Quality Of Teach Qot; Filter Scaler; Led Indication - CARLO GAVAZZI CA18CA Manuel D'instructions

2.6.8. Quality of Teach QoT

The quality of Teach value lets the user know how well the actually the tteach procedure was carried
out, in terms of the margin between the actual setpoints and the environmental influences on the
sensor.
The value for QoT can vary from 0 ... 255 %.
The QoT value is updated after every Teach procedure.
Examples of QoT are listed in the table below.

2.6.9. Filter Scaler

This function can increase the immunity towards unstable targets and electromagnetic disturbances:
Its value can be set from 1 to 255, the default factory setting is 1.
A filter setting 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 if it is disturbing to have the
LEDs lighting up in the application.

Excellent teach conditions, the sensor is not expected to have any
maintenance issues.
Good teach conditions, the sensor has been taught with a safety mar-
gin of twice the standard hysteresis.
• Long term reliability is expected for all environmental conditions.
• Maintenance is not expected to be required.
Average teach conditions.
• Short-term reliability and maintenance is expected due to environ-
mental conditions.
• Reliable detection can be expected with restricted environmental
influence.
Poor teach result.
• Unreliable working sensing conditions are expected. (e.g. too small
measuring margin between the target and the surroundings).
