Exclusion Of Liability; Terms And Abbreviations - ABB ACS880 Series User Manual

14 Introduction to the manual

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 the instructions in this manual, all relevant standards, directives
and local electrical code, and that the system is tested, verified and validated correctly.

Description
Directives 2014/34/EU and 1999/92/EC are commonly referred to as the ATEX direct-
ives (from "Atmosphères Explosibles")
Type of control unit
An IEC term used in the context of explosive atmospheres (IEC 60079)
Type of protection, flameproof enclosures (EN/IEC 60079-1)
Types of protection, increased safety (EN/IEC 60079-7)

Safety integrity level (1...3) (IEC 61508)
Safe stop 1 (IEC/EN 61800-5-2)
Safe stop emergency
Safe torque off (IEC/EN 61800-5-2)
There are three categories of stop functions:
• stop category 0: an uncontrolled stop where power to the machine actuators is re-
moved immediately (STO)
• stop category 1: a controlled stop where the machine actuators have power for
stopping, after which the power is removed (SS1)
• stop category 2: a controlled stop where the machine actuators continue to have
power SS2).
Proof test interval. Defines the probabilistic failure rate (PFH or PFD
function or subsystem. Performing a proof test at a maximum interval of T
to keep the SIL capability valid. The same interval must be followed to keep the PL
capability (EN ISO 13849) valid. Note that any T
as a guarantee or warranty.
Type of control unit
Potentially explosive atmosphere. Hazardous areas are divided into zones, based on
the frequency and duration of the occurrence of an explosive atmosphere. (EN/IEC
60079)
