Receiving and handling

Introduction

The SH31 offers acceleration and deceleration control of standard three-phase asynchronous induction (squirrel cage) motors. The SH31 controls the motor performance based on the motor torque rather than simple voltage or current based control. Advanced control algorithms are incorporated to help smooth rotation throughout the starting ramp and reducing mechanical instability at the end of starting.

A digital keypad display is provided for soft starter setup and motor performance display.

The SH31 is available in 15 current ratings from 17 to 590 A. SH31 are rated for use from 208 to 600 V motors, and are self-adjusting for a 50 or 60 Hz supply frequency.

This user manual covers the technical characteristics, specifications, installation, wiring, programming, and troubleshooting of SH31.

Receiving and Preliminary Inspection

Before installing the SH31 soft starter, read this manual and follow all precautions.

Before removing the SH31 soft starter from its packing material, verify that the packing carton is not damaged from shipping. Damage to the packing carton usually indicates improper handling. If any damage is found, notify the carrier and your BLEMO representative.

After removing the SH31 soft starter from its packaging, inspect it for damage. If any shipping damage is found, notify the carrier and your sales representative. Verify that the SH31 soft starter nameplate and label conform to the packing slip and corresponding purchase order.

WARNING

DAMAGED SOFT STARTER EQUIPMENT

Do not operate or install any soft starter that appears damaged.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Storing and Shipping

If the SH31 soft starter is not being immediately installed, store it in a clean, dry area where the ambient temperature is between -25° C and

+70°C (-13°F and +158°F).

If the SH31 soft starter must be shipped to another location, use the original shipping material and carton to help protect it.

Receiving and handling

Handling the soft starter

Hoisting the SH31

The SH31 range comprises 5 frame sizes, with various weights and dimensions.

Small soft starters can be removed from their packaging and installed without a handling device. A handling device must be used from

SH31-110/4; for this reason they are supplied with lifting holes.

WARNING

HANDLING AND LIFTING HAZARD

Keep the area below any equipment being lifted clear of all personnel and property. Use the lifting method as shown below.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Do not remove the SH31 from the carton until it is at the final installation site. Handle the soft starter carefully after removing it from the carton to avoid damage to the internal components, frame, or exterior. Once removed from the carton, the soft starter can be handled:

• With a hoist. When hoisting the soft starter, attach a spreader bar to the two lifting holes on top as shown below.

• In a horizontal position, with the back of the soft starter resting on a pallet.

Selection

Torque characteristic

Ts and Is: Direct on line starting of an asynchronous motor.

Ts1: Total torque range available with an SH31, which is dependent on the limiting current

ILt

, page 51 .

The progression of the soft starter is controlled by the motor torque within this range.

Tr: Resistive torque, which must always be less than the Ts1 torque.

Soft starter selection

S1 motor duty corresponds to starting followed by operation at constant load enabling the thermal stability to be reached.

S4 motor duty corresponds to a cycle comprising starting, operation at constant load and an idle period. This cycle is characterized by a load factor.

The SH31 must be selected depending on the type of application ("standard" or "severe") and the nominal power of the motor. "Standard" or "severe" applications define the limiting values of the current and the cycle for motor duties S1 and S4. These duties are described in the

IEC 60034-1.

Standard application

Example: centrifugal pump

In standard application, the SH31 is designed to provide:

• in S1 duty: starting at 3.5

In

for 40 seconds from a cold state.

• in S4 duty: a load factor of 90% and n starts per hour (see table below), with 3.5 In for 20 seconds or an equivalent thermal cycle.

In this case, the motor thermal protection must conform to protection class 10.

Mounting Precautions

Follow these precautions when mounting the SH31 soft starter:

• The soft starter is compliant with pollution Degree 2 as defined in NEMA ICS1-1 or IEC 60664-1.

• For environment pollution degree 3 install the product inside a cabinet type 12 or IP54.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

SH31 soft starters are open devices and must be mounted in a suitable enclosure.

