Your machine speaks in colour. 1 to 5 tier LED signal tower — machine status visible from anywhere in the shop floor.
A CNC machinist should not have to walk to a machine to know if it is running, faulted, or idle. A 3-tier tower light — green running, amber attention, red fault — tells every person in the bay the machine status at a glance from 20 metres away.
Tower lights (also called stack lights or Andon lights) are the standard machine status indicator in automotive plants, CNC machining centres, and assembly lines across India.
