The Major/ Minor/ Length Selector version offers a detection of big slubs with stoppage of the Warping machine. Small slubs are counted and the machine is stopped when a certain number of small slubs is detected related to a pre-set warping length.

The setting of the tolerance is done by the operator: To give an example, the Warping machine will be stopped if the tolerance of 20 small slubs on a warping length of 100 meters is exceeded.
