Safety of the machine or system
The machine/system manufacturer and the operator are solely responsible for the safety
of the machine or system and the implemented application, in which the machine or system
is used. The Machinery Directive must therefore be observed.
In order to use the safety module described in this document, you must have drawn up an
appropriate safety concept for your machine or system. This includes a hazard and risk
analysis according to the directives and standards specified in Section "Directives and
standards" on page 1-4, as well as a test report (checklist) for validating the safety function
(see "Appendix: Checklists" on page C-1).
VersaSafe: Please refer to the documentation for the configurable logic module used.
The target safety integrity level (SIL according to EN 61508, SIL CL according to EN 62061
or performance level and category according to EN ISO 13849-1) is ascertained on the
basis of the risk analysis. The safety integrity level ascertained determines how to connect
and parameterize the safety module within the overall safety function.
Within a VersaSafe or PROFIsafe system, the IC220SDL840 safety module can be used
to achieve safety functions with the following requirements:
–
Up to SIL 3 according to standard EN 61508
–
Up to SIL CL 3 according to standard EN 62061
–
Up to Cat. 4/PL e according to standard EN ISO 13849-1
Carry out a validation every time you make a safety-related modification to your overall
system.
Use your test report to ensure that:
–
The safe devices are connected to the correct safe sensors and actuators
–
The safe input and output devices have been parameterized correctly
–
The variables have been linked to the safe sensors and actuators correctly
(single-channel or two-channel)
1.4
Directives and standards
The manufacturers and operators of machines and systems, in which the IC220SDL840
module is used, are responsible for adhering to all applicable directives and legislation.
For the standards observed by the module, please refer to the certificate issued by the
approval body and the EC declaration of conformity. These documents are available on the
Internet at http://support.ge-ip.com.
