9.2.1 Diameter detection
The actual winding diameter is detected by a Sensor and provided
to terminals 1 and 2 of the controller as an analog Signal 0 - 1OV.
This Sensor tan either be used in non-contact Operation (e.g.
ultrasonic, Optical Sensors) or in sampling Operation (e.g. sampling
Potentiometer).
The non-contact Sensor detects the distance between the Sensor
and the circumference of the winder and transmits the Signal to the
controller. The internal program tan detect the actual winding
radius also in this case.
