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 of the sensing distance by either select the Trimmer, 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
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 are set to maximum
•
Liquid level, is to be used for slow moving objects with a high dielectric value such as
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, is to be used for slow moving objects with a low dielectric value such as
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 where the temperature alarm will activate can be changed for the maximum and
minimum temperature. This means that the sensor will give an alarm in 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.
