NOTE!

It is very important to check if

the Soft-Starter Software is the

same as the above.

ATTENTION!

Please check which type of connection is used to connect the SSW-03 Plus to the motor: standard connection or SSW-03 Plus is connected within the motor Delta connection.

Standard connection with three cables: the line current of the Soft-Starter is equal to the motor current.

SSW-03 Plus is connected within the motor Delta connection with six leads: the line current of the Soft-Starter

is approximately 58% of the motor current.

ATTENTION!

To connect the SSW-03 Plus within the Motor Delta connection, the motor must permit the Delta connection in the desired voltage.

R S T N PE

2.4 - ABOUT THE SSW-03 PLUS

The SSW-03 Plus series is a totally microprocessor controlled Soft-Starter series which controls the starting current of threephase induction motors. In this way mechanical inmpacts on the load and current peaks on the supply network are prevented.

2.4.1 - Introduction

This series includes models from 120 to 1400A, being supplied from 220V, 230V, 240V, 380V, 400V, 415V, 440V, 460V, 480V, 525V or 575V. (The available types are listed in Section 8).

The models up to 205A are fitted with forced cooling and isolated heatsink (thyristor-thyristor modules). The models from 255A up to 1400A have forced cooling and energized heatsink. (Disc thyristors).

The electronic control circuit uses a 16 bit microprocessor with high performance, allowing settings and displaying by means of the interface (keypad + display) of all needed parameters.

Depending on the power, this series (SSW-03 Plus) has 8 different construction forms, as shown in Figure 2.1.

INTRODUCTION

2.4.2 - Simplified Block Diagram of the SSW-03 Plus

In the power stage, the line voltage is controlled by means of 6 SCR’s that allow the variation of the conduction angle of the voltage supplied to the motor.

For the internal supply of the electronics, a linear source is used with several voltages, fed independently of the power supply.

The control board contains the circuits responsible for the control, monitoring and protection of the power components. This board also contains the control and signalling circuit to be used by the user according to its application as a relay output.

All parameters or controls for the operation of the Soft-Starter can be displayed or changed through the HMI.

INSTALLATION

NOTE!

SSW-03 Plus is suppliedwith an extension bus bar toenable the connection of more cables to the SSW-03 Plus input bus bar. Do not use this extension busbar when SSW-03 Plus connection to line supply is made by means of bus bar.

Thedrawing below is orientative. Dependingon the Soft-Starter type, the extension bus bar may have one, two or three holes.

NOTE!

1)The connection cables of the Soft-Starter to the line supply, or the line supply isolation contactor must be able to carry the motor rated current, and the motor connection cables to the Soft-Starter, and/or the bypass contactor must be able to carry 58% of the motor rated current.

2) Due to the high currents and cable cross sections, it is also suggested to use copper bus bar for this type of connection.

3)When 2 poles motors are in full voltage it is necessary a minimum of 25% ofload applied to its axle. When thiscondition can not be taken, a bypass contactor is necessary.

GROUNDING CONNECTIONS

ATTENTION!

The connection of the motor to the Soft-Starter must be realized carefully. Follow strictly the connection diagrams according to the winding types shown in figure 3.5 and item 6.4.1.

If reversal of motor direction of rotation is required, change the Soft-Starter connection to the line supply. Ensure that power is switched OFF while connections are changed.

Do not start motor with wrong P28 content:

OFF = standard connection ON = within the motor delta connection

DANGER!

AC input disconnect: provide an AC input disconnecting switch to switch OFF input power to the Soft-Starter. This device shall disconnect the Soft-Starter from the AC input supply when required (e.g. during maintenance services).

DANGER!

The AC input disconnect cannot be used as an emergency stop device.

DANGER!

Be sure that the AC input power is disconnected before making any terminal connection.

DANGER!

The information below will be a guide to achieve a proper installation. Follow also all applicable local standards for electrical installations.

ATTENTION!

Provide at least 10 in (0.25m) spacing between low voltage wiring and the Soft-Starter. , line or load reactors, AC input power, and AC motor cables.

ATTENTION!

Control of overvoltage in the line that supply the Soft-Starter must be made using protective of surge with voltage of 550Vac (for models 220 - 440Vac) and 680Vac (for models 460 - 575Vac) connection phase to phase, and absortion energy capacity of 80 joules.

Grounding

The Delta Kit is supplied with the SSW-03 Plus.

