7 Operation
7.1 General notes
NOTICE
Pushbutton damage due to improper handling!
Improper handling of the pushbuttons can damage them. This will make operation
difficult or impossible.
■
Only operate the pushbuttons with your fingers or a suitable pointing device.
■
Do not operate the pushbuttons using sharp or hard objects.
If the device is unable to measure, you need to adjust the measuring speed or optimize
the alignment.
For a successful teach-in operation, the device must be in the orientation for measur‐
ing. The distance to the teach-in object must not change during the teach-in operation.
The object must be in the measuring range. For a switching window or analog scaling,
the distance value for near and far must not be identical.
To prevent EMC interference, observe the wiring instructions. If an environment is dis‐
rupted by EMC interference, data output using IO-Link is the solution. If the application
requires an output of the measured values in such an environment via the analog
output, an analog current output must also be used in preference to the voltage output.
This is significantly less susceptible to EMC interference.
NOTE
The LEDs, the process data bits of the outputs in IO-Link and the output visualization
in SOPAS display the logical state of the outputs. This does not necessarily correspond
to the electrical level of the digital outputs. The electrical level of an output depends on
the setting of the corresponding logic, the output circuit (NPN or PNP) and the logical
status of the output. The examples in this document refer to a PNP circuit.
