Section 1 Caution Statements
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
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.
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.
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.
CAUTION STATEMENTS
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

CAUTION STATEMENTS
t
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.

Section 2 General Description
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).

GENERAL DESCRIPTION
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 Delay
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
Advanced Thermal Modelling
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
Undercurrent
to set the level for an undercurrent trip and parameter 4D
to set a delay on the trip.
Undercurrent
to select the response for an undercurrent trip (trip, warn or write
Troubleshooting
on page 54 for details.
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.

4.6 Control Wiring
The soft starter can be controlled in three ways:
using the buttons on the Controller via remote inputs via a serial communication link
The LCL/RMT button controls whether the MVS 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 serial communication network is always enabled in local control mode, and can be enabled or disabled in remote control mode (refer to parameter 6R). Control via the serial communication network requires an optional communication module.
The STOP button on the Controller is always enabled.
The MVS has three fixed inputs for remote control. These inputs should be controlled by contacts rated for low voltage, low current operation (gold flash or similar).

Main Contactor
The MVS must always be installed with a main contactor. Select a contactor with an AC3 rating greater than or equal to the full load current rating of the connected motor or there is an option for a circuit breaker above 7.2 kV.
The main contactor 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 MVS (refer to
Power Circuit Configuration
).
To ensure that the potentially dangerous medium voltage area is isolated from the low voltage control area, power is supplied to the main contactor coil from the control voltage terminal block (refer to
Internal Wiring
).
Bypass Contactor
The MVS must always be installed with a bypass contactor. Select a contactor with an AC1 rating greater than or equal to the full load current rating of the connected motor or there is an option for a circuit breaker above 7.2 kV.

4U, 4V – Instantaneous Overcurrent Stage 2
The MVS 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 SCR. When Stage 1 triggers, the SCRs continue to conduct current for some time and the starter performs a controlled stop. 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.

6 Inputs
The MVS has two programmable inputs, which allow remote control of the soft starter.
6A – Input A Function
710-13019-00A MVS User Manual Page 31
Options: Motor Set Select (Default) The MVS can be configured with two separate sets of motor
data. To use the secondary motor data, parameter 6A must be set to Mo tor Set Select and C53, C5 4 must be closed when a s ta rt command is given. The MVS checks which motor data to use at a start, and will use that motor data for the entire start/stop cycle.
PROGRAMMING MENU
Description: Selects the function of Input A.
6B – Input A Name
Options: Input Trip (Default) No Flow
Description: Selects a message for the Controller to display when Input A is active.
6C, 6D, 6E – Input A Trip
Parameter 6C
Input Trip (N/O) Input A can be used to trip the soft starter. When parameter
6A is set to Input Trip (N/O), a closed circuit across C53, C54 trips the soft starter. (Refer to parameters 6C, 6D, 6E)
Input Trip (N/C) When parameter 6A is set to Input Trip (N/C), an open circuit
across C53, C54 trips the soft starter. (Refer to parameters 6C, 6D, 6E)
Local/Remote Select Input A can be used to select between local and remote
control, instead of using the LCL/RMT 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 START and LCL/RMT 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 MVS stops the motor.
Emergency Stop The MVS can be commanded to emergency stop the motor,
ignoring the soft stop mode set in parameter 2H. When the circuit across C53, C54 is opened, the soft starter allows the motor to coast to stop.

Section 9 Operation
CAUTION 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.
9.1 Using the Soft Starter to Control a Motor
To soft start the motor, press the START button on the Controller or activate the Start remote input. The motor will start using the start mode selected in parameter 2A.
To stop the motor, press the STOP button on the Controller or activate the Stop remote input. The motor will stop using the stop mode selected in parameter 2H.
To reset a trip on the soft starter, press the RESET button on the Controller or activate the Reset remote input.
To emergency stop the motor, press the local STOP and RESET buttons at the same time. Alternatively, one of the programmable inputs can be configured for emergency stop (parameters 6A and 6F). The soft starter will remove power from the motor and open the main contactor, and the motor will coast to stop.

