8 Troubleshooting
Possible faults and rectification measures are described in the table below. In case
of faults that cannot be rectified using the information below, please contact the
manufacturer. See the back page for your agency.
General faults, warnings and errors
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. Warnings and errors are signaled by the Status LED. The Power LED
signals that the sensor is connected to the power supply.
8.1 Detecting and displaying errors
In addition to measurement errors (see "Behavior if no measurement is possible
(NoMeasurement)", page 65), the sensor can also detect and display other errors.
These are output by the display, Sopas ET or IO-Link.
Error memory
The sensor has an error memory where internal error states of the sensor are recorded.
The last error to have occurred is always saved. The contents of the error memory
are retained when the sensor is switched off and when the “Restore Factory Settings”
function is used.
