1.2. Description of the Equipment

SS7 Series is the 1 st

LS Softstarter generation. It is a new electronic softstarter that integrates most advanced control systems to assure a perfect motor operation at any industrial application.

Outstanding features:

Mounting simplicity and versatility.

Its cabinet format provides a fast installation and easy access to power and control terminals.

All SS7 Series incorporate a unique and common control board for all power ratings.

Control flexibility.

Commissioning is possible via local display unit or PC (PowerCOMS program).

It includes 2 analogue inputs and 5 digital inputs, 3 output relays and 1 analogue output, to provide user with plenty of control possibilities.

RS232/RS485 serial communications are built-in: compatible with communication protocols Modbus, Profibus-DP, DeviceNet, N2-Metasys, etc.

INTERNAL BYPASS.

The new SS7 models offer the Bypass contactors already built in, the need for additional external hardware will be significantly reduced with the result of consequent space savings ( an additional electrical cabinet is not needed). Additionally it reduces installation time and the wiring verification, thus avoiding possible errors in external wiring.

Also, heat dissipation during operation is much less, which effects the corresponding saving in ventilation components in the implemented electrical cabinets. The current measurement of the softstarter will not suffer any change and the internal protections will be completely active, thus ensuring the motor protection all the time.

The internal bypass is automatically switched on after the acceleration has been finished, bridging the internal SCRs but without interrupting the normal operation of the softstarter and the motor.

At the end, the connection of the equipment is easy, safe and effective.

2. INSTALLATION AND CONNECTION

SS7 SERIES

2.1. Environmental Conditions

The maximum ambient/working temperature for the SS7 is 45ºC. The SS7 can be operated in a higher ambient temperature of up to 50ºC by de-rating the soft starter by 2% for every degree over

45ºC.

2.2. Degree of Protection

The SS7 soft starter ingress protection is IP20. This means that the soft starter is protected against finger contact with hazardous or moving parts inside the enclosure, and protection of against ingress of foreign objects with a diameter greater than 12mm.

2.3. Installation of the Softstarter

The SS7 soft starter is designed for vertical mounting.

Input bus bars are located in the top and motor bus bars must be connected at the bottom, except for models SS70009 to SS70090 where both, input and output must be connected at the bottom.

To improve heat dissipation, it is recommended to mount the soft starter on a metal gear plate.

In case of units are installed inside a cabinet, it is required to calculate the corresponding ventilation.

When installed within a cabinet, proper ventilation is to be provided. A minimum of 40mm side clearance and 150mm top and bottom distance is to be kept between soft starters and or side of the enclosure.

Do not install SS7 above any heat source, unless heat airflow is forced out of the cabinet.

SS7 SERIES

2.4. Power Loss Dissipation

The SS7 has a power loss of 3 watts per amp. For example this means that a SS70210 has a power loss of 630 watts at full load.

2.5. Power Connections and Control Wiring

2.5.1. Power Connections

Most electrical wiring regulations require a mains isolator on solid state equipment. The SS7 falls in to this category. This is to ensure there is an air break in the circuit as semiconductors cannot be relied upon to be safe isolation. There are many choices, the most common are thermal magnetic protection with a trip coil in conjunction with a contactor.

Magnetic protection is required to protect the SS7 from damage due in the event of a short circuit within the SS7 or on the output cabling or motor. When faster protection is desired, semiconductor fuses are recommended. The fuses should be mounted as close to the SS7 as possible. Power factor correction capacitors must not be connected after the fuses or on the output of the SS7.

The SS7 protects the motor with electronic overload sensing, so an external overload relay is not necessary. If multiple motors are connected, separate overloads are required for each motor.

An isolator can be fitted after the SS7 but is recommended for off load use only. Whilst a motor isolator is not necessary for the operation of the SS7, site standards or electrical wiring regulations may require this to be installed.

If a contactor is to be fitted, one of the SS7 output relays can be used to energise this on receiving an external start signal. (G7.1 Relay 1 = 11 Instantaneous).

