ESD Guidelines

Caution

Electronic modules contain electrostatic sensitive devices that can be

destroyed easily, if they are handled incorrectly. However, if envisaged

manipulation does involve handling of such devices, the following in-

formation must be observed:

Electronics modules should not be touched unless work has to

be carried out on them.

If it is essential to touch an electronic module, the body must be

electro statically discharged beforehand.

Modules may not come into contact with electrically insulating

materials such as plastic foil, insulating table tops or clothing

made of synthetic fibers.

Modules may only be placed on electrically conducting surfaces.

Modules and electronic components should always be packed in

electrically conducting containers (such as metalized plastic

boxes or metal canisters) before being stored or shipped.

If packing containers are used, which are not conductive, mod-

ules and boards must be wrapped in a conducting material first.



Such materials are e.g. electrical conducting foam rubber or

household aluminium foil.

For easy reference, the protective measures necessary for handling

electrostatic sensitive devices are illustrated in the sketches below:

Starter Selection


2 Starter Selection

2.1 Starter Selection - Presentation

Principle description

ISA-HD is a highly sophisticated and reliable starter, designed for use

with standard medium voltage three-phase, squirrel cage induction

motors or synchronous motors. It provides the best method of reducing

current and torque during motor starting.The ISA-HD starts the motor

by supplying a slowly increasing voltage to the motor, providing soft

start and smooth acceleration, while drawing the minimum current

necessary to start the motor.The microprocessor based digital control

provides unique features like pump control, accurate motor protection

and optional analog output.The optional RS485 communication with

MODBUS, PROFIBUS and other (consult factory) protocols enables

full control (start, stop, dual adjust, command, etc.) and supervision.

Up to 32 starters or other MODBUS slaves can be connected via a

twisted shield pair to a host computer.

2.2 Motor current and starting conditions

Condition

Select the starter according to motor's Full Load Ampere (FLA) - as

indicated on its nameplate (even if the motor is not fully loaded) The

ISA-HD is designed to operate under the following conditions:

Max. ambient temp: 50°C

Max. starting current: 400 % motor's FLA

Max. starting time: 30 sec. (at 400 % FLA)

Max. starts per hour: 2 starts per hour at maximum conditions.

Starter Selection


2.3 Storage

The soft starter is designed for indoor use and must not be left out-

doors. Soft starter should be stored in a warm, dry room and protected

against dust and debris. If the soft starter is to be kept in store before

use make sure that the ambient conditions are acceptable:

Storing temperature: -20…..+70°C

Relative humidity: <95%, no condensation.

Attention

This statement only refers to standard cabinet!

For other than standard cabinet design refer to the supplied drawings

and/or consult the factory.

2.4 Temperature Range & Heat Dissipation

The ISA-HD is rated to operate within a temperature range of 0°C to

+ 50°C. Relative non-condensed humidity inside the enclosure must

not exceed 95%.

Attention

Operating the ISA-HD with a surrounding air temperature that is higher

than

50ºC will cause derating. Operating the ISA-HD with a surrounding air

temperature that is higher than 60ºC may cause damage to the ISA-

HD.

During soft start the maximum heat dissipation in Watts is as follows:

3.1 Prior to installation

Check

Check that motor full load ampere (FLA) is lower than or equal to the

starter full load current (FLC) and that the main and control voltages

are as indicated on the front panel.

3.2 Mounting

Attention

The starter must be mounted vertically. Allow sufficient space for

suitable airflow above and below the ISA-HD. Verify that mini-

mum clearances specified in the applicable codes/standards are

applied. In addition, when glass epoxy of any-type or thickness

is utilized within the cabinet assembly, minimum clearances

specified in the applicable codes/standards are not lowered.

Cabinet internal temperature should not exceed 50°C.

The starter should not be mounted close to heat sources.

The starter should be protected from dust and corrosive atmos-

phere.

Temperature range and relative humidity

The starter is rated to operate within the temperature range of -10°C

(14 F) to + 50°C (122 F).Relative humidity inside the enclosure should

not exceed 95 % non-condensing

Caution

Line and load connections may not be interchanged.

Installation


Short circuit protection

The starter must be protected against short circuit by MV fuses or Cir-

cuit Breaker in combination with a protection Relay. (For bigger cur-

rents >500A no MV Fuses are available)

Voltage transient protection

When high transients are expected, external protection should be used

(consult factory).

