2.6.8. Quality of Teach QoT

The quality if teach value informs about how well the actually teach procedure was done, meaning

the margin between the actual setpoints and the environmental influence of the sensor.

The value for QoT can vary to any value from 0 ... 255 %.

The QoT value is updated after every teach procedure.

Examples of QoT is listed in the table below.

2.6.9. Filter Scaler

This function can increase the immunity towards unstable targets and electromagnetic disturbances:

Value can be set from 1 to 255, the default factory settings is 1.

A filter settings of 1 gives the maximum sensing frequency and a setting of 255 gives the minimum

sensing frequency.

2.6.10. LED indication

This parameter allows the user to disable the LED indications in the sensor in case it will be disturbing

to have the LEDs lightening up in the application.

Excellent teach conditions, the sensor is not expected to require any

maintenance issues

Good teach conditions, the sensor has been taught with a safety mar-

gin of two times the standard hysteresis.

• Long term reliability is expected for all environmental conditions.

• Maintenance is not expected to be required.

Average teach conditions.

• Short-tern reliability and maintenance is expected due to environ-

mental conditions.

• Reliable detection can be expected with restricted environmental

influence.

Poor teach result.

• Not reliable working sensing conditions is expected. (e.g. too small

measuring margin between the target and the surroundings).
