7 Troubleshooting
Table 3: Fault diagnosis
Display, error situation Cause Measure
Green LED flashes IO-Link communication
Digital outputs not according
to graphic IO-Link communication
Digital outputs not according
to graphic Parameter settings made
manually, which deviate from
the standard Initiate a factory reset. The digi‐
tal outputs are reset to factory
settings.
Yellow LEDs flash at the same
time The sensor is not ready for
operation. The sensor will be
in the warming-up phase at
low ambient temperatures.
The sensor will have shut
down at excessively high
ambient temperatures. At low ambient temperatures,
wait until the sensor has
warmed up. Ensure the sensor
cools down at excessively high
ambient temperatures.
Yellow LED flashes (only
briefly) Teach-in mode Check the teach-in mode
Yellow LED flashes fast, laser
is off, ISDU 36 shows "out
of specification" and one of
the events "Temperature too
high" / "Temperature too low"
is output. The device enters the no-oper‐
ate state as it is operated
outside the specification (too
high/low temperature). Operate the device only within
the specification.
