LED/fault pattern Cause Measures
Green LED does not light up Voltage interruptions outside
the permissible range Ensure there is a stable
power supply in accordance
with the technical specifica‐
tions
Green LED flashes IO-Link communication -
Digital outputs not according
to graphic Parameter settings made
manually, which deviate from
the standard
Initiate a factory reset. The
digital outputs are reset to
factory settings.
Signal interruptions when
object is detected Difference between the
switch-on and switch-off
threshold (=hysteresis value)
is too small and/or the fluc‐
tuation of the light reflected
by the object is too large
for the configured hysteresis
value.
Increase the hysteresis value
