Safety Performance
Standard LS-200
EN ISO13849-1:2008 performance level ‘c’
LS-200 SIL-24
EN ISO13849-1:2008 performance level ‘e’
IEC 61508-1 SIL 3
when correctly wired to a suitably rated control system.
The LS-200 SIL-24 is a dual channel electromechanical safety laser shutdown device.
System Type
Type A System
Hardware Fault Tolerance
1
When connected to an interlock control system as shown in this manual, the LS-200SIL-24 has the
following characteristics. This can also be achieved by correctly connecting to another suitable safety
control system which has dual channel monitoring of the shutdown device.
Safe Failure Fraction
95%
PFD
1.56 x 10-7
When used as described above, the LS-200SIL-24 is suitable for use as the sole laser shutdown device
in a system which is required to achieve Safety Integrity Level 3 (SIL 3) or lower as defined in IEC
61508.
Note:
The actual SIL rating of the entire system will depend on the other system components, how
they are connected together and how the system is used.
Reliability
Mean time to dangerous failure (MTTF
d
)
100 years
Number of operations after which 10% of units have failed (B10
d
)
> 1 x 10
7
It is important to note that the Performance Level established for the LS-200 are those that may be
achieved by the system when the board is properly integrated into a safety related part of a control
system.
