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.

The EMX4i is not user serviceable. The unit should only be serviced by authorised service personnel. Unauthorised tampering with the unit will void the product warranty.

• 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.

• 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.

2.1 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

The EMX4i is not short circuit proof. After severe overload or short circuit, the operation of the EMX4i should be fully tested by an authorised service

agent.

CAUTION STATEMENTS

GROUNDING AND BRANCH CIRCUIT PROTECTION

WARNING – ACCIDENTAL STARTS

WARNING – STARTER MAY START OR STOP UNEXPECTEDLY

WARNING – DISCONNECT MAINS BEFORE ACCESSING STARTER OR LOAD

CAUTION – MECHANICAL DAMAGE FROM UNEXPECTED RESTART

It is the responsibility of the user or person installing the EMX4i to provide proper grounding and branch circuit protection according to local electrical safety codes.

2.2 Unexpected Operation

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 EMX4i will respond to control commands from various sources, and could start or stop unexpectedly. Always disconnect the soft starter from mains voltage before accessing the starter or load.

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.

The motor could restart after the causes of shutdown are rectified, which may be dangerous for personnel. Always disconnect the soft starter from mains voltage before accessing the starter or load.

The motor could restart 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.

AVERTISSEMENT – DÉMARRAGES ACCIDENTELS

2.3 Avertissements à l'attention des clients canadiens

L'icône AVERTISSEMENT ci-contre signale les informations concernant des risques pouvant entraîner des blessures graves, voire mortelles. Pour votre sécurité, veuillez consulter les avertissements sur cette page ou demander une copie du présent manuel en français auprès de votre distributeur local.

Les zones suivantes sont soumises à des tensions pouvant provoquer des risques de chocs électriques graves, voire mortels :

• Raccordement et câbles d'alimentation AC

• Câbles et raccordements de sortie

• De nombreuses pièces internes du démarreur

• La fonction STOP du démarreur progressif n'isole pas des tensions

dangereuses de la sortie du démarreur. Le démarreur progressif doit être déconnecté par un dispositif d'isolement électrique approprié avant d'accéder aux connexions électriques.

• Les fonctions de protection du démarreur progressif ne concernent que

la protection du moteur. Il relève de la responsabilité de l'utilisateur d'assurer la sécurité des personnes travaillant sur les machines.

• Le démarreur progressif est un appareil conçu pour s'intégrer dans un

système électrique ; il relève donc de la responsabilité du concepteur ou de l'utilisateur de veiller à ce que ce système soit sûr et conçu selon les normes de sécurité locales en vigueur.

Dans certaines installations, des démarrages accidentels peuvent provoquer un risque supplémentaire pour la sécurité des personnes ou endommager les machines contrôlées. Dans de tels cas, il est recommandé de doter l'alimentation du démarreur progressif d'un interrupteur d'isolement et d'un coupe-circuit (par exemple, un disjoncteur) contrôlable à partir d'un système de sécurité externe (par exemple, un arrêt d'urgence, un détecteur de défaut).

CAUTION STATEMENTS

AVERTISSEMENT – LE DÉMARREUR PEUT DÉMARRER OU S'ARRÊTER À TOUT MOMENT

AVERTISSEMENT – DÉCONNECTER L'ALIMENTATION PRINCIPALE AVANT D'ACCÉDER AU DÉMARREUR OU À LA CHARGE

AVERTISSEMENT

L’EMX4i répond aux commandes de contrôle de différentes origines et peut par conséquent démarrer ou s'arrêter à tout moment. Toujours déconnecter le démarreur de la tension secteur avant d'accéder au démarreur ou à la charge.

Le démarreur progressif comporte des protections intégrées qui peuvent déclencher des mises en sécurité dans l'éventualité de défauts et ainsi arrêter le moteur. Des fluctuations de tension, des coupures d'alimentation et des blocages du moteur peuvent produire des mises en sécurité de celui-ci.

Le moteur pourrait redémarrer une fois que les causes de l'arrêt ont été résolues, ce qui pourrait mettre en danger le personnel. Toujours déconnecter le démarreur de la tension secteur avant d'accéder au démarreur ou à la charge.

Ne pas appliquer la tension du secteur au démarreur tant que tout le câblage n'est pas terminé.

Toujours appliquer la tension de commande avant (ou en même temps que) la tension secteur.

Lors du raccordement de l’EMX4i en connexion 6 fils, toujours installer un contacteur principal ou un disjoncteur magnéto-thermique à bobine de déclenchement.

