2.5. Sensor Specific adjustable parameters
Besides the parameters directly related to output configuration, the sensor also have various internal parameters
useful for setup and diagnostics.
2.5.1. Selection of local or remote adjustment
It is possible to select how to set the sensing distance by either selecting the "Trimmer Input" or "Teach-by-wire"
using the external input of the sensor, or to disable the trimmer input by selecting "IO-Link Adjustment" to make
the sensor tamperproof.
2.5.2. Trimmer data
Value between 20 ... 225 mm for PD30CTB.20..., 20 ... 275 mm for PD30CTBS25... and 20 ... 375 mm for
PD30CTBR35...
2.5.3. Process data configuration
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, AFO1.
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.
NB! If Application functions are selected more options for "Analogue Values" can be selected in the Observation
tab.
2.5.4. Sensor Measurement Selection
The sensor has 3 sensor precision presets, which can be selected depending on the environment:
• Default precision (Filter scaler fixed to 1)
• High precision (Filter scaler fixed to 10 - slow)
• Customized (Filter scaler can be set from 1-255)
Precision can be adjusted via parameter "Filter scaler". See 2.6.9.
2.5.5. 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.
2.5.6. Safe limits
The Safe limits can be set for the sensor in % of the SP1 and SP2 and can be set individually for SSC1 and
SSC2. It is used for calculating a Stable ON or Stable OFF signals.
• Dust alarm: If the Safe limits are exceeded then the dust alarm is activated, see also Dust alarm description
• The Green LED is also influenced by the Safe limits and can be used to set up the sensing distance manually
adjusting until the LED lights Stable ON.
2.5.6.1. Stable ON
When the sensor detects a signal that are x % higher (set by Safe limits) than the value for which the output
switches ON, then the sensor is stable ON.
2.5.6.2. Stable OFF
When the sensor detects a signal that are x % lower (set by Safe limits) than the value for which the
outputs switches Off, then the sensor is stable OFF.