Danger

Power factor correction capacitors - if required - must be installed on

the line side of the ISA-HD.Do not connect three phase voltage without

starting the ISA-HD after less than 30 seconds!

3.3 Power section connections

Connection lines

Line to terminals L1, L2, and L3. Connection to mains voltage up to

15,000V. Thyristor’s PIV rating, internal circuitry and insulation defines

the following voltage levels:

2,300V +10%/ -15% 50/60Hz

4,160V +10% /-15% 50/60Hz

6,000V +10% /-15% 50/60Hz

6,600V +10% /-15% 50/60Hz

10,000V +10% / -15% 50/60Hz

11,000V +10% / -15% 50/60Hz

13,200V +10% / -15% 50/60Hz

13,800V +10% / -15% 50/60Hz

15,000V +10% / -15% 50/60Hz

Each ISA-HD is suitable for one of the above levels & for 50/60 Hz.

Installation


By-pass to terminals L1b, L2b, and L3b.

Preparation for bypass connection. Bypass preparation is standard in

all ISA-HD models up to 6.6kV. All ISA-HD models must be operated

with a Bypass Contactor. Bus bars and Bypass Contactor must be ar-

ranged to maintain current flow through the internal CTs after end of

the acceleration process. Otherwise, current protection of the soft

starter will not function.

Figure 2 Power section up to 6600V

This picture illustrates the Power Section of ISA-HD models up to

6.6kV.

ISA-HD models from 10kV and up have no preparation for bypass (by-

pass must be performed in the cabinet), CTs are mounted externally

to the Power Section and power supplies to the firing PCBs are

mounted externally to the Power Section.

Motor to U, V, and W.

Connection to motor

Note: Never connect power factor capacitors to soft starter output.

Power Factor capacitors, if required should be connected to the ISA-

HD line side (mains).

Installation


Line contactor and by-pass contactors must be used.

Do not connect any devices between the line contactor and the

ISA-HD.

Power factor capacitors, if required, should be installed on the

ISA-HD line side (not on the ISA-HD load side).

Mains supply must be applied in the correct phase sequence.

Interlock the line contactor - starting relay with the “fault relay” of

the ISA-HD.

Ground connection:

For proper operation and for safety reasons the ISA-HD Power Section

must be properly grounded.

Warning

When installing into a switch gear!

Do not perform “Hi-Pot” test on the switchgear after the soft-starter

has been installed in it. It may damage the ISA-HD.

4.2 Control Module

Control Module is the “brain” of the soft starter. It consists of the main

CPU PCB, fireboard PCB, power supply, optional PCBs (when or-

dered) and input/output interface terminals.

The Control Module for ISA-HD is identical for all ratings and suitable

for mounting in the L.V. compartment of the cabinet which should be

fully segregated from the M.V. compartment. Interposing relays should

be connected to all ISA-HD auxiliary contacts, three relays must be

incorporated: Immediate, End of Acceleration and Fault.

4.3 Memory system operation

Operating sequence

1. When control supply is switched on, the RAM is automatically

loaded from the Micro processor and parameters are displayed

on the LCD.

2. Parameters can now be modified via the keypad (if starter is in

one of the operating modes and software lock is open - DIP

switch 8 open).

Internal Settings


3. Start parameters can be modified during starting process and will

affect the operation immediately. Example: if current limit is set

too low and motor does not accelerate to full speed, increasing

the current limit setting will immediately affect the start process.

This enables selection of the optimal starting characteristics.

4.11 Special Control for Synchronous Motors

Excitation

The parameters TURN BYPAS ON AT and MIN TIME TO BYPAS are

used for special cases of synchronous motors excitation system.

These parameters are active only under the following conditions:

• Optional Relay PCB is installed

• When setting the RUN CONTACT DLY parameter, after reaching

120 seconds (maximum value) and operator keeps pressing for

additional 10 seconds the ▲ key.

The parameter TURN BYPASS ON AT determines motor current be-

low which the soft starter goes into Run condition and closes the End

Of Acceleration relay.

The parameter MIN TIME TO BYPS assures that Run condition cannot

be reached before the set time after the beginning of the starting pro-

cess.

