Note:
The results of this assessment are valid when the following procedures are followed:
• The Relays of the VC-1100 have to be operated in the „normally energised” mode.
• The analog 4-20 mA signal industry-standard current loops must be used.
• The OK Relay has to be used as system function.
• The VC-1100 system must be protected against erroneous change in configuration
Abbreviations:
MTTF
Mean Time To Failure
PL
Performance Level
From PL "a" (highest failure probability) to PL "e" (lowest failure probability)
Category
Category (CAT)
Classification of the safety related parts of a control system in respect of their
resistance to faults and their subsequent behaviour in the fault condition, and
which is achiev ed b y the structur al arr ang ement of the parts, fault detection
and/or by their reliability
Ground Benign,
Controlled
Nearly zero environmental stress with optimum engineering operation and
maintenance.
Note:
The harmonized standard EN 954-1 is stil l va lid (end of 2011), but it is considered technically outdated. It
was replaced by the current harmonized standards EN ISO 13849-1. More detailed information about safety
and reliability values can be obtained on request from Brüel & Kjær Vibro (
