3. TECHNICAL DATA
3.1 Introduction
The RVS-DN is a highly sophisticated and reliable soft starter designed for use with standard three-phase,
three-wire and six-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. This provides soft start
and smooth, stepless acceleration while drawing the minimum current necessary to start the motor.
The third generation, microprocessor based digital control provides unique features like pump control, slow
speed, electronic reversing and accurate motor protection. RVS-DN models can be supplied with options for
insulation protection, thermistor input & analog output, etc.
The optional RS 485 Communication with Modbus protocol or the optional Profibus protocol enables full

3.5.1 Preparation for Bypass Contactor
Under normal operating conditions the heat dissipated by an RVS-DN causes heating of the enclosure and
energy losses. The heating and losses can be eliminated by the use of a bypass contactor, which bypasses
the RVS-DN after completion of start-up so that motor current will flow through the bypass contactor.
In models RVS-DN 950A and up, current transformers CT1 and CT2 are mounted outside the RVS-DN and
need to be connected to the RVS-DN by the customer. In this case the customer MUST NOT ground the
secondaries of current transformers!
Heat dissipation from the RVS-DN is calculated as:
Ploss=3x1.3xI+FAN loss
where:
I represents motor current. Note that the motor current during the start process is higher than the motor rated
current.
FAN loss represents power loss caused by all internal fans (refer to section 10 page 99 for fan loss per
model).
For example, during start of a 820A motor when CURRENT LIMIT is set to 400%, heat dissipation can be
calculated as:
Ploss=3x1.3x4x820+150=12,792Watt≈12.8kW
While a 820A motor is running and the motor current is 820A, heat dissipation can be calculated as:
Ploss=3x1.3x820+150=3,198Watt≈3.2kW
When a bypass contactor is used this changes the previous calculation to:
Ploss=3x1.3x0+150=150Watt≈0.15kW
It is obvious that using a bypass contactor can significantly reduce energy consumption.
Notes:
•All models from RVS-DN 950A and up, RVS-DN 1000V and RVS-DN 1200V must be implemented with a
bypass contactor (see section 3.5.1.2 page 15).
•Bypass preparation is standard in models RVS-DN 85-170A.

Current flow during soft start and soft stop.
Bypass contactor is open.
15 • Technical Data
________________________________________________________________________________________________
Current flow during RUN when the bypass contactor bypasses the RSV-DN.
Current transformers CT1 and CT2 are able to measure motor current, thus the motor current
protections of the RVS-DN are operable.
Note:
If the RVS-DN is bypassed without using the preparation for bypass the following protections are not operable
during RUN:
•UNDER CURRENT
•O/C SHEAR PIN
•OVERLOAD TRIP
3.5.1.2 Maintaining Current Protection after Bypass Closes - RVS-DN 950-3000a
RVS-DN 950-3000A models are supplied without preparation for bypass. However bypass must be applied
for these models.
Current transformers CT1 and CT2 are supplied separately and must be connected to the RVS-DN as shown
below.
Note:
Do not ground current transformers secondaries!

3.5.2 Input Terminal 7 - Energy Save/Slow Speed/Reset
Input from a N.O. contact - selection between above functions is made from the keypad (refer to section
7.7.8 page 83) or through the communication (Modbus or Profibus).
When ENERGY SAVE function is selected - connect terminal 7 to control input voltage by a jumper for
automatic operation, upon load decrease.
When connected through a N.O. contact, closing the contact operates Energy Save.
When SLOW SPEED function is selected - connect control input voltage to terminal 7 before starting. When
start command is initiated motor will run at 1/6 nominal speed for 30 seconds maximum. Closing terminal 7
while motor is running will not have any effect.
When RESET function is selected - connect terminal 7 to control input voltage (use a N.O. momentary
contact) to reset the RVS-DN.
Refer to section 4.10 page 23 for the wiring diagram.
3.5.3 Input Terminal 8 - Dual Adjust/Reverse/Reset
Input from a N.O. contact - selection between above functions is made from the keypad (refer to section
7.7.8 page 83) or through the communication (Modbus or Profibus).
When DUAL ADJUSTMENT function is selected - connect terminal 8 to Control Input voltage to operate the
RVS-DN with the DUAL ADJUSTMENT characteristic. DUAL ADJUSTMENT characteristic is programmed as
explained in section 7.7.5 page 79. You can switch between the primary and DUAL ADJUSTMENT settings
before and/or during starting.
When dip switch #3 is set to on, DUAL ADJUSTMENT operates as D.ADJ.:GENERATOR PARAMETERS.
Use this mode if the normal starting process fails, i.e., SHORTED SCR or WRONG CONNECTION faults
occur and, after testing, operator is sure that SCRs, motor and motor connections are not faulty.
Refer to section 4.17 page 29 for D.ADJ.:GENERATOR PARAMETERS wiring.
Refer to section 9 page 95 for trouble shooting.
When SLOW SPEED REVERSE function is selected - connect Control Input voltage to terminal 8 to reverse
direction. In order to operate in SLOW SPEED REVERSE, terminal 7 must be programmed as SLOW SPEED
and Control Input voltage must be connected to terminal 7 as well.
You can give the reverse command before the motor is started or during operation at SLOW SPEED.
Connecting Control Input voltage to terminal 8 before motor is started, starts the motor in reverse direction.
Connecting Control Input voltage while motor is running at SLOW SPEED stops the motor for 0.6 – 2 sec
(according to motor size) before reversing its direction.
Refer to section 4.10 page 23 for wiring diagram.
When RESET function is selected - connect terminal 8 to Control Input voltage (use a N.O. momentary
contact) to reset the RVS-DN.
Refer to section 4.10 page 23 for the wiring diagram.
3.5.4 Output Terminals 10, 11 & 12 – Immediate/Shear Pin Relay
Programmable functions (refer to section 7.7.8 page 83):
IMMEDIATE (after start signal) - when immediate is selected, the relay is energized upon the START signal.
The relay is de-energized when one of the following occurs:
•Fault
•Control Supply outage
•STOP signal
When SOFT STOP is operated - the relay is de-energized at the end of the SOFT STOP process.
The relay incorporates on and off delays of 0-3600 sec. each.
The immediate relay can be used for the following purposes:
•Release a brake of a motor
•Interlock with other systems
17 • Technical Data
________________________________________________________________________________________________
•Signalling
•Delay the opening of a line contactor at the end of SOFT STOP, thus allowing current to decrease to zero
before opening the contactor
•Switch to / from Dual Adjustment settings with a time delay from the START signal (see Special Starting
section 8.2.3.1 page 92).
O/C SHEAR PIN detection - when O/C Shear-pin is selected, the relay is energized upon SHEAR-PIN
detection (RVS-DN’s trip can be delayed 0-5 sec).
In this case, the relay incorporates on and off delays of 0-5 sec. each.
The O/C SHEAR PIN relay can be used for the following purposes:
•Interlock with other systems
•Signalling
•Delay for operating a reversing combination of upstream contactors when SHEAR PIN is detected, thus
allowing clearing of a jam condition.
