2. Caution Statements

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 equipment, 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 MVE. Follow all applicable

local and national codes.

• Apply appropriate personal protective equipment (PPE) and clothing, and follow safe electrical work practices.

• Disconnect all power and ensure that the MVE is de-energised before servicing the equipment.

• 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 and ensure that a terminal is de-energised and grounded.

• Isolate the MVE completely from the power supply before attempting any work on the MVE or motor.

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

• Before servicing the MVE, 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.

• The control inputs are powered by the soft starter. Do not apply external voltage to the control input terminals.

• 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 contactor coils are not suitable for direct switching with PCB mount relays.

The MVE contains dangerous voltages when connected to mains voltage. Only a qualified electrician should carry out the electrical installation. Improper installation of the motor or the MVE may cause equipment failure, serious injury or death. Follow this manual and local electrical safety codes.

The MVE is not short circuit proof. After severe overload or short circuit, the operation of the MVE should be fully tested by an authorised service agent.

It is the responsibility of the user or person installing the MVE to provide proper grounding and branch circuit protection according to local electrical safety codes.

Medium voltage equipment has 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.

Although unlikely, arc fault can be caused by:

• Contamination in the insulation caused by deterioration over time

• 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

AuCom medium voltage equipment has 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.

NOTE NOTE

3.3 Key Features

MVE 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 MVE 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

4 Protection Settings

Use parameter 4C

Use

Use parameter 16C

MVE 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 MVE will also prevent the soft starter from operating. Refer to

on page 48 to set the conditions in which each protection mechanism will activate.

Delay

to set a delay on the trip.

16 Protection Action

Undercurrent

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

Undercurrent

on page 60 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.

Undercurrent

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

The default response is trip.

Troubleshooting

on page 66 for details.

• Advanced Thermal Modelling

Intelligent thermal modelling allows the soft starter to predict whether the motor can successfully complete a start. The MVE 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 MVE 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. Refer to download the software, visit www.aucom.com.

Starter Trip and Event Logger Software

on page 7 for details. For further information, or to

• Informative Feedback Screens

A digital display screen allows the MVE 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 MVE 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 conventional (squirrel-cage) motors which may start in two different conditions (such as loaded and unloaded conveyors).

The MVE is not suitable for controlling two separate motors. The secondary parameter set should only be used for a

The MVE will use the secondary motor settings to control a start when instructed via a programmable input (refer to parameters 6A and 6F,

secondary configuration of the primary motor.

Input A or B Function

• Fibre-Optics

The MVE uses two-line fibre-optic connections between the low voltage and high voltage zones for electrical isolation. This fibre-optic link simplifies installation of chassis mount MVE starters into custom panels.

6.12 Power Circuits

Overview

MVE soft starters are designed to operate as part of a system including other components. A bypass contactor or circuit breaker is required in all installations. MVE can also be installed with a main contactor. In this case, MVE must be installed with fuses.

Additional components may also be required to comply with soft starter panel specifications.

Main Switching Device

The MVE can be installed with a main contactor or a circuit breaker.

• Select a contactor with an AC3 rating greater than or equal to the full load current rating of the connected motor.

• Select a circuit breaker greater than or equal to the full load current rating of the connected motor.

The main switching device is associated with terminals L1, L2, L3 on the supply side of the soft starter. The coil is associated with output terminals 13, 14 of the MV-DS (refer to

To ensure that the potentially dangerous medium voltage area is isolated from the low voltage control area, power is supplied to the main switching device coil from the control voltage terminal block (refer to

Bypass Switching Device

The MVE must always be installed with a bypass contactor or circuit breaker.

• Select a contactor with an AC1 rating greater than or equal to the full load current rating of the connected motor.

• Select a circuit breaker greater than or equal to the full load current rating of the connected motor.

