Abbreviations; Exclusion Of Liability; Quick Reference Guide For Implementing A Safety System - ABB ACS880 User Manual

Abbreviations

Abbreviations used in this manual are listed below.
Abbreviation Description
Cat. Category. Classification of the safety-related parts of a control system
in respect of their resistance to faults and their subsequent behavior
in the fault condition, and which is achieved by the structural
arrangement of the parts, fault detection and/or by their reliability.
The categories are: B, 1, 2, 3 and 4.
HFT Hardware fault tolerance
IGBT Insulated gate bipolar transistor
PL Performance level (levels are: a, b, c, d and e). Corresponds to SIL.
POUS Prevention of unexpected start-up
SIL Safety integrity level
STO Safe torque off

Exclusion of liability

ABB is not responsible for the implementation, verification and validation of the overall
safety system. It is the responsibility of the system integrator (or other party) who is
responsible for the overall system and system safety.
The system integrator (or other responsible party) must make sure that the entire
implementation complies with all relevant standards, directives and local electrical code,
and that the system is tested, verified and validated correctly.

Quick reference guide for implementing a safety system

Task
Select the appropriate functional safety standard for the implementation: EN ISO 13849-1,
EN/IEC 62061, IEC 61511 or other.
If you select EN/IEC 62061 or IEC 61511, make a safety plan. See EN/IEC 62061 or IEC 61511.
Assess safety: analyze and evaluate risks (estimate SIL/PL) and define risk reduction strategies.
Define the safety requirements.
Design the safety system. The part of the design made by ABB is described in chapter
description and instructions
Verify the achieved SIL/PL with, for example, FSDT-01 Functional safety design tool or similar. See
Functional safety design tool user's manual (3AXD10000102417 [English]).
Connect the wiring. See section
Set the parameters. See section
Validate that the implemented system meets the safety requirements:
• Do the acceptance test. See section
Write the necessary documentation.