Failure to follow these instructions will result in death or serious injury.

• The SH31 soft starter generates heat and must be properly ventilated. Refer to "Thermal considerations for sizing enclosures” page

19

to determine power dissipated.

• When several soft starters are installed in a control panel, arrange them in a row. Do not stack soft starters. Heat generated from the bottom soft starter can adversely affect the ambient temperature around the top soft starter.

• Install the SH31 vertically, within ± 10° (other p ositions are not allowed).

• Do not place it close to heating elements. Leave sufficient free space so that the air required for cooling purposes can circulate from the bottom to the top of the unit.

• Electrical current through the SH31 will result in heat losses that must be dissipated into the ambient air immediately surrounding the soft starter. To help prevent a thermal fault, provide sufficient enclosure cooling and/or ventilation to limit the ambient temperature around the soft starter.

Mounting in a General Purpose Metal Enclosure

Observe the mounting recommendations on the previous page.

To help proper air circulation in the soft starter:

• Install ventilation grilles.

• Verify that ventilation is adequate: if not install a forced ventilation unit, with a filter if necessary.

Derate the soft starter current

Follow the instructions in this section in order to meet NEMA Type 12 (IP54) degree of protection.

Do not use insulated or non-metallic enclosures as they have poor thermal conduction. Provide a stirring fan to circulate air inside the enclosure and to help prevent hot spots in the soft starter. This allows operation of the soft starter in an enclosure with a maximum internal temperature of 60°C (140°F). Ensure that the ambien t temperature around the soft starters does not exceed this limit.

Thermal considerations for sizing enclosures

When mounting the SH31 soft starter in an enclosure, use the enclosure manufacturers’ recommendations for proper sizing based on thermal considerations. For this, it is necessary to sum the power dissipated by each device in the enclosure. Table hereafter lists the steady state and starting power dissipations for the SH31 soft starter, operating at rated current.

Thermal protection

Soft starter thermal protection

The thermal protection is provided by the temperature sensor installed on the heatsink.

Motor thermal protection

Standard IEC 60947-4-2 defines the protection classes giving the starting capacities of the motor (warm or cold start) without thermal faults.

Different protection classes are given for a COLD state (corresponding to a stabilized motor thermal state, switched off) and for a WARM state (corresponding to a stabilized motor thermal state, at nominal power).

• The soft starter is factory set to protection class 10.

• This protection class can be modified using

tHP

parameter in

SEt

menu.

• The motor thermal state is stored in memory. No estimate of motor cooling is calculated while power of the control part is off.

• An overload alarm is activated if motor thermal state exceeds 110%.

• A thermal trip

OLF

stops the motor if motor thermal state exceeds 125%.

• If the thermal protection has not been disabled, the thermal trip can be indicated by a relay depending on output assignment.

• After the motor has stopped or the soft starter has been switched off, the thermal state is saved. At next start or switch on, the thermal protection value is restored.

• If a special motor is used (explosion proof, submersible, etc.), the thermal protection should be provided by PTC probes.

CAUTION

RISK OF DAMAGE TO THE MOTOR

The use of external overload protection is required under the following conditions:

• Running multiple motors

• Running motors rated at less than 40% of the nominal soft starter current

• Using motor switching

• Using special motor (explosion proof, submersible, etc...)

Failure to follow these instructions can result in equipment damage.

Installation Precautions

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Read and understand this manual before installing or operating the SH31. Installation, adjustment, repair, and maintenance must be performed by qualified personnel.

• The user is responsible for compliance with all international and national electrical code requirements with respect to grounding of all equipment.

• Many parts of this soft starter, including the printed circuit boards, operate at the line voltage. DO NOT TOUCH. Use only electrically insulated tools.

• DO NOT touch unshielded components or terminal strip screw connections with voltage present.

• Before servicing the soft starter:

- Disconnect all power, including external control power that may be present.

