Starter Selection

The RVS-DN is a highly sophisticated and reliable starter designed for use with standard three-phase, three-wire, squirrel cage induction motors. It provides the best method of reducing current and torque during motor starting.

The RVS-DN 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 second generation, microprocessor based digital circuitry provides unique features like pump control, slow speed, electronic reversing and accurate motor protection, with optional Insulation Protection, Thermistor input, etc.

The optional RS 485 Communication with MODBUS protocol enables full control (Start, Stop, Dual Adjust, command, etc.) and supervision. Up to 32 starters can be connected on a shield twisted pair to a host computer.

The starter should be selected in accordance with the following criteria (see Ordering Information data).

Motor Current & Starting Conditions

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 RVS-DN is designed to operate under the following conditions:

Max. ambient temp: 50ºC Max. starting current: 400% motor’s FLA Max. starting time: 30 sec. (at 400% FLA) Max. starts per hour: 4 starts per hour at max conditions. Up to 60 starts per hour at light load applications.

Note: For very frequent starts (inching applications),

the inching current should be considered as the Full Load Ampere (FLA).

Main Voltage (line to line) Thyristor’s PIV rating, internal circuitry and insulation defines four voltage levels: 220-440V, 575-600V 460-500V, 660-690V Each starter is suitable for one of the above levels & for 50/60 Hz.

Control Voltage The Control Voltage operates the electronic circuitry and fans. Two voltage levels are available:

220-240V + 10%-15%, 50/60 Hz (standard) 110-120V + 10%-15%, 50/60 Hz 110 Vdc for Frame size B-G (by special order).

Control Inputs

Control Input voltage (start, stop, etc.) can be the same as Control Supply above (standard), or 24-240V AC / DC (by special order).

Installation

Prior to Installation

Check that Motor’s Full Load Ampere (FLA) is lower than or equal to the starters Full Load Current (FLC) and that Main and Control voltages are as indicated on the front panel.

Mounting

• The starter must be mounted vertically, allow sufficient space above and below the starter for suitable airflow.

• It is recommended to mount the starter directly on the rear metal plate for better heat dissipation.

• Do not mount the starter near heat sources.

• Protect the starter from dust and corrosive

atmospheres.

Note: For harsh environments, it is recommended to order the starter with Option # 8 – Special Treatment (printed circuit board coating).

Temp. Range and Heat Dissipation The starter is rated to operate over a temperature range of -10ºC (14ºF) to + 50ºC (122ºF). Relative noncondensed humidity inside the enclosure should not exceed 95%.

Starter’s heat dissipation is approx. 3 x In (three times the current in watts).

Example: For a 100A motor, heat dissipation is approx. 300 watts. Internal enclosure heating can be reduced through the use of: a. Additional ventilation b. Employing a by-pass contactor.

) - Surface area that can dissipate heat

(front, sides, top).

* Total heat dissipation of the starter and other control devices in the enclosure.

Note: If the starter is installed in a non-metallic enclosure, a by-pass contactor must be used.

Short Circuit Protection

Protect the starter against a short circuit by Thyristor Protection Fuses (see appendix page 44 for I

t and

fuses).

Transient Protection

Line transient voltages can cause a malfunction of the starter and damage to the thyristors. Starters frame sizes B-E incorporate Metal Oxide Varistors (MOV to protect from normal line voltage spikes.

For size A, or when higher transients are expected, additional external protection should be used (consult factory).

ATTENTION

When Start signal is initiated and a motor is not connected to load terminals, the Wrong Connection protection will be activated.

WARNING

1. When main voltage is connected to the RVS-DN, even if control voltage is disconnected, full voltage may appear on the starter load terminals. Therefore, for isolation purposes, it is necessary to connect an isolating device before the starter.

2. Power factor correction capacitors must not be installed on the starters load side. When required, install capacitors on starter’s line side.

WARNING

RVS-DN current transformers, although may be installed outside of the soft-starter with extended wires, can not be grounded or connected to any other load except for the RVS-DN itself. Any such connection may cause damage to the load which was connected to it or to the RVS-DN itself!

By-pass Contactor

Under normal operating conditions, the heat dissipated by an electronic soft starter causes heating of the enclosure and energy losses. The heating and losses can be eliminated by the use of a by-pass contactor, which by passes the RVS-DN after completion of startup, so motor current will flow through the by-pass contactor.

