LS-200 Instruction Manual
Note for correct operation, installation wiring should use at least 16/0.2mm wire to avoid problems
of voltage drop on the wiring run. On very long distances, when using 'SIL3' shutters, or in situations
where two shutters may be connected simultaneously 24/0.2mm wire may be advisable for the 24V
supply wires.
For other options including the use of illuminated signs in conjunction with the shutter please
discuss your requirements with Lasermet.

Installation
The shutter baseplate has two mounting slots and a pair of M6 threaded T- nuts are provided which
are loaded into the slots through the beam entry and exit ports.
The slots allow for mounting and adjustment on a variety of standard optomechanical breadboards
as well as custom mounting. The slots are aligned with the beam centreline.
Both slots should always be used. Dimensions are given at the end of this manual.
The shutter has a through aperture of Ø50mm. The beam and beam dump ports are threaded M52 X
0.75mm. Lasermet can provide custom containment tubes and adaptors to order. Please contact us
for details at the address at the end of this manual.
Ensure that the laser beam is travelling in the direction of the arrow shown on the top of the shutter.
See the section, 'Dimensions' later in this manual.
5.1 SIL-3 Version LS-200-SIL24
To achieve EN13849-1 performance level 'e' the 'SIL3' version must be used wired as shown in
diagram 2. The 'SIL3' version is a twin unit which has one shutter behind another. Both shutters
must be open to allow the beam to pass through.
In this unit one set of monitor contacts is dedicated to one of the shutters, the other contact to the
other shutter, so the state of both blades can be monitored. When correctly interfaced to a
Lasermet ICS, the interlock system cannot be armed if either one or both blades are not detected
closed.
5.2 Blade and Beam Dump Options
It is vital that the external beam dump is mounted as close as possible to the shutter and that the
beam path is suitably contained to avoid risk of exposure.
Lasermet produce an air-cooled beamdump specifically for the LS-200 shutter, part number BD200-
AC.
