CAUTION STATEMENTS
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 EMX3 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.
NOTE
The EMX3 soft starter is not user serviceable. The unit should only be serviced by authorised service personnel. Unauthorised tampering with the unit will void the product warranty.
1.1 Electrical Shock Risk
The voltages present in the following locations can cause severe electric shock and may be lethal:
AC supply cables and connections
Output cables and connections
Many internal parts of the starter, and external option units
The AC supply must be disconnected from the starter using an approved isolation device before any cover is removed from the starter or before any servicing work is performed.
WARNING - ELECTRICAL SHOCK HAZARD
Models EMX3-0255B~EMX3-1000B, EMX3-0360C~EMX3-1600C: The bus bar and heatsink are live while the unit is operating (starting, running or stopping). If the starter is installed without a main contactor, the bus bar and heatsink are live whenever mains voltage is connected (including when the starter is ready or tripped).
SHORT CIRCUIT
EMX3 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.
FOR YOUR SAFETY
The STOP function of the soft starter does not isolate dangerous voltages from the output of the starter.
The soft starter must be disconnected by an approved electrical isolation device before accessing electrical connections.
Soft starter protection features apply to motor protection only. It is the user’s responsibility to ensure safety of personnel operating machinery.
In some installations, accidental starts may pose an increased risk to safety of personnel or damage to the machines being driven. In such cases, it is recommended that the power supply to the soft starter is fitted with an isolating switch and a circuit-breaking device (eg power contactor) controllable through an external safety system (eg emergency stop, fault detector).
The soft starter has built-in protections which can trip the starter in the event of faults and thus stop the motor. Voltage fluctuations, power cuts and motor jams may also cause the motor to trip.
There is a possibility of the motor restarting after the causes of shutdown are rectified, which may be dangerous for certain machines or installations. In such cases, it is essential that appropriate arrangements are made against restarting after unscheduled stops of the motor.
The soft starter is a component designed for integration within an electrical system; it is therefore the responsibility of the system designer/user to ensure the system is safe and designed to comply with relevant local safety standards.

C Reset
CAUTION
Do not apply voltage to the control input terminals. These are active 24 VDC inputs and must be controlled with potential free contacts.
Cables to the control inputs must be segregated from mains voltage and motor cabling.
The reset input can be normally open or normally closed. Use parameter 6M to select the configuration.
3.4 Relay Outputs
The EMX3 provides four relay outputs, one fixed and three programmable.
The Run output closes when the soft start is complete (when the starting current falls below 120% of the programmed motor full load current) and remains closed until the beginning of a stop (either soft stop or coast to stop).
Operation of the programmable outputs is determined by the settings of parameters 7A~7I.
If assigned to Main Contactor, the output activates as soon as the soft starter receives a start command and remains active while the soft starter is controlling the motor (until the motor starts a coast to stop, or until the end of a soft stop).
If assigned to a trip function, the output activates when a trip occurs.
If assigned to a flag, the output activates when the specified flag is active (parameters 7M~7O).
CAUTION
Some electronic contactor coils are not suitable for direct switching with PCB mount relays. Consult the contactor manufacturer/supplier to confirm suitability.
Three additional outputs are available on the input/output expansion card.
3.5 Motor Thermistors
Motor thermistors can be connected directly to the EMX3. The soft starter will trip when the resistance of the thermistor circuit exceeds approximately 3.6 k or falls below 20 .
No motor thermistors

NOTE
If no motor thermistors are connected to the EMX3 thermistor input terminals B4, B5 must be open. If B4,
B5 are shorted, the EMX3 will trip.
The thermistor circuit should be run in screened cable and must be electrically isolated from earth and all other power and control circuits.

Section 4 Power Circuits
POWER CIRCUITS
4.1 Motor Connection
EMX3 soft starters can be connected to the motor in-line or inside delta (also called three-wire and six-wire connection). When connecting in inside delta, enter the motor full load current (FLC) for parameter 1A. The EMX3 will automatically detect whether the motor is connected in-line or inside delta and will calculate the correct inside delta current level.
NOTE
For personnel safety, the power terminals on models up to EMX3-0105B are protected by snap-off tabs.
When using large cables, it may be necessary to break off these tabs.
Models which are internally bypassed do not require an external bypass contactor.