In this case the starter protection will be maintained except for the current protection, as the current

RVS-DN

will not flow through the internal current transformers after the bypass closes.

Preparation for By-pass Contactor (option)

In order to maintain current protection after the by-pass contactor closes, Preparations for By-pass Contactor can be ordered.

1. It is recommended that terminals 1-3 be always connected to Control Supply.

2. In some applications, it is required to open the upstream contactor after soft stopping. The upstream contactor can be operated by the Immediate Contact that changes its position only at the end of soft stop.

It is therefore recommended to delay the opening of the upstream contactor for a few seconds after the completion of Soft stop process, when current reached zero, see Immediate/Shear-pin Contact delay – page 7.

Ensure that auxiliary contact C

•

closes after

the main contactor “the soft-starter provides a 500 mSec. delay for the start signal. If it closes before, Under Voltage, fault will occur. It is recommended to use a time delay timer to prevent possible faults.

End of Acceleration contact is activated after an adjustable time delays “Run Contact Delay” – see page 29 at the end of start-up period, closing the by-pass contactor.

The contact will return to its original position when:

• Soft Stop or Stop signals are initiated

• Energy Saver signal is initiated

• Slow-Speed signal is initiated

• Fault condition occurs.

When the by-pass contactor closes, current to the motor will flow through the by-pass.

Note: When a by-pass contactor is used, it is

recommended to order the starter with preparation for by-pass contactor, so that the RVS-DN current protections are operative also after the by-pass contactor closes.

When a Soft Stop signal is given, the End of Acceleration contact returns to its original position opening the by-pass contactor. Thereafter, the voltage will gradually ramp down to zero, soft stopping the motor.

High Speed

Used for Two Speed Motors:

* When soft start is required during transfer from low to high speed, the RVS-DN should be installed downstream to the high speed contactor (marked 1) and operated by its auxiliary contact (13-14).

* When soft start is required for both low and high speeds, the RVS-DN should be mounted before both contactors (marked 2) and operated by each of the downstream contactors (13-14 of each contactor).

Note: The RVS-DN should be sized for

appropriate motor rating of either the low or the high speed.

If two different motor ratings and/or starting characteristics are required, for example, higher Initial Voltage and Current Limit for high speed, use the Dual Adjustment feature (see Dual Adjustment – page 21) which allows two different settings of:

* Initial Voltage * Current Limit * Acceleration Time * Deceleration Time * Motor FLA.

An additional N.O. contact (15-16) on the high-speed contactor should act as the Dual Adjustment Switch. It should close simultaneously with 13-14 of the same contactor to start the RVS-DN and to switch to the Dual Adjustment settings.

1. When starting from a Diesel-Gen., its voltage regulator (especially older type regulators) may be affected during the starting process, causing rapid voltage fluctuations (~350V to ~500V in 400V systems). In these rare cases, the voltage regulator must be upgraded – consult your Diesel-Gen. Supplier.

2. In most other cases where voltage, current or frequency is unstable – a special routine may be applied to overcome the starting difficulty. Use the procedure below:-

a. Set Dip. Switch # 3 to “On” (as shown above). b. Insert a contact (or jumper) between Control Supply and terminal 8 (Dual Adjust. Terminal) and close contact to

operate the Generator Mode. Dual Adjust LED will light when operating in Generator Mode.

c. Set Dual Adjust parameters to the values necessary for the application (e.g. faster acceleration, lower current limit,

etc.).

3. When operating from Main and alternatively from Diesel Gen. Set normal starting characteristics for Main and suitable parameters for the Diesel Gen. in the Dual Adjustment setting. When starting from Main, the primary settings (suitable for main starting) will be operative. Upon starting from Generator, close contact between Control Supply and Terminal 8 to operate on Generator Mode.

Note: Ensure that Diesel Gen. size is suitable (Diesel Gen. KVA should be at least is 1.35 motor KVA, consult

factory for all other cases).

WARNING

1. Motor can not run idle and must be loaded when operating in Generator Mode, otherwise vibration may occur during starting and stopping.

2. When using extended range, use maximum precaution to avoid motor or starter burnout.

3. Disconnect all other loads before starting for the first time to prevent damages due to voltage fluctuations.

4. Disconnect Power Factor Capacitors when operating with Diesel Gen.

5. Connect terminal 21 to terminals 3 and/or 9 only if these terminals are connected to neutral or at ground potential.

6. Only potential free contacts may be connected to terminal 21. Do not connect any voltage to terminal 21. Any connection of voltage to this terminal may disrupt soft-starter operation, and cause starter or motor damage.

