European Standard Illuminated Laser Warning Signs

(see also laser safety labels and laser interlocks)

 

Reduce interruptions and downtime in your
laser facility with accurate indication of laser status

All Class 3B and Class 4 lasers require interlocking to comply with standard safety practice. However, while this fulfills the safety requirements it can be annoying and even costly to have your laser shut down when an access door is opened. Such interruptions can be avoided either by using a locking interlock system (see ICS-1 brochure), or by providing accurate information regarding your laser status by the use of illuminated signs, or both.

Signs which are left on continuously even when the laser hazard is not present, quickly become ignored, so it is important to use a system incorporating automatic switching. This can be accomplished either directly from the ICS-1 laser interlock control system or by use of the LCU-1 light control unit. Various options are shown below with standard sign panels, but any message can be displayed as required.

Type	Size (mm)	Weight	Power rating (230 V)	Automatic switching from ICS-1	Automatic switching from LCU-1
One-way sign	360x150x120	2.5 kg	1 x 8 Watt tube	Yes	Yes
Two-way sign	360x300x120	5.2 kg	3 x 8 Watt tubes (two in red section)	Usually (depends on configuration)	Yes
Three-way sign	360x425x120	6.7 kg	4 x 8 Watt tubes (two in red section)	No	Yes
