Starter Selection
The HRVS-DN is a highly sophisticated and reliable
starter designed for use with standard medium voltage
three-phase, three-wire, squirrel cage induction motors.
It provides the best method of reducing current and
torque during motor starting.
The HRVS-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,
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 on a shield
twisted pair to a host computer.
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 HRVS-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: 2 starts per hour at
maximum conditions.

Built-in memory systems
The HRVS-DN incorporates 3 memory systems:
EPROMA read-only, non-volatile memory,
containing factory set parameters
(default) that cannot be changed.
EEPROMA 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.

3. Start parameters can be modified during
starting
process and will immediately affect the
operation. 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. After completion of the adjustments,
parameters should be stored in the EEPROM.
Storing of new parameters is possible at the
end of each Mode Page by pressing Store key
after “Store Enable” is displayed on the LCD.

Series contactor
• A Line contactor and by-pass contactor must be used
• To incorporate soft stop, use Run contact off delay to “Hold” the Line Contactor.
This system is used mainly when the HRVS-DN is retrofitted into an existing system, thus, reducing 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.
Notes:
1. It is recommended that terminals 1-3 shall be always connected to Control Supply.
2. Upstream contactor must be opened immediately after soft stopping. The upstream contactor can be
interlocked via 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 (after current reached zero). See Immediate / Shear-pin contacts delay – page 9.
•Ensure that auxiliary contact C1 closes together with or after the main contactor. The soft-starter provides a
500 mili seconds delay for the start signal. If it close before, Under Voltage fault will occur.
By-pass contactor
End of Acceleration contact is activated after an adjustable time delays “Run Contact Delay” – see page 26 at the end of
start-up period, closing the by-pass contactor.
•By-Pass Open failure will trip the system if the By-pass contactor is connected to L1, L2 and L3 instead to
L1b, L2b and L3b buses. If this type of connection cannot be avoided set By Pass open trip to DISABLE.
Warning: all current protections are lost.
The contact will return to its original position when:
• Soft Stop or Stop signals are initiated.
• Fault conditions occur.
When the by-pass contactor closes, current to the motor will flow through the by-pass. When a Soft Stop signal is given,
the End of Acceleration contacts return to its original position opening the by-pass contactor. Thereafter, the voltage
will gradually ramp down to zero to soft stop the motor.

Wiring Diagrams – Diesel Generator
FOR STARTING FROM GENERATOR ALWAYS TRY START CURVE 0 FIRST!
1. When starting from a Diesel – Generator, the voltage regulator (especially older type regulators) may be
affected during the starting process and cause a rapid voltage fluctuations. In these rare cases, the voltage
regulator must be upgraded – consult your Diesel-Generator Supplier.
2. When operating from Diesel Generator verify that power factor capacitors are not used.
3. In applications that may start both from generator and from mains, ensure that power factor capacitors, if used,
are disconnected before starting from the generator.
4. Ensure that Diesel Generator size is suitable. It is recommended that Generator KVA is 2.5 times motor KVA
or larger.
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 Generator

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 HRVS-DN incorporates 5 different starting curves:
Start Curve 0 – Basic curve. Uses less feedback
signals.
Use at beginning of commissioning and when other
curves do not give good starting process.
Start Curve 1 – Standard curve (Default). The most
stable and suitable curve for the motor that prevents
prolonged starting and motor overheating.
Start Curves 2, 3, 4 – During acceleration, before
reaching peak torque, the pump control program
automatically controls the voltage ramp-up to reduce
peak torque.

Note:
Normally starts 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
This feature includes two settings:
Pulse Level [% of FLA]
Pulse Time [sec.]
These settings allow to use the pulse:
•
To start high friction loads,

•

time.
After the end of the pulse time voltage is ramped
down/up to the current determined by the initial
voltage setting.
Pulse Start has no effect with Start Curve = 0.
Note:
Initial Voltage / Current
Determines the motor 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, which 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
U%

start signal.
If the initial voltage value is increased above the max
value, first line message changes to initial current.
Setting range is 100%-400% of motor FLA. When
initial current is set, starter causes current ramp instead
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 greater
current drawn from main voltage and faster
acceleration.
A setting that is too low may
prevent motor from completing
acceleration process and reaching
full speed. In general, this setting
I%
400%
should be set to a high enough
value in order to prevent stalling.
Note:
Current limit is not operating
100%
during Run and soft stop.
Acceleration Time
Determines the motor voltage
ramp-up time from initial to full
100%
U%
voltage. Range 1-30 sec. (consult
factory for extended range). It is
recommended to set acceleration
time to the minimum acceptable
value (approx. 5 sec).
1
30sec
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 reachs full speed before voltage
reachs nominal voltage, acceleration time
setting is overridden and cause the voltage to
ramp-up quickly to nominal.
3.
Starting curves 1, 2, 3 prevents quick ramp up.

