Beacon lights often rise a little more than just illuminating a dark environment. In modern factories nowadays, beacon lights are considered critical, since these devices also help with safety and automation.

Beacon Lights For People And Machine Safety

In a dark setting, reliable lighting improves safety in a way that people are able to act and react according to what is happening around them. In the case of machines, beacon lights work as an indicator of their status. It shows if the machine is working smoothly or it needs attention when errors occur.

Machines that do not specifically require people to operate them are also equipped with beacon lights for smoother operation. Different colours of beacon lights indicate different messages that operators and other industrial workers can read. For example, green lights show that a machine is running perfectly. Yellow or Amber colour usually indicates some sort of warning, and red means that there is an error in the machine that needs attention.

Given that an industrial environment is an incredibly hazardous setting, the safety of people must be enhanced. High-Quality lighting has always been critical in guaranteeing that all workers have a clear vision of their surroundings as well as the equipment in the area.

In highly-automated sectors, the main risk is to keep people away from the work envelope of robots and machines. For this reason, most facilities that are highly-automated also integrate advanced safety precautions such as sensors and indicator lights.

Beacon And Stack Lights For Added Safety

Just like beacons, stack lights or tower lights are also used to increase safety in a particular place. They also come with different colours providing almost the same messages.

These colour-coded indicator modules that are stacked on top of each other show a tower-like structure, which is why this device is known as stack lights.

Stack lights can consist of up to five colours, including, red, amber, blue, green, and white. Red indicates failure conditions and amber or yellow usually indicate warning conditions such as over-pressure and over-temperature. On the other hand, green stack lights mean that the machine is in its usual condition. It means that the process is running smoothly and that operators have nothing to worry about.

Better Automation And Higher Productivity

Beacon lights have an undeniable contribution to the advancement of the stages of automation. It is the major reason why industrial environments require these lighting systems.

Stack or beacon lights allow the workers and operators in these busy facilities to work with confidence, given that they are well aware of what is happening during a machine process. On the side of operators, the use of these lighting systems helps them to understand the situation and decide on what to do next in order to keep the smooth flow of the work.

Final Say

In any industrial environment, an effective lighting system is very important. This need will become greater in the future because of the expanding world of automation in industrial environments. People who are involved in such environments feel safer and more productive because of the clear indications of machine status.

Stacking Beacons and Their Application

Stacking Beacons and Their Application






Stacking beacons are also known as indicator lights, signal tower lights, industrial signal lights, warning lights, Andon lights, light towers, and tower lights. They are most commonly used on equipment in process control environments and industrial manufacturing to deliver audible and visual indicators of a process event or machine state to machine operators, production managers, technicians, and factory personnel.


Different Application of Stacking Beacons

Just like typical beacon strobes or lights, stacking lights are used to relay a warning or essential message to a broad audience. They have the same application as beacons, but the information they provide encompasses more process or machine conditions.

Mostly, stack lights come with an LED, incandescent, or xenon-type strobe light source. They generally display columnar structures in different shapes, positioned on top of one another while having colour-coded indicator segments. Their name came from the way they are positioned, in a ‘stacked’ orientation.

It is more common for stack lights to have up to five different coloured segments to display different conditions on a process or machine. They can include red, green, yellow or amber, blue, and clear white. Also, these lights are sometimes static (solid-on) or flashing.

Here are some of the typical applications of stacking beacons:

Lean manufacturing – A systematic method that comes from the Japanese manufacturing industry that aims to minimize the waste in a manufacturing system.

Productivity monitoring – Stacking beacons are also used to monitor productivity in machine environments by uptime and downtime monitoring. It is also utilized to observe overall equipment effectiveness.

Assembly station workcells – In a manufacturing environment, stacking beacons are used for assembly stations during the arrangement of resources to optimize speed, quality, and cost of the process.

CNC machining equipment as well as process monitoring and feedback – Different colours of stacking beacons allows people around a machine operation and process to determine the status of the process.

Broadcast studios – Just like its other applications, stacking beacons are used in broadcasting studios to show statuses such as when the studio is on air, phone calls, live microphones, and doorbell within places that require silent indication.

How do Stacking Beacons work?

Stacking beacons are dubbed as passive devices that can be controlled using distributed control systems, PC control systems, programmable logic controllers, or hardwired into machine controls like sensors, timers, and latching relays.

Here are the commonly used stacking beacon colour codes for machine state conditions:

  1. Yellow or Amber – For machine state conditions, yellow or amber indicates warning messages, including over-pressure or over-temperature conditions.
  2. Red – Just like a traffic light, red stacking beacons mean emergency stop or it may mean failure conditions like machine fault.
  3. Blue – When you see a blue stacking beacon flashing or solid-on, it means an external help request. It might indicate that an operator is requesting raw materials, maintenance personnel assistance, or scheduling.
  4. Green – The green light for machine operations shows that the process is at a normal condition of flow.
  5. White – This light shows user-defined conditions to a particular machine. It is mostly related to productivity monitoring.
