Improve lean production methods with Andon switch box

In the language of lean production methods an Andon light commonly refers to any sort of visual system (signal tower or traffic light system)which will alert staff to danger in the workplace, a change in status of a machine or process or as a simple "call for action”.

When used as a "call for action” the andon light needs to be manually activated by the member of staff at the workstation. For example, a simple four colour andon light might signify:

• Green onWorkstation manned.

• AmberAssistance required from maintenance.

• RedSerious error, supervision required.

• BlueMaterial shortage – stores to replenish.

A flexible call system

A workstation equipped with a signal tower and an andon box allows the member of staff to call immediately for help without leaving the workstation. Local visibility of the "call for action” is given by the signal tower which may also be equipped with a sounder for additional effect.

Easy to install

The andon box is a switch box and is supplied with the essential cabling to link it to theandon light or signal tower and a plug in 24V power supply unit.

Wireless technology provides a complete overview 

In larger production areas workstations are often outside the supervisor’s line of sight. For situation such as these WERMA offers an optimal solution: a combination ofAndonBox and WIN (Wireless Information Network) allows a central overview of the currents status of up to 50 workstations at the same time. By adding a WIN transmitter to the signal tower operated by the andon box every time a switch is actuated that data is collected by the WIN system allowing review and performance monitoring of the workstation.
