9.1 Diagnostics via LEDs
LED Possible cause Remedy
Yellow Red
Both LEDs OFF
Power supply, connecting cable or sensor is
faulty/defective (there may not be a fault
è
Tab. 5 LED Displays in the Proximity Sensor
Operating Mode).
– Check power
supply.
– Check connecting
cable, replace if
necessary.
– Replace device.
Permanently:
Short circuit/overload at the switching output – Rectify short cir-
cuit/overload.
Yellow LED flash-
ing at 3 Hz For 3 s, after pressing the capacitive operating key:
capacitive operating key is blocked. – Cancel the block
on the capacitive
operating key
using the IO-Link.
Red LED flashing
at 3 Hz
Hardware error – Switch the power
supply off and
then on again.
– Replace device.

9.2 General Malfunctions
Fault description Cause Remedy
Drive is not suitable. Use a suitable drive.
Device is faulty. Replace device.
No power supply or impermiss-
ible operating voltage. Comply with operating voltage
range.
Short circuit or overload at the
output Rectify short circuit/overload.
Magnetic objects in close prox-
imity to the position transmitter Avoid positioning magnetic
objects in close proximity.
Sensor/drive rotated by 180°
after initial commissioning. Reset to factory settings (using
the operating key or via IO-
Link).
Incorrect or unexpected signals
at the output
Incorrect or unexpected signals
during initial commissioning on
grippers or in attachments
which are partly ferromagnetic On initial commissioning, move
gripper jaws or pistons within
the sensing range (e.g. at both
end positions).
Short circuit or overload at the
output Rectify short circuit/overload. Switching output does not
switch in accordance with the
settings.
Device is faulty. Replace device.
Settings cannot be edited. Access protection is active. Unblock operating key (only
possible via IO-Link).
Capacitive operating key does
not react to input. Dirt or moisture on the position
transmitter Wipe position transmitter with a
dry cloth.

10 Disassembly
1. Switch off the power supply.
2. Disconnect connections from the position transmitter.
3. Undo the hexagon socket-head bolts
è Fig.5.
4. Remove the position transmitter from the T-slot of the drive.
