Safety instructions

Contents of this chapter

This chapter contains the safety instructions which you must obey when you install, operate

and do maintenance on the safety functions of a drive.

Use of warnings and notes

Warnings tell you about conditions which can cause injury or death, or damage to the

equipment. They also tell you how to prevent the danger. Notes draw attention to a particular

condition or fact, or give information on a subject.

The manual uses these warning symbols:

WARNING!

Electricity warning tells about hazards from electricity which can cause injury or

death, or damage to the equipment.

WARNING!

General warning tells about conditions, other than those caused by electricity,

which can cause injury or death, or damage to the equipment.

WARNING!

Electrostatic sensitive devices warning tells you about the risk of electrostatic

discharge which can cause damage to the equipment.

Instructions for functional safety circuits

This manual does not repeat the complete safety instructions of the drive but only includes

the instructions related to the scope of this manual.

Safety instructions 7

Only a qualified electrician who has appropriate knowledge on functional, machine, and

process safety is allowed to install, start up and maintain the safety circuit. All user-made

changes are on the user's responsibility.

WARNING! Always test the operation of the safety circuit according to its

acceptance test procedure at the start-up and after any changes to the safety

circuit.

WARNING!

Obey the safety instructions of the drive. If you ignore them, injury or death, or

damage to the equipment can occur.

If you are not a qualified electrician, do not do installation or maintenance work.

Electrical safety precautions

These electrical safety precautions are for all personnel who do work on the drive, motor

cable or motor.

WARNING!

Obey these instructions. If you ignore them, injury or death, or damage to the

equipment can occur.

If you are not a qualified electrician, do not do installation or maintenance work.

Go through these steps before you begin any installation or maintenance work.

1. Clearly identify the work location and equipment.

2. Disconnect all possible voltage sources. Lock out and tag out.

• Open the main disconnecting device of the drive.

• If you have a permanent magnet motor connected to the drive, disconnect the motor

from the drive with a safety switch or by other means.

• Make sure that re-connection is not possible. Lock out and tag out.

• Disconnect any dangerous external voltages from the control circuits.

• After you disconnect power from the drive, always wait 5 minutes to let the

intermediate circuit capacitors discharge before you continue.

3. Protect any other energized parts in the work location against contact.

4. Take special precautions when close to bare conductors.

5. Measure that the installation is de-energized.

• Use a multimeter with an impedance greater than 1 Mohm.

• Make sure that the voltage between the drive input power terminals (L1, L2, L3)

and the grounding (PE) busbar is close to 0 V.

• If you have a permanent magnet motor connected to the drive, make sure that the

voltage between the drive output terminals (T1/U, T2/V, T3/W) and the grounding

(PE) busbar is close to 0 V.

6. Ask the person in control of the electrical installation work for a permit to work.

Introduction to the manual

Contents of this chapter

This chapter describes the manual in short and gives some general information for the

reader. This chapter also contains a quick reference guide for implementing a safety system.

Applicability

The manual applies to ACS880-07/17/17LC/37/37LC drives which have the option:

Emergency stop, stop category 1 with main contactor/breaker, with safety relays (option

+Q952).

For the option +Q952, ABB installs the FIO-01 digital I/O extension module (option +L501)

to the drive.

Target audience

The manual is intended for people who install, start up, use and service the safety function.

Read the manual before working on the unit. You are expected to know the fundamentals

of electricity, wiring, electrical components, electrical schematic symbols, and functional

safety.

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.

Introduction to the manual 9

Quick reference guide for taking a safety function into use

Task

Connect the user-defined wiring (if any). See the wiring instructions in this manual and the circuit dia-

grams delivered with the drive.

Check and/or set the safety function related parameters (as listed in this manual).

Do the acceptance test to ensure that the implemented system meets the safety requirements. Instruc-

tions for the acceptance test can be found in this manual.

Document the acceptance test procedure. Guidelines for the acceptance test report can be found in

this manual.

12 Introduction to the manual

Option description

Contents of this chapter

This chapter describes the +Q952 emergency stop option and its settings.

Overview

The option +Q952 corresponds to a controlled stop in accordance with stop category 1

(EN/IEC 60204-1). After the user has given the emergency stop command, the drive first

decelerates the motor(s) to zero speed according to a preset ramp time. Then, the drive

trips the main contactor/breaker which cuts off the input power of the drive.

For the option +Q952, ABB installs the FIO-01 digital I/O extension module (option +L501)

to the drive control board (Slot 1).

Note: Drives with the Prevention of unexpected start-up (POUS) option (+Q957): If the user

activates the POUS function during the emergency stop deceleration ramp, it overrides the

emergency stop function. This activates the Safe torque off (STO) function of the drive

immediately and the motor coasts to a stop. For more information on the POUS safety

function, see Prevention of unexpected start-up (option +Q957) for

ACS880-07/17/17LC/37/37LC drives (3AUA0000119910 [English]).

The design principles of the option +Q952 comply with EN ISO13850.

For a list of related standards and European directives, see section Related standards and

directives.

Operation principle

The figures show a simplified operation principle. Implementation of main contactor/breaker

and charging circuit can vary depending on the product. For a more detailed description,

see the circuit diagrams delivered with the drive.

OperationStep

Initial status: The drive is in operation and the motor is running.

The user activates emergency stop with the emergency stop button [S61].1

14 Option description

OperationStep

The emergency stop safety relay [A61] switches off the digital input on the digital I/O extension

module [A412.X] of the drive. This gives the emergency stop command.

The emergency stop safety relay [A61] switches off the power for the timer relay [K61].

The break delay counter of the emergency stop safety relay [A61] starts (user-adjustable delay).

The break delay counter of the timer relay [K61] starts (non-user-adjustable delay).

The drive acknowledges the reception of the emergency stop command by energizing the relay output

(RO1) of the digital I/O extension module [A412.X].

The relay output of the extension module [A412.X] re-energizes the timer relay [K61] resetting its

break delay counter. The relay keeps its delayed break contact closed.

Note: If the drive fails to acknowledge the reception of the emergency stop command in 2 seconds,

the main contactor opens and the system is tripped.

The drive decelerates the motor to zero speed in emergency stop deceleration time (parameter setting).4

The break delay counter of the emergency stop safety relay [A61] trips and the delay contact switches

off the power for the extension safety relay [A62].

5 The extension safety relay [A62] switches off the power for the auxiliary safety relay [K21.1] and

auxiliary relay [K63].

The auxiliary safety relay [K21.1] switches off the main contactor/breaker [Qx].

The contact of the auxiliary relay [K63] energizes the emergency stop reset button indicator light

[S62].

Normal operation resumes after the user:

• releases the emergency stop button [S61] to normal (up) position

• resets the emergency stop circuit with the emergency stop reset button [S62] (the user must push

the button for 0.1 - 3 seconds)

• resets the drive (if the drive tripped on a fault).
