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:
DATALOGIC LASER MARKERS
The Machinery Directive 2006/42/UE, EN 13849-1 and EN ISO 11553-1 are NOT applica-
ble to Datalogic Laser Markers.
Datalogic, in order to help customers in their approval process, as a voluntary act, has
applied in its laser marker, where possible, some points of above mentioned regula-
tions.
The examples of this appendix relate only to the features introduced in Arex™ XXX-X6X
models to assist in the laser radiation risk reduction.
CAUTION
Any other risks (mechanical, electrical, etc.) must always be evaluated and
appropriate risk reduction measures taken where necessary.
The target safety integrity or performance level (e.g. PLd according to
ISO13849-1) shall be determined by the customer, taking into account the
machinery directive, the harmonized standards and any sector-specific
standard that may apply.