4.2 Bypass Contactor
Some EMX3 soft starters are internally bypassed and do not require an external bypass contactor.
Non-bypassed soft starters may be installed with an external bypass contactor. Select a contactor with an AC1 rating greater than or equal to the full load current rating of the connected motor.
Internally bypassed models:
EMX3-0023B, EMX3-0043B, EMX3-0050B, EMX3-0053B, EMX3-0076B, EMX3-0097B, EMX3-0100B, EMX3-0105B,

EMX3-0580B, EMX3-0700B, EMX3-0820B, EMX3-0920B, EMX3-1000B
Non-bypassed models:
EMX3-0255C, EMX3-0360C, EMX3-0380C, EMX3-0430C, EMX3-0620C, EMX3-0650C, EMX3-0790C,
EMX3-0930C, EMX3-1200C, EMX3-1410C, EMX3-1600C
4.3 Main Contactor
A main contactor must be installed if the EMX3 is connected to the motor in inside delta format and is optional for in-line connection. Select a contactor with an AC3 rating greater than or equal to the full load current rating of the connected motor.
4.4 Circuit Breaker
A shunt trip circuit breaker may be used instead of a main contactor to isolate the motor circuit in the event of a soft starter trip. The shunt trip mechanism must be powered from the supply side of the circuit breaker or from a separate control supply.
4.5 Power Factor Correction
If power factor correction is used, a dedicated contactor should be used to switch in the capacitors.
CAUTION
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.
4.6 Power supply fuses
Semiconductor fuses can be used for Type 2 coordination (according to IEC 60947-4-2 standard) and to reduce the risk of damage to SCRs from transient overload currents.
HRC fuses (such as Ferraz AJT fuses) can be used for Type 1 coordination according to IEC 60947-4-2 standard.
CAUTION
Adaptive Control controls the motor's speed profile, within the programmed time limit. This may result in a higher level of current than traditional control methods.
710-04840-00J EMX3 User Manual Page 15
POWER CIRCUITS
For applications using Adaptive Control to soft stop the motor with stop times greater than 30 seconds, motor branch protection should be selected as follows:
standard HRC line fuses: minimum 150% motor full load current
motor rated line fuses: minimum rating 100/150% motor full load current
motor control circuit breaker minimum long time setting: 150% motor full load current,
motor control circuit breaker minimum short time setting: 400% motor full load current for 30 seconds
NOTE
Fuse selection is based on a 400% FLC start for 20 seconds in conjunction with standard published starts per hour, duty cycle, 40°C ambient temperature and up to 1000 m altitude. For installations operating outside these conditions, consult your local supplier.
These fuse tables contain recommendations only. Always consult your local supplier to confirm the selection for your particular application.

OPERATION
Section 7 Operation
7.1 Start, Stop and Reset Commands
The soft starter can be controlled in three ways:
using the buttons on the keypad
via remote inputs
via a serial communication link
The LCL/RMT button controls whether the EMX3 will respond to local control (via the keypad) or remote control (via the remote inputs).
The Local LED on the keypad is on when the soft starter is in local control mode and off when the soft starter is in remote control mode.
The Remote LED on the EMX3 is on when the soft starter is in Remote mode and off when in Local mode.
The Remote LED is located on the main body of the starter (behind the keypad) and is only visible if the keypad is remotely mounted.
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 interface.
The STOP button on the keypad is always enabled.
Using the Soft Starter to Control a Motor
To soft start the motor, press the START button on the keypad 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 keypad 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 keypad or activate the Reset remote input.
To emergency stop the motor, press the local STOP and RESET buttons at the same time. The soft starter will remove power from the motor and open the main contactor, and the motor will coast to stop. Emergency stop can also be controlled via a programmable input.
NOTE
Adaptive Control, Jog, Brake and PowerThrough functions are not supported with inside delta (six-wire) operation. Refer to
Inside Delta Operation on page 36.
Auto-Start/Stop
The EMX3 can also be configured to auto-start or auto-stop. Auto-start/stop operation is only available in Remote mode, and must be configured using parameters 3A~3D. In Local mode, the starter will ignore any auto-start/stop setting.
7.2 Soft Start Methods
Soft starters offer a variety of methods to control motor starting. Each soft start method uses a different primary control parameter.