The RVS-DN incorporates 3 memory systems:

EPROM A read-only, non-volatile memory, containing factory set parameters (default) that cannot be changed.

EEPROM

A read/write, non-volatile memory, where field adjusted parameters, statistical and fault data are saved and stored.

RAM A read/write memory containing parameters loaded from the EEPROM which can be changed from the keypad. These parameters are stored only as long as Control Supply is connected.

Memory system operation

1. When Control Supply is switched on, the RAM is automatically loaded from the EEPROM and parameters are displayed on the LCD.

2. Parameters can now be modified from the keypad (if starter is in one of the operating modes and software lock is open – Dip Sw. 8 open).

3. Start Parameters can be modified during starting process and will immediately affect the operation. For example, if Current Limit is set too low and motor does not accelerate to full speed, increasing Current Limit setting will immediately affect starting process. This enables selection of the optimal starting characteristics. After completion of the adjustments, parameters should be stored in the EEPROM. Storing new parameters is possible at the end of each Mode Page by pressing Store key after “Store Enable” is displayed on the LCD.

Internal Settings

Inside Delta Motor Connection Mode

Allows connection of the RVS-DN inside the Delta. Current is reduced by 1.73 (3), namely for an 800A motor the standard selection will be an 820A softstarter. “In the Delta”, the calculation will be 800 / 1.73 = 460A, hence, for a 800A motor, a 460A “Inside Delta” starter is selected. Programming via first window in “Main Parameters”. Selectable options are: either “Line” or “Inside Delta”. See Appendix for “Inside Delta” details and motor connection diagram.

Dip Switch settings The Dip Switch, containing eight separate switches, is located under the front cover of Control Module (in sizes B-F) and under the Display unit (in size A). When necessary, carefully open the front panel and set the switches as required.

Start & Stop Parameters

Pump Control – 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 RVS-DN incorporates 4 different starting curves:

Start Curve 0 – Standard curve (Default). The most stable and suitable curve for the motor, preventing prolonged starting and motor overheating.

Start Curves 1, 2, 3 – During acceleration, before reaching peak torque, the Pump Control Program automatically controls the voltage ramp-up, reducing peak torque.

information.

Pulse Start

Intended to start high friction loads, requiring high starting torque for a short time. A pulse of approx. 80% Un without Current Limit is initiated to break the load frees. Pulse duration is adjustable, 0.1 – 1 sec.

After this pulse, the voltage is ramped down to Initial Voltage setting, before ramping up again to full voltage according to Start Parameters settings.

Initial Voltage

Determines motor’s initial starting torque (the torque is directly proportional to the square of the voltage). Range: 10-50% Un (consult factory for extended range). 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 (even if Current Limit is set low, as the

Initial Voltage setting overrides Current Limit setting).

A setting that is too low may result in prolonged time until motor

100%

begins to turn. In general, this setting should ensure that the motor begins turning immediately

after

start signal.

50%

10%

Current Ramp (Initial Current)

Determines initial Ramp-Up starting Current. When desired, increase Initial Voltage to Max. (50% or 80% respectively). The LCD displays “Initial Current” and the starter will linearly Ramp Up the current following the desired acceleration time. Range: 100-400%

Current limit

Determines motor’s highest current during starting. Range 100-400% of FLA setting (consult factory for extended range). A too high setting will cause greater current drawn from main and faster acceleration.

A setting that is too low may prevent motor from completing acceleration process and reaching full speed. In general, this setting

400%

should be set to a high enough value in order to prevent stalling.

100%

Note: Current limit is not operating during Run and Soft stop.

Acceleration Time

Determines motor’s voltage rampup time, from initial to full voltage.

100%

Range 1-30 sec. (consult factory for extended range). It is recommended to set Acceleration Time to the minimum acceptable value (approx.

5 sec).

30 sec

Notes:

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

reaches nominal, Acceleration Time setting is overridden, causing voltage to quickly rampup to nominal.

3. Using starting curves 1, 2, 3 prevents quick

ramp up.

Start & Stop Parameters

Maximum Start Time

The maximum allowable starts time, from start signal to end of acceleration. 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).