Note: It is absolutely necessary that the installer guaranties the correct observance of the law and the regulations that are in force in those countries or areas where this device is going to be installed.

2.6. Considerations before commissioning the SS7 Softstarter

1. Check for foreign objects in the SS7 cabinet – particularly which left there from installation.

2. Check that the control board supply (L - N, 230VAC ±10%) is connected.

3. Check that the power supply is connected to the terminals L1, L2, L3 and the motor is connected to the terminals U, V, W. Confirm that the supply is according to the SS7 specifications. The motor current should not exceed the SS7 rating.

4. Check all control wiring, close SS7 cabinet and ensure the installation is electrically safe and that it is safe to run the motor.

5. It is recommended that all digital inputs are disconnected before applying voltage to the SS7 for the first time to prevent accidentally starting the motor. It is also recommended not to apply main voltage (3ph~) before commissioning the softstarter.

Note: SS7 Softstarter are configured with START, STOP, RESET from keypad by default.

6. Digital input status can be checked through screen G0: DIG INPUT= X 0 0 0 0 F.

X indicates this digital input is on, 0 indicates the digital input is off.

K indicates PTC input is not active. F indicates PTC input is active.

As default, the digital inputs are disabled G6.1 OPER MODE=1 (LOCAL). This means that the

SS7 start and stop can only be controlled via the display unit pushbuttons.

7. The default configuration for the digital outputs is as follows:

Relay 1: Instantaneous

(Switch ON = SS7 accelerates and Switch OFF= Deceleration of the SS7 is

finished).

Relay 2: Bypass

(Switch ON at end of ramp up and Switch OFF at start of ramp down).

Relay 3: Fault

(Energized on fault conditions).

8. Ensure the stop circuit is open before configuring the SS7 to work in 3-wire mode.

9. Set the motor (rated) nameplate and start/stop parameters, protection and user parameters.

10. Set jumpers as follows:

3.2. SS7 Softstarter with Internal Bypass

LS

The norm IEC60947-4-2 describes classification for Electronic Softstarters.

According to this information, there are two utilisation categories for the Electronics Softstarters, described as follow:

 AC53a: Softstarters which support the nominal current through the SCRs during continuous operation.

 AC53b: Softstarters which support the starting current through the SCRs during the starting while the SCRs will be bypassed during steady status.

Basically, the capacity limitation of Softstarters is mainly thermal limitation. It is important to consider that there are five different factors which will affect to the internal temperature of thyristors: a) Starting Time b) Starting Current. c) Ambient Temperature d) Time at OFF status e) Number of Startings per Hour.

EXAMPLE

110 : AC53b 4.5 – 30 : 330

 

 

Rated Current of the Softstarter under the described conditions: In, (110 Amps)

The thyristors will be bypassed.

Starting Current, as multiple of the nominal current (In), that means: 4.5xIn

Starting Time, in seconds, (30s)

Seconds between the end of starting and the beginning of next starting (10 startings per hour)

7. CONNECTION TERMINALS

SS7 SERIES

The next figure provides the electrical specification of all SS7 control inputs and outputs. Each input and output is individually described below:

 Analogue and digital inputs / outputs.

 Serial Communication (RS232/RS485).

7.1. Control Connection Drawing

Figure 7.1 Connection terminals description (SS7 Standard Softstarter)

CONNECTION TERMINALS

27

SS7 SERIES

7.2. Terminal Description

Control board supply voltage

Input terminals for control board supply voltage (230V +/-10%). Other voltage ratings are available on demand.

Note that the unused terminal between L and N is purely to ensure electrical clearances.

Terminals T1 to T9 / Programmable Output Relays

Selection of their function is made through Group 7 OUTPUTS. Avoid settings that cause relays to switch excessively as this will reduce their life expectancy.

The maximum allowable ratings for the relay outputs are 250V/AC / 10A or 30V/DC 10A.

Terminal T10 / 24VAC for Digital Inputs

This terminal provides the 24V supply for the 5 digital inputs at terminals T11 to T15. This terminal is fuse (E0141) protected (250V,1A) for overload/short-circuit protection. The fuse is located at the bottom right of the control board.

