ABSTRACT:
A process to test the monitoring function of an electronic sensor at the work station of a textile machine in order to avoid wrong decisions by the control unit of the work station. The sensors are tested during operation. For a brief time span a second sensor of the same type is located at the same time within the operating range of the sensor of the working station so that its function overlaps in time with that of the sensor of the work station. During the time of overlap the logical levels of the two sensors are detected, compared with each other and classified as result of the test.