Contact Delay

Time delay for End of Acceleration Contact, after completion of starting process. Range: 0-120 sec.

Pump Control – Stop curve

Intended to prevent Water Hammer during stopping. In pump applications, load torque decreases in square relation to the speed, thus, reducing the voltage will reduce torque and motor will smoothly decelerate to a stop.

The following Stop curves can be selected:

Stop curves 0 – Standard Default curve – voltage is linearly reduced from nominal to zero.

Stop curves 1, 2, 3 –

In some pump applications, when pumping to a higher level, a considerable part of the torque is constant and does not decrease with speed. It may happen that during Soft Stop, when voltage is decreasing, motor torque quickly falls below load torque and motor will abruptly stall instead of smoothly decreasing speed to zero.

Stop Curve 4 (Torque) – Provides Linear Controlled torque deceleration ramp, from Ta (Actual Torque), thus, eliminating stall conditions.

Always use Stop Curve 0. If motor stalls

Note:

quickly instead of slowly decreasing its speed, select Stop Curve 1, 2, 3 or 4 if necessary.

Deceleration Time – Soft Stop

100%

urves 1, 2, 3 designed to prevent tall condition

Note: When the starter operates with a by-pass contactor, Soft Stop initiation opens the End Of Acceleration contact, tripping open the by-pass contactor. Load will then be transferred to the RVSDN and voltage begins ramping down.

Slow Speed Torque

Determines the torque while motor is operating at 1/6 of nominal speed. Range: 1-10.

Maximum Slow Speed Time

Determines the maximum allowable operation time at slow speed. Range: 1-30 sec. (consult factory for extended range).

WARNING

Operating current while motor is running at 1/6 speed

is much higher than nominal current and motor

ventilation is much weaker. Special precaution must

be taken to prevent overheating when running the

motor at slow speed for long periods of time.

Motor & Starter Protection

Motor Insulation (option)

Operational when motor is not running (the motor must be galvanically isolated). Two distinct level can be set for Alarm and Trip functions.

• Alarm level, Range: 0.2 – 5 M

• Trip level, Range : 0.2 – 5 M

When insulation decreases below Alarm Level set point for more than 120 sec., the LCD displays ALARM: INSULATION LEVEL and shows the value in M. The Fault LED flashes and the Insulation Alarm Relay is activated. Alarm signal will disappear automatically 60 seconds after insulation level returns to normal. Trip does not reset automatically.

When insulation decreases below Trip Level set point, the LCD displays TRIP: INSULATION LEVEL and shows the value in Mohm. The fault LED illuminates and Fault Relay is activated.

Motor Thermistor (option – Analogue Card)

Measures motor’s thermistor resistance and trips the starter when level decreases below set level. Only one of the optional cards can be fitted in one starter, Analogue card or Insulation card. Thermistor Type: Selectable PTC or NTC. Trip Level, range: 1 – 10 K Delay: Factory preset time delay of 2 sec.

Too Many Starts

Combines three parameters:

• Number of Starts Determines maximum allowable number of starts. Range: Off, 1-10 starts.

• Start Period

Time period during which Number of Starts is being counted. Range: 1-60 min.

• Start inhibit

Determines time period during which starting is disabled after “Too many starts” trip. Range: 1-60 min

Note: Motor can not be started before “Start

Inhibit Time” has elapsed. Trying to start the motor during this time delay will result in LCD displaying “Wait Before Rst: ___ MIN.

Long Start Time – (Stall Protection) Trips the starter if motor does not reach full speed during “Maximum Start Time”. Range: 1-30 sec. (consult factory for extended range).

Over Current Shear-pin

Becomes operational when starter is energized and has two Trip functions:

• Trips the starter when current exceeds 850% of starter’s FLC setting in 1 cycle or less.

• During run (after RUN LED is lit) – Trips the starter when current exceeds set level and time delay.

Range: 200 - 850% of motor FLA setting Delay: 0 – 5 sec. (0=up to 200 mSec)

Note: The O/C Shear-Pin is not intended to replace the

fast acting fuses, required to protect the thyristors (see fuse table in the appendix).

Overload (O/L)

Inverse time electronic overload becomes operational when RUN LED is lit.

The O/L circuitry incorporates a Thermal Memory Register calculating heating minus

dissipation of the motor. The starter trips when the register fills up. The thermal register resets itself 15 minutes after

500115

motor stops.