Page 30 EMX3 User Manual 710-04840-00J
OPERATION
Constant Current
Constant current is the traditional form of soft starting, which raises the current from zero to a specified level and keeps the current stable at that level until the motor has accelerated.
Constant current starting is ideal for applications where the start current must be kept below a particular level.

Current Ramp
Current ramp soft starting raises the current from a specified starting level (1) to a maximum limit (3), over an extended period of time (2).
Current ramp starting can be useful for applications where:
the load can vary between starts (for example a conveyor which may start loaded or unloaded). Set the initial current (parameter 2C) to a level that will start the motor with a light load, and the current limit (parameter
2D) to a level that will start the motor with a heavy load.
the load breaks away easily, but starting time needs to be extended (for example a centrifugal pump where pipeline pressure needs to build up slowly).
the electricity supply is limited (for example a generator set), and a slower application of load will allow greater time for the supply to respond.

Adaptive Control for Starting
Adaptive Control is a new intelligent motor control technique. In an adaptive control soft start, the EMX3 adjusts the current in order to start the motor within a specified time and using a selected acceleration profile.
CAUTION
Adaptive Control cannot start the motor faster than a direct on-line (DOL) start. If the start ramp time
(parameter 2B) is shorter than the motor's DOL start time, starting current may reach DOL levels.
Every application has a particular starting profile, based on characteristics of the load and the motor. Adaptive Control offers three different starting profiles, to suit the requirements of different applications. Selecting a profile that matches the inherent profile of the application can help smooth out acceleration across the full start time. Selecting a dramatically different Adaptive Control profile can somewhat neutralise the inherent profile.
The EMX3 monitors the motor's performance during each start, to improve control for future soft starts.
710-04840-00J EMX3 User Manual Page 31
OPERATION
Adaptive Control
To use Adaptive Control to control starting performance:
1.
Select Adaptive Control from the Start Mode menu (parameter 2A)
2.
Set the desired Start Ramp Time (parameter 2B)
3.
Select the desired Adaptive Start Profile (parameter 2E)
4.
Set a start Current Limit (parameter 2D) sufficiently high to allow a successful start. The first start will be a
Constant Current start. This allows the EMX3 to learn the characteristics of the connected motor. This motor data is used by the EMX3 during subsequent Adaptive Control starts.

Time
NOTE
Adaptive Control will control the load according to the programmed profile. Start current will vary according to the selected acceleration profile and the programmed start time.
If replacing a motor connected to an EMX3 programmed for Adaptive Control starting or stopping, or if the starter has been tested on a different motor prior to actual installation, the starter will need to learn the characteristics of the new motor. The EMX3 will automatically re-learn the motor's characteristics if parameter 1A Motor Full Load Current or parameter 2K Adaptive Control Gain is changed.
How to Select the Adaptive Control Start Profile
The best profile will depend on the exact details of each application.
Some loads, such as submersible pumps, should not be run at slow speeds. An early acceleration profile will raise the speed quickly, then control acceleration through the rest of the start.
CAUTION
Adaptive Control controls the motor's speed profile, within the programmed time limit. This may result in a higher level of current than traditional control methods.
Fine-tuning Adaptive Control
If the motor does not start or stop smoothly, adjust the adaptive control gain (parameter 2K). The gain setting determines how much the EMX3 will adjust future adaptive control starts and stops, based on information from the previous start. The gain setting affects both starting and stopping performance.
If the motor accelerates or decelerates too quickly at the end of a start or stop, increase the gain setting by
5%~10%.
If the motor speed fluctuates during starting or stopping, decrease the gain setting slightly.
NOTE
Changing the gain setting resets the starter's adaptive control learning. The first start after changing the gain will use constant current.
Kickstart
Kickstart provides a short boost of extra torque at the beginning of a start, and can be used in conjunction with current ramp or constant current starting.
Kickstart can be useful to help start loads that require high breakaway torque but then accelerate easily (for example flywheel loads such as presses).