- Place a “DO NOT TURN ON” label on all power disconnects.

- Lock all power disconnects in the open position.

• Install and close all covers before applying power or starting and stopping the soft starter.

Failure to follow these instructions will result in death or serious injury.

Good wiring practice requires the separation of control circuit wiring from all power (line and load) wiring. Power wiring to the motor must have the maximum possible separation from all other power wiring. Do not run them in the same conduit. This separation reduces the possibility of coupling electrical noise between circuits.

Follow these precautions when installing the SH31 soft starter:

• Voltage and frequency specifications for the input line must match the soft starter configuration.

• A disconnect switch must be installed between the input line and the soft starter.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• The solid state switches of the SH31 soft starter’s power circuit do not provide complete isolation from the AC line. Due to leakage currents through the solid-state switches, hazardous voltages can be present on the soft starter load-side power circuit whenever power is applied to the line side of the soft starter.

• Disconnect all power before servicing the soft starter or motor.

Failure to follow these instructions will result in death or serious injury.

• When using an isolation contactor, the contactor must close before or at the same time as the application of the soft starter run command. If line power is not detected at the L1, L2, and L3 terminals of the soft starter within 500 ms of this run command, a Phase

Failure trip will occur.

• External overcurrent protection devices (OCPD), either fuses or a circuit breaker, must be installed on the line-side connections of the SH31 soft starter. The maximum recommended OCPD rating, along with the associated soft starter short circuit withstand rating, is listed on page

84

.

26

Wiring

WARNING

INADEQUATE OVERCURRENT PROTECTION

• An overcurrent protective device must be installed on the line-side of the SH31 to achieve published short-circuit withstand ratings.

• Do not exceed the maximum overcurrent protective device ratings shown on page

84

.

• Do not connect the soft starter to a power feeder whose short circuit capacity exceeds the soft starter short circuit withstand rating shown on page

84

.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

• Power factor correction capacitors should not be connected to a motor controlled by an SH31 soft starter. If power factor correction is required, the capacitors must be located on the line-side of the soft starter. A separate contactor should be used to switch the capacitors off when the motor is off, or during acceleration and deceleration. Refer to bulletin No 8638PD9603.

CAUTION

RISK OF DAMAGE TO THE SOFT STARTER

• Do not connect power factor correction capacitors to the load-side power circuit of the SH31.

• Do not connect loads other than motors (for example transformers and resistors are forbidden).

Failure to follow these instructions can result in equipment damage.

• The SH31 uses solid-state power switches to control motor power. When checking the condition of conductor or motor insulation, do not connect the high potential dielectric test equipment or insulation resistance tester to the soft starter since the test voltages used may damage the soft starter. Always disconnect the soft starter from the conductors or motor before performing such tests.

CAUTION

RISK OF DAMAGE TO THE SOFT STARTER

• Do not perform high potential dielectric tests on circuits while the circuits are connected to the SH31 soft starter.

• Any circuit requiring high potential dielectric tests must be disconnected from the soft starter prior to performing the test.

Failure to follow these instructions can result in equipment damage.

• The SH31 contains electronic circuitry to detect and signal when the solid-state switches have become inoperable.

• Since the solid-state switches may be incapable of completely blocking the motor power should the soft starter detect a fault, auxiliary isolation on the line side of the soft starter is required. Use either a circuit breaker equipped with a shunt trip coil or an electromagnetic contactor. Connect the isolation device to the detected fault relay of the soft starter so that it opens the soft starter power circuit in the event of a soft starter trip. The isolation device must be capable of interrupting motor locked rotor current.

27

Wiring

Refer to application diagrams that display the logic controlling the isolation device via the detected fault relay.

CAUTION

MOTOR OVERHEATING HAZARD

If the solid-state switches on the SH31 become inoperable, single-phase operation of the motor can result.

• Use an isolation device consisting of either a circuit breaker equipped with a shunt trip coil or an electromagnetic contactor to open the line-side of the soft starter.