The bypass switching device is associated with terminals L1, L2, L3 on the supply side of the soft starter, and bypass terminals T1B, T2B, T3B on the motor side. The coil is associated with output terminals 23, 24, and the auxiliary Normally Open contact is associated with input terminals C73, C74 of the soft starter (refer to

To ensure that the potentially dangerous medium voltage area is isolated from the low voltage control area, power is supplied to the bypass switching device coil from the control voltage terminal block (refer to

Power Circuit Configuration

on page

Internal Panel Wiring

on page 27).

on page 24).

on page 27).

R Rated Protection Fuses

If the MVE is installed with a main contactor, R Rated protection fuses must be installed on the supply side of the soft starter to provide Type 1 coordination and short circuit protection for the motor branch circuit. Select the appropriate fuse based on the motor's rated full load current.

Power Factor Correction

Power factor correction capacitors must be connected to the input side of the soft starter. Connecting power factor correction capacitors to the output side will damage the soft starter

Incorrect installation

Power factor correction capacitors should be selected based on the motor data and the required final power factor. Select a contactor according to the required kVAr.

Power factor correction capacitors must be connected to the supply side of the soft starter.

Correct installation

The soft starter must control the power factor correction capacitor contactor. Use the run output (terminals 33, 34 on the power interface board).

Transient/ Overvoltage Protection

Overvoltage protection should be installed if there is a risk of high voltage transients at the installation. Contact your local supplier for details.

Line Inductors

Output line inductors may be required depending on various factors, including the soft starter model, the system operating voltage, the cable type, and the length of the cable run between the soft starter and the motor.

If required, line inductors are typically installed in a shielded caged enclosure at the soft starter end of the motor cable.

To find out if line inductors are required for your specific installation, contact your local supplier for advice. You will need to provide information about the motor output cable, including the cable length and its capacitance per km.

Power Circuit Configuration

MVE power circuit with main contactor, bypass contactor, main isolator/ earth switch, R Rated fuses and current transformers. MVE must be installed with backup/R-rated fuses.

NOTE

NOTE CAUTION

6.15 Operation mode selector switch (S1)

The MVE can soft start the motor, or can DOL start the motor with or without protection. Use the operation mode selector switch (S1) to select the start mode.

SST position (soft start)

• The customer's external control signals start and stop the motor.

• The MVE performs a normal soft start.

• All soft starter protections are active.

DOL+ position (DOL with protection)

• Relay outputs on the soft starter's power interface board control the line, bypass and PFC contactors.

• The customer's external control signals start and stop the motor.

• The line and bypass contactors start the motor DOL.

• All soft starter protections are active.

• Relay outputs on the soft starter's power interface board control the line, bypass and PFC contactors.

This mode allows the motor to be started when there is a fault with one of the soft starter phase arms. The controller and power interface board must be in healthy working state.

DOL position (DOL without protection)

• The customer's external control signals start and stop the motor.

• The line and bypass contactors start the motor DOL.

• All soft starter protections are bypassed.

• The line and bypass contactors are controlled by the start and stop control signals.

• The PFC contactor (if used) must be controlled by a separate manual switch.

This mode allows emergency operation of the motor when there is a major failure of any soft starter component. Back-up fuses provide short circuit protection. Additional protections such as motor protection or RTD overtemperature may be available if separate protection equipment is installed.

6.16 Phase arm power supply switching

The 24 VDC power supply to each phase arm must be switched via a control relay operated from output 43, 44 on the power interface board. Refer to

The control relay (KPA) must have a contact switching rating > 9A @ 24 VDC.

Internal Panel Wiring

7.12 Operation

Adjustment Lock

(parameter 15B) is set to Read

We recommend testing the soft starter's setup on a low voltage motor before beginning operation on a medium voltage motor. This allows the operator to test that the soft starter is correctly connected to the auxiliary equipment.

Start, Stop and Reset Commands

The soft starter can be controlled in three ways:

• using the buttons on the controller

• via remote inputs

• via a serial communication link

The

button controls whether the MVE will respond to local control (via the controller) or remote control (via the remote

inputs).

