3.1.4 Safety assessment
Before using a device, a safety assessment in accordance with the Machinery Directive
is required.
The product as an individual component fulfills the functional safety requirements in
accordance with the standards stated in Standards and Directives on page17.
However, this does not guarantee the functional safety of the overall plant/machine. To
achieve the relevant safety level of the overall plant/machine’s required safety
functions, each safety function needs to be considered separately.
3.1.5 Intended use
safeRS/safeRS3 mixed system is certified SIL 2 according to IEC/EN 62061 and PL d
according to EN ISO 13849-1.
It performs the following safety functions:
lAccess detection function: access of one or more persons to a hazardous area
deactivates the safety outputs to stop the moving parts of the machinery.
lRestart prevention function: prevents unexpected starting or restarting of the
machinery. Detection of motion within the dangerous area maintains the safety
outputs deactivated to prevent machinery starting.
It performs the following additional safety functions:
lStop signal: force all the safety outputs to OFF-state.
lRestart signal: enables the control to switch to ON-state the safety outputs related to
all the protective fields with no motion detected.
lMuting (see Muting on page58).
safeRS/safeRS3 mixed system is suitable for protecting the entire body for the following
applications:
ldangerous area protection
lindoor and outdoor applications
The following is deemed improper use in particular:
lany component, technical or electrical modification to the product
luse of the product outside the areas described in this document
luse of the product outside the technical details, see Technical data on page113
3.1.6 EMC-compliant electrical installation
