User’s manual Emergency stop, stop category 0 (option +Q951) for ACS880-07/17/37 drives Table of contents 2017 ABB Oy. All Rights Reserved. 3AUA0000119895 Rev F EFFECTIVE: 2018-01-25...
This chapter describes the manual in short and gives some general information for the reader. The chapter also contains a quick reference for implementing a safety system. Applicability The manual applies to ACS880-07/17/37 drives which have the option: Emergency stop, stop category 0 with main contactor/breaker, with safety relays (option +Q951). Safety instructions Only a qualified electrician who has appropriate knowledge on functional/machine/process safety is allowed to install, start up and maintain the safety circuit.
8 Introduction to the manual Target audience The manual is intended for people who install, start up, use and service the safety option of the drive. Read the manual before working on the drive. You are expected to know the fundamentals of electricity, wiring, electrical components, electrical schematic symbols, and functional safety.
EN/IEC 62061 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.
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 Option description and instructions on page 11.
Option description and instructions 11 Option description and instructions Contents this chapter This chapter describes the +Q951 emergency stop option and instructs how to wire, start up, test, validate, use and maintain it. The safety data is also given. Overview Option +Q951 corresponds to an uncontrolled stop in accordance with stop category 0 (EN/IEC 60204-1).

Option description and instructions 19 Action Push the emergency stop reset button [S62]. Ensure that the indication lamp [P62] switches off. Switch off the drive start signal. Power up the drive (see the hardware and firmware manuals). Restart the drive and motor and check that they operate normally. Repeat the test from each operating location (every emergency stop button and reset button).
20 Option description and instructions Use of the safety function Activating 1. Push the emergency stop button [S61]. The emergency stop activates and the button locks in “ON” (open) position. Resetting 1. Turn the emergency stop button [S61] until it releases. 2.
18. If you change any wiring or component after the start up, or restore parameters to their default values: • Use only ABB approved spare parts. • Register the change to the change log for the safety circuit. •...
22 Option description and instructions Intentional misuse The safety circuit is not designed to protect a machine against intentional misuse. Decommissioning When you decommission an emergency stop circuit or a drive, make sure that the safety of the machine is maintained until the decommissioning is complete.