Soft starters offer a variety of methods for the control of motor stopping.
OPERATION
Stop Method
Coast To Stop
TVR Soft Stop
Adaptive Control
Performance Result
Natural load run down
Extended run down time
Extended run down time according to selected deceleration profile
Brake Reduced run down time
Soft starters are often used in pumping applications to eliminate the damaging effects of fluid hammer. Adaptive
Control should be the preferred stop method for these applications.
Coast to Stop
Coast to stop lets the motor slow at its natural rate, with no control from the soft starter. The time required to stop will depend on the type of load.
TVR Soft Stop
Timed voltage ramp reduces the voltage to the motor gradually over a defined time. The load may continue to run after the stop ramp is complete.
Timed voltage ramp stopping can be useful for applications where the stop time needs to be extended, or to avoid transients on generator set supplies.

Adaptive Control for Stopping
In an adaptive control soft stop, the EMX3 controls the current in order to stop the motor within a specified time and using a selected deceleration profile. Adaptive Control can be useful in extending the stopping time of low inertia loads.
710-04840-00J EMX3 User Manual Page 33
OPERATION
NOTE
Adaptive control does not actively slow the motor down and will not stop the motor faster than a coast to stop. To shorten the stopping time of high inertia loads, use brake.
Every application has a particular stopping profile, based on characteristics of the load and the motor. Adaptive
Control offers three different stopping profiles. Choose the adaptive control profile that best matches your application requirements.

To use Adaptive Control to control stopping performance:
1.

Time
3
2. Constant deceleration
3. Late deceleration
4. Stop time (parameter 2I)
NOTE
Pump stopping: The hydraulic characteristics of pump systems vary considerably. This variation means the ideal deceleration profile and stop time will vary from application to application. The table provides guidelines on selecting between Adaptive Control deceleration profiles, but we recommend testing the three profiles to identify the best profile for the application.
Adaptive Stop Profile
Late Deceleration
Constant Deceleration
Early Deceleration
Application
High head systems where even a small decrease in motor/pump speed results in a rapid transition between forward flow and reverse flow.
Low to medium head, high flow applications where the fluid has high momentum.
Open pump systems where fluid must drain back through the pump without driving the pump in reverse.
The first Adaptive Control stop will be a normal soft stop. This allows the EMX3 to learn the characteristics of the connected motor. This motor data is used by the EMX3 during subsequent Adaptive Control stops.
NOTE
Adaptive Control will control the load according to the programmed profile. Stopping current will vary according to the selected deceleration profile and stop time.
If replacing a motor connected to an EMX3 programmed for Adaptive Control starting or stopping, or if the starter has been tested on a different motor prior to actual installation, the starter will need to learn the characteristics of the new motor. The EMX3 will automatically re-learn the motor's characteristics if parameter 1A Motor Full Load Current or parameter 2K Adaptive Control Gain is changed.
How to Select the Adaptive Control Stop Profile
The best profile will depend on the exact details of each application.
CAUTION
Adaptive Control controls the motor's speed profile, within the programmed time limit. This may result in a higher level of current than traditional control methods.
Page 34 EMX3 User Manual 710-04840-00J
OPERATION
Brake
Brake reduces the time the motor requires to stop.
During braking an increased noise level from the motor may be audible. This is a normal part of motor braking.
CAUTION
If the brake torque is set too high, the motor will stop before the end of the brake time and the motor will suffer unnecessary heating which could result in damage. Careful configuration is required to ensure safe operation of the starter and motor.
A high brake torque setting can result in peak currents up to motor DOL being drawn while the motor is stopping.
Ensure protection fuses installed in the motor branch circuit are selected appropriately.
CAUTION
Brake operation causes the motor to heat faster than the rate calculated by the motor thermal model. If you are using brake, install a motor thermistor or allow sufficient restart delay (parameter 4M).
Brake
When brake is selected, the EMX3 uses DC injection to slow the motor.
EMX3 braking:
Does not require the use of a DC brake contactor
Controls all three phases so that the braking currents and associated heating are evenly distributed through the motor.
Braking has two stages:
1.
Pre-brake: provides an intermediate level of braking to slow motor speed to a point where full brake can be operated successfully (approximately 70% speed).
2.
Full brake: brake provides maximum braking torque but is ineffective at speeds greater than approximately 70%.
To configure the EMX3 for brake operation:
1.
Set parameter 2I for the desired stopping time duration (1). This is the total braking time and must be set sufficiently longer than the brake time (parameter 2M) to allow the pre-braking stage to reduce motor speed to approximately 70%. If the stop time is too short, braking will not be successful and the motor will coast to stop.
2.
Set Brake Time (parameter 2M) to approximately one quarter of the programmed Stop Time. This sets the time for the Full Brake stage (2).
3.
Adjust the Brake Torque (parameter 2L) so that the desired stopping performance is achieved. If set too low, the motor will not stop completely and will coast to stop by the end of the braking period.

