Starter Selection
The starter should be selected in accordance with the
following criteria (see Ordering Information data).
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.
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 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 RVS-DN is designed to operate under the
following conditions:
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.
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.
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.
Note: For very frequent starts (inching applications),
the inching current should be considered as the
Full Load Ampere (FLA).

Installation
Calculating the enclosure size, for non-ventilated
metallic enclosure:
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.
Area (m2)
Where Area (m2) - Surface area that can dissipate heat
(front, sides, top).
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.
* 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 I2t and
fuses).
Note: For harsh environments, it is recommended to
order the starter with Option # 8 – Special Treatment
(printed circuit board coating).
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.
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%.
For size A, or when higher transients are expected,
additional external protection should be used (consult
factory).
Starter’s heat dissipation is approx. 3 x In (three times
the current in watts).
ATTENTION
When Start signal is initiated and a motor is not
connected to load terminals, the Wrong Connection
protection will be activated.
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.

WARNING
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.
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!
Fan

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

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.
Main power and Start signal are switched on upon
closure of the series contactor. The starter will operate
as long as the series contactor is closed.
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.
Control supply obtained from main voltage must match
starter’s Control Supply voltage.
Notes:
1. It is recommended that terminals 1-3 be
always connected to Control Supply.

This system is mainly used when the RVS-DN is
retrofitted into an existing system, to reduce
modifications in existing installations.

When the by-pass contactor closes, current to the
motor will flow through the by-pass.
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.
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.
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.
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.
Ensure that auxiliary contact C1 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.

Used for Two Speed Motors:
The start-stop control is by a N.O auxiliary contact in
each of the two series contactors C1 & C2. Closure of
either contactor will supply main power and a start
signal to the RVS-DN.
* 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).
Control voltage, obtained from main, must match the
starter’s Control Supply voltage.
* 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:
1. It is recommended to employ a mechanical
interlock between the Forward and Reverse
Contactors.
2. It is required to delay the transfer between
opening of one contactor and closing of
second contactor.
3. Phase Sequence fault must be disabled to
operate Reversing Contactors at the Line
Input of the soft-starter.
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:
*

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).

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

Note: Always starts with Start Curve 0. If
towards end of acceleration, peak torque
is too high (pressure is too high), proceed
to Curve 1, 2, 3 or 4 if necessary.
A setting that is too low may result
in prolonged time until motor
begins to turn. In general, this
setting should ensure that the motor
begins turning immediately after
start signal.
Speed RPM

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
I%
acceleration process and reaching
400%
full speed. In general, this setting
should be set to a high enough
value in order to prevent stalling.

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%
Tacho Feedback, 0-10VDC (Optional)
Provides linear acceleration and
deceleration curves according to
rpm feedback. 12 tacho gain levels
can be selected for closed loop
control starting and stopping.
Note: Consult factory for additional
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

Determines motor’s voltage ramp100%

Range 1-30 sec. (consult factory for

to set Acceleration Time to the
minimum acceptable value (approx.

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.
18
sec
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.
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.

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 MΩ
• Trip level, Range : 0.2 – 5 MΩ
When insulation decreases below Alarm Level set
point for more than 120 sec., the LCD displays
ALARM:
INSULATION LEVEL and shows the value in MΩ.
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.
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
motor stops.
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 KΩ
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
t

500 I%
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.
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.
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.
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).
Note:
When voltage drops to zero (full voltage outage) the
starter will trip immediately, overriding the delay.
20
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.
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
before the heatsink reaches 85°C to trip the thermal
sensors.
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.
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 as long as Start signal exists.
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.
Note:
Auto- Resetting is not possible as long as Start signal
exists.

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
Pump control during
overshoot persists, increase Acceleration time to
operating area
25 sec. (confirm with motor manufacturer) and
Voltagae
Torque
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,
Peak
reducing the overpressure and preventing the
Torque
“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.

PHASE SEQUENCE
Trips the starter when line voltage drops below the preset level for the preset time.
Check “Under Voltage Trip “ and “Time Delay” settings, check line voltages on L1, L2,
L3. When voltage drops to zero, the starter trips immediately with no delay.
Trips the starter when line voltage increases above a preset level for a preset time.
Check “Over Voltage Trip” and “Time Delay” settings, check line voltage on L1, L2, L3.
Trips the starter if 1 or 2 phases are missing. Check line voltages related to terminal 21 is
connected correctly (see page 8). Check that frequency variations are between 40-65Hz.
Trips the starter if line phase sequence is wrong. Check line phase sequence, and if wrong,
swap two wires on line side. If motor now rotates in the wrong direction, swap two wires
on load side.
MAX SLOW SP
TIME
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.
WRONG
CONNECTION
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*).
SHORTED SCR
Trips the starter and prevents starting if any SCR is short-circuited or when motor
windings are shorted.
Check with an ohmmeter between L1-U, L2-V, L3-W; resistance > 20 KΩ.

“Inside Delta” mode - Description
General information
Important Notes:
• 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 L1
vs. the standard “In-Line”
connection.
V'
• 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
Delta” mode is configured:
• No Pulse Start.
• No curve selection (Curve 0 !!).
• No Energy Save
• No Slow Speed
• No Phase sequence “Off” mode

The starter must always be selected according to motor’s nominal current and starting conditions.
For “Inside Delta” connection, the “In Line” KW ratings were multiplied by 1.73.

Overload Trip Time Calculation
Note: In overload procedure, current is limited to 5 x Motor FLA to prevent saturation in calculation, so trip time at 5 or
8 times motor FLA will be identical.
The approximate trip time is given in the following equation:
O/L Trip Time =

I % = Actual Current ×

Motor FLA
OLT = Overload Trip setting (default 115%)
OLD = Overload Delay setting – trip delay at 5 x Motor FLA, (default 4 sec).
Example 1:
Motor FLA = 80A, actual current = 120A,
I% = 120 x 100 / 80 = 150%
If settings are as in default then
O/L Trip Time =
