Application example:
During application setup it is possible to take account of this by reading out the Quality parameter regularly
to determine its lowest value. Then the threshold Nominal value quality parameter can be set 1-2 levels
lower. If the Quality parameter drops below this threshold for any reason during operation, this is indicated.
At that moment the application still works properly, however the sensor should be checked some time.
Possible reasons for activation of the Quality parameter may be:
Sensor is soiled → Sensor must be cleaned
Sensor has been moved → Readjust sensor
Something in the application has changed, e.g. varying object surface finishes → Readjust
sensor (Nominal value quality parameter) if necessary.
With the aid of this function, it is possible to detect sensor failure at an early stage and take appropriate
action.
Important: The sensor still functions properly even with a Quality parameter of 1. It is not absolutely
necessary to achieve the highest possible value!
