andon

Andon (アンドン, あんどん, 行灯) is a manufacturing term referring to system to notify management, maintenance, and other workers of a quality or process problem. The centrepiece is a signboard incorporating signal lights to indicate which workstation has the problem. The alert can be activated manually by a worker using a pullcord or button, or may be activated automatically by the production equipment itself. The system will include a means to stop production so the issue can be corrected. Modern alert systems will incorporate audio alarms and text or other displays.
