designation, serial
number, etc., to ensure faster assistance.
Question/Problem Possible causes/troubleshooting
The device does not display
a measurement or meas‐
urement is not possible.
•
Measuring laser not activated: Switch on the measuring laser.
•
Laser light spot is not aimed at object: Check alignment of the
device and correct if necessary.
•
Make sure that the light path is clear. Ensure that the object is
within the measuring range.
•
Ensure that the receiver element of the device is receiving
enough light.
•
Reflective surfaces: Check surface condition.
The device is being oper‐
ated in an EMC disturbed
environment.
Recommendation: Use data output via IO-Link. If measured values
must be output via the analog output, use an analog current
output. The analog current output is significantly less susceptible
to electromagnetic interference than a voltage output.
Measurement data show
anomalies.
The viewing window of the device is contaminated: Clean the view‐
ing window.
Measuring laser is
switched off.
Ensure the laser is switched on in the device settings.
Measuring laser remains
off despite correct setting
in the device settings.
The voltage supply to the device was interrupted and re-estab‐
lished within 4seconds: Wait 4seconds before re-establishing the
voltage supply to the device.
Device is connected to the
voltage supply but does not
switch on.
The voltage supply to the device was interrupted and re-estab‐
lished within 4seconds: Wait 4seconds before re-establishing the
voltage supply to the device.
The display shows an error
code: 0x…

9.2 Troubleshooting integrated IO-Link devices
Notes on malfunctions can be found in the service data.
Details of the available service data can be found in the detailed IO-Link description.
9.3 Detecting and displaying errors
In addition to measurement errors, the device can also detect and display other errors.
These are output as error codes via the display, SOPAS ET or IO-Link.
The device has an error memory in which internal error states of the device are
recorded. The last error that occurred is saved. The contents of the error memory are
retained when the device is switched off and when the Factory reset function is used.
