setting is active via IO-Link
communication.
►
Stop IO-Link
communication before
parameter setting on the
sensor.
S.Loc X
Setting buttons locked
via parameter software,
parameter change rejected.
►
Unlocking the sensor
via parameter setting
software.
W530 X
Analogue output at the lower
limit (3.8 mA).
►
Reduce ASP value if
possible (for [OU2]
= [InEG] AEP value)
or increase system
pressure.
W532 X
Load at analogue output too
high.***
►
Reduce load at output
2 or increase the supply
voltage.
W203 X
Error during the temperature
compensation of the pressure
measurement.
The unit uses a higher
temperature coefficient (i.e.
with reduced accuracy).
►
Replace the unit.
W703 X
Medium temperature too high
(> 150 °C).
Reduce the medium
temperature.
W704 X
Medium temperature too low
(< -30 °C).
Increase the medium
temperature.
W161 X
Unit temperature too high (>
90°C).
Unit outside the
specification.
►
Do not insulate the
installation.
W162 X
Unit temperature too low (<
-30 °C).
Unit outside the
specification.
►
Insulate the installation.
* In case of undervoltage (fault no. W403) nothing is displayed.
