8.1 Error message shown on the display (industrial version only)
The display shows up to three error messages with the highest priority. The following
table lists the messages that can be shown on the display. If a warning message is
active, the sensor continues to function in normal mode. If an error message is active,
the sensor goes into the error state. As soon as no error is present, the sensor automat-
ically switches back to normal operation.
Message Level Cause Solution
Supply Voltage too low Warning The supply voltage is too low. Check the supply voltage and, if
necessary, adjust it according to the
specifications (see “11 Technical
data” ).
Supply Voltage too high Failure The supply voltage is too high. Check the supply voltage and, if
necessary, adjust it according to the
specifications (see “11 Technical
data” ).
Low Voltage IO-Link Info The supply voltage is < 16 V, IO-Link
communication is no longer possible.
Check the supply voltage and, if
necessary, adjust it according to the
specifications (see “11 Technical
data” ).
Simulation is active Info The simulation function is active. The
status of the outputs does not corre-
spond to the actual measured flow or
temperature in the process.
If necessary, deactivate the simula-
tion function.
Failure Simulation is active Info The "Safe State" simulation of the
sensor is active. The status of the
outputs corresponds to the safe
state of the device.
If necessary, deactivate the simula-
tion function.
MemoryInvalid Failure Device memory contains an invalid
configuration. The sensor goes into
the safe state.
Please contact SICK.
Outputdriver Error No.70 Warning Output driver for the switching out-
puts is too warm.
Connect a suitable load (see 11
“Technical data” ) or reduce the
ambient temperature according to
the specification (see “11 Technical
data” ).
Outputdriver Error No.86 Failure Configuration of the analog output is
lost, analog output no longer func-
tions correctly.
Please contact SICK.
Outputdriver Error No.89 Failure Output driver for the switching out-
puts is much too warm. Sensor goes
into the safe state, the outputs are
switched off.
Connect a suitable load (see “11
Technical data” ) or reduce the
ambient temperature according to
the specification (see “11 Technical
data” ).
Outputdriver Error No.91 Failure Configuration of the switching
outputs is lost, switching outputs no
longer function correctly.
Please contact SICK.
Q1 Shortcut Info Short circuit or overload at Q1. Reduce the load at the output to
the maximum values according to
the specification (see “11 Technical
data” ).
