Fault rectification
The first measure to take is to check the output
signal. In many cases, the causes can be de-
termined this way and the faults quickly rectified.
Reaction after fault rectification
Depending on the reason for the fault and the
measures taken, the steps described in chapter
" Setup" must be carried out again or must be
checked for plausibility and completeness.

Diagnosis, fault messages

Checking the switching signal
The 360° status indication on the device indi-
cates the operating status of the device. At the
same time it indicates the switching state of the
output. This enables simple on-site diagnosis
without the need for tools.
Error Cause
Green signal Voltage
lamp off supply inter-
rupted.
Electronics
defective
Green signal Maintenance
lamp flashes required
Red signal Error with the
lamp lights electrical con-
(switching nection
output high-
Shortcircuit or
impedance)
overload
Measuring tip
damaged
Red signal Sensor out-
lamp flashes side the
(switching specification
output high-
impedance)
Sensor is in

Rectification
Check voltage supply
and cable connection
Exchange the instru-
ment or send it in for
repair
Carry out mainte-
nance
Connect device ac-
cording to wiring plan
Check electrical con-
nection
Check whether the
measuring tip is da-
maged
Check sensor adjust-
ment.
Switching points may
be interchanged.
Terminate simulati-
on mode
You can read out the error codes from
the IO-Link data.
Under "Device Status" (ISDU 294) you
can find the status of the device.
Failure/Error
Red control lamp lights up
Error Cause
F013 no measured
value availa-
ble
F080 General soft-
ware error
F105 Measured
value is deter-
mined
F111 Switching
points inter-
changed
F260 Error in the
calibration
F261 Error in the
instrument
settings
Out of specification
Red signal lamp flashes
Error Cause
S600 Electronics
temperature
too high
Rectification
Error in the elect-
ronics
Restart instrument
If the error occurs
again, replace the
device
Restart instrument
Device is still in the
switch-on phase.
Wait until the device
is ready for operation.
Repeat sensor adjust-
ment.
The switching point
(SP) must be smaller
than the reset point
(RP).
Repeat device adjust-
ment.
If the error occurs
again, replace the
device
Carry out device re-
set.
Reset device to deli-
very status.
Rectification
Error in the elect-
ronics
Allow device to cool
down and restart
If the error occurs
again, check the am-
bient temperature
