Shine a Light on Machine Status

The new Modlight Pro light stacks outshine the competition

Every company needs to ensure that its machines and systems are being properly utilized with maximum run-times since, idle machines and plant downtimes don’t contribute to economic success. As a result, production strives to keep downtime to a minimum. In order to intervene as quickly as possible, it’s important to be able to clearly signal process statuses.

This is true for both routine processes as well as unscheduled or unforeseen events. These signals must be so clear that they can be detected easily, even in high pressure or high stress situations. In these cases, most plants turn to state-of-the-art signal towers that use colors that people already associate with certain situations.  Pedestrian cross walks are a perfect example. They use green for walk and red for don't walk. Moving that concept into the plant, every machine operator recognizes that machines with green signals are running normally while red ones indicate a potentially dangerous situation.

Under some circumstances, its necessary to use more than just a visual signal to communicate current status to machine operators. The building’s environment or its lighting situation may make it difficult to visually discern what is going on. In such cases, audible signals are essential. They are another way to increase awareness of a particular situation. They assist the operator in taking the first step towards reducing the length of a downtime period.

Murrelektronik’s Modlight Pro light stacks allow a user to assemble up to five color elements in the configuration of their choice. In addition to red and green, the lights are also available in yellow, blue and white. The additional colors are great for indicating of process statuses in accordance with the IEC 60204-1 machinery specifications and with a choice of either a 50 or 70mm diameter they can be sized to fit the application.

The lights twist together quickly and easily - no tools are needed. The connection terminals are color coded and represent the color of the light to help reduce the risk of assembly errors. Or you can purchase a preassembled Modlight Pro stack light in a commonly used color combination.

Bulb replacement is a thing of the past thanks to the use of innovative and energy-saving LEDs. The LEDs have a long life - at least 40,000 hours at full brightness. Even after that, the brightness of the lighting is only slightly reduced, which is scarcely perceptible to the human eye. This means that these towers remain maintenance-free over the life of a machine saving both time and money!

Modlight Pro also offers a buzzer module that can be incorporated if you need an audible signal. The buzzer attaches to the Modlight Pro at the top of the stack replacing the cover. The buzzer is designed to be clearly audible with adjustable volume up to a maximum of 90 dB ensuring that the signal can still be heard clearly, even in a loud environment. Changing the position of the dip switch lets you select one of four tones for each stack light.

Modlight Pro light stacks are IP65 rated. Comprehensive approvals and vibration resistance allow you to use them worldwide. They can also be ordered with a plug-in M12 connector or a magnetic base. Either allows a stack to be mounted quickly and temporarily removed for transportation.
