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 17. 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

LBK SBV System 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:
Access detection function: access of one or more persons to a hazardous area deactivates the safety
l
outputs to stop the moving parts of the machinery.
Restart prevention function: prevents unexpected starting or restarting of the machinery. Detection of
l
motion within the dangerous area maintains the safety outputs deactivated to prevent machinery
starting.
It performs the following additional safety functions:
Stop signal: force all the safety outputs to OFF-state.
l
Restart signal: enables the controller to switch to ON-state the safety outputs related to all the detection
l
fields with no motion detected.
Muting (see Muting on page 47).
l
LBK SBV System is suitable for protecting the entire body for the following applications:
dangerous area protection
l
mobile dangerous area protection
l
indoor and outdoor applications
l
LBK SBV System meets requirements of applications safety functions that require a risk reduction level of:
up to SIL 2, HFT = 0 according to IEC/EN 62061
l