Terminals T11 to T15 / Digital Inputs

The function of the digital inputs can be programmed from the keyboard, at the group G6 INPUT.

Terminals T16 and T17 / Motor PTC Input

If the PTC value is

≥1K7, a fault is generated and will be not reset until the resistance value is below

260 ohms. On the other hand, if this value is below 100ohm, a fault is also generated and will be not reset until the resistance value is

≥160ohms.

Terminals T18 to T21 / Analogue Inputs

The function of the Analogue inputs can be programmed from the keyboard at the group G6 Inputs.

To select 4-20mA or 0-10V you have to switch the jumpers as described below. See section ‘2.6

Considerations before Commissioning the SS7 Softstarters’ for further information:

Analogue Input 1 (T18-T19)

Position A1: 0-20mA / 4-20mA.

Position A2: 0-10V

Analogue Input 2 (T20-T21)

Position A3: 0-20mA / 4-20mA.

Position A4: 0-10V

Terminals T22 and T23 / Analogue Output

This Analogue output can have its format and source configured. Formats can be 0-10V, 0-20mA or

4-20mA. Configuration is done from group G7 OUTPUTS.

Terminal T25 / Analogue 0V connection

This terminal is 0V connection for analogue signals.

Terminals T26 to T30 / RS485/RS232

These terminals are provided for serial communications connection.

Serial communications are optically isolated from SS7 control electronics in order to increase the immunity from noise in hostile installation sites.

Function

The overload curve determines the response time under overload conditions.

There is a non-linear relation between the overload parameter (G3.2 OV

LOAD) and this parameter, in order to set the time required for tripping on F4

OVERLOAD. If 3 OV/LOAD T =1 is selected then the response time for an overload condition is almost immediate, but if OV/LOAD T=10 then takes the soft starter trips on F4 OVERLOAD after a time delay.

Adjust: If you need a fast response under overload conditions, please select

OV/LOAD T =1. If you need a slow response, then select OV/LOAD T =10.

For normal operation leave this value as default (OV/LOAD T =5).

The response time for the overload protection can be calculated from the following curve:

This parameter adjusts the OVERLOAD CURVE DURING ACCELERATION.

This parameter can be used to accelerate high inertia load. In case of pumps, fans (Torque = K x Speed^2) leave as default (100%).

This parameter is only active during acceleration and not at normal running conditions, where only

G3.2 & G3.3 are active.

Adjust: For low inertia applications like pumps, fans (Torque = K x Speed²) the default value (100%) active.

Mills, crushers and centrifuges (high inertia moment) will normally require a start with low starting overload factor (150%) and increase this value until the load accelerates without tripping on F4

OVERLOAD.

The soft starter allows the connection of a standard motor PTC

(Terminals T16-T17) to detect overheating of the motor. Every input resistance between 100ohm and 1.7kohms is taken as a correct value (OK) and every value found out of this range is taken as a fault

(FAULT). If the MOTOR PTC is set to “Yes” and the input resistance at terminals T16-T17 is out of the valid range, then the soft starter should trip on

F8 MOTOR PTC. To protect the motor after tripping due to PTC failure against further thermal overload, the PTC resistance must be less than 260 Ohms to reset the softstarter again. In case of a resistance below 100 Ohms the SS7 can be reset after the PTC has reached again a value of more than 160 Ohms.

Adjust: Depending on the availability of a valid Motor PTC, select Yes or No.

Under load current determines the current level the motor must not operate below.

Adjust: Usually leave as 50% of the nominal current of the motor

.

Applications: This protection helps to detect mechanical problems such as broken shafts, belts, ... when this occurs, the motor will run under no load conditions.

When working with pumps, this protection helps to detect no load pump operation, due to a lack of water or pump input pipe water position.

This parameter sets the maximum allowable operation time under load conditions before tripping.

Adjust: Depends on the application, but should be set to trip as soon as a condition occurs.

Applications: Pumps, fans.

Function

Establish the initial torque to be applied to the motor at the beginning of the ramp up.