This special feature is for synchronous motor starting applications

where the motor current at asynchronous speed may be at higher level

than regular asynchronous motor starting conditions. In this case the

level of current at which the Run condition is

Start and Stop Parameters


8 Start and Stop Parameters

8.1 Description of start curves

Start curves

Induction motors produce peak torque of up to 3 times the rated torque

towards the end of starting process. In some pump applications, this

peak may cause high pressure in the pipes.

The ISA-HD incorporates 5 different starting curves:

Start curve 0 - basic curve.

Start curve 1 - standard curve (default). The most stable and suitable

curve for the motor that prevents extended starting and motor over-

heating.

Pump control

Start curves 2, 3, 4 -

Pump Control - Induction motors produce peak torque of up to 3 times

the rated torque towards the end of starting process. In some pump

applications, this peak may cause pressure surge in the pipes. During

acceleration, before reaching peak torque, the Pump Control Program

automatically controls the voltage ramp-up, thus, reducing peak

torque.

Start Curve 5 - Torque curve. The most suitable curve for the motor

that provides linear acceleration and deceleration curves according to

the torque.

Figure 11 start curve 5, torque curve

Note

Consult factory for additional information

Note

Always start with start curve 1. If towards the end of acceleration, the

peak torque is too high (pressure is too high), proceed to curve 2 then

3 or 4 if necessary.

Pulse start

Sets PULSE LEVEL and PULSE START TIME. Intended to break free

high friction loads requiring high starting torque for a short time or for

pedestal start by holding the current at a predefined level for prede-

fined time period. The pulse is defined by its current level and time

length (width). After this pulse the voltage is ramped down to INITIAL

VOLTAGE setting before ramping up again to full voltage according to

the START PARAMETERS settings.



For PULSE TIME<1SEC. PULSE LEVEL can be set to 70-700% of

FLA; For PULSE TIME≥1SEC. PULSE LEVEL can be set to 70-400%

of FLA; In EXTENDED SETTING. PULSE LEVEL can be set to 70-

700% with the limitation of: 440 x (FLC/FLA).

Notes:

Note

• PULSE START is not effective in SOFT START CURVE 0.

For better control of the current withdrawn from the network (mainly

from generators), the following settings applies (applies from software

versions newer than MVSTMB.GN-010509):

Initial voltage

Determines the motor initial starting torque (the torque is directly pro-

portional to the square of the voltage).Range: 10 - 50 % UN (consult

factory for extended range) This adjustment also determines the in-

rush current and the resulting mechanical shock. A setting, which is

too high may cause high initial mechanical shock and high inrush cur-

rent (even if current limit is set low as the initial voltage setting over-

rides current limit setting).



A setting too low may result in prolonged time until motor begins to

turn. In general, this setting should ensure that the motor begins turn-

ing immediately after start signal.

Figure 13 initial voltage

Note:

When INITIAL VOLTAGE is set its maximum value, this displays

changes to INITIAL CURRENT. When INITIAL CURRENT is set the

ISA-HD causes current ramp instead of voltage ramp.

Current limit

Determines the motor highest current during starting.

Range 100 - 400 % of FLA setting (consult factory for extended range).

A too high setting will cause higher current drawn from the mains and

faster acceleration. A setting too low may prevent motor from complet-

ing acceleration process and reaching full speed.

In general, this setting should be set to a value high enough to prevent

stalling.

Note

Current limit is not operating during RUN and SOFT STOP.

Range 1 - 30 sec. (consult factory for extended range). It is recom-

mended to set acceleration time to the minimum acceptable value (ap-

prox. 5 sec).

Figure 15 acceleration time

Note

1. Since current limit overrides acceleration time when current limit is

set low, starting time will be longer than the preset acceleration

time.

2. When motor reaches full speed before voltage has reached nomi-

nal voltage, acceleration time setting is overridden and causes the

voltage to ramp-up quickly to nominal.

Maximum start time

The maximum allowable starts time from start signal to the end of ac-

celeration. If voltage does not reach full voltage during this time (for

example, because of low current limit setting), the starter will trip the

motor. LCD displays “Long Start Time” message.

Range: 1 - 30 sec (consult factory for extended range).

Number of starts

Sets NUMBER OF STARTS permitted during STARTS PERIOD.

Limits the number of starts during the period of time defined by

STARTS PERIOD.

