What is Andon? - Definition from Whatis.com

An Andon is a visual control that indicates the status of a machine, manufacturing line or work process.  Andons are often accompanied by audible alarms to alert supervisors when there is a change in status. 

Adons are an effective way  to alert support personnel  who must attend to several automated processes at a time or are not always located in close proximity to the work they oversee.

ANDONS are typically color-coded this way:

  • Green - normal operations 
  • Yellow - attention will be required in the near future 
  • Red - urgent attention is needed.
