Introduction This section describes the safety performance level concept and explains
how the Guardmaster 440G-LZ meets the requirements for SIL 3, Cat. 4 or
Performance Level “e” (PLe) applications.
Safety Certification The Guardmaster 440G-LZ is certified for use in safety applications up to
and including SIL 3 according to IEC 61508 and IEC 62061 with a proo
f test
interval of 20 years, Performance Level PLe and Category 4 in compliance
with ISO 13849-1.
Safety requirements are based on the standards applicable at the time of
certification.
The TÜV Rheinland group has approved the Guardmaster 440G-LZ for use
in safety-related applications where Performance Level “e” is required for
the door position and lock monitoring functions.
The 440G-LZ must be installed in accordance with the applicable
regulation and standards.
While the 440G-LZ can be used for SIL 3, PLe and Category 4 applications,
the installer must comply with guard requirements (e.g. EN/ISO13854
and EN/ISO 13857) and in some cases also minimum (safe) distance
requirements (e.g. EN/ISO 13855).
