LED Meaning
Color Function State
Green Power indicator On The sensor is operating normally. The required
operating voltage is available.
Flashes
(900 ms on : 100 ms off)
IO-Link communication is active.
Yellow Function indicator On 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
a
1)
.
Flashes
(250 ms on : 250 ms off)
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
n
of typically 6 mT.
►
Check whether the sensor still detects the set
switching point after a temperature change and
reset the switching point if necessary.
Red Fault indicator On
(green and yellow LEDs
are off )
A hardware error was detected. This may be caused
by the following:
– Excessive load current on the switching output (I
load
+5 %)
– Output driver too hot (T
driver
≥ 125 °C)
– Sensor supply voltage too low (U
B
on L+ < 6.5 V)

field strength over the entire temperature range, measured axially in the
slot base.