If you try to start even one more time within that period the START

INHIBIT period will take effect.

counted.

the ▲ key and only if optional Relay PCB is installed the display

changes to: TURN BYPASS ON AT 120-300%.

Sets time delay for End of Acceleration relay to close after completion

of starting process. End of Acceleration relay can signal that motor is

at its RUN position which can be used for motor loading.



8.2 Description of stop curves

Pump control - stop curve

Intended to prevent water hammer during stopping. In pump applica-

tions, load torque decreases in square relation to the speed and re-

ducing the voltage will reduce torque so motor will smoothly decelerate

to stop.SOFT STOP initiation opens the End of Acceleration contact

and opens the Bypass Contactor. Load will be transferred to the ISA-

HD thyristors and voltage begins to ramp down. The ISA-HD incorpo-

rates 5 stopping curves that enable you to select the suitable torque

curve:

The following stop curves can be selected:

Stop curve 0 - basic curve.

Stop curve 1 - Standard default curve - voltage is linearly reduced

from nominal to zero. The most stable and suitable curve for prevent-

ing prolonged stopping and motor overheating.

Stop curves 2, 3, 4 - In some pump applications, when pumping to

higher elevation a considerable part of the torque is constant and does

not decrease with speed. It may happen that during the deceleration

process when voltage decreases the motor torque abruptly falls below

load torque (instead of smoothly decreasing speed to zero), thus clos-

ing the valve and causing water hammer. Curves 2, 3 and 4 eliminate

the water hammer phenomenon. In pump application the load torque

decreases in square relation to the speed, thus correcting control of

voltage to reduce torque adequately and to smooth deceleration to a

stop.

It is recommended that SOFT STOP CURVE 1 be used for all standard

applications (not pumps).

To reduce water hammer, select SOFT STOP CURVE 2, then 3, then

4 in that order. Curves 2, 3, 4 designed to prevent stall condition..

Stop curve 5 (Torque curve) - Provides linear deceleration of the

torque. In certain loads, linear torque deceleration can result in close

to linear speed deceleration, thus eliminating stall conditions.

tended range).

Note

Soft stop initiation opens the END OF ACCELERATION contact and

opens the by-pass contactor. Load will be transferred to the ISA-HD

and voltage begins to ramp down.

LONG START TIME - (stall protection)

Trips the starter if the motor does not reach full speed during “MAXI-

MUM START TIME”.

Range: 1 - 30 sec. (consult factory for extended range).

Over Current Shear-pin trip

Operational when starter is energized and has two functions:

Trips the starter when current exceeds 850 % of starter's FLC

setting in 1 cycle or less.

850 % FLA with delay during start (850 % overrides O\L settings).

During run (after RUN LED is on) it trips the starter if current ex-

ceeds set level and time delay.

Range: 100 - 850 % of motor FLA setting

Delay: 0 - 5 sec. (0 = up to 200 msec)

Note

The O/C shear-pin trip is not intended to replace the fast acting fused.

Overload (O/L)

Sets OVERLOAD CLASS characteristics Sets OVERLOAD PRO-

TECT functionality. The ISA-HD allows motor protection according to

IEC class 5, 10, 15, 20, 25 or 30 or according to NEMA class 5, 10,

15, 20, 25 or 30. Tripping curves are shown on section 4.8 and 4.9.

The OVERLOAD protection incorporates a THERMAL CAPACITY

register that calculates heating minus dissipation of the motor. The



ISA-HD trips when the register fills up. (THERMAL CAPACITY=100%)

The time constant, in seconds, for cool down after overload trip is:

Class 5 10 15 20 25 30

IEC 160 320 480 640 510 960

NEMA 140 280 420 560 700 840

The overload protection can be set to protect the motor as set in the

OVERLOAD PROTECT parameter:

ENABLE – motor is protected at all time.

ENABLE WHILE RUN – motor is protected only when in Run.

DISABLE – motor is not overload protected by the soft starter.

Note:

In order to restart after OVERLOAD trip, the thermal register should

be 50% or less.

Under Current

Operational when motor is running. Trips the starter when motor cur-

rent drops below under current trip (UCT) set point for a period of time

longer than under current delay (UCD).

Under current trip range: 0 = Off, 20 - 90 % of FLA

Under current delay range: 1 - 40 sec.

Auto Reset

A special feature enables auto reset after an adjustable time delay.