Copper cables with PVC 70°C (158°F) isolation, with ambient temperature of 40°C (104°F) installed in perforated conduits and not bunched. Non insulated or silver plated bus bars with rounded edges with 1 mm radius with ambient temperature of 40°C (104°F) and bus temperature of 80°C (175°F). For bypass connection use the same cables or bus bars that are used for motor connection. For correct cable dimensioning, consider the installation conditions and the max. permitted voltage drop.

 We do not recommend the use of motors that are operated

in continuous duty with less than 50% of their rated current.

The rated motor current must not be smaller than 30% of the rated current of the Soft-Starter, in order that the overload protection works properly.

When installing the signal and control wiring, please note the following:

Cable cross-section: 0.5...1.5mm2;

Relays, contactors, solenoid valves or breaking coils installed near to Soft-Starters can generate interferences in the control circuit. To eliminate this, you must install RC supressors connected in parallel with the coils of these device, when fed by alternate current and free wheel diodes when fed by direct current.

When an extern HMI is used, the connection cable to the Soft-Starter should be passed through the slot at the bottom of the Soft-Starter.This cable must be laid separate from the other cables existing in the installation, maintaining a distance of 100mm (3.94in) each other.

Max. recommended torque in the terminals X2 and X1: Maximum 0.5 Nm or 4.5lb.in.

The control wiring (X2:1...9) must be laid separate from

the power wiring.

DETAILED PARAMETER DESCRIPTION

1. Set P45 (Pump control) at "On".

2. Set P14 (undercurrent) or set P15 (Undercurrent Time) at "OFF" until the set has finished. After then, program it again.

3. Check the correct direction of rotation of the motor, as indicated ON the pump frame.

4. Set P01 (initial voltage - % UN) to the level so the motor starts to run without vibration.

5. Set P02 (Acceleration Time [s]) to the starting time required by the load. With the manometer in the pipeline, check the pressure increase that must be continuous until the max. required level is reached without overshoots. If overshoots occur, increase the acceleration time to reduce this pressure overshoots at maximum.

6. P03 (Voltage Fall Step - %UN) use this function to cause an immediate pressure drop or a more linear pressure drop during the motor deceleration.

7. P04 (deceleration time) during the motor deceleration check with manometer the pressure drop that must be continuous until the minimum level is reached without the presence of hydraulic ram when the non-return valve is closed. If this occurs, increase the deceleration time until the oscillations are reduced at maximum.

SSW-03 Plus permits two modes of operation: standard connection or connection within the motor delta connection.

P28=OFF - Standard connection uses the Soft-Starter in the normal star or delta line connection.

P28=ON - Motor inside delta connection uses the Soft-Starter connected by the six motor leads in the motor phases.

6.4.1 - P28 - Operation Mode

NOTE!

If no manometer is installed in the pipelines, the hydraulics ram can be observed through the pressure relief valves.

NOTE!

Excessive acceleration or deceleration times can cause motor overheating. Program them for your application as short as possible.

DETAILED PARAMETER DESCRIPTION

Standard connection with three cables: P28=OFF, SoftStarter line current equal to motor current.

Connection within the Motor Delta Connection with six cables: P28=ON, Soft-Starter line current approximately 58%

of the motor current.

For thedelta insideconnection the Soft-Starter SSW-03 is installed separately in each winding of the motor through 6 cables. In thistype of connection the circulating current of the Soft-Starter is only the 58% from the nominal current of the motor. This characteristic changes the relation between the motor nominal current and the nominal current of the Soft-Starter. To know, in this connection, the Soft-Starter can be specified as:

- 1.50 times the nominal current of the motor, during the start;

- 1.73 times the nominal current of the motor, in full voltage.

During the start the relation is lesser because had the common characteristics to this type of connection (inside of the Delta) the Thyristorofthe Soft-Starterneeds to leadthesame currentinalesser cycletime, raisingwiththisthelossesintheThyristorduringthestart.

The standard connection requires less output wiring. The connection within the motor delta connection requires twice the standard connection, but for short distances, it is a cheaper option for Soft-Starter + motor + wiring.

NOTE!

1)When the connection within the motor delta connection is used, as shown in Item 9.9, the connection cables of the SoftStarter to the line supply, or the line supply isolation contactor must be able to carry the motor rated current, and the motor connection cables to the Soft-Starter, and/or the bypass contactor must be able to carry 58% of the motor rated current.

2) Due to the high currents and cable cross sections, it is also suggested to use copper bus bar for this type of connection to connect the Soft-Starter to the line supply.

