8Malfunctions
8.1 Diagnostics via LED
LED display Possible cause Remedy
Yellow Green Red
Fault in power supply. Connect power supply.
Fault in connecting cable. Replace connecting cable.
Device is faulty. Replace device.
All LEDs are off.
Hardware error. Switch power supply on/off.
Replace device.
Yellow LED is off.
Green LED is off.
Red LED is flashing.
Short circuit or overload at the
switching output.
Eliminate short circuit or over-
load.
Parameter error. Reset device to factory setting .
Yellow LED flashes at 3 Hz.
Communication error in IO-Link
mode.
Check IO-Link master.
Restart communication.
Check C/Q line.
Yellow LED flashes at 3 Hz
Green LED flashing at 1 Hz
Tab. 6: LED displays in case of malfunctions
If the device detects an error during IO-Link operation, a status message is output
at the IO-Link master. The IO-Link/switching output is not blocked.
8.2 General malfunctions
Malfunction Cause Remedy
Incorrect or unexpected signals
at the analogue output or with
the IO-Link process data.
Drive is not suitable. Use a suitable drive.
Device is faulty. Replace device.
No power supply or impermis-
sible operating voltage.
Maintain operating voltage
range.
Malfunction Cause Remedy
Incorrect or unexpected signals
at the analogue output or with
the IO-Link process data.
Short circuit or overload at the
switching output.
Eliminate short circuit or over-
load.
Magnetic object in the imme-
diate vicinity of the position
transmitter.
Do not place magnetic objects
in the immediate vicinity of the
position transmitter.
Sensor or drive was rotated
180° after initial commis-
sioning.
Reset to factory setting using
the operating key or via IO-Link.
Incorrect or unexpected signals
during initial commissioning on
grippers or in attachments with
ferromagnetic components.
On initial commissioning, move
gripper jaws or piston within
the sensing range, e.g. to both
end positions.
Switching output does not
switch in accordance with the
settings.
Short circuit or overload at the
switching output.
Eliminate short circuit or over-
load.
Device is faulty. Replace device.
Settings cannot be edited. Access protection is active. Unblock operating key (only
possible via IO-Link).
Tab. 7: Possible malfunctions
9 Disassembly
1. Switch off the power supply.
2. Disconnect connections from the position transmitter.
3. Unscrew the retaining screws è Fig. 3.
4. Remove the position transmitter from the T-slot of the drive.