9.4 Motor Protection
Motor, System and Soft Starter Protection Mechanisms
The MVS 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 to control the situation where the protections will activate and parameter group 16 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 discrimination with the soft starter.
When using fuse and main contactors, set the breaker current parameters to coordinate with the fuse and contactor. The contactor must not open if the current is above its maximum value. The fuse must act first or the upstream breakers instantaneous trip level must be less than the contactor's fault break current level.
If using breakers only, set breaker so that the maximum instantaneous trip time is < 150 ms.
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 MVS 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).

TROUBLESHOOTING
Section 10 Troubleshooting
The MVS 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 MVS 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.
10.1 Protection Responses
When a protection condition is detected, the MVS will write this to the event log and may also trip or issue a warning. The soft starter's response to some protections may depend on the Protection Action settings (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 MVS trips you will need to identify and clear the condition that triggered the trip, then reset the soft starter before restarting. To reset a the starter, press the RESET button on the Controller or activate the Reset remote input.
If the MVS has issued a warning, the soft starter will reset itself once the cause of the warning has been resolved.
10.2 Trip Messages
This table lists soft starter's protection mechanisms and the probable cause of the trip. Some of these can be adjusted using parameter group 4 protections and cannot be set or adjusted.

Assy Power Low
Control voltage to the power interface PCB has dropped below the required level. Check that the control voltage transformer and control circuit fuses are healthy, and that voltage is present at the terminal block (terminals A1-A2 or A2-A3) within the specified range. This trip is not adjustable.
Battery/clock
A verification error has occurred on the real time clock, or the backup battery voltage is low. If the battery is low and the power is off, date/time settings will be lost. Reprogram the date and time. Related parameters: 16M
Bypass fail (bypass contactor)
The bypass contactor has welded closed or is not operating correctly. There may be a problem with the control circuit or the contactor coil. Check the condition of the bypass contactor's main poles. Check the operation of the contactor control circuitry and contactor coil. This trip is not adjustable.
NOTE You can use the Run Simulation to check the bypass contactor's operation without mains voltage connected.

There is a problem with the SCR firing or feedback system.
Check that the fibre-optic cables between the power interface PCB and the gate drive
adaptor PCBs are properly connected.
The value of the grading resistor may not be suitable for the nominal mains voltage. If you
are using a low voltage motor for testing purposes, contact your local supplier for advice.
This trip is not adjustable.
Control Volts Low
Control voltage to the Controller has dropped below the required level. Check that the control voltage transformer and control circuit fuses are healthy, and that voltage is present at terminals A11, A12 within the specified range. This trip is not adjustable.
Current imbalance
Current imbalance can be caused by problems with the motor, the environment or the installation, such as:
An imbalance in the incoming mains voltage A problem with the motor windings A light load on the motor A phase loss on input terminals L1, L2 or L3 during Run mode An SCR that has failed open circuit. A failed SCR can only be definitely diagnosed by
replacing the SCR and checking the starter's performance. If you have recently replaced or repaired a phase arm, the connector at the back of the phase arm may not be securely plugged into the connector on the body of the power assembly.
Page 54 MVS User Manual 710-13019-00A
Remove the securing bolts and slide the phase arm out, then slide it back in firmly. Ensure
the connectors on the PCBs meet properly then retighten the bolts. There may be an open circuit SCR gate lead, or damage to the SCR gate.
Check the SCR gate connections (check at the SCRs and at the firing PCB). Consult your
local supplier for details of the SCR gate testing procedure. Related parameters: 4H, 4I, 16E