Si l'entrée de démarrage est fermée lorsque la tension de commande est appliquée, le démarreur tentera d'effectuer un démarrage.

Vérifier que l'entrée de démarrage/arrêt est ouverte avant d'appliquer la tension de commande.

Nominal current rating

The soft starter must be the correct size for the motor and the application. Select a soft starter that has a current rating at least equal to the motor's full load

current (nameplate) rating, at the start duty. The soft starter's current rating determines the maximum motor size it can be used

with. The soft starter's rating depends on the number of starts per hour, the length and current level of the start, and the amount of time the soft starter will be off (not passing current) between starts.

The soft starter's current rating is only valid when used in the conditions specified in the AC53b code - the soft starter may have a higher or lower current rating in different operating conditions.

PC software can provide real-time or offline management of soft starters.

• For real-time management in a network of up to 254 starters, the

software must connect to the soft starter via a Modbus TCP or Modbus RTU card. The software can monitor, control and program the starter across the network.

• The software can be used to program the starter via the USB port on the

pumping smart card.

• For offline management, a configuration file generated in the software

can be loaded into the starter via the USB port.

3.8 Main Contactor

A main contactor is recommended to protect the soft starter from voltage disturbances on the network, while stopped. Select a contactor with an AC3 rating greater than or equal to the full load current rating of the connected motor.

Use the main contactor output (33, 34) to control the contactor.

When connecting the EMX4i in inside delta configuration, always install a main contactor or shunt trip circuit breaker.

3.9 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.

CAUTION

3.10 Power Factor Correction

If power factor correction is used, a dedicated contactor should be used to switch in the capacitors.

To use the EMX4i to control power factor correction, connect the PFC contactor to a programmable relay set to Run. When the motor reaches full speed, the relay will close and power factor correction will be switched in. Do not use the soft starter relay output to directly switch in power factor correction.

2 Programmable output (set = Run) 3 Power factor correction contactor 4 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.

3.11 Short Circuit Protection Devices (SCPD)

Fuses may be installed to protect the soft starter or the installation.

Type 1 Coordination

Type 1 coordination requires that, in the event of a short circuit on the output side of a soft starter, the fault must be cleared without risk of injury to personnel. There is no requirement that the soft starter must remain operational after the fault.

HRC fuses (such as Ferraz/Mersen AJT fuses) can be used for Type 1 coordination according to IEC 60947-4-2 standard.

Type 2 Coordination

Type 2 coordination requires that in the event of a short circuit on the output side of a soft starter, the fault must be cleared without risk of injury to personnel or damage to the soft starter.

Semiconductor fuses for Type 2 circuit protection are additional to HRC fuses or MCCBs that form part of the motor branch circuit protection.

.

• The EMX4i will only accept Start and Reset commands from the

designated command source.

• The EMX4i will accept Stop commands from the designated command

source, but can be forced to stop by opening the reset input, or by opening the start/stop input during an auto-start/stop cycle.

• The programmable input can be used to override the selected command

source (refer to parameter 7A

• the reset input must be closed

• the first start must be commanded by a start signal

Timer mode operation is controlled by parameters 4B ~ 4C.

8.4 PowerThrough

PowerThrough allows the soft starter to control the motor even if the soft starter is damaged on one phase. The EMX4i will use two-phase control techniques to soft start and soft stop the motor.

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.

• PowerThrough is only available with in-line installations. If the starter is

installed inside delta, PowerThrough will not operate.

• PowerThrough remains active until '3-Phase Control Only' is reselected.

While operating in PowerThrough, the trip LED will flash and the display will indicate ‘2 Phase - Damaged SCR'.

PowerThrough operation does not support Adaptive Control soft starting or

soft stopping. In PowerThrough, the EMX4i will automatically select constant current soft starting and timed voltage ramp soft stopping. If PowerThrough is enabled, parameters 2C and 2D must be set appropriately.

PowerThrough uses a tworequired when sizing circuit breakers and protection. Contact your local supplier for assistance.

OPERATION

NOTE

CAUTION

8.5 Emergency Mode

Emergency mode allows the EMX4i to run the motor and ignore trip conditions. Emergency mode is controlled via a programmable input (input A 13, 14 or input B

13, 15) and parameter 7A

Input A Function

/7E

Input B Function

must be set to 'Emergency Mode'. A closed circuit across 13, 14 activates emergency mode. When the EMX4i receives a start command, it will continue to run until a stop command is received, ignoring all trips and warnings.

Emergency mode can be used in conjunction with any command source.