• The isolation device must be capable of interrupting the motor locked rotor current.

• Connect the detected fault relay of the soft starter to open the isolation device in the event of a soft starter trip.

Failure to follow these instructions can result in injury or equipment damage.

WARNING

INADEQUATE SYSTEM GROUNDING- BRANCH CIRCUIT CONDUCTOR HAZARD

If system grounding is not adequate for ground fault levels, use properly coordinated external ground fault protection. Possible solutions include:

• Time delay fuses coordinated to 125% of motor FLA.

• A properly coordinated external overload relay.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

System Grounding

If system grounding is not adequate to handle ground trip levels which can exceed 1300% of motor full load amps (Motor FLA), then this device may not protect the branch circuit conductors. In this case, external ground trip protection must be properly coordinated.

Recommended solutions include:

• Time delay fuses coordinated to 125% of motor FLA. The fuses listed in the chapter Branch circuit protection are sized to provide proper coordination and may be used for applications that do not require start times longer than 50 seconds at 300% current limit or

20 seconds at 500% current limit.

• External overload relay. For multi-motor applications, applications in which motor does not match the soft starter size, or applications that use a full voltage bypass scheme, an external overload relay can be coordinated to protect conductors from a high-impedance ground trip.

General wiring practices

When wiring SH31 soft starter, follow the wiring practices required by national and local electrical codes. In addition, follow these guidelines:

• Use metallic conduit for all soft starter wiring. Do not run control and power wiring in the same conduit.

• Separate metallic conduits carrying power wiring or low-level control wiring by at least 80 mm (3 in).

• Separate non-metallic conduits or cable trays used to carry power wiring from metallic conduit carrying low-level control wiring by at least 305 mm (12 in).

• Always cross power and control wiring at right angles.

• Keep the control circuits away from the power cables.

Adaptation to line input

The control circuit is completely independent of the power circuit. To apply control voltage, follow the instructions on the label located on the soft starter terminal strip. Connect single phase voltage of 110 or 230 Vac supply to terminals CL1 and CL2.

The power circuit adapts automatically to the input line voltage and frequency over a range of 230 to 440 V for SH31-.../4 soft starters, and over a range of 208 to 600 V for SH31-.../6 soft starters.

Wiring - control terminals

Types of command

LI1 stop behavior

LI1 assignment is stop and cannot be changed by HMI or serial link.

This input is active on level (Low level (0) = stop).

RUN and START management

RUN and START can only be assigned to LI2 (not LI3).

In 2-wire control

On power-up or on manual trip reset, the motor will restart if the RUN command is present.

Control supply

LI2

Motor

In 3-wire control

On power-up or a manual trip reset or after a stop command, or a change of assignment, the motor can only be powered once the START input has been opened (state 0) followed by a new pulse (state 1).

When switching from remote command to local command, with Run order present on the terminal control, the motor doesn’t start in 3-wire control: need to remove Run order and apply it again.

Selection process

The selection process takes you through three levels:

1-Scroll to a parameter menu and press the ENT key.

2-Scroll to a specific parameter and press the ENT key.

3-Scroll to a value and press the ENT key to save the value. A parameter value becomes valid and takes effect immediately, before you press the ENT key.

This means that, if for example you increase the current limit during the start process, the motor current will increase immediately (until

15 seconds maximum). Once you find the correct value, you can either decide to store it (press the ENT key) or return the SH31 to its previous value (press the ESC key), or wait 15 seconds.

Preliminary recommendations

WARNING

LOSS OF CONTROL

• The designer of any control scheme must

- consider the potential failure modes of control paths and, for certain critical control functions,

- provide a means to achieve a safe state during and after a path failure.

Examples of critical control functions are emergency stop and overtravel stop.

• Separate or redundant control paths must be provided for critical control functions.

