Figure 1 - Thread Break Sensor Test Design
The thread break sensor test design is helpful to check the thread break sensor to make sure it is sensing thread moving on the thread break sensor bar. The AMAYA reports thread breaks if the thread break sensors attached to the bar do not detect thread running against it when it should be. If there is a valid thread break, the AMAYA OS ( AMAYA OS) should report a thread break (no thread running against the sensor bar). Conversely, if there are no thread breaks, there should be no thread break reports. Cut the thread where it runs into the needle a few times to see if valid thread breaks are detected properly. There should be no thread breaks or pull outs other than those that you initiated deliberately for testing purposes. Also, there should be no inconsistency in the fill portion of the design.
The thread break test should be sewn on one layer of white broad cloth (Melco PN: 344754-01) (or any white polyester material) or equivalent with one layer of backing (ARC PN: C20162210).
