Starter Selection
1
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
2
Area (m2)
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 non-
condensed 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.
Additional Ventilation
RVS-DN
General purpose enclosure
Fan on air outlet
RVS-DN
Non-ventilated enclosure
Fan, creating air circulation
Fan
Calculating the enclosure size, for non-ventilated
metallic enclosure:
Where Area (m2) - 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 I2t 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
3
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 start-
up, 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 by-
pass 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.

Control supply before C1
This system is mainly used when the RVS-DN is
retrofitted into an existing system, to reduce
modifications in existing installations.
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.
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.
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 C1closes 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.

L1 L2 L3
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.

Mechanical Interlock
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.
Control voltage, obtained from main, must match the
starter’s Control Supply voltage.
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

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.

• External Control - Connect the jumper to terminal B
Connect terminal 2 to Control Supply through an
external contact. Fan(s) will operate when the
external contact closes and stop when it opens.
• Automatic operation – Connect the jumper to
terminal C. Fan(s) will operate automatically for a
few minutes after start. The fan(s) will stop
automatically a few minutes after stop signal.
WARNING
1. The starter is supplied with the internal
jumper connected to terminal A, for
continuous operation. If changed, it is the
Customer’s responsibility to operate the
Fan(s).
2. Use only when by-pass contactor is utilized.
Built-in memory systems
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.

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.

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.
+10Vdc

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

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
should be set to a high enough
value in order to prevent stalling.
Note: Current limit is not operating
during Run and Soft stop.

Acceleration Time
Determines motor’s voltage ramp-

to set Acceleration Time to the
minimum acceptable value (approx.
5 sec).
U%

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 ramp-
up to nominal.
3. Using starting curves 1, 2, 3 prevents quick
ramp up.
