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.