• System control paths may include communication links. Consideration must be given to the implications of unanticipated transmission delays or failures of the link. (1)

• Each implementation of an SH31 soft starter must be individually and thoroughly tested for proper operation before being placed into service.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

(1) For additional information, refer to NEMA ICS 1.1 (latest edition), “Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control”.

When changing the factory configuration, record your parameter settings in the Parameter Index and Modbus addresses table, starting

page

"Easy start up" level - factory setting

Access to basic parameters which define the characteristics of the application to manage: acceleration ramp, boost level.

"Advanced level"

Access to dedicated parameters which define the characteristics of the motor protections, interface, communication,…

This selection will add some menus and, in the particular case of Monitoring menu, it will add some parameters.

Menu selection: "Easy start up" level or "Advanced" level

1. Scroll up or down using the forward and backward keys until you reach

conF

menu and press the ENT key. This enters Configuration menu.

2. Scroll up or down using the forward and backward keys until you reach

Name

Logic input 2 or logic input 3

Value

LIL

: Forced Local command

The local remote input is active at level 1.

When the input local remote is active, the active command channel is the local channel.

When the local force function is active from a Logic input, the parameters can only be written by the local HMI or the external keypad. If written by Modbus function 6 or 16, the exception 1 bad function is sent back.

When the local force function is active Modbus command word, parameters can be written also by Modbus.

The Logic input assign to "Forced local command" has the priority on bit 15 from Modbus command word. If LI3 is assigned to LIL and

LI3=1, even if bit 15=1 the "Forced local command" is active.

When CTRL = Modbus and LI force local command activated, then a Modbus request 6 or 16 sends back an exception code 1 illegal function.

When on Modbus, only LI1 stop is taken into account.

Modbus Function

This section describes the connection to the bus or network, signaling, diagnostics, and configuration of the communication-specific parameters via the 7-segment LED display.

It also describes the communication services of the Modbus protocol.

Modbus Protocol

The transmission mode used is RTU mode. The frame contains no message header byte, nor end of message bytes.

It is defined as follows:

Slave address

Request code Data CRC16

The data is transmitted in binary code.

CRC16: cyclical redundancy check.

The end of the frame is detected on a silence greater than or equal to 3 characters.

Principle

The Modbus protocol is a master-slave protocol.

Master Only one device can transmit on the line at any time.

The master manages the exchanges and only it can take the initiative.

It interrogates each of the slaves in succession.

No slave can send a message unless it is invited to do so.

The master repeats the question when there is an incorrect exchange, and declares the interrogated slave absent if no response is received within a given time period.

If a slave does not understand a message, it sends an exception response to the master. The master may or may not repeat the request.

Slave i Slave j

Direct slave-to-slave communications are not possible.

Slave k

For slave-to-slave communication, the application software must therefore be designed to interrogate a slave and send back data received to the other slave.

Two types of dialogue are possible between master and slaves:

• the master sends a request to a slave and waits for its response

• the master sends a request to all slaves without waiting for a response (broadcasting principle)

Addresses

• The soft starter Modbus address can be configured from 1 to 247.

• Address 0 coded in a request sent by the master is reserved for broadcasting. SH31 take account of the request, but do not respond to it.

Supported Modbus functions

The SH31 supports the following Modbus functions.

2 = The bit or word addresses indicated in the request do not exist in the slave

3 = The bit or word values indicated in the request are not permissible in the slave

4 = The slave has started to execute the request but cannot continue to process it completely

CRC16 calculation

The CRC16 is calculated on all the message bytes by applying the following method:

Initialize the CRC (16-bit register) to 16#FFFF.

Enter the first to the last byte of the message:

CRC

Enter

XOR

8 times

<byte> —> CRC

Move the CRC one bit to the right

If the output bit = 1, enter CRC XOR 16#A001—> CRC

End enter

End enter

The CRC obtained will be transmitted with the low order bytes sent first, followed by the high order ones (unlike the other data contained in

Modbus frames).

XOR = exclusive OR.