Maximum Start Time
The maximum allowable starts time from start signal to
the 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 the 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 and reducing the voltage will
reduce torque so motor will smoothly decelerate to
stop.
The following
Stop curves
can be selected:
Stop curve 0 –
Basic curve. See note at page 17.
Stop curve 1 –
Standard default curve – voltage is
linearly reduced from nominal to zero.
Stop curves 2, 3, 4 –
In some pump applications, when
pumping to a high level, a considerable part of the
torque is constant and does not decrease with speed. It
may happen that during soft stop, when voltage
decrease, motor torque quickly falls below load torque
and motor will abruptly stall instead of smoothly
decreasing speed to zero.
Curves 2, 3, 4 designed

to prevent stall condition.

Note:
Normally use stop curve 1. If motor stalls
quickly instead of slowly decreasing its speed,
select stop curve 2, then 3 or 4 if necessary.
Stop Curve 5
– Torque curve.
Provides linear torque control.
With certain loads, may cause
linear deceleration.
Deceleration Time – Soft Stop
Used for controlled deceleration
of high friction loads.

during this time delay will result in LCD
displaying “Wait Before Restart: ___ 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 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 exceeds 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. It is required to protect the
thyristors (see fuse table in the appendix).
Overload (OL)
Inverse time electronic overload
becomes operational when RUN
LED is on.
t
The OL circuitry incorporates a
Thermal Memory Register, which
10
calculates the heat less the
dissipation of the motor. The starter
trips when the register fills up.

I%
500115
The thermal register resets itself 15
minutes after the motor stops.
The value is adjustable within 75-150% of motor FLA
and factory pre-set at 115%.
Tripping time at 500% FLA is adjustable within 1-10
seconds to allow trip curve selection.
ATTENTION
Overload protection is not operative during softor soft-stop.
Under Current
Operational when motor is running. Trips the starter
when motor current 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 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 Parameters. Auto
reset is activated 60 seconds after trip occurred.
Under Voltage Trip range: 50-90% Un (Line to Line)
Under Voltage delay range: 1-10 sec.
Note:
1. When voltage drops to zero (voltage outage)
the starter will trip immediately, overriding
the delay.
2. Auto reset can not be activated if start signal
is still connected.

Motor & Starter Protection
The over temperature protection is designed to operate
under normal conditions e.g. in the event of extended
perations frequent
starting at maximum conditions or repeated starting
under fault conditions can cause SCRs to overheat and
C to trip the
Over Voltage
Operational after start signal. It trips the starter when
main voltage exceeds the Over Voltage Trip set point
for an adjustable period of time longer than Over
Voltage Delay.
Range: 110 – 125% of Un (Line to Line)
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
seconds after trip occurred.
Note:
1. Phase loss might not be detected in lightly
loaded motors.
2. Auto reset can not be activated if start signal
is still connected.

IT trips the starter when starter is energized and phase
sequence is wrong.
Shorted SCR & Wrong Connections
Operational after start signal. It trips the starter if motor
is not properly connected to starter’s Load terminals,
when:
•
Internal disconnection in the motor winding is
detected.
•
In case one or more SCRs have been shorted.
•
Incorrect fiber - optic lead insertion.
Heat-sink Over Temperature
Thermal sensors are mounted on the heat-sink and trip
the starter when temperature rises above 85ºC.
External Fault 1 & 2
Operational when starter is energized. It trips the
starter when an external contact closes for more than 2
sec.
Unbalance Current Trip
Operational after start signal. It trips the starter when
current unbalance 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: 1-60sec.
Power ON & No Start
Operational upon main voltage connection. It trips the
motor when main voltage is connected to the HRVSDN for more than 30 sec. without a start signal.
This protection can be enabled or disabled via the fault
parameters setting menue.
By-pass Open
Operational when the by-pass contactor did not close
after End Of Acceleration contact signaled the pilot
(interposing) relay to close.

5. Set LCD to show “MOTOR FLA” (% of
motor FLA).
6. Press Start. If motor starts to turn shortly
after start signal, proceed to paragraph 7.
If not, increase “Initial Voltage” setting
and start again.
If initial inrush current and mechanical
shocks during starting are too high, decrease
“Initial Voltage” settings and proceed to
paragraph 7.
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 the motor
acceleration time to full speed is as
required.
11. If acceleration time is too short, increase
“Acceleration Time” setting.

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

GND FAULT TRIP
It operates when Ground Current exceeds the preset “GND FAULT TRIP” for more than
“GND FAULT DLY”.
PWR ON & NO
START
It operates upon main voltage connection and activated when main voltage is connected to
the HRVS-DN for more than 30 seconds without a start signal.
BY-PASS OPEN
It operates when the by-pass contactor did not close after EOA contact of the HRVS-DN
closes.
Note: This protection can be disable by setting By Pass open trip to disable when the By
Pass is connected in a separate in a separate cabinet such that the starter CT’s do not
measure motor current when the By Pass contactor is closed.

Trips the starter and prevents starting if any SCR is short circuited or when motor windings
are shorted or when firing is incorrect (fiber optic lead incorrectly inserted may cause this
fault).
Check with an ohmmeter between L1-U, L2-V, L3-W; resistance > 20 KΩ
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 temperature rises above 85˚C.
Improve cooling or use a by-pass control. Check that motor starting is not too frequent.