The motor was unable to accelerate to full speed in the time allowed. Excess start time trip can occur in the following conditions:
parameter 1A parameter 2D parameter 2B
setting
The motor may have experienced an abnormal increase in loading or might be jammed.
Related parameters: 1A, 2A-2D, 4A, 16B The mains frequency has gone beyond the specified range.
Check for other equipment in the area that could be affecting the mains supply (particularly variable speed drives and switch mode power supplies (SMPS). If the MVS is connected to a generator set supply, the generator may be too small or could have a speed regulation problem. Related parameters: 4J, 4K, 4L, 16F
There is a problem with the SCR gate drive.
Check that the fibre-optic cables are properly connected between:
1. the power interface PCB and the gate drive adaptor PCBs and
2. the gate drive PCB and gate current firing PCBs.
Check the supply to the gate drive adaptor PCBs, gate drive PCB and gate circuit firing PCBs. There may be a fault with the gate drive adaptor PCBs, gate drive PCB or gate circuit firing
PCBs. Contact your local supplier for advice. This trip is not adjustable.
Ground current (monitored through a dedicated current transformer) has exceeded the selected level. Test the insulation of the output cables and the motor. Identify and resolve the cause of any ground fault. Related parameters: 4O, 4P, 16N
Identify and resolve the condition which caused Input A to activate. Related parameters: 6A, 6B, 6C, 6D, 6E, 16G
Identify and resolve the condition which caused Input B to activate. Related parameters: 6F, 6G, 6H, 6I, 6J, 16H
The motor has experienced a sharp rise in motor current, probably caused by a locked rotor condition (shearpin) while running. This may indicate a jammed load. A trip may also occur when a medium level fault current has been detected. This may indicate a system short circuit. Related parameters: 4E, 4F, 4U, 4V, 16D
Communication has failed between the Controller and the power interface PCB.
Check that the Controller is receiving control voltage within the specified range (terminals
A11, A12).
Check that the fibre-optic cables between the Controller and the interface PCB are firmly
connected.
Check that each fibre-optic cable is emitting light at the Rx end.
This trip is not adjustable. The MVS has tripped on an internal fault. Contact your local supplier with the fault code (X).
Related parameters: None During pre-start checks the starter has detected a phase loss as indicated.
In run state, the starter has detected that the current on the affected phase has dropped below
3.3% of the programmed motor FLC for more than 1 second, indicating that either the incoming phase or connection to the motor has been lost. Check the supply and the input and output connections at the starter and at the motor end.

During prestart checks the starter has detected a shorted power assembly or a short within the bypass contactor as indicated. This trip is not adjustable.
There is a problem with the soft starter's connection to the motor. If only one phase is affected, the error message will indicate which phase (T1, T2, T3).
Ensure the motor is connected to terminals T1, T2, T3 using in-line (three wire) connection.
The MVS does not support inside delta (six wire) connection.
Check that the fibre-optic cables between the power interface PCB and the gate drive
adaptor PCBs are firmly connected.
Check each output phase of the soft starter for power circuit continuity.
This trip will also occur when there is a phase imbalance across the soft starter’s input terminals L1, L2, L3. Related parameters: None
The motor has reached its maximum thermal capacity. Overload can be caused by:
The soft starter protection settings not matching the motor thermal capacity Excessive starts per hour Excessive throughput Damage to the motor windings
Resolve the cause of the overload and allow the motor to cool. If you think the soft starter has tripped incorrectly, check the parameter settings. Related parameters: 1A, 1B, 1C, 1D, 9B, 16A
The external resistance across the motor thermistor input (terminals B4, B5) has exceeded 2.4 kΩ.
If the starter tripped at power-up, no thermistor is present at terminals B4, B5. If you are not
using a thermistor, you must attach a link across terminals B4-B5.
If the starter tripped during operation, the temperature of the motor winding has increased.
Resolve the cause of the overheating. Related parameters: 16I
The network master has sent a trip command to the starter, or there may be a network communication problem. Check the network for causes of communication inactivity. Related parameters: 16K
There has been a voltage surge on the mains. Causes can include problems with a transformer tap regulator or off-loading of a large transformer load.
Check that the starter is configured appropriately for local conditions. Monitor the mains voltage to determine the cause of the voltage fluctuation, and resolve the

Power Factor Correction
NOTE Do not connect power factor correction capacitors to the output of MVS soft starters. If static power factor correction is employed, it must be connected to the supply side of the soft starter.
Power factor correction capacitors should be selected based on the motor data and the required final power factor.
If power factor correction capacitors are being used, select a contactor according to the required kVAr. The contactor must be connected on the supply side of the soft starter. The power factor correction capacitor contactor coil is associated with output terminals 33, 34 of the soft starter's Interface PCB.
Line Inductors
Output line inductors are required if the cable run between the soft starter and the motor is greater than 200 m. Line inductors should be installed outside the panel, between the soft starter output (terminals T1, T2, T3) and the motor. Contact your local supplier for selection details.
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.
Control Supply Transformer (PT/VT)
The MVS requires a low voltage control supply. If low voltage is not available, a transformer is required. Use a transformer with primary voltage matching the MV mains voltage, and secondary voltage to suit the MVS starter. Use a single phase 500 VA transformer with protection fuses on both the primary and secondary sides.