Adjustable between 75-150% of motor’s FLA and factory set at 115%. Tripping time at 500% FLA is adjustable between 1-10 sec. Allowing trip curve selection.

ATTENTION

Overload protection is not operative during soft-start or soft stop.

Under Current

Operational when motor is running. Trips the starter when motor current drops below set Under Current Trip (UCT) for a time longer than Under Current Delay (UCD). Under Current Trip, Range: 0=Off, 20-90% of FLA Under Current Delay. Range: 1-40 sec.

Under Voltage

Becomes operational only after start signal. Trips the starter when main voltage drops below the set Under Voltage Trip (UVT) for a time longer than Under Voltage Delay (UVD). Under Voltage Trip, Range: 120-600V (phase to phase) Under Voltage delay, range 1-10 sec.

Note:

When voltage drops to zero (full voltage outage) the starter will trip immediately, overriding the delay.

Motor & Starter Protection

Over Voltage

Becomes operational only after start signal. Trips the starter when main voltage increases above the set Over Voltage Trip (OVT) Level for an adjustable period of time longer than Over Voltage Delay (OVD). Range: 150 – 750V (phase to phase) Over Voltage Delay, Range: 1-10 sec.

Phase loss (and Under / Over Frequency)

Becomes operational when starter is energized and protects motor from single phasing. Trips the starter when 1 or 2 phases are missing for more than 1 sec.

Starter will also trip when frequency is less than 40 or greater than 65Hz.

Note: Phase loss might not be detected in

lightly loaded motors.

Phase Sequence

Becomes operational when starter is energized, provided this protection has been activated (Fault Enable – Phase Sequence Protection, see Fault Parameters). Trips the starter when phase sequence is wrong.

Long Slow-Speed Time Trips the starter if motor operates at slow speed for a time longer than “Maximum Slow Speed Time” Range: 1-30 sec. (consult factory for extended range).

Note: Operate motor at slow speed for the

minimum possible time to prevent overheating. When motor operates at slow speed, it draws higher than nominal current (depending on Slow-Speed Torque adjustment) thus, motor and starter may overheat.

Wrong Connections

Become operational after start signal. Trips if motor is not properly connected to starter’s Load terminals, or when: Internal disconnection in the motor winding is detected.

Shorted SCR

Trips the starter in case one or more SCRs have been shorted.

Heatsink Over Temperature

Thermal sensors are mounted on the heatsink and trip the starter when temperature rises above 85ºC.

WARNING

The over temperature protection is designed to operate under normal conditions e.g. in the event of extended low overload, insufficient ventilation – fan stoppage or air flow blockage. Incorrect starter selection or operation frequents starting at max. conditions, or repeated starting under fault conditions can cause SCRs to overheat and fail

the heatsink reaches 85°C to trip the thermal

before sensors.

External Fault

Becomes operational when starter is energized, trips the starter when an External Contact closes for more than 2 sec.

WARNING

Do not use External Fault when terminal 21 is not connected to ground.

Fault and Reset

When any of the above protection (except Insulation Alarm) operates, the starter locks in a fault condition, disabling thyristors firing. Fault LED lights up, fault description is displayed on the LCD and Fault Relay operates.

• For local resetting, after fault has been

removed, press Reset key.

• Remote resetting can be done through

terminals 7 or 8 (see I/O Programming).

When Fault occurs, followed by a voltage outage, fault condition is latched and reappears upon voltage restoration.

Note: Resetting is not possible

Auto Reset

Under-voltage and Phase-loss, faults can be set to Auto-Reset (see Fault Parameters). The starter will reset itself 60 sec. after voltage was fully restored provided no start signal exists.

Start-Up Procedure

Note: It is necessary to connect a motor to load

terminals otherwise “Wrong Connection” Protection is activated. Other loads such as light bulbs, resistors, etc. may also cause “Wrong Connection” (Fault).

Start-up procedure with start-stop buttons

1. Connect Control Supply. On and Stop LEDs will lit.

2. Review all parameters with Mode and Select keys Set parameters as required.

3. If necessary, return to Default Parameters (see “Service Mode” page 33).

4. Connect mains voltage to starter’s line terminals.

5. Set LCD to show “MOTOR FLA” (% of motor FLA).

6. Press Start. If motor starts to turn shortly after Start signal, proceed to Para 7. If not, increase “Initial Voltage” setting and start again. When, upon starting, initial inrush current and mechanical shock are too high decrease “Initial Voltage” settings and proceed to Para

7. Motor begins to turn. If speed accelerates smoothly to nominal, proceed to Para 8. If current during acceleration is too high, decrease “Current Limit” setting and proceed to Para 8. If motor speed does not accelerate to nominal, increase Current Limit setting.