Range: Off, 10 - 120 min.

Under Voltage / No Voltage

Operational after start signal. It trips the starter when main voltage

drops below the under voltage trip set point for a period of time longer



than under voltage delay. Auto reset can be activated via fault param-

eters. Auto reset is activated 60 sec after trip occurred.

Under voltage trip range: 70 - 90 % UN (phase to phase)

Under voltage delay range: 1 - 10 sec.

Note

1. When voltage drops to zero (voltage outage) the starter will trip im-

mediately, overriding the delay.

2. Auto reset cannot be activated if start signal is still connected.

Over Voltage

Operational after start signal. It trips the starter when main voltage ex-

ceeds the over voltage trip set point for an adjustable period of time

longer than over voltage delay.

Range: 110 - 125% of UN (phase to phase)

Over voltage delay range: 1 - 10 sec.

Phase loss (with programmable auto reset)

Operational when starter is energized and protects motor from loss of

phase.

It trips the starter when one or two phases are missing. Auto reset can

be activated via fault parameters. Auto reset is activated 60 sec after

trip occurred.

Note

3. Phase loss might not be detected for lightly loaded motors.

4. Auto reset cannot be activated if start signal is still connected.



Phase Sequence

It trips the starter when starter is energized and phase sequence is

wrong.

Heat-sink Over Temperature

Thermal sensors are mounted on the heat-sinks and trip the starter

when temperature exceeds 85°C.

External fault 1 and 2

Operational when starter is energized. It trips the starter when an ex-

ternal contact closes for more than 2 sec.

Unbalance Current Trip

Operational after start signal. It trips the starter when current unbal-

ance increases above the preset “UNBALANCE TRIP” for more than

the “UNBALANCE DLY” set-point.

Range: 10 - 100 %. Delay: 1 - 60 sec.

Ground Fault Trip

Operational after start signal. It trips the starter when ground current

increases above the preset “GND FAULT TRIP” for more than “GND

FAULT DLY” set point.

Range: 10 - 100 %. Delay: 1 - 60 sec.

Set to curve 0

Trip occurs if the Soft Starter starts with a non-adequate starting

curve to the network.

Motor insulation

(Optional) Trips the ISA-HD when the motor insulation level decreases

below the trip level set..

Power ON and No start



Operational upon main voltage connection. It trips the motor when

main voltage is connected to the ISA-HD for more than 30 sec. without

a start signal.

Modbus Time out

If no valid Modbus communication during MODBUS TIME OUT, the

ISA-HD will trip. Trip occurs only if the following conditions exist:

• SER. LINK CONTROL is set to ENABLE

• SERIAL LINK NO. is not set to OFF

By-pass Open

If the by-pass is located in a separate cabinet and after by-pass is

closed, current measurement reads “0” the soft starter trips and dis-

plays “BP TRIP”. It is possible to disable this protection by setting BP

open trip to disable (on fault setting page).

Note

Most of the protections after BYPASS IS CLOSED can be disable by

respective settings on the fault page

Non Adjustable Protection Functions

UNDER / OVER FREQEUNCY

Trips the ISA-HD if frequency is not in the range of 44-65Hz

Check that frequency variations are between 44-65Hz.

PHASELOSS

Trips the starter if 1 or 2 phases are missing.

Check lines voltages and correct connection.



WRONG PARAMETER

After power up parameters not transferred from RAM to EEPROM or

vice versa. Press Reset then load DEFAULT PARAMETERS. Refer to

section 10 for more details on loading default parameters. Note that

obtaining DEFAULT PARAMETERS erases all previously modified

settings and requires the operator to reprogram all parameters that

differ from the factory default.

Note:

It is especially important to reprogram the RATED LINE VOLTAGE

and STARTER FLC (as shown on the label of the ISA-HD) and all

other parameters in the MAIN & PROTECT mod page.

Wrong Connections and Shorted SCR

Operational after start signal. It trips the starter if motor is not properly

connected to starter's load terminals, or if:

• Internal disconnection in the motor winding is detected.

• one or more SCRs are shorted.

• a fiber - optic lead is not properly inserted.

This protection is not active when SOFT START CURVE 0 is selected.

Check with an ohmmeter between L1-U, L2-V, L3-W; resistances are

listed on section xxx..

