The sensor can be used in standard I/O mode (SIO) or IO-Link mode (IOL). All automa‐
tion functions and other parameter settings are effective in IO-Link mode and in stand‐
ard I/O mode (exception: time stamp). Output of binary switching signals in standard
I/O mode via pin 4 / black wire or via pin 2 / white wire.
Information on the IO-Link functions can be found in the enclosed IO-Link photoelectric
sensors operating instructions or downloaded from www.sick.com under the device
order number.
WTF9-3P2261S01: Photoelectric proximity sensor with foreground suppression, max.
sensing range 500 mm, switching frequency 200 Hz
WTF9-3P3011S05, cable with MOLEX male connector
The Troubleshooting table indicates measures to be taken if the sensor stops working.

OPERATING INSTRUCTIONS
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
IO-Link communication
IO-Link communication
Parameter settings made
manually, which deviate from
the standard
Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal
Distance between the sensor
and the background is too
short
Distance between the sensor
and the object is too long or
sensing range is set too short

Measures
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Ensure there is a stable power
supply without interruptions
If the power supply is OK,
replace the sensor
-
-
Initiate a factory reset. The
digital outputs are reset to
factory settings.
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
background. / Clean the opti‐
cal surfaces . / Readjust the
sensitivity (potentiometer) /
Check sensing range and
adjust if necessary.
Reduce the sensing range
Increase the sensing range