8. Press Stop and wait until motor stops.

9. Slightly increase Initial Voltage and Current Limit settings to allow for load changes.

10. Press Start and see that motor is Acceleration Time to full speed is as required.

11. If acceleration time is too short, increase “Acceleration Time” setting.

12. Check total starting time and set Max. Start Time to approx. 5 sec. Longer than the maximum time required to complete the starting process.

Examples of starting curves

Voltage quickly increases to the Initial Voltage value and then gradually ramps-up to nominal. Current simultaneously and smoothly increases to reach Current Limit setting or less, before smoothly decreasing to the operating current. Motor speed will accelerate to full speed quickly and smoothly.

Voltage and current increase until current reaches “Current Limit value”. The voltage is held at this value until motor is close to nominal speed, then current will begin to decrease. The RVS-DN continues to ramp-up the voltage until reaching nominal. Motor speed smoothly accelerates to full speed.

Special starting – Using Dual Adjustment

Using two starting characteristics, the starter will accelerate to DA-IV reaching 100% current limit. After Tx (Imm. Relay delay) voltage to terminal 8 is switched off, using the standard characteristic to complete acceleration. Useful to prevent initial high acceleration.

Pump Control

Choosing a suitable Pump Curve (centrifugal Pumps)

Starting Curve

1. Adjust main parameters as necessary (FLA, FLC, etc..)

2. Set Starting Curve, Acceleration Time, Current Limit, and Initial Voltage to their default values (curve 0, 10 sec., 400% and 30% respectively).

3. Start the pump while watching the pressure gauge as the pump starts and look for overshooting (“Pressure Surge”) of the gauge needle above the target pressure. In case of over pressure, choose a peak torque reduction curve (Pump Control curve 1!).

4. Set Start Curve 1!, increase Acceleration Time to 15 sec. and reduce Current Limit to 350%. Start the pump and watch the pressure gauge while the pump starts.

5. In most cases, overshooting is reduced, if the overshoot persists, increase Acceleration time to 25 sec. (confirm with motor manufacturer) and

operating area

try again.

6. If the overpressure persists, increase Starting Curve setting to 2!, 3!, 4 (Torque) or 5 (Current Ramp) if necessary. Each increase in Starting Curve setting will reduce the Peak Torque, thus, reducing the overpressure and preventing the “Pressure Surge” during start.

7. To increase starting time above these maximums, employ “Special Starting” (page

32) with these techniques or incorporate Torque and Current characteristics.

Stopping Curve

1. Adjust main parameters as necessary (FLA, FLC, etc..)

2. Set Stop Curve and Deceleration Time, to their default values (curve 0, 10 sec., respectively).

3. Stop the pump, watching the pressure gauge and the check valve as the pump stops. Look for undershooting/overshooting (“Water Hammer”) of the gauge (which may abruptly stops the pump and the motor).

4. Select Stop Curve 1, increase Deceleration time to 15 seconds. Stop the pump and watch the pressure gauge and the rate of closing of the check valve as the pump stops. Abrupt stopping of the pump and motor will cause a loud audible noise emitted from the check valve.

5. In most cases, “Water Hammer” is reduced. If the “Water Hammer” persists, increase the time to 25 seconds (confirm with motor manufacturer) and try again.

6. If the “Water Hammer” persists, increase Stop Curve setting to 2!, or 3!. Each increase in stop curve will reduce the abrupt stop of the pump, thus, preventing the “Water Hammer” phenomenon.

7. If the extent of the water hammer was not reduced, increase to stop

curve # 4 to employ Torque Controlled deceleration.

Final torque during soft-stopping a pump motor

1. While decelerating, the check valve may close before Deceleration Time has elapsed, thus, allowing current to flow through stator winding causing unnecessary heat. Select Final Torque sensitivity to 1, and stop the pump, confirm that current stopped flowing through the motor shortly after the check valve closed.

2. If current still flows more than 3-5 seconds after check valve closure, increase Final Torque up to 10 if necessary, to stop current flow earlier.