Adjust: It is recommended to begin with a low initial torque value, normally default. Observe motor rotation immediately after start command. If the motor doesn’t spin, machine torque requirement may be higher, and it may be necessary to increase this until the motor starts to turn normal after a start command has been applied. If a very high current is noticed at the very beginning of starting process, this could be due to an initial torque setting that is too high - this must be decreased until a proper value is achieved.

Applications: For submerged pumps, generally a torque between 40% and

45% is required. For applications such as mills or crushers, the required torque is normally between 40% and 50%.

Note: These values are typical adjustments. Each application requires individual settings to achieve the best performance.

Set the time for 3 INITIAL TORQUE to be applied to the motor.

Adjust: When working with high inertia loads, increase this value in conjunction with parameter G4.4 INITIAL TORQUE, until the motor begins to turn. All other applications should leave this value as default.

Applications: In pumps a usual value is 0, and in heavy load machines it can vary between 1 and 3 seconds.

Adjusts the motor acceleration time from standstill to nominal speed, provided that no current limit occurs as that will cause a longer acceleration time.

Adjust: Depending on the application, the time set will vary in order to make sure no current limit takes place during acceleration. If this occurs, the acceleration time or acceleration current limit settings will need to be increased

Applications: In submerged pumps, the usual acceleration time is between 4 and 8 seconds. With very high inertial loads, that can vary between 20 and 60 seconds.

Note: These values are typical adjustments. Each application requires individual settings to achieve the best performance.

Maximum current a motor can draw during the acceleration/deceleration.

Adjust: Set the maximum current a motor can draw during the acceleration/deceleration of the motor. Typically set to 2.5 to 3x nominal current of the motor.

Values below 2 times of the motor rated current should be avoided. Under these conditions the resulting motor torque is normally insufficient to generate a successful start at full load; also the soft starter could trip on F4 Overload.

Function

Establish the initial torque to be applied to the motor at the beginning of the ramp up.

Adjust: Refer to parameter G4.4 for further information.

Set the time for the initial torque (G8.4) to be applied to the motor.

Adjust: Refer to parameter G4.5 for further information.

Adjust the motor acceleration time from standstill to nominal speed, provided that no current limit occurs as that will cause a longer acceleration time.

Adjust : The time setting depends on the application. Refer to parameter G4.6 for further information.

Maximum current a motor can draw during the acceleration/deceleration.

Adjust: Set to determine the maximum allowed current consumption during the acceleration/deceleration. Refer to parameter G4.7 for further information.

Set the required stop mode. The stop could be controlled through a ramp down voltage or uncontrolled where the time to stop depends on the inertia of the load (freewheel stop).

Adjust: If a controlled stop is required, set "N" for a spinning stop, set Y. Refer to parameter G5.1 for further information.

Establish the required time for a controlled stop.

Adjust: Begin with a short time and increase it until desired stop is achieved.

Refer to parameter G5.2 for further information.

In applications where it’s desired to avoid water hammer effect, select this algorithm. In other applications, the normal deceleration ramp is sufficient.

Adjust: In applications with water hammer problems during deceleration, select the hammer algorithm. In other applications set normal deceleration algorithm.

When selecting the hammer algorithm for the deceleration, 2 parameters must be set to properly adjust the stop.

Percentage of time the hammer algorithm is active during the deceleration time. Minimum torque the motor must deliver during the stop.

To correctly adjust the deceleration of such an application with hammer problems you may need to perform an interactive process by trial and error until the application is correctly commissioned.

Set the percentage of time for the hammer algorithm is to be active during deceleration.

Adjust: It is set in % of the deceleration time of the motor (G8.9).

Set the minimum torque to be applied during deceleration (for Hammer

Algorithm).

This parameter sets the correct phase sequence at the input, when starting the motor. It can happen that the soft starter tries to start with a phase sequence at the input different than the one we have set. In this case the soft starter trips on F2 WRONG PH/SQ.

Note: When operating at SLOW SPEED or DC BRAKE you must always select a phase sequence (L1 L2 L3 or Inverse Sequence). The option 1 NO

SEQ PROTECT is not allowed for these modes.

