The warp detector, which is located above the warp lines at the rear section of the weaving machine, detects warp break to stop the machine operation. If a warp 1 breaks, dropper 2 falls down so that contact bar 3 draws current whose signals are transmitted via contact bar holder 4 and cable 5 to the machine control box.
 
NOTE: When handling contact bar 3, take special care not to bend it.
Failure to observe this may lead to a detection failure/error.

 
NOTE: Tighten the knob bolt 6 completely.
(The energizing circuit is connected by completely tightening the knob bolt 6. If it is loose, a detection failure/error may result.)
