WERMA Signal Towers and Signal Elements

Several states at a glance

Signal towers indicate the status of machines and plants using several signal elements stacked on top of each other. This makes it easy to see, even from a distance, whether a machine is running, a warning is active or a fault needs to be cleared. With modular WERMA signal towers you combine the elements as required and can extend the tower later or replace individual elements.

Signal elements and selection criteria

• Light elements: steady, flashing and strobe light elements, as LED versions or for the wide voltage range 12–230 V AC/DC.
• Audible elements: siren elements with 8 tones and voice output elements that make messages audible.
• Signal colours: red, yellow, green, blue and clear; the number and order of elements depend on the states to be displayed.
• Operating voltage: for example 24 V DC, 24 V AC/DC, 115 V AC or 230 V AC – the same for all elements of one tower.
• Assembly: in addition to the elements, a complete signal tower requires a connection or base element and, where needed, a tube, bracket and end cap.

Frequently asked questions

In which order are the colours arranged?

Red at the top is common, followed by yellow and green; blue and clear are added as needed. The standards and company rules applicable to your machine are decisive.

Can I extend an existing signal tower?

With modular systems, elements of the same series can be added or exchanged. Make sure the series and voltage match.

What is a voice output element used for?

It announces messages as spoken information, making it clear what needs to be done – helpful when several similar signals could otherwise be confused.
