Setting
The capacitive sensor is provided with a switching output with an adjustable switching point.
The sensor switches automatically to normal operation after the teach-in operation is success-
fully completed. The time interval between two teach-in operations can be any length.
The device can only be parameterized via IO-Link.
NOTE
The taught in value is rejected if a determined switching point is outside of the
assured switching distance. The device indicates an error and returns to normal
operation without any changes.

Settable functions and features
Parameter
Meaning
Application Specific Tag
The specific application can be described in which the sensor is used.
Parameter (write) Access Lock
Access to the device parameters is locked or unlocked.
Device Reset
The command restarts the device. Communication is interrupted momentarily.
Application Reset
The function resets application parameters. Communication is not interrupted
and the sensor is switched to a predefined operating state. Identification
parameters are not affected by this command.
Restore Factory Settings
The function restores the device to the factory setting. The device is restarted
after the reset. Communication is interrupted.
Reset diagnostic information
All diagnostics information of the device is reset to the factory setting. The
counter of the switching operations and the maximum and minimum of the
sensor signal are also reset.
Sensing mode
The device offers three modes with different scan rates:
n
Standard (100 Hz)
n
Accuracy (10 Hz)
n
Speed (200 Hz)
Switching output mode
The switching output can be configured as a PNP or NPN output. The PNP output
is active by default.
Function
The switching output can be set either as an NO contact or as an NC contact.
NO contact is active by default.
Hysteresis value
The size of the hysteresis window can be set in % (10 % or 20 % of the maximum
sensor signal).
Current switching point
The current switching point can be set manually. It is also possible to view the
current switching point.
Switching output switch-on
delay
The switch-on of the switching output can be delayed.
Switching output switch-off
delay
The switch-off of the switching output can be delayed.
Single Value Teach start
The single value teach-in is started. The current process value is calculated here
and is set as the switching point. A value below the switching point activates the
switching output. The process value range is from 0…5000, with 0 correspond-
ing to the possible full scale of a detected object.
Two Value Teach without object
(teachpoint 1)
The two-value teach-in is started. Perform teach-in without object in front of the
sensor. The result is stored in the
Teach point
parameter.
Two Value Teach with object
(teachpoint 2)
Perform teach-in with object in front of the sensor. If both teach points are
present, the teach-in can be started via the
Two Value Teach apply
parameter.