The Local LED on the controller is on when the soft starter is in local control mode and off when the soft starter is in remote control mode.

Control via the fieldbus communication network is always enabled in local control mode, and can be enabled or disabled in remote control mode (parameter 6R

Timed Voltage Ramp

Timed voltage ramp (TVR) soft starting ramps the application of voltage to the motor over a defined time period. The voltage ramp reduces the initial starting torque and slows the motor's rate of acceleration.

TVR starting can be useful for applications where multiple motors of different sizes are connected in parallel, and/or the loads are not mechanically linked.

TVR soft starting is not suitable for high inertia loads (such as fans), which require a high level of voltage to accelerate the load.

For multiple motors of the same sizes, and/or mechanically coupled loads, use constant current starting.

For a timed voltage ramp start, the following are typical values and can be adjusted to suit your specific application:

1. Add the FLC value of all the connected motors. Use this combined value to set parameter 1A

Not ready

Control power is on. The starter may be in Restart Delay mode or waiting for the motor to cool down before allowing a start.

Ready The starter is initialised and waiting for a start command.

Pre-start checks

A start command has been received (a). The main contactor closes (b) and the starter performs a series of internal and external checks.

Starting The starter ramps the SCRs up to full conduction and closes the bypass contactor (c).

Running The motor is running normally.

Stopping

A stop command has been received (d). The starter opens the bypass contactor (e), ramps the SCRs down to no conduction, then opens the main contactor (f).

• Trip States

The starter's response to a trip depends on the starter's state when the trip occurs.

 Trip while starting (bypass contactor not yet closed)

 Trip while running (bypass contactor closed)

Not ready Perform system checks.

Motor Protection

• Motor, System and Soft Starter Protection Mechanisms

The MVE incorporates extensive protection features to ensure safe operation of the motor, system and soft starter. Most protection features can be customised to suit the installation. Use parameter group 4 Protection Settings to control the situation where the protections will activate and parameter group 16 Protection Action to select the soft starter's response. The default response is to trip the soft starter.

 Protection Coordination

Check protection settings on the supply side of the starter to ensure correct coordination with the parameters of the soft starter.

When using fuse and main contactors, set the upstream circuit breaker protection parameters according to the ratings for fuse and contactor. The contactor must not open if the current is above its maximum breaking current value. The fuse must act first or the upstream breakers instantaneous trip level must be less than the contactor's maximum breaking current level.

If using circuit breakers only, set the soft starter's maximum instantaneous trip time < 150 ms. Always use a suitable external protection relay with a circuit breaker to ensure instantaneous overcurrent trip functionality.

Voltage must not be continuously maintained on the phase arms while the motor is off. Short circuit protective equipment must be installed in all cases.

 Motor Overload Protection

The MVE offers thermal model motor overload protection which monitors the performance of the motor and calculates its temperature in all states. This protection is based on the motor information programmed in parameter groups 1 and 9, and the thermal model adjusts itself according to the motor's recent operating history (including temperature rise from previous operation).

4 Protection Settings

These parameters determine when the soft starter's protection mechanisms will activate. The activation point for each protection mechanism can be set to suit the installation.

The soft starter responds to protection events by tripping, warning, or writing the event to the event log. The response is determined by the Protection Action settings. The default response is a trip.

The protection settings are vital for safe operation of the soft starter and motor. Defeating the protection may

Excess start time is the maximum time the MVE will attempt to start the motor. If the motor does not transition to Run mode within the programmed limit, the starter will trip. Set for a period slightly longer than required for a normal healthy start. A setting of 0 disables excess start time protection.

The MVE can be configured to trip if the average current of all three phases exceeds a specified level while the motor is running.

The MVE has two instantaneous trip functions, stage 1 and 2. These protection functions are configured to be complementary.

