3 MSR300 System: Product and Applications Overview
3.1
Safety Standards and Safety Relay Functions
Note: In this document, the word "standard" can mean a defined industry standard, EU
directive, technical statute or regulation.
The safety standards relevant to this product and its application are outlined in brief in
Section 3.1.2 below.
General
The MSR300 Safety System is intended for applications requiring safety monitoring of
machinery in accordance with the following directives / standards:
• EN954-1: Safety-Related Parts Of Control Systems; up to Category 4.
• IEC 61508: Functional Safety of Electrical / Electronic / Programmable Electronic
Safety-Related Systems, Parts 1-7, 1998; level SIL 3.
An MSR300 System will conform to these standards provided external devices connected
to it, overall system and safety design, and installation practices conform to appropriate
standards.
This equipment must not be used for unintended applications, nor in
ways that do not conform to appropriate safety standards and good
practices. The safety functions may not operate properly (or at all) if
this equipment is not used for the intended purposes.
This product, the equipment on which it is installed, persons handling
the product and equipment, and/or the immediate environment can
be harmed if this equipment is operated outside the specified limits of
any of its technical parameters.
Electrical safety regulations stipulated by the appropriate technical
authorities must be observed.
Machine safety applications make it necessary for hazardous areas
and dangerous operating modes to be carefully identified, and
adequate measures taken to ensure that failure or tampering does
not allow automated equipment to be of risk to personnel.
It must be understood that use of safety monitoring and control
devices such as this product is not sufficient to ensure that the
equipment on which it is installed will meet the relevant stipulated
regulations and directives. The design and reliability of the machinery
on which this product is used, the proper selection and co-ordination
of the safety controls with the machinery, the safety system design,
and proper installation practices are all necessary to meet the
objectives of overall safety.
