2.6. Sensor Specific adjustable parameters

Besides the parameters directly related to output configuration, the sensor also have various internal
parameters useful for setup and diagnostics.

2.6.1. Selection of local or remote adjustment

It is possible to select how to set the sensing distance by either selecting the Trimmer or Teach-by-wire
using the external input of the sensor, or to disable the potentiometer to make the sensor tamperproof.

2.6.2. Process data and variables

When the sensor is operated in IO-Link mode, the user has access to the cyclic Process Data Variable.
By default the process data shows the following parameters as active: 16 bit Analogue value, Switching
Output1 (SO1) and Switching Output 2 (SO2).
The following parameters are set as Inactive: SSC1, SSC2, DA1, DA2, TA, SC.
However by changing the Process Data Configuration parameter, the user can decide to also enable
the status of the inactive parameters. This way several states can be observed in the sensor at the
same time.

2.6.3. Sensor application setting

The sensor has 3 pre-settings depending on the application:
• Full scale range, the setpoints of the sensor can be adjusted at full scale and the sensing
speed is set to maximum
• Liquid level: this is to be used for slow moving objects with a high dielectric value such as in
the detection of water-based liquids. When this function is selected the teach and
potentiometer settings are optimized to high range scaling.
In this mode the "Filter Scaler" is set to 100
• Plastic Pellets: this is to be used for slow moving objects with a low dielectric value such as in
the detection of plastic pellets. When this function is selected the teach and potentiometer
settings are optimized to low range scaling.
In this mode the "Filter Scaler" is set to 100.

2.6.4. Temperature alarm threshold

The temperature at which the temperature alarm will activate can be changed for the maximum and
minimum temperature. This means that the sensor will give an alarm if the maximum or minimum
temperature is exceeded. The temperatures can be set between -50 °C to +150 °C. The default
factory settings are, Low threshold -30 °C and high threshold +120 °C.
