Meaning
The sensor is operating normally. The required
operating voltage is available.
IO-Link communication is active.
The switching point has been reached and the
switching conditions are met provided no fault is
detected. The axial magnetic field (measured by the
sensor at the bottom of the slot) is ≥ 6.5 mT and
thereby corresponds to the assured magnetic
switching field strength H .
1)
a
The switching point has been reached and the output
is switched. The measured magnetic field strength is
however sufficient only for operation under the current
ambient conditions and the current sensor
temperature, and corresponds to the rated switching
field strength H of typically 6 mT.
n
► Check whether the sensor still detects the set
switching point after a temperature change and
reset the switching point if necessary.
A hardware error was detected. This may be caused
by the following:
– Excessive load current on the switching output (I
+5 %)
– Output driver too hot (T ≥ 125 °C)

– Sensor supply voltage too low (U
