The Error Proofing (Andon System) is a visual and audio line-status communication system that displays information about the current conditions of the production line. It alerts team members, team leaders, and maintenance and management personnel of a problem at a specific job site and also serves as a tool to call for assistance.  

When an operator requires assistance, the operator pulls/activates the “pull cord” at that work area. Based on the configurations for your facility, a pull cord can activate the Error Proofing, activate an indicator light at the operator station, can indicate the request for help on the Andon board, and can sound a team-specified musical tune to attract attention. When the team leader or supervisor hears the music alert, the Andon message board cell location can indicate the section with the problem. Then the team leader goes to that section and calls for any extra personnel, if necessary, to solve the problem. After problem resolution occurs, personnel pull the cord again to return the system to the normal operation. Again, based on the configurations at your  facility, if problem resolution does not occur before it reaches a fixed position stop (FPS), the conveyor will stop. With a problem resolution before it reaches the fixed position stop, the system will return to normal operation without stopping.
