CAUTION STATEMENTS

710-13019-00A MVS User Manual Page 3

This symbol is used throughout this manual to draw attention to topics of special importance to the

installation and operation of MVS Series soft starters.

Caution Statements cannot cover every potential cause of equipment damage but can highlight common causes of

damage. It is the installer's responsibility to read and understand all instructions in this manual prior to installing, operating

or maintaining the soft starter, to follow good electrical practice including applying appropriate personal protective

equipment and to seek advice before operating this equipment in a manner other than as described in this manual.

Read and understand the entire manual before installing operating, or maintaining the starter. Follow all

applicable local and national codes.

Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices.

Use only electrically insulated tools and clothing and insulated protective gear when working around electrical

equipment.

Disconnect all power and ensure that the starter is de-energised before servicing the starter.

Do not rely on visual indications such as switch position or fuse removal for determining a de-energised

condition. Always assume that a terminal is energised until it is checked with a properly rated meter to ensure

that a terminal is de-energised and grounded.

Isolate the soft starter completely from the power supply before attempting any work on the starter or motor.

Always use a properly rated voltage sensing device to confirm power is off.

Before servicing the starter, ensure that all static charge has been discharged by grounding it with an appropriate

grounding device.

Metal swarf in the cabinet can cause equipment failure.

Do not apply voltage to the control input terminals. These are active 24 VDC inputs and must be controlled

with potential free contacts.

Contacts or switches operating the control inputs must be suitable for low voltage, low current switching (ie gold

flash or similar).

Cables to the control inputs must be segregated from mains voltage and motor cabling.

Some electronic contactor coils are not suitable for direct switching with PCB mount relays. Consult the

contactor manufacturer/supplier to confirm suitability.

The examples and diagrams in this manual are included solely for illustrative purposes. The information contained in this

manual is subject to change at any time and without prior notice. In no event will responsibility or liability be accepted for

direct, indirect or consequential damages resulting from the use or application of this equipment.

WARNING - ELECTRICAL SHOCK HAZARD

MVS soft starters contain dangerous voltages when connected to mains voltage. Only a qualified electrician

should carry out the electrical installation. Improper installation of the motor or the soft starter may cause

equipment failure, serious injury or death. Follow this manual and local electrical safety codes.

SHORT CIRCUIT

MVS soft starters are not short circuit proof. After severe overload or short circuit, the operation of the soft

starter should be fully tested by an authorised service agent.

GROUNDING AND BRANCH CIRCUIT PROTECTION

It is the responsibility of the user or person installing the soft starter to provide proper grounding and branch

circuit protection according to local electrical safety codes.

ARC FLASH HAZARD

Soft starters have a potential risk of arc flash. When insulation or isolation between electrified conductors is

breached or can no longer withstand the applied voltage, a short circuit occurs through the air. This may cause

a phase-to-ground and/or a phase-to-phase fault.

AuCom soft starters have been designed to mitigate an arc fault, however it is the responsibility of the site

engineer to ensure that personnel are protected from serious injury that may result from an arc fault.

Although unlikely, arc fault can be caused by:

Contamination in the insulation caused by deterioration over time

Section 1 Caution Statements

CAUTION STATEMENTS

Page 4 MVS User Manual 710-13019-00A

Inadequate insulation system on cable terminals

Overvoltage

Incorrect protection coordination settings

Overheating of the contact area, due to incorrect tightening of connections

Introduction of foreign matter, including swarf, vermin, tools or maintenance equipment left in the starter

STORAGE

The starter must be stored in its original packaging in a clean and dry environment. The starter should be

unpacked only after the equipment room is ready for installation. Particular care should be taken to avoid

exposure of the electronics to cement and/or concrete dust.

As AuCom is continuously improving its products it reserves the right to modify or change the specification of its products at any

ime without notice. The text, diagrams, images and any other literary or artistic works appearing in this document are protected

GENERAL DESCRIPTION

710-13019-00A MVS User Manual Page 5

2.1 Overview

The MVS provides compact and robust soft start solutions for control of medium voltage motors. MVS soft starters

provide a complete range of motor and system protection features and have been designed for reliable performance in the

most demanding installation situations.

Each MVS soft starter comprises two elements:

a power assembly

a controller module

The power assembly and controller module are supplied as a pair and share the same serial number. Care should be

taken during installation to ensure the correct controller and power assembly are used together.

Each MVS is also supplied with two fibre-optic cables, to connect the controller module to the power assembly, and three

non-conduction lead assemblies, allowing the soft starter to be tested with a low-voltage motor (< 500 VAC).

2.3 Key Features

MVS soft starters offer several special functions to ensure ease of use and to provide optimal motor control in all

environments and applications.

Customisable Protection

The MVS offers comprehensive protection to ensure safe operation of the motor and soft starter. The protection

characteristics can be customised extensively to match the exact requirements of the installation.

Use parameter group 4 on page 28 to set the conditions in which each protection mechanism will activate.

Example: use parameter 4C

Undercurrent

to set the level for an undercurrent trip and parameter 4D

Undercurrent Delay

to set a delay on the trip.

Use parameter group 16 on page 39 to select the soft starter's response when a protection mechanism activates. Each

protection can be set to trip the starter, activate a warning flag, or be ignored. All protection activations are recorded in

the event log, regardless of the protection class setting.

Example: Use parameter 16C

Undercurrent

to select the response for an undercurrent trip (trip, warn or write

to log). The default response is trip.

NOTE

MVS soft starters have built-in trip points to ensure operation remains within the soft starter's capability.

These internal trips cannot be overridden. Certain faults within the MVS will also prevent the soft starter

from operating. Refer to

Troubleshooting

on page 54 for details.

Advanced Thermal Modelling

Intelligent thermal modelling allows the soft starter to predict whether the motor can successfully complete a start. The

MVS uses information from previous starts to calculate the motor's available thermal capacity, and will only permit a start

which is predicted to succeed.

This feature can be enabled or disabled using parameter 4N

Motor Temperature Check

Comprehensive Event and Trip Logging

The MVS has a 99-place event log to record information on soft starter operation. A separate trip log stores detailed

information about the last eight trips.

Informative Feedback Screens

A digital display screen allows the MVS to display important information clearly. Comprehensive metering information,

details of starter status and last start performance allow easy monitoring of the starter's performance at all times.

Dual Parameter Set

The MVS can be programmed with two separate sets of operating parameters. This allows the soft starter to control the

motor in two different starting and stopping configurations.

The secondary motor settings (parameter groups 9 and 10) are ideal for dual speed motors or conventional (squirrel-cage)

motors which may start in two different conditions (such as loaded and unloaded conveyors).

NOTE

MVS soft starters are not suitable for controlling two separate motors. The secondary parameter set

should only be used for a secondary configuration of the primary motor.

The MVS will use the secondary motor settings to control a start when instructed via a programmable input (refer to

parameters 6A and 6F

Input A or B Function

Fibre Optics

The MVS uses two-line fibre optic connections between the low voltage control module and the high voltage power

assembly for electrical isolation. This fibre optic link simplifies installation of chassis mount MVS starters into custom panels.
