6 Operation
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.
NOTE
For basic instructions for the display and control elements see "Control elements and
status indicators", page 17. Briefly pressing the pushbutton changes from the
measured value display to the menu level.
For the overall menu structure see "Menu structure", page 84.
6.1 General notes
If the sensor is unable to measure, adjust the measuring speed or optimize the align‐
ment.
For a successful teach operation, the sensor must be able to measure. The distance
to the teach object must not change during the teach operation. The object must be
in the measuring range, and the distance values taught in for the near-sensor distance
and far-sensor distance must not be exactly the same during a switching window or the
analog scaling.
To prevent EMC interference, observe the wiring instructions. If an environment is
disrupted by EMC interference, data output via IO-Link is the preferred solution. If the
application requires an output of the measured values in such an environment via the
analog output, an analog current output should also be preferred to using the voltage
output, because this is significantly less susceptible to EMC interference.
NOTE
The switching mode and the settings can be changed by executing a teach function by
means of a multifunctional input (see "Multifunctional input (“MF Input”)", page 57) or
IO-Link (see "Operation via IO-Link", page 21).
NOTE
The LEDs, the process data bits of the outputs in IO-Link and the output visualization
in SOPAS display the logical status of the outputs. This does not necessarily correspond
to the electrical level of the switching 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.