Check for no voltage on terminals U, V, W (from parallel system or an

independent bypass).

OVERTEMPERATURE

Thermal sensors are mounted on the heat-sinks of the Power Section

and trip the ISA-HD when the temperature rises above 85ºC.



Caution

The over temperature protection is designed to operate under normal

conditions e.g. in the event of extended low overload.

Incorrect starter selection or operations frequent starting at maximum

conditions or repeated starting under fault conditions can cause SCRs

to overheat and fail before the heat-sink reaches 85°C to trip the ther-

mal sensors.

STORAGE ERROR

When trying to store parameters at the end of a mode page or after

Trips the ISA-HD if, when controlled via Profibus communication link,

the communication cable is torn or the communication from the PLC

is lost.

Note that the occurrence of this fault depends on then “Watch Dog”

function of the Profibus controller. You must reconnect the wiring

and/or the communication with the PLC and wait for a start command

initiated by the PLC. Trips the ISA-HD if, when controlled via Profibus

communication link, the communication cable is torn or the communi-

cation from the PLC is lost.

Note that the occurrence of this fault depends on then “Watch Dog”

function of the Profibus controller. You must reconnect the wiring

and/or the communication with the PLC and wait for a start command

initiated by the PLC.



Fault and reset

When any of the above protection operates, the starter locks in a fault

condition and disables thyristors firing.

Fault LED turns ON, fault description is displayed on the LCD and fault

relay operates.

• For local resetting, after fault has been removed, press <RE-

SET> key.

• Remote resetting can be done through terminals 7 or 8 (refer to

I/O programming ).

When a fault occurs followed by a voltage outage, fault condition is

latched and re-appears upon voltage restoration.

Note

Resetting is not possible when a start command is active.

Auto reset under voltage and phase loss

Under-voltage and phase-loss faults can be set to Auto-Reset (see

fault parameters). The starter will reset itself 60 sec after the trip, pro-

vided that no start signal is active.

Auto reset under -current

Under-current fault can be set to Auto-reset (see fault parameters).

The starter will reset itself after the adjustable “UNDER CUR. RESET”

provided that no start signal is active.

Press ▲ or ▼ keys to set Initial CURRENT.

Range: 100 - 500 % of UN. (only when use)

INITIAL CURRENT

100%

Description: Sets motor’s INITIAL STARTING VOLTAGE. The motor’s torque is di-rectly proportional to the square of the voltage. This adjustment also determines the inrush current and mechanical shock. A setting that is too high may cause high initial mechanical shock and high inrush current. This can

occur even if CURRENT LIMIT is set low because the INITIAL VOLTAGE setting overrides the CURRENT LIMIT setting. A setting that is too low may result in pro-longed time until the motor starts to turn. In general, this setting should ensure that the motor starts turning immediately after start signal.

Parameter Setting


Instruction Display

Note:

When INITIAL VOLTAGE is set its maximum value, this displays changes to INI-TIAL CURRENT.

When INITIAL CURRENT is set the ISA-HD causes current ramp instead of volt-age ramp.

Press <SELCET>

Press ▲ or ▼ keys to set current limit.

Range: 100 - 400 % of motor FLA. (extended settings 100-700%)

CURRENT LIMIT 400 % OF FLA

Description: Sets motor’s CURRENT LIMIT during starting. A setting that is too high will increase the current drawn from mains and faster acceleration. A setting that is too low may prevent the motor from completing acceleration process and reaching full speed. In general, this setting should be set to a value that is high enough to prevent stalling.

Note: CURRENT LIMIT does not operate during RUN and SOFT STOP.

Press <SELCET>

Press ▲ or ▼ keys to set acceleration time.

Range: 1 - 30 sec.

ACC. TIME 10 SEC.

Description: Sets ACCELERATION TIME of the motor. Determines the motor’s voltage ramp-up time, from initial to full voltage. It is recommended to set ACCEL-ERATION TIME to the minimum acceptable value (approx. 5 sec).

Notes:

• Since CURRENT LIMIT overrides ACC. TIME, when CURRENT LIMIT is set low, the starting time will be longer than the ACC. TIME setting.

• When the motor reaches full speed before voltage reaches nominal, ACC. TIME setting is overridden, causing voltage to quickly ramp-up to nominal.

• Using starting curves 2, 3, 4 prevents quick ramp up.