(Optional) Alarms when motor insulation level decreases below set level. Alarm ceases automatically 60 sec. after resistance able set level. Check motor and cable insulation.

(Optional) Trips the starter when motor’s insulation level decreases below trip value. Check motor and cable insulation level.

(Optional) Trips the starter when motor’s thermistor resistance decreases below trip value. Check thermistor and cable’s resistance, check motor temperature near thermistor location.

Trips the starter if number of starts, during “Start Period” exceeds the preset number. Wait until motor and starter cool down – according to “Start Inhibit” setting.

Trips the starter if output voltage does not reach nominal at the preset max. Start time. Check FLA, FLC, and Max Start Time settings. Increase Initial Voltage, Current Limit & Max. start time or decrease Acceleration Time as necessary.

Trips the starter when:

1. Instantaneously when current exceeds 8.5 x Starter FLC.

2. During starting when current exceed 8.5 x Motor FLA.

3. During running when current exceeds 200-850%.

O/C Shear-Pin has a programmable delay of 0-5 seconds where the starter detects the fault and does not trip before time delay has elapsed (delay is override when current reaches 8.5 x Starter FLC).

Check that motor is not installed or Jammed. Check FLA, FLC settings. Check motor and cable connections. Perform a “Megger” test to verify motor and cable’s condition

• Check that “Megger” maximum voltage is no more than 500V!.

• Disconnect terminal 21 before performing a “Megger” test.

CAUTION

Trips the starter when current exceed the Overload Trip level and thermal register has filled up. Check FLA, FLC and Overload settings, check motor current, wait 15 minutes to let motor and starter cool down before restarting.

Trips the starter when line current drops below the preset level for the preset time. Check “Under Current Trip” and “Time Delay” settings, check line currents through L

Trips the starter when operating at slow speed for extended period of time. Check that operation time at Slow Speed is shorter than “Max Slow Speed Time” setting. Note: Motor and starter may be overheated when operating at slow speed for an extended period.

Trips the starter when one or more motor phases is not properly connected to starter’s load terminals or in case of internal disconnection in motor winding. If required, may be eliminated by using Dip Sw # 3 and wiring the soft-starter in generator mode (programming D.A. parameters accordingly*).

Trips the starter and prevents starting if any SCR is short-circuited or when motor windings are shorted. Check with an ohmmeter between L

-U, L2-V, L3-W; resistance > 20 K.

Check for no voltage on terminals U, V, W (from parallel system or an independent bypass). SCRs may fail due to: * High short current not protected by proper fuses

* High voltage spikes not protected by proper external Varistors. * Frequent starting at maximum conditions or fault conditions.

Heat-sink over-temperature. Trips the starter when heat-sink temp. rises above 85˚C. Improve cooling or use a by-pass contactor. Check that motor starting is not too frequent.

Trips the starter when a N.O contact between terminals 19-21 closes for over two seconds. Check contact position and cause of closure.

“Inside Delta” mode - Description

General information

• Mains current is reduced by 1.73 (3), namely for an

800A motor, an 820A starter will be selected, to operate “In-Line”. For “Inside Delta” starter, we calculate (800 / 1.73 = ) and select a 460A starter.

• Less heat dissipates in the cabinet

vs. the standard “In-Line” connection.

The attached

drawings are fo reference purposes only.

The starter must always be selected according to motor’s nominal current and starting conditions.

Important Notes:

• Wrong motor connection will cause serious damage to the motor windings.

• The sinusoidal shape of the current is imperfect (since each phase is separately fired and not influenced by other phase firing). As a result, higher harmonic content is incurred (THD), which can be as high as twice the THD value as in the standard “In-Line”.

• Higher motor heating is expected for the same motor size (due to the higher THD).

• Phase sequence must be correct; otherwise, “Phase Sequence fault” will trip the starter immediately (without any damage).

• Higher torques can not be obtained

• “Inside Delta” requires 6-wire to the motor.

• Factory preset - features and functions when “Inside

L2L3

Delta” mode is configured:

• No Pulse Start.

• No curve selection (Curve 0 !!).

• No Energy Save

• No Slow Speed

• No Phase sequence “Off” mode

Note :

For a high starting torque process, we recommend to use the starter in the “standard” connection (in-line).

WARNING

Beware Wrong connection of the starter or the Motor, will seriously damage the motor.