NOTE
When using DC brake, the mains supply must be connected to the soft starter (input terminals L1, L2, L3) in positive phase sequence and parameter 4G Phase Sequence must be set to Positive only.
NOTE
For loads which may vary between braking cycles, install a zero speed sensor to ensure that the soft starter ends DC braking when the motor stops. This avoids unnecessary heating of the motor.
For more information on using the EMX3 with an external speed sensor (eg for applications with variable load during the braking cycle), refer to DC Brake with External Zero Speed Sensor.
710-04840-00J EMX3 User Manual Page 35
OPERATION
7.4 Jog Operation
Jog runs the motor at reduced speed, to allow alignment of the load or to assist servicing. The motor can be jogged in either forward or reverse direction.
CAUTION
Slow speed running is not intended for continuous operation due to reduced motor cooling.
Jog operation causes the motor to heat faster than the rate calculated by the motor thermal model. If you are using jog, install a motor thermistor or allow sufficient restart delay (parameter 4M)
NOTE
Soft start and soft stop are not available during jog operation.
Jog is only available for the primary motor. For more information on primary and secondary motor sets, refer to Secondary motor set.
The maximum available torque for jog forward is approximately 50%~75% of motor full load torque (FLT) depending on the motor. The torque when the motor is jogged in reverse is approximately 25% to 50% of FLT.
Parameter 15E controls how much of the maximum available jog torque the soft starter will apply to the motor.

To activate jog operation, use either a programmable input (refer to parameters 6A and 6F (will operate only in
Remote Mode) or a shortcut key (parameters 8B and 8C).
To stop a jog operation, perform one of the following:
Remove the jog command.
Press the STOP button on the keypad.
Activate Emergency Stop using the keypad programmable inputs.
Jog will recommence at the end of a restart delay if the jog command is still present. All other commands except the above, will be ignored during jog operation.
7.5 Inside Delta Operation
Adaptive Control, Jog, Brake and PowerThrough functions are not supported with inside delta (six-wire) operation. If these functions are programmed when the starter is connected inside delta the behaviour is as given below:
Adaptive Control Start
Adaptive Control Stop
Jog
Brake
PowerThrough
The starter performs a constant current start.
The starter performs a TVR soft stop if parameter 2I Stop Time is >0 secs. If parameter 2I is set to 0 secs the starter performs a coast to stop.
The starter issues a warning with the error message Unsupported Option.
The starter performs a coast to stop.
The starter trips with the error message Lx-Tx Shorted.
NOTE
When connected in inside delta, current imbalance is the only phase loss protection that is active during run. Do not disable current imbalance protection (parameter 4H) during inside delta operation.

9 Motor Data-2
The EMX3 can support two different starting and stopping motor data sets.
To use the EMX3 with two separate motors (such as a duty-standby configuration), use parameter 9A to select dual thermal modelling and configure parameters 9B~9E to suit the second motor.
To use the EMX3 with two different motor data sets for the same motor (for dual speed motors or applications where starting conditions may vary), use parameter 9A to select a single thermal model, and configure the starting and stopping profiles as required in parameters 10A~10G. The soft starter will ignore parameters 9B~9E and will use settings from the primary motor.
To select the secondary motor data set, a programmable input must be configured to parameter set selection
(parameters 6A and 6F) and the input must be active when the soft starter receives a start signal.
NOTE
You can only choose which motor data set to use while the soft starter is stopped.