This parameter sets the overload motor current protection at nominal conditions. The time for this protection to trip depends on the actual current drawn by the motor and the parameter G3.3.

Adjust: Enter the rated (nameplate) motor current value.

This parameter sets the overload motor current protection at nominal conditions. The time for this protection to trip depends on the actual current drawn by the motor and the parameter G3.3.

This parameter adjusts the OVERLOAD CURVE DURING ACCELERATION.

Use this parameter when trying to accelerate high inertia load. In case of pumps, fans (Torque = K x Speed²) leave as default (100%).

This parameter is only active during acceleration and not in normal running conditions, where only G3.2 & G3.3 are active.

For low inertia pumps, fans (Torque = K x Speed²) leave as default value

(100%).

For mills, crushes and centrifuges (high inertia moment) start with low starting overload factor (150%) and increase this value till we can accelerate this load without tripping on F4 OVERLOAD.

The soft starter allows for the connection of a standard motor PTC (Terminals

T16-T17) to detect overheating of the motor. Every input resistance between

150ohm and 2.7kohms is taken as a correct value (ok) and every value found out of this range is taken as a fault (fault). If you select MOTOR PTC =Yes and the input resistance at terminals T16-T17 is out of the valid range, then the soft starter should trip on F8 MOTOR PTC. To protect the motor after tripping due to PTC alarm against further thermal overload, the PTC resistance.

Adjust: Depending on availability of a valid Motor PTC, select Yes or No.

Under load current determines the current level the motor must not operate below.

Adjust : Usually leave as 50% of the nominal current of the motor.

Applications: This protection helps to detect mechanical problems such as broken shafts, belts, ... when this occurs, the motor will running under no load conditions.

When working with pumps, this protection help to detect no load pump operation, due to a lack of water or pump input pipe water position.

This parameter sets the maximum allowable operation time under load conditions before tripping.

Adjust: Depends on the application, but should be set to trip as soon as a condition occurs.

Applications: Pumps, fans.

The soft starter should stop immediately when the current drawn by the motor reaches this value during nominal conditions. This parameter is off during acceleration or deceleration. The stop should be done in a controlled way.

Adjust: Set current value for the SS7 to stop.

Application: Oversized electrical motors used for starting, but working under nominal conditions at running, it may only reach the Shearpin current due to mechanical problems like locked rotors, etc.

Enable/Disable the asymmetric current protection at the soft starter. When enabled, the soft starter will trip on F3 ASYMMETRIC CURRENT if there is a current imbalance greater than 40%.

Enable/Disable DC brake. This option, will enable a continuous current to be applied for a determined torque (G13.2) and for a determined time

(G13.3).when the deceleration ramp is complete.

Applications: Ball mills, motor shaft positioning.

Note: high inertia applications, an external DC brake unit could be required.

Set the DC current to be applied to the motor. It must be considered that the brake energy dissipates entirely in the motor. A stop with high DC current or a stop that lasts for too long may cause overheating of the motor.

Adjust: It is sets in % of the achievable torque.

Sets the time for the DC current to be applied.

Adjust: The stopping rate of a motor using DC Brake current injection depends on the DC current applied (G13.2) for a preset time (G13.3).

The adjustments of these 2 variables and the inertia of the system will determine the deceleration time of the motor.

Applying an excessive brake current could cause overheating of the motor –

The same applies if the DC injection time is too long. However lower current or shorter time than necessary may not stop the motor as required

This Parameter sets the SS7 to work with an external brake unit. Relay 3 is dedicated to control the Brake Unit activation. See screen G7.3.

If the problem persists, call LS or an authorised distributor.

F4 OVER LOAD.

Action

Calculated motor overload has reached an unacceptable level.

Motor overload. If the trip is produced during start, it could be a mechanical problem. If it occurs when the motor is running at nominal speed, probable causes could be a wrong setting at G.3.2. screen or a change of the load conditions.

Wrong nameplate values.

Check that current from the G3.2 screen is the same as the motor. Check working conditions of motor. Check load. Check nameplates.

Fault