Stage 1 must be configured to protect the motor against a locked rotor (shearpin) situation during run mode. Stage 1 should trigger at lower current/higher time values than Stage 2.

Stage 2 must be configured to protect the main switching device. When Stage 2 triggers, the starter opens the main switching device.

If the main switching element is a contactor (protected by a fuse), then this function must be coordinated with the fuse to ensure that the contactor does NOT open until the fuse ruptures.

If the main switching element is a breaker, then the delay must be minimised to provide the best possible protection to the SCR.

button on the controller. When the input is open, the starter is in local mode and can be controlled via the controller. When the input is closed, the starter is in remote mode. The

buttons are disabled, and the soft starter will ignore any Local/Remote select command from the serial communications network. To use Input A to select between local and remote control, parameter 6Q must be set to 'LCL/RMT Anytime' or 'LCL/RMT When Off'.

Emergency Run

In emergency run the soft starter continues to run until stopped, ignoring all trips and warnings (refer to parameter 15C for details). Closing the circuit across C53, C54 activates emergency run. Opening the circuit ends emergency run and the MVE stops the motor.

Starter Disable

The MVE can be disabled via the control inputs. An open circuit across C53, C54 will disable the starter. The MVE will not respond to start commands. If running, the soft starter will allow the motor to coast to stop, ignoring the soft stop mode set in parameter 2H.

Output

The MVE can be connected to a low voltage motor (≤ 500 VAC) for testing. To conduct the low voltage test you need to use an LV motor test resistor assembly (part number 995-03946-00). This allows the user to thoroughly test the soft starter and its associated power and control circuits. The low voltage test mode provides a means of testing the soft starter's configuration without requiring a full medium voltage test facility.

During the low voltage test, the soft starter's control input, relay output and protection settings can be tested. Low voltage mode is not suitable for testing soft starting or soft stopping performance.

The FLC for the low voltage motor must be ≥ 5 A (see parameter 1A

9. Troubleshooting

The MVE provides extensive information to help the operator diagnose and remedy any operating difficulties.

In addition to the motor and load protection features already described, the MVE reports in detail on the starter's own state. Any internal failure will cause the soft starter to trip, and full details will be recorded in the Trip Log and Event Log.

9.1 Protection Responses

When a protection condition is detected, the MVE will write this to the event log and may also trip or issue a warning. The soft starter's response depends on the Protection Action setting (parameter group 16).

Some protection responses cannot be adjusted by the user. These trips are usually caused by external events (such as phase loss) or by a fault within the soft starter. These trips do not have associated parameters and cannot be set to Warn or Log.

If the MVE trips you will need to identify and clear the condition that triggered the trip, then reset the soft starter before restarting. To reset the starter, press the

1. Configure the MVE as follows:

Parameter settings:

• Parameter 7A

Relay A Function

• Select 'Changeover Contactor'

• Parameter 7B

Relay A On Delay

• Set this to the maximum time (5m:00s).

• Parameter 12A

Motor Data-1 Ramp

• Select 'Dual Ramp' (for slip-ring induction motor control)

• Parameter 12C

Changeover Time

• Default setting is 150 milliseconds. Set this to a value just greater than the changeover contactor (K3) pole

closing time.

• Parameter 12D

2. Start the motor under normal load conditions and record the time it takes to reach a constant speed with external rotor

• Default setting is 50%. Set this parameter to a value which is high enough to cause the motor to instantly

accelerate once the rotor resistance (R1) has been bridged out and low enough to avoid a motor current pulse.

Slip Ring Retard

resistance (R1) in the circuit. Stop the motor soon after a constant speed has been reached. Change parameter 7B to the recorded time value.

3. Start the motor under normal load conditions and monitor the motor speed behaviour and motor current when the

changeover contactor (K3) switches in to short-out the rotor resistance (R1) If the motor does not start to accelerate immediately after changeover, increase the setting of parameter 12D. If there is a pulse in motor current immediately after changeover, reduce the setting of parameter 12D.
