Concept 

 
The  Lasermet  LS-200 Laser  Safety  Shutter  is  intended  to  provide a means  of  preventing  accidental 
exposure to a potentially harmful laser beam. 
 
When  open,  the  laser  beam  passes  in  clear  air  through  the  shutter.  When  closed,  the  shutter 
deflects the incoming laser beam out of a separate port onto which a suitable external beam dump 
must be fitted. 
 
The shutter has been designed to form part of a high-integrity safety system and features a gravity-
close blade and force-disconnect proving contacts. 
 
A ‘SIL3’ dual version is available which, when correctly wired to a Lasermet Interlock Control System 
can provide a safety interlock which meets SIL-3 and EN13849-1 up to performance level ‘e’. 

 

Lasermet  provides  a  full  range  of  laser  interlock  equipment  including  control  systems,  interlock 
switches,  illuminated  warning  signs,  laser  shutters,  door  locks,  external  power  supplies  etc.  which 
can be connected to provide a complete laser interlock system. Full support, design and installation 
is available from Lasermet, please contact us for any queries. Contact details are given at the end of 
this manual. 
 
 

3.1  Control Options 

 
The shutter is usually powered by a laser interlock system such as Lasermet ICS-6. These systems will 
provide  power  to  allow  operation  of  the  shutter  once  all  safety  interlocks  (for  example,  doors, 
covers  etc.)  have  been  closed.  If  the  interlock  system  is  tripped  out,  the  shutter  will  immediately 
close. It then cannot be opened until the interlock system is re-armed. 
 
The shutter may be wired to operate in one of three different ways: 
 

1)

 

The Arming of the interlock system enables operation of the shutter. The buttons on top of 
the shutter may then be used to open and close it as desired. 

2)

 

The Arming of the interlock system enables operation of the shutter. The shutter may then 
be remotely opened and closed by external controls or buttons such as Lasermet’s LS-20 LS-
RS units. The buttons on top of the shutter may also be used. 

3)

 

The arming of the interlock system causes the shutter to open immediately. 

 
The shutter may also be wired into bespoke custom systems. 
 
The  shutter  operates  on  24VDC  and  draws  typically  200mA  when  open  and  40mA  when  closed. 
There is an initial impulse of approximately 1A on opening and the specification of power supplies 
and cabling must take this into account. 
 
SIL3 shutters draw twice as much current as standard units. 
 
Note that the LS-200 will not operate on 12V systems as used for older LS-10 and LS-100 shutters. 
Lasermet interlock systems can be reconfigured to provide the necessary 24V.