Ex: How to set P21:

1) Standard Connection

IN of the switch = 170A IN of the motor = 140A

P21 = 82.3%

DETAILED PARAMETER DESCRIPTION

6.5.2 - P25 - Thermal Class of the Motor Protection

The Soft-Starter SSW-03 Plus is fitted with a Thermal Protection. This protection is very efficient for the motor protection. All Soft-Starter SSW-03 Plus models are fitted with this protection and always it is activated, error E04 is displayed and the motor is switched off. This thermal protection has curves that simulate the motor heating and cooling. The calculation is performed through a sophisticated software that estimates the motor temperature by means of the current that is supplied to the motor. The actuation curves of the motor Thermal Protection are according to IEC 60947-4-2 standard. The motor heating and cooling curves are based on long experience of the company with its motors. These curves adopt a standard three-phase motor with IP55 degree of protection. These curves also consider if the motor is cooled during operation or not.

NOTE!

The error E04, motor overload, remains in the memory, even if the CPU is reset, and when the CPU is switched Off, the last value is stored. The value is only decremented with the switch On and the motor Off.

If a Service Factor different from 1.00 is used, the nominal current for the chart (figure 6.10) has to be corrected by the S.F. For example: a motor of In=100A and S.F.=1.15 has 1 x In=115A.

The cooling time of the thermal image depends on the motor power, i. e., for each power, a different cooling time is considered. If a different cooling time is required, this setting can be made at P27. The estimated value for the motor temperature is saved in non-volatile memory always the control board is switched off. Thus, always the control board is switched on, the last saved value will be returned.

Table 6.4 - Multiplication factor for the corrected

Thermal Class times

EXAMPLE:

Correction of the actuation time:

A motor operating at 80% In is switched off and switched on immediately. The starting duty is 3xIn @ 25s. The selected Thermal Class is Class 20 with 39s @ 3xIn. The correction factor for 80% In in the table 6.4 is 0.35. The corrected actuation time is: 0.35 x 39s = 13.7s, the actuation time is reduced from 39s at cold condition to

13.7s. This means that a immediate start is not possible before the thermal image of the motor has been cooled down.

NOTE!

For programming correctly the Thermal Class that should protect the motor against overheating, you must consider the allowed hot locked rotor time. This data is available in the catalog of the motor manufacturer.

EXAMPLE:

Suggestions on how to program the Thermal Class correctly:

Motor data:

Power: 100hp Voltage: 380V Rated current (In): 140A Service factor (S. F.): 1.00 Ip/In: 6.6 Lockedrotor time: 12s at hot (Standard catalog information) Speed: 1780rpm

Data about the motor + load Starting:

Starting by Voltage Ramp, average starting current: 3 x the rated motor current during 25s (3 x In @ 25s).

1) In the cold chart Figure 6.10, we can find the minimum required Thermal Class that allows motor start with reduced voltage: For 3 x In @ 25s, we select the next higher class: 15

2) In the hot chart Figure 6.11, we can find the maximum Thermal Class that the motor will withstand due to the hot locked rotor time: For 6.6 x In @ 12s, we select the next lower Class: 30

6.5.3 - P26 - Motor Service Factor

It sets the Motor Service Factor (SF) according to the

motor nameplate data.

That value defines the load that the motor can drive.

Now it is known that Thermal Class 15 allows cold start and Thermal Class 30 is the upper limit. Thus you must select a Thermal Class between these two Thermal Classes by considering the number of starts per hour and the time interval between motor On-Off procedures.

With a smaller Class selected, the motor protection will increase but, less starts per hour are allowed and longer time intervals between motor On-Off procedures are required.

On the other hand with a higher Class selected, the motor might be operated closer to the limit, thus more starts per hour are allowed and shorter time intervals between motor On-Off procedures can be used.

If you are not sure which Thermal Class should be adopted between these two limits, adopt the lowest Thermal Class firstly, and only during practical tests at full load operation select the Class that is more suitable to your requirements, without exceeding the upper limit.

NOTE!

If several Thermal Classes can be applied, program one that is most suitable for your application, protecting your motor according to your duty requirements.

NOTE!

If the motor is equipped with a temperature sensor (PTC or Thermostat) which is used for thermal protection, the thermal class of the SSW-03 Plus can be disabled by setting P21= Off.

Please note that every time you use this function you can reduce the winding life of your motor.

6.5.4 - P27 - Auto-reset of the Thermal motor image

It sets the time for the auto-reset of the thermal motor image. The thermal decrement of the thermal motor image simulates the motor cooling time with load and without load, ON and OFF. The algorithm that realizes this simulation is base on tests applied on WEG motors IP55 standard according to your power programmed in the Soft-Starter parameters. In application, where several starts per hour are required, you can use the auto-reset of the thermal image.
