Faults
The following table describes possible faults and troubleshooting measures. 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 code, serial number, etc.,
to ensure faster processing.
General faults are subdivided into warnings and errors. Current measured values con‐
tinue being output when there are warnings; measurement is no longer possible when
there are faults.
Table 9: Troubleshooting questions and replies
Question / status
Response / remedial actions
The device does not display a meas‐
urement or measurement is not pos‐
sible.
•
Sender not activated: Switch on sender,
•
Laser light spot is not aimed at object: Check align‐
ment 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.
EMC disturbed environment
Recommendation: Use data output via IO-Link.
If measured values must be output via the analog out‐
put, use an analog current output. The analog current
output is significantly less susceptible to electromag‐
netic interference than a voltage output.
9.2
