short overview on the subject of risk assessment; users of integrated safety
technology are obliged to intensively study the respective standards and legal
status.
The risk assessment carried out provides you the requirements for
determining the category for safety-related control units according to the valid
C-standard the safety-relevant parts of the machine control have to comply
with.
For more detailed information on the required Safety Integrity
Levels (SIL) and Performance Levels (PL), please refer to the
applied component- and machine-relevant standards in "
relevant standards and regulations
Procedure
To obtain the highest possible degree of safety, the machine manufacturer
when choosing the solutions has to apply the following basic principles in the
indicated order:
1.
Eliminate or minimize the hazards by construction measures.
2.
Take the required protective measures against hazards that cannot be
eliminated.
3.
Document the remaining risks and inform the user of these risks.
Simplification by use of integrated
safety technology
When using integrated safety technology, the machine manufacturer will
benefit from the following simplifications:
●
The safety-related parts of the IndraDrive Cs range with the options "L3"
and "L4" are suited for applications up to SIL3 of IEC 62061 and up to
Category 4, PL e of ISO 13849; i.e., the optional safety technology
modules of the IndraDrive Cs range allow implementing safety functions
which comply with SIL1, SIL2 or SIL3 of IEC 62061.
The safety-related parts of the IndraDrive Mi range with the option "L3"
are suited for applications up to SIL3 of IEC 62061 and up to
Category 4, PL e of ISO 13849; i.e., the optional safety technology
modules of the IndraDrive Mi range allow implementing safety functions
which comply with SIL1, SIL2 or SIL3 of IEC 62061.
The safety-related parts of the IndraDrive C and IndraDrive M ranges
with the option "L3" are suited for applications up to SIL3 of IEC 62061
and up to Category 4, PL e of ISO 13849; i.e., the optional safety
technology modules of the IndraDrive C and IndraDrive M ranges allow
implementing safety functions which comply with SIL1, SIL2 or SIL3 of
IEC 62061.
The safety-related parts of the IndraDrive ML range with the option "L3"
are suited for applications up to SIL3 of IEC 62061 and up to
Category 4, PL e of ISO 13849; i.e., the optional safety technology
modules of the IndraDrive ML range allow implementing safety functions
which comply with SIL1, SIL2 or SIL3 of IEC 62061.
