3 SAFETY
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 page 16
.
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
safeRS3 is certified SIL 2 according to IEC/EN 62061, PL d according to EN ISO 13849-
1 and Performance Class D according to IEC/TS 62998-1.
It performs the following safety functions:
l
Access detection function
: access to a hazardous area deactivates the safety
outputs to stop the moving parts of the machinery.
l
Restart 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 optional safety functions:
l
Stop signal: force all the safety outputs to OFF-state.
l
Restart signal: enables the control to switch to ON-state the safety outputs related to
all the protective fields with no motion detected.
l
Muting (see
).
safeRS3 is suitable for protecting the entire body for the following applications:
l
dangerous area protection
l
mobile dangerous area protection
l
indoor and outdoor applications
safeRS3 meets requirements of applications safety functions that require a risk
reduction level of:
l
Up to SIL 2, HFT = 0 according to IEC/EN 62061
l
Up to PL d, Category 3 according to EN ISO 13849-1
l
Up to Performance Class D according to IEC/TS 62998-1
safeRS3, in combination with additional risk reduction means, can be used for
applications safety functions that require higher risk reduction levels.
The following is deemed improper use in particular:
l
Any component, technical or electrical modification to the product,
l
Use of the product outside the areas described in this document,
l
Use of the product outside the technical details (see
).
