Sensing range is not able to be set. The sensor has been adjusted to the maximum
sensing range by the factory and is ready for operation.
IO-Link
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 and via pin 2 / white wire.
Information on the IO-Link functions can be found in the enclosed IO-Link photoelectric
sensor operating instructions or downloaded from
number.
The Troubleshooting table indicates measures to be taken if the sensor stops working.
