Appendix B. Safety Consideration According To En Iso 13849-1:2008; Performance Level (Pl); Application Example - Datalogic UniQ 1150-1X41 Product Reference Manual

APPENDIX B
SAFETY CONSIDERATION
ACCORDING TO EN ISO 13849-1:2008

PERFORMANCE LEVEL (PL)

The PL is specified in EN-ISO13849-1. The risk analysis will lead to a PLr (Performance
Level required) for a safety function based on the following graph:

Application example

Figure 51: Determining the required Performance Level (PLr)
CAUTION: These examples relate only to the features introduced in UniQ™
to assist in the risk reduction from the laser radiation. Any other risks
(mechanical, electrical, etc.) must always be evaluated and must be taken
appropriate risk reduction measures where necessary.
The Machinery Directive and EN 13849-1 are NOT applicable to the product
UniQ™.
The target safety integrity or performance level (e.g. PLd according to
ISO13849-1) shall be determined by the machine integrator, taking into
account the machinery directive, the harmonized standards and any sec-
tor-specific standard that may apply.
CAUTION: These examples are based on the parameters indicated on para-
graph "Safety Functions of UniQ™" on page 83.
