Object Combi Sensor A/B
Function Selecting the sensor to be used for guiding (SensorA or SensorB).
This object is used if the web guiding system is equipped with one or two combination
sensors. With a combination sensor, two different sensor types can be selected for
scanning the web edge (e.g. ultrasonic edge sensor and optical edge sensor).
When changing from a transparent to an opaque material, for example, the function
allows the scanning to be switched from an ultrasonic edge sensor (Sensor A) to an
optical edge sensor (Sensor B).