APPLICATION EXAMPLES
9.5 DC Brake with External Zero Speed Sensor
For loads which may vary between braking cycles, there are benefits in using an external zero-speed sensor to interface with the EMX3 for brake shut-off. This control method ensures that the EMX3 braking will always shut off when the motor has reached a standstill, thus avoiding unnecessary motor heating.
The following schematic diagram shows how you can use a zero-speed sensor with the EMX3 to turn the brake function off at motor standstill. The zero-speed sensor (-A2) is often referred to as an under-speed detector. Its internal contact is open at zero-speed and closed at any speed above zero-speed. Once the motor has reached a standstill, the EMX3 will go into Emergency Stop mode and remain in this state until the next start command is given
(ie next application of –KA1).
The EMX3 must be operated in remote mode and parameter 6A Input A Function must be set to emergency stop.
CAUTION
If the brake torque is set too high, the motor will stop before the end of the brake time and the motor will suffer unnecessary heating which could result in damage. Careful configuration is required to ensure safe operation of the starter and motor.
A high brake torque setting can result in peak currents up to motor DOL being drawn while the motor is stopping.
Ensure protection fuses installed in the motor branch circuit are selected appropriately.
CAUTION
Brake operation causes the motor to heat faster than the rate calculated by the motor thermal model. If you are using brake, install a motor thermistor or allow sufficient restart delay (parameter 4M).

APPLICATION EXAMPLES
NOTE
When using DC brake, the mains supply must be connected to the soft starter (input terminals L1, L2, L3) in positive phase sequence and parameter 4G Phase Sequence must be set to Positive only.
CAUTION
If the brake torque is set too high, the motor will stop before the end of the brake time and the motor will suffer unnecessary heating which could result in damage. Careful configuration is required to ensure safe operation of the starter and motor.
A high brake torque setting can result in peak currents up to motor DOL being drawn while the motor is stopping.
Ensure protection fuses installed in the motor branch circuit are selected appropriately.
9.6 Soft Braking
For applications with high inertia and/or a variable load, the EMX3 can be configured for soft braking.
In this application the EMX3 is employed with forward run and braking contactors. When the EMX3 receives a start signal (pushbutton S1), it closes the forward run contactor (KM1) and controls the motor according to the programmed primary motor settings.
When the EMX3 receives a stop signal (pushbutton S2), it opens the forward run contactor (KM1) and closes the braking contactor (KM2) after a delay of approximately 2-3 seconds (KT1). KA3 is also closed to activate the secondary motor settings, which should be user programmed for the desired stopping performance characteristics.
When motor speed approaches zero, the zero speed detector (A2) stops the soft starter and opens the braking contactor (KM2).

710-04840-00J EMX3 User Manual Page 67
APPLICATION EXAMPLES
9.7 Two-Speed Motor
The EMX3 can be configured for control of dual speed Dahlander type motors, using a high speed contactor (KM1), low speed contactor (KM2) and a star contactor (KM3).
NOTE
Pole Amplitude Modulated (PAM) motors alter the speed by effectively changing the stator frequency using external winding configuration. Soft starters are not suitable for use with this type of two-speed motor.
When the soft starter receives a high speed start signal, it closes the high speed contactor (KM1) and star contactor
(KM3), then controls the motor according to the primary motor settings.
When the soft starter receives a low speed start signal, it closes the low speed contactor (KM2). This closes Input A and the EMX3 controls the motor according to the secondary motor settings.

TROUBLESHOOTING
Section 10 Troubleshooting
10.1 Protection Responses
When a protection condition is detected, the EMX3 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 EMX3 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 keypad or activate the Reset remote input.
If the EMX3 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 Protection Settings and parameter group 16 Protection Action, other settings are built-in system protections and cannot be set or adjusted.

