Display and operating elements
Output LED (BOS 18K...PD/PE/XA/QC/
QD/RE/TB/FR/1N1R, BLE 18K...)
The yellow LED ON indicates that the NO
output status is closed.
Stability LED (BOS 18K...PD/PE/QC/QD/
FR, BLE 18K...PP)
The green LED ON indicates that the
received signal has a reserve greater than
30% compared to the output switching
value.
Power on LED (BLS 18K...1P)
The green LED indicates that the sensor is
operating.
Potentiometer (BOS 18K...QD/PD/PE/
TB/FR, BLE 18K...PP)
The potentiometer can be used to adjust
sensitivity; the operating distance increases
turning the potentiometer clockwise.
Notice!
The potentiometer rotation is limited to
270° by a mechanical stop.
Do not apply excessive torque when
adjusting (max 40 Nm).
Test Function (BLS / BLE)
