Introduction
Section 1 Introduction
1.1 Scope and purpose of the safety manual
This safety manual contains the information to design, install, verify and maintain a Safety
Instrumented Function (SIF) utilizing the Rosemount 2130 level switch.
The manual provides the necessary requirements to enable the integration of the
2130 level switch when showing compliance with the IEC 61508 or IEC 61511 functional safety
standards. It indicates all assumptions that have been made on the usage of the Level Switch. If
these assumptions cannot be met by the application, the SIL capability of the Rosemount 2130 may
be adversely affected.
Note
For product support, use the contact details on the back page.
1.2 Skill level requirement
System design, installation and commissioning, and repair and maintenance shall be carried out by
suitably qualified personnel.
1.3 Terms, abbreviations, and acronyms
Basic Safety
Freedom from unacceptable risk of harm.
BPCS
Basic Process Control System – a system which responds to input signals from the process, its
associated equipment, other programmable systems and/or an operator and generates output
signals causing the process and its associated equipment to operate in the desired manner but
which does not perform any safety instrumented functions with a claimed SIL greater than or equal
to 1.
Fail-safe State
State where switch output is in the state corresponding to an alarm condition. In this condition the
switch contacts will normally be open.
Fail Dangerous
Failure that does not respond to an input from the process (i.e. not switching to the fail-safe state).
Fail Dangerous Detected
Failure that is dangerous but is detected.