TROUBLESHOOTING
10.3 General Faults
This table describes situations where the soft starter does not operate as expected but does not trip or give a warning.
Symptom
Starter "Not Ready"
The soft starter does not respond to the START or RESET button on the keypad.
The soft starter does not respond to commands from the control inputs.
The soft starter does not respond to a start command from either the local or remote controls.
Probable Cause
Check Input A (C53, C54). The emergency stop function may be active. If parameter 6A or 6F is set to Emergency Stop and there is an open circuit on the corresponding input, the EMX3 will not start.
The soft starter may be in Remote control mode. When the soft starter is in
Remote control mode, the Local LED on the starter is off. Press the
LCL/RMT button once to change to Local control.
The soft starter may be in Local control mode. When the soft starter is in
Local control mode, the Local LED on the starter is on. Press the LCL/RMT button once to change to Remote control.
The control wiring may be incorrect. Check that the remote start, stop and reset inputs are configured correctly (refer to
details).
The signals to the remote inputs may be incorrect. Test the signalling by activating each input signal in turn. The appropriate remote control input
LED should activate on the starter.
The soft starter will only execute a start command from the remote inputs if the remote stop and reset inputs are closed.
The soft starter may be waiting for the restart delay to elapse. The length of the restart delay is controlled by parameter 4M Restart Delay.
The motor may be too hot to permit a start. If parameter 4N Motor
Temperature Check is set to Check, the soft starter will only permit a start when it calculates that the motor has sufficient thermal capacity to complete the start successfully. Wait for the motor to cool before attempting another start.
The emergency stop function may be active. If parameter 6A or 6F is set to
Emergency Stop and there is an open circuit on the corresponding input, the
EMX3 will not start. If the emergency stop situation has been resolved, close the circuit on the input.
NOTE
Parameter 6Q Local/Remote controls when the LCL/RMT button is enabled.
The remote 2-wire start signal must be removed and reapplied for a re-start. A reset does not occur after an
Auto-Reset, when using a remote two-wire control.
Remote start/stop command is overriding Auto Start/Stop settings when using remote two-wire control.
Non-resettable Thermistor Cct trip, when there is a link between the thermistor input B4, B5 or when the motor thermistor connected between B4, B5 is permanently removed.
The soft starter does not control the motor correctly during starting.
Auto Start/Stop function should only be used in Remote mode, 3 and 4-wire control.
The thermistor input is enabled once a link is fitted and short circuit protection has activated.
Remove the link then load the default parameter set. This will disable the thermistor input and clear the trip.
Place a 1k2 resistor across the thermistor input.
Turn thermistor protection to 'Log only' (parameter 16I).
Start performance may be unstable when using a low Motor Full Load
Current setting (parameter 1A). This can affect use on a small test motor with full load current between 5 A and 50 A.
Power factor correction (PFC) capacitors must be installed on the supply side of the soft starter. To control a dedicated PFC capacitor contactor, connect the contactor to run relay terminals.
Page 74 EMX3 User Manual 710-04840-00J
TROUBLESHOOTING
Motor does not reach full speed. If the start current is too low, the motor will not produce enough torque to accelerate to full speed. The soft starter may trip on excess start time.
NOTE
Make sure the motor starting parameters are appropriate for the application and that you are using the intended motor starting profile. If parameter 6A or 6F is set to Motor Set Select, check that the corresponding input is in the expected state.
The load may be jammed. Check the load for severe overloading or a locked rotor situation.
Erratic motor operation.
Erratic and noisy motor operation If the soft starter is connected to the motor using inside delta configuration, the soft starter may not be correctly detecting the connection. Contact your local supplier for advice.
Soft stop ends too quickly.
The SCRs in the EMX3 require at least 5 A of current to latch. If you are testing the soft starter on a motor with full load current less than 5 A, the
SCRs may not latch correctly.
Adaptive Control, brake, jog and
PowerThrough functions not working
The soft stop settings may not be appropriate for the motor and load.
Review the settings of parameters 2H, 2I, 10H and 10I.
If the motor is very lightly loaded, soft stop will have limited effect.
These features are only available with in-line installation. If the EMX3 is installed inside delta, these features will not operate.
After selecting Adaptive Control the motor used an ordinary start and/or the second start was different to the first.
PowerThrough does not operate when selected.
Starter "awaiting data"
The first Adaptive Control start is constant current so that the starter can learn from the motor characteristics. Subsequent starts use Adaptive
Control.
The starter will trip on Lx-Tx Shorted on the first start attempt after control power is applied. PowerThrough will not operate if control power is cycled between starts.
The keypad is not receiving data from the control PCB. Check the cable connection and the fitting of the display on the starter.
Corrupted text shown on keypad display.
Display is distorted
Parameter settings cannot be stored.
Starter reports "Power On" when
Run Simulation is activated.
The keypad may not be screwed down, resulting in an intermittent connection. Screw down the keypad or hold squarely in place.
Check that the keypad has not been screwed down too tightly. Loosen screws slightly.
Make sure you are saving the new value by pressing the STORE button after adjusting a parameter setting. If you press EXIT, the change will not be saved.
Check that the adjustment lock (parameter 15B) is turned off. If the adjustment lock is on, settings can be viewed but not changed. You need to know the security access code to change the adjustment lock setting.
The EEPROM may be faulty on the keypad. A faulty EEPROM will also trip the soft starter, and the keypad will display the message Parameter Out Of
Range. Contact your local supplier for advice.
The soft starter will not activate Run Simulation with three-phase power connected. This prevents unintentional direct on-line (DOL) start.

