Andon tower light

Machine status, in colours the whole floor can read

An Andon tower light is a stack of coloured LED lights on a machine or line. Each colour carries its own message, so operators and supervisors see what needs attention the moment it happens.

01Overview

What is an Andon tower light?

A visual signalling device for the shop floor. It shows the status of a machine, production line or process as light, so problems are seen, and acted on, the moment they occur. Its bright LEDs stay clear even in well-lit areas, and it can be connected to sensors, PLCs and other control devices to show status automatically.

What it does for the line

  • 01

    Status at a glance

    Every machine's state is visible from across the floor, without walking up to a screen.

  • 02

    Issues found sooner

    A problem shows the moment it happens, so the right team knows where to go.

  • 03

    Less downtime

    Faster responses mean machines spend less time stopped.

  • 04

    One signal for every team

    Operators, maintenance and supervisors read the same light and the same colours.

  • 05

    A safer workplace

    Clear visual warnings for hazards, machine faults and emergency situations.

  • 06

    Lean by design

    Andon is a core lean practice: make a problem visible, then stop and fix it.

02Colour code

One colour for each machine status

Each tier carries its own message. These are the colours on our call stations; you configure which alarm each one raises.

  • Fault

    Red

    The machine has stopped with a fault.

  • Maintenance

    Yellow

    Maintenance is called for, or under way.

  • Running

    Green

    The machine is running as it should.

  • Quality

    Blue

    A quality check is called at this machine.

  • Custom

    White

    Set it for any other alarm your line needs.

An audible alarm can be added, so a call is heard as well as seen.