Although emergency mode operation satisfies the functionality requirements of Fire Mode, AuCom does not recommend its use in situations that require testing and/or compliance with specific standards as it is not certified.

Continued use of emergency mode is not recommended. Emergency mode may compromise the starter and/or motor life as all protections and trips are disabled.

Using the starter in emergency mode will void the product warranty.

8.6 Auxiliary Trip

An external trip circuit (such as a low pressure alarm switch for a pumping system) can be used to trip the soft starter and stop the motor. The external circuit is connected to a programmable input (input A 13, 14 or input B 13, 15). To control the behaviour of the trip, set the following parameters:

• Parameter 7A

• Parameter 7B

the input trip to when the soft starter is running only.

• Parameter 7C

8.8 Soft Start Methods

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.

Initial Current

(parameter 2C)

Rotor speed (% full speed)

Constant Current with 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

50 EMX4i User Manual 710-14888-00C

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.

Constant Current with 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.

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,

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

Adaptive Control for Starting

In an adaptive control soft start, the EMX4i adjusts the current in order to start the motor within a specified time and using a selected acceleration profile.

The EMX4i will apply the current limit on all soft starts, including adaptive control. If the current limit is too low or the start ramp time (parameter 2B) is too short, the motor may not start successfully.

(parameter 2B)

• Fine-tuning Adaptive Control

If the motor does not start or stop smoothly, adjust the adaptive control gain (parameter 2L). The gain setting determines how much the EMX4i 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.

The EMX4i tunes Adaptive Control to match the motor. Changing the following parameters will reset Adaptive Control and the first start/stop cycle will use constant current start/timed voltage ramp stop: 1B

8.9 Stop Methods

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.

Timed Voltage Ramp Soft Stop

Timed voltage ramp reduces the voltage to the motor gradually over a defined time. This can extend the stopping time of the motor and may avoid transients on generator set supplies.

The load may continue to run after the stop ramp is complete.

1:

Stop Time

Voltage (% full voltage)

(parameter 2J)

Adaptive Control for Stopping

In an adaptive control soft stop, the EMX4i 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.

If adaptive control is selected, the first soft stop will use timed voltage ramp. This allows the EMX4i to learn the characteristics of the connected motor. This motor data is used by the EMX4i during subsequent adaptive control stops.

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.

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.

If replacing a motor connected to an EMX4i programmed for Adaptive Control starting or stopping, the starter will need to learn the characteristics of the new motor. Change the value of parameter 1B

DC Brake

Brake reduces the time required to stop the motor. During braking an increased noise level from the motor may be audible. This is a

normal part of motor braking.

When using DC brake, the mains supply must be connected to the soft starter (input terminals L1, L2, L3) in positive phase sequence.

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.

54 EMX4i User Manual 710-14888-00C

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.

Soft Brake

For applications with high inertia and/or a variable load requiring the maximum possible braking torque, the EMX4i can be configured for soft braking.

The EMX4i uses a changeover relay to control forward run and braking contactors. While braking, the EMX4i reverses the phase sequence to the motor and supplies reduced current, gently slowing the load.

When motor speed approaches zero, the zero speed sensor (A2) stops the soft starter and opens the braking contactor (K2).

Soft braking can be used with both the primary and secondary motor sets, and must be configured separately for each.

The starter can perform a pump clean function before soft starting the motor. This can help dislodge debris from the impeller.

Pump clean starts the motor in reverse then forward direction, then stops the motor. Pump clean can be configured to repeat the process up to 5 times. After the specified number of cleaning cycles, the starter performs the programmed soft start.

Pump clean operation is controlled by the start/stop input (11, 12). A programmable input must be set to pump clean (refer to parameter 7A

The starter can control a reversing contactor, to operate the motor in reverse direction. When reverse operation is selected, the starter will perform a soft start using the opposite phase sequence from normal operation.

Reverse operation is controlled by the start/stop input (11, 12). A programmable input must be set to reverse direction (parameter 7A output must be set to reversing contactor (parameter 8A

NOTE

8.14 Secondary Motor Set

The EMX4i can be programmed with two separate starting and stopping profiles. This allows the soft starter to control the motor in two different starting and stopping configurations.

The secondary motor set is ideal for dual winding (Dahlander) motors, multi-motor applications, or situations where the motor may start in two different conditions (such as loaded and unloaded conveyors).

The secondary motor set can also be used for duty/standby applications.

For duty/standby applications, set parameter 6Q Log Only and install temperature protection for each motor.

To use the secondary motor set, a programmable input must be set to 'Motor Set Select' and the input must be closed when a start command is given (refer to 7A
