Behavior of the device in the event of a fault

The device displays warnings and faults via IO-Link. All the device warnings and faults are
for information purposes only and do not have a safety function. The errors diagnosed by
the device are displayed via IO-Link in accordance with NE107. Depending on the
diagnostic message, the device behaves as per a warning or fault condition. A distinction
must be made between the following types of error here:
• Warning:
– The device continues measuring if this type of error occurs. The output signal is not
affected (exception: simulation is active).
– The switch output remains in the state defined by the switch points.
• Fault:
– The device does not continue measuring if this type of error occurs. The output signal
assumes its fault state (switch outputs de-energized).
– The fault state is displayed via IO-Link.
– The switch output changes to the "open" state.

Resetting to factory settings (reset)

Reason
Electronics/sensor defective
Load current > 200 mA
Overload at switch output 2
When the simulation of a switch
output or current output is
active, the device displays a
warning.
Switch point/switchback point
are too close together or inter-
changed.
Sensor check failed
Sensor check
Timeout reed contact
Ambient temperature outside of
specification

Corrective measure
Replace device
Increase load resistance at
switch output
• Check output wiring
• Replace device
Switch off simulation
• Check probe coverage
• Perform configuration again
• Repeat cleaning
• New calibration recommen-
ded and check switching
behavior
• Replace device
