Main Unit 00629-00-000 Tandem Unit 00647-00-000 DECLARATION OF CONFORMITY This is to declare that the LS-20 and LS-20 SIL3 have been found to comply with the requirements of the following Directives and European Standards: Directives: Machinery Directive 2006/42/EC June 2010... -
Page 4: Safety Note
Be aware that once degradation starts to occur rapid failure is likely, possibly leading to the beam passing unhindered through the shutter. Due to the huge number of different types, powers and beam sizes of lasers Lasermet cannot guarantee suitability of this shutter in every case and testing may be necessary to ensure that the shutter provides the desired level of protection. -
Page 5: Concept
SIL3 shutters draw twice as much current as standard units. Note that the LS-20 will not operate on 12V systems as used for LS-10 and LS-100. Lasermet interlock systems can be reconfigured to provide the necessary 24V. -
Page 6: Indications
Wiring The LS-20 shutter is supplied with a permanently connected 3m lead terminated in a 15-way high density ‘D’ plug. The connector makes available all of the various control and indication features of both the standard and the ‘SIL3’... - Page 7 Lasermet produce a range of Distribution Boxes and Remote Switches fitted with sockets specially for use with LS-20, which provide convenient screw terminals to make installation neat and simple. Units are available in both free-standing and fixed installation versions and full wiring instructions are supplied with each one.
- Page 8 Monitor Contact 2 ‘Closed’ Monitor Contact 2 Common Diagram 2: Implementing a SIL-3 system using ‘SIL3’ LS-20 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...
- Page 9 Detailed Pin Descriptions The LS-20 shutter can be wired in various ways. The simplest configuration is to connect pins 10 and 12 to +24V and pin 1 to 0V. The shutter can then be operated using its buttons. Other pins may be connected as required giving a wide variety of control and monitoring options.

Page 10: Mounting And Beam Containment
The shutter has a through aperture of Ø16mm. The beam and beam dump ports are threaded M17 X 1. Lasermet can provide containment tubes and adaptors to order. Please contact us for details at the address at the end of this manual. -

Blade and Beam Dump Options The LS-20 beam dump is removable which allows an external beam dump to be used. This could potentially enable the shutter to be used with more powerful lasers than can be dissipated by the shutter itself. - Page 12 LS-20 Instruction Manual There are a number of mirror blade options featuring a front silvered or dielectric mirror for various wavelengths. These allow the shutter to be used with higher power lasers than the standard blade but note that an external beam dump will be required. The mirror blade option is also advisable when mounting a laser power meter at the beam dump port.

LS-20 Instruction Manual Using with Powerful Lasers If the blade or beam dump become overheated, they will be permanently damaged. Moreover, once damage has started to occur the situation is likely to deteriorate further unless immediate action is taken to turn off the laser. -
