Display
The switching state display (yellow) is illuminated
when the output is active.
With IO-Link devices, the switching function is
defined via the
"Switch Point Mode.Logic"
parameter.
The power on display is constantly illuminated in
normal operation. If there is a malfunction, for
example overload at the output, the display
flashes.

Display during calibration.
Calibration
The switch point can be taught via the DI (Data
Input) teach input for either empty or full vessel
conditions.
For a full calibration, the switch point is set below
the current sensor value. That way, the active
status can be recognized even if there are slight
changes in the application.
Accordingly, for an empty calibration the switch
point is set above the current sensor value.
In most applications, full calibration is usually
sufficient. For a secure switch-off despite any
present residues and build-up, empty calibration
can be performed in critical applications.
Calibration via te ach line (DI input)
Calibration is started by connecting the DI input to
L+; the switching threshold is adopted when
removing the DI input from L+. The type of
calibration is determined based on the duration;
the process is displayed via the function LED (see
Display during calibration
).
w
Full calibration: Connect the DI input to L+ for
2 to 7 seconds
w
Empty calibration: Connect the DI input to L+
for 7 to 12 seconds
If the DI input remains connected to L+ for longer
than 12 seconds, the calibration process is
aborted. The switching threshold is not changed.
To start a new calibration, the DI input must be
removed from L+.
®
For IO-Link devices, the DI teach input can be
deactivated via the
"Device Access Lock. Local
parametrization"
parameter.
Display during calibration
•
During the full calibration (2 to 7 seconds
after DI active) the ready LED flashes slowly.
The switching state LED is OFF.
•
During the empty calibration (7 to 12 seconds
after DI active) the ready LED flashes slowly.
The switching state LED is ON.
•
If the calibration is successful, the switching
state LED flashes slowly three times. During
this, the ready LED is OFF.
•
If the calibration process is canceled (DI active
for longer than 12 seconds) or if there is an
error, the switching state LED flashes quickly
several times. During this, the ready LED is
OFF.
Calibration for object recognition
Move the object into the desired switching range.
Observe the permissible detection range of the
sensor as well as reduction factors depending on
the application!