BUS BAR ADJUSTMENT PROCEDURE
Section 12 Bus bar Adjustment Procedure
The bus bars on non-bypassed models EMX3-0360C ~ EMX3-1600C can be adjusted for top or bottom input and output as required.
NOTE
Many electronic components are sensitive to static electricity. Voltages so low that they cannot be felt, seen or heard, can reduce the life, affect performance, or completely destroy sensitive electronic components.
When performing service, proper ESD equipment should be used to prevent possible damage from occurring.
All units are manufactured with input and output bus bars at the bottom of the unit as standard. The input and/or output bus bars can be moved to the top of the unit if required.
1.
Remove all wiring and links from the soft starter before dismantling the unit.
2.
Remove the unit cover (4 screws).
3.
Remove the keypad faceplate, then gently remove the keypad
(2 screws).
4.
Remove the control terminal plugs.
5.
Gently fold the main plastic away from the starter (12 screws).
6.
Unplug the keypad loom from CON 1 (see note).
7.
Label each SCR firing loom with the number of the corresponding terminal on the backplane PCB, then unplug the looms.
8.
Unplug the thermistor, fan and current transformer wires from the model board.
9.
Remove the plastic tray from the starter (four screws).
NOTE
Remove the main plastic slowly to avoid damaging the keypad wiring loom which runs between the main plastic and the backplane PCB.
10.
Unscrew and remove the magnetic bypass plates (models
EMX3-0620C to EMX3-1600C only).
11.
Remove the current transformer assembly (three screws).
12.
Identify which bus bars are to be moved. Remove the bolts holding these bus bars in place then slide the bus bars out through the bottom of the starter (four bolts per bus bar).
Page 88
13.
Slide the bus bars in through the top of the starter. For input bus bars, the short curved end should be outside the starter. For output bus bars, the unthreaded hole should be outside the starter.
14.
Replace the dome washers with the flat face towards the bus bar, then tighten the bolts holding the bus bars in place to 20 Nm.
15.
Place the current transformer assembly over the input bus bars and screw the assembly to the body of the starter (see note).
16.
Run all wiring to the side of the starter and secure with cable ties.Run all wiring to the side of the starter and secure with cable ties.
NOTE
If moving the input bus bars, the current transformers (CTs) must also be reconfigured.
1.
Label the CTs L1, L2 and L3 (L1 is leftmost when looking from the front of the starter). Remove the cable ties and unscrew the CTs from the bracket.
2.
Move the CT bracket to the top of the starter. Position the CTs for the correct phases, then screw the CTs to the bracket. For models EMX3-0360C ~ EMX3-0930C, the CTs must be placed on an angle (the left hand legs of each CT will be on the top row of holes and the right hand legs will be on the bottom tabs).
